Berdasarkan data Badan Pengatur Jalan Tol (BPJT), hingga tahun 2020 terdapat 57 ruas jalan tol (dengan panjang total 1961.91 km) yang telah terbangun dan beroperasi di Indonesia dimana terdapat 472 gerbang tol dalam ruas jalan tol tersebut. Secara umum sistem struktur yang digunakan pada gerbang tol berupa portal baja dengan rangka atap menggunakan sistem rangka batang (truss). Pada standar desain, ditetapkan bahwa struktur gerbang tol harus memenuhi kondisi batas kekuatan (strength) dan layan (serviceability). Pada kondisi batas layan (serviceability), struktur harus didesain agar lendutannya lebih kecil dibanding lendutan izin. Jika kondisi batas layan (serviceability) belum terpenuhi, ada beberapa metode yang dapat dilakukan untuk mengurangi lendutan struktur seperti memperbesar dimensi profil baja, menambahkan pengaku (bracing) untuk meningkatkan kekakuan struktur, mengubah geometri struktur, dll. Dalam penelitian ini akan dikaji pengaruh penggunaan cross-brace pada bagian ujung struktur rangka batang dalam mengurangi lendutan struktur. Selain itu juga akan diteliti pengaruh cross-brace terhadap periode natural dan berat sendiri struktur. Penelitian ini dilakukan dengan mengambil studi kasus pada struktur gerbang tol pada ruas jalan tol Semarang-Batang dengan panjang bentang 31 m. Berdasarkan analisis yang dilakukan, disimpulkan bahwa penggunaan cross-brace dapat menurunkan periode natural dan lendutan di tengah bentang struktur berturut-turut sebesar 0,002 s/d 0,091 detik dan 0,9 s/d 1,5 mm. Namun demikian, penggunaan penggunaan cross-brace meningkatkan berat sendiri struktur sebesar 0,247 s/d 3,755 ton.

Suspended Particulate Matter (SPM) adalah polutan berbahaya yang umumnya diakibatkan oleh kontribusi bahan buangan dari asap kendaraan dan mesin pabrik. Penelitian ini untuk mendeskripsikan perbandingan polutan SPM pada tiga wilayah Jakarta yaitu Ancol, Monas dan Glodok berdasarkan analisis data SPM bulanan. Metode pengolahan dalam penelitian adalah analisis kuantitatif dengan memanfaatkan data bulanan SPM dari BMKG dari tahun 2006-2019. SPM diukur menggunakan alat HV Sampler dengan menggunakan kertas filter yang diputar dengan kecepatan tinggi. Hasil penelitian menunjukkan bahwa rata-rata konsentrasi SPM tertinggi terjadi di kawasan perdagangan Glodok (313 μgr.m-3), tertinggi kedua adalah Ancol (223 μgr.m-3) dan terendah terjadi di Monas (193 μgr.m-3). Nilai ambang batas aman SPM di udara adalah 230 μgr.m-3. Frekuensi kejadian SPM di atas ambang batas berturut-turut dari tertinggi hingga terendah adalah Glodok (73%), Ancol (44%) dan Monas (27%). Berdasarkan konsentrasi SPM di atas ambang batas secara rata-rata tahunan, untuk wilayah Ancol berlangsung lebih dari 6 bulan yaitu pada bulan Mei-Nopember, untuk wilayah Monas pada Juni-Agustus, namun untuk wilayah Glodok SPM berlangsung sepanjang tahun dari Januari hingga Desember. Buruknya kualitas udara di Glodok ini menunjukkan bahwa wilayah Glodok perlu mendapatkan penanganan agar udara semakin bersih dan nyaman untuk kesehatan dan kehidupan masyarakatnya.

