    Jakarta\u27s dense population creates problems with the high daily waste production, which reaches 7,500 tons. On the other hand, the open dumping method in the final waste treatment creates another problem in the form of greenhouse gas emissions. The regional government also issued a policy to reduce greenhouse gas emissions to achieve net zero emission by 2050. The solution that then emerged for the two problems above was to convert waste into electrical energy through incineration technology. This study aims to conduct an economic analysis in the context of implementing incineration technology. The results showed that the minimum capacity for economic feasibility was 8 MW with an LCoE of IDR 2,578.32/kWh, 429 tonnes of waste per day, an IRR of 8.63%, and an NPV of IDR 115,038,835,638.12 at an investment value of IDR 505.877.074.31

    Estimation of Health Impacts and Externality Costs with the Robust Uniform World Model in the Muara Karang Generation Units

    To encourage national economic growth, efforts are made to maintain electricity availability in Indonesia. Until now, the need for electrical energy in Indonesia is still supplied by fossil fuel power plants, especially Steam Power Plants and Gas Steam Power Plants. One of the negative impacts arising from electricity generation activities is air pollution. Air pollution is produced in the form of waste gases such as PM10, SO2, NO2, and these gases causes global warming and impact of human health. In this study, the magnitude of the negative impact calculated based on the impact on public health, which will then be limited to economic value (cost of externalities). Cost of externalities are conditions when the effect of the production of goods or services imposes costs or benefits on other parties, and these costs are not reflected in the price charged for the goods or services produced. The estimation of public health impacts and externality costs calculated in this study comes from power plants operating at the Muara Karang Generation Unit using Robust Uniform World Model (RUWM). The research results show that the amount of health and externality costs obtained for each power plant are different because each power plant has different operating conditions. In PLTGU Block 1, the resulting externality cost was 18,51 cents USD/kWh, PLTGU Block 2 was 3,05 cents USD/kWh, and PLTGU Block 3 was 1,75 cents USD/kWh. The two Unit of PLTU Muara Karang generate different externality costs, namely 1,52 cents USD/kWh for PLTU Unit 4 and PLTU Unit 5 of 1,10 cents USD/kWh

    Mitigasi Biaya dan Resiko Pemanfaatan Trafo Obsulate & Kondisi Buruk pada PLN UPT Palembang untuk Mendapatkan Biaya Operasional yang Optimum

    Trafo merupakan salah satu aset transmisi yang berfungsi menyalurkan daya dari tegangan tinggi menjadi tegangan rendah ataupun sebaliknya pada frekuensi yang sama. Pada dasarnya trafo akan mengalami pemburukan, baik karena lama operasi, pembebanan yang tinggi, terkena gangguan maupun perubahan suhu lingkungan. Hal ini mengakibatkan pemburukan material isolasi, kerusakan salah satu komponen trafo yang mengakibatkan penurunan efisiensi trafo. Di PLN UPT Palembang memiliki 57 buah trafo yang pada tahun 2024 ada 5 buah trafo terhitung sudah beroperasi selama >30 tahun, sementara PLN menetapkan umur operasi trafo yang berusia di atas 30 tahun termasuk dalam kategori sangat tua. Dari pengujian terakhir, diperoleh hasil inspeksi CBM level 1 berupa kebocoran minyak trafo serta hasil inspeksi CBM level 3 juga memperlihatkan adanya pemburukan isolasi bushing maupun belitan dengan hasil uji tan delta bernilai lebih dari standar 1%, tidak hanya itu saja tapi Indeks Polaritas dari tahanan isolasi pun sudah melebihi standar. Apabila tidak dilakukan tindakan perbaikan, dikhawatirkan trafo akan mengalami breakdown. Tindakan perbaikan yang bisa dilakukan meliputi penggantian komponen trafo ataupun penggantian trafo secara keseluruhan mengingat usianya yang sudah sangat tua. Untuk memutuskan tindakan mitigasi yang cocok, maka dilakukan analisis risk, cost, dan benefit menggunakan analisis multikriteria. Harapannya, 5 buah trafo obsulate dan kondisi buruk PLN UPT Palembang tetap dapat beroperasi optimal dan andal. Setelah dilakukan analisis multikriteria, maka didapatkan opsi mitigasi penggantian trafo secara keseluruhan lebih baik sebesar 0,50 dibandingkan perbaikan ataupun penggantian komponen trafo, serta secara signifikan menurunkan risiko kegagalan sebesar 60,54% yang berdampak 38% deviasi terhadap target kinerja perusahaan serta memenuhi regulasi lingkungan hidu
