Abstract

Distribution channel power distribution is commonly referred to as a 20 KV Medium Voltage Air Line (SUTM). The main problem that often experiences disturbances in the distribution network function is to deal with disturbances quickly and precisely, the most frequent disturbances experienced in the electric power system are in the distribution network such as disturbances due to lightning, wind, rain, animals and damage. This study aims to determine the disturbances in the 20 kV distribution network and how to maintain the 20 kV SUTM distribution network system in the rose feeder at PT. PLN (Persero) ULP Kampar which is currently being carried out. This research applies a preventive maintenance method known as ROW (Right Of Way) maintenance to increase the effectiveness of the 20 kV distribution network. The results showed that the disturbance was caused by internal factors such as disturbances in the SUTM channel and external factors caused by natural disasters, animals and kites. Preventive maintenance or ROW (Right Of Way) maintenance is implemented as an effort to increase the effectiveness of the distribution network such as felling tree branches that have hit the network, straightening sloping poles, cleaning broken wires, changing lightning arresters, and changing broken pins

Abstract

UKSP is a business that produces 200-300 kg of cassava chips, resulting in 30-45 kg of cassava peel solid waste. The waste is simply thrown away without further processing, causing environmental damage and producing a foul odour. This research utilises cassava peel waste into bioethanol using fermentation and distillation methods. The calculation of electrical energy and cost savings in this study compares E0, E10 and PLN electricity. Bioethanol potential from 30 kg of cassava peel waste is 5.3280 L/h with a purity of 99.9917%. The potential electrical energy generated using E0 reaches 47.34 kWh, while E10 is 46.89 kWh, and PLN electricity is 1.8 kWh. The fuel cost of E0 was IDR 44,4400 for E10 was IDR 33,000 and PLN electricity was IDR 24,336. The results of the comparison between E0 and E10 are used if electricity tariffs increase in the future so that bioethanol can be utilised as alternative energy for UKSP. Based on the results obtained, E10 is an efficient fuel blend that is feasible to use. In the cost analysis, the total investment in cassava peel utilisation is IDR 3,668,895 and the potential savings per year reaches IDR 5,259,024. The pay-back period is 0.70 years.
