Abstract

This study aims to design a multisensor observation system, develop a microcontroller-based prototype with ESP8266 and RFID modules, and analyze the performance of the prototype. From the testing carried out by tagging each time students do activities, the client tag data will be sent to the server, and the results are displayed PLX-DAQ. With the 50 tag cards that have registered the IDs of each student, it shows that those who attend the schedule will be given the logic "1" (otherwise logic "0"), and attendance data will be obtained by calculating the number of attendance of students in four types of activities in four locations. The data is transmitted to Data-loggers through two configurations, namely Data-logger as the client (indirect), and Data-logger as a server (direct). From the two configurations, it was found that the configuration of Data-logger as a server had a performance of 19.08% better than Data-logger as a client. From the data processing, it was found that the highest activity of students was the interest in the activities of language institutions (95.92%), followed by religious activities (95.83%), teaching and earning activities (93.88%), and reading (79.59 %)

Abstract

COVID-19 merupakan penyakit yang diakibatkan oleh virus corona (Cov-2) sehingga mengakibatkan pemerintah dan lingkungan masyarakat harus menerapkan protokol kesehatan seperti menggunakan masker, cuci tangan menggunakan sabun, jaga jarak, dan protokol pencegahan penyebaran penyakit COVID-19 lainnya. Salah satu protokol yang harus diterapkan dalam kehidupan sehari-hari adalah dengan memeriksa suhu tubuh dan pengecekan penggunaan masker ketika memasuki atau menggunakan fasilitas umum. Umumnya setiap gedung atau bangunan pemerintah maupun swasta menggunakan jasa petugas keamanan untuk memeriksa orang yang akan memasuki gedung, namun hal tersebut tidak sepenuhnya dijalankan dalam kondisi krisis seperti saat ini. Hasil penelitian didapatkan bahwa algoritma haar cascade dapat mendeteksi masker (dengan tidak mendeteksi mulut) pada masker medis dan non medis yang tidak bermotif gambar wajah, namun sistem mendeteksi mulut pada masker bermotif gambar mulut pada itensitas cahaya di atas 175 lux. Hasil pembacaan sensor MLX90614 didapat Galat dengan nilai minimum -1.28°C dan maksimal 1,66°C terhadap multimeter digital. Pengujian keseluruhan menunjukkan sistem mendeteksi suhu dan masker dan memberikan akses dengan membuka kunci pintu dengan mengaktifkan selenoid.

Abstract

The two-axis Sun tracker with the tetrahedron geometry that has been developed has an error percentage of 31.26% and a speed of 0.063 m/s. The value of the accuracy and speed is still considered low for tracking sunlight in open space conditions. The research aims to improve the accuracy and speed of the tetrahedron tracker sun. The method used to obtain tracking accuracy is to implement a control system that forms a tracking system using the proportional integral derivative (PID) control and modifies the sun's light by adding a sun tracker and laser to the top of the tetrahedron structure. In addition, the motor used to measure the state of the horizontal and vertical axes is the DC Stepper type. The results obtained indicate the level of accuracy of the modified sun tracker system is 0.650 on the X-axis and 0.540 on the Y-axis with a speed of 0.091 m / s. From these results, it can be concluded that the sun tracker modification is able to track sunlight properly with an average tracking error rate of 0.78% on the X-axis and 4.67% on the Y axis.

Abstract

The research discusses about the energy saving techniques in the design of data logger devices based on AVR microcontroller for monitoring parameters of the air temperature and sunlight intensity in the visible light spectrum. These energy reduction techniques include hardware aspects such as the use of the minimum system, peripherals power supply control and software such as sleep-mode. When the intensity of sun light increases, the interrupt pin will activate the system, otherwise the system is in a state of sleep-mode. The electrical energy consumption of the data logger is continuously observed and recorded on an external memory (SD card) in real-time as so the 24 hours energy consumption can be known and the long-term-used energy can be predicted. Based on the results of measurements and calculations it is known that it takes energy of 8.23 Wh to turn the data logger for 24hours. With this reduction technique, the data logger energy consumption can be reduced by 68.5%.Keywords: data logger, energy saving, sun, sleep mode, interrupt

Abstract

Utilization of renewable energy from solar panel systems is increasingly being applied, but until now its utilization has not been maximized. The movement of the sun caused by rotation of the earth and cloudy condition should be taken into account to maximize the electrical energy in solar panels. In this study, a concept to calculate the movement of a two-axis sun tracker is proposed by using a combination of two controller methods, i.e. Proportional Integral Derivative (PID) and Fuzzy logic known as Fuzzy-PID (F-PID). To follow the movement of the sun, the LDR sensor is used as an input to light as well as output used to drive 2 units servo for x-axis and y-axis. Sun tracker that is used is based on tetrahedron geometry and uses three Light Dependent Resistor (LDR) sensors as input. Input and output components are connected to the Atmega 328P by using a combination of Fuzzy logic and PID programs (F-PID). Fuzzy logic programming is first performed on the Matlab application using Fuzzy Inference System (FIS), then converted into an Arduino-based programming language. The sun tracker movement and the voltage received by the solar panel will be stored into the SD card using a data logging module. Adjusting the sun tracker movement using the combined Fuzzy logic and PID method intends to maximize the electrical energy received by the solar panel. The results showed that the F-PID method obtained the maximum voltage of 5.3 V, a maximum current of 0.11 A, and a maximum power of 0.61 W.

Abstract

Monitoring the output parameters of a solar module is required for assessing its performance under real operating conditions. This paper presents a new technique for monitoring the output parameters i.e. current and voltage of solar module directly under real operating conditions. In this new monitoring technique, the output parameters of a solar module can be directly processed in real time condition and their results are displayed in a graph. The monitoring system is developed using microprocessor Arduino Atmega 328P and equipped with calibrated current and voltage sensors, a data acquisition system which is integrated directly into an Excel spreadsheet using the PLX-DAQ application program and a memory card for backup. The monitoring system is connected to a computer using a RS232 serial port. The collected data is saved directly into a spreadsheet and plotted in real time. This technique provides an easy access to the collected data for further analysis.

Abstract

Tofu is a soy-based food that is popular in Indonesia. One of the supporting factors is that it has high nutritional value and low price. Tofu is produced by micro, small, and medium enterprises (MSMEs) in all provinces in Indonesia, including in the region of Aceh. Based on the results of observations, the tofu production process still predominantly uses human labor, starting from the washing process to the cutting process. This activity is carried out every day with a high repetition rate. If this is allowed to happen for a long time, workers will be exposed to the risk of musculoskeletal disorders. This study uses the Cornell Musculoskeletal Disorders (CMDQ) questionnaire to assess the workers' work posture and determine the level of occupational hazard risk using the Rapid Entire Body Assessment (REBA) method. The results of the distribution of questionnaires show that the body parts that experienced pain complaints were the shoulder (right dan left), upper back, upper arm (right and left), lower back, forearm (right and left), also wrist (right and left). It happens in the filtering process. The results of the assessment of work posture with the REBA method show the score of work posture in the filtering process is 13, which means that the filtering posture of workers has a very high risk and must be improved immediately.  The present research recommended additional intervention that includes engineering and administrative control methods for reducing those workers' complaints of muscle pain.
