Abstract

Blow molding is a bottle molding process aimed at forming PET preforms into PET bottles. This process is highly influenced by heat, which functions to soften the PET preform to facilitate its formation in the subsequent stages. Therefore, temperature control is a critical factor in this process. The energy balance method was used to calculate the heat required during the preform heating process in the heater unit. The results showed that the heat required during the preform heating process in the heater unit was 6,441,218.72 cal/hour, 6,531,114.65 cal/hour, and 6,486,129.51 cal/hour. The heat transfer efficiency of the heater for the preform was 90.74%, 92.00%, and 91.37%, respectively.

Abstract

The application of Occupational Safety and health (K3) is very important in the work environment because it is closely related to the risk of accidents, safety and health when carrying out work. Various efforts have been made by the Tenera machinery factory (PMT) PTPN IV to minimize work accidents and diseases caused by work by installing warning signs, the use of complete personal protective equipment (PPE), providing good nutrition and regular health checks. However, the lack of awareness of K3 is still found in PMT PTPN IV Dolok Ilir workers. This can be seen from the still finding of minor work accidents and occupational health effects shown from the results of employee health reports. The methods used in this service activity are socialization, training, discussion on the basics of K3 welding for employees of PMT PTPN IV, so that factory employees are able to identify potential hazards that can occur in the workplace and accident prevention measures. The results of the socialization and training of welding K3 activities that have been carried out are expected to increase employee awareness of the importance of K3. So that the company is able to maintain the zero accident predicate.
