Abstract

Abstract : Design and Construction of a Kaidipang Vocational School Student Attendance System Using WEB-Based RFID and ESP 8266. This research aims to build a web-based RFID and ESP8266 attendance system. This system uses RFID cards to identify students and store attendance data digitally. The methods used in this research are literature study, observation and experiment. The research results show that the RFID and web-based ESP8266 attendance system can read and process data quickly and accurately, and student attendance is recorded correctly. This system can also operate consistently and does not experience significant disruption. The implementation of an RFID-based and web-based ESP8266 attendance system at SMK Negeri 1 Kaidipang is expected to increase the efficiency and effectiveness of recording student attendance data at SMK 1 Kaidipang, which currently still uses conventional attendance, resulting in time inefficiencies, proneness to loss of absence data, and the use of a lot of paper. and attendance printing costs.

Abstract: Design and Construction of an FM Radio Trainer System for Student Learning at the Electronics and Telecommunications Laboratory, Faculty of Engineering, Gorontalo State University. This research aims to build an FM Radio Trainer as student learning in the Basic Telecommunication Engineering course. The method used in this research is literature study and experimentation. The FM Radio Trainer design uses IC LA1260 as an FM Tuner and IF Amplifier, IC LA3361 as a Multiplexer and Demodulator, IC TDA 2004 as a Power Amplifier. The test results were carried out to measure the parameters VAntenna, VCC, IF, AFC (IC LA1260), MPX, Demodulator, VRight, VLeft (IC LA3361), VRight input Output, VLeft Input Output (IC TDA2004). The test results carried out on RRI Pro1 FM 101.8MHz Radio broadcast show that the results are in accordance with the tuning frequency. The gain of the output signal (A) occurs 5 times that of the input signal and the sound intensity level is 13.9 dB.

Abstract

The increasing plastic waste volume in Gorontalo City is not balanced by a good management system, making people choose to burn their waste in open space. Not only makes a bad scene, this burning emits dangerous gases such as CO2 that contributes to poor air quality and climate change. This study has developed an environmentally friendly incinerator with a stacked condenser system that emits less CO2 gas. This incinerator consists of three main components: a combustion zone, as the place where plastic waste is burned; a chimney, for the flowing of gas; and stacked condensors, for cooling and keeping the gas before emitting it out. We test the incinerator with and without condensors based on the CO2 emission from 20 minutes' burning of 1.5 kg of plastic waste. The results show that an incinerator with a stacked condensor system can significantly reduce CO2 gas emissions by 18.88% more than an incinerator without condensors. This implies that incinerator with stacked condensors can be an alternative way to reduce CO2 gas from open-space waste burning on a small scale.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengimplementasikan sistem absensi siswa berbasis teknologi Radio Frequency Identification (RFID) yang terintegrasi dengan notifikasi WhatsApp secara otomatis kepada orang tua. Program ini dilaksanakan di SMK Negeri 5 Gorontalo sebagai upaya modernisasi sistem administrasi sekolah dan peningkatan keterlibatan orang tua dalam memantau kehadiran siswa. Metode pelaksanaan meliputi survei kebutuhan, perancangan alat dan sistem, instalasi, pelatihan penggunaan, serta uji coba lapangan. Hasil kegiatan menunjukkan bahwa sistem RFID mampu mencatat kehadiran siswa secara cepat, akurat, dan real-time. Notifikasi WhatsApp berhasil dikirim otomatis setiap kali siswa melakukan absensi, sehingga orang tua dapat langsung mengetahui kehadiran anak di sekolah. Guru dan staf tata usaha menyatakan sistem ini sangat membantu dalam proses rekap data absensi serta mengurangi penggunaan kertas. Secara keseluruhan, kegiatan ini memberikan solusi teknologi tepat guna yang efisien, ramah lingkungan, dan aplikatif, serta berpotensi untuk direplikasi di sekolah lain sebagai bentuk dukungan terhadap transformasi digital di dunia pendidikan. This community service program aims to implement a student attendance monitoring system based on Radio Frequency Identification (RFID) integrated with automatic WhatsApp notifications to parents. The activity was conducted at SMK Negeri 5 Gorontalo as part of efforts to modernize school administration systems and enhance parental involvement in monitoring student attendance. The implementation method included needs assessment, system and device design, installation, user training, and field testing. The results showed that the RFID system successfully recorded student attendance quickly, accurately, and in real time. WhatsApp notifications  were  automatically  sent  each  time  a  student  checked  in,  allowing parents to instantly receive attendance updates. Teachers and administrative staff reported that the system significantly simplified the attendance recap process and reduced paper usage. Overall, this program provided an efficient, environmentally friendly, and applicable technological solution, supporting digital transformation in schools. The developed system has strong potential to be replicated in other educational institutions as an example of appropriate technology application in vocational education.

Abstract

A resistivity meter can find out resistivity depth of rock structure, sediment layer, or the depth of water surface. However, the resistivity meter that is often used requires manually recording of the measurement results before inputting them into the processing data software, and this creates many steps in the geoelectric survey. This is because acquiring a resistivity meter with a data storage system entails additional costs, due to its expensive price. Consequently, many of the resistivity meters currently found in laboratories or used in the field are not equipped with a data storage system. This research aims to design a resistivity meter with a data storage system for measurement results, based on Arduino Mega 2560, for laboratory scale. The used sensors were INA219 currents sensor and voltage sensor. In addition, the tests were carried out to determine the level of accuracy of each sensor and testing for data storage system of measurement result. This research employed Schlumberger configuration in the development of resistivity meter. This research has successfully developed a resistivity meter device with a current sensor accuracy level of 97.28% using the INA219 sensor, and a voltage sensor accuracy level of 97.44%. It is noteworthy that the accuracy level is high, and the device is capable of performing readings effectively. This research has successfully designed a resistivity meter which has a measurement data storage.
