Abstract

Motor DC didesain untuk dioperasikan bersumber arus searah (DC). Motor DC lazim digunakan pada perangkat-perangkat elektronik dan listrik, serta aplikasi di industri, seperti: penggerak robot, motor konveyor, penggerak pintu geser otomatis, dan yang lainnya. Artikel ini menguraikan tentang pemodelan dan simulasi sistem kendali motor DC menggunakan pengendali PID dan pengendali berbasis Logika Fuzzy untuk mendapatkan optimisasi berdasarkan fungsi sistem kendali, yaitu : pengukuran, pencatatan, perhitungan, perbandingan dan perbaikan. Penelitian ini menggunakan motor DC tipe Pittman dengan melakukan pemodelan matematika motor DC, model kontroler PID, dan model kontroler Fuzzy dalam bentuk simulasi LabView, selanjutnya dianalisa dan dibandingkan mengenai performansi, karakteristik, dan respon transien yang dihasilkan oleh kendali PID dan kendali Fuzzy yang diterapkan dalam motor DC. Hasil dari simulasi memperlihatkan respon keluaran dengan pengendali Fuzzy mencapai keadaan tunak lebih cepat sebesar 2,73 ms dibandingkan dengan menggunakan pengendali PID. Namun demikian, respon sistem dengan pengendali Fuzzy memperlihatkan adanya overshoot sebesar 3,52 %. DC motors are designed to be operated from direct current (DC). DC motors are commonly used in electronic and electrical devices, as well as industrial applications, such as: robot drives, conveyor motors, automatic sliding door drives, and others. This article describes the modeling and simulation of a DC motor control system using PID controllers and Fuzzy Logic based controllers to obtain optimization based on control system functions, namely: measurement, recording, calculation, comparison and improvement.

Abstract

Refrigerant atau freon merupakan zat pemindah panas pada sebuah sistem pendingin, tanpanya sistem refrigerasi tidak akan bekerja. Namun refrigerant juga dapat menyebabkan masalah konsumsi listrik yang tinggi dan juga dapat menyebabkan kerusakan pada kompresor tergantung dari tekanan refrigerant dan juga kondisi AC (Air Conditioner) itu sendiri. Dalam kasus tersebut terjadi ketidak pastian kondisi refrigerant, khususnya pada saat pengisian refrigerant. Hal ini bisa disebabkan oleh tekanan, arus, dan kondisi AC (Air Conditioner) itu sendiri. Oleh karena itu, pada penelitian ini dibuat sebuah alat pengisian refrigerant otomatis yang dapat mengetahui kebutuhan refrigerant dengan menggunakan Logika Fuzzy metode inferensi Mamdani, sensor tekanan Transmitter G, dan sensor arus SCT013, sehingga diharapkan dapat mencegah konsumsi listrik yang tinggi, membantu mempermudah pekerjaan teknisi AC (Air Conditioner) dalam pengisian refrigerant sehingga kebutuhan tata udara dapat terpenuhi. Logika Fuzzy dengan metode inferensi Mamdani yang diterapkan pada alat mampu menyelesaikan masalah ketidakpastian dalam pengisian refrigerant, dengan cara memetakan variabel tekanan dan variabel arus dalam fungsi keanggotaan masukan yang mana masing-masing variabel tersebut memiliki tiga himpunan. Sedangkan, variabel pengisian refrigerant dipetakan dalam fungsi keanggotaan keluaran dengan dua himpunan. Pada akhirnya diperoleh sebuah keputusan berupa nilai status pengisian yang mampu bekerja secara otomatis dengan memanfaatkan hasil proses defuzzification sebagai kontrol solenoid valve dengan hasil pengujian sistem AC (Air Conditioner) 1/2 PK R32 merek DAIKIN adalah 170 Psi (pound per square inch) untuk tekanan dan 1,64 A untuk arus. Hasil pengukuran sensor tekanan dan arus memiliki rata rata error dari 10 kali pengukuran, yaitu 0,3% untuk sensor tekanan transmitter G1 dan 3,21 % untuk sensor arus. Refrigerant, known as freon, is a heat transfer substance in the cooling system, which is necessary for the refrigeration system to work. However, refrigerants can also cause problems with high electricity consumption. It can also cause damage to the compressor depending on the pressure of the refrigerant and the condition of the Air Conditioner. In this case, there is uncertainty about the condition of the refrigerant, especially when charging the refrigerant. This can be caused by pressure, current, and the Air Conditioner's condition. Therefore, in this study, an automatic refrigerant filling device was created that can determine refrigerant needs using the Fuzzy Logic Mamdani inference method, Transmitter G pressure sensor, and SCT013 current sensor so that it is expected to prevent high electricity consumption, help make the work of Air Conditioner technicians easier in charging the refrigerant so that the need for air conditioning can be fulfilled. Fuzzy logic with the Mamdani inference method applied to the tool can solve the problem of uncertainty in refrigerant filling by mapping the pressure variables and current variables in an input membership function where each variable has three sets. Meanwhile, the refrigerant charging variable is mapped into an output membership function with two sets. In the end, a decision was obtained in the form of a filling status value that was able to work automatically by utilizing the results of the defuzzification process as a control solenoid valve with the results of testing the Air Conditioner 1/2 PK R32 brand DAIKIN was 170 PSI for pressure and 1.64 A for current, where the measurement results of the pressure and current sensors have an average error of 10 measurements, namely 0,3 % for the G1 transmitter pressure sensor and 3,21% for the current sensor.

