Abstract

Kotak amal masjid sering menjadi target pencurian akibat sistem keamanannya yang masih konvensional. Oleh karena itu, penelitian ini bertujuanuntuk merancang sistem keamanan berbasis sensor getar SW-420 dan modul SIM 800L guna meningkatkan pengamanan kotak amal masjid. Sistem ini bekerja dengan mendeteksi getaran saat kotak amal digerakkan, yang kemudian memicu alarm buzzer serta mengirimkan notifikasi otomatis melalui Telegram pengurus masjid. Selain itu, sistem ini juga dilengkapi dengan modul GPS Neo-6M untuk melacak lokasi kotak amal secara realtime. Metode yang digunakan dalam penelitian ini meliputi perancangan perangkat keras dan lunak, integrasi sensor, serta pengujian sistem secara keseluruhan. Perangkat keras utama terdiri dari NodeMCU ESP-32 sebagai mikrokontroler, sensor getar SW-420, sensor ultrasonik, buzzer, modul SIM 800L, serta GPS Neo-6M. Pengujian dilakukan untuk mengukur efektivitas sensor dalam mendeteksi perubahan posisi dan getaran, serta kecepatan respons sistem dalam memberikan notifikasi. Hasil pengujian menunjukkan bahwa sistem bekerja dengan akurasi tinggi. Sensor getar SW-420 mampu mendeteksi kondisi "getar" dan "diam" tanpa kesalahan. Modul GPS Neo- 6M memiliki tingkat akurasi rata-rata 7,84 meter di beberapa lokasi pengujian. Notifikasi yang dikirimmelalui SIM 800L juga terbukti efektif dan dapat diterima dalam waktu yang singkat. Dengan fitur buzzer sebagai alarm lokal, sistem ini mampu meningkatkan kewaspadaan lingkungan terhadap potensi pencurian. Sistem keamanan yang dirancang telah memenuhi kebutuhan pengamanan kotak amal masjid dengan tingkat akurasi yang baik dan memiliki potensi untuk diterapkan secara luas guna mengurangi tindak kriminal di tempat ibadah.

Abstract

Dalam budidaya kelinci, , penting untuk memperhatikan faktor-faktor seperti suhu dan kelembapan udara di dalam kandang. Suhu dan kelembapan yang ideal akan menjaga kualitas bulu dan meningkatkan nafsu makan kelinci. Jika suhu terlalu tinggi dan kelembapan udara rendah, kelinci bisa kehilangan nafsu makan dan bulunya menjadi mudah rontok.Oleh karena itu dengan melaukan pengukuran kelembapan dalam kandang kelinci bertujuan untuk dapat dimonitor secara serial dengan komunikasi modbus. Sensor yang dipakai pada pengukuran suhu dan kelembapan adalah XY-MD02 dengan komunikasi RS485. Sensor XY-MD02 akan berkomunikasi dan diproses dengan menggunakan mikrokontroler ESP32. Sistem akan menampilkan data suhu dan kelembapan kandang. Hasil pengujian akan mendapatkan nilai suhu dan kelembapan pada serial monitor. Pada tanggal 23, suhu siang hari berkisar antara 33°C hingga 34°C dengan kelembapan 64.2% hingga 66.9%, sementara pada sore hari suhu sekitar 30°C dengan kelembapan 73% hingga 74%. Pada tanggal 24, suhu siang hari berkisar sekitar 34°C dengan kelembapan 65%, dan pada sore hari suhu turun menjadi 28°C dengan kelembapan 84% hingga 85% akibat hujan. Dalam pengukuran selama dua hari ini, dapat disimpulkan bahwa kondisi cuaca sangat berpengaruh terhadap suhu dan kelembapan kandang. Suhu pada sore hari tanggal 24 lebih baik karena adanya hujan, yang membantu menurunkan suhu dan meningkatkan kelembapan secara signifikan.

