Abstract

Bendung Candilimo berlokasi di Kabupaten Mojokerto, merupakan infrastruktur sumber daya air dari masa lampau yang berpotensi dimanfaatkan sebagai penghasil energi terbarukan melalui Pembangkit Listrik Tenaga Mikrohidro (PLTMH). Sebagai studi kasus pemanfaatan bangunan irigasi menjadi sarana pembangkit listrik, sejalan dengan tercapainya tujuan pembangungan berkelanjutan (SDGs). Studi diawali dengan kajian hidrologi menggunakan data hujan stasiun periode 2011 – 2024 dan data hujan citra satelit GPM periode 2009 – 2024. Data tersebut kemudian dikalibrasi menggunakan metode regresi sederhana dan regresi Quantile Mapping, setelah itu divalidasi dengan parameter (RMSE, RSR, NSE, KR, dan R) untuk memastikan akurasi hasil data. Debit andalan ditentukan melalui simulasi model menggunakan metode F.J. Mock yang kemudian di ranking menggunakan metode Weibull, menghasilkan debit andalan untuk PLTMH dengan probabilitas 87,3% sebesar 1,66 m3/detik. Hasil debit andalan digunakan dalam analisis hidraulika, untuk mendesain komponen PLTMH. Serta analisis keamanan operasional sistem, khususnya fenomena waterhammer dianalisis menggunakan metode Joukowsky dan pemodelan menggunakan software ANSYS. Berdasarkan besar debit andalan dan tinggi jatuh efektif yang diperoleh, PLTMH di Bendung Candilimo diperkirakan menghasilkan besar energi dengan skema 1 yaitu lama kerja turbin sebesar 527343,53 kWh per tahun. Dari besar energi yang dihasilkan diperkirakan mampu melayani kebutuhan rumah tangga sekitar 175 unit dengan energi per unit 0,45 kW. Kajian diakhir dengan analisis kelayakan ekonomi mencakup perhitungan BCR yang menghasilkan nilai 1,01, dan nilai NPV positif untuk beberapa skenario, serta payback period menghasilkan lama waktu balik modal dari pembangunan PLTMH di Bendung Candilimo.

The Candilimo Dam, located in Mojokerto Regency, is an existing water resource infrastructure from the past that has the potential to be utilized as a renewable energy source through a Micro Hydro Power Plant (MHP). This research serves as a case study for the dual use of irrigation structures as a power generation facility, aligning with the achievement of the Sustainable Development Goals (SDGs). The study commenced with a hydrological assessment using rain gauge station data from the 2011–2024 period and GPM satellite imagery rainfall data from the 2009–2024. The data were then calibrated using the simple regression and Quantile Mapping methods, followed by validation using statistical parameters (RMSE, RSR, NSE, KR, and R) to ensure the accuracy of the data results. The dependable discharge was determined through model simulation using the F.J. Mock method and subsequently ranked using the Weibull method, yielding a dependable discharge for the MHP of 1.66 m³/second with an 87.3% probability. This dependable discharge result was used in the hydraulic analysis to design the MHP components. Furthermore, the analysis of the system's operational safety, particularly the waterhammer phenomenon, was conducted using the Joukowsky method and modeling with ANSYS software.Based on the dependable discharge and the net head obtained, the MHP at Candilimo Dam is estimated to generate energy under Scheme 1, resulting in an annual turbine operating output of 527,343.53 kWh per year. The magnitude of the generated energy is estimated to be capable of serving approximately 175 households with an energy requirement of 0.45 kW per unit. The study concludes with an economic feasibility analysis, including the calculation of the BCR, which yielded a value of 1.01, and a positive NPV for several scenarios. Additionally, the Payback Period calculation determined the investment return time for the MHP construction plan at Candilimo Dam.
