Abstract

Penelitian ini bertujuan untuk melakukan analisis User Experience siswa terhadap ruang kelas berbasis metaverse. Ruang kelas berbasis metaverse dikembangkan menggunakan Spatial.io untuk kelas mata kuliah Aljabar Linear pada Semester Genap Tahun Ajaran 2022/2023 di Institut Teknologi dan Bisnis Palcomtech. Metode pengukuran user experience menggunakan metode survei yang menggunakan User Experience Quistionnaire yang digunakan untuk mengukur daya tarik, kejelasan, efisiensi, ketepatan, stimulasi dan kebaruan. Pengukuran dilakukan  kepada siswa yang mengikuti pelajaran menggunakan ruang kelas berbasis metaverse unttuk mata kuliah Aljabar Linear. Tahapan penelitian terdiri dari lima kegiatan, yaitu perencanaan, membuat skenario dan penugasan, melakukan pemilihan responden,melaksanakan pengujian usabilitas, dan menganalisa hasil pengukuran. Jumlah siswa yang menjadi responden sebanyak 38 siswa.  Metode analisis yang digunakan adalah deskriptif kuantitatif. Berdasarkan hasil analisis User Experience menggunakan User Experience Quistionnaire diperoleh hasil untuk  daya tarik  sebesar 1,217, kejelasan 1,647, efisiensi 1,603, ketepatan 1,218, stimulasi 1.130 dan kebaruan 1,058. Berdasarkan hasil analisis dapat disimpulkan bahwa ruang kelas berbasis metaverse untuk mata kuliah Aljabar Linear telah memenuhi kriteria yang baik untuk semua variabel yang diukur.

Abstract

The workshop on cable-based and wireless networks with VLANs and routing using Mikrotik is one of the community service activities carried out by Lecturers at the Palembang Palembang Institute of Business Technology. The aim of this activity is to increase the skills of students at Muhammadiyah 1 Palembang Vocational High School. The activity will be carried out on Monday 8 January 2024. The implementation method uses lecture and practice methods. The training activity is divided into three parts, namely the first is a presentation about networks, VLANs and routing using a proxy, the second is practice in creating a network, VLAN configuration and routing using a proxy which is carried out alternately by the presenter and training participants and the third is an exercise as evaluation material to determine the participant's level of understanding. . The result of this activity is the increased ability of students at the Muhammadiyah 1 Palembang Vocational School Menangah regarding computer networks and VLANs. The implementation of this activity went well where the training participants were active and able to complete the exercises well and on time.

Abstract

Training on a Bluetooth-based lighting control system with Arduino Uno for students of SMA Xaverius 3 Palembang is one of the community service activities carried out by lecturers from the Palcomtech Institute of Technology and Business and lecturers from Lembah Dempo University. The purpose of this activity is to increase students' knowledge and abilities to utilize Arduino Uno for lighting control. The activity was carried out on Tuesday, November 11, 2025 in Room 3.2 of the Palcomtech Institute of Technology and Business, Palembang. The training was attended by 36 students. The implementation method was carried out by presentation and practice. The training activities were divided into three parts, namely the first presentation about Arduino Uno, the second practice of using Arduino Uno for control, the third exercise by students as an evaluation material to determine the level of understanding of participants. The results of this activity are to increase students' knowledge about Arduino Uno and its various benefits, one of which is for lighting control. This implementation went very well where the training participants actively participated in the activities from the beginning to the end and were able to carry out the exercise on using Arduino Uno for lighting control well and on time, which means that participants could understand the material presented well.

Abstract

This study focuses on optimizing electric vehicle (EV) battery recycling through the use of green chemical processes and circular economy principles. The research aims to enhance the recovery of valuable metals lithium, cobalt, and nickel from used lithium-ion batteries (LIBs) in an environmentally sustainable manner. Green solvents were employed as a safer alternative to conventional, toxic chemicals, minimizing hazardous waste emissions and improving the efficiency of the recycling process. Experimental results showed that the green solvent-based process achieved high recovery rates of 90% for cobalt, 87% for nickel, and 85% for lithium, with metal purity levels exceeding 95% for all three metals. The study also examined the scalability of the green solvent method, revealing its potential to offer more sustainable and cost-effective solutions compared to traditional methods, which typically involve high temperatures and toxic chemicals. Despite the promising results, challenges such as solvent recovery and the adaptation of the process for large-scale industrial applications remain. Nonetheless, the study demonstrates that integrating green solvent-based recycling into the global EV supply chain can significantly reduce environmental impacts, conserve resources, and support the transition to a circular economy. The findings highlight the potential of this recycling method to provide a more sustainable and efficient solution for EV battery recycling, ultimately contributing to the development of a more sustainable EV industry.
