Abstract

Berkembangnya peralatan kelistrikan yang termasuk kedalam beban non linier banyak digunakan oleh konsumen karena praktis dan mudah dalam hal pengontrolan. Beban non linier yang pada umumnya terbuat dari bahan-bahan semikonduktor dapat menimbulkan distorsi harmonik pada sistem generator sebagai catu daya listrik. Distorsi dapat menimbulkan masalah pada mutu daya listrik yang akhirnya akan menyebabkan berbagai kerugian dan bahkan kerusakan. Generator listrik akan menghasilkan tegangan/arus berbentuk sinusoida dengan frekuensi 50/60Hz dan disuplai ke beban linier atau non linier. Bentuk gelombang tegangan maupun arus keluaran beban linier akan sama dengan gelombang masukan. Tetapi tidak untuk beban non linier, bentuk gelombang tegangan maupun arus keluaran tidak sama dengan gelombang masukan. Suplai daya ke beban non linier yang mempunyai frekuensi kelipatan bilangan ganjil (150Hz, 250 Hz, 350 Hz, dst) dengan bentuk gelombang yang terdistorsi menjadi non sinoida. Pengujian ini dilakukan dengan cara pengukuran menggunakan Powermeter dan akuisisi data dengan IoT yaitu aplikasi Blynk. Dengan diakuisisi menggunakan Blynk, kita dapat memonitoring hasil pengukuran Tegangan,arus, daya aktif, daya reaktif, daya semu, Power factor ,THD% arus maupun THD% tegangan secara realtime. Setelah data diperoleh kemudian dianalisa berdasarkan standar IEEE No.519 tahun 1992. Hasil penelitian menunjukkan pada beban non linier (LHE 8x15W/220V) akan menimbulkan distorsi harmonik yang ditunjukkan dengan kenaikan THD% I sebesar 32,6% diatas standar yang ditetapkan oleh IEEE, sedangan kan THD%V sebesar 1,4% sesuai dengan standar dari IEEE ≤5%. Adanya harmonik terjadi kenaikan arus sebesar 0,689 A dari kondisi arus normal yang menyebabkan kerugian daya pada generator.

Abstract

Electrical energy is energy that can be generated from the conversion of various types of energy, one of which is wind energy. The average wind speed in Indonesia is classified as low speed, only certain areas have moderate to high wind speeds. Low wind speed does not mean that the potential energy contained in it cannot be utilized or converted into electrical energy, it can still be utilized but a generator is needed that matches the characteristics of the wind speed. Therefore, the turbine used is the Savonius type, which can work in low wind speeds. The purpose of this research is to measure output power against wind speed. With experimental methods using an anemometer and measuring voltage, current and output power. From the results of this study, the maximum power generated by the wind power training module is 0.008 Watt with a wind speed of 4.31 m/s and the minimum power generated is 0.001 Watt with a wind speed of 1.17 m/s. In a day, the average wind speed is 2.94 m/s so from the wind speed the wind power training module is able to produce an average power of 0.001 Watt.

Abstract

Sistem pentanahan pada instalasi listrik sangat penting untuk memastikan keamanan pengguna dan mencegah kerusakan peralatan akibat lonjakan arus atau tegangan lebih. Di Balai RW 03 Beji Timur, variasi sifat tanah menyebabkan resistensi tanah yang tinggi sehingga menyebabkan sistem pentanahan tidak berfungsi secara optimal dan berpotensi tidak memenuhi standar keamanan. Penelitian ini bertujuan untuk mengevaluasi efektivitas instalasi sistem pentanahan di Balai RW 03 Beji Timur, Depok, Jawa Barat. Penelitian ini menggunakan metode kuantitatif deskriptif, dengan mengumpulkan data melalui pengamatan langsung dan pengukuran tahanan tanah menggunakan alat pengukur arde. Hasil penelitian menunjukkan bahwa kedalaman penanaman elektroda berpengaruh secara signifikan terhadap tahanan pentanahan. Pada kedalaman 5 meter, resistensi masih tinggi dan tidak memenuhi standar PUIL 2011 yaitu ≤ 5 °C. Dengan menghubungkan dua elektroda secara paralel, nilai resistansi berhasil diturunkan ke kisaran 2,44 - 2,82 °C, sehingga memenuhi standar keamanan. Dengan demikian, sistem pentanahan elektroda terhubung paralel pada kedalaman 5 meter memberikan perlindungan yang lebih baik untuk instalasi listrik di Balai RW 03 Beji Timur.

