Abstract

This community service partner is the Non-Governmental Organization (NGO) PERMAI in Penang. PERMAI members are generally Indonesian workers who work in Penang, some of whom work as home-based food traders. Around where he lives, traders produce waste, including organic waste from cooking activities and leftovers from selling vegetables and fruit. This organic waste rots easily if left alone, causing an unpleasant odor in the surrounding area and causing a smelly and unhealthy environment. One way to handle organic waste, especially rotten fruit and vegetables produced from household or restaurant waste, is by making liquid fertilizer. The implementation method used is two stages, namely: 1) preparation stage; production originating from appropriate technological equipment activities for making liquid fertilizer, discussions and sharing with team members, and 2) the stage of implementing community service at partner locations, distributing questionnaires before and after the exposure. The expected target in this community service activity is to increase the knowledge of the Indonesian working community in Pulau Pinang regarding how to make and the benefits of liquid fertilizer which can be made from everyday household vegetable and fruit waste.

Abstract

The inventory system throughout the supply chain network must be effectively controlled, making Work in Process (WIP) inventory control essential. In tire manufacturing, Green Tire inventory holds the highest WIP value and is consistently maintained. However, inconsistent order quantities have resulted in uncontrolled inventory levels, leading to overstock in the storage area. This study aims to analyze the priority categories of Green Tire inventory, evaluate the optimal order quantities, and compare total inventory costs to minimize the overall cost. The methods used include ABC Analysis and Production Order Quantity (POQ) with safety stock, applying service levels of 93%, 90%, and 80% for A, B, and C categories, respectively. The findings indicate that Green Tire inventory class A accounts for 65% of the volume and 67% of the total inventory value, class B for 23% of the volume and 28% of the value, and class C for 11.9% of the volume and 5% of the value. Implementing the POQ method standardizes order quantities across rim codes, reducing maximum inventory levels by up to 69.38%. Total storage cost savings reached 66.15%, with only a 0.2% increase in setup costs. The POQ method achieved total inventory cost savings of 52.37% for Green Tire inventory.

Abstract

The shift towards renewable alternative energy has become a critical agenda for countries worldwide, including Indonesia. The Indonesian government has set a goal to reduce CO₂ emissions by 358 million tons, or 12.5% of the national emission reduction target by 2030. This study aims to design an efficient system for measuring the performance of the biodiesel supply chain in mining companies. The research methods used are the Analytical Hierarchy Process (AHP) and Supply Chain Operations Reference (SCOR) model. The SCOR model is used to create a process-based supply chain performance evaluation system, enabling companies to evaluate their supply chain activities comprehensively for monitoring, control, and communication of business goals to related functions and the supply chain. The SCOR model focuses on five dimensions: reliability, responsiveness, agility, cost, and asset management. As a structured process hierarchy, this model facilitates supply chain management and provides metrics to assess specific performance aspects in these SCOR dimensions. Initially, relevant Key Performance Indicators (KPIs) were validated using the SCOR framework, and the weighting of selected KPIs was carried out using the AHP method. Of the 42 initial indicators, 23 were selected. The results of the performance measurement for the biodiesel supply chain in mining companies showed that the highest SCOR values were for responsiveness and cost (1.00), followed by reliability (0.95), agility (0.88), and asset management (0.82).
