Abstract

In this modern era, simulation software such as Arena has become a valuable tool for designing, optimizing, and analyzing the flow of supply chains efficiently. The aim of this research is to describe and analyze the flow of waste supply chains using Arena software. The second objective is to analyze the behavior of the people of Semarang city regarding organic waste processing using a macroergonomics approach. This study employs a simulation approach by utilizing Arena software to model the flow of waste supply chains from collection, sorting, processing, to final disposal stages. Using Arena software, simulation results can be measured and objectively analyzed, serving as a basis for identifying improvements and enhancements in the waste supply chain. To manage organic waste in an area it is necessary to involve cognitive, psychological, organizational and environmental aspects. The strategy for managing organic waste in urban areas such as the Semarang area is to manage and ensure that organic waste has added value and sales value.

Abstract

National Waste Management Information System shows that the amount of waste handled in Semarang City over the last three years has decreased with an average decline index of 1.06% per year. This is reinforced by the results of interviews with the Semarang City Environmental Service, that the handling of organic waste is still very limited because so far the handling has been more focused on an-organic waste. Therefore, it is necessary to evaluate supply chain performance to determine the constraints in organic waste management from upstream to downstream. Based on the research results using the Interpretive Structural Modeling (ISM) method through a focus group discussion process involving eight experts in the field of waste management, it is known that the supply chain performance for handling organic waste in Semarang City has 11 elements of constraints, which are divided into seven priority levels. The element with the highest priority is related to the availability of organic waste supplies, while the element with the lowest priority is technological innovation and the application of appropriate technology. Improving the performance of organic waste management supply chains should focus on elements according to priority.

Abstract

Saramanta Homemade located in Boja, Kendal is an MSME that produces various cakes. In its production, Saramanta Homemade experiences several obstacles, namely: less than optimal layout; work is done without a work desk, which affects worker he alth and reduces productivity; and decreased profits due to increased costs due to the supply of raw materials. In previous studies, productivity optimization was only focused on layout planning, while this study discusses measuring supply chain performance to increase profits and product design to implementation of designed products. Therefore, researchers use the EFD, SLP, and SCOR methods to solve these problems. The EFD method is used to design an ergonomic work desk with dimensions l = 1610mm, w = 710mm, and h = 1020mm so that it can reduce musculoskeletal complaints as evidenced by a RULA value of 2. The SLP method is used for changing positions between departments, shortening the moving distance by 71%, the total moving time by 50%, and OMH by 47% so that the layout can be optimized through the proposed layout design using Blocplan software. SCM performance measurement with SCOR of 63.83% (average). As well as alternative proposals for selecting suppliers from Semarang, shipping costs of Rp50,000, Emina cheese brand of Rp45,000/kg, and the addition of 4 workers so that expenses are reduced by 5.8%, profits increase by 58.1%, and cash-to-cash cycle time becomes 31% shorter.
