Abstract

This study intended to analyze the feasibility of the use of the Power Plant (PLTD) of Ampenan using the break even point (BEP) and sensitivity analysis. That there are several alternatives that can be taken are: first, if the use of the selling price to the public's ability to     Rp. 800 per kWh and a subsidy of Rp. 29.758.612.278 per month, then power plant will have a turnover in the  month to 12 to earn a revenue of Rp. 159.148.857.478. Secondly, if the use of the selling price to Rp. 900 per kWh and a subsidy of Rp. 28.100.809.978 per month, then power plant  will have a turnover in the month to 12  to earn a revenue of Rp. 179.042.464.663. Thirdly, if the use of the selling price to Rp. 1000 per kWh and a subsidy of Rp. 26.443.007.678 per month, then power plant will have a turnover in the month to 12 to earn a revenue of        Rp. 199.936.071.847. Then the results of research using sensitivity analysis to changes in the initial investment is known that the increase in initial investment 600,83% below power plant  is still feasible to operate.. But the power plant  would not be feasible to operate when the increase 600,83% above the initial investment.Furthermore the sensitivity analysis to changes in income are known to decrease in revenue of less than 85,73% of power plant is still worth operating.  But if the decline in revenue was down more than 85,73% power plant operation is not feasible.

Abstract

Every three accidents occur every hour in Indonesia, according to the Director of Road Traffic at the Ministry of Land Transportation, with a percentage of over 50-70 percent and 30 percent of accidents occur due to poor performance of the brake system. Accidents occur due to insufficient braking distance and lack of understanding of the braking characteristics of the vehicle being driven. The aim of this research is to analyze the distance, time and braking force required for an electric car to move until it stops with variations in speed and vehicle load. This research was carried out using an experimental method where a prototype electric car was run by varying the speed and load of the vehicle to obtain braking time and distance and analyzing the data obtained. The shortest braking distance at a speed of 20 km/hour with a vehicle load of 950 kg is 4.39 meters. The longest braking distance is 14.78 meters at a speed of 40 km/hour with a vehicle load of 1050kg. The fastest braking time is at a speed of 20 km/hour with a vehicle load of 950 kg, namely 1.97 seconds. The longest braking time was at a speed of 40 km/h with a vehicle load of 1050 kg, namely 2.76 seconds. The smallest braking force is at a speed of 20 km/hour with a vehicle load of 1050 kg, namely 2098.36 N. The largest braking force is at a speed of 40 km/hour with a vehicle load of 950 kg, namely 4132.65 N.
