Abstract

The use of electrical energy plays a vital role in supporting the continuity of production processes in industrial environments. One critical area that heavily relies on electrical power supply is in the planning of installing a capacitor bank with a detuned reactor. The primary objective of this planning is to enhance the power factor (cos φ) from 60% to 85.2% during full-load operations and up to 94% when operating as per demand simulations. The evaluation of power quality from the implementation of the Capacitor with Detuned Reactor is conducted through simulations using ETAP 12.6.0 software.The simulation results from ETAP 12.6.0 produce comparative graphs between buses equipped with the Capacitor with Detuned Reactor and buses without it, both during full-load operational conditions and when only operating in simulations. The information derived from the simulation provides a deeper insight into the impact of installing the capacitor with detuned reactor on power factor and power quality within this industrial environment. With this understanding, further steps can be taken to optimize the electrical power system within the industrial setting.

Abstract

In an effort to determine the Personal Protective Equipment (PPE) required to protect against arc-flash hazards based on IEEE Std. 1584-2002, a simplified analysis technique was used with the energy limit curve method. The problem addressed was the potential inaccuracies in determining the required PPE level and maximum flash-protection distance when the traditional method does not precisely calculate the incident energy level and flash-protection limit. The purpose of this study was to evaluate a method that could be applied to various types of overcurrent protective devices in electrical systems, thus simplifying the arc-flash analysis. The method involved using the energy limit curve, which allows for quicker determination of the necessary PPE by plotting relay/fuse curves into the energy limit curve. This approach was implemented and tested at PLTU Paiton Unit 7 (PT. POMI). Important findings indicated that the energy limit curve method significantly reduced the time required to determine the appropriate PPE category compared to the IEEE 1584-2002 standard. The results showed that the process of determining the PPE category was more efficient, with fewer data requirements and shorter calculation times. The implications of this research suggest that the energy limit curve method can simplify arc-flash calculations for large industries with numerous buses, enhancing the overall safety protocols by providing a faster and potentially more accurate means of assessing arc-flash hazards and PPE requirements.

Abstract

UKM Citara is developing a seaweed processing business and cultivating catfish in bioflock ponds together with community members as a food security effort due to the impact of the Covid 19 pandemic at the beginning of 2020. Several government/private agencies have visited UKM to learn about seaweed processing and bioflock catfish cultivation, including vocational school students/internship students.  The problem is that the cultivation area of ​​± 2,000 m has not been utilized optimally and SMEs do not yet have an educational tourism concept for their visitors. The aim of the activity is to optimize land use and design a pilot concept for bioflock fish cultivation tourism. The hope is that the cultivated land will be utilized optimally and there will be educational facilities for other parties who come to UKM. The activity method is creating a tourism edu pilot concept in the form of learning tutorials and exploring places at UKM Citara, creating visual images of tourism edu pilots, installing smart ponds, gazebos, gates and irrigation channels in the UKM Citara bioflock fish farming area. The result of this community service activity is the realization of the concept and realization of a tourism edu pilot for seaweed processing and bioflock fish cultivation at UKM Citara which can improve the functionality of ± 2,000 m of empty land which was originally only used for bioflock fish cultivation, then developed into a tourism edu pilot area. which is useful. Visitors can receive education in the form of tutorials on processing seaweed products and cultivating bioflock fish and can explore seaweed processing and bioflock fish cultivation sites. This activity has increased the use of empty land and realized a pioneering educational tourism concept that needs further development.
