Pembangkit listrik tenaga hibrida (PLTMH dan PLTS) menjadi alternatif penyediaan daya listrik untuk menjangkau daerah terpencil. Pada penelitian ini, perencanaan penyediaan daya listrik dilakukan menggunakan software HOMER untuk menemukan konfigurasi sistem pembangkit listrik tenaga hibrida yang optimal. Konfigurasi sistem dimodelkan terdiri dari turbin air, panel surya, konverter, dan baterai. Di desa Kawinda To’i terdapat PLTMH 200 kW yang sudah tidak beroperasi lagi. Sehingga perlu dilakukan pengaktifan kembali PLTMH. Langkah awal, dilakukan analisis simulasi hujan-debit untuk melihat ketersediaan debit di DAS Oi Marai. Analisis simulasi hujan-debit menggunakan metode pendekatan NRECA karena dilokasi penelitian tidak terdapat AWLR (Automatic Water Level Record). Simulasi pada HOMER menghasilkan konfigurasi sistem yang optimal berdasarkan NPC terendah. Diperoleh konfigurasi sistem berupa kombinasi 600 kW panel surya, 196,2 kW turbin air, 600 baterai, dan 300 kW konverter dengan nilai NPC sebesar $3.123.007 dan COE sebesar $0,369/kWh. Energi listrik yang dihasilkan mendapat suplai dari PLTMH sebesar 59% dan dari PLTS sebesar 41%.

Measurement Line

Numerical modeling of the problem of dam monitoring by the Electrical Resistivity Tomography method is carried out. The mathematical model is based on integral equations with a partial Fourier transform with respect to one spatial variable. It is assumed that the measurement line is located across the dam longitude. To approximate the shape of the dam surface, the Radial Basic Functions method is applied. The influence of locations of the water-dam, dam-basement, basement-leakage boundaries with respect to the sounding installation, which is partially placed under the headwater, is studied. Numerical modeling is carried out for the following varied parameters: 1) water level at the headwater; 2) the height of the leak; 3) the depth of the leak; 4) position of the supply electrode; 5) water level and leaks positions are changing simultaneously. Modeling results are presented in the form of apparent resistivity curves, as it is customary in geophysical practice.

Water Level Monitoring

Monitoring water levels of lakes, streams, rivers and other water basins is of essential importance and is a popular measurement for a number of different industries and organisations. Remote water level monitoring helps to provide an early warning feature by sending advance alerts when the water level is increased (reaches a certain threshold). The purpose of this report is to present an affordable solution for measuring water levels in water sources using IoT and LPWAN. The assembled system enables recording of water level fluctuations in real time and storing the collected data on a remote database through LoRaWAN for further processing and analysis.
