Analisis Pengaruh Pembebanan Terhadap Efisiensi Transformator Daya 30 MVA PLTMG Ambon Peaker 30 MW

2025-01-15T15:08:59+07:00

Transformator daya merupakan suatu peralatan listrik yang berperan penting dalam penyaluran energi listrik dari pembangkit sampai ke konsumen yang efisiensinya harus tetap dijaga agar dapat beroperasi dengan baik. Efisiensi transformator merupakan perbandingan antara daya keluaran (P_out) dengan daya masukan (P_in) dan dinyatakan dalam persentase, dimana dalam pengoperasiannya efisiensi juga dipengaruhi oleh rugi-rugi daya yang timbul yakni rugi-rugi inti dan rugi-rugi tembaga. Semakin besar pembebanan, maka kerugian daya yang dihasilkan semakin meningkat. Oleh karena beban yang ditanggung PLTMG Ambon Peaker 30 MW bersifat fluktuatif dan untuk mengetahui pengaruhnya terhadap efisiensi, maka transformator blok #1 menjadi fokus utama untuk diteliti. Dalam penelitian ini dilakukan analisis perhitungan menggunakan metode kuantitatif dengan menghitung besar rugi-rugi daya dan efisiensi transformator. Jenis data yang diperlukan untuk melakukan analisis perhitungan ini yaitu: Spesifikasi Teknis Trafo dan data historistis pembebanan tertinggi, arus, serta tegangan trafo tahun 2023. Hasil penelitian menunjukkan bahwa pengoperasian transformator blok #1 pada GI Waai di PLTMG Ambon Peaker 30 MW pada pembebanan tertinggi 16,61 MW menghasilkan efisiensi sebesar 99,6285%. Dimana pada kondisi pembebanan ini efisiensi cenderung kecil diakibatkan rugi tembaga meningkat secara signifikan dengan meningkatnya arus beban (karena rugi-rugi sebanding dengan kuadrat arus). Sedangkan efisiensi tertinggi transformator 99,6506% terjadi di bulan Mei dengan besar pembebanan 13,05 MW. Hal ini dapat terjadi pada kondisi pembebanan tertentu, dimana rugi-rugi yang dihasilkan transformator saat beroperasi minimum atau nilainya kecil. Hal ini menjelaskan adanya pengaruh signifikan pembebanan yang fluktuatif terhadap efisiensi transformator, yakni semakin besar pembebanan maka efisiensi akan semakin kecil.

Good street lighting planning is essential, especially in areas prone to accidents and crime. Good street lighting can reduce the risk of accidents and increase the sense of security in public areas, providing security, convenience, and comfort for road users, especially at night or in bad weather conditions. However, street lighting is often a significant source of energy consumption. Therefore, optimising the street lighting system to improve energy efficiency is necessary. The study results showed that the existing lighting system using 250 W high-pressure sodium (HPS) lamps has weaknesses in terms of energy efficiency and light distribution quality. Simulations using Dialux showed that the average luminance of existing lighting only reached 0.6 cd/m² with a uniformity level of 0.4, and energy consumption reached 20,000 W along the road. Lighting optimization using 120 W LED lamps provides significant improvements in energy efficiency and lighting quality. The average luminance increased to 0.8 cd/m² with a uniformity of 0.6, while energy consumption decreased by 52%, from 20,000 W to 9,600 W. In addition, the glare level decreased from 30 to 25, indicating an increase in visual comfort. These results indicate that the implementation of LED lights can not only improve the quality of street lighting but also have a positive impact on energy efficiency and reduced operating costs.

The design of the wireless water level sensor system aims to monitor water in the river effectively and efficiently. The system utilizes wireless technology to transmit data in real-time, allowing users to monitor water levels remotely. In this project, the water level sensor was selected for its high accuracy in measuring the depth of the water. The data collected by the sensors will be transmitted via a wireless communication module such as LoRa that we use to a web-based application or mobile device, where the user can visually monitor the status of the water level.

The system test method is carried out by monitoring the results of water level identification in the river to ensure accuracy. The results show that the system not only provides accurate data, but also reduces the need for manual intervention, thereby improving operational efficiency. In addition, the implementation of this system also provides convenience in disseminating information warning of the existence of.

Monitoring water consumption with the Internet of Things (IoT) is a significant innovation in improving water utilization efficiency in multi-story buildings. This research develops a monitoring system on a three-story building prototype, which combines the MQTT protocol, the Node-Red visualization platform, and two sensors: the YF-B6 and the analog water flow meter sensor. The YF-B6 sensor measures the number of pulses from the water flow to determine the volume, flow rate, and velocity of the water, while the analog water flow meter sensor is integrated with the ESP32-CAM module to capture images of the water flow indicator and process them into volume values using image processing. Data from both sensors are sent to the cloud MQTT broker and visualized interactively through the Node-Red dashboard. This system is implemented on a three-story building prototype to replicate the distribution and monitoring of water usage on each floor. The research results indicate that this system can provide water consumption data with an error percentage of 0.2% and an absolute error of 0.03 m³. This system will also be used for the industrial automation workshop learning module to introduce the Internet of Things (IoT) in an educational environment.

The agricultural sector plays a vital role in national food security; however, land scarcity due to rapid urbanization has encouraged the adoption of alternative methods such as hydroponics. This method enables plant cultivation in controlled environments, yet manual monitoring of key parameters—such as water temperature, pH, and water level—is often inefficient and error-prone. This study presents the development of an automated monitoring and control system based on the Internet of Things (IoT), utilizing a publish/subscribe architecture. The system is built using NodeMCU V3 and Arduino Uno, equipped with temperature, pH, and ultrasonic sensors, and implemented in a Deep Water Culture (DWC) setup. Testing results indicate that the system can accurately read environmental parameters and transmit data in real-time to Firebase, achieving a throughput of 7753 Bps, 0% packet loss, and an average delay of 0.197 seconds from NodeMCU to Firebase, and 2.226 seconds in the reverse direction. The heater, chiller, and water pump operate automatically based on predefined thresholds (±3°C for temperature and +2 cm for water level). All parameters can be remotely monitored and controlled via an Android application. The system has proven to be effective and efficient in supporting precision agriculture and offers a sustainable solution for optimizing hydroponic cultivation in limited land areas.
