PENERAPAN SENSOR CJMCU101 UNTUK MENDUKUNG SISTEM SMART LECTURE ROOM

This study presents the design of a Smart Lecture Room system that utilizes light intensity sensors, specifically CJMCU101. These sensors are installed in each classroom to monitor the ambient conditions. The implementation of the designed system was carried out in the classrooms of the Udayana University Electrical Engineering Study Program. To achieve this goal, the classroom utilized by the Electrical Engineering Study Program of Udayana University was divided into two classes (DH101 and DH102) and a sensor was installed in each class as an IoT device. The IoT devices are connected to a Raspberry Pi Access Point, where the data from the sensors is stored and monitored using the Thinger.io platform. The validation of the sensor testing is carried out by comparing the results obtained from the sensors with the results obtained from a thermohygrometer measurement. This research produces a prototype smart lecture system, applied to a classroom mockup, that employs IoT devices, sensor databases, and sensor monitoring. The data from each sensor's detection is stored in the LAMP database, which employs Linux, Apache, MySQL, and PHP. The Thinger.io platform monitors the values of each sensor. A variation in accuracy between the sensor and measuring instrument results in a difference in their values. The CJMCU101 light intensity sensor has an average accuracy of 93.48% compared to the measuring instrument on DH101. The average accuracy of the sensor value compared to the measuring instrument on DH102 is 95.96%.

Peningkatan Kewaspadaan Masyarakat Kelurahan Jaticempaka, Bekasi Terhadap Banjir dengan Alat Pendeteksi Banjir

Floods occur due to rainfall that is high enough so that the water level rises above normal limits and overflows into residential areas. Floods can occur regardless of time, so there is a need to increase public awareness of floods. In the environment around the Krisnadwipayana University, namely, Jaticempaka Village, Bekasi, which is one of the public service partners, floods often occur due to the overflow of the Sunter River. Based on surveys and monitoring, the lack of public awareness of Jaticempaka Village, Bekasi, regarding flood disasters due to the lack of a system or device that can detect the high water level in the Sunter River, which causes flooding. Therefore, lecturers and students of the Electrical Engineering Study Program, Faculty of Engineering, Krisnadwipayana University were inspired to participate with carrying out public service, namely by making and installing a flood detection device that can detect water level levels at the Sunter River using an Atmega 8535 microcontroller and an ESP8266 MCU node. It is hoped that by installing the flood detection device, the public of Jaticempaka Village, Bekasi, can obtain information about the water level of the Sunter River, so that can increase public awareness of flood disasters.

Improvement of Skills for Mu'allimin International Class Upper Secondary Level Students Through Line Follower Robot Training

Madrasah Mu'allimin Muhammadiyah Yogyakarta is a private religious-based educational institution. This campus has a superior class, namely Mu'allimin International Class Upper Secondary (MIC US). This class has 35 students and is divided into Upper Secondary A and Upper Secondary B classes. Even though Madrasah Mu'allimin has organized robotics extracurricular activities, in this MIC UP class all students cannot participate in these activities because the location of this class is far from the robotic site. MIC UP students' interest in robotics is quite high. Therefore, the students need to be given short training to improve their knowledge and skills in constructing robots. To realize this activity, Madrasah Mu'allimin collaborated with the Electrical Engineering Study Program at Universitas Muhammadiyah Yogyakarta (TE Study Program UMY), specifically line follower robot training. This activity is planned to be held for 1 day, starting with a pretest, delivering robotics material, building line follower robots, testing robots on the track, and closing it with a post-test. This activity was assisted by 2 international students from the TE Study Program UMY, coming from North Sudan and Qatar.