Full textAbstract:
Batang Anai is a river that crosses through four administrative regions in the West Sumatra Province with a catchment area of about 498 km2. The upstream is a steep topography because it is located in west part of the Marapi mount. While the middle and lower reaches are mild since in the lowlands. The flow empties into the Indian Ocean. These conditions make this river meandering in the middle and lower reaches. The river mouth is influenced by the tide in which resists sedimentation toward the ocean. As a result, the capacity of the river cross-section decreases which eventually causes flooding. In 2013, the lower reach was dredged. In 2015, however, the river mouth was covered back by sedimentation by two-meter height in some points. Bathymetry was measured before and after dredging. This study is conducted to determine a design flood-discharge that caused sedimentation based on the 2015 bathymetry data by simulation using the SMS software, i.e. the RMA2 module for modelling hydrodynamics and the SED2D module for modelling sedimentation. The attention is paid to see both flow patterns and sedimentation profiles. The model scenarios consider by either including or excluding the Batang Kandis flow. Batang Kandis is a tributary of Batang Anai which empties into near its river mouth. The design flood-discharges for simulation are varied according to the return periods of 2, 5, 10, 25 and 50 years. The bathymetry data used for simulation are the 2013 one after dredging. All the simulation results are then compared to the 2015 bathymetry data. The hydrodynamic model in which the Batang Kandis flow included gives velocities close to those from the field for all return periods. The results of the sediment model using the flood flow with a 5-year return period, that’s Batang Anai is 1060 m3/s and Batang Kandis is 268.5 m3/s, show that the sedimentation profiles are closed to the 2015 bathymetric measurement data.

Full textAbstract:
BatangLampasi River was located in Talawi village, Nagari Koto Nan GadangPayakumbuh, about 30 km from Bukittinggi, with 48.19 km river length and around 226 km2 Cathment Area. The river flow carries a lot of sediment material, causing siltation on the riverbed which causes the river to overflow in the surrounding area. Sediment transport was triggered by Lampasi watershed erosion, that especially in the upstream section and settling on the riverbed. Prediction of depth decrease caused by sedimentation was conducted. Theoretical flood discharge determined used Nakayasu method. Sediment yield caused by land erosion determined by USLE equation and will compared with total sediment transport that calculated for 5 years return period with Yang's, Engelund Hansen, Ackers and White's methods. HEC-RASS 4.0 was used to find the high of flood water level and also as input hydraulics term to calculating transport sediment. The equivalent value approaching sediment yield was Yang's method where the sediment transport value is 21294,763 tons / year with sediment thickness of 27.24 cm / year. With these deposits thickness we can see from HEC-RASS 4.0 modeling the elevation of high flood water during normal conditions and the presence of thick sediment deposits.

Spice Route has become one of the main issues in the cultural historical studies of Indonesia recently. The discussion is still attached to effort to understand the existence of spice route as the part of the extensive trade system that have been initiated by the history of contact and interaction with the traveler from Western Asia; China; and the European explorers. There were almost no discussion that tried to explore the nature of the spice route prior to the contact with the Mainland Asia and the European. Including in the Maluku Archipleago. This paper discuss the formation process of the spice trade system in the prehistoric period and early historic period in Maluku from the archaeological perspective. The approach that has been adopted in this research is bibliographical studies. This paper found that the trade system and exchange in Maluku has been initiated since the prehistoric period as has been highlighted by the arcaheological studies in the region. Jalur rempah kembali menjadi salah satu isu yang mengemuka dalam diskusi sejarah budaya Nusantara setahun terakhir. Dimana wacana yang mengemuka umumnya masih mengamati keberadaan jalur rempah sebagai jejaring yang dibentuk oleh sejarah kontak dan interaksi dengan para penjelajah dari Asia Barat; Tiongkok dan terutama para pendatang Eropa. Hampir tak ada diskusi yang mencoba mengamati kemungkinan tumbuh kembang jalur niaga ini di era yang jauh lebih awal. Termasuk di Kepulauan Maluku. Makalah ini mencoba mengamati proses pembentukan jaringan niaga dan perdagangan rempah serta aneka komoditi eksotik di masa prasejarah dan awal sejarah di Kepulauan Maluku dari sudut pandang studi arkeologi. Pendekatan yang digunakan adalah kajian pustaka. Hasil kajian menemukan bahwa jaringan niaga dan pertukaran di Maluku telah dibentuk semenjak masa prasejarah sebagaimana ditunjukkan oleh ragam hasil penelitian arkeologi.