Abstract

ABSTRACTPalm oil mills will produce liquid waste which is often called POME (Palm Oil Mill Effluent). This waste if not handled properly will disrupt the environment, even though POME stores a large potential of energy that can be used to support energy needs. With special processing, POME can produce biogas. Then biogas can be used as fuel for generators and ultimately can produce electricity. The process of processing from POME to biogas can be formed in a Biogas Power Plant (PLTBg). The amount of electrical energy that can be generated depends on the amount of biogas formed, while the amount of biogas that will be obtained generally depends on the volume of POME and the content of COD (Chemical Oxigen Demand) in POME. In the sample factory, one year of data has been taken. From the results of the analysis of the prediction of the calculation of electricity energy in palm oil mills through the construction of Biogas Power Plants, the average predicted monthly biogas that can be obtained based on data is 279023,248 Nm3CH4/month and maximum biogas that can be obtained based on the maximum processing of coconut mills oil palm is 506153.34 Nm3CH4/month. The average predictable generating capacity based on data is 1.3 MWe and the maximum capacity that can be built should be around 2.37 MWe.Keywords : Palm Oil Waste, POME, Biogas, Renewable Energy, MetaneABSTRAKPabrik kelapa sawit akan menghasilkan limbah cair yang sering disebut POME (Palm Oil Mill Effluent). Limbah ini jika tidak ditangani dengan baik akan mengganggu lingkungan, padahal POME menyimpan potensi energi yang besar yang dapat dipergunakan untuk mendukung kebutuhan energi. Dengan proses pengolahan khusus, POME dapat menghasilkan biogas. Biogas kemudian dapat dimanfaatkan sebagai bahan bakar untuk genset biogas yang akhirnya dapat menghasilkan listrik. Proses pengolahan dari POME menjadi biogas dapat dibentuk dalam suatu Pembangkit Listrik Tenaga Biogas (PLTBg). Jumlah energi listrik yang dapat dihasilkan bergantung pada jumlah biogas yang terbentuk, sedangkan jumlah biogas yang akan diperoleh pada umumnya bergantung dari volume POME dan kandungan COD (Chemical Oxigen Demand) pada POME. Pada pabrik sampel, data satu tahun telah diambil. Dari hasil analisis prediksi perhitungan pendapatan energi listrik pada pabrik kelapa sawit melalui pembangunan PLTBg, rata-rata prediksi tiap bulan biogas yang dapat diperoleh berdasarkan data adalah 279023.248 Nm3CH4/bulan dan maksimum biogas yang dapat diperoleh berdasarkan maksimum pengolahan pabrik kelapa sawit adalah 506153.34 Nm3CH4/bulan. Rata-rata kapasitas pembangkit yang dapat diprediksi berdasarkan data adalah 1.3 MWe dan maksimum kapasitas yang dapat dibangun sebaiknya sekitar 2.37 MWe.Kata kunci : Limbah, POME, Biogas, Energi Baru dan Terbarukan, Metana

Abstract

Hydropower plants have limitations in scalability and location, as they require large water flows and complex infrastructure. One solution to overcome these drawbacks is portable hydroelectric power plants, which are more flexible and adaptable to variations in water level. Portable geothermal power plants allow the regulation of water fall height to optimise their performance, especially in remote areas that are not reached by conventional power grids. This research aims to develop the performance of portable geothermal power plants by utilising variations in water level to analyse the performance of the effect of water fall height on the performance of portable geothermal power plants with crossflow turbines. This research uses an experimental method, which involves collecting and analysing data from the height of (variation 1) and (variation 2) to determine the performance of the Pico Hydro Power Plant (PLTPh). The research was conducted at Mahogany Lake, University of Indonesia. The data collected includes measurements of voltage, current, power, and rotation speed of the turbine and generator at different altitude variations to determine the effect of water fall height on the performance of PLTPh with crossflow turbines. The results showed that the height of the water fall can affect the performance of the Pico Hydro Power Plant (PLTPh). At the height (variation 1), the power and output voltage generated are higher than the height (variation 2). In addition, the output voltage is also greater when the generator is operating without load. This difference shows that variations in altitude, flow speed and water discharge entering the turbine cross section greatly affect the rotation of the generator and the amount of electrical power generated by the PLTPh.

Abstract

This research addresses the lack of an accurate and efficient monitoring system for renewable energy utilization in Tidung Island. Despite its high solar and wind energy potential, the absence of real-time environmental data hinders optimal energy management. Existing IoT-based monitoring systems are costly and complex, making them unsuitable for remote areas. This research integrates Blynk IoT and Google Sheets database for real-time, cost-effective, and easily accessible data storage. This system enables real-time data acquisition to support efficient energy management and environmental monitoring in remote areas. Testing results show that the Telkomsel 4G modem provides a more stable connection with lower latency and minimal packet loss. Temperature remains between 25–30°C, while humidity fluctuates up to 100% at night. Wind speed is classified as low to moderate (1.0–6.1 m/s), and CO₂ levels range from 400–600 PPM, remaining within safe limits. These findings suggest the need for improved energy storage, system resilience against environmental changes, and adaptive energy management strategies for optimal hybrid renewable energy utilization.

Abstract

Setaman village that located in cipayung Depok have a home made product business fried onion. This home made product business do with the mother in this village . Each day this unit business can produced 10 kg of fried onion, wich is it can be last until 2-3 months. This home made product business is still carried out manually, starting from the onion peeling process to the onion frying process, so peeling and slicing 10 kg of onions takes 4 to 5 hours. Community Based Science and Technology Application Program (PPIBM) The Electrical Engineering Study Program will implement an automatic onion peeler and slicer sourced from solar panel with a capacity of 550 Wp. In this way, it can reduce the production time for fried onions, as proven by data showing that peeling 3 kg of onions takes 31 minutes and slicing 3 kg of onions only takes 14 minutes. Apart from that, with a solar panel installed with a capacity of 500 Wp with an average daily peak sun hours, 3 hours a day, the energy that can be produced is 1500 watthours. With 1500 watthours of energy, it can fulfill the energy needs of an onion peeler with a capacity of 350 watts for 3 hours. So it is hoped that the community can further increase the production of home made product business fried onion and can also create energy security in the community.
