Abstract

Waste is a significant problem that needs to be urgently addressed. If waste is left untreated and disposed of improperly, it can become contaminated by bacteria, viruses, and other toxins that pose serious risks to humans. In this study, researchers designed and created a portable incinerator that utilizes used oil fuel. The study aimed to determine the highest temperature that can be achieved when incinerating wet and dry waste at weights of 5000 grams, 3000 grams, and 1000 grams. Additionally, performance of portable incinerator was evaluated based on the combustion rate and fuel consumption. The result show that the maximum temperature generated by both dry and wet waste is 450 degrees Celcius. The maximum volume of waste that can be loaded into the combustion chamber is 5000 grams. The results show that the maximum combustion rate of the portable incinerator for dry waste weighing 1000 grams is 196.85 gr/s.The maximum burning rate for wet waste weighing 1000 grams is 165.56 gr/s. The minimum fuel consumption produced from dry waste weighing 1000 grams is 300 ml of used oil. And the maximum fuel consumption is produced from wet waste weighing 5000 grams, namely 1000 ml of used oil.

Abstract

Pada motor matic dipengaruhi oleh beberapa faktor salah satunya yaitu bergeraknya sliding sheave yang ditekan oleh pemberat atau roller berdasarkan putaran mesin, jika pemberat atau roller semakin ringan maka menyebabkan puli lebih melebar. Maka perlu dilakukan penyesuaian berat roller dengan tujuan agar mendapatkan tenaga yang optimal sehingga mampu melakukan akselerasi yang lebih tinggi. Motor yang akselerasinya tinggi membutuhkan lebih banyak bahan bakar untuk menghasilkan tenaga yang lebih besar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh berat roller CVT terhadap torsi, daya dan konsumsi bahan bakar spesifik. Untuk pengujian torsi dan daya dilakukan dengan alat dinojet 250i pengujian dilakukan pada rpm 5500 rpm, 6000 rpm, 6500 rpm dan 7000 rpm. Untuk pengujian konsumsi bakar spesifik alat yang digunakan adalah burret, pengujian dilakukan dengan cara melihat pengurangan bahan bakar pada burret selama 30 detik dilakukan pada rpm 5500 rpm, 6000 rpm, 6500 rpm dan 7000 rpm. Dari data pengujian torsi dan daya menunjukkan bahwa masing-masing roller akan mengalami peningkatan grafik data pengujian torsi dan daya disetiap rpm dan dari data pengujian konsumsi bahan bakar spesifik menunjukkan bahwa masing-masing roller akan mengalami penurunan grafik data pengujian konsumsi bahan bakar spesifik di setiap rpm.

Abstract

The growing need for efficient night lighting in natural tourist destinations highlights the importance of reliable and sustainable energy solutions. This study analyzes the optimization of solar-based lighting at Bukit Kunci, Indonesia, using the Open Energy Modelling Framework (OEMOF) combined with real-time monitoring via the IoT ThingSpeak platform. Photovoltaic (PV) panel data recorded at 15-second intervals during February–July 2025, yielding 532,520 records, were cleaned and aggregated as input to model the interaction of PV, batteries, LED lights, inverters, and backup generators, to minimize lifecycle cost and energy loss. Results indicate that the current PV capacity (0.4 kWp) supplies less than 50% of lighting demand, with a high levelized cost of energy (≈9.2 USD/kWh) and low reliability (self-sufficiency 3–22%). Optimization through capacity expansion (≈224 modules, ≈1.25 kWh storage) eliminated load loss probability and reduced LCOE to ≈0.05 USD/kWh. This approach demonstrates OEMOF’s potential to enhance system efficiency, ensure reliable night lighting, and support eco-tourism while offering replicability for rural destinations.

Abstract

Bukit Kunci in Bangowan Village, Jiken District, Blora, is a tourist destination offering flower gardens, photo spots, camping areas, and glamping houses. However, the location faces water supply issues, particularly for the bathroom and prayer room needs. Currently, water is pumped from a traditional well using a small centrifugal pump, but limitations in pump capacity and electricity make it difficult for water to reach the surface with a large flow rate. The PKM program aims to meet the clean water needs in Bukit Kunci, provide additional electricity from a solar power plant, and enhance the partner's knowledge in operating and maintaining solar power plant equipment. Test results showed that the water pump powered by a solar power plant was able to function well, with a flow rate of 10 liters per minute and a time of 2.9 hours to fill a 1200-liter tank. Additionally, a 200 Watt Peak solar power plant was used to operate a 770 Watt water pump with a 1000 Watt inverter and a 1000 Ah battery.Through training, the partner's knowledge of solar power plant operation and installation improved. The community’s income increased by 50% after their water needs were met. In the future, increasing the capacity of the solar power plant is expected to make Bangowan Village an Energy Independent Village, without reliance on the national electricity grid (PLN)
