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

Company X is a SME company that produced tempe, activity that is examined in the production process of Tempe is soybean washing activity, basket lifting and packaging. The purpose of this research is to determine the mental workload on the operators who carried out production activities. This research used the NASA-TLX method with the indicator of mental demand (MD), physical demand (PD), temporal demand (TD), performance (P), effort (E), and frustration level (FR). Data processing results show that soybean washing activity has a NASA-TLX score of 88, the basket lifting activity has a score of 88.67, and the packaging activity has a score of 90. The score shows that the workload on soybean washing activity, basket lifting, and packaging is very high for the operator. From these results, it is necessary to repair the working system so that the operator's mental workload can decrease so as to improve the operator's productivity and health.

Abstract

The increase in population and public awareness of the importance of animal protein have also caused increasion of animal protein consumption, especially beef. Therefore, it is necessary to increase beef production by increasing the livestock cattle. Cage condition plays an important role in increasing beef production. The better condition of the cowshed, the greater cow’s health will improve. The QFD method aims to design cowshed based on user desires by translating them into attribute forms. The criteria desired by users for the design of cowshed include: a) There is waste disposal; b) Using brick walls; c) Using wooden poles; d) The pen does not smell; e) Using an asbestos roof; f) There is good ventilation/air circulation; g) Simple shape; h) Individual pen model; and i) There is urine and feces processing. The design of cowshed that are in accordance with user desires include: a) There is a liquid waste drainage channel; b) There is a place for cow dung; c) The boundary wall in the pen is made of brick with a height of 100 cm; d) The poles in the pen are made of wood with a round shape; e) The slope of the floor is approximately 2 degrees so that the floor is dry; f) Using an asbestos roof; g) The design of a simple cage is as needed; h) There are food and drink containers for each cow; i) There is a place to tie but no divider for each cow; and j) There is a place to store liquid waste and a place for solid waste.
