Abstract

Indonesia as a country with the largest tropical climate in the world after Brazil, from 27 percent of the tropical zones in the world, Indonesia has 11 percent of tropical areas, including South Sulawesi which is a coffee-producing area which has an area of 690,283 hectares (ha) consisting of People's Plantations 656,067 ha. (95%), Private Basar plantations 19,077 (2.8%), State Large Plantations 15,139 ha (2.2%), South Sulawesi coffee producing areas, especially in Bantaeng spread across Tompo Bulu District. Most of the coffee in Bantaeng is grown in a mixed garden system. However, the drying process has a relatively long time span, so that the coffee harvest has a low level of dryness and the selling price is also not optimal. From these problems, the authors compare the temperature in the dryer with the greenhouse effect system and traditional drying, which is 10% - 30% degrees Celsius hotter using the greenhouse effect. For the efficiency level, the drying time between the greenhouse effect system and traditional drying is about 5-12 days faster using the greenhouse effect drying system.

Abstract

The amount of heat energy wasted on the furnace wall is of concern to researchers who are trying to utilize the heat energy wasted from a furnace wall as a generator or source of electricity. The waste heat from the combustion in the furnace can now be used as a source of electricity. The waste heat is converted into electricity using a thermoelectric generator, the TEG generator is an electrical generator device that converts heat (temperature difference) directly into electrical energy. In this research, the heat used is the cylindrical wall of the furnace with variations in the size of the pump that flows the coolant to the waterblock, to determine the efficiency and magnitude of the power pump used to cool the hot side of the TEG, which produces a high temperature difference and also produces large electrical energy. thermoelectric generator module reused 4 pieces SP1848 27145 SA module.

Abstract

The transmission system is a system that functions to change the torque and speed (rotation) of the torsion engine and has a different speed to keep it moving, the transmission system usually uses gears and fulleys as a rotation successor. Safety shoes are very important protective equipment to prevent injury from falling objects. In addition, it is very important to keep safety shoes clean to avoid falling or slipping while working. In a previous study, namely the Design of a Safety Shoes Cleaner, it did not use a transmission system so that the rotation of the electric motor shaft which was transmitted to the cleaning brush experienced a very large resistance and frictional force. In this study, the transmission system used in the shoe cleaning machine is gear transmission and pulley transmission, the number of gears used is 2 which type of gear used is bevel gear while the number of pulleys used is 5. The purpose of this study was to modify the transmission system of the safety shoe cleaning machine so that it produces counterclockwise rotation on the brush shaft at the top of the machine. This research was carried out in the repair laboratory and workshop of the Morowali metal industry polytechnic from April to September 2022, the research method consisted of planning, designing and manufacturing processes, then testing was carried out so that it could be concluded that the transmission system was running well. By pairing two straight gears on the engine transmission system so as to produce opposite rotation on the upper brush shaft which is transmitted from the motor to the shaft through the gear transmission and fulley belt.
