Abstract

PT Bangun Teknik Baja is a manufacturing company engaged in Fabrication, Repairing, and Machining for heavy mining equipment. The company does not yet have a basic strategy in carrying out inventory planning actions, so the amount of material ordered is only based on the estimated number of production product needs. Therefore, excessive amounts of inventory (overstock), lack of inventory (out of Stock) and frequent occurrence of Deadstock often occur. Order data, usage data and stock data on 50 types of fabrication materials with an average of 25 materials experiencing overstock, 4 materials out of stock and there are 221 Deadstock materials from August 2021 to July 2023 are used as the basis of this research. To determine the most suitable inventory control strategy according to the needs of PT Bangun Teknik Baja, processing is carried out with AHP, Music-3D with ABC, FSN and SDE Classification, and Min-Max Stock. AHP produces the most important priority classification dimension criteria, namely ABC, FSN and SDE with the most important sub-criteria being A,B,C,F,S,N,D,E,S. These results are used as a reference for Music-3D processing which produces 9 groups of material categories according to their respective characteristics of importance, namely AFD, AFE, ASE, BFE, BSE, CFD, CFE, CSD, and CSE, the 9 categories obtained their respective policy solutions by applying Min-Max Stock, by obtaining minimum and maximum limits on each material to minimize waste. ROP and Safety Stock calculations are used to minimize Overstock in minimizing Deadstock and Out Of Stock to minimize losses, so it is proven that the application of Min-Max Stock can save Total Inventory Cost by 1.45% from the company's actual policy.

Abstract

The aim of this research is to determine analysis for optimizing tape fermentation using a Temperature and Fermentation Controlled Chamber (TFCC) with a Hybrid System. The resulting numerical model was analyzed using a non-linear differential method using Runge-Kutta. The thing that was analyzed was the change in the rate of yeast concentration, the rate of change in the concentration of ethanol and glucose resulting from the fermentation process. TFCC with Hybrid System Technology is equipped with an automated system accompanied by sensors that detect food quality and can be directly observed through the LCD screen integrated in the device. The research method used is experimental research by designing a tool that can be used to produce/cook fermented foods while monitoring pH, alcohol, glucose levels and temperature levels which are integrated in a set of tools called the TFCC with Hybrid Systems Technology . From the numerical explanation, it can be seen that when t is small, the rate of yeast development in the fermentation process will be small, the number of yeast cells is still small. As a result, the growth rate will be slow. This can be seen from the graph of the increase in X(t) and P(t) as well as the graph of S(t) which is still slow. The greater the time t, the rate of yeast consumption is also greater because the number of yeast cells is also increasing. As a result, the growth rate of ethanol and sugar is also large. This can be seen from the graph of an increase in X(t) and P(t) as well as a graph of a faster decline in S(t). When the maximum consumption rate is reached, then the values of X(t), S(t) and P(t) are constant. The amount of concentration in the resulting ethanol is close to the initial concentration of sugar produced.

Abstract

The size of the material test specimen determines the accuracy of the material characteristics. This research was conducted to obtain the optimal tensile test specimen size by optimizing the cut parameters on the VZ-400 SA cutting machine. The material used is SNI 07-2054-2007 standard angled steel with a thickness of 5 mm. Optimization of machine parameters was carried out using the Taguchi method to measure the effect of work table speed (mm/s) and saw blade speed (m/min) on the response to the width of the rectangular cutting product. Cut width limit between 34-36 mm. Data was collected by conducting experiments 9 times with 3 replications. The results showed that the factor that most influenced the size of the width of the cut was the speed of the work table with a contribution of 86.49%, while the speed of the saw blade was 1.64% with an error of 11.87%. The optimal size of the test specimen is produced from the table speed parameter of 2 mm/s and the saw cutting speed of 90 m/min. Cutting validation was conducted in triplicate, and the result showed an average plate width of 34.7 mm with an error of 0.02.
