Abstract

Abstract The supply chain is a network system of several interconnected organizations with the same goal of distributing production goods and services to their customers. PT. Samudera Gemilang Plastindo (PT SGP) is a company engaged in the processing of plastic seeds, one of the products produced is HDPE T-Shirt Bag. The supply chain system studied at PT. SGP consists of a Manufacturing (Vendor) and 3 Sales Offices (SIM Jember, Depo Bali and 3S Bogor) because they often experience inaccuracies in forecasting data which causes the Bullwhip Effect phenomenon or information distortion to meet customer needs. Initially, forecasting was carried out at each level of the supply chain using different forecasting methods and inventory planning was carried out separately and not coordinated with each other. Therefore, we need an equation in choosing a forecasting method to synchronize the forecasting results and the implementation of production in each supply chain actor. This study uses the Collaborative Planning and Replenishment (CPFR) method, which is a method that combines production planning, forecasting and inventory control. The results of testing several forecasting methods, the method chosen is the Winter's Method because it has the smallest error value. Inventory control is done by calculating the optimal lot, namely Economic Order Quantity (EOQ). The results of demand forecasting and determining the optimal lot are used to calculate the value of the Bullwhip Effect that occurs after the use of the CPFR approach in the supply chain at the vendor level (PT SGP) has changed from 1.285 to 0.729, while in the three Sales Offices there has been a change from 1.321 to 0.528 in SIM Jember sales office, 1.266 to 0.602 at Bali Depo sales office, 1.377 to 0.412 at 3S Bogor sales office.

Abstract

Abstract PT. XYZ is a private sugar factory in Lamongan Regency, East Java. The resulting product is sugar, besides that the sugar production process cannot be separated from liquid waste. PT. XYZ often has problems in the treatment of WWTP (Wastewater Treatment Plant) at the input in the BE pond (Equalization Tank). Influent in the BE pond (Equalization Tank) often occurs levels of COD (Chemical Oxygen Demand) that do not match the company's quality standards because the influent input is sometimes too large. The purpose of this study was to improve the quality of the influent product to match the company's quality standards with aspects of activated sludge utilization in BE ponds (Equalization Tank). The taguchi method is used as a method to improve and improve quality and analyze the factors that influence the quality of the influent, including the volume of activated sludge, the length of the aerator running, the volume of waste, the interval between activated sludge added and observed. Taguchi standard orthogonal matrix L8(27) used the objective function 'the value is getting smaller (closer to the desired 0)'. The results of the analysis of variance (ANOVA) obtained that the dominant factor affecting the quality of the influent was the volume of waste (C), while based on the Taguchi method, the most optimal experimental results resulted in a combination of 100 ml activated sludge volume, 5 hours aerator running time, 1 liter waste volume, the gap between activated sludge was added and observed for 5 hours.

Abstract

Industrial engineering is an engineering field that includes the knowledge of design, repair, and manufacture integrated systems consisting of people, raw materials, information, equipment, and energy. The laboratory is used to complete the observed research, especially industrial problems in the industrial engineering department. Based on previous research, as many as 62.5% of lecturers found it difficult to store laboratory equipment in the workspace and 81.25% suggested to rearrange the layout of the laboratory. This study aimed to design the layout of laboratory equipment by using the 5S method. The first step to do the research was reducing laboratory activities, initial identifying of laboratory layouts, grouping the machines and tools, designing the laboratory layouts, implementing 5S, and evaluating new designs by using the Self-Assessment Form. The resulting layout is in accordance with the 5S principle, the design of the wardrobe is relatively small, and the design adapts to the space and equipment stored. The results then showed that 5S performance data in the laboratory before the implementation was 0.71 which in the fair rating category, and after the application of 5S the average score becomes 1.5 which in the excellent rating category. However, it shows that there is two-fold increase before the implementation 5S method.