Full textAbstract:
Muhammad Syahrur is one of the figures who is concerned in the issue of female Aurat. Although his presence is very controversial, but he still tries to formulate his own concept. According to him, Allah SWT has set the period of Aurat concept since the time of the Prophet Adam and Eve. In fact, for him the measurement of Aurat is ashame and has nothing to do with halal and haram. Through the Theory of boundary, Syahrur sets minimum and maximum limits to deconstruct the concept of females’ Aurat. However, this method is considered wrong because it is to eliminate the sacredity of religious texts and contradict with the opinions among majority of scholars.

Flood is a natural hazard. It happens when the water in a river channel is beyond the capacity of the channel to carry while the overflowing water is called as floodwater. Flood causes damage to life and property when it strikes a vulnerable population in the affected area. There are several townships located along Batang Rejang such as Kapit, Song, Kanowit and Sibu. The main objective of this paper is to develop a river model to map the extreme events for Batang Rejang. The method used in is river modelling by using InfoWorks RS software. This method is simulating the Batang Rejang in order to view the behaviours of the river in response to conditions and effects of extreme events over a given period of time. Flood maps computed from InfoWorks RS are for flood extent analysis as it provides insights to the damage for different locations at different flows. The maps are also useful for related authorities or parties to locate human activities at the catchment area and to carry out emergency flood plans in the future.

Abstract This paper positions itself as a study that portrays the Keroncong Wayang Gendut (Congwayndut) performance, as performance art that reflects structural functionalism. Because Congwayndut explicitly contained aspects of structural functionalism. In this paper, Congwayndut is positioned as an organism that has a structure and functions socially and culturally. Congwayndut is one of the many performing arts groups capable of interpreting traditional art in contemporary, meaning that it responds to the millennial generation with the construction of traditional performances, namely shadow puppet art. . Congwayndut has an important role in the development process or as a performance art model that accommodates other art disciplines, including music, wayang, theater, script, visuals, dramaturgy, which are combined as a typical Indonesian performance art prototype. Therefore, the structural-functional point of view emerged, as a step to explain to the public about the cultural phenomena experienced by Congwayndut. Structural functionalism was born as a reaction against the theory of evolution. If evolutionary studies aim to establish the stages of human cultural development, then structural-functionalism studies aim to build a social system, or social structure, through the study of the functioning patterns of relations between individuals, between groups. -groups, or between social institutions in a society, at a certain period of time. Keywords: Congwayndut, Cross-Border Performing Arts, Structural Functionalism Abstrak Tulisan ini, memposisikan diri sebagai kajian yang memotret pertunjukan Keroncong Wayang Gendut (Congwayndut), sebagai seni pertunjukan yang merefelksikan fungsionalisme struktural. Karena di dalam Congwayndut secara eksplisit terkandung aspek fungsionalisme struktural. Congwayndut di dalam tulisan ini diposisikan sebagai organisme yang memiliki struktur, dan memiliki fungsi secara sosial budaya.Congwayndut adalah satu satu dari sekian banyak kelompok seni pertunjukan, yang mampu menafsir seni tradisi secara kekinian, artinya merespon generasi milenial dengan konstruksi pertunjukan tradisi yakni kesenian wayang kulit. Congwayndut memiliki peran penting dalam proses pengembangan atau sebagi model seni pertunjukan yang mengakomodir disiplin seni yang lain, ada musik, wayang, teater, naskah, rupa, dramaturgi, yang dijadikan satu sebagai purwarupa seni pertunjukan yang khas Indonesia. Oleh sebab itu lah sudut pandang struktural fungsional muncul, sebagai langkah untuk menjelaskan kepada publik, tentang gejala fenomena budaya yang dialami oleh Congwayndut. Fungsionalisme struktural lahir sebagai reaksi terhadap teori evolusi. Jika tujuan dari kajian-kajian evolusi adalah untuk membangun tingkat-tingkat perkembangan budaya manusia, maka tujuan dari kajian-kajian fungsionalisme struktural adalah untuk membangun suatu sistem sosial, atau struktur sosial, melalui pengajian terhadap pola hubungan yang berfungsi antara individu-individu, antara kelompok-kelompok, atau antara institusi-institusi sosial di dalam suatu masyarakat, pada suatu kurun masa tertentu.