Abstract

The Markaz Hadith Bilal bin Rabbah Islamic Boarding School faces obstacles in the maintenance of operational vehicles, especially when there is damage to the components of the Accu head. The absence of human resources who have technical competence in the field of automotive electricity leads to dependence on external workshop services, which has an impact on increasing the operational costs of Islamic boarding schools. This problem also interferes with the smooth running of logistics activities and daily pesantren services. To answer these problems, lecturers and students of the Electrical Engineering and Mechanical Engineering Study Program, Pamulang University, conducted community service activities. This activity aims to increase the technical capacity of students and pesantren managers in independently diagnosing, treating, and repairing Accu heads using simple tools and materials. The activity was carried out with a participatory approach through interactive lecture methods, technical demonstrations, and hands-on practice in the field. The training materials are arranged appropriately so that they are easy for participants with non-technical backgrounds to understand. The evaluation was conducted using descriptive analysis techniques based on the pre-test and post-test results and qualitative observation of the participants' involvement during the training. Twenty participants attended this training. The analysis showed that as many as 65% of participants experienced a significant improvement in conceptual understanding and practical skills after participating in the training. These findings show the effectiveness of the activity in equipping participants with basic vehicle electrical skills. In general, this activity contributes to increasing the technical independence of Islamic boarding schools and opens up opportunities for developing skills-based entrepreneurship in the Islamic boarding school environment.

Abstract

The availability of electrical energy is one of the important factors during learning activities. However, because the electrical system can be said to be very complicated, starting from the generator center all the way to the consumer, there will most likely be a disruption that causes the flow of power to the consumer to be cut off. One of the factors that affect includes environmental factors, maintenance and other factors, so that the learning process is slightly hampered. The purpose of this research is to maintain electricity supply by automatically switching sources and utilizing renewable energy as a reserve for lighting students' practice rooms. Therefore, a system is needed that automatically regulates the switching of primary sources to backup sources. Automatic Transfer Switch or ATS is a device that automatically switches the main power source from PLN to a backup source such as solar panels by setting the time using Time Delay Relay (TDR). TDR functions to regulate the duration of the power source change operation to meet load needs, especially on small loads such as student practice rooms with a voltage of 220 Volts in one language. The advantage of this system is that it is able to automatically switch electricity supply between PLN and Solar Panels with a controlled time lag. The research method involves the installation of electrical panels and Solar Panels using Solar Charger Controller or SCC, Inverter devices. At the time of the study, the adjustment of the TDR setting to set the time lag on the ATS. SCC settings are carried out to obtain Inputs and Outputs in the optimal battery charging process where the measurement results show that When the load of the incandescent lamp is increased from 50Watt to 300Watt, the current increases from 4.47A to 25.2A, while the voltage decreases from 11.7V to 9.8V. In conclusion, the greater the load, the solar panel voltage decreases and the current increases. The results of the study show that the implementation of the automatic transfer switch system is able to automatically switch the electricity supply between PLN and Solar Panels with a controlled time lag.

