Abstract

Indonesia, as the largest archipelagic country, faces significant challenges in providing consistent electricity to its numerous isolated microgrids, many of which rely on diesel generators. The limited operational hours of these systems hinder economic growth, especially in remote regions like Rhun Island. This research aimed to develop an optimized hybrid power system integrating photovoltaic (PV) panels and Battery Energy Storage Systems (BESS) to extend electricity availability and reduce reliance on fossil fuels. Using simulation tools such as PVsyst and HOMER Pro, the study evaluated various configurations to identify the most cost-efficient and sustainable solution. Additionally, Demand Side Management (DSM) strategies, including peak clipping and load shifting, were applied to further optimize the system's performance and reduce operational costs. The findings demonstrated that the hybrid system significantly decreased the Levelized Cost of Energy (LCOE) to $0.431/kWh compared to a diesel-only system. Furthermore, the renewable energy fraction increased to 81.7%, contributing to Indonesia's energy transition goals. This research offers a replicable model for other small islands, promoting sustainable energy solutions and supporting local economic development by ensuring a stable 24-hour power supply. The implications suggest that adopting hybrid systems with DSM can accelerate energy equity and environmental sustainability in remote areas.

Abstract

An efficient electrical system is essential to meet the energy needs of the community without incurring high operational costs. This study aims to compare the total operational costs of power plants during three extreme time periods: low load (00:00–05:00), medium load (06:00–18:00), and high load (19:00–23:00), and to determine the most efficient combination of power plants using the Unit Commitment (UC) method based on priority list techniques. The study was conducted on the Bengkulu regional power system with the assumption of zero startup costs due to data limitations. Simulation results show that coal-fired power plants (IPP), hydroelectric power plants, and micro-hydro power plants serve as the base load power plants that are always active due to their low operational costs, while diesel power plants are only used as supplements when load exceeds the capacity of the main power plants. The lowest total operational cost occurs during low-load periods at Rp 40,936,446/hour, while the highest cost occurs during peak-load periods at Rp 65,040,329/hour. This finding confirms that optimizing the combination of power plants based on cost efficiency can significantly reduce operational expenses. In the future, it is expected that the electricity system can adopt smart grid technology to reduce, even eliminate, the use of inefficient diesel power plants.

Abstract

Pulau Sebesi di Provinsi Lampung saat ini masih mengandalkan Pembangkit Listrik Tenaga Diesel (PLTD) untuk kebutuhan energinya, dengan beban rata-rata sebesar 100 kW dan biaya pokok produksi (BPP) listrik mencapai Rp 5.539/kWh. Tingginya BPP serta target pemerintah untuk mencapai Net Zero Emission pada tahun 2060 mendorong perlunya konversi ke sistem pembangkit energi terbarukan. Penelitian ini bertujuan untuk menganalisis keekonomian dan optimasi biaya dari sistem Hybrid Renewable Energy System (HRES) di Pulau Sebesi yang menggabungkan PLTD dengan Pembangkit Listrik Tenaga Surya (PLTS), Pembangkit Listrik Tenaga Hidrogen (PLTH2), serta Battery Energy Storage System (BESS).Tiga skema simulasi dilakukan: Skema 1 (Hybrid PLTD dan PLTS), Skema 2 (Hybrid PLTD dan PLTH2 150 kW), dan Skema 3 (Hybrid PLTD, PLTH2 150 kW, dan PLTS 300 kW). Simulasi dilakukan menggunakan aplikasi Homer untuk menghitung Levelized Cost of Energy (LCOE), biaya operasional, serta emisi Gas Rumah Kaca (GRK). Hasil penelitian menunjukkan bahwa semua skema layak diimplementasikan, namun Skema 3 paling optimal dengan LCOE terendah sebesar $0.247/kWh, pengurangan emisi CO hingga 99,1%, serta Return on Investment (ROI) tertinggi sebesar 101,4%. Skema ini terbukti paling efisien dan menguntungkan dari segi ekonomi dan lingkungan. Penelitian ini memberikan referensi penting bagi PT PLN (Persero) dalam pengembangan pembangkit energi baru terbarukan di wilayah Terdepan, Terluar, dan Tertinggal (3T) untuk mendukung program dedieselisasi serta pemerataan akses listrik di seluruh Indonesia. pemeliharaan PLTP maupun PLTU. Selain itu import daya dari Sumbagsel perlu dilakukan filter pemilihan renewable energi untuk mengurangi dampak emisi yang berlebih dalam menjaga keandalan sistem.

