Abstract

Potential of renewable energy is essential to support Bali Clean Energy, one of the energy that can be exploited is Solar energy. However, by 2023 the potential has been exploited only 1,48 percent. One of the reasons why Solar Plant construction in Bali is slow is because it is difficult to find land large enough to build Solar Plant on a large scale. However, solution to overcome land constraint is to utilize the water body through floating Solar Plant application. In the Project, the Floating Solar Plant Sidan Dam utilized body of the Water Dam and work pictures from the Planing of the Sidan Dam, with such data being used to determine the Floating solar Plant System in Sidan Dam. The design results showed that floating Solar Plant in Sidan Dam has a potential capacity of 1.45 MWp with a total of 2640 units solar panel and uses 12 units of inverters of 1.100 kW capacity. The energy production produced by the floating Solar Plant in a year was 2.564.007 kWh.

Abstract

Every daily activity requires electrical energy. Electrical energy loads vary. Harmonic distortion is one of the results of current and voltage wave disturbances caused by non-linear loads, such as lamps, computers, and air conditioners, among others. This causes a decrease in the quality of electric power. High resonance disturbances can cause increased harmonics which can reach 4 to 10 times under full charge conditions. One way to overcome harmonic disturbances is by using a harmonic filter. In this study, an active shunt filter with PI control is used to reduce harmonic resonance disturbances. The THD value according to the IEEE 519-2014 standard is obtained by using this harmonic filter. In this study using Matlab Simulink simulation software. The THD obtained before the simulation was carried out, namely THDv in the R phase = 1.62%, S = 1.64%, T = 1.71%, THDi in the R phase = 14.73%, S = 12.96%, T = 13.53%. The THD obtained after the simulation is THDI at each phase R = 3.29%, S = 3.01%, T = 4.53%.

Abstract

The issue of waste, particularly plastic waste, remains a challenging problem without a definitive solution. Plastic waste, especially that made from High-Density Polyethylene (HDPE), takes an extensive amount of time to decompose. Currently, plastic recycling machines are priced in the hundreds of millions, making them less accessible. Therefore, there is a need for affordable machines that function effectively alongside existing ones. This research introduces a hot press machine for recycling HDPE plastic. The hot press machine is capable of recycling HDPE plastic waste and offers the advantages of being portable, compact in size, and cost-effective. Following the design phase, the machine is capable of producing plastic boards with a thickness of 1 cm, utilizing 3.7 kg of plastic, and requiring a molding time of 2 hours and 15 minutes at a pressure of 4.36 MPa.Subsequent testing involved analyzing three factors to determine the significant influence of factor A (heating temperature) and factor B (heating time) on energy consumption. The goal was to identify the interaction that yielded the smallest average energy consumption.

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.
