Abstract

Power electronic devices are the main component of the solar power generation system. This study proposes a web-based monitoring system which presents power electronic performance parameter in a real-time across an internet connection. The investigation takes ACS712 and PZEM-004T for the power converter performance measuring and Arduino Mega 2560 with an ethernet shield for data acquisition and transmission. This paper describes the schematic design of the hardware and also explains the software work-flow and structure. The test and calibration on the sensor's voltage and current to standard digital multi-meter Tektronix DMM4050 show the sensor able to accurately read the converter performance parameter and meet the standard IEC-61724. The functionality test on the web-based information system indicates the designed user interface to present the power electronic performance parameter of the solar power generator.Keywords: Monitoring System, Power Electronics and Solar Power

Abstract

The mortality rate for pregnant women due to preeclampsia is still quite high in Indonesia in general and Bengkulu province in particular. There is no effective method to prevent preeclampsia, but early detection can help for proper treatment. Monitoring the condition of pregnancy is very important but the COVID-19 pandemic has prevented pregnant women to go to health facilities. Therefore, a pregnancy condition monitoring system was designed for early detection of preeclampsia using the android-based Certainty Factor method. The system designed consists of a blood pressure measuring device and an expert system. The device uses an MPX5500 pressure sensor, highpass Butterworth filter and an Arduino connected to an android smartphone via Bluetooth. The expert system will diagnose that pregnant women are at risk of preeclampsia or hypertension in pregnancy without the risk of preeclampsia. The blood pressure measuring  device works with an average difference to the aneroid sphygmomanometer of 7.05 mmHg with an error of 6.24% at systolic pressure and 10.15 mmHg with an error of 13.13% at diastolic pressure. The result of expert system diagnosis has an accuracy of 91.45%. So it can be said that the designed system can be used Keywords : Preeclampsia, Blood Pressure Device, Certainty Factor MethodAbstrakAngka kematian Ibu hamil (AKI) karena preeklampsia masih cukup tinggi di Indonesia umumnya dan provinsi Bengkulu khususnya. Belum ada metoda yang efektif untuk mencegah terjadinya preeklampsia, tetapi deteksi dini dapat menolong untuk penanganan dan pengobatan yang cepat dan tepat. Monitoring kondisi kehamilan sangat penting, tetapi pandemi COVID-19 menyebabkan ibu hamil tidak dianjurkan untuk ke fasilitas kesehatan. Oleh karena itu dirancang sistem monitoring kondisi kehamilan untuk deteksi dini preeklampsia menggunakan metoda Certainty Factor berbasis Android. Sistem ini terdiri dari alat ukur tekanan darah dan sistem pakar. Alat ukur tensimeter menggunakan sensor tekanan MPX5500, filter high pass butteworth dan mikrokontroller Arduino terhubung ke smartphone android melalui Bluetooth. Sistem pakar akan mendiagnosa ibu hamil beresiko preklampsia atau hipertensi dalam kehamilan tanpa resiko preklamsia. Alat ukur tekanan darah yang dirancang untuk mendukung sistem, bekerja dengan rata-rata selisih terhadap pengukuran tensimeter aneroid sebesar 7,05 mmHg dengan galat 6,24 % pada tekanan sistolik dan 10,15 mmHg dengan galat 13,13 % pada tekanan diastolik. Hasil diagnosa sistem pakar memiliki akurasi sebesar 91,45 %. Sehingga dapat dikatakan bahwa sistem yang dirancang telah dapat digunakan.Kata Kunci : Preklamsia, tensimeter, sistem pakar certainty factor