ABSTRACTThis research had been conducted from December to March 2015 at Horticultural Seed Center, Marpoyan, Pekanbaru. The study aimed to determine the effect of the type of rootstock and the storage period of buds as well as the interaction between both of them towards its growth. This study was conducted experimentally by using completely randomized factorial design (CRFD) consisting of two factors and seven replications. The first factor was type of rootstock (B1: Japanese Citroen, B2: Rough Lemon) and the second factor was storage period of buds (M0: directly grafted, M1: 1-day storage period, M2: 2-day storage period, M3: 3-day storage period). Parameters measured were growth percentage of buds, bud burst time, length of buds, number of leaves and diameter of buds. The results showed that the Rough Lemon rootstock had a significant effect on the number of leaves, length of buds, bud burst time, diameter of buds and equally effect on the growth percentage of buds. Storage period of the buds did not significantly affect the growth of the grafted Siam Madu citrus seedlings.. The interaction between the type of rootstock and the storage period of buds only occurred in the bud burst time only.

Full textAbstract:
Playback of bird songs is a useful technique for species detection; however, this method is usually not standardized. We tested playback efficiency for five Atlantic Forest birds (White-browed Warbler Basileuterus leucoblepharus, Giant Antshrike Batara cinerea, Swallow-tailed Manakin Chiroxiphia caudata, Whiteshouldered Fire-eye Pyriglena leucoptera and Surucua Trogon Trogon surrucura) for different time of the day, season of the year and species abundance at the Morro Grande Forest Reserve (South-eastern Brazil) and at thirteen forest fragments in a nearby landscape. Vocalizations were broadcasted monthly at sunrise, noon and sunset, during one year. For B. leucoblepharus, C. caudata and T. surrucura, sunrise and noon were more efficient than sunset. Batara cinerea presented higher efficiency from July to October. Playback expanded the favourable period for avifaunal surveys in tropical forest, usually restricted to early morning in the breeding season. The playback was efficient in detecting the presence of all species when the abundance was not too low. But only B. leucoblepharus and T. surrucura showed abundance values significantly related to this efficiency. The present study provided a precise indication of the best daily and seasonal periods and a confidence interval to maximize the efficiency of playback to detect the occurrence of these forest species.

Metode penelitian yang digunakan yuridis normatif dengan menggunakan data sekunder yang terdiri bahan hukum primer dan bahan hukum sekunder serta analisa data bersifat kualitatif. Pengawasan DPRD Kabupaten Batang terhadap Perda APBD belum berjalan maksimal yang disebabkan fungsi pengawasan DPRD Kabupaten Batang lebih didominasi pengawasan teknis-fungsional daripada pengawasan politik. Polla pengawasan DPRD Kabupaten Batang belum berorientasi pada visi-misi, tujuan dan sasaran pembangunan Kabupaten Batang 2012-2017. Faktor-faktor yang mempengaruhi pengawasan DPRD Batang terhadap pelaksanaan Perda APBD Batang 2016 adalah faktor hukum, aparat penegak hukum, fasilitas dan sarana prasarana penegakan hukum dan faktor masyarakat (Budaya).

