Desulphurization of Ferronickel in the converters with oxygen is the most complex part of the technological process in the Drenas foundry. Sulphur in the ferronickel melting is mostly in the form of FeS, with a melting temperature of 1195oC, and it has tendency to dissolve indefinitely in liquid iron. Our objective is to determine the sulphur removal coefficient, as a key indicator of the desulphurization efficiency in the converter, by measuring the activity and concentration of sulphur and other elements in liquid Fe and melting. Determination of this coefficient is done according to the analytical method, while comparing the current process parameters with those of the new desulfurization methods, other indicators of the refining process are determined. The refining process and the effective conduct of the study depend on the XRD analysis database of metal and slag, and as well of the technological refining process analysis data. Research has shown that desulfurization efficiency is a function of the sulphur removal coefficient, respectively; metal composition, slag, oxygen activity, CaO/SiO2 ratio, sulphide capacity, fluidity, surface pressure, etc.). In addition to this coefficient, other indicators of refining process optimization are defined.

Reference materials for water microbiology were prepared by spray-drying milk, artificially contaminated with a known test strain. The resulting highly contaminated milk powder was mixed with sterile milk powder to a contamination level of 2000-3000 cfu/g. Gelatin capsules were filled with the mixture (0.2 g/capsule) to produce the reference materials. Test strains used were: WR1 Escherichia coli, WR3 Enterobacter cloacae, WR63 Enterococcus faecium and WR51 Staphylococcus spec. Optimalization of the mixing procedure and aging of the highly contaminated milk powder resulted in relatively homogeneous and stable reference materials. Short-time challenge tests at “high” temperatures (30 and 37 °C) may be predictive for long-term stability at “low” temperatures (4-6 °C). Reference materials with strain WR3 were stable for one week at 30 °C and for at least 6 months at 4-6 °C. Possible applications of the reference materials are: quality control of routine measurements, comparison of the efficiency of different culturing methods and as a standardized sample in collaborative studies.

The aim of this research was the elaboration of the technological parameters of biological digestion and biogas production from poultry feather produced in large quantities by slaughterhouses. Feather protein was digested by Bacillus licheniformis, keratin desintegrator bacteria. Investigations focused on the optimalization of parameters influencing poultry feather biodegradation. The optimal range of pH, temperature, feather size and bacillus:feather ratio were determined in the experiments as well as the analysis of relationship between the examined parameters. In order to be able to track the dinamics of the biodegradation, we determined the extintion level of the liquid phase of the biodegraded material in the different experimental treatments. The results showed that the rate of hydrolisis was significantly higher in the treatments with bacteria than in the treatments without it. The most extensive digestion were observed in case of 1:3 feather:water ratio. The highest intensity of feather digestion were detected in the treatment with 1% microbe ratio.

In the years 2001–2003 in field trials we studied the effects of the conditions of year, fore-crops (winter wheat, sugarbeet, grain maize) and optimalization of the nutritional status on the yield and crude protein content in the grain of spring barley. From the analysis of the plants we can see that dry matter production and nutrient concentration in the plants were influenced by the conditions of the year and the fore-crop. After sugar beet, the growth of the dry matter was intensive and the concentrations of nutrients per one plant were higher as early as in the initial stages of vegetation. The yields in the years 2001 and 2002 corresponded with these results while the highest yields were seen after the sugar beet. Due to the extreme lack of precipitation, the best fore-crop in 2003 was maize. While the dose of 50 kg N/ha increased the yields after maize, after wheat it reduced the yields and increased the crude protein content in the grain.

