Abstract

The quality of pond water is an important factor in ensuring the health and sustainability of the organisms within it. Internet of Things (IoT) technology has enabled the development of sophisticated and effective monitoring systems to monitor water quality in real-time. One important parameter that needs to be monitored is the temperature of the pond water, as unstable temperatures can harm aquatic organisms. To obtain good quality and disease-free fish at normal times, the optimal temperature for catfish fry is around 28˚C - 30˚C. Manual monitoring or using thermometer measuring instruments is still very traditional and limited to the ability of supervisors to carry out continuous monitoring and may cause delays in detecting significant temperature changes. This research aims to analyze the monitoring system of pool water quality based on temperature by utilizing IoT technology. The proposed system uses a DS18B20 temperature sensor that is wirelessly connected to the IoT network. The temperature data collected in real time will be uploaded to Firebase for storage and further analysis. Through the development of this IoT-based pond water quality monitoring system, it is expected to increase efficiency and reliability in monitoring pond water quality. From the monitoring conducted for approximately 24 hours, the temperature in the fishpond is 28°-30°. After analyzing with direct monitoring, the good temperature is at night at 18.00-00.00 WIB. In conjunction with a standard thermometer, resulted in an average temperature sensor error rate of less than 5%, highlighting the reliability of the IoT technology in real-time environmental monitoring.

Abstract

Pembangkit listrik tenaga surya (PLTS) adalah jenis pembangkit listrik yang menghasilkan listrik dari energi surya. Panel surya menghasilkan listrik langsung dari cahaya. Aeroponik adalah teknik pertanian tanpa tanah di mana larutan nutrisi disemprotkan ke akar tanaman melalui semprotan nutrisi yang halus di udara. Sistem aeroponik beroperasi menggunakan energi yang dihasilkan oleh panel surya. Baterai menyimpan energi yang tidak langsung, sehingga dapat digunakan pada malam hari atau pada hari yang kurang terang. Proses pertama yang dilakukan pada penelitian ini adalah merancang sistem monitoring lingkungan aeroponik berbasis IoT dimana komunikasi data nya melalui blynk untuk mengirimkan hasil monitoring kepada pengguna. Berdasarkan analisis dan hasil perhitungan yang telah dilakukan, untuk mendukung sistem monitoring lingkungan aeroponik berbasis IoT dengan beban total 73,284 watt, diperlukan 1666 panel surya dengan kapasitas 100 WP tanpa beban dan 1669 panel surya dengan beban serta kapasitas baterai sekitar 1055.3 kWh, dengan asumsi efisiensi sistem 75% dan penyinaran matahari 5 jam per hari.

Abstract

Navigation is the main issue for autonomous mobile robot due to its mobility in an unstructured environment. The autonomous object tracking and following robot has been applied in many places such as transport robot in industry and hospital, and as an entertainment robot. This kind of image processing based navigation requires more resources for computational time, however microcontroller currently applied to a robot has limited memory. Therefore, effective image processing from a vision sensor and obstacle avoidances from distance sensors need to be processed efficiently. The application of neural network can be an alternative to get a faster trajectory generation. This paper proposes a simple image processing and combines image processing result with distance information to the obstacles from distance sensors. The combination is conducted by the neural network to get the effective control input for robot motion in navigating through its assigned environment. The robot is deployed in three different environmental setting to show the effectiveness of the proposed method. The experimental results show that the robot can navigate itself effectively within reasonable time periods.

Abstract

The development of home automation technology and smart rooms is growing rapidly, especially through the utilization of voice commands to control electronic devices. This research develops a voice command-based smart room system using an ESP32 module connected with Google Assistant and the IFTTT platform for device control in an electrical engineering laboratory. The system allows users to turn on or off devices such as lights and TVs with just a voice, improving the efficiency and convenience of laboratory operations. The implementation using ESP32 as a Wi-Fi microcontroller, which activates relays to control devices, was tested in real laboratory conditions that have challenges in the form of electromagnetic interference and noise. The test results showed a fast and accurate system response of up to 90%, although there were some failures in high noise conditions. The system has the potential to be an effective automation solution to support learning and practical processes in electrical engineering laboratories, with further development needed to improve the system's robustness against noise interference.

Abstract

Pemanfaatan energi terbarukan semakin gencar diimplementasikan sebagai upaya pencapaian target net zero emission pada tahun 2060. Salah satunya adalah pengembangan teknologi lampu otomatis yang dapat beroperasi secara efisien berdasarkan kebutuhan pencahayaan. Penelitian ini merancang sistem lampu berbasis fuzzy logic dan Arduino Uno untuk meningkatkan efisiensi energi. Sistem ini memanfaatkan sensor cahaya BH1750 yang dipasang di luar ruangan untuk mendeteksi intensitas cahaya lingkungan, serta sensor tegangan untuk memantau kondisi baterai pada sistem tenaga surya (PLTS). Data dari kedua sensor tersebut diolah menggunakan fuzzy logic untuk menentukan jumlah lampu yang perlu dinyalakan, sehingga konsumsi energi dapat dioptimalkan. Pengujian dilakukan selama 4 jam dengan memantau parameter lux, tegangan, arus, dan penggunaan energi. Hasil penelitian menunjukkan bahwa sistem mampu menyesuaikan pencahayaan secara otomatis sesuai dengan kondisi lingkungan, mengurangi pemborosan energi, dan meningkatkan fleksibilitas. Dengan memanfaatkan energi surya, sistem tidak hanya hemat energi tetapi juga mandiri dan ramah lingkungan. Penerapan teknologi semacam ini merupakan langkah strategis dalam mendorong transisi energi bersih sekaligus mendukung target net zero emission di masa mendatang.

Abstract

Lengan Robot Berjari telah banyak digunakan pada industri maupun penggunaan dalam bidang pendidikan. Perancangan lengan robot berjari dibagi atas dua bagian, bagian pengendali pada lengan manusia (Transmitter) dan Lengan Robot Berjari (Reciever). Lengan robot berjari ini berbasis mikrokontroler dengan menggunakan ATMega 32A pada pengendali dan ATTiny 2313 pada robot serta dengan media transmisi wireless menggunakan KYL 1020U. Jari-jari robot dikendalikan oleh Flex Sensor Spectra Symbols 4.5 inch Series SEN 08606 dengan memanfaatkan resistivitas dari Flex Sensor tersebut. Flex Sensor adalah sensor lengkung yang fleksibel secara fisik sehingga dapat mengikuti pergerakan jari manusia. Range resistansi sebuah Flex Sensor berkisar 10 KΩ – 40 KΩ. Flex Sensor sebagai pengendali lengan robot berjari memiliki persentase (%) kesalahan (error) sebesar 13% - 37,7%. Setiap perubahan kelengkungan sebesar 1o pada Flex Sensor berbanding lurus dengan kenaikan nilai resistivitas sebesar 113 Ω. Kenaikan nilai resistansi terhadap derajat kelengkungan Flex Sensor akan berbanding terbalik dengan kenaikan nilai arus yang dihasilkan untuk menggerakan jari robot dengan motor mini servo HS-81. Dibutuhkan keseimbangan perancangan antara mekanik dan elektronik untuk menghasilkan kinerja lengan robot berjari yang maksimal