Abstract

High-rise buildings such as the World Trade Center Jakarta generally have high inductive electrical loads, so that their reactive power consumption is large and the power factor decreases below the SPLN standard (≤0.85), resulting in increased power losses and operational costs. This study aims to measure the power factor value before and after repairing the detuned reactor and capacitor on the capacitor bank panel, compare the results of field measurements with ETAP simulations, and assess the feasibility of the installed capacitor bank and determine the difference in the results of the ETAP simulation between measurements and load calculations on the World Trade Center building. The methods used include literature review, field observations on the LVMDP panel, MCC and capacitor bank, discussions with supervisors, data collection of current, voltage, kW, kVAR, kVA and cos φ using Lovato DCRG8 and ampere clamp, and load simulation using ETAP software. The results show that the cosφ value increased from 0.70 to 0.95 (an increase of 35.71%), the compensated reactive power reached 204 kVAR (Lovato), 282.6 kVAR (tang ampere), and 415 kVAR (ETAP simulation), with a power factor or cosφ = 0.95. In conclusion, the replacement of detuned reactors and capacitors effectively improves the power factor in the WTC Jakarta Building, reduces reactive loads, and the ETAP simulation results are consistent with field measurements, so that the capacitor bank installed in the WTC building is declared effective in reducing reactive currents, thereby reducing kVAR, kVA loads and improving the efficiency of the electrical system distribution for better energy management

Abstract

Kinerja sistem humidifier industri sangat bergantung pada ketersediaan aliran air yang stabil guna mempertahankan kelembapan udara sesuai kebutuhan. Penelitian ini mengembangkan sistem kontrol otomatis berbasis Internet of Things (IoT) untuk mengatur bypass valve pada pompa suplai tangki humidifier dengan tujuan meningkatkan stabilitas tekanan dan efisiensi penggunaan energi listrik. Sistem ini menggunakan mikrokontroler ESP32 yang dikoneksikan dengan aplikasi Blynk untuk pemantauan dan pengaturan tekanan air secara real-time. Dua skenario pengujian yang dilakukan terdiri dari: skenario pertama tanpa kontrol otomatis, dan skenario kedua dengan sistem kontrol otomatis. Hasil eksperimen menunjukkan bahwa tekanan air pada skenario pertama kurang stabil dengan rata-rata 11,18 psi, sedangkan skenario kedua menunjukkan peningkatan kestabilan dengan rata-rata tekanan 12,32 psi. Selain itu, konsumsi daya listrik pada skenario kedua lebih efisien, ditunjukkan dengan perbedaan arus antar fase sebesar 8–9% dibandingkan skenario pertama. Temuan ini mengindikasikan bahwa penerapan kontrol otomatis berbasis IoT mampu meningkatkan stabilitas tekanan air serta mengurangi konsumsi energi, yang secara keseluruhan berkontribusi terhadap efisiensi operasional sistem humidifier. The performance of an industrial humidifier system is highly dependent on the availability of stable airflow to maintain air humidity as needed. This study develops an Internet of Things (IoT)-based automatic control system to regulate the bypass valve on the humidifier tank supply pump in order to improve pressure stability and efficiency of electrical energy use. This system uses an ESP32 microcontroller connected to the Blynk application to monitor and regulate air pressure in real time. Two test scenarios were carried out, namely, the first scenario without automatic control and the second scenario with an automatic control system. The experimental results showed that the air pressure in the first scenario was less stable, with an average pressure of 11.18 psi, while the second scenario showed increased stability, with an average pressure of 12.32 psi. In addition, the consumption of electrical power in the second scenario was more efficient, as indicated by the difference in current between phases of 8–9% compared to the first scenario. These findings indicate that the application of IoT-based automatic control can improve air pressure stability and reduce energy consumption, which overall contributes to the operational efficiency of the humidifier system.
