Abstract

The electrical equipment industry in Indonesia is one of the factors that triggers economic growth. Labor productivity determines the success of project implementation. The non-optimal facility layout is one of the factors that triggers low labor productivity. The non-optimal facility layout affects the flow of information in the company. This study examines the problem of non-optimal office facility layout with TSP, ARC and ARD methods at PT. Duta Wijaya Elektrindo Engineering (PT. DWP). The method stated above can minimize the total distance traveled between office facilities so that work efficiency and workforce productivity may increase. The results of data processing indicate that the recommended office facility layout recommendations that are in accordance with the level of closeness between departments based on PST, ARC and ARD is the first recommendation. With reduced total distance traveled in the first layout of the proposed office facilities, the level of employee productivity and work efficiency will increase. The smallest total distance traveled on the proposed layout of the office facilities is 244.22 meters with a reduction of 36% from the initial conditions.

Abstract

The company discussed in this paper is a national distributor firm that distributes FMCG products. The PPIC division in the company is responsible for forecasting the demand using the combination of the moving average method and intuition according to the interest of the company. However, the PPIC staff never measures the accuracy of their forecasting method. This research paper aims to evaluate the forecasting methods used to predict the demands of 12 classes of A SKU. Four-time series forecasting methods are particularly implemented, i.e., ARIMA, moving average (MA), double exponential smoothing (DES), and linear regression (RL). Forecasting using the ARIMA method is carried out by considering the stationarity of the average and variance of the historical data points. Forecasting using DES is carried out by using the optimal alpha and gamma values of the ARIMA method. The results show that the performance of each forecasting method varies, depending on which demands of class A SKU are predicted. Based on these results, the current forecasting method utilized by the company should be improved using the time series forecasting methods leading to the smallest error values for each class of A SKU.

Abstract

Jaya Launch Pad is a company engaged in educational services. It is undeniable that service sector companies such as Jaya Launch Pad also have a workforce whose work posture may be less ergonomic, which can lead to musculoskeletal disorders. Musculoskeletal disorders can be experienced by people of all ages. Therefore, this study focuses on work posture. This research occurred because of complaints experienced by staff. The number of samples used in this study was 1 person. This was influenced by the Covid-19 pandemic situation so that there was only 1 staff when the observation was made. The research method used was the nordic body map (NBM) to determine which parts of the body are experiencing complaints, and the rapid office strain assessment (ROSA) to measure the risk of injury due to the posture of sitting at a computer for 8 hours. The result is that the complaint assessment using the NBM questionnaire has a score of 52 (needs improvement at a later date) with 4 categories of severe pain, namely back, waist, buttocks, and buttocks. Meanwhile, the score from the ROSA table is 6 which means it is risky / dangerous so that it needs improvement. Therefore, a proposed condition is given in the form of a replacement of work facilities in the form of a work chair with adjustable height and adjustable armrests. This improvement is assumed to be able to reduce the level of staff complaints, and the calculation result of the rapid office strain assessment (ROSA) is 4 which means no risk so that this improvement is accepted and can solve the work posture problem of staff at Jaya Launch Pad.

Abstract

ABSTRACT Analysis of the project implementation needs to be done so that deficiency andweaknesses can be identified, as well as problems encountered so that they can beused as reference material for subsequent projects. Project delays are often caused by lack of planned project activities and lack of control over the course of the project so that project implementation activities become less effective and efficient. The Critical Path Method (CPM) and PERT (Program Evaluation and Review Tecnique) are carried out to get an idea of what if the project is controlled by the two tools. Analysis of research results from the Remote Terminal Unit (RTU) project using the CPM method obtained a completion time of 104 days, while completion by the PERT method obtained time of 106.7 days with a probability of 99.99% completion and by processing the Fishbone Diagram there was a cause for the delay factor The biggest is the existence of material delays and the lack of supervision from the company. Keywords : Scheduling, CPM and PERT Methods, Fishbone Diagrams.

Abstract

This research aims to optimize the supply of raw material for nylon powder for the manufacturing industry. The problem was found in the nylon powder warehouse which was out of stock so that it had to be replaced with plastic raw materials to keep the production process running. The change of raw material from nylon powder to plasco was done because the company did not make an emergency order for nylon powder. This is due to the high cost of emergency orders. The use of plasco powder makes the company accept a sizeable return of goods. Therefore it is necessary to do a good inventory management to overcome the out of stock. The method used to solve this problem is the probabilistic P back order model. Demand in the previous period was normally distributed. The results of processing with the P back order model produce a service level of 99.95%. It is hoped that the company will not experience out of stock again. In addition, a savings of 4.50% were obtained from the total costs incurred by the company. Inventory policy obtained using the P back order model with an order time of (T) 0.358 or for 130 days a new order will be made, and the total inventory cost is Rp.418,363,268 / year with a service level of 99.995%.

Abstract

Human resources (HR) take an important role in a company to improve product quality. Human Resources in terms of the number of people and skills possessed are factors that influence the production of quality goods/products. Productive workers are workers who are able to produce products or services in accordance with the quality that has been set in a short time. The problem with PT.X in the packing section is that the packing target has not been achieved as set by the company. Another problem is the presence of manual loads above the standard load set. Meanwhile, packing workers also complained about the hot working conditions. So that further analysis is needed to determine the physical and mental workload on the packing work of PT. X uses Workload Analysis and NASA-TLX as well as analysis of the physical work environment (temperature and lighting). The workload and conditions of the physical work environment experienced by workers will affect worker productivity. The results obtained based on measurements using the Workload analysis (WLA) method showed that the physical workload of the three employees was high with a value of 121.97%, 119.20%, 117.81%. The results of measurements using NASA-TLX indicate that the mental workload experienced by packing workers is overloaded with values of 80.67, 82.67, 80 respectively. lux, both are within the normal threshold according to the Ministry of Health standards.
