Abstract

Kebutuhan energi listrik nasional saat ini masih banyak bergantung pada sumber energi tak terbarukan, sehingga mendorong pengembangan energi baru terbarukan (EBT) sebagai solusi jangka panjang. Salah satu bentuk EBT yang potensial adalah Pembangkit Listrik Tenaga Mikrohidro (PLTMH). Namun, sistem kontrol manual pada pintu air PLTMH memiliki kelemahan, seperti kestabilan yang rendah dan kebutuhan pengawasan yang intensif. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem otomasi inlet gate valve pada prototype screw turbin air untuk menjaga kestabilan daya listrik yang dihasilkan. Penelitian ini dimulai dari studi literatur dan boservasi. Setelah observasi dan studi literatur, dilakukan perencanaan sistem, pemilihan komponen, perakitan sistem, pemrograman sistem, pengujian sistem. Pengujian dilakukan pada tiga variasi tinggi air yang berbeda. Hasil pengujian menunjukkan bahwa sistem mampu menjaga debit air mendekati 1,7 liter/detik dan menghasilkan daya listrik yang relatif stabil dalam rentang 4 – 8 mW, dengan tegangan 2,8 – 3,1 V dan arus 0,9 – 3,5 mA. Dari hasil pengujian tersebut, sistem dapat menjaga kestabilan listrik dalam rentang 4 – 8 mW

The current national electricity demand still heavily relies on non-renewable energy sources, prompting the development of renewable energy as a long-term solution. One potential form of renewable energy is micro-hydro power plants. However, the manual control system on micro-hydro power plants water gates has weaknesses, such as low stability and intensive monitoring requirements. This study aims to design and implement an automated inlet gate valve system on a prototype screw water turbine to maintain the stability of the electricity generated. The study began with literature review and observation. Following observation and literature review, system planning, component selection, system assembly, system programming, and system testing were conducted. Testing was performed at three different water level variations. The test results showed that the system was able to maintain a water flow rate close to 1.7 liters/second and generate relatively stable electrical power within the range of 4–8 mW, with a voltage of 2,8–3,1 V and a current of 0,9–3,9 mA. From the test results, the system can maintain electrical stability within a range of 4–8 mW.