<p>ABSTRACT</p><p><br />Mobilization of Agricultural Machines Based on Crop Calender for Rice Cultivation in Grobogan District, Central Java. Agricultural machines for rice production in Central Java especially Grobogan District are already intensively developed, but their utilization is still low. Optimalization use of those agricultural machines is needed to improve their performances. This research aimed: (i) To arrange mobilization concept of agricultural<br />machines in order to optimize their use for rice cultivation in Grobogan District, and (ii) To analyze the deficit and working capacity of those agricultural machines after optimalization use through their mobilization. This research was focused on hand tractors and power threshers only, and was conducted in Grobogan District, in 2013. Data on lowland area and population of hand tractor and power thresher were collected from agricultural office of Grobogan District and its Sub-districts, meanwhile data dealing with agricultural machine’s performances were collected through interview with agricultural machines owner and UPJA using well structured questioners. The collected data were arranged in the form of table and map, and then analyzed using requirement and mobilization analyses. The results showed that through mobilization scenario of 20% available agricultural machines among sub-district with four different planting times in Grobogan District could improve the machine’s performance and could reduce their deficit. By mobilizing those agricultural machines for rice cultivation in Grobogan District, their deficit could be reduced up to >50%, meanwhile, working capacity of those machines could be increased from < 30 ha/year/unit before mobilization become 35,5 ha/year/unit after mobilization.</p><p><em>Keywords: optimalization, mobilization, agricultural machines, crop calendar, rice</em> </p><p>ABSTRAK</p><p><br />Alsintan untuk budidaya padi di Jawa Tengah khususnya di Kabupaten Grobogan sudah berkembang namun pemanfaatannya masih rendah.

The objectives of this research were the optimalization of production and reproduction of buffalo heifers through improving feed quality based on rice straw. Twelve heifer buffaloes with body weight of 243 – 350 kg were kept in individual cages and grouped to four. Each groups were randomized to receive three treatments of A, B and C according to Randomized Completely Block Design (RCBD). A was buffalo fed only rice straw. B was buffalo fed rice straw supplemented with concentrate with a dry matter ratio of 70:30. C was similar to B but the rice straw was ammoniated using urea of 4% ensiled with 8% of cassava pulp. In-Vitro test was conducted to measure rumen fermentation product. The results showed the highest of DM and OM digestibility was achieved at C treatment, while the lowest was found at A treatment. Rumen fermentation produsts and its efficiency were the highest in C treatment. In-vivo result showed that ADG of C was higher than that of B and A. Reproductive performance characterized by frequency oestrus for 123 days were an average of 2.5, 2.8 and 4.5 times for A, B and C, respectively. The highest blood metabolite of glucose, urea and erytrocyt was found at C but the leucocyt was lowest compared to A and B. Urea treated rice straw ensiled with cassava pulp and supplemented with concentrate can improve production and reproduction performance of heifer buffaloes.

Kesambi (Schleichera oleosa L.) is one of ligneous tree that is abundantly found in Timor island, East Nusa Tenggara Province of Indonesia. Kesambi is known as an important component in local smoked meat home industry. Kesambi is also a promising natural source for the production of biodiesel. Application of three lipolytic fungi that is isolated from kesambi seeds and the use kesambi seeds flour as medium for indigenous lipase synthesis (Aspergillus niger M1407 lipase) by Solid-State Fermentation (SSF) showed good result for lipase and biodiesel industry development. This study aimed to characterize biodiesel synthesis using indigenous lipase from kesambi seeds. Experiments were carried out through five stages namely: oil extraction from kesambi seeds, purification of kesambi oil (degumming), extraction of A. niger M1407 lipase, trans-esterification and esterification activity of A. niger M1407 lipase assay and characterization of biodiesel. Biodiesel synthesis using A. niger M1407 lipase through esterification reaction produced biodiesel with an average acid number of 0.33 and 0.40 mg/g, water content 9.52 % and 10.47 % and density 0.7 g/mL. Biodiesel obtained from kesambi oil has lower acid numbers and densities but higher water content compared to Indonesian National Standard (SNI) value. Optimalization of the biodiesel kesambi oil synthesis could be done through adjusting ethanol and kesambi oil ratio and also by reducing water as a by-product of esterification reaction

