2024-05-30T15:16:54+07:00

Portable Solar Water Pump is an alternative to renewable energy that can convert solar radiation into the form of electrical energy used to pump rice field irrigation water. Solar radiation promotes increased photovoltaic absorption, leading to improved battery life time performance. Solar cells have a high efficiency value if photons from sunlight can be absorbed as much as possible. This research aims to design a Portable Solar Water Pump. After that analyze the forecasting of solar radiation Watt/ in the next hour starting from 08.00-13.00 then predicted at 14.00 using the Feed-Forward Neural Network (FFNN) method. And get an error value of 2.6. With the highest radiation value of 1285,6 Watt/ .

Health technology has become more efficient thanks to telecommunications and information technology. One of the utilizations is IoT detecting a person's body temperature condition. This research aims to produce a tool that can classify human body temperature by implementing fuzzy logic methods and the Internet of Things so that early prevention can be carried out against hyperthermia and hypothermia sufferers and can be used as advice for further examination to doctors. The phases in this study are analysis requirement, system design, implementation, and testing. The tools incorporated in this system are intended to measure body temperature and can classify the measured body temperature into specific categories. This research utilizes the Sensor Proximity E18-D80nK to detect the presence of an object concerning the sensor. Additionally, the system employs MLX90614 sensors for temperature measurement. The results of this research are that the use of the DHT22 sensor for measuring room temperature and the MLX80614 sensor for non-contact body temperature respectively produces a high level of accuracy, namely 98.22% and 98.29%. In addition, the implementation of the fuzzy logic algorithm succeeded in achieving 100% accuracy in classifying body temperature data, showing the effectiveness of this method in detecting human body temperature.

VSAT (Very Small Aparture Terminal) Network Performance In Data Transmission Seismic In The BMKG Region III

2024-02-16T23:00:26+07:00

Abstrak – Kondisi geografis Indonesia yang terdiri dari banyak pulau, daerah pegunungan, dan lautan apabila dilakukan komunikasi terestrial maka akan sulit dilakukan. Serta untuk membangun komunikasi tersebut memerlukan biaya yang sangat besar. Untuk mengatasi permasalahan tersebut dikembangkanlah teknologi Very Small Aparture Terminal (VSAT) dengan memanfaatkan Satelit sebagai sistem komunikasinya. Badan Meteorologi Klimatologi dan Geofisika (BMKG) juga memanfaatkan VSAT sebagai media transmisi data seismik. Dalam transmisi data dari satelit ke stasiun bumi menempuh jarak yang sangat jauh. Sehingga dalam transmisi data tersebut membutuhkan waktu yang tidak kecil. Dalam penelitian ini akan dianalisis mengenai latency, satelit downstream, dan satelit upstream sebagai performansi dari jaringan VSAT. Hasil pengamatan latency pada jaringan VSAT di Balai Besar MKG Wilayah III menunjukkan nilai di bawah 750 ms yang artinya masih kategori baik. Serta nilai satelit downstream yang semakin besar dan nilai satelit upstream yang semakin kecil berarti bahwa performansi jaringan VSAT semakin bagus. Secara garis besar performansi VSAT untuk transmisi data seismik di Balai Besar MKG Wilayah III dalam kondisi bagus.

Abstract – Indonesia's geographical conditions consist of many islands, mountainous areas and oceans, if terrestrial communication is carried out it will be difficult. And to build this communication requires very large costs. To overcome this problem, Very Small Aparture Terminal (VSAT) technology was developed using satellites as the communication system. The Meteorology, Climatology and Geophysics Agency (BMKG) also uses VSAT as a seismic data transmission medium. In transmitting data from satellites to earth stations over very long distances. So the data transmission requires quite a bit of time. In this research, latency, downstream satellites and upstream satellites will be analyzed as the performance of the VSAT network. The results of latency observations on the VSAT network at the MKG Region III Center show a value below 750 ms, which indicates that is still in the good category. And the larger the downstream satellite value and the smaller the upstream satellite value, it means that the performance of the VSAT network is getting better. In general, VSAT performance for transmitting seismic data at the MKG Region III Center is in good condition.

Design and Build an IoT Based Reading Room Visitor Monitoring System for the Department of Electrical Engineering

2024-01-16T15:25:22+07:00

The reading room is one of the places frequented by students. Students can use this room for various activities such as reading books, looking for materials, independent study, and other activities. The increasing number of visitors in the room can affect the availability of space which can cause inconvenience between visitors and limited facilities that can hamper the activities to be carried out. Therefore, regular monitoring of the room is needed so that the room can be used optimally. In this study, researchers proposed a reading room visitor monitoring system tool majoring in IoT-based electrical engineering. This tool utilizes a single microcontroller, namely NodeMCU Esp8266 with the features offered, namely monitoring the number of visitors entering and leaving the room, the total number of visitors who are in the room, and the status of room availability. This tool is also equipped with red and green indicator lights as an indicator of room availability and a buzzer as an alarm if the room condition is full. The monitoring results are displayed on the LCD and utilize the IoT platform, namely in the application that displays monitoring results via a smartphone that can be accessed regularly. The sensors used in this study include Ultrasonic sensors and PIR sensors. The purpose of this research is to produce IoT-based reading room visitor monitoring tools and test the performance of the tools. In this study, the visitor monitoring tool that was made worked well with an average error of 0.031.

Air Pollution Quality Monitor (CO, CO2, PM2.5) at Surabaya State University

2023-12-29T15:01:01+07:00

Exposure to air pollution inhaled every day greatly impacts health. Air pollution occurs anywhere, including in the environment of Surabaya State University. Air pollution originates from vehicle emission gases, combustion activities, and other sources. Due to limitations in obtaining air quality information within Surabaya State University, this study aims to facilitate monitoring of air pollution quality (CO, CO₂, PM2.5) within Surabaya State University to improve health quality. This air pollution monitor can measure the concentration of CO, CO₂, and PM2.5 where the MQ-7 sensor detects CO (carbon monoxide) gas concentrations, the MQ-135 sensor detects CO₂ (carbon dioxide) gas concentrations, DSM501A sensors detect PM2.5 (particulate) concentrations, and the use of IoT as a medium for delivering air pollution quality information that can be accessed through air pollution monitoring websites anywhere and anytime. The pollution monitoring tool has a fairly good performance in measuring the quality of air pollution (CO, CO₂, PM2.5) in the environment of Surabaya State University, with an average MQ-7 sensor reading accuracy of 87%, an average MQ-135 sensor reading accuracy of 96.44% and an average DSM501A sensor reading accuracy of 90.68% and can send air pollution monitoring results to the website in real-time.
