Abstract:
The purpose of this research is to analyze the relationship between the intensity of light hitting the LDR to the resistance and the flame of the light. The research created an automatic lighting system, in which the lighting system was designed to turn on or off lights by light intensity. This research created automatic light controls using LDR light sensor. The LDR light sensor set is used as a switch that turns on or off a light automatically based on the recieved of intensity of light. By using the LDR components, it can design a series of light sensors for such items as outdoor light sensors, sleeping lights, garden lights, road lights that turn on at night and go out during the day automatically. The equipment used of the research were 2 test lamps, and done with 2 lighting sources, a natural source of lighting and an artificial source of lighting. From the research, it showed that the large light intensity affects the light flame by using LDR light sensor. It could be concluded that the greater of the light hitting intensity from the LDR surface was smaller than the value of the resistance and the flickering of the light. In contrast, the less light that affects the LDR, was the greater value of LDR resistance and lighter the light.

Abstract:
Pesawat Atwood merupakan alat yang sering digunakan untuk membuktikan hukum-hukum tentang gerak. Di Laboratorium Fisika Universitas Muhammadiyah Riau, pengukuran pada pesawat Atwood masih dilakukan secara manual dengan menggunakan stopwatch. Penggunaan stopwatch untuk menghitung waktu dianggap tidak optimal karena butuh ketelitian yang akurat yang terkadang mendapatkan hasil yang tidak presisi dan akurat. Pada penelitian ini dirancang sebuah alat yang dapat mengukur percepatan secara otomatis pada pesawat Atwood menggunakan sensor LDR. Alat ini digunakan untuk mengukur percepatan beban jatuh pada jarak 25, 35, dan 40 cm dengan massa beban tambahan 10, 15, dan 20 gram. Dari hasil pengukuran percepatan secara otomatis diperoleh persentase kesalahan rata-rata 3,97%. Hal ini menunjukan bahwa pengukuran percepatan pada pesawat Atwood secara otomatis menggunakan sensor LDR memiliki tingkat keberhasilan 96,03% dibandingkan dengan pengukuran percepatan yang dilakukan secara manual yang hanya memiliki tingkat keberhasilan 89,82%.

Abstract:
Beberapa daerah di Wonogiri memiliki tanah yang mengandung kapur, sementara itu sebagian masyarakat mengonsumsi air yang berasal dari dalam tanah. Pada kegiatan pengabdian kepada masyarakat tahun 2016 ditemukan permasalahan dalam masyarakat di kelurahan Wonogiri yaitu sulitnya mendeteksi adanya kapur dalam air yang mereka konsumsi. Sebagai akibatnya banyak masyarakat yang menderita penyakit dalam yang diakibatkan pengendapan kapur di dalam tubuh mereka seperti penyakit ginjal. Oleh karenanya, tim PPM Fakultas MIPA Universitas Negeri Yogyakarta membangun sistem pendeteksi adanya kapur dalam cairan berbasis Light Emitting Diode (LED) dan Light Dependent Resistor (LDR). LED digunakan untuk menyinari cairan dengan kadar kapur yang berbeda-beda, kemudian LDR akan mendeteksi cahaya LED yang melewati cairan tersebut. Besar kecilnya nilai luaran LDR akan bergantung kadar kapur dalam cairan. Masyarakat sangat antusias dan mulai menggunakan alat ini untuk mendeteksi adanya kapur di air yang mereka konsumsi. Kata kunci: Kesadahan, LDR, LED Workshop On Detector of Water Hardness Based On Light Dependet Resistor In Giritontro Village, Giritontro District, Wonogiri RegencyAbstract Some areas in Wonogiri contain hardness in its soil, while some people consume water that come from the soil. In community service activity in 2016, we found problems in the community in Giritontro, Wonogiri that is the difficulties to detect the hardness in the water that people consume. As a result, many people who suffer from internal diseases caused by the deposition of lime in their bodies such as kidney disease. Therefore, the PPM team of the Faculty of Mathematics and Natural Sciences of Yogyakarta State University built a hardness detection system in liquid based Light Emitting Diode (LED) and Light Dependent Resistor (LDR). LEDs are used to irradiate fluids with different lime levels, then LDR will detect the LED light passing through the liquid. The size of the LDR output value will depend on the lime content in the liquid. People are very enthusiastic and start using this tool to detect the presence of limestone in the water they consume.