Full textAbstract:
Speeding is one of the risk factors for road traffic crashes and deaths, especially for vulnerable road users. Research shows that increasing vehicle speed by 1 km/h can increase 4% -5% of fatal crashes. However, several other studies show that crashes are caused more by speed dispersion than by average speed vehicles in the traffic. This study aims to determine the effect of speed limit violations on the rate of a motorcycle crash on the national road in Bandung City. Although the proportion of motorcycles that violates the speed limit is quite high (40%), it turns out the result of this study indicates that the rate of motorcycle crash does not seem to be affected by the proportion of motorcycle in the traffic that violates the speed limit. Crashes involving motorcycles are more prevalent in the highest flow period than in the free flow conditions where the proportion of motorcycle that violates the speed limit is the highest.
Mengendara dengan kecepatan tinggi merupakan salah satu faktor risiko penyebab kecelakaan lalu lintas dan kematian akibat kecelakaan lalu lintas, terutama pada kelompok pengguna jalan rentan. Penelitian menunjukkan bahwa peningkatan kecepatan kendaraan sebesar 1 km/jam dapat meningkatkan 4%-5% kecelakaan fatal. Namun beberapa penelitian lainnya menunjukkan bahwa kecelakaan lebih disebabkan oleh adanya variasi kecepatan di dalam arus dibanding kecepatan rata-rata kendaraan di dalam arus. Penelitian ini bertujuan untuk mengetahui pengaruh pelanggaran batas kecepatan terhadap tingkat kecelakaan sepeda motor di jalan nasional Kota Bandung. Walaupun proporsi sepeda motor yang melanggar batas kecepatan cukup tinggi (40%), ternyata hasil penelitian mengindikasikan bahwa tingkat kecelakaan sepeda motor tampaknya tidak dipengaruhi oleh proporsi sepeda motor di dalam arus yang melanggar batas kecepatan. Kecelakaan yang melibatkan sepeda motor justru lebih banyak terjadi pada kondisi arus tertinggi dalam satu hari dibanding pada kondisi arus lengang dimana proporsi sepeda motor yang melanggar batas kecepatan paling banyak.

Among the locations with traces of Austronesian cultural remains is the information about the diaspora of Research reveals that the continuing megalithic tradition. The problem is: if megalithic culture was brought by migrants in which Austronesian period did the menhirs should be placed, the proto-historic or recent Austronesian; how is the dispersal pattern of the menhirs; and who were the bearers of the culture. Therefore we have to reveal the form and dispersal of the megalithic culture and Austronesian migration in Lima Puluh Koto Area. The aim of this research is revealing cultural history through the migrant's adaptation within the perspective of Austronesian diaspora. Thus information about the diaspora of the Austronesians and the ethnogenesis of Indoneisan nation can be recognized. Research reveals that the continuing megalithic tradition which is used the qualitative method and assumed base on archaeological remains at Lima Puluh Koto area is a distribution of menhirs, that forms clusters in accordance with nagari (state) at certain area, and they are dispersed up to the hilly area. Some of these menhirs have sacred function but there are also those with profane functions like marks of village, house yard, or street boundaries, as well as the marker of village or hamlet roads.Diaspora Austronesia menunjukkan kurang lebih 60% penutur tinggal di Indonesia. Salah satu lokasi jejak Austronesia adalah di Kabupaten Lima Puluh Koto, Sumatera Barat, yaitu sebaran menhir yang mencapai ratusan jumlahnya. Bentuk budaya Austronesia dikenal sebagai budaya yang meneruskan tradisi-tradisi masa prasejarah dan berlanjut pada masa sejarah, seperti tradisi megalitik. Permasalahannya adalah, apabila budaya megalitik dibawa oleh para migran, pada periode Austronesia protosejarah ataukah Austronesia masa kini menhir-menhir tersebut berada?, bagaimana pola sebaran menhir-menhir tersebut? dan siapa pendukungnya?. Penelitian ini berusaha mengungkapkan bentuk dan persebaran budaya megalitik dan migrasi Austronesia di Kawasan Lima Puluh Koto. Maksud dan tujuan penelitian ini adalah untuk mengungkapkan sejarah kebudayaan dan adaptasi kaum migran dalam perpekstif diaspora Austronesia, sehingga memperkaya informasi tentang diaspora Austronesia dan asal-usul etnogenesis bangsa Indoensia.

