Abstract

The classification of the aroma pattern of pork oil and canola oil on the chemometric-based electronic nose has been classified. The electronic nose used is a series of chemical sensors combined in parallel. Sensors are made of semiconductor material that can detect changes in gas in the air. Each sample measured by an electronic nose provides output in the form of different voltages on each sensor. The data processing method used is Linear Discriminant Analysis (LDA) which is able to classify based on patterns. The samples used were canola oil, pork oil and a mixture of pork oil and canola oil with a percentage of 50%: 50%. The results of the classification of electronic nose patterns with samples of pork oil and canola oil show that each sample is fairly well clustered with the value of the first disk function is 99.9% and the second discriminant function value is 0.1%.

Abstract

The heart is an important organ of the human body. The heart functions to pump blood throughout the body. Health conditions can be seen in the condition of heart function. The heart’s function can be known through the beat when pumping blood.  The manufacture of a heart rate device has been carried out using the PPG method. This tool uses the MAX30102 sensor as input. The measurement results are displayed on the smartphone. This tool can calculate the heart rate by sticking the surface of the fingertips for ten seconds. The light waves emitted by the sensor source will hit the surface of the finger. Changes in blood volume cause changes in light intensity according to what is received by the sensor. Based on the test results, the average standard deviation of this tool's heart rate measurement is 1.176. If considered the data from the pulse oximeter is correct, then this tool has an accuracy of 98.804%.

Abstract

Telah dilakukan penelitian tentang pengaruh wadah penyimpanan air terhadap nilai DO dan TDS pada aliran sungai Metro di Kota Malang. Tujuan dari penelitian ini adalah untuk mengetahui perubahan kadar DO dan TDS pada air tercemar setelah dilakukan penyimpanan dalam waktu 24 jam pada wadah tertentu. Sampel air yang diambil berasal dari aliran sungai Metro yang berlokasi di Kota Malang dan terindikasi cemaran limbah pasar. Air diambil di empat titik yaitu titik1 berjarak 250 meter sebelum pintu pembuangan limbah pasar, titik 2 adalah titik masuknya limbah pasar, titik 3 berjarak 250 meter setelah pintu pembuangan limbah pasar dan titik 4 berjarak 500 meter setelah pintu pembuangan limbah pasar. Hasil penelitian menunjukkan bahwa kadar DO pada titik 1 memiliki nilai yang paling tinggi dan titik 2 memiliki nilai yang paling rendah. Setelah dilakukan penyimpanan selama 24 jam rata-rata kadar DO pada qirbah naik sebanyak 1,66 mg/l, pada wadah plastik rata-rata nilai DO menurun sebanyak 0,63 mg/l, pada keramik rata-rata nilai DO menurun sebanyak 0,3 mg/l. Rata-rata nilai TDS pada qirbah menurun sebanyak 4,25 mg/l, pada wadah plastik rata-rata nilai TDS naik sebanyak 0,75 mg/l dan pada wadah keramik rata-rata nilai TDS naik sebanyak 2,25 mg/l.

Abstract

An increase in the consumption of chicken meat may have an impact on the waste of chicken feathers. Several efforts have been made to treat chicken feather waste, which is difficult to decompose and can pollute the environment. Chicken feathers are biomass with a high keratin content that has the potential to be used as a carbon material. In this study, chicken feathers were used in the chemical exfoliation method to produce reduced Graphene Oxide (rGO) material. Chicken feathers are heated in two stages, at temperatures of 250 and 400 ℃ in the air. The exfoliation procedure was carried out with varying concentrations of HCl (0, 0.5, 1, 1.5, and 2 M). The X-ray diffraction spectra revealed that the sample had a rGO type carbon phase, with the crystal size decreasing as the HCl concentration increased. The presence of functional groups C-O, C=C, and C-OH identified as GO/rGO was revealed by FTIR spectra. The HCl exfoliation process reduced the sample's conductivity and capacitance, with the highest values obtained in aquadest sample (GO-0 M), about 10-5 S/m and 10-7 F/m2.

