Penelitian ini mempelajari analisis ekonomi dan potensi dampak lingkungan penggunaan PLTS dan PLTB yang diyakini tidak menghasilkan emisi selama memproduksi listrik. Untuk analisis ekonomi menggunakan metode LCC dan LCOE. Metode LCA digunakan untuk menghitung potensi dampak lingkungan dari sistem PLTS dan PLTB off grid menggunakan baterai. Hasil penelitian untuk analisis ekonomi menyebutkan biaya LCC PLTS lebih rendah dibanding PLTB, dengan biaya LCC PLTS sebesar Rp 724.448.306, sedangkan biaya LCC PLTB Rp 1.834.313.012. LCOE dari PLTS juga lebih rendah dibanding PLTB, dengan LCOE PLTS sebesar Rp 2.542/kWh, sedangkan biaya LCOE PLTB Rp 6.445/kWh. Potensi dampak lingkungan pada PLTS dan PLTB di Kampung Bungin menggunakan software Simapro menggunakan metode CML IA, didapatkan kategori GWP PLTS 0.09 kg CO2 eq/kWh dan GWP PLTB 0.176 kg CO2 eq/kWh. EBT yang sesuai di Kampung Bungin berdasarkan analisa ekonomi dengan biaya LCOE yang rendah dan analisa berdasarkan potensi dampak lingkungan adalah PLTS.

This study studied economic analysis and the potential environmental impacts of using solar power plants and power plants which are believed to produce no emissions during electricity production. For economic analysis use the LCC and LCOE methods. The LCA method is used to calculate the potential environmental impact of the solar power plant and off grid wind turbine power plant systems using batteries. The results of the study for economic analysis stated that the cost of LCC solar power plant was lower than wind turbine power plant, with the cost of LCC solar power plant amounting to Rp 724,448,306, while the cost of LCC wind turbine power plant was Rp. LCOE from solar power plant is also lower than PLTB, with LCOE solar power plant of Rp 2,542 / kWh, while LCOE wind turbine power plant costs Rp 6.445 / kWh. Potential environmental impacts on solar power plant and wind turbine power plant in Bungin Village using Simapro software using the CML IA method, obtained GWP solar power plant category 0.09 kg CO2 eq / kWh and GWP PLTB 0.176 kg CO2 eq / kWh. The appropriate renewable energy in Bungin Village is based on economic analysis with low LCOE costs and analysis based on potential environmental impacts is solar power plant.

"Menurut data dari United Nations Development Program (UNDP), perairan Indonesia merupakan habitat bagi 76% terumbu karang dan 37% ikan karang dunia. Menurut data Kementrian Kelautan dan Perikanan Indonesia, jumlah potensi ikan di lautan Indonesia adalah sebesar 12,54 juta ton pertahun. Namun, Indonesia masih belum bisa memanfaatkan potensi tersebut karena jumlah produksi perikanan tangkap di Indonesia masih sebesar 6,83 ton per tahun. Salah satu alat tangkap perikanan di Indonesia adalah bagan apung yangmemiliki produktivitas yang baik untuk menangkap ikan. Selain itu, SDA nonhayati Indonesia pun melimpah,seperti minyak bumi misalnya. Namun, Ilmuwan memprediksi bahwa energi minyak bumi Indonesia tersebut akan habis pada 2030. Jika Indonesia masih bergantung kepada energi fossil tersebut dan tidak mencari energi alternatif, maka dikhawatirkan Indonesia tidak siap menghadapi kehidupan yang akan mendatang. Selain ketersediannya mulai menipis, energi fossil pun memberikan dampak yang buruk terhadap lingkungan. Menurut Intergovernmental Panel On Climate Change (IPCC), 1 liter BBM jenis premium dapat menghasilkan 2,35 Kg gas CO2. Jika satu bagan Apung berukuran 10 meter x 9 meter membutuhkan 1.907 Liter selama setahu, maka gas CO2 yang dihasilkan sebesar 4.481 Kg. Salah satu usaha yang dapat dilakukan untuk mengurangi emisi tersebut adalah dengan cara mengganti BBM menjadi tenaga surya yang ramah terhadap lingkungan. Selain itu, penggunakan Pembangkit Listrik Tenaga Surya pun lebih menguntungkan daripada pembangkit listrik generator set dalam jangka waktu minimal 4 tahun.

