Rationalization of purchases by making contract also succeeded in reducing the average lead time of making purchase orders up to 34%. Purchase by contract also resulted in cost efficiency in the form of saving to P/L of 4% and saving to budget of 10%. Cost efficiency calculations for the purchase of printed goods are done as supporting evidence. The rationalization of purchases on printed goods will result in a cost efficiency of 19%. Rationalization of purchase can cause problems of delays in the supply of goods. The suggestion given is the calculation of safety stock and reorder point for the purchase of printed goods.

Abstract

PT. X is one of animal feed company. PT. X plans to get ISO 22000: 2005 certification. One of  the requirements in order to get ISO 22000: 2005 is PT. X must implement Hazard Analysis Critical Control Point (HACCP). Quail feed causes hazards in the stage of production process as flea, fungus, Salmonella sp., Arsenic, Lead, Mercury, Cadmium, aflatoxin, metal, paper, plastic, rope, wooden, over/under scale mixer hence need to design HACCP system. The design of HACCP system is capable of controlling the potential hazards. In addition HACCP as a guarantee of livestock feed quality to meet the demands of consumers. The design of HACCP at PT. X for quail feed products consists of the stages such as making product descriptions, creating process flow diagrams, the seven principles of HACCP, and verification of HACCP design. The hazards that already been analyzed do not include CCP but only Operational Pre Requisite Program (OPRP). Documentation of HACCP consist of Operational Pre Requisite Program (OPRP) Plan documentation. The hazard in the documentation of OPRP Plan is hazard of aflatoxin in the stage of the packing process.

Abstract

PT AW PLUS UPVC Bali is a company engaged in the production of UPVC-based doors and windows located on the island of Bali. The production process of PT AW PLUS UPVC Bali involves tools, cutting machines, and welding machines, thus if the production process is not carried out carefully, injuries can occur. This company also does not have a work hazard identification document, thus the company is still unable to fully understand the risks of accidents that can arise in each of its production processes. Therefore, the purpose of this final project is to design hazard identification, risk assessment, and risk control or HIRARC to reduce the risk of injury in the production process of PT AW PLUS UPVC Bali. The writing of this final project starts with direct observation and interviews with the company. After the risk has been identified, a risk assessment will then be carried out by determining the level of likelihood and severity of the risk. The results of the assessment show 43 potential hazards with medium risk rating, and 3 potential hazards with extreme risk rating.

Abstract

PT X is a manufacturing company that produce healthcare product such as medicated and non-medicated plaster. The company do not have occupational health and safety division yet, so there was several dangerous accident that have occurred. Risk analysis is carried out to detect potential risk before accident happened. Risk analysis hopefully could make a sense of security and comfort for the employees that work there. The research begins with a literature study on HIRARC, company observations, hazard identification, risk assessment, then risk control. Risk control will be validated first by the company. If it is valid then an assessment will be carried out to see the estimated reduction of risk value after the risk control is implemented. The result of risk analysis is that, there are several potential hazards in the poduction area. The potential divided into 10 mild potential, 13 moderate potential, 6 significant potential, and 2 high risk potential. Risk controls are designed using risk control hierarchy that is elimination, substitute, technical design, administrative engineering, and personal protective equipment (PPE). After risk control is done, the risk reduction forecast is moderate potential become 1, significant potential become 3, and high risk potential is none.
