Abstract

During this pandemic, many learning activities that were initially carried out face-to-face were replaced with online learning using applications. Several universities in Indonesia have started implementing online learning for students and lecturers from the odd semester of the 2020 academic year to the odd semester of 2021. The work on this final project uses the Technology Acceptance Model (TAM) method which is the method usually used in analyzing the acceptance of a new technology. This study is also used to determine the existence of several variables that will affect user decisions in the acceptance and use of the new technology. This research was conducted by distributing questionnaires to 152 students of a study program at a private university. After all the data has been collected, the researcher will analyze the data descriptively and test the hypotheses that have been made by testing using the Structural Equation Modeling (SEM) method to determine the influence relationship between indicators and latent variables. The results obtained from the study state that the results in this study are used to determine the factors that influence the acceptance of video conference by students of one of the study programs of a private university so that the results of this research can provide information on the results that can be used by the study program of a private university in knowing factors of student interest in online learning and maximizing the use of video conferencing.

Based on the measurement results, it is known that as many as 66.67% of inspectors in the EBM (Extrusion Blow Molding) area have an accuracy level that is below the company given standard. A root cause analysis was carried out to determine the root cause of the problem using the help of fishbone diagram. The root cause are dominated by the aspects of man and method. The results of the analysis will be used as a reference in improvement proposals, using the help of the design thinking method.

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. The improvements are made by digitizing the distribution process by Logistic 4.0 principle or designing the Transportation Management System (TMS). TMS is a system designed with the aim that the distribution process can be easily tracked and monitored. TMS will also connect related parties that previously sought manually. The distribution process is expected to be improved to be more effective, efficient and transparent

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.