According to data from the United Nations Development Program (UNDP), Indonesian waters are a habitat for 76% of the world's coral reefs and 37% of reef fish. According to data from the Indonesian Ministry of Maritime Affairs and Fisheries, the potential number of fish in Indonesia's oceans is 12.54 million tons per year. However, Indonesia is still unable to exploit this potential because the amount of capture fisheries production in Indonesia is still 6.83 tons per year. One of the fishing gear in Indonesia is a floating fishing platform that has good productivity for fishing. In addition, Indonesia's non-biological natural resources are abundant, such as petroleum for example. However, scientists predict that Indonesia's petroleum energy will run out by 2030. If Indonesia still relies on fossil energy and does not look for alternative energy, then it is feared that Indonesia is not ready to face life to come. In addition to its diminishing availability, fossil energy also has a bad impact on the environment. According to the Intergovernmental Panel on Climate Change (IPCC), 1 liter of premium fuel can produce 2.35 kg of CO2 gas. If a floating meter measuring 10 meters x 9 meters requires 1,907 liters for one year, the CO2 gas produced is 4,481 kg. One effort that can be done to reduce these emissions is by replacing fuel into solar power that is friendly to the environment. In addition, the use of solar power plants is more profitable than generating sets for a minimum of 4 years."

"PT Trakindo Utama, sebagai dealer resmi Caterpillar® di Indonesia, berkomitmen mendukung 2030 Sustainability Goals dengan target penurunan emisi gas rumah kaca sebesar 30% dari level tahun 2018. Sebagai bagian dari upaya ini, PT Trakindo Utama cabang BSD berencana mengimplementasikan pembangkit listrik tenaga surya (PLTS) untuk mengintegrasikan energi terbarukan ke dalam operasional perusahaan. Berdasarkan potensi Global Horizontal Irradiance (GHI) sebesar 1658 kWh/m² per tahun, penelitian ini merancang tiga desain PLTS dan melakukan analisis tekno-ekonomis untuk mengevaluasi kelayakan investasi menggunakan indikator Net Present Value (NPV), Internal Rate of Return (IRR), dan Discounted Payback Period (DPP). Hasil analisis menunjukkan bahwa desain 2, dengan orientasi modul PV mengikuti kemiringan atap menghadap utara dan selatan, menjadi pilihan terbaik. Desain ini memerlukan biaya investasi Rp 4,453,380,960.00.00, menghasilkan energi sebesar 529.7 MWh/tahun dengan NPV sebesar Rp1,760,413,127, IRR 7%, DPP selama 16 tahun, dan Cost of Energy (COE) sebesar Rp 803.09/kWh dengan persentase energi terserap sebesar 84.11%. Desain 2 dinilai optimal karena efisien secara teknis dan finansial, tanpa memerlukan struktur tambahan, serta mampu memenuhi lebih dari 30% kebutuhan energi listrik bulanan. Implementasi PLTS ini tidak hanya mengurangi biaya operasional dan ketergantungan pada energi fosil, tetapi juga mendukung target keberlanjutan global Caterpillar® serta upaya mitigasi perubahan iklim di Indonesia.

PT Trakindo Utama as the official dealer of Caterpillar® in Indonesia, is committed to supporting the 2030 Sustainability Goals with a target to reduce greenhouse gas emissions by 30% from 2018 levels. As part of this effort, PT Trakindo Utama's BSD branch plans to implement a solar power plant (PLTS) to integrate renewable energy into the company's operations. Based on a Global Horizontal Irradiance (GHI) potential of 1658 kWh/m² per year, this study designs three PLTS designs and conducts a techno-economic analysis to evaluate investment feasibility using indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback Period (DPP).The analysis results indicate that Design 2, with PV module orientation following the roof slope facing north and south, is the best option. This design requires an investment cost of Rp 4,453,380,960, generating 529.7 MWh/year with an NPV of Rp 1,760,413,127, an IRR of 7%, a DPP of 16 years, and a Cost of Energy (COE) of Rp 803.09/kWh, with an energy absorption percentage of 84.11%. Design 2 is deemed optimal due to its technical and financial efficiency, not requiring additional structures, and capable of meeting over 30% of monthly electricity needs. The implementation of this PLTS will not only reduce operational costs and dependence on fossil fuels but also support Caterpillar®'s global sustainability targets and efforts to mitigate climate change in Indonesia.
