Abstract

The data acquisition for monitoring the water flows in real-time, which is available at any time, is needed for water management purposes. This paper aims to build a prototype of a water flow measurement system in an open channel of a rectangular weir box design using the American Standard Testing and Material (ASTM). This research contribution is a development of a water flow measurement, which can be used as a simulator for studies on measuring water discharge in real cases in the field. More, this instrument is based on the data logger using Arduino, which is designed at a low cost and is easy to use. This water flow equipment can be measured in real-time, so that data information can be directly obtained for analysis. The design of a data acquisition system can display water discharge data in real-time from time to time and allows data storage (data logger) as historical data that can be displayed whenever needed. The Arduino UNO ATMEGA 328 microcontroller was programmed to read the HC-SR04 water level sensor on a distance-based weir box displayed on the LCD. Monitoring and recording of data were displayed on the Parallax Data Acquisition tool (PLX-DAQ) software add-on for Microsoft Excel in real-time. The prototype was able to provide a real simulation of the water flow calculation process until the maximum design capacity of 784,384.87 liters per day. Tests on the overall performance of the water flow measurement system were carried out using flowing water media at 3 different flow conditions based on time. From the average log data of the tests carried out, the deviation of the measurement data against the ASTM calculation theory on average of 0.8 liters/minute. These results were quite good because of the 16,502 liters of water measured. The difference in the calculation results was only 1.003 liters.

Abstract

Passive LC filters are commonly installed at the output of Variable Speed Drives (VSDs) to limit harmonic distortion in Electrical Submersible Pump (ESP) systems. However, capacitor degradation may reduce filter effectiveness and alter the electrical behavior of the entire drive system. This paper examines the impact of passive filter capacitor failure in a 390 kVA VSD-driven ESP installation using field measurements obtained under three operating conditions: before the filter, during normal LC filter operation, and after disconnection of a failed 200 ?F capacitor while the output reactor remained in service. Harmonic performance was evaluated in accordance with IEEE Std 519-2022, followed by impedance and resonance analyses to explain the measured responses. The results indicate that capacitor removal increased THDi from 4.30% to 12.30% and THDv from 39.50% to 61.23%, confirming a substantial reduction in harmonic suppression capability. The analytical evaluation further shows that changes in filter impedance promote resonance between the output reactor and the downhole cable capacitance. A preliminary single-tuned passive filter design is finally proposed to improve harmonic mitigation under comparable operating conditions.

Abstract

Ikan air tawar memiliki kandungan protein yang tinggi yang disukai oleh masyarakat banyak, selain harganya yang relative terjangkau dan banyak dibudidayakan. Ikan air tawar merupakan makanan yang cepat megalami pembusukan. Di Riau sendiri yang terkenal dengan ikan salai yang diproses dengan pengasapan supaya ikan lebih tahan lama dan menambah cita rasa pada ikan, pengasapan ikan secara tradisional dengan sistem terbuka dinilai kurang efektif karena panas dan asap yang dihasilkan akan banyak terbuang. Dalam penelitian ini dikembangkan sistem pengasapan otomatis dengan menggunakan elektrik dan tertutup, sehingga proses pengasapan lebih efektif. Alat pengasapan ikan otomatis berbasis mikrokontroler Arduino AT Mega 2560 dan sensor DHT 22 untuk mengontrol suhu dan kelembaban secara otomatis. Hasil penelitian diperoleh pengasapan secara konvensional membutuhkan waktu 12-13 jam, sedangkan pengasapan ikan otomatis membutuhkan waktu 7-8 jam. Nilai suhu yang digunakan pada alat pengasapan ikan yaitu mencapai 80˚C ketika nilai suhu melebihi 80˚C maka secara otomatis element (pemanas) akan mati. Kipas sebagai alat untuk mensirkulasi asap akan bekerja pada suhu 60 oC berhenti bekerja pada suhu 58 oC.