The optimalization of raw materials supply is intended to meet the needs of raw materials for the process of the production process the future; the activity of controlling raw materials manages the implementation of necessary supply in accordance with the required amount and minimal cost, which includes the problem of purchasing raw materials, storing and maintaining materials, controlling the output of the material when materials are needed and maintaining the optimal supply amount. The raw material supply control can be analyzed using the EOQ method as one of the choices in comparing the implemented company policies. This research was conducted at Agronas Gizi Food. The analysis technique used is by comparing the results of company policy calculation and the EOQ method. The calculation of company policy includes the cost of ordering (S) with the results of Rp. 183,800 / order, supply costs (H) with a result of Rp.859 / Kg, total inventory costs (TIC) that must be spent Rp.5,689,560, the frequency of purchase 30 times, with an average purchase of 1500 kg / year while the calculation method EOQ includes economical purchases (Q*) with results of 4198 kg, frequency of purchases (F) with the result 10 times a year, total inventory costs (TIC) with the result of Rp.3,605,795, safety stock Rp.3,605,795, and ROP 234 Kg. Based on the analysis technique on raw material for potato chips in Agronas Gizi Food, it can be concluded that it is not optimal because the calculation the results of company policies are greater than the EOQ method.

Farmer often undergo of constraint in determining optimal price so that the farmer often undergo of loss, it is because the price of the commodity sold is less than the cost of production in the management of agroforestry systems. Determination Optimalization price of commodity agroforestry expected able to improve income of farmer agroforestry maximally. Objectives of this Research is to analyze the optimization of agrocommodity prices to increase farmers' income. This research used Rudihilmanto Pricing method. Result of this research points out proportion plants: coffee (98.30%), clove (0.45%), melinjo (0.23%), and petai (1.02%) in farmers' fields have optimal price ≥ real price so that this condition has risks and disadvantages for farmers now, but if the proportion is changed as coffee (31.77%), clove (28.79%), melinjo (19.06%), petai (20.37%), therefore optimal price is lower than the real price and it is possible to provide the maximum gain to the farmers of Rp.122,056,970.00 per annum in one hectare. Petani sering mengalami kendala dalam menentukan harga optimal sehingga petani sering mengalami kerugian, hal ini karena harga komoditi yang dipasarkan lebih kecil daripada biaya produksi dalam pengelolaan sistem agroforestri. Penentuan optimalisasi harga pada komoditi agroforestri diharapkan mampu meningkatkan pendapatan petani pengelola agroforestri secara maksimal. Tujuan penelitian ini adalah untuk menganalisis optimalisasi harga komoditi agroforestri untuk meningkatkan pendapatan petani. Penelitian ini menggunakan metode Harga Rudihilmanto. Hasil penelitian menunjukkan proporsi tanaman kopi (98,30%), cengkeh (0,45%), melinjo (0,23%), dan petai (1,02%) di lahan petani memiliki harga optimal ≥ harga riil sehingga kondisi ini memiliki risiko dan kerugian bagi petani, tetapi apabila proporsi diubah menjadi tanaman kopi (31,77%), cengkeh (28,79%), melinjo (19,06%), petai (20,37%) maka harga optimal ≤ harga riil dan dimungkinkan mampu memberikan keuntungan yang maksimal bagi petani sebesar Rp.122.056.970,00 tiap tahun dalam satu hektar.