Full textAbstract:
The reproductive characteristics of mahseer, Tor. tambroides, were studied in Manna River and Batang Tarusan River, which are located on each side of Western Sumatera River. The reproductive period of T. tambroides is largely consistent with that described for the species in other areas, however monthly variations in the extent and timing of peak spawning are recorded. The analysis of the sex ratio indicates an increase in the percentage of females with size, more marked in largest sizes. Seasonal patterns in the occurrences of spawning showed that the spawning season in Manna River lasted was similar with that in Batang Tarusan River, although a second prominent increase of GSI was observed in April and September in Manna River, meanwhile the GSI of Batang Tarusan River fish were below 2 without an apparent variation. L50s of Manna River and Batang Tarusan River mahseer were estimated as 24.5 cm and 20.66 cm, respectively, indicating a high variability in size at first maturity of the mahseer population. Our study provides some important information on the reproductive biology of T. tambroides that will be helpful in similar studies and contributed to fisheries management of this species.

Full textAbstract:
One of the consequences of the ongoing climate change is the increasing likelihood of extreme precipitation frequency in the future, which causes the declining trend of total precipitation that affects water debits in the watersheds and brings difficulties to a city like Padang that is situated near the watersheds. In order to elaborate on this, a number of extreme precipitation indices recommended by ETCCDMI was utilized to assess the extreme precipitation condition for the period 1975-2013. These indices were calculated based on the rain-gauge stations along the watersheds in and around Padang. Before processing the data, a series of homogeneity test were undertaken to make sure the data were comparable. The results showed that there was a significant declining trend on the total annual precipitation (PRCPTOT), an increasing trend of the number of days without rain (R0) and a decreasing frequency of the number of days with precipitation of more than 50 mm in the Batang Kuranji Watershed. The results suggested that atmospheric circulations, such as El Nino and positive Dipole Mode, have played their role on the trend as a result of their intensified frequency due to global warming.

Intisari DAS Citarum Hulu merupakan salah satu subdas yang paling berpengaruh di DAS Citarum dengan Waduk Sagulingnya. Besarnya debit yang masuk ke waduk menjadi sangat penting demi keberlangsungan kinerja waduk tersebut, misalnya untuk pembangkit listrik. Penelitian ini bertujuan untuk mengetahui karakteristik kekeringan hidrologi, relasinya dengan curah hujan, dan analisis frekuensi kejadian kekeringan hidrologi di DAS Citarum Hulu. Data dari pos duga air Nanjung digunakan dalam menentukan ambang batas kekeringan hidrologi yang kemudian diperoleh karakteristik kekeringan hidrologi. Hasil menunjukan bahwa rata-rata periode kekeringan di DAS Citarum Hulu terjadi mulai dari bulan Juni hingga Oktober. Terdapat keterlambatan antara waktu curah hujan turun dan waktu ketika debit naik akibat input dari curah hujan. Hasil analisis frekuensi menunjukan bahwa kekeringan maksimum yang terjadi pada tahun 1994 memiliki periode ulang 52 tahun dan kekeringan sering terjadi dengan durasi kurang dari 20 hari. Abstract Citarum Hulu is one of the most influential Citarum sub-basin with the Saguling Reservoir. The amount of discharge into the reservoir is very important for the sustainability of the reservoir's performance for power plants in example. This study aims to determine the characteristics of hydrological drought, its relationship with precipitation, and frequency analysis of hydrological drought occurrence in Citarum Hulu. Data from Nanjung post are used in determining the threshold of hydrological drought which then acquired the characteristics of hydrological drought. The results showed that the average period of drought in Citarum Hulu occurred from June to October. There is a lag between the time when rainfall drops and the time when the discharge rise due to the input of rainfall. Frequency analysis results showed that the maximum drought that occurred in 1994 had a 52-year return period and drought often occurs with a duration of less than 20 days.

