Abstract

The purpose of this study is to find out the total time required to perform the QCL (Quality Control Line) Assembly thoroughly and the exact number of samples for each checking element. The collected data is used to calculate the standard time for each checking element, where the total time required exceeds the time available. The shortage of time has reached 122.204 minutes and when the number of samples is adjusted with MIL STD 105E and MIL STD 414 then the shortage of time reaches 403.918 minutes. The proposed improvements are the minimization of the frequency of inefficient work elements, changes in details of check for non-critical elements, and the use of support personnel. These improvements have a positive impact, i.e. there is a remaining time of 18.433 minutes of total time available.

Abstract

The purpose of this research is to analyze the feasibility of buying a packaging machine 1kg that will be done by PT. X. The analysis includes three aspect that is technical, work environment and financial. The analysis of technical aspect will be choosing which machine should PT. X buy, the analysis of this aspect using value assessment methods. There are two machine offered with different specification, based on analysis machine A has better value than machine B therefore PT. X should buy machine A. The work environment aspect will be analyzed of social impact for workers compared to government regulations. In this research work environment element that used is noise, based on observation the work environment in PT. X is appropriate with government regulation. Financial aspect is analyzed with three methods that is NPV, IRR, and payback period. The result is NPV Rp. 58.882.595,86, with an IRR 37.67% and payback period 2.09 years. It is concluded that buying a packaging machine 1 kg at PT. X is feasible based on three aspect that has been assessed.

Abstract

This research focuses on improve the sampling system and QC line performance review at PT. X. The data required for this research are standard weight data of component, weight standard per component lot, and observation time data owned by QC operator. This data will be processed to find out the number of samples in accordance with military standard and the number of labor shortages or time required. The number of samples corresponding to the military standard is 315 - 500 pcs / lot and the minus time is 4 hours. Suggestions can be given is to add labor to QC or by changing jobdesc from other division operators.

Abstract

The design of HACCP at PT X for animal feed is designed to identify the hazards present in the feed production process. This design also takes into account government regulations on the prohibition of the use of Antibiotic Growth Promoters. The method used in the design is Risk Assessment and FMEA. This method can identify the frequency and severity of hazards that can occur in the production process, the value and the risk level of the hazard. Hazards are categorized into four classes: low risk, moderate risk, high risk, dan very high risk. The result of the design is that there is no new danger due to the prohibition of the use of AGP. The hazards identified are significant not CCPs where hazards can be controlled with the OPRP Plan. Hazards that have the highest risk value is the water content is not standard in the pelletizing process with the risk value 6.

Abstract

Hapete is the best and most complete thread manufacturer in Indonesia. This company applies make to order production strategy.  This production strategy makes the Production Planning and Inventory Control (PPIC) Division, the one who make the production planning, must have the efficient planning strategy. The program that PPIC Division use this time doesn’t really efficient, because of the big memory of the used program. The use of macro and Visual Basic Application (VBA) will reduce the memory of the program. The analyzing that has been done is comparing the memory between the new program and the old program. The old simulation program has 4657 KB as its memory, while the new program has 558 KB as its memory. The old planning program has 7969 KB as its memory, while the new program has 297 KB as its memory. The old monitoring program has 2906 KB as its memory, while the new program has 101 KB as its memory. The guide book has been made for further development of the program, which will make the easier development process for the program.

Abstract

The raw material used for the production process, 70% comes from outsourcing. This high percentage is the main challenge for PT SEMB to control and ensure raw material is ready when needed. The consignment model has a minimum limit and a maximum limit. The material will be kept at PT SEMB, while not being used these raw materials still owned by the suppliers, and the place to keep this material is not registered as PT SEMB in the system. This means consignment material should have a low inventory level because the ownership will change only when the material is used, but the problem is from January to March 2019 inventory level consignment material has increased. One of the main problems is outdated information for material limits (min-max). This problem solved by making tools that can adjust materials limit (min-max) with the production process and at the same time, it's adjusted with the manpower to do the replenishment process at Lot 15. Improvement also made by changing the person who doing open consignment from leader Lot 15 to warehouse leader Sensor plant. The results for this improvement are decreasing average inventory levels from $362,221 (January-March 2019) to $240,327 (May 2019). Decreasing is approximately 33%

Abstract

Occupational health and safety is an important aspect to be considered by company, also in university. The academic community, which is active in the campus area cannot be separated from the risk of work accidents. This research was done at a private university that was established in Surabaya, East Java. With the extent of the area of the university, it can be possible to pose a potential hazard. Work accidents may occur because of the hazards that have not been identified at the campus area. Therefore, a Hazard Identification Risk Assessment and Risk Control (HIRARC) is needed to identify potential hazards at the campus area. Hazard identification is carried out to determine various potential hazards found at the campus area. After identifying the hazards, then it will carry out a risk assessment. The results of hazard identification and risk assessment at the campus area obtained 164 in the low risk category, 8 in the medium risk category, and 8 in the high risk categories. Every risk found will be carried out to risk control. Risk control will be controlled by means of elimination, substitution, administration, design, and use of personal protective equipment (PPE).

Abstract

PT X is an automotive company that operates as a manufacturer, assembler, and distributor in and outside the country. PT X is a subsidiary of a multinational company. PT X uses the Just In Time (JIT) principle, so it does not have inventory (zero inventory). PT X produces motorbikes that have a type and color type, where motorbikes produced will be distributed to 29 main dealers. Land distribution will use trucks provided by the transporters, where the trucks used will be regulated in accordance with government regulations. The regulation issued by the government regarding this matter is the rule of Over Dimension Overload (ODOL), where the regulation regulates the dimensions of the trucks used to transport goods. The use of dashboards is a solution to simplify the process of monitoring and controlling the condition of each truck at each main dealer. The use of dashboards for monitoring and control processes is more effective and efficient, because the dashboard can provide a lot of information through just one view. The use of the dashboard increases the progress of improvement, where in January 2019 only 63.13% to 76.55% in April 2019.

Abstract

This case study was done at a private university located in Surabaya. The aims of this study was to analyze the potential hazards and risks of workplace accidents. The university is preparing for the stage of the Occupational Health Safety Management System (SMK3). The Hazard Identification, Risk Assessment and Risk Control (HIRARC) method is adopted to detect activities on external parties and arrange for its control so that the potential for workplace accidents can be minimized. The design of HIRARC for external parties of university was 51 potenial hazards. This potential hazard has an extreme risk assessment value of 0% , high 24%, moderate 25% and low 51%. The proposed risk control for K3 induction such as guidebook and video safety induction. In addition, risk control is carried out by means of elimination, substitution, administration, and personal protective equipment.
