Abstract

The increasing demand for electrical energy, driven by population growth and industrial development, necessitates efficient and sustainable power distribution systems. Transformers, essential components of these systems, typically use mineral oil for insulation and cooling, despite its environmental drawbacks, such as high carbon emissions and non-biodegradability. In response, natural ester oils have emerged as eco-friendly alternatives. This study aimed to compare the dielectric breakdown voltage characteristics of mineral oil (Diala B) and natural ester oil (FR3) in transformer applications. The testing followed the IEC 60156 standard, focusing on transformers operating at 20 kV, with a minimum breakdown voltage threshold of 30 kV/2.5mm. Both treated and untreated samples were examined.The results indicated that FR3 ester oil exhibited superior dielectric properties, including higher breakdown voltage, flashpoint, and firepoint, as well as lower carbon emissions compared to mineral oil. These findings suggest that natural ester oil has significant potential as a sustainable replacement for mineral oil, particularly in applications where environmental and safety concerns are prioritized.The study recommends further long-term testing under operational conditions to confirm the performance and stability of ester oil in real-world transformer applications. These findings contribute to the growing body of research supporting the transition to more environmentally friendly transformer insulation materials, which could have broad implications for the power industry’s sustainability efforts

Abstract

Pemberian pakan ikan merupakan kegiatan yang memerlukan konsistensi baik dalam waktu pemberian pakan dan jumlahnya. Budidaya ikan di Perum. Bukit Cemara Tidar masih menggunakan sistem manual, yang menyebabkan pembudidaya harus mengatur jadwal untuk pemberian pakan. Sistem pemberian pakan secara manual masih banyak memiliki kekurangan seperti jumlah pakan yang tidak sesuai takaran dan waktu pemberian pakan yang tidak teratur. Ketidakteraturan pemberian pakan ini mempengaruhi kualitas ikan dan biaya pembelian pakan. Untuk mengatasi permasalahan tersebut, maka tujuan kegiatan Pengabdian Pada Masyarakat ini dengan memberikan pelatihan desain dan instalasi alat pakan ikan secara otomatis (automatic fish feeder). Alat ini memudahkan pembudidaya dalam mengatur proses pemberian pakan sehingga dapat menjaga kualitas budidaya ikan dan penghematan biaya pakan. Metode kegiatan yang dilakukan adalah pelatihan dan pendampingan. Peserta diberikan ketrampilan dalam merancang automatic fish feeder, cara pengoperasian dan perawatan. Terdapat 2 alat yang terpasang pada kolam ikan. Berdasarkan pengujian kinerjanya, alat ini sudah bekerja sesuai fungsinya dimana dalam kurun waktu sehari setiap pukul 08:00 dan pukul 15:00 alat akan bekerja untuk memberi pakan pada ikan, waktu aktif servo sudah sesuai perencanaan yaitu 1 menit dengan range berat pakan yang dikerluarkan seberat 18 gram.

Abstract

Konsep urban farming merupakan konsep penanaman yang dilakukan di perkotaan dengan memanfaatkan lahan tanam yang terbatas. Salah satu UMKM di Kota Malang yang bergerak di bidang urban farming yaitu PT Tanduria Agromedia Indonesia, berdiri pada tahun 2021. PT Tanduria Agromedia Indonesia menerapkan konsep ini dengan objek tanaman yaitu tomat dan mentimun pada lahan seluas ± 100 m2. Sistem penyiraman masih dilakukan secara manual dengan ketergantungan pada manusia yang menyebabkan tidak meratanya irigasi setiap area penanaman. Selain itu, ketergantungan terhadap ketersediaan air Perumda Tugu Tirta juga mempengaruhi waktu penyiraman jika terjadi gangguan distribusi air. Upaya yang dapat dilakukan untuk membantu mitra yaitu dengan menerapkan sistem irigasi “drip system” agar proses penyiraman setiap tanaman dapat merata. Teknik penyiraman ini dapat meningkatkan produktivitas tanam dan efisiensi lahan tanam melalui pemasangan instalasi kelistrikan pompa air yang dapat mengatur debit air tandon maupun proses irigasi.

Abstract

Generator sets (gensets) are important tools to be available in public places as a backup source of electrical power, if there is a power outage from the main electrical source. In this study, an evaluation analysis of the generator capacity was carried out in the West Kalimantan secretariat building on April 2023. This building has a total load of 677 kW supplied by PLN medium voltage 20 kV and lowered by a 630 kVA step-down transformer. Current observations were made during Off Peak Load Time at 13.00-15.00 and Peak Load Time at 17.00-19.00. From this experiment, it can be concluded that in April 2023 the highest peak load usage was 568.67 kW or 710.83 kVA. After the calculations have been done, the generator power capacity in the building must be 651.61 kW, while the generators used were two units with a power capacity of 1280 kW. Thus, the generator has met the electrical energy needs of the building. The efficiency of the generator when the genset works for 60 minutes in the building is still relatively low, which is 26.25%. The ACB safety rating used on the outgoing genset to the Low Voltage Main Distribution Panel (LVMDP) has a rating of 2000 A for one genset unit and 4000 A for two synchronous genset units, which is in accordance with the calculation of the safety capability value from PUIL 2011 reference.

Abstract

Segoromadu Substation has two busbars, namely busbar A and busbar B. Busbar A which has nominal voltage of 150 kV has reached a voltage value of 129.38 kV or experienced voltage drop of 13.75%. The percentage of this voltage drop exceeds a predetermined standard. Therefore, it is necessary to design a shunt capacitor which is then modeled and simulated. Based on calculation and analysis result, capacity of shunt capacitor that should be installed on Bus A is 50 MVAR. After the shunt capacitor was installed, based on simulation, there was an increase of 4.87 kV so the voltage afterward became 139.67 kV or only experienced a voltage drop of 3.19%. So, by installing a shunt capacitor with capacity of 50 MVAR, it can increase busbar voltage of the substation. The shunt capacitor also increases the value of reactive power and current flowing to the busbar.
