Abstract

Saturasi oksigen dalam darah (SpO₂) adalah indikator vital yang menunjukkan efisiensi sistem pernapasan dalam mendistribusikan oksigen ke seluruh tubuh. Pemantauan SpO₂ sangat penting dalam deteksi dini gangguan pernapasan seperti penyakit paru obstruktif kronis (PPOK), asma, dan hipoksia. Penelitian ini bertujuan untuk mengembangkan sistem pemantauan SpO₂ berbasis sensor MAX30102 yang dikendalikan oleh mikrokontroler Arduino Uno. Kalibrasi sensor dilakukan menggunakan alat pulse oximeter medis standar untuk memastikan akurasi pembacaan. Pengujian dilakukan dalam kondisi lingkungan terkendali dengan suhu 20°C hingga 27°C. Hasil kalibrasi menunjukkan bahwa sensor MAX30102 memiliki tingkat akurasi tinggi dengan deviasi rata-rata kurang dari 2% dibandingkan alat medis referensi. Pengujian terhadap beberapa subjek menunjukkan bahwa sistem mampu mendeteksi kadar SpO₂ dalam rentang normal (95%-100%) maupun rendah (85%-90%), dengan hasil yang stabil dan konsisten. Dengan hasil yang telah diperoleh, sistem pemantauan kadar oksigen dalam darah berbasis sensor MAX30102 menunjukkan potensi besar dalam mendukung pemantauan kesehatan secara efisien, akurat, dan real-time. Namun, beberapa faktor eksternal seperti pergerakan pengguna, pencahayaan lingkungan, dan suhu tubuh dapat memengaruhi hasil pengukuran. Optimalisasi lebih lanjut diperlukan untuk meningkatkan ketahanan terhadap faktor eksternal dalam berbagai kondisi. Dengan pengembangan yang berkelanjutan, teknologi ini diharapkan dapat berkontribusi dalam meningkatkan kualitas layanan kesehatan dan memberikan manfaat luas bagi masyarakat.

Abstract

Particulate matter is an air emission that is compossed of particle and liqud dropplet. This suspension is easily measured in several size distributions: ultrafine particle, fine particle, coarse particle, and total suspended particle. Coarse particle is commonly used as a parameter of air quality index. This research aims to measure coarse particle concentrations inside an air-conditioned room. The measurement was conducted using a particulate sensor and a microcontroller for an hour. All measurements were varied into: active and non active room conditions. The results show that human activities and movements in the first variation has higher concentration than the second one. The difference is about 12 µg/m3. human activities have a significant role in the submicron particulate distribution inside a room. Air-conditioned room has higher concentration than a common room.

Abstract

Chitosan is a functional material with potential for bone scaffolds due to its antibacterial properties, biocompatibility, biodegradability, low toxicity, and ability to support tissue regeneration and prevent infections in graft implantation.This study aims to identify changes in functional groups in each isolation process and identify the effect of chitosan concentration  on the activity of Straphylococcus aureus and Escherichia coli bacteria. Chitosan isolation methods are demineralization, deproteination, decolorization, and deacetylation by microwave irradiation. Analysis of chitosan functional groups using FTIR, while antibacterial activity test using diffusion method. Isolation of chitosan from pearl oyster shells (Pinctada maxima sp.) obtained a degree of deacetylation of chitosan of 95.37%. Pearl oyster shell powder identified typical peaks of calcium carbonate (CaCO₃). The demineralized powder sample had calcium carbonate (CO₃²⁻) peaks that disappeared. Furthermore, the deproteinated powder sample produced peaks with amide groups (C=O dan N-H) of reduced protein. Decolorized powder samples did not show drastic changes in the bands of the deproteinated powder spectra, but the spectra could show cleaner and clearer peaks without any interference from pigments. The last, deacetylated powder sample showed a decrease in peak intensity in the 1650 cm⁻¹ (C=O amide). The analysis of the ability of chitosan to inhibit the growth of E. Coli and S. Aureus bacteria was effective at a minimum chitosan concentration of 20%. In comparison, antibacterial activity in S. aureus is better than in E. coli. Chitosan from this shell can serve as an antibacterial, but its manufacturing techniques need optimization for better efficacy.

Abstract

Indonesia is a biodiversity country. Abundance of biological resources may encourage researchers to optimize its use. As an example papaya trees are utilized as raw material for thin films. Sap of papaya latex is doppinged with Cu. This composition is depositioned on top of FTO by spin coating method. The addition of Cu dopping aims to control the rate of crystallinity of the material. This research will add Cu between 10% and 50% solution. Based on FTIR test results, flavonoid compounds might be obtained with O-H group, some aromatic rings C = C and C = O, aliphatic compounds C-H and -CO. Flavonoid compounds are potentially utilized as dye for DSSC. The thickness of dye produced by doping Cu 10% is approximately (0.5-2) μm. Furthermore, dopping Cu from 20% to 40% can produce thickness around 10-50 nm. Meanwhile, the results of the XRD test show an effective Cu between 10% to 40%.

Abstract

QCM or quartz crystal microbalance is a non static crystal that can be used as a mass sensor. As a piezoelectric crystal, a QCM generates an electrical signal with a specific frequency. The frequency change can be utilized as a frequency counter in a mass measurement system. This study aims to develop a coarse particle sensor system using a QCM and an oscillator circuit. In line with this, this study uses an oscillator circuit and a QCM for a sensor development. Thus, the frequency measurement of the QCM contains an oscillator and a signal conditioner connected to a microcontroller. For this purpose, an Arduino Nano was used as the signal processing, while a QCM was used as a coarse particle sensor and compared to a digital dust sensor (Winsen ZH03). The sensor system was evaluated using a fixed-type crystal connected to an oscillator: 2.5 MHz - 7.2 MHz. Arduino Nano processed the frequency signal generated by the developed oscillator. The results show that the sensor system has a stable output signal compared to the comparator. There is a linear correlation between the frequency measured by the system and the oscilloscope (99.73%). It can be concluded that the sensor system can measure coarse particle concentrations from 32-620 ug/cm3 (frequencies from 2 MHz to 7.2 MHz) with a response time of 1 second. The system has an accuracy of 99% and a resolution of 1 Hz.
