Abstract

Fraud of fake halal label products does not open halal production processes about the supply chain from upstream to downstream. Therefore, in product integrity agreements, it is necessary to implement traceability in the food supply chain as an effective tool in ensuring product halalness and ensuring food products are safe. Therefore, this study tries to make a model of halal Supply Chain Traceability in the integrity agreement of halal food products. The method used in modeling the halal supply chain traceability system using Interpretive Structural Modeling (ISM). Elements of a halal supply chain tracking system, in addition to halal procurement, halal manufacturing, halal logistics, halal distribution, supplier traceability, producer traceability, logistics traceability, distribution traceability. ISM Modeling results in the integration of halal products are located in Quadran IV Driver Power with halal manufacturing, producer traceability, supplier traceability, Quadran III Strong-Very Driver Depends on Variables (Linkage), Traceability system elements of the halal supply chain that are in accordance with this Quadran will be sought integrity of halal products and has strong advantages as a driver, this quadrant contains halal procurement, traceability distribution, halal logistics. Whereas the halal supply chain traceability system that is not related to the integrity of halal products comes in. Quadran II Driver Power namely: halal logistics and distribution traceability.

Abstract

Self-Estimated Price (HPS) is an assumed cost for the procurement of goods and services in accordance with predetermined provisions and sourced from accountable data. In the field of procurement PT. PJB UP Paiton Unit 1&2 still has several errors in determining the HPS which can result in a failed auction. This study uses simple statistical techniques and also uses the Statistical Product and Service Solutions (SPSS) application so that the price intervals used are maximum HPS and minimum HPS. The price interval is the lowest and highest price limits used as the basis for determining the price of goods and services. In determining the HPS in the procurement of goods and services PT. PJB UP Paiton, calculates the HPS using an operational budget that uses five data sources in its determination. Data sources used in determining the HPS are market price data, previous contact prices, target price proposal prices and comparative study prices. The results of the HPS calculation for the procurement of 500 work vests, so that a minimum HPS of Rp. 52,250,000 and a maximum HPS of Rp. 56,080,200. In addition, the authors calculated the procurement of panel wall installation services with a size of 2.5 x 10 meters, so that a minimum HPS of Rp. 9,761,345 and a maximum HPS of Rp. 9,996,250.

Abstract

This research applies the application of delivery consolidation in the context of a multi-product and multi-echelon food supply chain, as a strategy to address operational efficiency and cost management. The aim is to implement consolidation in multi-product and multi-echelon distribution systems, in order to optimize product placement and distribution efficiently. The method adopted is the Linear Programming model, which considers key variables such as the number of goods to be sent, delivery route, resource allocation, fleet capacity and delivery time limit. The research results show that shipment consolidation, by scheduling shipments that are delayed until the second or third day, allows combining orders into one large shipment, thereby increasing load and route efficiency, reducing trip frequency, and achieving significant transportation cost savings. This strategy successfully increased load and route efficiency, reduced the number of trips required, and resulted in substantial transportation cost savings. Using this method, the total shipping and storage costs are 1,328,834. This consolidation strategy has proven crucial in optimizing delivery types, in addition to facilitating more effective route planning, reducing travel distances and times, and resulting in significant operational cost savings.
