Abstract

Sumber energi yang paling banyak dimanfaatkan oleh teknologi penunjang kehidupan manusia saat ini adalah energi listrik. Kondisi geografis Indonesia yang sangat luas mengakibatkan distribusi energi listrik belum dapat menyeluruh merambah hingga ke desa. Secara tidak langsung ketersediaan sumber energi listrik mempengaruhi laju pembangunan infrastruktur pada suatu daerah. Salah satu daerah yang belum terjangkau oleh energi listrik adalah Wisata Mangrove dan Reservat Kepiting Desa Mojo, Kecamatan Ulujami, Kabupaten Pemalang. Desa Mojo merupakan salah satu alternatif tempat wisata di Kabupaten Pemalang, akan tetapi belum terdapat fasilitas umum seperti penerangan jalan, pompa air bersih dan bangunan permanen di Wisata Mangrove dan Reservat Kepiting Desa Mojo, kondisi ini antara lain diakibatkan belum terdapatnya sumber energi listrik. Berangkat dari kondisi tersebut tim pengabdian masyarakat Sekolah Pascasarjana Universitas Diponegoro sebagai pengusul bekerjasama dengan Mitra Pokdarwis dan Mitra Pokmaswas Desa Mojo sebagai penerima, merencanakan inisiasi PLTS sebagai sumber energi listrik terbarukan yang dapat diimplementasikan di Wisata Mangrove dan Reservat Kepiting Desa Mojo. PLTS ini rencananya di pasang pada 3 titik yang tersebar di lokasi wisata. Lokasi penempatan titik PLTS diantaranya adalah : Pintu Dermaga 1 Keberangkatan, Pintu Dermaga 2 Kedatangan dan Gazebo. PLTS yang digunakan akan menggunakan konfigurasi off – grid, kapasitas pembangkitan setara 400 Wp, dilengkapi baterai 2 × 60 Ah menggunakan inverter berkapasitas 1 × 1000 VA. Selain melakukan instalasi dan diseminasi teknologi PLTS di Desa Mojo, Pemalang akan dilakukan juga pemberdayaan masyarakat agar dapat mengoperasikan dan merawat PLTS secara swadaya. Dengan ketersediaan sumber energi listrik di Wisata Mangrove dan Reservat Kepiting Desa Mojo diharapkan dapat memacu laju pembangunan infrastruktur, sehingga dapat berdampak pula pada peningkatan daya tarik Wisata Mangrove dan Reservat Kepiting Desa Mojo sebagai salah satu destinasi wisata di Kabupaten Pemalang serta meningkatkan ekonomi masyarakat anggota Pokdarwis dan Pokmaswas Desa Mojo Kecamatan Ulujami Kabupaten Pemalang.

Abstract

The power generation sector contributes to climate change. Mitigation efforts are essential to ensure that the commitment to limiting the global temperature increase below 2°C stays on course. One option is to retrofit an existing power plant with new technology that allows integration with renewable energy. This study examines the incorporation of solar energy systems into the operational processes of coal-fired power plants. Utilizing solar energy to substitute steam extraction from high-pressure feed water heater No. 7. This study analyzes the performance of the power plant before and after the retrofit scenario within both power-boost (PB) and fuel-save (FS) modes. Performances under different load conditions also investigated. The results reveal that the thermal efficiency within both FS and power-boost (PB) modes increased up to 2 % compared to the base scenario. In both power-boost and fuel-save (FS) modes, there is a notable reduction in specific fuel consumption, with power-boost mode experiencing a decrease of 15.05 g/kWh and fuel-save mode showing a decrease of 15.75 g/kWh. Thus, the decreasing coal consumption implies reduced CO2 emissions within both FS and power-boost (PB) modes by 4.69 % and 4,94 %, respectively. Results under different loads show that the solar percentage and the rise in solar-to-electricity efficiency with decreasing loads. When operated in fuel-save (FS) mode, the proportions of solar electricity at VWO, 100%, 75%, and 50% load rates are 5.23 %, 5.53 %, 7.76%, and 11.92%, respectively. Moreover, the LCOE for solar electricity for both modes is 0.0267 USD/kWh, with expected investment returns of 5.87 years.

Abstract

Integrating solar energy into a coal-fired power plant is a promising way to reduce auxiliary load and numerous environmental issues related to the coal-based power generation sector. This paper will discuss the annual performance of PV plant 689 kWp at ash disposal that integrated into 615 MW coal-fired power plant PT xxx, including an estimate of total potential energy that can be generated; analysis of auxiliary load to improve performance and decreasing pollutant emissions by coal consumption reduction. The PV Plant has been operated for at least 2 years, built on an area of 5,000m2, is an On-grid PV Plant system with 11 grid Inverters and has 2,120 solar modules installed. Based on the simulation using Helioscope software, it can generate electrical energy up to 977,442 kWh per year with a performance ratio of 79.3%. The result of the PV plant utilization evaluation shows the amount of electrical energy produced is 1,096,105 kWh in 2021, above the estimation from the simulation. This result means auxiliary power load was decreasing by 0.4932%, It is also considered to be able to save the use of 263.065 kiloliters per year of diesel and also save the use of coal up to 386.634 tons or equivalent to 0.007% coal consumption per year. From an environmental point of view, it is also assessed to reduce CO2 emissions equivalent to 920.729 tons/year and the equivalent of planting 4,602 trees per year.

Abstract

This research aims to calculate thoroughness among data points and analytical simulation curves in discussing corona discharges' (I-V) characteristics. The electrode construction used is the twin towers with dividing angles to the plane (TTDA-P) model in air, with negative DC polarity. An asymmetrical electrical CCP model in the electrode design uses research variations, including active electrode center clamp angles of q = 300, 450, and 600 and active and passive electrode distances (d) of 0.002 m, 0.005 m, and 0.008 m. The simulation curve comes from the analytical formulation of the reduced capacitance type (inserting a multiplying factor k to the sharp corners of the active electrode), with the simulation program being a Python GUI program. The experimental results produced an appropriate error value (t-test value £0.05) and a high percentage of tangent points value. The best curve was achieved at q = 450 and d = 0.008 m, with a t-test value of 0.0313 and the highest percentage of significant tangent points of 92.31%. For all variations q, there is a tendency that the smaller the value of d (the gap length among two electrodes), the greater the deviation distance between the simulation curve and the data points.

Abstract

Solar Power Plant (PLTS) is one type of new and renewable energy (EBT) generated from the Sun. Indonesia is a country that has considerable solar energy development potential of 4.8 Kw h/m2, but currently its utilization is still very low at only 0.01%. This study aims to evaluate the development plan of small-capacity rooftop solar power plants at oil and gas facilities owned by PT Pertamina Gas (Pertagas). This study uses PVSyst and Helioscope software to analyze the potential and efficiency of rooftop solar power plants. The results show that the planned installation of small-capacity rooftop solar power plants (±0.15 kW) in several Pertagas operational areas can support electricity supply for oil and gas distribution in Indonesia. The utilization of solar energy, which is one of the new renewable energy (EBT), is expected to increase the national energy mix in accordance with the government's target. This research provides evaluation and recommendations for the development of rooftop solar power plants at oil and gas facilities to support national energy independence and security.