<p>Water stress is a very important limiting factor for cotton cultivation in Jeneponto District, South Sulawesi Provine. Therefore, it is necessary to optimize water resources. One alternative is to obtain potency of water resources using soil-climate-crop simulation model to calculate ETR/ETM ratio (water satisfaction index). ETR/ETM ratio describing efficiency of water used by the plant. Based on the ratio, scenario of proper planting period can be predicted to minimize drought risk. Based on this idea, an experiment was conducted to mapping of planting periods and water used to enhance the expansion of cotton plantation. The results of research show that potential planting period for Bangkala and West Bangkala districts start from the 3rd dekad of September until the 1st dekad of January, while the best period is on the 1st dekad of November. Potential of planting period for Bontoramba and Turatea districts starts from the 3rd dekad of September until the 1st dekad of May, while the best period is on the 3rd dekad of November. In addition, the appropriate planting period for Batang, Kelara, and Rumbia districts start from the 3rd dekad of September until the 3rd dekad of April, while the best period is on the 1st dekad of December. Requirement for supplementary irrigation for 140 days after planting is about 180-304 mm. However, common necessity of cotton supplementary irrigation for 1-35 day is about 25 – 51 mm, while that is during flowering and fruiting (35 -60 day after planting), ripening (60-105 day after planting), and ripening (105-140 day after planting), are about 40-62, 115-135, 0-68 mm, respectively. It is concluded, deficit and surplus of water for less than 60 dap is not significantly influence plant production, but that is for 60 – 105 day after planting significantly reduces yield of the plant.</p>

ANALISISPENGATURAN POSISI CONTROL RODS PADA KONSEP REAKTOR DAYA EKSPERIMENTAL INDONESIA PASCA REACTOR SCRAM POST REACTOR SCRAM CONTROL RODS POSITION ADJUSTMENT ANALYSIS FOR THE INDONESIAN EXPERIMENTAL POWER REACTOR CONCEPT. ABSTRAK ANALISIS PENGATURAN POSISI CONTROL RODS PADA KONSEP REAKTOR DAYA EKSPERIMENTAL INDONESIA PASCA REACTOR SCRAM. Telah dilakukan analisis simulasi pengaturan posisi batang-batang kendali untuk melanjutkan operasi reaktor daya eksperimental (RDE) paska scram setelah beroperasi pada periode waktu tertentu. Pengendalian reaktivitas pada reaktor RDE yang akan dibangun di Indonesia dengan rujukan high temperature gas reactor (HTR) 10 MWt, dilakukan dengan 10 pasang batang-batang kendali atau control rod (CR). Apabila terrjadi kondisi abnormal maka CR secara otomatis akan jatuh tersisip ke dalam reflektor reaktor sehingga reaktor scram dan berada pada kondisi subkritis. Untuk melanjutkan operasi reaktor pasca scram diperlukan analisis terkait pengaruh reaktivitas negatif dari Xenon dan suhu. Pada makalah ini disajikan hasil simulasi yang dilakukan untuk penentuan posisi CR paling optimum untuk melanjutkan operasi reaktor, menggunakan simulator PCTRAN-HTR. Simulasi dilakukan pada variasi 70%, 85% dan 100% dari tingkat daya penuh dan dengan variasi waktu operasi 50 s, 10.000 s, dan 20.000 s di mana setelah reaktor beroperasi pada tingkat-tingkat daya dan waktu operasi tersebut reaktor mengalami scram. Untuk melanjutkan operasi lagi maka CR harus dinaikkan lagi dan diatur ke posisi tertentu sampai reaktor mencapai kondisi kritis lagi pada tingkat daya nominal tersebut. Hasil yang telah diperoleh menunjukkan bahwa dengan posisi CR naik 52 % sudah bisa menghasilkan kondisi kritis dan mampu mengatasi reaktivitas negatif peracunan xenon maupun suhu. Kata kunci: RDE, HTR, operasi reaktor, batang kendali, reaktivitas, scram ABSTRACT POST REACTOR SCRAM CONTROL RODS POSITION ADJUSTMENT ANALYSIS FOR THE INDONESIAN EXPERIMENTAL POWER REACTOR CONCEPT. Analytical study using PC-based simulator has been carried out on control rods position adjustment of the Indonesian experimental power reactor concept or reaktor daya ekperimental (RDE) in a post reactor scram to continue operation after a certain operation period. Reactivity control of the RDE uses 10 pairs of control rods (CRs), which is based on that applied in the high temperature gas reactor (HTR) 10 MW(t). If an abnormal operating condition occurs, these control rods automatically dropped to the reflector that bring the reactor into a scram and subcritical condition. To continue reactor operation after a period of time, the CRs should be withdrawn to achieve recriticality. Prior to any CRs withdrawal, an analysis of negative reactivity effects of Xenon (poissoning) and fuel temperature coefficient should be done. Simulations using PCTRAN-HTR simulator to determine the optimum CRs positions in achieving reactor criticality for continuation of reactor operation is presented in this paper. The simulations were conducted by varying the reactor power levels at 70%, 85% and 100% of full power, respectively. The reactor operation time was varied at 50s, 10000s, and 20000 s prior to the reactor scram. Adjustment of CRs position should be done to continue reactor operation at those nominal power levels by withdrawing the CRs to the proper positions. The simulation results show that recriticality can be achieverd by whitdrawing the CRs 52% of farther and the negative reactivity from xenon poisoning and temperature could be overcome. Keywords : RDE, HTR, reactor operation, control rod, reactivity, scram.

