Abstract

Forecasting plays a crucial role in the decision-making process of any company or business organization. The aim of this study is to minimize potential losses through effective production planning. The study utilizes linear regression and exponential smoothing as forecasting methods. The results obtained from the study are specific to the cases in UD. Mustika Tip and it concludes that linear regression is the most effective prediction method. For cassava chips, the study reports a Mean Absolute Deviation (MAD) of 3,060.19 MAD, a method exponential smoothing (MSE) of 12,742,472.70, and a Mean Absolute Percentage Error (MAPE) of 0.52%. For yam chips, the MAD is 272.65, the MSE is 248,835.91, and the MAPE is 0.12%. Furthermore, the study recommends safety stock levels for both cassava chips and yam chips. The suggested safety stock for cassava chips is 211 kg, while for yam chips, it is 28 kg.

Abstract

A thermoelectric generator is an electrical generator device that converts heat energy into electricity directly based on the Seebeck effect method, namely if two different metals are connected at one end, then given a different temperature at the connection, there will be a voltage difference at the other end. with the other end, this study uses peltier tec-12706, the purpose of this study is to determine the effect of the temperature difference between the cold side and the hot side of the varied heatsink/fin designs. This thermoelectric component is coated by a thin ceramic that contains a bismuth telluride rod inside. When in supply the dc voltage is 12volt-15volt and the current is 2-5a. The cooling box material is covered with styrofoam, with a heat sink in the form of a heat sink fan. Variations are made on the amount of thermoelectric used. Data retrieval is done by installing a voltmeter, ammeter and thermocouple in a predetermined position then each measuring instrument will display the data. The data is then processed using the Microsoft Excel program which can produce graphs. With the form of a graph, discussion and conclusion can be done easily

Abstract

The cooler is one of the necessities for humans to store food, drinks, vegetables, fruit, meat and so on. Refrigeration systems that are commonly used today use refrigerants or freon/CFC (Chlor Fluoro Carbon) which are less environmentally friendly and expensive. To meet the need for cheap and environmentally friendly refrigerators, an alternative cooler is needed. One alternative refrigerant that has been widely used today is thermoelectric. The power source is from an adapter with an output voltage of 12V – 36V DC6A. Peltier Is a Thermo-Electric Module. This component is coated by a thin ceramic that contains Bismuth Telluride rods in it. When the DC supply voltage is 12volt-15volt and current is 2-5A. The cooling room material is Styrofoam, with a heat sink in the form of a heat sink fan. Variations are made on the amount of thermoelectric used. Data retrieval is done by installing a voltmeter, ammeter and thermocouple in a predetermined position then each measuring instrument will display the data. The data is then processed using the Microsoft Excel program which can produce graphs. With a graphic form, discussion and conclusion can be done easily.

Abstract

Solar power is an environmentally friendly renewable energy source. Solar power is utilized by solar power plants to generate electricity. The electrical energy produced is light energy which is converted by solar cells. A collection of solar cells arranged in such a way as to produce solar panels. The electrical energy produced will be stored in a medium called a battery. In the storage and use of this electrical energy, care must be taken to avoid overcharging/overcharging and over-using/over-discharging. Therefore, a battery charge controller is used which will regulate charging or energy consumption, besides that it also functions as a protection device. For the use of AC loads, an inverter is used to adjust the output voltage to VAC.
