Abstract

PT. X is a subsidiary of PT Astra Otoparts engaged in the automotive industry in producing motorcycle chains, engine chains, filters, and accessories for motorbikes. PT. X has 2 customer chain products, namely OEM (Original Equipment Market) products which include Astra Honda Motor (AHM), Yamaha, Kawasaki, and Suzuki. RM Products (Replacement Market) which include Honda Genuine Part (HGP) and Yamaha Genuine Part (YGP). The chain of OEM products is a chain that will be installed directly on a motorcycle during the assembly process. The RM product chain is a spare parts chain that will be marketed in motorcycle dealers. Determining the standard time and production capacity of each process aims to determine the production lead time. Production lead time is needed by the company to determine a product from the start of the raw material being processed to the end of being a chain product. The results of the calculation of the standard time of each process can be analyzed as the cause of the delay in product distribution to the customer. The results of this study are used to determine the production lead time for a certain period with the number of stock components, the number of chain stocks used for production plans for a certain period. The production plan uses data from the calculation of the standard process time and process capacity used to determine the production lead time.

Abstract

PT. X is a company that engaged in the production and distribution of motorbikes. This research was conducted in the LDD department, where the department supports the distribution process of motorcycle at PT. X. The role of the LDD department is to ensure the distribution process of motorbikes, so that motorbikes can reach the hands of consumers well. The LDD Department expects a working system that is more effective, efficient, and transparent in monitoring so that units that are not unfilled are low. Problems will be identified by using fishbone diagrams, where the results of the identification are found to be three main problems that occurs in the LDD department. The main problem is the opening of DO is not in accordance with the capacity of the truck, the truck does not come to take up the DO units that have been opened, and the trucks that come cannot be carried out the loading process directly.

Abstract

This study discusses the design of a self-evaluation program with a media called e-filling for ISO 9001:2015. in this e-filling program, it is useful to help an organization create an internal management system faster, easier, and without having to sacrifice production time to prepare for ISO 9001:2015 certification. This e-filling program packs the concept of self-evaluation so that in the program there are various questions that are in accordance with the clauses in ISO 9001:2015 along with the assessment points. so that auditors no longer need to come to a company to audit the completeness of documents to meet the requirements of the ISO 9001:2015 clause. This program, also helps in the COVID-19 pandemic, where it is not recommended to have direct contact between humans, so with this program, auditors no longer need to have direct contact because everything is done online.

Abstract

Education is important because we will never stop learning both formally and informally. This is also supported by the government in Article 34, paragraphs (1) and (2) of Law no. 20 of 2003 concerning the National Education System. However, the government program cannot run without the role of the teacher because the teacher is not only tasked with teaching, but also to guide, train, etc. Therefore, it is important for teachers to have work engagement in order to carry out their work well. Especially during a pandemic, where there are changes in teaching procedures that require teachers to adapt and work extra to prepare teaching needs. With the increasing demands of work, gradually this will affect the work engagement of teachers. Therefore, it is important for teachers to have a calling, so that they consider that what they are doing is a service or dedication.

Abstract

Competition in the construction service industry rest on the company’s ability to provide service quality that satisfies customer expectations. Measurement of service quality with intangible characteristics can be done by measuring the level of customer satisfaction as an evaluation to improve service quality. Service quality is a method for measuring gap between customer perceptions and expectations of the service attributes. Evaluation of service quality are divided into five dimensions comprising of tangibles, reliability, responsiveness, assurances, and empathy. The negative value gap indicates that the customer satisfaction level is still less than the level of interest for the service attributes. The Quality Function Deployment (QFD) method will be used to translate and formulate service improvement strategies in efforts to reduce gaps that occur and improve customer satisfaction. This research is conducted using a chain analysis method consisting of three House of Quality levels to give more specific results for the company.
