Abstract

Nowadays, electricity consumption in Indonesia still rising the future, as fuel cell energy reserves continue to decline, this has pushed people to switch to new and renewable energy which guarantees the availability of new electricity sources. A Photovoltaic system has been installed in the Electrical Engineering Laboratory with a capacity of 1 kWp. The PV system is proposed as a new source of electricity to support the electricity needs of laboratories other than PLN. This paper compares the modeling that has been done using the Maximum power point tracking (MPPT) algorithm namely Incremental Conductance (IC) and Perturbation & Observation (P&O) in Standard Test Condition (STC) of 1000 W/m2 and a temperature of 25ËšC. The control simulation of the MPPT DC / DC Boost Converter is calibrated to satisfy the 220V/50 Hz PLN grid. The simulation results the MPPT control with the P&O algorithm has output power of 960 W and an efficiency of 99,9 % when using the IC process has 944 W and an efficiency of 98,7%. The P&O was selected to have optimum performance relative to the IC approach in the 1000 Wp PLTS system in the Electrical Engineering Laboratory.

Abstract

Measuring the number of pulses has been used in the medical world to determine stress, relaxation, physical fitness levels, and other medical conditions. Due to the importance of checking heart rate, it is necessary to have a portable and practical heart rate measuring device so that patients with heart disease will be easier to be monitored. The device is equipped with pulse sensor to measure the heart rate in real time and provide a beats per minute (BPM). The results of normal heart rate conditions, bradycardia, and tachycardia can be monitored using mobile device application based on the measured BPM. This can be seen as output voltage generated by the pulse sensor. This pulse sensor has an average percentage error of 1.77% and deviation of 2 that is relatively small compared to standardized devices. The device is connected to the mobile application by Bluetooth which the coverage is 11 up to 45 meters depends on the obstacles.