ABSTRAKPenelitian ini bertujuan untuk mengevaluasi optimalisasi penggunaan level sabun kalsium yang berbeda dalam ransum secara in vitro terhadap karakteristik fermentasi, populasi mikroba dan kecernaan nutrien ransum, menggunakan sumber inokulum cairan rumen sapi Bali. Penelitian dilaksanakan menggunakan rancangan acak kelompok dengan 4 jenis perlakuan dalam 3 ulangan. Ransum penelitian terdiri atas : R1, 40% rumput lapang (RL) + 60% konsentrat (K), R2 (40% RL + 60% K, mengandungn 2.5% SCa-kedelai), R3 (40% RL + 60% K, mengandung 5% SCa-kedelai), R4 (40% RL + 60% K, mengandung 7.5% SCa-kedelai). Variabel yang diukur terdiri atas karakteristik fermentasi in vitro (pH, N-NH3, produksi total volatile fatty acids), populasi mikroorganisme (total bakteri dan total protozoa), dan kecernaan nutrien (kecernaan bahan kering dan kecernaan bahan organik). Data dianalisis menggunakan analysis of varians (ANOVA) dan perbedaan antara perlakuan diuji dengan Duncan’s Multiple Range Test. Hasil penelitian menunjukkan, penambahan SCa-kedelai pada level yang berbeda dalam konsentrat tidak mempengaruhi pH, konsentrasi amonia, populasi mikroba, kecernaan bahan kering dan kecernaan bahan organik fermentasi tetapi berpengaruh sangat nyata (P<0.002) terhadap produksi total VFA. Produksi total VFA tertinggi diperoleh pada ransum perlakuan R4 (konsentrat yang mengandung 7.5% SCa-kedelai). Produksi total VFA tertinggi diperoleh pada perlakuan R4 dan produksi total VFA paling rendah terjadi pada perlakuan ransum R1 (kontrol). Produksi total VFA ransum R1 dan R2 dan ransum R2 dan R3 tidak berbeda nyata namun produksi total VFA ransum R3 lebih tinggi dibanding ransum kontrol. Penambahan SCa-kedelai dalam konsentrat menghasilkan produksi total VFA tetinggi namun mulai menekan populasi total bakteri. Mempertimbangkan hasil peubah fermentasi dan populasi mikroba serta biaya pembuatan produk sabun kalsium, SCa-kedelai pada level 5% merupakan level penggunaan SCa-kedelai yang terbaik dalam ransum.Kata kunci: sabun kalsium, fermentasi, in vitro, kecernaanABSTRACTThe study to evaluate the optimalization the different level of soybean oil calcium soap (CaS-soybean) in ration on in vitro fermentation using Bali cattle rumen fluid. The experiment was arranged in a complete randomized block design with 4 different ration treatments and 3 replicates. Ration treatments were R1: 40% native grass (NG) + 60% concentrate (C), R2 : 40% NG + 60% C, supplemented with 2.5% soybean oil calcium soap (CaS-soybean), and R3 (40% NG + 60% C, supplemented with 5.0% CaS-soybean and R4 (40% NG + 60% C, supplemented with 7.5% CaS-soybean). Variables measured were fermentation characteristics (pH, NH3-N, total volatile fatty acids), microbial population (total bacteria and total protozoa), and nutrient digestibility (dry matter and organic matter digestibility). Data were analyzed using analysis of variance (ANOVA) and the differences between treatments means were examined by Duncan Multiple Range Test. Results of the study showed that the four different level of CaS-soybean in ration did not have any significant effect (P>0,05) on pH, NH3-N, total bacteria, total protozoa, dry matter and organic matter digestibility. The treatments significantly increased (P<0.05) the production of total volatile fatty acids. The highest production of total VFA was obtained from ration R4 (concentrate containing 7.5% CaS-soybean) and the lowest was obtained from treatment R1 (control). There were no significant differences between R1 and R2, and between R2 and R3 on the total VFA production. However, the total productions of VFA in ration R3 were higher than that of the control ration. The addition of CaS-soybean in the concentrate had increased the total production of VFA, but at the same time, it began pressing the total population of bacteria. Considering the results of the fermentation variables and microbial population as well as the cost of making calcium soap products, CaS-soybean at 5% level was selected as the best level of CaS-soybean in ration.Keywords : calcium soap, fermentation, in vitro, digestibility

