Abstract

The growing demand for electricity in the Province of Bali is still largely dominated by the use of fossil fuels and coal. This reliance on conventional energy sources contributes to carbon dioxide (CO₂) emissions and greenhouse gases, which in the long term have a negative impact on the environment. To reduce this dependency, the utilization of renewable energy sources such as Solar Power Plants (PLTS) offers an effective and environmentally friendly solution. The Lecture Building at Udayana University was selected as the study object due to its relatively high electricity consumption. The PLTS system design for this building was based on the available roof area, utilizing all four roof sides. Each side is equipped with 32 solar modules rated at 670 Wp per unit, one inverter with a capacity of 25 kW, and 16 battery units each with a capacity of 200 Ah. The system design was simulated using PVSyst software, and with a total installed capacity of 85.76 kWp, the system is capable of generating approximately 515.8 kWh of electricity per day.

Abstract

Increasing electrical energy consumption in the education sector requires efforts to save on campus buildings. This study aims to identify efficiency opportunities in the Lecture Building of Udayana University using the walk-through audit method. Measurements were made on lighting, air conditioning (AC), elevators, and pumps using lux meters, infrared thermometers, and power quality analyzers. The results showed that the biggest savings came from the air conditioning system of 22,965 kWh/month (15.47% efficiency) through temperature and operating time adjustments. The energy consumption intensity (IKE) value was recorded at 54,145 kWh/m²/year for one floor and 18,048 kWh/m²/year for three floors, far below the standard of 240kWh/m²/year. The other system generates technical recommendations to support the sustainable implementation of green campuses.

Abstract

Faktor penyebab kecelakaan disebabkan karena factor pengemudi dan kendaraan. Hal ini terjadi karena pengamudi kurang memperhatikan kecepatan, tata cara pemuatan, serta beban yang dibawa. Kecepatan serta beban muatan yang berlebih bisa mengakibatkan rem blong. Tata cara pemuatan yang salah juga mempengaruhi kinerja sistem pengereman. Pengujian efisiensi rem yang dilakukan secara statis belum bisa menjamin bahwa kendaraan tersebut dalam kondisi baik. Pada penelitian ini dilakukan dengan pengujian rem road test dengan penambahan beban, kecepatan, dan tata cara pemuatan untuk mengetahui jarak pengereman. Hasil dari penelitian ini menunjukkan bahwa penambahan beban muatan, perubahan kecepatan, dan perubahan tata cara muat dapat mempengaruhi jarak pengereman. Dari perhitungan perlambatan yang telah dilakukan dapat disimpulkan bahwa nilai perlambatan dipengaruhi oleh jarak pengereman, penambahan beban muatan, perubahan kecepatan, dan perubahan tata cara muat dapat mempengaruhi nilai perlambatan.