Abstract

This study evaluates the feasibility of utilizing the 2100 MHz frequency band for the implementation of a Narrowband Internet of Things (NB-IoT) network in the Purwokerto region using two schemes, In-Band and Guard-Band.  This research aims to provide recommendations for the most efficient scheme to support the implementation of Smart Metering based on Advanced Metering Infrastructure (AMI) in the area. The method used is simulation based on radio planning software, considering the number of existing sites, network capacity, and coverage.  The key performance parameters analyzed include Reference Signal Received Power (RSRP), Signal to Interference plus Noise Ratio (SINR), and throughput. The simulation results show that both schemes can be used for the implementation of the NB-IoT network in Purwokerto, but the Guard-Band scheme provides better performance with RSRP of –94.39 dBm, SINR of 6.61 dB, and throughput of 14,947 bps, compared to the In-Band scheme, which results in RSRP of –99.39 dBm, SINR of 6.61 dB, and throughput of 14,623 bps. Based on these results, the Guard-Band scheme is recommended for implementation because it provides superior performance in the RSRP and throughput parameters, which are crucial for supporting the quality of Smart Metering AMI services. The contribution of this research is to provide new insights into the implementation of NB-IoT in Purwokerto and compare two frequency allocation schemes within the 2100 MHz band. Keywords: NB-IoT, Smart Metering, In-Band, Guard-Band, 2100 MHz.

Abstract

The deployment of 5G networks in provincial capitals such as Semarang presents challenges related to high user demand, coverage requirements, and investment costs. This research aims to evaluate the network coverage and techno-economic feasibility of 5G implementation in Semarang. Using an urban macro propagation model, two scenarios were analysed: Uplink Non-Line-of-Sight (UL-NLOS) and Downlink Non-Line-of-Sight (DL-NLOS). The UL-NLOS scenario requires 11 sites, while the DL-NLOS scenario requires 6 sites to achieve full coverage of the city. The average Synchronization Signal–Reference Signal Received Power (SS-RSRP) is −125.74 dBm, indicating sufficient signal strength. A techno-economic analysis reveals that the UL-NLOS scheme yields an NPV of IDR 292.566.473.678 with an IRR of 110.25%, while the DL-NLOS scheme yields an NPV of IDR 300.000.000.000 with an IRR of 115.38%. These results confirm that both scenarios are technically feasible and economically viable. The findings suggest that 5G deployment in Semarang can yield profitable returns, providing valuable insights for mobile operators in planning future investments.

Abstract

This research is expected to be the beginning of the initial design for the implementation of 5G technology in Indonesia especially in Area Sawahan, Surabaya based on the coverage area with the frequency of 3.3 GHz. Performance analysis with line-of-sight (LOS) conditions using propagation model urban macro (uMa) according to the recommendation of 3GPP (3rd Generation Partnership Project) TR 38.901. This research based on four scenarios, outdoor-to-outdoor (O2O) for downlink and uplink, and outdoor-to-indoor (O2I) scenario for uplink and downlink. Performance of 5G network simulated using Atoll 3.4 and shown the pathloss values ​​of 105.405 dB for uplink and 101.405 dB for downlink. The performance results in the O2O scenario for the uplink direction require 5 gNodeB and 8 gNodeB in the downlink direction. In the O2I scenario, the uplink direction requires as many as 6 gNodeB and the downlink direction as much as 9 gNodeB. The simulation parameters analyzed in this research are based on the signal strength received by the user (SS-RSRP) and signal quality (SS-SINR). The best result of SS-RSRP in the O2I uplink scenario is -89 dBm and the SS-SINR parameter in the O2O scenario is 0.93 dBm. These results show that in the city of Sawahan a 5G system can be applied.

Abstract

Currently, cellular technology is advancing into the 5G era, which can support data speeds up to 10 Gbps on the uplink side and 20 Gbps on the downlink side. This study aims to plan a 5G NR network by implementing the inter-band carrier aggregation (CA) method. CA is one of the techniques used to achieve high data speeds and to combine two or more radio frequency bands. The primary cell uses band n40 at 2300 MHz with a 40 MHz bandwidth, while the secondary cell uses band n78 at 3500 MHz with a 100 MHz bandwidth. The area that we used for this network design is Agung Podomoro Land (APL) Tower Central Park area in West Jakarta. The propagation model used Urban Macro. Testing process is carried out by comparing the results between using CA and not using CA on the SSRSRP, SS-SINR, and data rate parameters. Simulation results show an average increase in each parameter after the inter-band carrier aggregation method is applied. The SS-RSRP parameter increased by 0.05% with a value of -82.02dBm, the SS-SINR parameter increased by 0.77% with a value of 15.71dB, and the data rate parameter significantly increased by 241.33% with a value of 803.66 Mbps. This proves that implementing the carrier aggregation method can improve the quality and capacity of the network, particularly the data rate, by maximizing the use of the bandwidth and resource block produced by the combination of component carriers.
