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 aim of this research is to investigate the influence of carburizing media variation to the microstructure and hardness of low carbon steel in pack carburizing process. The pack carburizing process is after applied to get hardness in the surface and ductility in the middle of metal.This research, carburizing media used is coconut shell charcoal, mangrove wood charcoal with a percentage weight of each - each 900g and 50:50 coconut shell charcoal and mangrove wood charcoal. In this study carburizing process carried out at a temperature of 950ºC with heating time of 180 minutes, 60 minute detention for the three processes Carburizing, The results of this research  indicate that the media coconut shell charcoal is more effective as compared carburizing media mangrove wood charcoal and a 50:50 mixture of coconut shell charcoal and wood bakau.campurang 50:50 coconut shell charcoal and mangrove wood charcoal violence occurs on the outside of 55 HRC With percentage increase of 313.5% at the beginning and harder than the carburizing Media coconut shell charcoal and wood inside the mangrove but resilient.

Abstract

PT. IRNC is a company that operates in the smelter industry. One of the company's production processes is to produce and distribute raw materials in the form of wet Ore into iron and steel products. The distribution of raw materials in this company is continuously ongoing, leading to frequent failures in the functions of the gearbox and the chain of transportation of mineral raw materials. The company has a bustling machine activity but is not associated with the preventive maintenance activities of the machine. One of the activities that can solve the maintenance problem is scheduling preventative maintenance activities and periodic repairs to the gearbox and chain carrier of raw materials. Preventive maintenance is the maintenance activity on the machine which has the purpose of preventing the occurrence of damage, or the maintenance method for the machine planned for the prevention to extend the life of the machine as well as to avoid the failure of function on the machinery that may occur during the production process. This research aims to provide recommendations for scheduled maintenance of the machine with a preventive maintenance approach with the ISMO Method.  The results of the research carried out based on the type of work performed inspection (I) and small repair (S) obtained results respectively for gearbox 13 times inspections (I), and 21 times small repairs (S), while for the chain of transportation of Ore 8 times inspection and four times small reparations, and the number of workers involved 21 people, with the total labor costs of Rp—863,820 million per year.

Abstract

Mekarti Jaya Village is located in the PT Industrial Area. IMIP, the need for industrial workers in the PT area IMIP continues to increase as the investment value in the area increases. To prepare the people and youth of Mekarti Jaya village to be able to take advantage of job opportunities in industries located in the PT area. IMIP needs to carry out training to increase competency, especially in the field of Shielded Metal Arc Welding (SMAW) welding position 2F. The selection of SMAW welding training materials was based on survey results, in which the need for welding specialist workers was the greatest need for industries in the PT area. IMIP. Training activities are carried out for approximately 1 month, starting with the preparation, implementation, and training results stages. The activities were carried out on February 27–29, 2022. Training activities were carried out at the Morowali Metal Industry Polytechnic Machinery Maintenance Engineering study workshop. The training was attended by ± 16 young people and residents of the village of Mekarti Jaya. The results of the training carried out were an increase in understanding and knowledge before and after the training activities were carried out; this was shown by the results of the constant shape of the ridges, welding position 2F, and the results of the post-test.