<p>Rice ragged stunt virus (RRSV) is transmitted by brown planthopper in the persistent manner. This disease in recent years has become a serious problem in Indonesia and some other countries, such as China, Vietnam, Philippines, and Thailand. Disease control is usually conducted by the vector control using insecticides, so often causes an environmental pollution. An alternative control method is using the environmentally friendly of resistant varieties. The purpose of this study was to determine the level of preference of brown planthopper (BPH) to some varieties and rice germplasms, the resistance of several varieties against rice ragged stunt virus (RRSV) disease and its effectiveness as an inoculum source of virus (RRSV). A total of 15 varieties of rice were used in preference test of BPH and resistance test to RRSV. The test for resistance varieties to RRSV was conducted by transmission of 2nd instar of BPH for 3 days of acquisition feeding period, 10 days incubation period and 24 hours inoculation period with population density of 3 BPH/plant. Disease index was calculated and used to determine the level of plant resistance. Varieties that showed resistant, moderately resistant and susceptible responses were selected and were used as a source of inoculum to be transmitted on to TN1 variety susceptible check variety to know the effectiveness of varieties as source of virus inoculum. The results showed that of the 15 varieties tested, Situ Bagendit, Utri Merah, Mentik Wangi, Mahsuri, and Inpari 1 each was less favored by BPH to settle and to multiply. Mentik Wangi, Tetep, Utri Merah, and Swarnalata each showed resistant response to RRSV. Transmission test to susceptible variety (TN1) showed that the variety of Situ Bagendit, Inpari 13, Mentik Wangi, and Tetep each has a fairly low effectiveness as a source of inoculum as indicated by the lower percentage of infection and disease index on the transmited test plants.</p>

Currently, the stem used as grafting material is not in particular source and part of the branch, so it is unclear to determine the success of this activity. This study wanted to examine the success of the interaction between entres upper stem from various branches and the duration of storage. The study used factorial randomized block design with two factors and three replications. The first factor was various types of branch sources (primary branch, secondary branch, tertiary branch). The second factor was the storage time periode (0 day, 2 days, 4 days, 6 days). The results showed that the interaction of the branch source and duration of storage of the upper stem did not affect the number of shoots, shoot length, shoot diameter and total leaf area of durian grafting plants. The source of the stem only affected the diameter of the stem.

Full textAbstract:
We analyse the change trends of the annual and seasonal runoff series of the hydrological station Batang on the headstream of the Yangtze River over the period 1960–2007. The relations between runoff series and precipitation and temperature conditions are investigated, and the influence of the refreezing process of meltwater of the glaciers on the Yangtze River flow is examined with the proposed accumulated temperature deficit (ATD) index. It is found that annual runoff at the Batang station is not stable during the period 1960–2007. From 1960 to 1980, there was a rather strong decrease of 14.4 m3 s−1 year−1 on average in spite of the statistically significant increase in air temperature and rather stable precipitation. It is argued that the annual rate of glacier runoff generation is possibly controlled by the ATD rather than by the direct air temperature. Seasonal analysis indicates that ATD might be of greater influence in autumn and winter in affecting runoff than in spring and summer. The research in this paper may be helpful in understanding how the hydro-climatic conditions affect runoff generation in the cold regions.
