Abstract

Fish Production Center “Asap Indah” is one of the production centers in Demak, which specializes in processing fresh fish into semi-processed products, smoked fish. To support the sustainability of product distribution, supply chain management is needed to oversee the process from procurement of raw material to distribution to final consumers. Therefore, a comprehensive supply chain management analysis is necessary to increase sales and establish effective distribution channels. This research aims to understand the existing value chains of smoked manyung fish, the added value of each contributor on value chains, and to determine the most effective distribution channels of smoked manyung fish. The method used for data processing is descriptive-analytic SCM, Value Chain, and Value Added method. The result of this research, based on value-added calculation analysis using the Hayami method, shows fresh fish wholesalers give the least added value to the product or have the least amount of activities, so decreasing the unproductive activity to lower production cost is recommended. Value chain analysis shows that distribution channels or the most effective selling method of smoked fish are direct selling to the final consumer,accompanied by developing vacuum packaging to increase consumers’ interest in the product.

Abstract

The speed in distributing the products of the industry is influenced by the speed of production produced by the industry itself. SMEs know that ECO is one of the manufacturing industries engaged in food manufacturing. there are obstacles (problems) that are experienced, namely the occurrence of inequality between the production capacity of tofu that can be produced and the demand for tofu that must be met. The purpose of this study is to increase the production capacity of Tofu Eco SMEs in terms of increasing working time. The method used in this research is the dynamic system method using the PLE vensim software. The results of the study show that based on the actual system conditions, it is known that there are 25 workers with 8 working hours per day, and an average production capacity of 957 barrels per month is obtained month with an average demand of 1005 barrels /month. The results of the alternative simulation I, have an average production capacity of 1,080 barrels/month. The results of the scenario II simulation show that the average production capacity is 1,230 barrels/month. From the simulation results of alternative scenarios, it can be seen that for production demand below 1,080 barrels/month, the alternative used is to add 1 hour (60 minutes) of overtime, while for requests above 1,079 barrels/month with a maximum production demand of 1,255 barrels/month, alternative scenarios can be used. II with the addition of 2 hours 30 minutes (150 minutes) of overtime.

Abstract

One of the projects currently being undertaken by PT. XYZ is Dam “X”. Based on project management data obtained from PT. XYZ, the actual project construction process experienced a significant delay from the planned schedule, with a delay duration of approximately 30 days. The delay will have an impact on the duration of the final completion of the project, including the process of delivering project results to consumers. The purpose of this study is to determine the critical path in project implementation and identify activities that do not have slack time because it will affect the duration of the overall project completion. The method used in this study is the Critical Path Method (CPM), which is a network method consisting of a series of activity components with the longest total time and showing the fastest duration of project completion. The results showed that the Manufacturing Project has a total of 11 critical activities out of 37 activities (work packages), with a total critical time of 75 days. The total critical time from the calculation of the CPM method also shows the optimal total project duration which can be used as a reference for the project team for the completion of a fabrication project or a hydromechanical component installation project on Dam "X".

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.
