Abstract

Shrimp is one of the prima donnas of Indonesia's mainstay exports from the fishery sector which needs to be improved both in terms of quality and quantity. The use of aerators as an effort to improve the quality and quantity of harvest used by pond farmers today generally still uses a manual system, where the operation of the aerator is still based on experience, not from the quality of dissolved oxygen in the pond needed by fish or shrimp in the pond. In this study, the application of an aerator to improve the quality of dissolved oxygen both in quality and quantity, is equipped with an IoT (Internet of things)  method that can instruct the aerator to operate as desired using a smartphone.  The components used in this tool consist of solar cell panels  as renewable  power plants, Aerator Pumps, and ESP8266 WiFi. In this data collection activity, in fluctuating weather conditions. Especially during rainy conditions, data retrieval is paused because test conditions do not allow it to produce a current data reading of 0 amperes. From the logger data recording,  it can be seen that the highest current value that can be absorbed through solar panels is 2.40 Amperes obtained on day 3 of testing

Abstract

Electricity needs at PT. PUSRI is currently generated by four main generating units in the form of a Gas Turbine Generator (GTG). The three power plants are PUSRI-II (2006-J), PUSRI-III (3006-J), PUSRI-IV (4006-J) each with a capacity of 21.588kVA. PUSRI-IB (5006-J) with a capacity of 26.65kVA. Each unit is operated in parallel via a 13.8 kV syncronizing bus. However, for reasons of generator efficiency at PT. PUSRI with gas costs that are quite expensive will gradually be replaced by a Steam Turbine Generator – Coal (STG-BB) generator. The contribution of this paper uses the Particle Swarm Optimization (PSO) algorithm to find the optimum output (MW) from each generating unit. The results of the PSO calculation provide a better solution performance compared to the real system with the same generated power variation, namely 34.25 (MW) to 37.63 (MW). The cost savings obtained from the comparison between the PSO method and the real output of the system is Rp. 5,180.509 at load 34.25 (MW) and Rp. 6,416.864 at 37.63(MW) load.

Abstract

The usefulness of monitoring systems in the electric power system supports the importance of people's work today. One of which is the monitoring system at the generator. The monitoring system for Wind Power Plant (WPP), Solar Power Plant (SPP), and electricity from State Electricity Company (PLN) use IoT (Internet of Things) in the form of Sonoff Pow R2. With the monitoring system on this tool, the parameter values for WPP, SPP, and PLN can be seen and monitored online via a smartphone. The purpose of this research is to design a monitoring system for WPP, SPP, and PLN based on the Internet of Things (IoT) to determine the value of the output power. In addition, this system can distinguish load parameter values when WPP, SPP, and PLN are supplied directly (real time) and monitored online using the Sonoff Pow R2 app and the Ewelink App. This study uses the methodology that started the process of designing and manufacturing systems and designing the wiring that has been formed from the process of making tools and testing results. The results obtained from the experiment show that the current values in WPP, SPP, and PLN that appear on the monitoring screen are stable.  The stable condition values are measured and tested when power is used when loading through sonoff.  For the power value, the power value in PLN is stable, whereas in WPP and SPP has increased. For the voltage, the voltage value from PLN does not reach 220 V, whereas the voltage value from WPP and SPP reaches a value of 220 V.

Abstract

This research presents a vessel tracking system that provides real-time coordinate and speed information. The idea behind the development of this system originated from Automatic Identification System (AIS) technology, which functions as a vessel monitoring system in maritime areas. The system aims to improve navigation safety, monitor vessel traffic, and maritime security. In Indonesia, AIS is regulated by the Ministry of Transportation. However, this technology has not yet been implemented in river waters. In addition, AIS is a complex and expensive system. In this research, geographic location detection information in the form of a vessel tracking system is obtained using the UBlox Neo-6M GPS module based on LoRa technology. The LoRa mechanism periodically sends location data and vessel speed from the node to the gateway. The data is then sent to the ThingSpeak server using the MQTT protocol. On the server, the data can be accessed for further analysis. The developed system shows that the research can be realized and the system functions properly through a series of experimental tests. While in the in situ test, the system displayed good performance on LoRa SF 7 configuration with a signal strength of -118 dBm within the communication range of 1000 meters. This result can be improved by considering the MAPL value of -138 dBm.

Abstract

Intisari Setiap yang berputar memiliki potensi energi kinetik, tidak terkecuali putaran kubah masjid. Penelitian ini bertujuan untuk mengetahui potensi pemanfaatan kubah putar masjid sebagai penghasil energi listrik skala kecil. Generator yang diuji cobakan adalah generator magnet permanen dan generator DC yang dirangkaikan dengan turbin kubah putar. Pengujian dilakukan di dua lokasi, di Jembatan Musi 2 Palembang dan di perairan Sungsang Kabupaten Banyuasin untuk mengukur besaran tegangan dan arus output yang dihasilkan pada berbagai kecepatan angin menggunakan multimeter dan anemometer. Hasil penelitian menunjukkan bahwa tegangan yang dihasilkan oleh putaran kubah masjid menggunakan generator magnet permanen mampu mencapai 14,21 V pada kecepatan angin 3,8 m/det dibandingkan dengan generator DC yang hanya mencapai 3 V pada kecepatan angin 8 m/det. Jika ditinjau dari besaran arus, generator magnet permanen menghasilkan arus konstan sebesar 0,3 A sedangkan pada generator DC arus yang dihasilkan tidak terukur karena nilainya yang amat kecil. Penelitian ini menunjukkan bahwa kubah putar masjid dapat dijadikan sebagai turbin angin pada daerah yang memiliki kecepatan angin rendah. Kata kunci kubah masjid putar,generator magnet permanen,generatorDC, turbin angin kecepatan rendah Abstract - Every spinning has kinetic energy potential; the mosque dome is no exception. This study aims to determine the potential use of the mosque's turning dome as a producer of small-scale electrical energy. Two types of the generator were tested, which were permanent magnet generator and DC generator, which were coupled with a rotary dome turbine. The test was carried out at two locations, at Palembang Musi 2 Bridge and in the waters of Sungsang, Banyuasin Regency, to measure the amount of voltage and output current generated at various wind speeds using a multimeter and anemometer. The results showed that the voltage generated by the mosque's dome rotation using a permanent magnet generator was able to reach 14.21 V at wind speeds of 3.8 m / sec compared to DC generators, which only reached 3 V at 8 m / s wind speed. When viewed from the amount of current, permanent magnet generators produce a constant current of 0.3 A while in DC generators, the current generated is not measurable because the value is minimal. This research shows that the mosque's rotary dome can be used as a wind turbine in areas that have low wind speeds. Keywords rotary mosque domes, permanent magnet generators, generator DC, low speed wind turbines

Abstract

In general, the Brushless DC motor speed controller uses an Atmega 16 microcontroller and a MOSFET, which often increases the MOSFET's temperature, especially when the motor is loaded. This article discusses the use of the IC NE555 and CD4017 as a frequency regulator to the MOSFET gate by periodically igniting the forward voltage from the change in the potentiometer value. We carried out the test in an unloaded and unloaded state with voltage variations of 2.5 Vac, 7.5 Vac, 12.5 Vac, and 19.5 Vac. The test results show an excellent tool response where the higher the frequency value, the motor speed will increase. The maximum speed when unloaded reaches rpm at a frequency of 574.6. Whereas in the load test, the full speed reaches 20987 rpm at a frequency of 524.675 Hz. During the test, there was no temperature increase in the MOSFET.
