Abstract

Rugi-rugi jaringan pada sistem distribusi dengan jenis radial dapat diperbaiki dengan cara pemasangan kapasitor.  Kapasitor memiliki nilai kapasitansi yang beragam dengan biaya yang tidak linier dengan besarnya kapasitas dan umur pemakaian untuk tegangan menengah berkisar 20 tahun.  Dengan demikian untuk memasang kapasitor dalam sistem distribusi yang besar merupakan permasalahan multi objektif yang dapat dilakukan dengan algoritma.  Pada penelitian ini menggunakan algoritma APSO untuk meminimalkan rugi-rugi jaringan dengan mempertimbangkan biaya investasi   selama 20 tahun dengan tetap membatasi tegangan minimal 0.95 pu dan besarnya kapasitor tidak melebihi kebutuhan  daya reaktif beban. Metode ini diujikan pada sistem distribusi 33 bus IEEE dengan tegangan 12.66 kV dengan perbandingan analisa aliran daya menggunakan software ETAP.   Hasil simulasi menunjukan bahwa pada kondisi awal memiliki rugi-rugi jaringan sebesar 202.6934 kW dengan tegangan minimum sebesar 0.913 pu setelah dilakukan pemasangan kapasitor didapat   perubahan tegangan minimum menjadi 0.9502 dengan rugi-rugi jaringan    sebesar 137.6579 kW dengan biaya investasi $218689.28 dalam kurun waktu 20 tahun. Kata kunci:  APSO, biaya investasi, kapasitor, rugi jaringan.

Abstract

Di dalam suatu pembebanan transformator diharapkan nilai pembebanannya tidak melebihi standard yang ditetapkan, yaitu 80%. Pada pembebanan transformator diharapkan nila pembebanannya di masing-masing fasa (S,R,dan T) seimbang. Bila terjadi ketidak seimbangan beban maka nilainya tidak boleh melebihi 2%. Akibat adanya ketidak seimbangan beban maka timbullah arus di penghantar netral. Arus yang terdapat pada  netral membuat terjadinya losses. Setelah melakukan analisis transformator di PT Henson Farma pada saat beban puncak persentase pembebanannya sebesar 60,2% (dibawah standard spln) dan nilai ketidak seimbangan beban yang pada beban puncak sebesar 0,33 %(dibawah standart spln). Namun di beberapa mdp nilai ketidakseimbangannya melebihi standard. Nilai Losses dipenghantar netral sebesar 1,4265 Kw dan terdapat derating trafo sebesar 2 kva atau 1,8 Kw.

Abstract

DC motors are a popular topic because they are widely applied in various electronic equipment. So, this requires a control that is fast and reliable. The development of optimized control methods is growing rapidly with the discovery of several new methods. Marine predator algorithm (MPA) is an optimization method based on marine life between living things. This article discusses the application of the MPA method for optimizing fractional order PID (FOPID) control on DC motors. The implementation of the FOPID controller is also difficult because the fractional calculus operators of the FOPID controller cannot be directly implemented in numerical calculations. The method proposed in this article is the FOPID-MPA method. To get a performance test of the proposed method, this study uses several comparison methods, namely the seagull optimization algorithm (ASO), chimp optimization algorithm (ChOA), and sine tree seed algorithm (STSA). This study also uses a variation of the reference speed to get the performance of the proposed method. From the experiment it is known that the FOPID-MPA method gives the best performance. The FOPID-MPA method has an overshoot value of 4.34% compared to the PID-MPA method in case study 1 and has an integrated of time-weighted-squared-error (ITSE) value of 7.44% better than the PID-MPA method in case study 2.

Abstract

This paper presents the reptile search algorithm (RSA) method to optimize the proportional integral derivative (PID) parameters on direct current (DC) motors. RSA was adopted from crocodile hunting behavior. Crocodile behavior is modeled in two important steps: surrounding and attacking prey. The RSA method was applied using twenty-three classical test functions. The search method of the proposed RSA method with other existing algorithms such as particle swarm optimization (PSO), and differential evolution (DE). Integral multiplied by absolute error (ITAE) and integral of time multiplied squared error (ITSE) were used as comparisons in measuring the performance of the RSA method. The results show that the proposed method, namely RSA, has better efficiency. Optimization of PID parameters with RSA on DC motor control shows superior performance. From the experiment, the ITSE average value of the RSA method is 4.17% better than the conventional PID method.

Abstract

One fundamental energy needed for many aspects of daily living is electricity. Most commonly known application of electricity is in the Megaluh Village lobster pond. Due to the fact that air is essential to lobster life, an aerator must be used. Due to the distance between the farmer's residence and other issues, the aerator needs to be operated every 24 hours. The goal of this project is to build an automatic feeder based on ESP32 and a solar plant as a substitute energy source. The experiment's findings indicate that on day two, the solar panel reached its maximum efficiency of 55,74W. On the fifth day, though, the average daily was only around 41,07 W. In relation to the battery life indicator, it is around 12,72V and 2,96A. Furthermore, the battery's output voltage on the last day was 12.03 V and its resistance was 2,64A. Additionally, the average for the inverter's output over five days is 230,5V and 0.13A. The results of the optimal angle servo were 47° because provided according to the required weight, which was 10 grammes. When using a digital timing device, a load cell can achieve a 99% accuracy rate.
