Abstract

Krisis energi global dan perubahan iklim telah mendorong upaya transisi dari energi fosil menuju energi terbarukan sebagai langkah strategis untuk mencapai keberlanjutan lingkungan dan ketahanan energi. Namun, transisi ini menghadapi berbagai tantangan, terutama dalam hal akses, infrastruktur, dan regulasi, khususnya di negara-negara berkembang. Penelitian ini bertujuan untuk mengeksplorasi bagaimana inovasi model bisnis dan digitalisasi dapat mendukung transisi energi terbarukan di berbagai konteks sosial dan geografis. Dengan pendekatan tinjauan literatur, artikel ini mengintegrasikan temuan dari beberapa studi kasus di Afrika Sub-Sahara, Eropa, dan Amerika Serikat untuk memahami efektivitas model bisnis Pay-As-You-Go (PAYG), kepemilikan saham komunitas, dan adopsi teknologi digital dalam memperluas akses dan keberlanjutan energi. Temuan penelitian menunjukkan bahwa model PAYG berhasil menyediakan akses energi di wilayah terpencil dengan keterbatasan infrastruktur, sementara model kepemilikan komunitas memberikan insentif ekonomi dan keterlibatan sosial dalam proyek energi di Eropa. Digitalisasi juga berperan penting dalam meningkatkan efisiensi penyimpanan dan distribusi energi terbarukan, meskipun masih menghadapi tantangan regulasi dan keamanan data. Kesimpulannya, inovasi model bisnis dan digitalisasi terbukti efektif dalam mempercepat transisi energi terbarukan, namun membutuhkan dukungan kebijakan yang kuat untuk mencapai potensi penuh. Disarankan agar pemerintah memberikan insentif dan mengembangkan regulasi yang adaptif, serta meningkatkan edukasi masyarakat mengenai pentingnya energi terbarukan. Langkah-langkah ini penting untuk mendorong sistem energi yang lebih inklusif, berkelanjutan, dan berdaya saing tinggi di masa depan.

Abstract

Masalah kelistrikan di Indonesia yaitu kebutuhan listrik meningkat lebih pesat dibandingkan pemenuhan pasokan listrik. Kebijakan Energi Nasional (KEN) menargetkan bahwa rasio elektrifikasi mendekati 100% pada tahun 2025. Dalam Grand Strategi Energi Nasional, telah dipetakan rencana penambahan kapasitas EBT sebesar 38 Giga Watt (GW) sampai dengan 2035. Untuk mencapai target tersebut, pemerintah memprioritaskan pengembangan energi surya karena biaya investasi yang rendah dan waktu pelaksanaan yang singkat. Wilayah Gorontalo yang berada di dekat garis khatulistiwa memiliki suhu udara 23,30-33,40 kondisi ini memungkinkan energi terbarukan yang bersumber dari tenaga surya dapat dilaksanakan di provinsi Gorontalo. Penelitian membutuhkan data seperti luas area atap, potensi radiasi lokasi, kemiringan dan orientasi. Hasil simulasi menunjukkan energi AC tahunan pada tahun pertama adalah 335,844 kWh, atap bagian selatan 420m2 menampung modul surya sebanyak 136, atap bagian utara 323,8m2 menampung 100 modul surya, untuk atap bagian barat 592,9m2 menampung 244 modul surya. Modul surya berkapasitas 400wp berjumlah 480 dan membutuhkan 4 inverter yang berkapasitas 40 kWac dengan kapasitas yang dapat dihasilkan PLTS sebesar 192,4 kWp. Setelah memasang PLTS konsumsi energi listrik gedung Fakultas Teknik dapat menghemat penggunaan energi listrik menjadi 585193 kWh/tahun atau 1603,26 kWh/hari. Indonesia's electricity problem is that electricity needs increase faster than electricity supply fulfillment. The National Energy Policy (KEN) targets that the electrification ratio is close to 100% by 2025. In the National Energy Strategy Grand, there has been a plan to add an EBT capacity of 38 Giga Watt (GW) until 2035. To achieve this target, the government prioritizes the development of solar energy due to low investment costs and short implementation time. The Gorontalo region near the equator has an air temperature of 23.30-33.40 allowing renewable energy sourced from solar power to be carried out in Gorontalo province. Research requires data such as roof area, site radiation potential, tilt and orientation. Simulation results show the annual AC energy in the first year was 335.844 kWh, the southern roof 420m2 accommodating 136, the northern roof 323.8m2 accommodating 100 solar modules, for the western roof 592.9m2 accommodating 244 solar modules. The 400wp solar module has a capacity of 480 and requires 4 inverters with a 40 kWac capacity with a PLTS-generating capacity of 192.4 kWp. The Faculty of Engineering building can save electric energy use to 585193 kWh/year or 1603.26 kWh/day after installing PLTS.

