Abstract

Teknologi Radio Frequency Identification (RFID) telah banyak digunakan dalam sistem keamanan, logistik, dan otomatisasi karena kemampuannya melakukan pembacaan data secara nirkontak. Namun, performa pembacaan RFID sangat dipengaruhi oleh kondisi lingkungan, khususnya keberadaan benda penghalang antara pembaca dan tag. Penelitian ini bertujuan untuk menganalisis pengaruh jenis benda penghalang terhadap jarak pembacaan dan keberhasilan deteksi tag RFID menggunakan modul RFID RC-522 yang beroperasi pada frekuensi 13,56 MHz. Objek penelitian difokuskan pada pengujian beberapa jenis benda penghalang yang umum dijumpai sehari-hari dan dikelompokkan ke dalam dua kategori utama, yaitu benda non-konduktif (kertas, plastik, kayu, kain, kaca, dan air) serta benda konduktif (logam aluminium). Metode penelitian dilakukan secara eksperimental melalui pengujian pembacaan RFID pada variasi jarak 0–6 cm dengan interval 1 cm. Setiap pengujian dilakukan sebanyak lima kali percobaan pada setiap jenis benda penghalang untuk memperoleh nilai rata-rata jarak maksimum pembacaan dan persentase keberhasilan deteksi. Hasil penelitian menunjukkan bahwa pada kondisi tanpa benda penghalang, modul RFID RC-522 mampu membaca tag secara stabil hingga jarak 6,0 cm dengan tingkat keberhasilan 100%. Benda non-konduktif seperti kertas, plastik, kayu, dan kain hanya menyebabkan penurunan jarak pembacaan sebesar 5–15% dengan tingkat keberhasilan deteksi di atas 95%. Sebaliknya, air menurunkan jarak pembacaan secara signifikan hingga rata-rata 1,2 cm dengan keberhasilan deteksi 40%, sedangkan logam aluminium sepenuhnya menghalangi pembacaan tag dengan tingkat keberhasilan 0%. Hasil ini membuktikan bahwa sifat konduktivitas dan permitivitas benda penghalang berpengaruh signifikan terhadap performa pembacaan RFID RC-522.

Abstract

Indonesia has targeted a 31.89% reduction in greenhouse gas emissions through its own efforts and up to 43.20% with international support by 2030. One of the main strategies in achieving this target is through ecosystem restoration, particularly forests and peatlands, which play a crucial role in carbon sequestration. However, restoration efforts still face challenges such as limited field data, delays in detecting ecosystem changes, and minimal technology integration in monitoring. To address these issues, this study proposes the use of an Internet of Things (IoT)-based monitoring system and smart sensors as an innovative solution. The research method used was a Literature Review, a research approach based on the collection, evaluation, and synthesis of various relevant scientific works to build a conceptual understanding of a topic. The results indicated that IoT implementation in Indonesia faces significant challenges, with network infrastructure in remote areas, limited implementation costs, uneven technical skills, and data security issues being the main obstacles. Furthermore, successful implementation requires institutional support, regulations, and local community participation to optimize the use of IoT-based monitoring systems.

Abstract

A Power Breaker is a mechanical switch that is able to open to allow current to flow under normal conditions and close when there is a disturbance under abnormal conditions, such as a short circuit current disturbance. Damage to the Power Breaker has a considerable influence on the operation of the electric power system, resulting in losses and the operating system of the electric power being disrupted. For this reason, it is necessary to periodically test Power Breaker performance in order to meet operating standards, improve reliability, guarantee quality, and maintain the continuity of electric power distribution. This research was limited to testing before and after the Power Breaker 20 kV Net Cubicles Maintenance located at the Senayan PLTMG Substation during February 2023 in the form of contact resistance testing, Insulation resistance testing, simultaneity testing, and trip relay testing. By testing the performance of the Power Breaker, it is hoped that it can prevent malfunctions that result in damage to the Power Breaker and other components at the Senayan PLTMG Substation

Abstract

The acceleration of technological transformation through artificial intelligence (AI) and the crypto economy is widening the digital divide across various regions. This research aims to analyze the relationship between telecommunications infrastructure and technological literacy in overcoming barriers to digital access. To date, previous research has tended to examine these two aspects in isolation, leaving gaps in our understanding of integrated solutions. By applying qualitative methods to policy documents and scientific literature, this research finds that the digital divide is a multidimensional phenomenon arising from the nonlinear interaction between infrastructure access, cognitive capabilities, and patterns of technology use.

Abstract

The development of industrial automation systems demands improvements in safety, efficiency, and production process quality, particularly in the conveyor line assembling area, which is at risk of process failures due to work sequence errors, improperly installed components, and human error. This study aims to analyze the implementation of a Programmable Logic Controller (PLC)-based interlock system as a preventive measure against production process failures in the conveyor line assembling area. The research employed a quantitative experimental approach through field observation, literature review, interviews, interlock logic design using Ladder Diagrams on an Omron CP1L PLC, and system testing using a photoelectric sensor as the main input. The test results showed that the photoelectric sensor was able to consistently detect objects up to a distance of 20 cm with an 80% success rate and an average response time of 0.443 seconds. The interlock system was able to provide appropriate responses in 8 out of 10 test scenarios, equivalent to an 80% success rate, including automatically stopping the conveyor when a disturbance occurred and activating a warning alarm. The implementation of the interlock system also succeeded in reducing the percentage of non-conforming (NG) products from 1.88% to 0.20%, representing an 82.8% reduction out of a total of 13,700 production units over four weeks of observation. Overall, the effectiveness level of the interlock system reached 99.91%, with 13,688 units successfully passing through all process stages without disruption. Based on these results, it can be concluded that the PLC based interlock system is effective as an automatic safety system for improving the reliability, safety, and efficiency of the production process in the conveyor line assembling area.
