Abstract

Within this paper, we will discuss about a development process of SpO2 monitoring system that will be used for detecting a patient in the early stage of stroke. This system will measure and compare the SpO2 from both right and left arm at the same time. Stroke patients who experience weakness in the muscles of the one hand can experience different values with hands that do not experience muscle weakness. Stroke patients who are hospitalized with an intravenous infusion in one arm can cause differences in SpO2 values between the right and left fingers. Therefore this measurement method held from that phenomenon. From the monitoring system design, the system should have two sensors to measure the blood saturation, a microcontroller to process the data, and a monitor, buzzer, and micro sd card module to store and display the data. The research shows that the system has been developed and can be used to measure patient’s SpO2 from both hands at the same time, an indicator that will rings when there is an error in the measurement, and a lcd display to show the measurement data. This system also has a microSD card writer to store the measurement data from time to time.

Abstract

A Growth in energy demand Electricity in a city will show significant economic growth. Likewise, in the Libyan city of Sirte, economic growth per year is around 6% and with a population growth rate of around 2% per year, the city is struggling to get ahead. Thus, waste generated due to economic activities of the population also increased. While all the garbage is thrown away and not utilized. Separation of types of waste contributes to the economic potential for local governments to manage organized waste. In general, 37% of waste is disposed of in landfills, 8% of which are disposed of in organic form and put into sanitary machines that produce gas. While disposal to open areas around the world includes about 31% of waste with 19% recycled through composting and 11% burned at final disposal. The last recycled process, potentially has increased of CO emission in wasted power plant. To mitigate these situations, depth analysis of the procedure collection of the wasted power plant materials is proposed. In order to reduce carbon pollutant, life cycle analysis has been usage to measure the potential reduction of CO emission in Sirte City of Libya. The performance resuls shows that by using separation materials and life cycle analysis deployment has given significant contributions that able reducing CO emission of has reduced CO Emission. By supply of 1400 tons per day, it can be seen that the electricity production generated is 3.64 MJ which is 2.6% of the production generated from the total waste burned. With the resulting heat of 9.19 MJ, it is a total heat production of 3.7%. Of the emissions produced by the material, PVC contributed the largest contribution to pollution released from the incinerator by 57.7% compared to corrugated box / board which was only 15.2% and / or injection molding by 15.2%. By amounts of 1400 tons wasted assumption, the CO2 that can be generate based on LCA analysis is 2076.87 Kg, moreover, climate change index is equivalent to 3817.58 of CO2 (Kg). Ozon depletion has shown very wonderful grade as show -164.84, meaning that the release of CFCs into the air is significantly reduced. Low carbon index has been shown based on this results, LCA could perform best good treatment for wasted classification arranged with the LCA stage.

Abstract

One of the water pollution is wastewater that comes from hospitals. The surrounding community can suffer from this disease because hospital wastewater contains quite high organic compounds also contains other chemical compounds as well as pathogenic microorganisms. stabilize the pH. The levels of pH, TDS, and TSS can also be affected by the concentration of wastewater. The higher the dilution rate of the wastewater, the lower the pH, TDS, and TSS levels will also be higher. The results of the test with 4 different water media showed that the pH, TDS and TSS sensors were able to work well where in tap water and coffee showed normal results and stale tea water and betadine water is not normal. The pH, TDS, TSS sensors are able to detect normal water conditions in tap water and coffee with a pH value of 6.89 to 5.41 TDS 179.71 to 279.41 ppm and TSS 1.00 ntu to 16.00 ntu. pH, TDS, and TSS sensors are also able to detect abnormal water conditions in stale tea water and betadine water with a pH ranging from 4.24 – 4.56 TDS 246.11 ppm – 1129 ,54 ppm and TSS 7 ntu – 13 ntu. These values ​​are in accordance with the liquid waste quality standards that have been set in the regulation of the Minister of Health of the Republic of Indonesia number 7 of 2019 concerning hospital environmental health

Abstract

The validation and accuracy of internet protocol version 6 (IPv6) performance using jumbo frames is still not perfect, due to peer-to-peer connections testing within the same operating system and between operating systems. Therefore, inaccurate data test results. To mitigated, testing with a wider platform is recommended, a medium-scale network connection is proposed such as metropolitan area networks. In this works, a connection between computer devices connected by three proxy routers are made, with different IPv6 segments on each port. Then each computer device sends traffic data to each other using a traffic-generator application. The first test through three routers without tunnel connection is carried out as the first scenario to compare performance with tunnel-based testing. Three parameters have been used in this test, such as maximum transfer unit (MTU) 1500 bytes, MTU 400 bytes and MTU 9000 bytes. The results of the tests conducted show that the use of jumbo frames using a proxy is less effective, even though it produces a larger throughput when using the MTU 4000, but there is fragmentation in the packet passing through the proxy because the packet passing through the proxy is split into 1500 byte sizes.

Abstract

Starting from the development of medical technology that is increasingly sophisticated and rapidly growing,researchers conduct medical research, namely about patient infusion handling services. In handling patient infusion, currently it is still manual which is carried out by nurses / medical personnel. Infusion handling services for patients still have shortcomings, namely the process of monitoring and replacing infusion fluids which are often late. If the problem is not treated quickly, it can lead to problems, namely the presence of air embolism in the blood vessels (the entry of foreign objects into the blood vessels, for example air). From that problem, the researchers made a new innovation in medical technology in handling infusions automatically and based on IoT. In this study, the smart online infusion device that has been made has good features and is very effective in handling infusions. This device has 3 main functions, namely: it can monitor the remaining infusion, it can change the infusion fluid automatically and it can indicate a blocked patient's infusion. This device already has a method for processing data with fuzzy logic. Media monitoring has been supported by a website that can be controlled remotely and in real time. Tests have been carried out and the effectiveness of the system is found to have an error rate of 0.2% - 0.7% and has an accuracy of 98%. Thus this tool can be used in terms of handling patient infusion automatically.

Abstract

According to the Head of the Indonesian National Police (Kapolri) General Idham Azis, the number of deaths from accidents that occurred in 2019 reached 23,530. A total of 40% of the deaths from traffic accidents are caused by human error and the influence of alcohol. The high number of deaths from traffic accidents due to the influence of alcohol is a concern for all of us. Excessive alcohol consumption is dangerous when driving because consuming alcohol will affect a person's temperament and worsen driving behavior by reducing awareness, leading to accidents. A system that is able to detect the alcohol level of a vehicle driver that can be monitored anywhere is needed, as information to alert motorists to the influence of alcohol in order to prevent traffic accidents online and on a web-based basis. Using the MQ-3 sensor for alcohol detection and the ESP8266 processor in WeMos WiFi.  The average percentage error in the measurement of the measured sample was found to have an error value of: 3.6%. Research has also succeeded in reading alcohol levels through websites.
