Abstract

PT. XYZ is a manufacturing company engaged in the production of cables and conductors such as busbars. Busbar is a copper bar used to distribute electric power. The problem that occurs at PT. X is that there are still reject products in the busbar production The reject criteria found are as follows: bent busbar, scratched visual, oxidized visual, cracked visual during bending test. This aims of this research are to reduce the total rejects in busbar products by proposing improvements to the busbar production process using the six-sigma method. The data used in this study consisted of primary data (results of discussions with production managers, quality control managers and engineering staff and research in field) and secondary data types and total rejects within 21 months. The results of this research found that at the define stage scratched busbar and bent busbar are the dominant type of busbar that will be improved in this research. At the measure stage, the company sigma value is 3.607. This result can be used to propose quality improvement for the busbar production process whisch is obtained so that the company can reduce the number of defective products and improve product quality.

Abstract

One of the universities that is intensified to conduct research in producing innovative products is Andalas University (UNAND). Andalas University has 83 innovative products, including Gambier products from processing in the Teaching Industry Gambier UNAND. These processed Gambier products have not all been successfully commercialized. The obstacle usually experienced is that inventors need help knowing how to commercialize the product and whether the product has innovated. This study aims to determine the level of innovation readiness of three products in the Gambier sector that have never been studied before. Data collection was carried out through interviews with each product inventor and filling out questionnaires on the Katsinov Meter measuring instrument. Analysis of the measurement results was carried out using a fishbone diagram. Based on measurements, Fitopure (+)- Catechin and Unca Tea products are at Katsinov level 4 and level 2, respectively. Meanwhile, the scrub of Gambier products did not pass any Katsinov level. Some of the causes are that there is no business model concept, the Company has yet to conduct market research, it has not finished identifying market expansion needs, and it has not finished assessing technological and financial risks. Suggestions that can be given are that the Company needs to form a business model concept, conduct market research, expand the market, and assess technological and financial risks

Abstract

Various problems that arise are caused by the school quality zoning system policy, low student learning motivation, and low student competence. The purpose of this study is to analyse the problems/inhibiting factors of the zoning system. This study uses the sequential mixed methods method, especially the sequential explanatory strategy. Based on the results of the study, it was found that the advantages of the zoning system are cheaper, such as cheaper student transportation costs to school, no discrimination against favourite schools, and encouraging teachers to be more creative in designing learning that is in accordance with student conditions, while the problems and supporters of the implementation of the zoning system in accepting new students. Some implications and recommendations obtained from this study. First, for the central government, considering that the competition for prospective students with the zoning system is getting tighter, the Central Government must adjust the existing provisions by reducing the percentage of the zoning system path and increasing the percentage of the achievement path. Second, the Provincial Government in determining the zone does not only refer to the distance between home and school but also needs to optimize the involvement of community leaders in determining the zone of each school.
