Abstract

In the current electricity development project, the understanding of OSH does not seem to be fully implemented. One indication that the knowledge of OSH has not been fully implemented is that workers are still unaware of the hazards associated with their work. Based on these issues, the question is whether intrinsic factors (motivation) and extrinsic factors (hygiene) influence job satisfaction and worker performance in achieving zero accidents. This research will focus on how the measurement model can influence the OHS maturity level and what design strategies will be used to improve the OHS maturity level performance. This research aims to obtain a measurement model that can influence the OHS Maturity Level and provide a design strategy used to improve the OHS Maturity Level. The author uses quantitative methods and collects data from 516 PT PLN (Persero) UIP Nusa Tenggara Working Partners correspondents. Data testing methods include the measurement model test, structural equation model test, model accuracy test (goodness of fit), and hypothesis test. The results showed that job satisfaction variables, directly and indirectly, affect K3 Maturity Level performance. Therefore, a programme design is needed to maintain the K3 Maturity Level performance results and increase the value of the current K3 Maturity Level performance results. Policy-based programmes and communication-based programmes are the programme designs. These two programs aim to maintain and improve the value of the OHS Maturity Level performance. Keywords:hygiene factors, motivational factors, job satisfaction, OHS maturity level performance

Abstract

Movement generation modelling estimates the amount of movement generated from the origin zone and attracted to the destination zone. The research aims to distribute the movement of passengers and vehicles for Ferries in North Maluku Province using the Detroit method in 7 movement distribution zones (Bastiong, Sidangoli, Rum, Sofifi, Batang Dua, Makian, and Moti). To find the distribution of ferries, the Geometric Method is used, where the value of r (growth ratio) is used as the growth factor (E) and the calculation of the distribution of movements uses the Detroit Method. The largest distribution of passengers is in the origin zone, namely Bastiong (movement 204577), in the destination zone, namely Sidangoli (movement 190621). The smallest distribution of passengers is in the origin zone, namely Batang Dua (movement 297), in the destination zone, namely Batang Dua (movement of 415). The largest distribution of vehicles is in the origin zone, namely Bastiong (movement 74828), and in the destination zone, namely Sofifi (movement 72057) and the distribution the smallest vehicle in the origin zone is Batang Dua (movement 97), and in the destination zone is Batang Dua (movement 101).

Abstract

Workload can be defined as the difference between a worker's ability and job demands. Based on observations that have been made, it is known that madukismo sugar companies get an increasing demand value in each season of production, so this causes an increase in the number of working hours that apply to the company, which has the potential to increase their mental work. This study investigated the mechanical mental workload of workers at Madukismo Sugar Company using the NASA-TLX method, a multidimensional assessment tool. The NASA-TLX method is a multidimensional assessment method that can measure the overall mental workload to determine the mental workload felt by each worker. The results indicate a very high mental workload in some operators and suggest the need for operational adjustments. The recommendations are additional manpower and improved ergonomic levels to reduce stress and increase productivity. Keywords: Mental Workload, NASA-TLX, Job Demands

Abstract

The increasing population has an impact on limited land, especially boarding houses for students. The room size for residential boarding houses is limited so that supporting facilities such as tables and chairs are readjusted. Lesehan tables are often used as furniture options for most student boarding houses, due to their simple shape and affordable prices. However, this is not supported by the ability of the lesehan table to accommodate the ergonomic needs of the user's sitting, which if it lasts long and repetitive will result in musculoskeletal disorder. Therefore, the design of ergonomic lesehan chairs is needed for student productivity and health. The research method used is a mix method starting with direct observation of boarding houses around Bandung, literacy studies related to ergonomics, anthropometry and sitting on the floor. The design method is UCD where the user's problems are solved by prioritizing their needs. The results obtained with this design can reduce pain in several parts of the body, can support student learning productivity and to minimize musculoskeletal disorder.

Abstract

PT BCD is one of the large pharmaceutical companies in Bandung, West Java which plays the role of main distributor. PT BCD is facing a problem related to its company logistics. The problem in question is in the form of customer complaints that reflect a bad image for the company, especially regarding on-time delivery. Many of these complaints came from outlets in the central rayon area consisting of RS A, RS B, RS C, Pharmacy D, Pharmacy E, Pharmacy F, PBF G, PBF H, and PBF I. In an effort to overcome this problem, the management plans to launch a program called same-day delivery service so it is necessary to carry out research that integrates the saving matrix method to determine the most optimal distribution route for pharmaceutical products so that the distance traveled in delivery is the shortest as well as carrying out mathematical considerations regarding fleet investment decisions based on which offers are available. Provides the greatest savings using the total cost of ownership (TCO) net present value method approach. From the results of the analysis of the two integrated methods, a picture of the decision in the form of the most optimal route based on the saving matrix analysis is obtained, namely PT BCD – RS A – RS B – PBF G – PBF H – PBF I – Apotek F – RS C – Apotek E – Apotek D – PT BCD with the decision to procure a fleet in the form of purchasing an L300 type box car. Keywords: Logistic, Net Present Value, Same Day Delivery, Saving Matrix

Abstract

PT BSB is a company engaged in construction specialising in steel fabrication. There are various projects carried out at the company, namely bridges, steel structures, buildings, towers, and others. The research was conducted to analyse the quality of results in the painting process at PT BSB using statistical quality control (SQC) and failure mode effect analysis (FMEA) methods. Data collection is done by collecting primary and secondary data used in this study. The four types of painting defects obtained from the research results are Sagging/Runs, Orange Peel, Pin Hole and Seeds/Dirt. Based on the FMEA method, the level of defects can be determined based on the cumulative percentage value produced, where the highest defect value is 1750 Sagging/Runs defects. One of the factors causing the defect is the uneven spraying of paint, causing a layer of paint that is too thick, resulting in excessive accumulation of paint in certain parts that flow vertically and unevenly. From this research, it can be concluded that the company must use the SQC method to determine the causes of defects in the painting process and analyse improvements that must be prioritised. Keywords: Failure Mode Effect Analysis (FMEA), Painting Process Analysis, Statistical Quality Control (SQC)
