Abstract

This study aims to evaluate the quality of 2G and 4G networks on Telkomsel operators in Gunung Talang District and Danau Kembar District, Solok Regency, West Sumatra. This research was conducted using the drive test method using TEMS Pocket and TEMS Discovery devices for network data collection and analysis. The 2G network measurements were conducted based on Rx Level and Rx Quality parameters. In contrast, the 4G network was evaluated based on RSRP (Reference Signal Receive Power) and SINR (Signal Interference to Noise Ratio) parameters. The measurement results on the 2G network show that the average Rx Level is at -85.1 dBm, with very poor signal quality reaching 27.14%, while the network quality based on Rx Quality is classified as excellent with an average value of 0.9 dB, which reaches 82.21%. On the 4G network, the average RSRP was -101.7 dBm with a good signal dominance of 30.68%, but the network quality based on SINR was lower, with an average value of 12.3 dB, where 46.98% of the signal was classified as fair. In addition, several bad spot areas were found to be affected by natural obstacles such as hills, cliffs, and tall trees that block the signal. The recommendation from this research is to optimize the nearest site to improve signal quality in these areas, especially to reduce overshooting problems that occur in certain sectors. This research is expected to be a reference for operators in improving network quality in the areas studied

Abstract

Integrasi Internet of Things (IoT) dengan cloud computing meningkatkan kapasitas penyimpanan, pemrosesan, dan analisis data, tetapi juga memperluas permukaan serangan karena data melewati perangkat, jaringan, gateway, broker, antarmuka layanan, dan infrastruktur cloud. Perlindungan kanal seperti Transport Layer Security (TLS) dapat mengamankan komunikasi pada setiap hop, namun tidak selalu mempertahankan kerahasiaan payload ketika koneksi diterminasi pada komponen perantara. Penelitian ini bertujuan menganalisis pendekatan keamanan data end-to-end pada sistem IoT berbasis cloud melalui kajian literatur terstruktur. Literatur peer-reviewed periode 2020–Agustus 2026 diseleksi berdasarkan relevansi terhadap ancaman, enkripsi dan integritas, autentikasi, manajemen kunci, kontrol akses, cakupan perlindungan payload, serta overhead implementasi. Dua belas studi substantif digunakan sebagai dasar sintesis komparatif dan tematik. Hasil kajian menunjukkan bahwa perlindungan pada tingkat payload dapat melengkapi TLS, terutama pada arsitektur publish–subscribe ketika broker tidak seharusnya memperoleh plaintext. Pendekatan yang paling menonjol mencakup lightweight authenticated encryption, lightweight block cipher, dan conditional proxy re-encryption. Tantangan utama meliputi overhead komputasi dan komunikasi, kompleksitas siklus hidup kunci, skalabilitas, serta keterbatasan sumber daya perangkat. Kajian ini menegaskan pentingnya membedakan perlindungan end-to-end dari hop-by-hop dan mengusulkan kerangka evaluasi yang menghubungkan ancaman, mekanisme keamanan, cakupan E2E, dan biaya implementasi.
