Abstract

Sebagai bentuk kepedulian terhadap pencegahan penyebaran virus COVID-19, dibuat alat pengukur kesehatan yang akan diaplikasikan di puskesmas. Alat yang dibuat dapat mengukur temperatur tubuh, detak jantung, dan kadar oksigen dalam darah menggunakan teknik photoplethysmography. Alat ini juga berfungsi untuk menghubungi petugas puskesmas bila kondisi kesehatan pasien menurun menggunakan sistem short messaging services (SMS). Mikrokontroller Arduino Mega 2560 digunakan sebagai penerima data dan kendali sistem. Sensor yang digunakan adalah sensor temperatur MLX90614 dan sensor kadar oksigen MAX30102. Sistem pengiriman SMS menggunakan board SIM808. Alat ini beroperasi menggunakan sumber listrik AC, dengan baterai Li-ion sebagai cadangan catu daya. Pengujian alat dilakukan di pintu masuk Laboratorium Teknik Elektro Universitas Multimedia Nusantara. Setiap mahasiswa yang datang ke laboratorium tersebut wajib melakukan cek kesehatan menggunakan alat tersebut. Selama masa pengujian, alat dapat mendeteksi temperatur dan kadar oksigen mahasiswa dengan tepat, serta alat mampu bertahan selama satu hari penuh hanya dengan menggunakan baterai. Alat ini akan diletakkan dan diaplikasikan di Puskesmas Kelapa Dua Tangerang.

Abstract

The wireless power transfer (WPT) system has become popular given its safety and flexibility in electric vehicle (EVs) charging applications. Due to the increasing number of EVs, vehicle to grid (V2G) can be implemented in the future in which a bidirectional WPT is one of the key features. A high-efficiency bidirectional resonant WPT system is studied and implemented in this study. Besides bidirectional capability, single stage and regulated output voltage are other features of this work. It is done by using the variable frequency control without sacrificing efficiency and conforming to the typical frequency range of the WPT system for EVs application. The analysis of the series-series compensated WPT is presented, followed by the design consideration of the developed bidirectional WPT system. At last, the implementation and experimental results for a 3 kW laboratory prototype are also presented to show the validity and the feasibility of the proposed scheme. A 96.8% efficiency at a 210-mm gap and a 95% efficiency at a 250-mm gap can be achieved under a rated power condition.
