Abstract

Occupational health is an important aspect to be considered by company. Workers, while producing food, cannot be separated from risk of getting occupational diseases. This company wants to implement ‘Zero Diseases’ program and requires documented monitoring and relevant control methods for occupational diseases arising from work activities. Assessing a Health Risk Assessment might be considered the most appropriate way to answer the company’s need related to documenting types, risks categories, and appropriate control methods of related occupational diseases. The method used in data collection is direct interviews, questionnaires, and annual employee’s health monitoring data from the company. The data is processed according to the needs of each type of occupational diseases. The risk categories are grouped based on a risk matrix. Sums up low risk occupational diseases as much as 59%, medium risk as much as 37%, and high risk as much as 4%. Control methods are included and adjusted to the types of occupational diseases and based on the principal of hierarchy of controls. All types of occupational diseases have administrative controls, eight of them have Personal Protective Equipmemt (PPE), and one of them has engineering controls.

Abstract

Logistics is a business that will continue to grow, because it is needed in the business world to deliver goods at the right time and quantity, and at low costs. PT. X is a logistics and shipping company. One of the activities that run in the logistics and shipping business is container haualge. The haulage process is considered still less effective and efficient. The current level of productivity as measured by the number of ritase per day is low. This is caused by the haulage process that can not be detected in real time, impractical communication media, queues, and unavailability of trucks. The trucking haulage application is created and developed so non-value added activities will be minimized or eliminated, so the haulage productivity dan be increased. This study discusses the development of a trucking haulage application in phase 1.1. The implementation result of the application shows that the haulage productivity increased from 7,36 ritases per day to 7,93 ritases per day. Two sample t-test shows that the p-value obtained is 0,033 (< 0,05), so it can be concluded that the trucking haulage application can increase the productivity of container discharge at PT. X Surabaya.

Abstract

PT X is a circuit breaker company that produces various types of products. There are several production segments and each segment are used to produce one product type. PT X has conducted an evaluation of the facility layout in segment I, and found the need to improve the facility layout. Shortcomings of the current layout are the arrangement of several facilities, which located outside of the available area for segment I. The arrangement of new production layout, however, should not reduce production output. Production facility re-layout is costly; therefore, simulation is used to analyze the proposed layout. Simulation approach is used to compare the initial layout against the proposed layout. The simulation model was built using Promodel 10 software, with a simulation time of 22.5 hours and replicated for 25 times. The proposed layout is derived using an evolutionary algorithm method, with adjustment in respect to some constraints from the initial layout. The proposed layout can answer the needs of segment I, because there are no facilities that exceed the specified area and result in more products in a day than the initial model.

Abstract

The research conducted in logistics company that provides door to door delivery services. This company is expanding the consolidator building where the goods handling process is carried out. Along with the expansion of the consolidator, company wants to design a sorting room layout that can minimize the occurrence of missroute goods and increase the effectiveness of the process at the consolidator. Company also wants to evaluate the needs of its operational and administrative workforce. The design of the consolidator layout is done by taking into account the number of destinations of the sorting room, the amount of aisle needed, and the amount of sorting space based on the volume of goods. The layout design produces 3 sorting areas with a total of 115 sorting rooms. Evaluation of workforce needs is done by work sampling and calculation of full time equivalent. The determination of operational workforce needs is then followed up with a process simulation with the help of standard time calculations. The result of the calculation is to reduce 3 workers who are projected to be able to reduce labor cost by IDR 100.811.501,- annually for the company.
