Abstract

PT SEMB is a company that works in the production of electrical components related to energy management and automation. The problem that occurs is the order made in the present conditions is still not optimal, causing the inventory level to be high. The study was conducted to help the company to be able to reduce the inventory costs and transportation costs. Direct delivery is a system that helps to reduce the inventory level and cost to the cost of goods ordered. The simulation that has been done for direct system can provide savings of up to 50,000 USD. Savings obtained from this direct system if applied to all local suppliers will reduce the cost of 280,000 USD compared to the current conditions. In addition, milk-run studies are also used to material pick-up methods. This method can also reduce the transportation costs until 900 USD.

Abstract

The X Corporation is a shipping logistic company established in 1984 and headquartered in Surabaya. Based on X Corporation's business model, containers are inspected and repaired first after used by customers. Thus, shipping container repaired work data are recorded and used for our study. MTBF (Mean Time Between Failure) and other important parameters that indicate the shipping containers' performance and reliability are post-processed and analyzed in this study using data mining method. The post-processed data are visualized using dashboard to make it easier to monitored in a glance. In short, the data visualization dashboard (in this study) depicts the post-processed data of damaged containers, repair works, MTBF value, types of damage, location of damage, types of repair, supplies of the component, and other parameters. Therefore, the dashboard is expected to help the companies in making decisions to improve container reliability based on MTBF values and other data that affect container reliability.

Abstract

Fierce competition in winning consumers on the sale of polyethylene-based products causes PT. X has to continuously update the ISO 14001:2015 environmental management system certification. PT. X strives to maintain the implementation of the environmental management system, therefore an analysis of the application of the ISO 14001: 2015 environmental management system is carried out. It aims to obtain the degree of conformity between the actual conditions in pt. X with existing standards in the ISO 14001:2015 environmental management system and found a draft of improvements to improve the level of conformity. The methods used in this study are filling in iso 14001: 2015 checklists, calculating the percentage of the degree of conformity with the gap analysis method, root cause analysis with the five why method and fish-bone diagram. The results of this study are an improvement design that is expected to be useful by PT. X to meet the requirements for renewal of ISO 14001:2015 environmental management system certification.

Abstract

This research was conducted to provide new innovations in the learning process activities of the Supply Chain Management course. By using simulation games, the learning process will run more interestingly so it is hoped that the knowledge taught can be absorbed by students optimally. The risk pooling material is one of many materials whose teaching will be more optimal with the existence of simulation games. This method compares the decentralized and centralized supply chain systems. In decentralized supply chain there are 3 stages and in centralized supply chain there are 2 stages. The simulation game was created using the AnyLogic application. The result of this research is in the form of a simulation game that describes a decentralized and centralized supply chain system.

Abstract

The purpose of this final project is to design the control of the spread of the corona virus in the classroom. The method used is descriptive research, literature study and extracting protocol information from various literatures. The control design consists of several stages, namely seeking information through literature studies to identify potential points of exposure to COVID-19 in the classroom, identifying causes of failure, identifying the impact or risk of failure. After identifying new problems, an assessment stage is carried out to look for possible impacts or risks so that a control design will be made as a solution. The results show that there are 9 controls that will be designed to control the spread of COVID-19 in classrooms and the final result of this final project produces suggestions for protocol stages according to government standards and universities or schools that have carried out offline learning in the new normal period.

Abstract

The study was conducted at a plastic ore company. Problems obtained from observations and interviews, namely complaints in the skeletal muscle operator. The purpose of the research is to prevent the occurrence of complaints of musculoskeletal disorders. The Nordic Body Map questionnaire and disease history are distributed to determine complaints that are often experienced by operators. The Wilcoxon Signed Rank Test is used to compare the results of the Nordic Body Map questionnaire before and after work. Proposed improvements are made to each activity that affects skeletal muscle complaints that are often experienced by operators. The proposals given are moving raw material storage near the stage stairs, implementing work rotation, adding 1 operator, and applying manual lifting with the principle of ergonomics. In addition there is also the design of work facilities in the form of footrests and redesigning plastic ore storage tanks.

Abstract

PT. X is a company that has long been engaged in the glass manufacturing business and has several production plants. One of the plants of PT. X., which produces industrial glass have been had delivery lateness around 57% of all orders that have been received during January to May 2021. One of the factors that made lateness in delivery was came from the lack ability from Production Department to fulfil orders because the schedule for each machine did not made regularly. This research wishes to be able to give a scheduling improvement that can lower the rate of delivery lateness. The actual scheduling condition in that plant is done by manually moving the prioritized items  with Microsoft Excel program. This research will discuss the proposed Flexible Flowshop scheduling using Microsoft Excel VBA program with the objective function of minimizing the total weighted number of tardy jobs. The results of the proposed scheduling with the Microsoft Excel VBA program have a 25% better solution than the actual method. In addition, this method can shorten the working time of PPIC staff in generating scheduling for each machine.
