Abstract

Motor induksi merupakan sebuah motor yang sulit untuk dikontrol sehingga memerlukan kecepatan yang sinkron dikarenakan adanya perubahan beban yang dinamis yang dikendalikan adalah arus torsi sedangkan arus medan dibuat konstan. Dengan demikian didalam paper ini adalah mengimplementasikan metode kontroler PID adaptif dengan motor induksi menggunakan Matlab yang meng- koordinasikan kecepatan dua beban decouple dengan motor induksi tiga phasa dimana didesain dan direalisasikan sebuah kontroler PID adaptif Self Tuning Regulator (STR) untuk pengaturan kecepatan motor induks itiga fasa menggunakan softwere Mtlab dan Mikrokontroler AVR Atmega16 sebagai input dan output dari plant dengan komunikasi menggunakan serial rs232. Hasil menunjukkanbahwasetelahdilakukan koordinasi system dengan masing-masing motor yang diberikan controller neural dan FOC didapatkan hasil kecepatan motor yang secara bertahap memberikan kecepatan yang sinkron sehingga dapat disimpulkan system ini dapat bekerja dengan baik untuk memperlambat respon plant.

Abstract

The implementation of the construction of Unit Kegiatan Mahasiswa (UKM) room at the Faculty of Engineering, Cenderawasih University is a form of support for the appeal of the Ministry of Education, Culture, Research, and Technology (KEMENDIKBUD RISTEKDIKTI) as stated in the Guidelines for the Implementation of Student Organization Activities No. 0241/E/E2/KM.09.00/2022. Student activities under student organizations are a forum for students to develop their capacity as students in the form of aspirations, initiations, or positive, and creative ideas through participation in various relevant activities. The purpose of this service activity is to provide a UKM building for each Department Student Association (Himpunan Mahasiswa Jurusan–HMJ) as a forum for implementing student activities at the Faculty of Engineering, Cenderawasih University. The realization of the UKM building construction activities was carried out through four stages of work. First, budget design by setting a format of 80% of the total cost for the main building fund and 20% for emergency funds. Second, the design of the UKM building is adjusted to the dedicated fund. Third, procurement of materials and building worker services. Fourth, the SME building construction process. The contribution of this activity is the design and construction of the UKM building at the Faculty of Engineering, Cenderawasih University as a means for students to channel their aspirations, to develop their science and technology abilities and organizational potential.Keywords: Student activity units; student centers; learning students; student organizations; student affairs

Abstract

One of the consequences of load imbalance is the flow of current in the neutral wire. The current flowing on the neutral wire will cause heat, so indirectly, the consequences of load imbalance contribute to losses for PLN as a producer of electricity. The purpose of this study is to the percentage of transformer load imbalance, the percentage of losses due to neutral current in the transformer neutral conductor. The method used in this research is collecting distribution transformer load data on the Melati extent. From the results of the data analysis, it is obtained that the largest percentage of load imbalance occurs in transformer AB-225 with a loading percentage of 64.95% LWBP and 65.74% WBP. Based on the results of the analysis the total percentage of losses due to the neutral current on the neutral conductor of the transformer is 7.89% and 9.76% LWBP and WBP, respectively.

Abstract

Tulisan ini menjelaskan metode untuk melakukan lokalisasi optic disc. Metode yang digunakan untuk melokalisasi optic disc ditentukan oleh keberadaan pembuluh darah vertikal dan daerah paling terang pada citra retina. Pengujian metode menggunakan 56 citra fundus retina dengan resolusi spasial sebesar 605x700. Hasil pengujian menunjukan tingkat keberhasilan lokalisasi optic disc sebesar 96%. Terdapat juga perbandingan hasil lokalisasi optic disc, antara metode deteksi pembuluh darah vertikal yang dikembangkan pada penelitian ini, dengan metode fuzzy convergence pada penelitian terdahulu. Pengujian menggunakan 56 citra fundus retina yang sama. Hasil perbandingan menunjukan selisih deteksi optic disc antara kedua metode adalah sebesar 25 piksel.

Abstract

This research focuses on the design and implementation of an Arduino-based mobile robot equipped with an ESP32 camera. The primary goal is to develop a mobile manipulator prototype that can be controlled remotely via a mobile or web application. This project also aims to identify the required electronic components, understand their integration with the ESP32 module, and evaluate the ESP32's advantages over the Arduino Uno. The method used is a development research approach, involving literature review on robotics, Arduino programming, and image processing with the ESP32-CAM and ESP8266. The research stages include system design, component selection, mechanical design, and electronic circuit design. Programming code development is carried out iteratively, starting with basic functions such as motor movement and image capture, to more complex functions such as simple object recognition. Testing of the mobile manipulator prototype demonstrates that the hardware and software developed are functional. The robot is capable of motion control, image transmission from the ESP32-CAM to a smartphone, and the ESP8266 can transport light objects. However, there are several challenges, such as overheating of the ESP32-CAM and ESP8266 modules, as well as potential malfunctions in the SG90 servo motor and DC gearbox motor.
