Abstract

This research examines the design and implementation of a Portable Pico Hydro Power Plant (PHPP) featuring a cross-flow turbine with a capacity of 300 watts. Pico hydro is a compact and efficient form of hydropower generation tailored to meet the energy requirements of remote plantation areas. The primary aim of this study is to optimize the use of low-flow water sources and low-head conditions. The research encompasses a comprehensive evaluation of several critical factors, including the assessment of water source conditions, the selection of suitable turbine and generator designs, the configuration of the system, and a thorough performance evaluation. By employing a cross-flow turbine, the Pico Hydro system is designed to convert the kinetic energy generated by flowing water into mechanical energy, which is then transformed into electrical energy. The findings of this study reveal that the portable PHPP provides a stable and sustainable energy supply for off-grid locations. This system holds considerable promise for improving energy accessibility in rural and remote regions, positioning it as a viable solution for renewable energy applications.

Abstract

Dalam bidang kesehatan, pemantauan laju pernapasan dan detak jantung secara real time yang praktis sangat penting, terutama bagi pasien yang memiliki gangguan pernapasan dan detak jantung. Penelitian ini merancang dan mengimplementasikan sensor suhu LM35 untuk pengukuran laju pernapasan dan sensor MAX30102 untuk pengukuran detak jantung, yang diolah menggunakan ESP32 dengan metode fuzzy mamdani dengan tampilan pada OLED serta hasil pengukuran bisa diakses melalui website via protokol MQTT. Klasifikasi kondisi kesehatan dibagi menjadi tiga yaitu tidak sehat, cukup sehat, dan sehat. Hasil pengujian alat ini dilakukan pada 30 sampel dan menunjukkan akurasi pembacaan yang cukup stabil, dimana akurasi pembacaan laju pernapasan 98.07% dengan perbandingan hitungan secara real, sedangkan untuk detak jantung memiliki akurasi 98.33% dengan perbandingan menggunakan oximeter. Dengan hasil ini maka alat mampu memantau kondisi tubuh secara responsif dan real time
