Abstract

Penelitian ini bertujuan untuk menganalisis perbandingan kinerja bendung modular dengan variasi desain struktur modular pada studi kasus Bendung Sungai Gilireng. Bendung modular merupakan solusi yang efisien dan fleksibel dalam pengelolaan sumber daya air, yang memerlukan penyesuaian desain struktur guna memenuhi kondisi teknis dan lingkungan yang spesifik. Dalam penelitian ini, dilakukan perbandingan kinerja beberapa desain struktur modular yang diterapkan pada bendung tersebut, dengan memperhatikan faktor-faktor seperti kekuatan struktur, distribusi tekanan air, serta efisiensi aliran air. Metode analisis yang digunakan mencakup simulasi hidrodinamika dan pemodelan struktural untuk memprediksi respons bendung terhadap variasi desain. Hasil penelitian menunjukkan bahwa variasi desain struktur modular mempengaruhi kinerja bendung, dengan desain tertentu menunjukkan ketahanan yang lebih baik terhadap perubahan beban air dan distribusi aliran yang lebih optimal. Penelitian ini memberikan rekomendasi desain yang lebih efisien untuk penerapan bendung modular pada kondisi serupa, serta memberikan wawasan mengenai dampak desain terhadap kinerja bendung secara keseluruhan.

Abstract

Salt is one of the pond products relied upon by the community in Bulu Cindea Village. The potential for salt in this village is very abundant because raw materials are available at any time. However, the management process is still simple and untouched by technological development. This potential can be maximally developed through the development of geomembrane technology, which is proven to maximize yields and increase income for villagers. The method used by this service team is the socialization and development of salt pond demonstration plots with geomembrane technology. The development of this technology produces the best-quality salt with a relatively short harvest time, so as to increase the selling value of salt products. This community service program can be an example for other villagers, so that later it will have an effect on increasing the knowledge and welfare of residents. This community service activity positively impacted the knowledge of participating villagers, as measured by post-test scores of villagers reaching 74% after implementing this program.

Abstract

ABSTRAK: Penstock merupakan komponen vital dalam sistem pembangkitan listrik tenaga air karena berfungsi menyalurkan aliran air bertekanan dari bendungan menuju turbin. Kinerja penstock sangat dipengaruhi oleh kondisi hidraulik di dalamnya, khususnya fluktuasi debit yang dapat menimbulkan perubahan tekanan, kehilangan energi, dan potensi terjadinya water hammer. Penelitian ini bertujuan untuk mengkaji kinerja penstock pada PLTA Bili Bili di bawah kondisi variasi debit operasi, serta menganalisis pengaruh fluktuasi debit terhadap parameter-parameter hidraulik utama seperti tekanan, kecepatan aliran, dan efisiensi penyaluran energi. Data yang dikaji meliputi karakteristik penstock, variasi debit harian, tekanan operasi, serta data kinerja turbin. Analisis dilakukan untuk mengetahui hubungan antara perubahan debit dengan perubahan tekanan internal, head loss, dan respons sistem terhadap potensi transien aliran. Hasil penelitian menunjukkan bahwa fluktuasi debit memiliki pengaruh signifikan terhadap karakteristik hidraulik penstock. Pada debit tinggi terjadi peningkatan tekanan statis dan kehilangan energi yang lebih besar, sedangkan pada debit rendah penurunan tekanan menyebabkan efisiensi penyaluran energi menurun. Studi ini diharapkan dapat memberikan kontribusi dalam optimasi operasi penstock dan peningkatan keandalan sistem pembangkitan pada PLTA Bili Bili.KATA KUNCIPenstock, Fluktuasi Debit, Hidraulika Penstock, PLTA Bili Bili, Water hammer, Head loss. ABSTRACT: Penstock is a vital component in a hydropower generation system because it functions to channel the flow of pressurized water from the dam to the turbine. The performance of the penstock is greatly influenced by the hydraulic conditions in it, especially discharge fluctuations that can cause pressure changes, energy loss, and the potential for water hammering. This study aims to examine the performance of the penstock in the Bili Bili hydropower plant under conditions of operating discharge variations, as well as analyze the effect of discharge fluctuations on key hydraulic parameters such as pressure, flow speed, and energy distribution efficiency. The data studied included penstock characteristics, daily discharge variations, operating pressure, and turbine performance data. The results of the study show that the discharge fluctuations have a significant influence on the hydraulic characteristics of the penstock. At high discharge there is an increase in static pressure and greater energy loss, while at low discharge there is a decrease in pressure causing the efficiency of energy distribution to decrease. This study is expected to contribute to the optimization of penstock operations and improve the reliability of the generation system at the Bili Bili hydropower plant.Keywords:Penstock, Discharge Fluctuation, Penstock Hydraulics, Bil Hydropower, Water hammer, Head loss
