Abstract

Residential buildings built are mostly non-structural buildings that add the greatest amount of damage. Problems that occur namely, reduced public awareness in terms of earthquake disaster management which is included in the construction of residential buildings in accordance with waterproof standards for educational education activities or providing assistance to the community about how to process and how to make houses that have earthquake resistant structures. The expected outcome is that the Brani village community is increasingly aware of the dangers posed by the earthquake and is understood to make earthquake resistant structures at home, Making knowledge for Brani villagers as material for repairs and overhauling the structure of residential buildings in order to avoid the dangers posed by earthquake. There are two methods used, namely community education and surveys. Community education through material, and discussion about science and technology materials. Lectures are used to provide knowledge about earthquake hazards and how to create earthquake-friendly residential structures. Evaluation and validation are done by questions and answers and discussion of respondents' answers. The number of respondents who participated in this activity amounted to 32 people from various backgrounds, Brani villagers have a high awareness of the quality of residential buildings, as evidenced by the results of a positive response to the construction of housing in accordance with the regulations. Although the cost of building earthquake-friendly houses is 30% greater than ordinary houses, the community is enthusiastic and accepts the adoption of earthquake-friendly simple residential technology.

Abstract

PT XYZ is a company engaged in the pipe industry with various types of HDPE pipe products according to consumer needs. PT XYZ has problems with the BX-75 engine because it has a high breakdown value and is obtained from historical production data. The high breakdown caused the production process of the BX-75 engine to be hampered and the daily production target was reduced. To determine the effectiveness of the BX-75 engine, measurements using the Overall Equipment Effectiveness (OEE) method are needed. The research was conducted using the OEE method to identify whether it is in accordance with world class standards, if the OEE value is still low, a Six Big Losses analysis will be carried out from the pareto chart which will determine what losses affect the low OEE value and analyze the details of the causes of each fishbone diagram. The average OEE value on BX-75 machines in November-December 2022 was 78.86%. The result is still below 85% so six big losses analysis is still needed. There are two types of losses that dominate, namely downtime losses and setup & adjustment losses. Downtime losses have an average loss of 13.50% and setup losses have an average of 9.53%.

Abstract

Today's industrial competition encourages companies to continue to improve the quality of their products. However, the quality of the product itself is not only influenced by how the processes occur in the production line, but also related to a series of flows starting from the arrival of materials until the product is received by consumers. As happened at PT. X, the company wants to identify product quality problems and reduce the number of product defects because many defective products are found. To control product quality, a method is used to reduce product defects by using the New Seven Tools method. New Seven Tools is one of the quality control methods used to find and solve qualitative problems. By using the New Seven Tools method, several causes of problems were found and recommendations for improvements were appropriate for each problem. Based on the results of the analysis to find the causes of quality problems using the New Seven Tools method, it can be concluded that there are 8 types of defects with 3 main factors causing defects, namely operator error during workmanship, poor material quality, and lack of quality inspection