Abstract

This study analyzes power losses due to load imbalance and the calculation of losses in distribution transformers at the Merauke City Customer Service Unit (ULP). The results show that most distribution transformers on the Angkasa, Bampel, Parako, Kompi, and Ermasu feeders experienced load imbalances exceeding the 20% tolerance limit according to SPLN D3.002-1:2014 standards, contributing to increased neutral currents and power losses, particularly in transformers with heavy loads and uneven phase distribution. After phase current balancing using ETAB 19, significant reductions in neutral current and losses were observed, with transformer efficiency increasing by an average of 2-5% per unit. A feeder-based, data-driven balancing strategy, involving the redistribution of load from dominant phases to deficit phases along with regular monitoring, proved effective in improving distribution system efficiency, extending transformer lifespan, and enhancing voltage quality for customers. These findings provide an operational basis for PLN ULP Merauke to prioritize distribution network improvements, maintain a minimum bus voltage profile of 93–95%, and reduce operational costs through regular load balancing.

Abstract

The development of electricity infrastructure is a vital component in supporting economic growth and sustainable energy supply, especially in strategic areas such as Bekasi Regency which is part of the Greater Jakarta metropolitan area. This area is experiencing rapid development as a residential, industrial, and commercial center, thus requiring a reliable and efficient electricity system. This study aims to analyze the financial feasibility of the construction of High Voltage Cable Ducts (SKTT) as an alternative to High Voltage Overhead Ducts (SUTT) for the completion of the IBT 3.4 Tambun outlet, taking into account space limitations in densely populated areas, community resistance, and spatial complexity that often hinder the construction of SUTT in urban areas. Based on the calculation of the present value (PV), the total cost of SKTT is Rp 594,667,106,857 consisting of initial investment and cable replacement in the 25th year which is lower than the total cost of SUTT of Rp 654,218,062,903, which includes construction costs, land acquisition, and maintenance. Sensitivity simulations show that the SKTT remains more economical even if its investment costs increase by up to 10%. These results demonstrate that the SKTT is a technically, socially, and financially feasible solution for densely populated areas like Bekasi.

Abstract

Penelitian ini menganalisis dampak penetrasi Pembangkit Listrik Tenaga Surya (PLTS) terhadap struktur biaya operasional dan Biaya Pokok Penyediaan (BPP) dalam sistem ketenagalistrikan Indonesia yang masih didominasi batubara. Berbeda dengan studi terdahulu yang berfokus pada Levelized Cost of Electricity (LCOE) di tingkat proyek, penelitian ini menguji dampak sistemik pada tingkat utilitas menggunakan data tahunan PT PLN (Persero) periode 2012–2024 yang bersumber dari RUPTL dan laporan keuangan konsolidasian. Pendekatan Partial Least Squares–Structural Equation Modeling (PLS-SEM) digunakan untuk menguji hubungan struktural antara Component Cost, Performance pembangkitan, dan BPP. Hasil menunjukkan bahwa Component Cost berpengaruh positif dan signifikan terhadap BPP (β = 1,073; p < 0,05), sementara Performance tidak berpengaruh signifikan terhadap BPP (β = 0,263; p > 0,05). Nilai R² = 0,891 dan Q² = 0,910 mengindikasikan daya jelaskan dan relevansi prediktif yang sangat kuat. Temuan ini mengkonfirmasi bahwa PLTS Indonesia masih berada pada tahap penetrasi awal, belum mencapai skala transformasional untuk menurunkan biaya sistemik. Penelitian ini berkontribusi pada literatur ekonomi energi melalui kerangka system-level cost elasticity dan memberikan implikasi kebijakan terhadap perencanaan RUPTL serta reformasi subsidi energi.

Abstract

In a construction project, the key indicators of success are cost, quality, and time performance. To achieve these targets, proper planning, scheduling, and execution control are essential. The Earned Value concept is one of the integrated control methods used to manage both project cost and schedule effectively. This method is applied to analyze project performance and to forecast project completion by providing performance information at a specific reporting period and generating estimates for the total cost and time required to complete the entire project. This final project presents an analysis using the Earned Value Concept to evaluate the contractor's performance, as well as the cost and time aspects of the 150 kV Tayan – Sandai transmission line construction project. The project experienced delays caused by factors related to manpower, methods, materials, and the environment.
