Abstract

The continuity of electricity supply from generators to consumers cannot always be guaranteed due to various factors such as planned outages, distribution failures, and the impacts of natural disasters. The Regional Public Water Company (Perumda) Tirta Sanjiwani has adopted generators as Backup Power Sources to ensure the availability of water supply to consumers. However, the Blangsinga Production Unit of Perumda Tirta Sanjiwani faces challenges in switching electricity supply between PLN and the generator set (genset), especially in operations requiring uninterrupted continuity. To overcome the instability of the electricity supply from PLN, the use of automatic systems such as ATS (Automatic Transfer Switch) and AMF (Automatic Main Failure) is necessary. The function of ATS is to switch from PLN to the backup power source (genset) when there is a disturbance or outage in PLN. AMF is responsible for detecting failures in PLN and initiating the genset as well as transferring the load to the backup power source when there is a failure in the main power supply. The ATS-AMF system prototype is designed using voltage sensors, frequency sensors, current sensors, and relays to ensure optimal performance and responsiveness to environmental conditions and power supply conditions.

Abstract

The current issue of plastic waste has not yet received appropriate handling, resulting in the inadequate control of plastic waste management practices. Particularly, High Density Polyethylene (HDPE) is still widely encountered. HDPE is a thermoplastic made from petroleum with a melting temperature of 160ºC-240ºC, characterized by being slightly cloudy, transparent, and elastic. This research will conduct testing using a complete randomized design (RAL) factorial analysis with 3 factors to determine the influence of factor A (heating temperature), the influence of factor B (heating time), and the influence of factor C (opening temperature) on flashing defects and warpage defects in HDPE plastic. Based on the testing of flashing defects, the significant influencing factors are factor A (heating temperature), factor B (heating time), factor C (opening temperature), and the interaction of factors AB (heating temperature and heating time). Meanwhile, the significant influencing factors on warpage defects are factor A (heating temperature), factor B (heating time), and the interaction of AB (heating temperature and heating time). Based on this research, the characteristics of HDPE plastic can be determined.

Abstract

Buck-boost inverter is one tool that can convert Direct Current (DC) voltage into Alternating Current (AC) voltage while simultaneously increasing and decreasing the output voltage. On the other hand, there is a problem with induction motors, namely the presence of Common Mode Voltage (CMV) or the voltage between the neutral point of the motor and ground which can accelerate wear on the bearings and damage to the motor. One method that can reduce CMV is by using an active filter. Another problem due to the use of inverters is that there are harmonics due to the switching process. This research will examine the effect of adding modified BBI plus an active filter to a three-phase induction motor on CMV and THDv. This research process begins with designing a circuit simulation in the MATLAB application, then simulation testing is carried out to see its effect on CMV and THDv values. BBI simulation test results after the addition of active filters with conventional inverter circuit CMV worth 250V with THD worth 6744.45%, while the BBI circuit coupled with active filters worth 22V and THDv worth 114.53%. As well as the BBI circuit plus an active filter, CMV is worth 2.6V with THDv worth 65.30%.
