Abstract

The research discusses the implementation of a fast charging system on Lithium-Ion batteries by comparing the performance of conventional Buck Converters and Synchronous Buck Converters. Charging is carried out using constant current (CC) and constant voltage (CV) methods with set points of 4A and 16.8V as the targets used, and is equipped with sensors to monitor voltage and current during the charging process. The system is controlled by the Adaptive Neuro Fuzzy Inference System (ANFIS) which is useful for maintaining charging stability at one battery specification with a full capacity of 4.2V voltage and 4A current. Test results show that ANFIS is able to maintain filling parameters within safe limits. In addition, the Synchronous Buck Converter provides better efficiency than conventional Buck Converters in terms of efficiency and controlling voltage fluctuations, so it is more optimal for use in Lithium-Ion battery fast charging systems.

Abstract

Program pengabdian masyarakat ini dilaksanakan di Desa Wisata Kembangbelor, Kecamatan Pacet, Kabupaten Mojokerto, yang memiliki potensi besar sebagai destinasi wisata unggulan. Permasalahan utama yang dihadapi adalah pengelolaan sampah di area parkir yang mengurangi kenyamanan pengunjung dan citra kebersihan desa. Kegiatan dilakukan dengan pendekatan Participatory Action Research (PAR) melalui edukasi pengelolaan sampah, pemasangan poster edukatif, penyediaan tempat sampah organik dan anorganik, serta pelaksanaan forum group discussion bersama masyarakat dan pengelola wisata. Hasil kegiatan menunjukkan peningkatan kesadaran masyarakat terhadap pengelolaan sampah dan berkurangnya sampah tercampur di area wisata. Keterlibatan aktif masyarakat dalam setiap tahap kegiatan menunjukkan efektivitas pendekatan partisipatif dalam menciptakan perilaku ramah lingkungan. Program ini berkontribusi terhadap penguatan citra Desa Kembangbelor sebagai destinasi wisata yang bersih, edukatif, dan berkelanjutan

Abstract

Object detection is one of the most popular applications among young people, especially among millennials and generation Z. The use of object detection has become widespread in various aspects of daily life, such as face recognition, traffic management, and autonomous vehicles. The use of object detection has expanded in various aspects of daily life, such as face recognition, traffic management, and autonomous vehicles. To perform object detection, large and complex datasets are required. Therefore, this research addresses what object detection algorithms are suitable for object detection. In this research, i will compare the performance of several algorithms that are popular among young people, such as YOLOv5, YOLOv7, and YOLOv8 models. By conducting several Experiment Results such as Detection Results, Distance Traveled Experiment Results, Confusion Matrix, and Experiment Results on Validation Dataset, I aim to provide insight into the advantages and disadvantages of these algorithms. This comparison will help young researchers choose the most suitable algorithm for their object detection task.

Abstract

Penerapan Visual servoing dengan metode color recognition merupakan sistem yang mengklasifikasikan objek berdasarkan warna dan posisi objek yang terdeteksi melalui kamera untuk menggerakkan servo pada robot lengan. Sistem ini menggunakan Huskylens sebagai kamera yang digunakan untuk mendeteksi warna dan posisi dari sebuah objek dan robot lengan untuk memindahkan objek yang sudah terdeteksi melalui kamera. Dari hasil pengujian, penerapan visual servoing robot lengan dengan metode color recognition dapat berfungsi dengan respon  rata-rata 0,9 detik untuk mengejar objek ketika objek tidak berada di posisi pengambilan dan berfungsi dengan baik untuk mengambil dan meletakkan objek dengan dua warna yaitu biru dan merah ketika berada di posisi pengambilan dengan persentase akurasi deteksi objek 98% serta persentase akurasi pengambilan dan pemindahan objek 100% melalui rentang jarak deteksi minimal 18 – 22 cm diatas objek dan dengan pencahayaan yang terang.

Abstract

The rainy season is an obstacle for everyone, especially drying shoes, because rain can hinder the process of drying shoes. Currently, shoes are still dried using the conventional method, namely by utilizing the sun's heat. The next development is a system for drying shoes using gas fuel, but it has the potential for fire. In this final project, a shoe drying system is designed which is controlled using PI control according to a specified setpoint to dry shoes when exposed to rain or at night. To get the appropriate room temperature, the output voltage from the heater needs to be controlled using the Digital Firing Angle. The ignition angle is regulated by the Digital Firing Angle circuit. To maintain the temperature conditions in a stable condition, namely 65°C, this tool is controlled using PI (Proportional Integral) control. This dryer is designed for a maximum of 1 pair of wet shoes. With final humidity results in the drying room ≤ 20%RH. With this final project, it can dry shoes in rainy conditions in 94 minutes for synthetic leather shoes and 104 minutes for leather shoes.
