Rancang Bangun Alat Catu Daya Pada Baby Incubator

Introduction

Rancang bangun alat catu daya pada baby incubator. Rancang bangun sistem cadangan daya otomatis inkubator bayi dengan aki, memastikan perangkat tetap berfungsi saat listrik padam. Pengalihan daya otomatis via relay. Efektif & stabil.

Abstract

Penelitian ini bertujuan untuk merancang sistem cadangan daya pada inkubator bayi agar tetap berfungsi saat terjadi pemadaman listrik dari PLN. Sistem ini memanfaatkan aki sebagai sumber tegangan alternatif yang secara otomatis akan aktif ketika pasokan listrik utama terputus. Proses peralihan daya dikendalikan oleh relay, yang berperan sebagai saklar otomatis untuk mengalihkan sumber tegangan dari power supply ke aki. Perancangan dan pengujian alat ini dilakukan di Workshop Program Studi Sistem Komputer, STIMIK Kendari, pada periode September hingga Desember 2024. Komponen utama yang digunakan meliputi aki, relay, charger otomatis, dan power supply. Power supply tidak hanya menjadi sumber utama, tetapi juga mengaktifkan relay dan mengisi daya aki. Charger otomatis akan berhenti saat aki penuh. Hasil akhir menunjukkan bahwa sistem bekerja efektif saat listrik padam. Disarankan untuk memperhatikan pemasangan kaki NO dan NC pada relay serta menambahkan sensor tegangan rendah pada charger.

Review

The article, "Rancang Bangun Alat Catu Daya Pada Baby Incubator," presents a relevant and practical solution to a critical issue in healthcare: ensuring continuous operation of baby incubators during power outages. The research successfully designs and constructs an automatic backup power system utilizing a battery as an alternative power source, controlled by a relay for seamless switching. The abstract clearly outlines the objective, the core mechanism, and the components used, demonstrating a fundamental understanding of power redundancy. The authors' initiative to address power reliability for such sensitive medical equipment is commendable, particularly given the vulnerability of grid power in many regions. The confirmed effectiveness of the system during power cuts, as stated in the abstract, highlights the immediate utility of this prototype. While the concept is sound and the initial results promising, the abstract leaves several critical technical details unaddressed that would significantly enhance the robustness and clarity of the work. Specifically, information regarding the battery capacity (e.g., Ah rating) and voltage, the power consumption of the target baby incubator, and the exact specifications of the relay, automatic charger, and power supply are absent. These details are crucial for assessing the system's operational duration, scalability, and overall suitability for a clinical environment. Furthermore, while the abstract mentions the system's effectiveness, a more detailed description of the testing methodology, including the types of tests performed, the duration of backup power demonstrated, and any load variations considered, would strengthen the claims. The authors themselves appropriately identify areas for improvement, such as the precise installation of NO/NC relay contacts and the addition of a low-voltage sensor for the charger, suggesting that these aspects were either overlooked or require further refinement in the current design. In conclusion, this research provides a valuable proof-of-concept for enhancing the reliability of baby incubators against power interruptions. To elevate this work from a prototype to a more clinically viable solution, future iterations should focus on incorporating comprehensive safety features, optimizing component selection based on detailed power requirements, and conducting rigorous, long-duration testing under simulated real-world conditions. Expanding on the suggested improvements, such as advanced battery management systems (including over-discharge and over-charge protection), would be highly beneficial. Overall, this study lays a strong foundation for developing an essential emergency power solution for critical medical devices, with significant potential for real-world impact upon further refinement and detailed technical validation.