Perikanan merupakan salah satu sumber pendapatan nasional dan lapangan pekerjaan bagimasyarakat Indonesia. Peran penting sektor tersebut pada saat ini belum diiringi dengan pengoptimalanpemanfaatan potensi yang ada. Salah satu upaya pemerintah adalah melalui Program NasionalPemberdayaan Masyarakat Mandiri Kelautan dan Perikanan (PNPM Mandiri KP) sebagai upaya untukmengentaskan kemiskinan yang lebih dari 60 persen berada di wilayah pesisir. Anggaran yang tidaksedikit dikucurkan untuk program tersebut. Penelitian ini bertujuan untuk mengidentifikasi kinerjaoutcome dan kinerja manfaat dan dampak dari PNPM Mandiri KP pada berbagai usaha perikanan.Penelitian dilakukan pada bulan Januari – Mei 2013. Metode pengolahan data yang digunakan padapenelitian ini adalah metode deskriptif. Hasil penelitian menunjukkan bahwa kinerja outcome PNPMMandiri KP pada kelompok perikanan tangkap, pembudidaya ikan, pengolah/pemasar, dan petambakgaram berturut-turut adalah: 1) 19 persen, 37 persen, 27 persen dan 31 persen untuk peningkatanproduksi dan produktivitas; dan 2) 54 persen, 33 persen, 57 persen dan 31 persen untuk peningkatanpendapatan. Kinerja manfaat dan dampak seperti tercantum dalam petunjuk pelaksanaan PNPM MandiriKP yaitu perkembangan usaha, berfungsinya kelompok sebagai lembaga ekonomi dan berkurangnyakemiskinan di lokasi program belum terindikasi secara eksplisit karena terkendala sistem pendataanyang tidak mencakup pengukuran kinerja tersebut. Rekomendasi yang diusulkan sebagai perbaikankebijakan di masa mendatang diantaranya adalah: 1) program harus diarahkan pada pembinaandalam aspek kewirausahaan, manajemen usaha dan manajemen keuangan; 2) masyarakat yang tidakmenerima bantuan dilibatkan sebagai bagian dari skenario program; dan 3) menyertakan programprogrampembinaan dan pendampingan yang diarahkan pada penyiapan penerima program untukmemanfaatkan kenaikan pendapatannya untuk digunakan sebagai fasilitas yang dapat meningkatkanproduksi dan pendapatan lebih besar lagi pada saat mereka tidak lagi mendapatkan bantuan.Title: Evaluation of Marine And Fisheries National Program on PeopleEmpowerement in Support to Fishery IndustrializationFisheries represents a notable source of income generation and job creation for Indonesia.The important role of fisheries has so far not been followed by optimalization of the existing potentials.Recognizing this, the government is currently carried out a program called the Marine and FisheriesMandiri National Program on People Empowerment (PNPM Mandiri KP), which represents a relevanteffort to alleviate poverty, wherein 60% of which occurs in the coastal areas. A significant amount ofbudget has been allocated to this program. This objective of this research is to identify the benefit, impactand outcome performance of the program.

