Abstract

PT. APIE Indo Karunia produces is a casting company that produces steel and ironpart such as gear. The casting processes include material melting, mold making process usingsilica sand, moldcoating process, and pouring the melted metal into the mold. These processesuse a huge amount of energy that affect to environment. Thus, the calculation of eco-efficiencyratio for PT. APIE Indo Karunia is needed.The eco-efficiency ratio in months February, March and April are 1,06, 1,15 and 1,09respectively. While, the eco-efficiency of the total production on energy consumption are 1,22, 1,2and 1,226. These values are higher than the Indonesian energy eco-efficiency which valued 0,46.It means that the production process of PT. APIE Indo Karunia is still inefficient in terms ofenergy consumption .

Abstract

This article discuss about correlation between demographic factor of employees and work environment against potential disease suffered by employees. Demographic factor of employees such as job grade, age, weight, and blood pressure. The company wanted to know about description of potential disease suffered by employees based on demographic factor, the correlation between that variables, and know work environment factor which potentially against disease in workplace. Analysis method used Spearman’s Rho Test, Logistic Regression, and Fishbone Diagram. The higher demographic factor cause the disease suffered by employees more dominated by degenerative disease. All demographic factor have a correlation with potential disease suffered by employees, but only 13 from 24 disease have strong correlation. The potential disease suffered by employees also caused by 2 factors from work environment, namely man (employees awareness still lacking) and management (role of company not optimal). This research was ended by doing effectiveness of annual medical check up analysis, namely by eliminating blood glucose test and add USG mammae test. The company should give further attention to employees, such as give a punishment to employees who not wearing PPE, auditing SHE in workspace, improve the infrastructure and provide training for employees about SHE.

Abstract

PT. X is one of company that concerns with continuous improvement.  PT. X attempts to apply the concept of lean manufacturing in order to identify waste. Value stream mapping is one of the tools from lean manufacturing that can illustrate the entire process and identify waste ranging from the arrival of raw materials to the delivery of finished goods. Value stream mapping will be carried out at PT. X for department A. Through the current state value stream mapping can be seen that there are some waste in PT. X for department A ranging from the arrival of raw materials to become finished goods, among others is waste motion, over-processing waste, defect waste, inventory waste, and waste waiting. Design of future state value stream mapping is based on the proposed improvement given to the company. Future state value stream mapping can reduce lead time 41% from the current state value stream mapping.

Abstract

PT X is a company which produces vegetable oil with copra and Crude Palm Oil (CPO) as the raw material. PT X wants to supply international company, such as Kraft Foods. Kraft Foods has several regulations for prospective suppliers and of them is HACCP documentation. The design of HACCP system in this thesis is done for RBD (Refined Bleached Deodorized) CNO (Coconut Oil), Olein, and Stearin which produced at Plant 2 PT X. The first Critical Control Point (CCP) are sack fiber, sponge, and metal at the output filtering process. The controlling of the first CCP is done by monitoring the pressure gauge when the filling process is done. The second CCP are tee cable, animal pest, and cloud filter fiber at stearin strainer. This CCP is controlled by stearin strainer cleaning before and after the production process. There are several differences between the HACCP system at PT X and Kraft Foods, such as the quality standard, risk analysis, and documentation format. Based on the analysis that has been done, the percentage of processes belong to Prerequisite Program for RBD CNO are 32,26%; RBD Olein are 35,48%; and RBD Stearin are 33,33%. The percentage of processes belong to Critical Control Point for RBD CNO and Olein are 3,23%; RBD Stearin are 3,33%.

Abstract

XYZ Department at PT X didn’t achieve the yield target, which is one of the Key Performance Indicators, had been determined by Factory in 2012. Some improvements have been developed to increase yield in order to achieve the target. One of the improvements is to verify material transaction between two departments. Another improvement is to reduce the waste, from both Direct Incoming Material (DIM) and non DIM. DIM discussed in this research and contributing the top three waste materials in 2012, were filter rod, cigarette paper, and tipping paper. Non DIM waste that also gave contribution for increasing yield was tobacco. Yield has already increased by doing some of those improvements by 0.45% for AAA product, from 94.85% to 95.3%. Although the target of this year (95.4%) has not been achieved yet, these research’s results show yield increasing trend. In order to keep the consistency of the yield achievement, this Department made bulletin forms as standardization attached on the relevant machines. This bulletin form can be a standard operating procedure for those who operate that machine every day, so that the yield achievement can be stable and increase.

Abstract

PT. X wants to increase profit that obtained from RJK product. Increasing the price can make RJK product will lose with its competing product. PT. X chooses to eliminate wastes that exist in production so higher profit can be obtained. PT. X wants to eliminate non value added activity that exists in RJK production process. Identification waste is done by the help of value stream mapping. Some wastes are located on Main line, CR line, and BYM line. Those wastes happen because of a lot of breakdown on combine line, over bulking, and BYM line does not have independent line because BYM line does not have a cutter. Combine line’s breakdown mainly caused by too long blend changeover or BCO time. Some improvements are done to eliminate waste on Main line, CR line, and BYM line. SMED concept is applied to speed up the BCO time so breakdown time of combine line will reduce. Alarm or visual alert installation is done so overbulking does not happen again. Searching for cutter at other affiliate is done so BYM line has independent line. Those improvements give impact by reducing NVA about 2.44 % at Main line, 0.48 % at CR line, and 1.4 % at BYM line.
