Abstract

PT IJS is a company engaged in logistics services in the Perak area of ​​Surabaya. PT IJS was founded in 1984 when the need for container depots was urgently needed around the Tanjung Tanjung port area to unravel the shipping queues and shorten licensing. One of the services provided by PT IJS is bounded warehouse rental services. Bounded warehouse owned by PT IJS is currently not able to provide maximum service because there are still many late deliveries which do not result in the sending of goods to the port and there is a closing time that is detrimental to the customer. The length of the delivery process is due to several factors, one of which is a less effective company layout. Travel time is the time required for a vehicle to carry out goods loading activities at PT. IJS from arrival to exit company. Based on travel time calculations when using the initial layout, the travel time value of T = 2002 seconds. The weighted-distance method is a mathematical model used to evaluate the layout based on proximity factors. The design of the relayout design using the weighted-distance method produces alternative layouts that produce shorter travel time calculations, alternative layout with T = 1849 seconds.

Abstract

there is a previous study analyzing the design of ergonomic chairs for pond machine operators, where the analysis uses the RULA method manually, Based on the results of data processing with the RULA method, it can be concluded that the posture of the ring making operator (washer) operator with a slightly bent body position has a score value 5, and the chair design based on the redesign of the pond engine operator chair shows that the final result is 3. (Mukhtar, 2018) In this study, a productivity analysis is carried out to measure the level of chair productivity by considering several aspects of work activities, The method used is the Objective Matrix (OMAX) and the determination of the score from the performance appraisal using the Analytical Hierarchy Process (AHP) method. The results obtained are Productivity increased from before, because it is still in the range of 3-10 (based on the matrix table the score 3-5 is good enough, 6-8 good and 9-10 very good) and the lowest values ​​shown in this table are 3 and 4 Based on the scores, the scores are still quite good. But there still must be improvement. Overall the level of productivity has increased compared to before. But there are still fluctuating data. This is due to the lack of uniformity in the ability of the opeator to run the pond engine in washer production.

Abstract

At present the use of wind energy in Indonesia is still relatively low, but has enormous potential. One reason is because the average wind speed in the territory of Indonesia is classified as low wind speed, which ranges from 3 m / s to 5 m / s making it difficult to produce electrical energy on a large scale. However, the wind potential in Indonesia is available almost all year long, making it possible to develop small-scale power generation systems. Innovations in modifying windmills need to be developed so that in conditions of low wind speeds can produce electrical energy. In this research, a prototype was developed by designing a vertical axis windmill power plant model Savonius using a permanent magnet generator, which can produce optimal electrical energy by utilizing relatively low wind speeds.From the generator test it was found that with a rotor rotation of 50 rpm up to 500 rpm can produce an electrical voltage of 0.02V to 10V and an electric current of 0.60A to 4.53A.
