The wireless communication network has seen rapid growth, especially with the widespread use of smartphones, but resources are increasingly limited, especially indoors. Femtocell, a spectrum-efficient small cellular network solution, faces challenges in distributed power control (DPC) when deployed with distributed users, impacting power levels, and causing interference in the main network. The aim of this research is optimizing user power consumption in co-tier femtocell networks by using the user power treatment. This study proposed the Distributed Power Control (DPC) variation methods such as Distributed Constrained Power Control (DCPC), Half Distributed Constrained Power Control (HDCPC), and Generalized Distributed Constrained Power Control (GDCPC) in co-tier femtocell network. The research examines scenarios where user power converges but exceeds the maximum threshold or remains semi-feasible, considering factors like number of users, distance, channel usage, maximum power values, non-negative power vectors, Signal-to-Interference-plus-Noise Ratio (SINR), and link gain matrix values. In Distributed Power Control (DPC), distance and channel utilization affect feasibility conditions: feasible, semi-feasible, and non-feasible. The result shows that Half Distributed Constrained Power Control (HDCPC) is more effective than Distributed Constrained Power Control (DCPC) in semi-feasible conditions due to its efficient power usage and similar Signal-to-Interference-plus-Noise Ratio (SINR). Half Distributed Constrained Power Control (HDCPC) is also easier to implement than Generalized Distributed Constrained Power Control (GDCPC) as it does not require user deactivation when exceeding the maximum power limit. Distributed Power Control (DPC) variations can shift the power and Signal-to-Interference-plus-Noise Ratio (SINR) conditions from non-convergence to convergence at or below the maximum power level. We concluded that the best performance of Distributed Power Control (DPC) is Half Distributed Constrained Power Control (HDCPC).

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. Pengembangan lebih lanjut dapat dilakukan dengan mengintegrasikan sistem ini dengan platform IoT berbasis cloud untuk pemantauan yanglebih canggih dan efisien.Kata Kunci : Sistem keamanan, Internet of Things (IoT), ESP- 32, Sensor, Modul GPS Neo-6M, SIM 800 L