Abstract:
Pemborosan dalam penggunaan energi listrik kini tampaknya telah menjadi kebiasaan. Seperti dalam pemakaian lampu jalan yang tetap menyala meski dalam keadaan yang tidak memerlukan penerangan menjadi salah satu kebiasaan tersebut. Dengan kebutuhan akan energi listrik yang terus meningkat, salah satu solusinya yaitu menerapkan sistem otomatis pada penerangan jalan dengan menggunakan sensor Light Dependent Resistor (LDR) dan sensor Passive Infrared Receiver (PIR) yang bertujuan agar pemakaian energi listrik dapat lebih efesien. Dalam jurnal ini penulis ingin membuat rancang bangun penerangan jalan raya berbasis arduino uno. Secara umum prinsip kerja dari alat ini adalah lampu penerangan jalan akan otomatis menyala dengan cahaya redup saat keadaan mulai gelap dengan menggunakan sensor LDR. Lampu juga akan otomatis menyala terang apabila sensor (LDR dan PIR) berhasil mendeteksi sehingga akan menampilkan informasi pada tampilan LCD. Dan jika sensor (LDR dan PIR) tidak mendeteksi apapun lampu jalan akan kembali meredup sehingga dapat menghemat pemakaian energi listrik. Hasil dari rancang bangun ini telah bekerja sesuai dengan yang direncanakan yaitu menghidupkan lampu secara otomatis menggunakan sensor Light Dependent Resistor (LDR) dan sensor Passive Infrared Receiver (PIR). Dan menampilkan informasi pada layar LCD.

Abstract:
Kain merupakan komponen utama dalam pembuatan garmen. Kualitas produk garmen dapat dipengaruhi oleh kualitas kain, maka sebelum melakukan proses produksi garmen perlu dilakukan kegiatan inspeksi kain untuk memeriksa keberadaan cacat pada kain. Pada umumnya inspeksi kain di industri garmen menggunakan sebuah mesin inspeksi yang dioperasikan oleh seorang operator. Akan tetapi operator sebagai seorang manusia akan tetap bisa melakukan kelalaian dalam bekerja. Misalnya terdapat cacat pada permukaan kain yang terlewat untuk diperiksa.Untuk mengurangi jumlah cacat lubang yang terlewat pada kain maka dilakukan penelitian mengenai studi pendeteksi cacat kain menggunakan Hardware berupa Arduino Uno dengan sensor cahaya (LDR) yang dilakukan pada mesin inspeksi kain sehingga dapat mendeteksi cacat lubang pada kain. Arduino adalah pengendali mikro single-board yang bersifat open-source, dirancang untuk memudahkan penggunaan elektronik dalam berbagai bidang. Hardware dalam arduino memiliki prosesor Atmel AVR dan menggunakan software dan bahasa sendiri. Sensor cahaya LDR ini merupakan resistor yang memiliki karakteristik peka terhadap cahaya. LDR akan dapat mendeteksi cahaya yang melewati lubang kain pada jarak tertentu. Cahaya yang melewati lubang dideteksi sebagai perubahan intensitas cahaya sehingga cacat lubang pada kain dapat terdeteksi berdasarkan ukurannya.

Abstract:
The demand for automated home solutions is growing and it has created a market for automated blinds. For now most of these solutions seem to focus on fully opening and closing, either rolling blinds or slat blinds, with different electronic solutions. There doesn’t seem to be many solutions for continuously regulating light inlet based on ambient light. This project examined the possibilities of continuously regulating the amount of natural light let through a window. This was tested by measuring ambient light on one side of the blind with light dependant resistors (LDR’s) and regulating a Venetian blind based on measured light intensity. A feed-forward controller was implemented, programmed on an Arduino Uno board, to control sensors and actuators that regulate the blind. A prototype unit was built on a window-resembling wooden frame to evaluate the performance of the controller. The light sensitivity of LDR’s were sufficient for measuring differences in ambient light in different conditions where an automated blind could be used. The final prototype could be set to adjust light inlet in increments for changes in ambient light, thereby opening up to uses beyond simply closing and opening a light inlet. Future improvements could be to implement a feedback controller (e.g. a PID controller). The controller could be set to a certain reference as preferred ambient lighting in a room, thereby letting the controller adjust the blinds towards that reference value while conditions outside and inside change during the day. This could also be implemented in already existing smart home solutions.
Efterfrågan på automatiserade hemmalöningar är växande och det har skapat en marknad för automatiserade persienner. För nuvarande verkar det de flesta lösningarna fokusera på att helt öppna eller stänga, antingen rullgardiner eller persienner, med olika elektriska lösningar. Det verkar inte finnas många lösningar med kontinuerlig justering av inkommande omgivningsljus. Detta projekt utforskar möjligheterna för kontinuerlig justering av mängden naturligt ljus som släpps igenom ett fönster. Detta gjordes genom att mäta omgivande ljus på ena sidan av persiennen med fotoresistorer och reglera persiennen baserat på den uppmätta ljusintensiteten. Framkopplad styrning implementerades, programmerad på en Arduino Uno, för att styra sensorer och ställdon som reglerar persiennen. En prototypenhet byggdes på en fönsterliknande träram för att utvärdera prestandan av styrenheten.  Ljuskänsligheten i fotoresistorerna var tillräcklig för att mäta skillnader i omgivningsljus för de olika förhållanden där automatiserade persienner skulle kunna användas. Den slutgiltiga prototypen kunde ställas in att justera ljusinsläppet stegvis för skillnader i omgivningsljus, vari nya användningsområden öppnas upp utöver att endast stänga och öppna ett ljusinsläpp.  Framtida förbättringar skulle kunna vara att implementera en återkopplande styrning (t.ex. PID-styrning). Styrenheten skulle kunna ställas in till ett specifikt referensvärde på önskat omgivande ljus i ett rum, vari kontrollern justerar persiennerna för att hålla det önskade referensvärdet medan förhållanden utomhus och inomhus varierar under dagen. Detta skulle även kunna implementeras i redan befintliga smarta lösningar för hemmet.

