Increased community mobility has an impact on increasing demand for packaged beverage products. Data from Aspadin (the association of bottled water companies) there are more than 1500 brands of bottled water (AMDK) in Indonesia and it is estimated that trade will continue to increase every year. However, the profit margins of bottled drinking water products are not classified as high, so producers must do efficiency. One form of efficiency that can be done is to reduce the waste of packaging production, where most bottled water is made of plastic. This study aims to identify several product defects that often occur during the production process of bottled water based on PET. The process of making plastic-based drinking water packaging is divided into 3 stages. First is to make a bottle preform, the second is the blow molding process, which is the process of making a whole package from a preform, and the third is the process of making a lid. The machines used in these stages are different and in each of the stages successfully classified types of product defects. During the preform manufacturing stage, black specks or contaminants, short shots, bubbles, and flash are found. At the stage of making the whole bottle includes, off center base, failed blowing, arising bracelet, rough parting line. The last defect in the process of making the cap includes excess material flash Short shot, bridge or ring break, leak centergate.

One of the ideal equipment systems is to have high efficiency. The selection of tools that have high efficiency is certainly necessary for the design of a good system by taking into account the factors of reliability, quality, and cost. In this study, a monitoring system with an application and a data logger system was used to monitor the results of sensor readings at the wind power plant (PLTB) and then store the readings in a data logger. By using the black box methodology to test the monitoring system, the result is that the monitoring system works as expected, namely displaying the readings from the sensors at the generator. Using the monitoring system, the measurement process is carried out to find the efficiency value of the PLTB. the comparison of electricity use in public street light facilities when connected to PLTB and when only using batteries and inverters can improve the total remaining voltage on the battery by 89.74%. For the value of the efficiency of the power generated by the generator with the energy used at a 30W lamp load of 2.61%. The data is the result of calculations from the sensor readings that are stored in the data logger.
