<![CDATA[Dehydration is a condition where the body are lack of fluids. It is because the amount of fluid that enter in the body is less of fluid than the discharge. Dehydration is something that cannot be ignored. The high incidence of dehydration is due to the difficulty of seeing the signs and symptoms of dehydration for ordinary people. This tool is designed to handle the level of human dehydration by seeing whether the urine is normal or abnormal, whether is it mild dehydration, or severe dehydration. It can handled based on the color of the urine using a tool named Light Emitting Diode Sensor (LED) and a light dependent resistor (LDR). Tool innovation is the use of rechargeable batteries and a charger module to make it easier for users to recharge exhausted batteries. On the LCD also displays the proportion of the battery to make it easier for users to see the remaining battery weaponry. This tool is expected to be able to check the dehydration among the public in order to achieve the public health status. After the process of designing, testing, collecting and analyzing data on 15 samples and reading 20 times for each sample, the result is that the tool can work well, can measure the level of dehydration according to the human urine with an average value of 62.10. The reading results that appear on the LCD are the same or according to the level of dehydration shown on the urine color chart.]]>

<![CDATA[Liquids or medications administered through intravenous systems (infusion) is necessary when a patient requires immediate medication or requires slowly and continuously administered medications. This method is considered adequate in certain situations; however, the liquids/medications administration of through infusion has a risk when the nurse is late in replacing intravenous fluid. In this study, the system was designed to monitor the fluid infusion level by utilizing a short text message system. This system will provide information when the infusion fluid level is at 50 ml, 20 ml, and 0 via SMS. Moreover, a buzzer is utilized that acts as an alarm when the reaching 20 ml level, and infusion fluid have not been replaced yet, and when the intravenous fluid does not drip. Infra-red sensors and photodiodes are used to detect intravenous droplets of fluid, which are then used to calculate fluids' volume. The system is controlled using an Atmega 328 microcontroller. SIM Modem 900 is used to send SMS. Based on tests carried out, infusion fluid level monitoring systems have excellent performance. The percentage of system errors when detecting fluid level infuse is 1,21%. The function of sending fluid level information through SMS also works well]]>

<![CDATA[Kekeruhan air merupakan salah satu parameter yang digunakan untuk menentukan standar kualitas air. Kekeruhan air disebabkan oleh adanya bahan-bahan organik dan anorganik yang terkandung didalam air seperti lumpur dan pasir halus. Besaran kekeruhan ditentukan oleh suatu nilai yang disebut Nephelometer Turbidity Unit (NTU). Kadar maksimum yang diperbolehkan untuk air minum sebesar 5 NTU. Semakin tinggi nilai NTU maka air akan semakin keruh dan sangat berpengaruh terhadap kualitas air. Agar air yang dikonsumsi oleh masyarakat tidak keruh dan tidak mengandung bahan-bahan yang menyebabkan timbulnya bakteri maka dirancang “Portable Turbidimeter dilengkapi penyimpanan data berbasis Arduinoâ€. Alat ini dirancang dengan menggunakan sensor fotodiode yang akan menerima cahaya yang berasal dari LED serta ATmega 328 sebagai pengolah data. Berdasarkan hasil pengukuran kekeruhan yang telah dilakukan didapatkan nilai kesalahan (error) tertinggi sebesar 0.9989%.]]>

<![CDATA[Detection of veins is a critical aspect of intravenous catheterization, but it is a challenging task prone to errors, which can lead to complications such as discomfort or vessel damage. To address this issue, Vein Viewer, an auxiliary tool that employs an infrared camera, has been used to enhance vein visibility. This device captures a subcutaneous venous map using an infrared camera and then processes the images using a Raspberry Pi to display them in real-time on an LCD. This study aims to improve the use of Vein Viewer by analyzing its performance in relation to cliplimit adjustments and varying distances from the skin surface. Our findings indicate that the clearest images are obtained with cliplimits of 500 at 10 cm, 300 at 20 cm, and 400 at 30 cm. These results provide valuable insights into the optimal use of Vein Viewer and offer a practical approach to improve the accuracy of vein detection and reduce the rate of intravenous catheterization errors, ultimately enhancing patient care.]]>