Abstract

This study examines the performance comparison of silicon and perovskite as semiconductor materials in photovoltaic solar cell technology. Silicon is known for its long-term stability, consistent power conversion efficiency, and well-established manufacturing infrastructure. However, its high-temperature, energy-intensive production process raises concerns about cost and environmental impact. In contrast, perovskite offers high power conversion efficiency, tunable material structure, and low-temperature fabrication, but faces major challenges in environmental stability and lead-related toxicity. A literature-based approach was applied, analyzing experimental and simulation data to evaluate key parameters such as energy bandgap, efficiency, carrier mobility, and thermal durability. The analysis indicates that combining both materials in tandem configurations presents a promising strategy for developing more efficient, flexible, and environmentally friendly photovoltaic systems

Material elektroda yang digunakan dalam sistem bertegangan tinggi sangat mempengaruhi distribusi medan listrik dan nilai tegangan tembus yang dihasilkan. Oleh karena itu, penelitian ini dilakukan untuk mengkaji karakteristik tegangan tembus dari berbagai jenis material elektroda dalam medan listrik seragam. Studi ini secara khusus membandingkan empat jenis logam, yaitu stainless steel, aluminium, tembaga, dan kuningan, yang umum digunakan dalam aplikasi kelistrikan. Pengujian dilakukan secara eksperimental di Laboratorium Tegangan Tinggi dengan menggunakan konfigurasi elektroda bola-bola, jarum-jarum, dan pelat-pelat pada medium udara. Hasil pengujian menunjukkan bahwa material elektroda memiliki pengaruh signifikan terhadap besar tegangan tembus. Stainless steel secara konsisten menunjukkan performa terbaik dengan nilai tegangan tembus tertinggi pada semua konfigurasi, yakni 8,07 kV (bola-bola), 8,21 kV (jarum-jarum), dan 6,37 kV (pelat-pelat). Sebaliknya, tembaga menghasilkan tegangan tembus terendah, khususnya pada konfigurasi pelat-pelat sebesar 3,27 kV. Aluminium dan kuningan menunjukkan hasil yang bervariasi, namun masih di bawah performa stainless steel

Abstract

The increasing need for electrical energy in Indonesia encourages the development of new renewable energy (EBT), including hydroelectric power plants (PLTA) as an environmentally friendly solution. This research was conducted at the Mentawa Dam, West Toili District, Banggai Regency, Central Sulawesi, to analyze the potential of water energy that can be utilized as a source of micro-hydro power plants (PLTMH). This dam currently functions as irrigation and a tourist attraction, but has significant potential to generate sustainable electrical energy. The research methods include measuring water discharge using the float method, measuring the height of the water fall (head) with an altimeter and GPS, and analyzing the potential for electrical power using the formula P = η ⋅ ρ ⋅ g ⋅ Q ⋅ H. The measurement results show an average water discharge of 3.01 m³ / s and a water fall (head) of 6.56 meters. With a turbine efficiency of 80%, the potential electrical power that can be generated reaches 154.76 kW. This study recommends the use of Kaplan turbines in Mentawa Dam, which are ideal for large discharge conditions and low to medium heads, and can adapt to discharge fluctuations, making it an optimal choice to maximize energy potential. This research is expected to provide sustainable energy solutions for the people of Toili Barat District and support the development of the tourism sector.
