Abstract

Pembangkit Listrik Tenaga Air (PLTA) Cisokan merupakan PLTA dengan jenis Pumped Storage (PS) yang direncanakan beroperasi pertama di Indonesia dengan kapasitas sebesar 4x 260 MW pada tahun 2029. Berdasarkan dokumen Studi Kelayakan PT. PLN (Persero) PLTA Cisokan direncanakan untuk beroperasi selama 8 jam untuk memompa air (pumping) dan beroperasi selama 6 jam untuk membangkitkan listrik (generating). Pola Operasi tersebut belum optimal untuk filosofis pengoperasian pembangkit energy storage sebagai energy regulation, karena belum dapat meminimalkan fluktuasi beban, terutama untuk pengisian lembah (valley filling) dan pemangkasan puncak (peak shaving) pada profil beban harian. Diperlukan optimalisasi untuk pola operasi PLTA Cisokan PS sebagai energy regulation di sistem tenaga listrik Interkoneksi Jawa – Madura – Bali pada profil beban harian di sistem 500 kV. Optimalisasi dilakukan dengan meminimalkan variance dari Pres sehingga beban tidak memiliki fluktuasi yang tinggi. Lebih lanjut Optimalisasi dengan prinsip Unit Commitment (UC) dan Economic Dispatch (ED) dilakukan untuk meminimalkan komponen C pada BPP PLTA Cisokan PS. Setelah melakukan optimalisasi penjadwalan, didapatkan bahwa variance dari Pres sesudah dilakukan optimalisasi mengalami penurunan, Capacity Factor (CF) mengalami peningkatan dari keadaan awal bernilai 25% menjadi 27.27%. Komponen A,B dan C pada BPP Cisokan mengalami penurunan, sehingga BPP yang bernilai awal dapat direduksi menjadi Rp. 1095.57/kWh, dengan nilai pengurangan sebesar 12.75 % terhadap BPP awal.

Abstract

This study aims to evaluate the potential implementation of the ISO 50001 Energy Management System (EnMS) at PT XYZ to achieve the decarbonization target. The focus is on strategic and technical planning, involving the analysis of internal and external issues to develop energy policies as well as the formation of energy teams. Technical planning includes energy performance reviews, energy consumption analysis, Significant Energy Users (SEUs), Energy Performance Indicators (EnPI), and operation control plans. The results of the 2022 review show that energy consumption is 947.8 thousand GJ with the main SEU in the Hauling and Mining systems, as well as Hauler and Excavator tools that consume more than 80% of Biosolar B30. EnPI level 1 shows an average energy intensity of 0.08 GJ per WMT, while EnPI level 2 results in a regression of Y=2.113X + 264924 with a determination of 0.892, making 2022 a baseline. The implementation of ISO 50001 has the potential to improve energy efficiency and reduce GHG emissions by up to 30% by 2030, with a target of saving 9.7 million liters of Biodiesel B30. The PDCA approach helps companies achieve targets by focusing on SEU systems and tools.

Abstract

Waterflood is one of the keys in maintaining reservoir health and carrying out oil recovery in the secondary stage. In its development, the implementation of surveillance and monitoring activities is carried out to monitor waterflood performance both from the production and injection sides on a regular basis to maximize production optimization. However, there are many challenges that must be faced in developing waterflood, some of which are maintaining the Voidage Replacement Ratio (VRR) and the production of unexpected water. Therefore, a simpler and easy-to-apply surveillance and monitoring approach is needed. This paper describes how the application of waterflood surveillance and monitoring principles and practices is carried out in carrying out the oil recovery process and monitoring reservoir health. The reservoir health monitoring process includes several aspects such as Voidage Replacement Ratio (VRR) and Water-Oil Ratio (WOR), as well as identification of areas of interest of accumulated oil through the Production Attribute approach. The application is carried out on Field 'X' which has a typical production with a fairly high water cut. This approach was successfully applied to Field 'X' and gave the results of the approach that was quite ideal to be applied

Abstract

Currently, Indonesia is still using fossil fuel power plants. The high use of fossil fuels will harm the environment, therefore to reduce the use of fossil fuels, it is necessary to develop renewable energy power plants, one of which is a solar photovoltaic power plant. This study discusses the economic analysis of planning a soalr photovoltaic power plant at the Taman Melati Depok Apartment which is connected to the PLN network with the PVsyst software. This PLTS plan will be built on the roof of the apartment using an area of 437 m2 with generated power of 90,400 Wp. Using solar modules with a capacity of 565 Wp as many as 160 modules. This PLTS can generate electricity per year 116600 kWh/year. The Cost of Energy (COE) for this PLTS is Rp.735.39/kWh. Economic analysis uses Net Present Value (NPV), Profitability Index (PI), and Discounted Payback Period (DPP) to determine whether this PLTS is feasible or not. Based on the calculation result, the NPV value is Rp. 608,793,939.29, while the PI value is 1.587 and the DPP value is around 12 years and 9 months, which is faster than the project age, which is 30 years. Thus the investment in the Taman Melati Apartment PLTS project is feasible to continue.

Abstract

Jakarta's 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 505.877.074.317

Abstract

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.
