Abstract

Sistem keamanan pintu konvensional masih memiliki kelemahan, seperti kunci yang mudah hilang, mudah diduplikasi, dan tidak dapat dipantau dari jarak jauh. Penelitian ini mengembangkan sistem kontrol akses pintu berbasis Internet of Things (IoT) dengan autentikasi multi-modal menggunakan sensor sidik jari dan keypad sebagai opsi alternatif. Sistem ini juga menyediakan notifikasi real-time melalui aplikasi Telegram untuk meningkatkan kemampuan pemantauan pengguna. Perangkat dirancang menggunakan mikrokontroler ESP32, sensor fingerprint, keypad, solenoid door lock, dan integrasi Telegram Bot API. Pengujian dilakukan pada empat skenario utama: sidik jari benar, sidik jari salah, password benar, dan password salah. Setiap skenario diuji sebanyak 10 kali untuk menilai akurasi autentikasi dan stabilitas kinerja sistem. Selain itu, dilakukan pengujian pengiriman notifikasi pada setiap aktivitas akses pintu. Hasil menunjukkan bahwa baik sensor fingerprint maupun keypad mampu mengenali input yang benar dan menolak input yang salah dengan tingkat keberhasilan 100%. Pengiriman notifikasi Telegram juga bekerja tanpa kegagalan. Temuan ini menunjukkan bahwa sistem autentikasi multi-modal berbasis IoT dapat meningkatkan keamanan, keandalan, dan kemudahan pemantauan bila dibandingkan dengan sistem kunci tradisional.

Abstract

The accelerating deployment of renewable energy, particularly solar and wind power, has intensified the need for advanced energy storage systems (ESS) to address intermittency and enhance grid reliability. However, existing reviews often provide fragmented technology comparisons without a unified techno-economic framework for systematic evaluation. This paper presents a comprehensive review of studies published between 2011 and 2025, examining electrochemical, mechanical, thermal, and hydrogen-based energy storage technologies using four standardized metrics: round-trip efficiency (RTE), levelized cost of storage (LCOS), cycle life, and technology readiness level (TRL). Lithium-ion batteries (LIBs) demonstrate the highest maturity and efficiency (RTE: 90–95% and LCOS: 120–200 USD/MWh), whereas sodium-ion batteries offer promising cost reductions of 30–40% through abundant materials and scalable manufacturing. Pumped hydro and compressed air energy storage (CAES) remain suitable for large-scale applications owing to their long service life and scalability, while thermal energy storage (TES) provides cost-effective long-duration storage for concentrated solar power (CSP). Hydrogen-based storage, despite lower RTE (25–45%), offers unique advantages for seasonal energy balancing. Unlike previous reviews, this study integrates techno-economic performance with technology maturity through a TRL-oriented comparative framework, enabling systematic technology assessment based on deployment readiness, economic viability, scalability, and application suitability, thereby supporting informed decision-making and future hybrid energy storage development.
