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

UNUD GDLN building located in UNUD Sudirman campus acts as an information and communication technology service center as an internet access service provider, radio broadcast and online learning. The UNUD Campus network currently uses a static hybrid routing protocol, where the static routing protocol has the disadvantage that the network administrator must always reconfigure the network if there is a topology change. The Open Shortest Path First (OSPF) dynamic routing protocol can be used as a solution to overcome the weaknesses of static routing protocols because it is more suitable for larger networks and has the advantage of automatically determining the best route. This research aims to analyze the application of OSPF routing protocol in UNUD Denpasar Campus with GNS3 simulation. This research uses Quality of Service (QoS) parameters to analyze network performance, and test scenarios by PING with large data transmission that imitates YouTube video streaming. The results showed that OSPF dynamic routing protocol has better performance and has met the TIPHON standard with very good results for packet loss, throughput, and delay parameters and good results for jitter parameters. Tests on static routing protocol simulations and OSPF routing protocols are carried out by comparing the transmission process based on the resolution on YouTube video streaming imitation, starting with 360p, 480p, 720p and 1080p resolutions. Based on the results of the study, it can be concluded that OSPF routing is more suitable and produces better parameter values when transmitting streaming video with a resolution of 480p, 720p and 1080p, while the transmission of streaming video with a resolution of 360p is more suitable for static routing which is more suitable for transmission with lower resolutions.

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

A data center is a facility used to place electronic systems and related components for the purposes of placing, storing and processing data. The data center is expected to be able to provide services as optimally as possible even in the event of a disturbance. Data center development must consider long-term development plans in terms of services, hardware and infrastructure. The majority of data centers in Indonesia are still standard tier 2. The majority of data centers with tier 3 standards have qualified specifications for companies that require high availability with good planning of the appropriate electrical system.The results of the research that has been done is that in designing a tier 3 standard data center, it must have full backups in the form of generators and UPS to meet the No Shutdown requirements. The use of estimated power designed in this study is 289433 Watts using a main power source from PLN using two transformer units backed up by four generator units and one UPS unit to back up critical loads.

Abstract

The Bali government is trying to re-optimize Bali's tourism potential after the Covid-19 pandemic. To improve the Balinese economy which had declined during the Covid-19 pandemic where foreign tourist visits decreased by 99.93%. In 2022, the tourism industry in Bali finally recovered with an increase in foreign tourist visits by 12.23%. The Bali government needs to optimize the number of foreign tourist visits to re-optimize the tourism sector. One way that can be done is to improve digital-based information services to introduce Bali to tourists. Therefore, to assist the Bali provincial government in optimizing the tourism sector, a recommendation system for tourist attractions in Bali called "MELALI" was created by utilizing the IMDb Weighted Rating algorithm and equipped with a chatbot as a customer service. Based on the results of system testing using Root Mean Square Error (RMSE), the result is 0.0126 (close to zero), this shows that the model made has a small error rate, besides that the chatbot feature has also been able to identify keywords and provide output in accordance with the requested keywords. Overall the system is running well.

Abstract

The monitoring system of the Automatic Transfer Switch - Automatic Mains Failure (ATS-AMF) and battery charger is necessary to facilitate operators in remotely monitoring the system, thus ensuring the continuous supply of water to consumers. An Internet of Things (IoT)-based monitoring system does not require operators to always be on standby at the location, operators can monitor the system remotely outside their working hours. The prototype system is designed using the NodeMCU ESP32 DEVKIT V1 microcontroller and Telegram application for sending and receiving messages remotely, as well as providing spam notifications when disruptions occur in the ATS-AMF and battery charger systems. Data sent from the ATS-AMF includes voltage, frequency, current, power, the power source being used, and disruption data from both the PLN electricity source and the generator. Data sent from the battery charger includes voltage, current, battery charging stages, battery state of charge, and disruption data. Test results show a 100% success rate in data transmission through the Telegram chatbot, with an average delay ranging from 4.8 seconds to 5.7 seconds. This monitoring system ensures effective remote monitoring to maintain the smooth flow of electricity and the continuous supply of water to consumers.
