Abstract

This paper discusses the economic feasibility study of the project of procuring computer and tablet devices to companies as one part of the business in the paperless office. The purpose of this study is to analyze the feasibility of investment to increase productivity, reduce costs, improve site efficiency and reduce environmental impacts. Computer and tablet devices are used to reduce the cost of procuring documents which are usually carried out by the photocopy process and distributed to other departments. Measurement of investment feasibility using Cost and Benefit Ratio Analysis. The economic tools used in this investment feasibility study include Payback Period, Net Present Value (NPV), Return on Investment (ROI) dan Internal Rate of Return (IRR). The results of economic analysis using the cost benefit ratio method for the paperless office project are that the project deserves to be accepted.

Abstract

The availability of local rice needs to be predicted to meet the demand for rice supply in Indonesia. Central Java, as the third largest rice producer in Indonesia, is one of the pillars of national rice demand. The amount of food production in Indonesia is an important factor in determining the right food supply. Forecasting rice production in Central Java is necessary to determine future food conditions. The purpose of this research is to develop a forecast model for rice production in Central Java province and to find out the estimated rice production in Central Java Province in the next 5 years. The time series forecasting method was used in this study. The data used in this study are data on rice production from 1993 to 2020. From the results of the Auto Correlation Function (ACF) test, it is known that the production data has a trend data pattern. The method used in this study is the double exponential smoothing method with two parameters (Holt's Methods). The optimal forecasting model is obtained with the help of solver software in Microsoft Excel. By using the help of the Microsoft Excel solver, the optimal constant value α is 0,767 and β is 0,412 with a Mean Absolute Precentage Error value of 4,82%. Forecasting results from 2021 to 2025 are known to decline every year. The average decline in rice production in the next 5 years is estimated at 4,4% per year.

Abstract

Batik is an indigenous Indonesian product that is recognized worldwide. One way to preserve and develop batik culture is increasing the batik business productivity effectively, economically, and safely. Increasing the productivity of the batik industry can be realized by minimizing production costs. Reduction of operational costs can be done by designing the layout of the facility. Redesigning the layout and facilities is closely related to the design of the floor production as an object. Layout planning is a way of managing existing facilities on the production floor so that production can run smoothly. This study, aims to redesign the facilities on the floor production at SME Batik Natural Jarum so that they have a more efficient material flow. Arrangements are made for all work stations: raw material storage, production areas, and finishing areas. The purpose of this facility redesign is make the movement of materials run smoothly and reduced material handling costs. The method used in this research is Systematic Layout Planning (SLP). The results of the proposed layout redesign are a reduction in material handling distances and material handling costs by 8%.
