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 standard box car design has a large drag and wake area which results in high fuel consumption. One way to reduce drag and wake area is to modify the box car design. Modifications were made by adding an aerokit spoiler and deflector to a standard box car which is expected to reduce drag and wake areas. The next step is to design a simulation using CFD-based CAD. The analysis was carried out with three variations of speed, namely 60 km/hour, 80 km/hour and 100 km/hour. The simulation results show that the design of the box car with the modification of the addition of aerokit spoilers and deflectors can reduce the drag and wake areas.

Abstract

Salah satu sistem mekanisme yang mengontrol dan mendistribusikan oli pelumas ke komponen mesin yang berputar adalah sistem pelumasan. Bagian-bagian mesin yang bergesekan satu sama lain rentan terhadap keausan, yang dapat dihindari atau dikurangi dengan pelumasan. Operasi dasar sistem pelumasan adalah menyemprotkan pelumas pada bagian-bagian mesin yang bergerak yang bersentuhan satu sama lain selama penyalaan.Mesin frais merupakan salah satu mesin yang memiliki sistem pelumasan. Pada mesin frais, sistem pelumasan berada pada meja mesin yang bisa bergerak dalam sumbu X, Y dan Z. Pelumasan meja mesin frais perlu dilakukan setiap hari saat mesin akan digunakan. Menurut standar umum mesin frais, pelumasan dilakukan dengan cara menarik tuas pompa pelumas sebanyak empat kali. Namun, karena sistem pelumasan dilakukan secara manual oleh operator, hal tersebut terkadang terlupakan oleh operator. Melihat hal tersebut, peneliti melakukan modifikasi sistem pelumasan yang bertujuan supaya bagian-bagian mesin yang mengalami contact sliding dapat beroperasi dengan otomatis. Metode penelitian ini dengan cara memodifikasi sistem pelumasan manual yang telah ada pada mesin menjadi otomatis yang dikontrol melalui arduino uno dan digerakkan oleh motor stepper. Pada saat pompa pelumas terhubung arus listrik, secara otomatis pompa akan memompa sebanyak empat kali.Motor akan berhenti berputar setelah selesai memompa. Sehingga prototype yang dibuat mampu bekerja pada mekanisme sistem pelumasan mesin frais konvensional secara otomatis menyemprotkan 10ml oli.

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.

Abstract

This aims of this study to determine the effect of multilayer welding on ASTM A106 type carbon steel pipe material on the characteristics of the microstructure, hardness and maximum tensile strength of the material. ASTM A106 type carbon steel pipe is used as a raw material for welding using the Shielded Metal Arc Welding (SMAW) method. Welding on material joints is carried out in three layers (multilayer welding), namely the root pass, hot pass, and capping layers. There are two variations of welding specimens carried out in this study, namely in specimen 1 the currents used were 60, 70 and 80 A while in specimen 2 the currents used were 70, 80 and 90 A. To determine the effect of current variations on each specimen carried out three include Vickers Testing, microstructure testing and tensile testing. The results show that the base metal area is dominated by the ferrite phase, which indicates that the area has low hardness while the weld shows more perlite phase than ferrite besides the grain size is smaller and denser; this indicates that the hardness level will increase when compared to base metal. The results of the hardness test for all variations of the specimen concluded that the highest hardness value was in the weld. From the tensile test, it can be concluded that specimen 2 has a greater tensile strength of 2.5% when compared to specimen 1.