Abstract:
In today's world, the quality of the crops is of utmost importance. Crops need to be effectively cared for, and steps are needed to ensure their healthy growth. Smart Irrigation is a major topic that has been implemented in certain regions, but the accumulation of various sensors is the key to the effective safety of crops. In the chapter, various sensors are being deployed and used in synchronization. The primary ones included in the system are the water level and moisture sensor, which works in correspondence with the water motor; the proximity (PIR) sensor, which works in accordance with the buzzer and the webcam; and finally, the light-dependent resistor (LDR), which works in relation with the artificial light. The analog data received from the sensors are transmitted to the raspberry-pi and then sent over the network using a Wi-Fi module to Ubidots, where the data will be analyzed, and necessary actions will be taken. The components to be used in the system will guarantee overall prolific, scalable, and ardent implementation.

This paper focused on the energy saving by controlling the light intensity of street light according to the street condition which be measured by the sensor such as light dependent resistor (LDR), passive infrared sensor (PIR), and rain sensor module. LDR detects the natural light intensity which are low, medium, high light intensity. PIR sensor detects the movement of vehicle on the street while the rain sensor module detected the weather at variation phase of water drops (rain) as a safety purpose. In this project, the light intensity of street light is controlled using a functional controller known as the fuzzy logic controller. This type of controller is not based on the model but based on the power detection mechanism. The functional of the system simulates using Proteus Software. The results show the rectangular sinusoidal of the limit of street light intensity.

Abstract:
Abstract Current refrigeration and air conditioning systems are mostly based on the vapor compression cycle, which require electrical energy input. Absorption systems have gained new interest due to the possibility of utilizing waste heat as energy input. In addition, the environmental impact generated by such systems is recognized as much smaller than vapor compression systems. Therefore, this work developed and characterized an absorption refrigeration system with an innovative generator level optical control and variable working fluid mass flow rate, with potential for use in industrial, commercial and residential heating, ventilation, air conditioning, and refrigeration (HVAC & R) systems. The system is hybrid, since it was designed to be fed with heat from the burning of different fuels and/or waste heat sources in complementary fashion. The system consists of: a condenser, an evaporator, two expansion valves, two absorbers, a centrifugal pump, a regenerative heat exchanger, a generator, a rectifier, a generator level optical control system, and two liquid accumulators. The developed level control system consists of 3 light Dependent Resistors (LDR) positioned inside a box built around a transparent level meter, and illuminated internally by a low power light bulb. A frequency inverter and a centrifugal pump allow for the working fluid solution inside the generator to be within a safe range for efficient cooling cycle operation. The system measured refrigeration capacity rate was 2.3 TR, which qualifies as a good performance, since the equipment was originally designed for 1 TR.

Abstract:
Solar trackers are rising in popularity; they benefit a wide range of applications since distributed solar energy generation can reduce electricity costs and support energy independence. In this paper, a simple solar tracking system is introduced. The system is a package unit that can be mounted on any solar panel. The system consists of an electrical motor connected directly to a sliding mass on a linear bearing. The electrical motor is controlled to slide the weight along the shafts in controlled steps. As a result, the photovoltaic panels are rotated automatically under the effect of controlled weight unbalance in fine angle increments to track solar trajectory without the need for traditional complex or costly mechanisms. Two light dependent resistors (LDR) sensors, mounted onto the surface of the solar photovoltaic panel, are exposed to solar irradiance and used to feed signals to a controller. A model of the solar tracking system is developed using ordinary differential equations, and numerically solved by MATLAB/Simulink™. The power consumption and tracking strategy of the proposed tracking system are estimated under realistic operating conditions (e.g. wind and brakes), and the power consumption is compared to the power generated by the photovoltaic panels. Optimum values for the sliding mass are suggested. Two photovoltaic modules are used to calculate the output parameters of the proposed tracking mechanism.
