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

The increasing demand for electricity and the global commitment to carbon reduction have encouraged higher education institutions to integrate renewable energy into campus infrastructures. However, most previous rooftop PV studies at Universitas Negeri Gorontalo (UNG) have been limited to single-building assessments or have not fully integrated spatial analysis with technical simulation. This study addresses this research gap by conducting a comparative analysis and system optimization of a rooftop photovoltaic (PV) installation at the Faculty of Engineering building using a combined Geographic Information System (GIS) approach and detailed technical simulation through HelioScope. The optimized design yields a total capacity of 368.79 kWp comprising 647 Canadian Solar 570W modules. Simulation results indicate an annual energy output of 486.5 MWh with a Performance Ratio (PR) of 95.8%, where PR represents the ratio of actual system performance to ideal irradiance conditions, and a solar access value of 99.2%. The economic assessment shows a payback period of 11.04 years under an export tariff of IDR 1,440/kWh. Furthermore, a comparative evaluation with two previous studies demonstrates significant improvements in both technical and economic aspects due to the integrated GIS and high-resolution simulation approach. The findings provide a valuable reference for advancing renewable energy implementation in educational institutions, particularly in designing efficient and sustainable rooftop PV systems.

Abstract

Rumah Susun Sederhana Sewa (Rusunawa) merupakan salah satu solusi pemerintah dalam menyediakan hunian layak dan terjangkau bagi masyarakat berpenghasilan rendah. Dengan konsep hunian vertikal, rusunawa mampu menampung lebih banyak keluarga dalam lahan terbatas, terutama di wilayah perkotaan yang padat penduduk. Namun, seiring bertambahnya penghuni dan aktivitas harian, konsumsi energi listrik di lingkungan rusunawa menjadi salah satu komponen biaya hidup. Hal ini cukup signifikan berdasarkan observasi awal dan wawancara singkat dengan beberapa penghuni di salah satu Rusunawa di wilayah Kec. Telaga Kabupaten Gorontalo, diketahui bahwa banyak penghuni belum memahami prinsip penggunaan listrik yang efisien dan aman. Sebagian besar penggunaan peralatan elektronik di rumah tangga dilakukan tanpa memperhatikan aspek efisiensi energi, seperti membiarkan perangkat elektronik menyala terus-menerus, penggunaan lampu yang tidak hemat energi, serta pengaturan sistem ventilasi dan pendingin udara yang tidak optimal. Berdasarkan survei awal, Rusunawa memiliki total 42 unit hunian tipe 36 yang terbagi dalam 3 lantai. Jumlah penghuni tercatat sebanyak 168 orang, yang berarti rata-rata satu unit dihuni oleh sekitar 4 orang .
