Pencemaran udara memberikan dampak terhadap meningkatnya kejadian penyakit yang berkaitan dengan pernafasan. Penyebab utama pencemaran udara tersebut adalah gas buang aktifitas transportasi umum dan pribadi, indikator pencemaran udara harus lebih diperhitungkan walaupun jumlahnya kecil. Adanya konsentrasi polutan yang terlalu banyak di dalam ruangan juga dapat menimbulkan gangguan pernapasan dan permasalahan kesehatan lainnya. Tujuan dari penelitian ini adalah untuk mendesain mesin portable hepafis plasma penjernih udara menggunakan UVC dan mengetahui pengaruh sinar UVC terhadap kualitas udara pada ruangan. Metode pelaksanaan yang dipakai dalam penelitian ini yaitu perancangan alat penjernih udara menggunakan UVC 8W-JP-T5-UV dengan cara menguji udara hasil filtrasi yang masuk ke dalam mesin jumlah kadar polutan dan nilai bakteri yang disesuaikan dengan indeks kualitas udara. Â Data dari hasil pengujian alat penjernih udara menggunakan UVC diranacang memakai mikrokontroler berupa arduino uno untuk mengolah hasil pembacaan sensor dan mengirim data. Sensor yang digunakan yaitu MQ-135 untuk membaca kualitas udara, pembacaan ditampilkan pada LCD nilai polutan kualitas udara. Hasil dari pengujian polutan kualitas udara diketahui untuk udara ruangan normal dari 100 ppm ke 46 ppm dan udara ruangan berasap dari 334 ppm ke 46 ppm dimana udara ruangan tersebut baik untuk manusia sesuai dengan Indeks Standar Pencemaran Udara. Selanjutnya untuk nilai angka bakteri hasil pengecekan laboratorium dari hasil pengujian selama 30 sampai 120 menit maka hasil uji angka bakteri sudah memenuhi batas baku mutu yaitu dibawah 500 cfu/m3 hasil pengujian 188 sampai 44 cfu/m3 sehingga mesin uji hepafis plasma menggunakan UVC berpengaruh terhadap pengurangan angka bakteri.

This study aims to explore the potential for biomass-based power plant to accelerate the development of renewable energy to replace the role of fossil energy in Merauke district, South Papua Province. The method used in this study is, first, to collect data and analyze the load on the grid system and the portion of the energy mix as well as the availability of woody biomass from forest areas by making a simulation of the development of a 2 x 12 MW Biomass Power Plant. Second, by conducting experiments to obtain woodchip conversion, as the fuel of the Biomass Power Plant, from the wood log and conversion from Biomass Power Plant capacity to the required biomass plantation area. The results provide an overview of the big potency for developing biomass-based power generation by utilizing biomass from the local industrial plantation forest and show the energy transition towards energy independence. This study can be useful for policy makers and opportunities for entrepreneurs or suppliers of wood biomass, as well. For the future, in terms of fuel efficiency, it is necessary to reduce the plantation area as a source of biomass for power plants by reducing the moisture content of the woodchip to increase the calorific value and utilizing the forest residue. Furthermore, the comparison cost study between fossil power plant and biomass power plant, as well as the strategy for preserving the plantation to ensure a steady biomass supply is conducted.

This study evaluates the impact of an earthquake on a mini-hydropower plant (MHP) and formulates a disaster management strategy to enhance the operational resilience of MHPs against seismic events. Data was collected through interviews with relevant stakeholders, direct observations, and analysis of pertinent documents. The findings indicate that the 2018 Lombok earthquake caused severe damage to the catchment area, triggering increased sedimentation that disrupted the MHPs operation, resulting in decreased electricity production and escalated operational costs. Mitigation measures were implemented and proved effective in reducing debris-related downtime and improving electricity generation. Thes findings are expected to provide guidance for MHP operators in mitigating the negative impacts of earthquakes and similar disasters on plant operations.

AbstrakSelain potensi angin karena bentuk geografisnya, Indonesia juga memiliki potensi angin yang dapat dimanfaatkan dari pergerakan arus lalu lintas di jalan raya atau jalan tol. Pergerakan kendaraan berkecepatan tinggi di jalan raya menghasilkan angin lokal, yang dapat digunakan untuk menghasilkan energi listrik. Angin lokal ini memiliki variabilitas yang lebih kecil, terutama jika lalu lintas jalan raya konstan. Tujuan utama dari penelitian ini adalah untuk mendesain Vertical Axis Wind Turbine yang dapat bekerja pada kecepatan angin rendah. Pada pendekatan teoritis, software Qblade digunakan untuk menganalisa beberapa jenis Airfoil yaitu NACA 0012, NACA 0013, NACA 0014, NACA 0015, NACA 0016 dengan variasi sudu 2, 3 dan 4 angka pada masing-masing konfigurasi aerodinamis. Koefisien performa turbin angin sumbu vertikal yang optimal dapat diperoleh pada simulasi turbin yang menggunakan airfoil NACA 0016 sebesar 1,33 dengan konfigurasi jumlah sudu adalah empat buah pada TSR 3,5 sehingga diperoleh daya sebesar 87,78 watt pada kecepatan angin 5 m/s dan kecepatan putar 300 rpm. Kata kunci: VAWT, Darrieus, Qblade AbstractApart from wind potential due to its geographical shape, Indonesia also has wind potential which can be exploited from the movement of traffic flow on highways or toll roads. The movement of high-speed vehicles on the highway generates local wind, which can be used to generate electrical energy. These local winds have less variability, especially if road traffic is constant. The main objective of this research is to design a vertical axis wind turbines to operate in low wind speed. In the theoretical approach, Qblade software is used to analyze several types of airfoils, namely NACA 0012, NACA 0013, NACA 0014, NACA 0015, NACA 0016 with 2, 3 and 4 number blade variations on each aerodynamic configuration. The optimal vertical axis wind turbine performance coefficient can be obtained in a turbine simulation that uses a NACA 0016 airfoil of 1.33 with a configuration of four blades at a TSR of 3.5 so that a power of 87.78 watts is obtained at a wind speed of 5 m/s and rotating speed 300rpm.

Solar-biomass hybrid power systems (SBHPS) offer a promising solution to global energy and climate challenges by integrating two complementary renewable sources. This study presents a systematic literature review (SLR) based on 543 articles retrieved from Scopus and Web of Science (2014 to 2024), with 76 full texts screened, 26 meeting the inclusion criteria, and 18 scoring ≥4/5 in quality based on CASP and MMAT frameworks. The analysis identifies key advantages of SBHPS, including improved energy efficiency, supply reliability, greenhouse gas emission reduction, and local resource utilization. Conversely, barriers include high capital costs, resource dependency, technical complexity, and policy constraints. The novelty of this review lies in its integrated, multi dimensional synthesis across technical, economic, environmental, and social aspects, filling a gap left by earlier SBHPS reviews. The findings offer practical insights for energy planners, technology developers, and policymakers aiming to implement sustainable and regionally adapted hybrid systems
