Abstract

This study aims to determine the causes of failure in the coupling gear, reduce or minimize damage that occurs in the coupling gear, determine the hardness of the coupling gear material, and to determine the level of wear and tear on the coupling gear. This research was conducted from July to October 2022, at PT. Semen Padang, ITP Mechanical Engineering Laboratory, FT-Unand Mechanical Engineering Metallurgical Laboratory. The test procedures used in this study are first to identify the damage, hardness testing on the coupling gear, wear testing on the coupling gear. After observing, the types of damage to the coupling gear are obtained, namely in the form of wear. The types of wear and tear on the coupling gear are scoring, plastic flow, and pitting. Based on the results of the hardness test on the first specimen, the average hardness was 41.1 HRC and on the second specimen, the hardness average was 33.5 HRC and on the third specimen, the hardness average was 34.9 HRC. The specimen that has the highest average hardness value is the first specimen with an average hardness of 41.3 HRC. the wear level in test 1 is 0.008 and in test 2 the wear level is 0.004 and in test 3 the wear level is 0.004 and in test 4 the wear level is 0.004 and in test 5 the wear level is 0.004. From the wear test it was found that the type of wear on the coupling gear material is classified as abrasive and fatigue wear because the two materials are rubbing against each other and the eroded material does not stick to each other and there is also fatigue due to the load that is applied continuously so that the material or coupling gear is worn out.

Abstract

This study aims to identify and determine the level of consumer needs related to rice milling machine and, to develop a House of Quality (HOQ) to determine the dominant design requirements and the priority technical characteristics of the tool. The benefit of this research is to facilitate the design development so that it can continue to provide improvements to the quality of the rice grinder so that the quality of the rice produced can be maintained. The research method used is the Quality Function Deployment (QFD) method by conducting a survey to the field which aims to determine the level of consumer needs by distributing questionnaires and seeking information about what farmers need to make the farmer's work easier. Questionnaires were distributed to the community, most of whom work as farmers and workers in rice mills. The research location is in Pariaman Regency and Padang City. The results of this study are the highest priority scale from the aspect of consumer needs, namely fast work with a weight value (3.63) and from the technical response aspect, namely energy needs with a weight value (36.15). Based on the House of quality analysis, design development is focused on improving performance and optimizing energy sources using solar energy.

Abstract

Solar radiation is the light – also known as electromagnetic radiation – that is emitted by the sun. The enormous amount of energy generated from sunlight makes solar cells a very promising alternative energy source for the future. Solar cells also have the advantage of being a practical energy source considering they do not require transmission because they can be installed in a modular manner at any location where they are needed. Various technologies have been developed in the process of making solar cells to reduce production costs to make them more economical. The aim of this research has been achieved, namely to design an Arduino-based solar tracking system, so that by using a solar tracker solar energy can be absorbed and produced more optimally than without using a solar tracker. This is proven based on the results of the Black box test. As for the results of testing the system in a black box, the result is that solar panels can move to follow the sunlight and produce maximum energy. So that this tool can be applied to all regions and can assist the government in efforts to overcome energy problems, especially optimizing alternative energy.
