Abstract

Produk hasil pengolahan ikan, terutama ikan asap di Indonesia terus meningkat dari tahun ke tahun. Peningkatan jumlah produksi ikan asap ini harus diimbangi dengan peningkatan kualitasnya agar dapat bersaing di pasar bebas ASEAN (MEA). Selama ini produk ikan asap dalam negeri kurang begitu diminati oleh konsumen serta identic dengan tingkat higienitas dan aspek sanitasi yang kurang baik. Untuk itulah perlu dilakukan identifikasi terhadap kebutuhan konsumen ikan asap untuk dapat meningkatkan kualitasnya. salah satu caranya adalah dengan menggunakan metode QFD (Quality Function Deployment) yang selama ini telah sering digunakan. Dari hasil penelitian yang dilakukan, didapatkan hasil bahwa  variable yang paling fiinginkan dan dibutuhkan konsumen adalah kebersihan dan keamanan untuk dikonsumsi. Sedangkan untuk karakteristik teknis pada ikan asap yang perlu untuk dikembangkan lebih lanjut adalah sistem pengemasannya.

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.

Abstract

The design of the layout aims to optimize aspects of productivity, processing time, worker fatigue, cost & distance of movement of material on the production floor. Optimizations regarding material displacement distance typically focus on minimizing the distance between the production units within the manufacturing company. This study conducted a case study on UD Utama Tires which is one of the companies manufacturing retread tire trucks located in Semarang. The company has crossmovement related problems between production units and departmental layout that is not in line with the production process flow, while the availability of production space is only 30x15 meters and there are 12 departments. The observation result shows the distance of material transfer in the heat-processing unit is 111.96 m and the cold-processing unit is 100.63. Optimization needs to be done to minimize the material distance between the units of the process. Blocplan algorithm was chosen as the method of arranging the company layout and obtained the result of 20 alternative proposed new layout to then selected one of the proposals with the highest layout score. The result of this research is the 15th proposed alternative with the highest layout-score value is 0.82, so it can be concluded that the optimum model can minimize the distance of the material production movement by 63.8m in the heat-processing unit with the effectiveness rate 43.02% and 69.1m in the process unit cold with effectiveness rate 31,33%

Abstract

One form of actual problems in the manufacturing industry is how to maximize the value of profit with various constraints or constraints. The problem is not only experienced by big industry but also small industry like in UD. Wingko trip Mr. Moel who is trying to maximize the value of profit by estimating the amount of wingko trips that must be produced because there is a problem of the difference in the amount of production with one of the limits associated with the production capacity. The resulting production difference causes the amount of wingko trip or excess production in certain month. The method of Goal Programming is the one method of optimization with more than one objective that are interconnected with each other or conflicting to solve the problem. This research uses the Goal Programming method to optimize the production amount and maximize the profit of the product, and to forecast the number of forward demand by using the number of the past request to know how many products must be produced. Goal Programming Formulations use forecasting as decision variables for optimization of results in compliance with criteria and constraints. The results show the optimal amount of production in January - December 2017 are 29860 bag wingko original, 24000 bag wingko chocolate chocolate, 26004 bag wingko tripe jackfruit and 18084 bag wingko tripe durian with total profit in 2017 is Rp. 429.736.600.
