Abstract

Batu bara merupakan bahan bakar yang tidak dapat diperbarui dan masih mendominasi peran sebagai bahan bakar utama Pembangkit Listrik di Indonesia. Sumber energi yang dapat diperbarui seperti matahari mulai dikembangkan sebagai alternatif. PLTS merupakan sistem yang mampu mengkonversi energi radiasi cahaya matahari menjadi listrik menggunakan modul semikonduktor fotovoltaik. Gedung Teknik Politeknik Negeri Jember memiliki PLTS di atapnya yang terdiri dari 4 kWp PLTS off-grid dan 6 kWp PLTS on-grid. Namun, hanya sistem off-grid sebesar 4 kWp saja yang sudah dioperasikan. Pada penelitian ini dilakukan studi evaluasi pada PLTS off-grid terkait berdasarkan Panduan Studi Kelayakan PLTS dan IEC 61724. Pengujian dilakukan selama 3 hari mulai pukul 09.00 – 14.30 dengan interval 30 menit menggunakan 2 lampu halogen dengan total daya 800 W. Berdasarkan penelitian yang telah dilakukan, PLTS memiliki nilai efisiensi PV 43 %, inverter 92 %, SCC 95 %, dan rasio performansi 44%. Selama proses pengujian tidak didapati kendala yang fatal dan kondisi fisik komponen secara keseluruhan baik. Optimasi yang dapat dilakukan adalah maintenance seperti cleaning secara berkala, penambahan perangkat monitoring seperti pyranometer yang terintegrasi dengan sistem PLTS untuk memudahkan pemantauan sistem. Untuk meningkatkan efisiensi modul surya, penambahan alat pembuang panas pada modul atau sistem pendinginan dapat dilakukan.

Abstract

Discontinuity in welds is one of the causes of the quality of a connection in the material decreases function. Undamaged test with radiographic method is one of the tests to see the quality of a weld. The test results are radiograph images and evaluated by a radiographer. So this research is designed by optimizing a system to help the work of a radiography expert in identifying discontinuities by utilizing the Matlab Application. On this system uses the method of characteristic extraction and classification of neural networks (AAN). The system uses a characteristic extraction method with geometric invariant moment (GIM) algorithms and a gray level co-occurenece matrix (GLCM) as identification values used in the classification process. The calcification process uses a backpropagation-type multilayer Artificial Neural Network. The types of discontinuities used as data in this system are incompleted of penetration, crack, wormhole, and distributed porosity using a total of 800 datasets of radiograph imagery data. This data sharing is organized using k fold cross validation. The study conducted 15 experiments in system testing to prove the truth in identifying. The results of the experiment resulted in the highest average performance score reaching 93.33%

Abstract

Indonesia is a maritime country that has enormous potential in marine products. One of the marine products which is the highest export commodity is shrimp. Lingkungan Pakem, Karangrejo Village, Banyuwangi Regency is a partner location that is one of the national shrimp producing centers. Partners cultivate vaname shrimp with an intensive system as a producer of oxygen bubbles. The application of an intensive system causes problems, namely the amount of electricity costs and the uneven flow of water flow so that oxygen levels are not optimal. Based on these problems, the application of venturi finebubble portable buoy technology based on solar cells and IoT aims to increase the efficiency of the production of vannamei shrimp produced. The stages of technology application to partners consist of observation, planning, manufacture, assembly, and evaluation. The implementation of this technology can reduce electricity bills from operational costs in one harvest period (2 months) which was initially IDR 3,000,000.00 to IDR 2,000,000.00 and the average mortality rate of shrimp from 3000 individuals is equivalent to IDR 1,100,000.00 to 1560 individuals which is equivalent to IDR 572,000.00. Thus, the savings achieved are 37% or IDR 1,528,000.00 per harvest.

Artinya diperoleh volume minyak yang masih tertinggal diseparator berkisar antara 18 – 20 mL. Bila waktu pemisahan diperpanjang hingga 12 jam maka akan diperoleh minyak yang tertinggal berkisar 2-5 mL. Manufacture and Performance Test of Laboratory Scale Essential Oil Separator Equipment with a Capacity of 25 LitersAbstract. The separator is a means of separating essential oils from distilled water in the essential oil refining process. The design of the separator is adjusted to the specific gravity of the essential oil to be processed. The purpose of this study was to test the performance of a laboratory scale essential oil separator with a capacity of 25 liters by gravity with a distillate rate of 4.0 – 4.5 L/hour. The results of the functional test show that the separator components function properly according to their functions, both individually and in machine assembly. The separation process is carried out by flowing a mixture of oil and water into the separator with a discharge of 4.0 – 4.5 L/hour using an aquarium pump. The yield results obtained values ranging from 0.82 to 0.88% in the volume of oil added from 100 to 150 mL. This means that the volume of oil that is still left in the separator ranges from 18 to 20 mL. If the separation time is extended to 12 hours, the remaining oil will be in the range of 2-5 mL.

Abstract

Sunlight as one of the abundant renewable energy sources and can be used as a source of electrical energy, especially in Indonesia which is a tropical country. This community service activity aims to provide solutions to problems experienced by partners, SMPN 04 Tempurejo. The problem experienced by partners is that schools still do not have access to electricity. Methods of implementing community service activities include surveys and observations, socialization, installation preparation, implementation, training and mentoring and evaluation. The results of this community service have run well because all activities carried out are in accordance with the scheduled timeline. The implementation of a 150 Wp solar panel-based electrical energy source at SMPN 04 Tempurejo has succeeded in providing solutions to the problems faced by partners, namely the existence of lighting and new learning media facilities, in the form of mini PCs and increasing students' understanding of renewable energy and its use as an alternative energy source and the use and maintenance of solar panel systems.

Abstract

Renewable energy that is now widely loved is solar energy, which can be converted into electrical energy with the help of solar panels. Solar panels are made of semiconductor silicon which absorbs photons from the sun's energy. However, the sun does not only produce photons which can be converted into electrical energy, but there is also heat energy which can increase the temperature of the solar panels which can reduce the performance of the solar panels. Therefor researchers conducted research to reduce the temperature of solar panels by using the monocrystalline solar panel cooling method using mineral oil with the immersion cooling technique. However, from the experimental data in the field, it was found that the results were not good where solar panels without cooling were more than solar panels with cooling. The anova analysis test which was continued with the Tukey method confirmed that the voltage and current of the uncooled solar panels were superior, namely 4.48 V and 0.94 A. Solar panels with a 3cm cooling liquid variation produced a power of 3.93 W while non-liquid solar panels The cooler produces a power of 4.81 W, so research on cooling solar panels using liquid mineral oil with immersion cooling techniques has not succeeded in increasing the performance of solar panels and cannot be applied to PLTS.