Abstract

The Prophet Muhammad whereas going to a house having a place to the companions of Ansor with a companion, he told the proprietor of the house "On the off chance that you've got water in a calfskin holder (Qirbah) put away from final night, allow it to us to drink, something else we are going drink from the water specifically ( Sahih Bukhari Muslim) From the hadith appears that there are extraordinary drinks put away in qirbah. For this reason, it is fundamental to conduct investigate on the quality of drinking water put away in qirbah made of rabbit skin. This study aims to determine the effect of water storage containers (buffalo skin qirbah, plastic and ceramic) on the physical properties of water (pH, conductivity, temperature, oxygen content and TDS) and on the growth of E Coli bacteria. The water utilized was crude well water and bubbled water which were put away in rabbit skin, plastic, and ceramic qirbah holders for three days and the information were watched each day. The information watched were pH, conductivity, temperature, oxygen substance, TDS and bacterial growth. The comes about of information examination appeared that the holder had an impact on PH, Temperature, Conductivity, TDS, Oxygen Levels and the development of E. Coli microscopic organisms in crude well water and bubbled well water. The comes about appeared that the rabbit skin qirbah was attainable and sterile as a holder for drinking water.

Abstract

Infus merupakan terapi kesehatan untuk menggantikan asupan makan atau cairan. Umumnya terapi infus diterapkan pada pasien yang menjalani rawat inap. Terapi infus memerlukan pemantauan dan pengawasan yang kontinyu oleh tenaga kesehatan. Masalah akan muncul jika dalam sebuah rumah sakit memiliki keterbatasan jumlah tenaga kesehatan sementara jumlah pasien sangat banyak. Keterlambatan penggantian infus atau macetnya tetesan infus dapat berakibat fatal bagi pasien. Untuk menghindari kejadian tersebut diperlukan teknologi tepat guna yang dapat memonitoring jumlah cairan infus. Pada penelitian ini telah dilakukan pengembangan monitoring cairan infus berbasis IoT. Sensor yang digunakan adalah sensor berat load cell yang dikonversi pada besaran volume. Alat ini memanfaatkan mikrokontroler ESP8266 yang memiliki modul wifi. Pemograman ESP8266 menggunakan Arduino IDE yang bersifat open source. Alat ini juga dilengkapi dengan LCD yang diletakkan pada tiang infus untuk menampilkan data cairan. Hasil monitoring dapat dipantau melalui smartphone melalui aplikasi telegram. Notifikasi akan masuk pada smartphone tenaga kesehatan jika level cairan infus berada pada level dibawah 50 ml. hasil pengukuran cairan infus memiliki rata-rata error 1,61 dengan error tertinggi adalah 3,5 dan error terendah adalah 0,3. Prosentase akurasi alat memiliki nilai paling rendah adalah 93%, paling tinggi adalah 99,91%, dan rata-rata prosentase akurasi adalah 98,65%.

Abstract

This research focuses on the development of hardware and software required to implement optical sensor technology. The optical sensor used is the MAX30102, equipped with infrared (IR) and red-light sources along with a receiver. The signals generated by the sensor are processed by NodeMCU and displayed on the OLED. The calibration results indicate the relationship between hemoglobin obtained using the invasive method and the output of the MAX30102 sensor, which is in the form of wavelength. It has the equation  with an  value of 0.9114. This equation is utilized to program the NodeMCU through the Arduino IDE. Validation and clinical trials have been conducted to evaluate its accuracy and applicability in clinical contexts. The results show that the non-invasive device has an average standard deviation of 0.32, indicating consistent measurement values. The non-invasive device demonstrates an average accuracy of 99.24%, signifying high precision and similarity to invasive methods. This suggests that the device holds potential as an innovative solution for Hemoglobin measurement.
