Abstract

Fish feeder machine is a machine designed to perform a feeding process that works automatically according to a predetermined feeding schedule, this machine can help improve efficiency both in terms of feed quantity and time in the feeding process. The purpose of designing and calculating machine elements in this Fish Feeder is to calculate parts of machine elements, determine the concept of machine design, draw machine drawing detail, and determine bill of material. The manufacture of this machine uses approach method of James H Earle and concept selection using the method of Stuart Pugh, drawing software using Solidworks 2015 and working drawing using ISO Standard. The design of the throwing machine that has been made is the result of a literature approach and field surveys (direct surveys at the Fisheries Service and at the Fish Seed Center where fish feed throwing machines are needed). This machine needs a continuous process of development and testing

Abstract

Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems is the lack of clean water and the PLN electricity network. In 2020, a desalination facility named Sidesi Mas will be built in Bondan Hamlet with a capacity of 240 liters/hour and using the reverse osmosis principle. The energy source for desalination uses a solar power plant (PLTS). Desalination management requires economic analysis, especially in determining the selling price of desalinated water. The cost of producing desalinated water can be calculated using the Cost of energy (CoE) value of the PLTS or the costs incurred to produce electrical energy per 1 kWh. To get the PLTS CoE, this article discusses a simulation to analyze the performance of PLTS desalination systems with Homer software. Homer performs analytical calculations based on a location input, solar energy potential, capacity, and costs of PLTS components as well as electrical load data. The simulation results show that PLTS energy production is 535 kWh/year, the CoE value is IDR 21,975/kWh and the production cost for producing clean water is IDR 183.13/liter.

Abstract

Electric bike is environmentally friendly vehicle because it doesn’t cause air pollution and it can uses electric from renewable energy sources to charge battery. Here is a lot of studies about electric bike in Indonesa, but only a few topic about electric bike for uphill climbing. In this study, electric bike will be designed for a load of 80 kgs to overcomes the uphill road at 21° of elevation. The design process contains activity such as calculation and selection of electric motor, drafting and manfacturing the frame, and riding test on flat road and uphill road at 21° of elevation. The results of design, electric bike uses 2000 watt BLDC motor, 48V 20Ah of battery, 13 teeth at front sprocket and 48 teeth of rear sprocket. From the riding test results, the bike’s maximum speed is 35 km/h reached on 5 seconds on flat road. While on uphill road with elevation of 21°, the bike’s maximum speed is 10 km/h reached on 10 seconds. The conclusion from this study that the electric bike are able to meet the needs to overcome uphill road.
