Abstract

Abstrak Seiring dengan peningkatan prevalensi diabetes, penelitian terhadap alat ukur gula darah non-invasif pun mulai dikembangkan, salah satunya menggunakan metode spektroskopi inframerah. Metode ini menggunakan pasangan IR LED dan fotodioda yang diletakkan segaris. Lokasi penempatannya pada bagian tubuh harus diperhatikan agar fotodioda masih mampu menangkap sinar yang dipancarkan oleh IR LED. Untuk itu dilakukan pengambilan data tegangan yang dihasilkan oleh rangkaian fotodioda pada beberapa bagian tubuh sebagai representasi kemampuan fotodioda menangkap sinar inframerah. Pada percobaan didapatkan nilai tegangan paling besar terbaca ketika sensor diletakkan pada jari yaitu pada rentang 1 volt dan tidak ada tegangan terbaca ketika sensor diletakkan pada pergelangan tangan. Hasil ini selanjutnya akan dijadikan acuan dalam menentukan lokasi peletakkan sensor pada alat pemantauan glukosa darah yang dirancang. Kata-kata kunci: diabetes, pemantauan gula darah, non-invasif, sensor inframerah Abstract In the light of the increasing prevalence of diabetes, researchs on non-invasive blood sugar measuring devices have begun to be developed, one of which utilizes infrared spectroscopy methods. This method uses a pair of IR LED and photodiode placed in line. In doing so, the location of its placement in the human body has to be considered, thereby enabling the photodiode to capture the light emitted by the IR LED. Therefore, the voltage data generated by the photodiode circuit in several parts of the body is taken as the representation of the ability of the photodiode to absorb infrared light. A higher voltage value is captured in the range of 1 Volt when the sensor is on the finger. Meanwhile, there is no voltage read on the wrist. The results of this study will be used as a reference to determine the location of the sensor placement in the designed blood glucose monitoring device. Keywords: diabetes, blood glucose monitoring, non-infasive , infrared sensor

Abstract

Solar panels are crucial components in converting sun radiation into electrical energy through the photovoltaic effect. A solar panels cannot be connected directly to the load due to its low energy conversion efficiency and low output voltage. One of the methods used to control solar cells to operate efficiently at their maximum power point is MPPT. In this paper, we design a DC-DC converter by modifications of the Butterworth filter circuit and feedback circuit in the MPPT system for storing solar panel electrical using the Hill Climbing (HC) method. The device consists of a DC-DC buck converter circuit, two pieces of INA219 sensors, a DS18B20 temperature sensor, a MAX44009 light intensity sensor, a SD card module and a DS3231 RTC. The DC-DC buck converter circuit simulation is carried out to determine the optimal load. The load optimization was conducted by analyzing the AC simulation using Ltspice software. The magnitude of the output voltage ripple in nine different loads was observed. From the simulations performed, it was found that the 50 Ω load has an output voltage ripple of 8.96 mV and is smaller than the other loads. The main DC-DC buck converter circuit is designed using a butterworth low pass filter with a cut-off frequency of 1000 Hz (R = 50 Ω, L = 33.8 mH and C = 750 nF) and a feedback circuit with a cut-off frequency of 500 Hz is added. From the prototype measurement, it was found that the average output power was 3249,7 milliwatts and the average input power was 4779 milliwatts, thus the average efficiency was 68%. With these results, the DC-DC converter circuit configuration is suitable for use in electrical energy storage systems from solar panels that have high efficiency.

Abstract

Transportation and industrial activities have contributed to an increase in the concentration of pollutant gases such as CO, NO2, and SO2 in the air. High concentrations of these gases can adversely affect human health. One approach to addressing this issue is by measuring and monitoring gas concentrations in the air. The advancement of technology, specifically the Internet of Things (IoT), facilitates the monitoring process. Therefore, this research focuses on the development of a gas concentration measurement system, utilizing the MQ-7 sensor for CO, the MiCS-6814 sensor for NO2, and the MQ-136 sensor for SO2. Additionally, the system is integrated with a website as a platform for monitoring the sensor measurements. The research results indicate that the system has been successfully developed with relative errors of 0.286% for the MQ-7 sensor, 0.325% for the MiCS-6814 sensor, and 0.280% for the MQ-136 sensor. The system underwent testing at three different locations, conducting gas concentration measurements in the environment for 24 hours. The environmental testing revealed measured gas concentration ranges of 2.52-7.67 PPM for CO, 0.00450-0.103 PPM for NO2, and 0.0100-0.0652 PPM for SO2. The measurement data is accessible and observed in real-time through the website, presented in graphical form, indicating average concentration values of CO, NO2, and SO2 over a 3-hour period. Moreover, the website is equipped with indicator lights that serve as alarms if the environmental gas concentration exceeds predefined thresholds.