The disertation is to prove that there was a wrong government policy of establishing the Provincial Minimum Wage reffering to the living cost for single. Because of such reason, the wage paid to labour is always insufficient to meet the living cost for labour and his family. The minimum wage should cover the operational cost of labour, so they can work fully during one month. The data of the minimum wage applied in in Pulau Gadung Estate, Jakarta (JIEP) showed that the wage paid to workers were only able to survive. If the policy is continued to be kept, the labour can not improve their living quality, and event the labour will be poor forever.This disertation is an alternative solution to overcome low wage happened in Indonesia. The system found will result the optimalization of labour income as their right must be gained from the company, and further effect to the company, the company will gain more profit, and event the company will develop its business optimally. Wage labour system will combine shirkah-inanwaal-ijarah so it will have a form of sharing any profit among labour, management power and stake holder. Besides, the labour will get wage proper basic wages including basic salary and benefit.The disertation refuses the views: firstly, employers and the Indonesia government bureaucracy have created the labour as a part of production, effientcy and attractor for investation with low wages. Secondly, Jack Stiber says that workers are human resource belong to companies like other resources such as machine, material, money and method. As a result, workers must be ready for ending their works anytime. For management, the workers can be conside, as things like other sources. This ways resulted outsourcing method of employing labour. Thirdly, a view of Abdurahman al-Maliki, said that the policy of wage is based on estimation of experts in manpower market stock exchange.This dissertation has supported related to the Naqvi’s opinion about the distribution of income should be separated from the concentration of the economic power dominated by certain people, but the economic power must orientate to maximize the total welfare. The dissertation also improve the opinion of Joseph Qardawi starting that wages of labour is given on basis of value of his work and it is not just enough to eat and drink as a replacement for the lost power, but the wage must also consider the workers’ participation as a profit generator. Mustajir must pay full wages ajir event though the workers are willing to accept under proper wage. According to the opinion of Banisadr, Islam rejects all concepts related to the application where the human beings or some of the people receive and get a bigger wage than the others who out of their responsibility. Abdul Jalil combine the wage system between the principal wage with the incentive (gainsharing) with the term combination called as shirkah inanwa al-ijarah which is still normative. Thus, the three opinions above cannot be applied in the waging system in increasingly complex companies.This dissertation is a case study observing labour wage system in Jakarta Industrial Estate Pulogadung in view of business men, labour and goverment. The primary data was randomly gained through quesionares and deep interview comparing with constitution nomor 13, 2003 and Islamic wage concept. The Interpretation of Islamic wage concept uses fenomenology method which is a research method that mixed a subjective interpretation in observation object. The involvement of researcher in the field observing the object becomes standard pattern.

Aim of the present investigations was the optimalization of the production of the annual cultivar `Napfény' of Verlxiscum phlomoides L. Quantitative data on morphology (growth, leaf and flower size, branching) yield and content of active materials (mucilages, flavonoids) were studied at six sowing times.
We established, that sowing time may be one basic factor in the production of the annual variety. The major yield was obtained by sowing either late autumn (end of October) or early spring (middle March). At these plots the fresh mass of the flowers was 257-288 g/plant, the drug mass 28-29 g/plant, by 45-70% more than that of the mean of other treatments.
It was established, that under optimal cultivation conditions the annual form of mullein may reach higher individual yields than the plants of the indigenous wild growing population.

Kesambi (Schleichera oleosa L.) is one of ligneous tree that is abundantly found in Timor island, East Nusa Tenggara Province of Indonesia. Kesambi is known as an important component in local smoked meat home industry. Kesambi is also a promising natural source for the production of biodiesel. Application of three lipolytic fungi that is isolated from kesambi seeds and the use kesambi seeds flour as medium for indigenous lipase synthesis (Aspergillus niger M1407 lipase) by Solid-State Fermentation (SSF) showed good result for lipase and biodiesel industry development. This study aimed to characterize biodiesel synthesis using indigenous lipase from kesambi seeds. Experiments were carried out through five stages namely: oil extraction from kesambi seeds, purification of kesambi oil (degumming), extraction of A. niger M1407 lipase, trans-esterification and esterification activity of A. niger M1407 lipase assay and characterization of biodiesel. Biodiesel synthesis using A. niger M1407 lipase through esterification reaction produced biodiesel with an average acid number of 0.33 and 0.40 mg/g, water content 9.52 % and 10.47 % and density 0.7 g/mL. Biodiesel obtained from kesambi oil has lower acid numbers and densities but higher water content compared to Indonesian National Standard (SNI) value. Optimalization of the biodiesel kesambi oil synthesis could be done through adjusting ethanol and kesambi oil ratio and also by reducing water as a by-product of esterification reaction.
