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

PT. Sinar Kristal Nusantara currently only relies on driver experience in determining distribution routes without special studies, which causes delays in the delivery of crystal ice products due to irregular distribution flow. This study aims to determine the optimal distribution route with the shortest distance to make deliveries more efficient and timely. The methods used are Nearest Neighbor and Tabu Search algorithm. The process starts by classifying the initial route using Saving Matrix, then determining the optimal route through Nearest Neighbor and Tabu Search. The results showed that this method resulted in a total mileage of 31.05 km with a travel time of 37.26 minutes, more efficient than the current route which reached 63.90 km with a time of 75 minutes. Tabu Search proved to be a superior optimization method because it produced a shorter route than using Nearest Neighbor alone. In conclusion, the combination of Nearest Neighbor and Tabu Search can improve the efficiency of crystal ice distribution at PT. Sinar Kristal Nusantara.

Abstract

The design of an Arduino Uno-based water acidity (pH) monitoring device for boilers at Steam Power Plants (PLTU) fundamentally provides significant assistance to field technicians who monitor water acidity levels daily. Currently, the water sampling process for boilers is generally conducted manually, which is inefficient because the water quality in the boiler fluctuates constantly, while sampling is only performed every eight hours. The objective of this research is to design a pH monitoring device for boilers and display the sensor readings on an LCD monitor. The methodology used in this study involves experimental design for both hardware and software. The hardware utilizes a pH sensor with a pH 4502C module as the input, which is then processed by an Arduino and displayed on the LCD. The results indicate that the pH sensor system using the pH 4502C module can achieve a reading accuracy of up to 95.6%, and the device is considered to be in compliance with national standards. During detection, the sensor monitors pH levels between 7.0 and 11.0; if the level exceeds the 11.0 threshold, the buzzer will deactivate.

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 .
