Abstract

Perkembangan Internet of Things (IoT) memungkinkan pengembangan alat bantu mobilitas yang tidak hanya memberikan peringatan terhadap kondisi lingkungan, tetapi juga menyediakan informasi lokasi kepada pendamping. Penelitian ini bertujuan merancang dan menguji tongkat bantu jalan tunanetra berbasis ESP32-C3 Mini yang terintegrasi dengan sensor ultrasonik HY-SRF05, water sensor, GPS NEO-6M, buzzer, motor getar, push button, Wi-Fi, dan Telegram. Metode penelitian menggunakan pendekatan perancangan dan pengujian sistem yang meliputi perancangan perangkat keras dan perangkat lunak, perakitan purwarupa, pengujian sensor, pengujian aktuator, pengujian GPS, pengujian komunikasi IoT, serta pengujian konsumsi daya. Hasil pengujian sensor ultrasonik pada jarak acuan 20–120 cm menunjukkan selisih pembacaan 3–4 cm dengan error 3,33–15%. Water sensor mampu mendeteksi kondisi air dan mengaktifkan motor getar, sedangkan buzzer memberikan pola bunyi yang berubah sesuai kedekatan objek. Push button dapat digunakan sebagai pemicu fungsi darurat setelah ditekan sekitar empat detik. GPS mampu memperoleh koordinat pada area terbuka dan mengirimkan data melalui Telegram. Pengiriman data jarak dan lokasi menunjukkan delay sekitar dua detik pada kondisi jaringan pengujian. Sistem dapat berfungsi sebagai purwarupa alat bantu mobilitas yang memberikan umpan balik nonvisual dan monitoring lokasi. Keterbatasan utama berada pada ketergantungan komunikasi terhadap Wi-Fi, variasi akurasi GPS, dan kebutuhan optimasi catu daya.

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.

Abstract

Sistem pemantauan untuk mesin pemotong Loopco di PT. Lion Metal Works Tbk. sebelumnya dilakukan secara konvensional, sehingga membatasi akses real-time ke data kondisi mesin dan menunda deteksi dini kerusakan. Studi ini mengembangkan sistem pemantauan kinerja mesin berbasis Internet of Things (IoT) menggunakan ESP32 yang terintegrasi dengan PLC Omron CP2E-N40DRA untuk mendukung pemeliharaan prediktif. Sensor PT100 digunakan untuk memantau suhu bantalan motor, sedangkan PZEM-016 mengukur parameter listrik. Data PLC meliputi panjang material, penghitung produksi, status mesin, dan jam kerja. Data dipertukarkan melalui Modbus RTU melalui RS-485 dan dikirim dari ESP32 ke ThingsBoard Cloud menggunakan MQTT. Metode eksperimental diterapkan melalui desain sistem, implementasi, validasi sensor, pengujian komunikasi, pengujian dasbor, dan evaluasi alarm. PT100 menghasilkan kesalahan rata-rata 0,65% dan akurasi 99,35%, sedangkan PZEM-016 menghasilkan kesalahan rata-rata 0,49% dan akurasi 99,51%. Komunikasi PLC-ESP32 mencapai tingkat keberhasilan 100% dengan waktu respons 60–63 ms. Transmisi MQTT juga mencapai keberhasilan pengiriman 100%, dengan penundaan terukur sekitar 1,24 ms dan tanpa kehilangan paket. Dasbor ThingsBoard berhasil menampilkan data waktu nyata dan tren historis. Aturan alarm mengklasifikasikan kondisi mesin menjadi Normal, Peringatan, dan Kritis berdasarkan kondisi operasi dasar. Sistem yang dihasilkan menyediakan pemantauan waktu nyata terintegrasi dan mendukung pengambilan keputusan pemeliharaan berdasarkan kondisi sejak dini.

Abstract

The rapid industrial growth in strategic zones demands a highly reliable electricity supply system. However, existing 500 kV Extra High Voltage transmission lines equipped with traditional ACSR conductors often face critical challenges, including limited transmission capacity, significant power losses, and excessive sagging due to material degradation. This study investigates the effectiveness of reconductoring a 12.13 km segment of a 500 kV transmission network using High-Temperature Low-Sag (HTLS) Aluminium Conductor Composite Core (ACCC) technology. Employing a qualitative descriptive method with a case study approach, data were gathered through field observations and technical documentation analysis. The results demonstrate that replacing the legacy ACSR conductors with ACCC Amsterdam conductors significantly enhances network performance without the need for new tower infrastructure. Specifically, the transmission capacity increased from 1500 A to 2250 A (a 1.5-fold improvement), while power losses were reduced by up to 10%. Furthermore, the ACCC conductors maintained voltage stability with drops not exceeding 5% and operated safely at a maximum operating temperature of 160°C, effectively mitigating sagging issues. The reconductoring process proved to be a highly cost- and time-efficient strategy compared to building new transmission lines. In conclusion, utilizing ACCC conductors for 500 kV transmission upgrades provides a robust solution to optimize power supply reliability and efficiency, fully supporting the escalating energy demands of heavy industrial areas

Abstract

The need for internet data access to support several existing services and applications continues to increase, along with increasing users annually as projected by the international standard of telecommunications, namely 3GPP and 3GPP2. The current utilization of 4G technology has not been optimal and not sufficient enough to meet the increasing number of customers in data access that require faster data rates and greater capacity generated from mobile user video traffic and social media networks on smartphones, mobile PC and tablet. The increasing number of data communication users, which impacted the greater the amount of data traffic generated in cellular mobile network systems. Beside that, mobile operators had to increase the number of cell sites (NodeB) in order to anticipate this huge volume of traffic data. Yet, with implementation of 4.5G (LTE-Advance Pro) technology enhanced network performance and network system’s capacity. Three of new features encompassed 32-component carriers (CC) that combined downlink using carrier aggregation to increase the capacity, 256-QAM modulation on the downlink and 64-QAM on the uplink, and MIMO systems FDD 4T4R / TDD 8T8R to increase the overall bitrates. From the test result done by some operators, the technology utilization increased the downlink data speed from the standard 4G LTE speed, which achieved 1 to 4 Gbps by combining all these technologies. It’s 10 times comparing to the standard LTE. LTE-Advanced Pro would have been greater capacity with 640 MHz bandwidth and made the use of its frequency spectrum more efficient
