Improvement of Student Attendance System for Recording Student Surface Body Temperature Based on Internet of Things
No full textStudent attendance is a system used for tracking student activity in school. Many methods are used to develop student attendance systems, such as Quick Response (QR) Code systems, Radio Frequency Identification (RFID) systems, fingerprint systems, and so on. The COVID-19 pandemic has driven technological development, especially in the student attendance system. Measuring human surface body temperature has become a protocol that must be done before entering school. Student attendance systems need to expand the function not only for attendance but also for monitoring student surface body temperature. This research aims to improve student attendance systems by adding surface body temperature measurements and recording during student presence. Recording data can be done by using the internet of things. Student presence data will be sent to school databases throughout the internet. This system uses RFID technology for student presence and a non-contact thermal sensor for temperature measurement. According to data research, non-contact thermal sensors provide a temperature reading with an average error of 1.69%, a minimum error value of 0.96%, and a maximum error value of 2.57% with a range error value of 0.35°C - 0.95°C. RFID test shows that the optimum distance for the system to read an RFID card is 0 - 2cm. The System also successfully sent presence data to the student school database through the internet. This study concludes that developed systems can track student attendance by recording the student\u27s surface body temperature while in presence. Further work will be focused on managing data networks if this system is used with many users in the school
BLDC Motor Drives with A Programmable Simplified C-Block to Generate Accurate Six-Step PWM Based on STM32 Microcontroller
No full textThis paper presents a digital implementation of a brushless direct current motor (BLDCM) drive with a six-step pulse width modulation (PWM) using a programmable simplified C-block based on the STM32 microcontroller. The implementation is conducted through the PSIM simulation platform, which is commonly used for power electronics and motor control. This approach combines the benefits of using a programmable simplified C-block for precise and flexible programming with the PWM concepts of the STM32 microcontroller. The PWM method used on the BLDCM drive is the unipolar upper PWM technique (H~PWM_L~ON). The performance of the PWM implementation is analyzed in detail, including the accuracy of the PWM generation using a Fast Fourier Transform (FFT), the gating of the IGBTs in the three-phase inverter, and the effect of the duty cycle on the BLDCM\u27s speed, phase voltage, and phase current

An evaluation of the implementation of study-from-home policy in senior high school during Covid-19 pandemic
No full textThe increase in Coronavirus Disease-19 in Indonesia has prompted the central and regional governments to issue a study-from-home (SFH) policy through the Minister of Education and Culture Circular Letter Number 4 of 2020. The policy aims to reduce activities in schools but uses a meaningful curriculum. The purpose of the evaluation is to see the SFH policy implementation related to teaching and learning activities. The collection of information and data, interviews, and group discussion forums were conducted through online meetings, including video conferencing and other social media. This policy implementation was analyzed in the aspects of context, input, process, and product. The study involved 2,862 respondents, consisting of 60 people from the Education Office, 284 school principals, 861 teachers, 677 students\u27 parents, and 980 students. Evaluation results for each aspect show that: (1) in terms of context, policymakers in the regions have followed up Governor\u27s decrees and the SFH program (78.33%); (2) in terms of input, schools have prepared 17% of infrastructure and the level of teacher ability is 41.64%; (3) in terms of process, 49.56% of learning is carried out online; and (4) in terms of product, 88% teachers have assessed learning outcomes. Thus, the SFH policy has been carried out optimally, but some learning factors are not going well due to limited cell phones, low teacher competence in using applications, and unavailability of the Internet network in some schools. The SFH implementation at the provincial government level has been carried out effectively and efficiently, but in schools, online learning is still found to be uneven
