Abstract

Smart agriculture systems require soil sensors capable of monitoring environmental conditions in real-time and with high accuracy. This research presents the design and fabrication of a soil conductivity sensor prototype using a composite material of Polyaniline (PANI) and Graphene Oxide (GO). The prototype is designed with a two-electrode structure based on copper layers, where the active PANI–GO layer functions as a conductive path that responds to soil moisture and ion levels. The PANI–GO composite was synthesized through a polymerization method and then applied to copper-based electrodes. Test results showed detectable changes in resistance according to variations in soil moisture content, where resistance values decreased as the soil became moister and more fertile. Moisture levels were adjusted to 10%, 20%, 30%, and 40% for two soil types: fertile and infertile. These results indicate the potential of the composite material as a simple soil sensor that can be further developed for Internet of Things (IoT) applications in agriculture. This study serves as a foundational step in the development of low-cost, flexible, and easily integrated conductive soil sensors.

Abstract

Breakdown time is one of the events that must be minimized, even eliminated in every production process in the manufacture sector. PT X as one of the national steel producers also strives to optimize the production process, considering that the capital needed to produce steel is relatively high. Breakdown time needs to be analysed properly to get the right and accurate solution. One of the tools that can be used is fishbone diagram. Based on the data obtained, it is known that the two most dominant obstacles that occurred during the December - May period occurred in the Crop Shear and Flying Shear areas. In the Crop Shear area, it is known that the motor trips due to indications of overspeed, while in the Flying Shear area the motor works abnormally due to indications of a dead oil pump. Maintenance and repair actions are then designed based on the results of the analysis obtained to anticipate the original occurrence in the future through corrective and preventive maintenance.

Abstract

Attendance systems that still rely on manual input require more processing time due to the absence of an automatic identification mechanism, resulting in less efficient attendance recording. This study aims to design and develop an employee attendance system based on Radio Frequency Identification (RFID) and the Internet of Things (IoT) integrated with a web-based application. The research employed the Research and Development (R&D) method using the ADDIE development model. The system was developed using an ESP32 microcontroller, an RFID RC522 Reader, PHP, and MySQL, while IoT technology was utilized to transmit attendance data to the server via the internet. The test results indicate that all system functions operated successfully, including RFID card identification, data transmission, database storage, and attendance information display on the website. Furthermore, the developed system improved attendance processing efficiency by reducing the attendance time from 15–20 seconds to 2–5 seconds. Therefore, the proposed RFID and IoT-based attendance system can serve as an effective and efficient alternative for managing employee attendance.

Abstract

Pengelolaan sampah masih menjadi permasalahan di berbagai wilayah Indonesia akibat keterbatasan infrastruktur yang tidak sebanding dengan volume sampah yang dihasilkan. Tak jarang masyarakat melakukan pembakaran sampah secara terbuka sebagai solusi cepat, yang berpotensi menimbulkan pencemaran lingkungan dan gangguan kesehatan. Kegiatan ini mengembangkan incinerator skala kecil yang terintegrasi dengan sistem monitoring gas buang untuk mendukung proses pembakaran sampah yang lebih terkendali. Hasil pengujian menunjukkan incinerator mampu mencapai suhu maksimum 918 °C. Konsentrasi maksimum gas buang yang terukur adalah CO sebesar 21,7 ppm dan CO₂ sebesar 497,4 ppm. Nilai tersebut masih berada di bawah nilai ambang batas yang digunakan sebagai acuan. Hasil penelitian menunjukkan bahwa incinerator mampu membakar sampah pada suhu tinggi dengan konsentrasi CO dan CO₂ yang terukur masih dalam batas yang ditetapkan. Sistem yang dikembangkan berpotensi menjadi alternatif pengelolaan sampah skala kecil yang lebih terkendali.
