Evaluasi Keselamatan dan Kesehatan Kerja dengan Metode Job Safety Analysis
Get PDFPT. Laundry XYZ is a company engaged in the garment industry, especially in the field of color dye jeans. In the process of production of PT. Laundry XYZ found many potential hazards that could interfere with safety and health of workers. The potential danger caused by machines that do not operate properly and the chemicals used during the production process in PT. Laundry XYZ. Therefore, one needs to be done to eliminate the hazard control or prevent the occurrence of workplace accidents that could endanger the employees of PT. Laundry XYZ. In this study, researchers using Job Safety Analysis methods for controlling the potential hazard where data obtained from secondary data and primary data. Secondary data obtained through the company data, scientific books, and Internet media while the primary data obtained through the collection of results obtained from the questionnaire respondents employees at PT. Laundry XYZ. The method is conducted survey research that is applied, descriptive and qualitative. In this study will also be given a qualitative picture of the studied objects in the company. By performing Job Safety Analysis work on the production process in PT. Laundry XYZ is the potential danger that existed during the production process can be eliminated or controlled. The potential hazard can be controlled either by the method of technical, administrative and personal protective equipment (APD). In the process wringkled potential dangers can be controlled by modifying work tools, administration (working procedures), and provide personal protective equipment (APD) to the workers. In the washing process of the potential hazard can be controlled by modifying the working tool, the administration of the label by placing a K3 and provide protective equipment for work. In the process manequine potential dangers can be controlled by changing the way chemicals (substitution), modifying work tools, working with the administration put a label K3 and provide personal protective equipment. Results from the control of potential danger found a way or a solution to reduce the potential danger even so accidents can be prevented or eliminated. Development of Job Safety Analysis will get a new working method of an efficient and safe working on the production process at XYZ Laundry thus will improve safety and health of employees at PT. Laundry XYZ.Keywords: Keselamatan Kesehatan Kerja, Pengelolaan Limbah, Job Safety Analysi

Analisis Sistem Antrian pada Bengkel Mobil Menggunakan Simulasi
Get PDFIn this globalization era we are encouraged to do something with effectively and easily, because the time becomes an important thing in supporting the public activities. Companies should give a good service for customer without reducing its quality with an efficient cost consideration. Because of it the company should is obliged to reduce the queue so the queue will be more effective than before and will increas the customer satisfaction. This study uses a simulation analysis to determine the queue in actual system. This simulation requires primary and secondary data (observations) on every stall in car repair shop. The next step after we know the problem from the queue simulation is creating an improvement simulation to change the process in queue, and reducing or increasing the existing stall on the actual system. The result obtained from data processing and analysis, it was found some problems that happen in the real queue system such as full capacity on some stall. Stall that needed to be improve are Spooring Stall, External Service Stall, and Washing Stall. And then the next step is doing some improvement to change the process from SBEK and SBIK to Spooring Stall into Spooring Stall to SBEK and SBIK. The second improvement is adding SBE Stall and Spooring Stall by reducing 2 SBI Stall.The conclusion in this study are the increasing amount of the output, from first improvement it increases to 115 entities and from second improvement it increases to 143 entities. Then the total time of entities in the system decreased from 456.299,47 second into 310.597,57 second dan 359.925,65 second for each improvement.Keywords: Queue, Simulation, Operations researc
Analisis Kuantitatif Data Diffraksi Sinar X Fasa Keramik Crystoballite Berbasis Silika Sekam Padi dengan Metode Rietveld
Get PDFRietveld analysis is a means of revealing the detailed structure and composition of crystalline sample using x-ray powder diffraction data. This research presents the use of the Rietveld method using Rietica program to obtain the phase abundance of crystoballite crystal from rice husk sintered at 850oC, 950oC and 1100oC that has previously been demonstrated.The model parameters are refined by the methodof least squares until a good fit (2) to the observed data is obtained. The refined parameters in this study are background, scale factor, space groups, atom co-ordinates (U,V,W), preferred orientation, and the lattice parameters. The results showed that quantitative crystoballite crystal were 87.8, 89.8 and 98.4% weight, respectively. An acceptable result for estimation of lattice parameters and weightpercentage of crystoballite with reliability (2) was found to be < 4. The results also show that analysis by Rietveld method is efficient to control the quantity of crystoballite in the sintering process.Keywords: Rietveld, Rice Husk, X-Ray Diffractio

Analisis Persediaan untuk Menentukan Profit dan Tingkat Pelayanan dengan Metode Simulasi
Get PDFResearch analysis of inventory to determine profit and service level in company X with simulation methods is very important to be done to determine the average profit, minimum profit, maximum profit, and service levels with demand uncertainty, which will occur at the company X, which is located in Pegangsaan 2, Kelapa Gading Permai, North Jakarta. The research objective with this simulation method is useful in the near future to determine the possibility of profit that happens, and the service level provided to customers. The long-term goal is to teach the way of solving the problem in inventory in operations management, which is taught in management courses at Bunda Mulia University. Results of this study in operations management were adequate for the subject of inventory, as the company can only provide a service level of 85%. However, the company has gained an average excellent daily profit of Rp 26.474.673. The result can be more effective and efficient if the company uses a planning software to plan and calculate raw materials inventory to satisfy daily customer’s demand.Keywords: Inventory, Simulation, Average profi
