Infusion is a way in which a patient can introduce fluids or drugs into the body quickly or slowly and continuously. Therefore, nurses always monitor the infusion manually and periodically to ensure the condition of the infusion fluid.&nbsp;&nbsp; The experimental method used in this study was by adding several features to make it easier for nurses to monitor patient infusions. The Infusion Monitoring System device used is based on the Internet of Things (IoT) with the Android Notification System. This research is expected to be able to monitor infusions more practically and can be monitored mobile using cellphones anywhere and anytime.&nbsp; To present this tool in this study, the author uses Nodemcu used to process data and also serves to connect to the internet. Then the sensors used are the Load cell sensor as a measuring tool for infusion volume and the Photodiode sensor as a detection tool for infusion fluid droplets. Then the calculation data from the sensor is sent to Firebase which acts as a database, and later it will be accessible and monitored via mobile phones through an android application created by the researcher. From the test results of the tools that the researcher made and the testing of comparison tools. The average of these tests gets an accuracy difference of approximately 2%.</strong> (<strong><em>Abstract</em></strong>)</p> Akbar Sujiwa, Risqi Rahmat Dianto Copyright (c) 2022 Akbar Sujiwa, Risqi Rahmat Dianto Mon, 28 Nov 2022 00:00:00 +0700 DESIGN AND CONSTRUCTION OF VERTICAL HELIX SAVONIUS WIND TURBINE FOR PUBLIC STREET LIGHTING <p>Wind power generator for lighting public roads in Tambakrejo Village, Sumbermanjing District, Malang Regency in order to minimize the level of traffic accidents. This power plant utilizes wind resources that blow to drive a wind turbine generator that will produce electrical energy. The use of wind to become electrical energy is designed from a vertical helix savonius type wind turbine as a medium for receiving wind gusts that will drive a generator to create electrical energy. The advantage of this helix savonius wind turbine can accommodate all cardinal directions because it has 2 blades that rotate 180. The role of the battery is to store electrical energy before it is distributed for public street lighting. Wind turbines or wind power plants are one of the renewable energy sources that are environmentally friendly and are starting to be widely developed at this time. In the storage and use of this electrical energy, it is very necessary to pay attention so that there is no overcharging / overcharge and excess usage / overdischarge. Therefore, the charge controller battery charging setting is used which will regulate charging or discharging. From the battery it will be connected to the Photocell for automatic control when it is dark and the light will turn on.</p> Sagita Rochman, Krishna Wijayakusuma, Rivaldo Josua Jetrin Rolos Copyright (c) 2022 Rivaldo Josua Jetrin Rolos, Sagita Rochman, Krishna Wijayakusuma Mon, 28 Nov 2022 00:00:00 +0700 AIR TEMPERATURE AND HUMIDITY DATA LOGGERS EQUIPPED WITH LABVIEW AND ARDUINO-BASED WARNING SYSTEMS <p><strong>In the industrial world the process of measuring air temperature and humidity is a very important measurement process in the production process. But in practice in the field, the process of measuring air temperature &amp;humidity is mostly done manually, which is done by recording which has the disadvantage of inaccurate measurement data. Recording temperature measurements that are done manually causes the product results to be not good, both in terms of quantity and quality. Related to these problems, the author took the initiative to create an alternative data logger device that is simpler, easier to integrate and relatively more affordable, without reducing the value of measurement accuracy. This data logger tool functions to monitor air temperature and humidity in real time, whose monitoring results are displayed through a system interface with the help of Labview software, Arduino Uno &amp; DHT sensor. The final results of the trial design of the data logger tool are able to &amp; have advantages, among others, air temperature and humidity parameters can be monitored automatically accompanied by alarm notifications, air temperature and humidity data parameters can be recorded automatically into logging data in the form of MS Excel format, and user can analyze data on air temperature and humidity parameters and the final results of the trial This air temperature &amp; humidity data logger tool has an error rate of 0.5%.</strong></p> Akhmad Solikin, Karman Copyright (c) 2022 Akhmad Solikin, Karman Mon, 28 Nov 2022 00:00:00 +0700 DESIGN & BUILD A SLURRY TRANSFER CONTROL & MONITORING SYSTEM ON THE ATM 140 SPRAY DRYER USING MICROCONTROLLER WITH ULTRASONIC SENSORS <p><em>In the current developments automation systems have begun to be applied to the industrial world, including the ceramic or tile industry. The ceramic industry in the main raw materials is soil, processing or mixing soil from crusher machines that will be produced into slurry materials ( slurry) using milling time continus (MTC), spray dryer pump machines to distribute slurries from the reservoir center to the ATM 140 reservoir. Often experiences overload slurry on atm 140 reservoirs because the system still uses swith. The operator still turns off the pump manually when there is an overload, based on these problems, an innovation is needed for an innovative slurry transfer control and monitoring tool on the ATM 140 spray dryer using an ultrasonic microcontroller-based sensor and the percentage of the contents of the reservoir that will be displayed on the LCD. </em></p> Adi Winarno, Nur Faizim, Muchammad Lukman Fauszan lukman Copyright (c) 2022 Adi Winarno, Nur Faizim, Muchammad Lukman Fauszan lukman Mon, 28 Nov 2022 00:00:00 +0700 DESIGN & BUILD OF HOME AUTOMATION TRAINER USING MCU ESP8266 NODE MODUL BASED ON INTERNET OF THINGS (IOT) <p><em>The development of knowledge and technology in the </em><em>world of education is currently advancing rapidly, providing many </em><em>new ideas, methods and innovations in the field of technology </em><em>development, especially trainers.

Coconut shells in Tarakan City are usually used for charcoal to be burned directly as an alternative fuel. This study aims to process charcoal from coconut shells into a more efficient fuel, that’s is biomass briquettes. Biomass briquettes from coconut shells are processed from charcoal making, milling, dough making, molding and drying. Coconut shell charcoal is mashed manually and combined with adhesive from tapioca flour with a ratio of coconut shell charcoal powder to tapioca flour powder is 5:1. Briquettes are printed in the form of tubes with a diameter of 4 cm and a length of 3 cm. The briquettes that have been molded are then dried in an oven at 110<sup>o</sup>C for 24 hours to remove the moisture content in the briquettes. In the study of application, it takes 10 minutes to cook 2 liters of water to a boil, which is equivalent to using a PGN gas stove with a medium flame setting, and in the process of cooking 2 liters of water it uses 602.8 grams of fuel with 390.2 grams of remaining fuel, and the efficiency is 37.14 %</p> Hadi Santoso Copyright (c) 2022 Hadi Santoso Mon, 28 Nov 2022 00:00:00 +0700 DESIGN & CONSTRUCTION OF OXYGEN SATURATION MEASURING EQUIPMENT THROUGH THE THINGSPEAK SERVER WITH MAX 30100 SENSOR <p><em>The human body requires sufficient oxygen levels for daily life, so it is important for humans to maintain oxygen levels in their bodies. Good oxygen saturation will facilitate the distribution of substances in the body, red blood cells carry oxygen from the lungs and are distributed throughout the body. It is very important for humans to keep oxygen within normal limits. Excess oxygen in the blood or hyperoxaemia: above 120 mmHg. The normal limits for oxygen levels in human blood are between: 75-100 mmHg. Lack of oxygen or hypoxaemia is less than 75 mmHg. A blood oxygen level below 60 mmHg indicates a very severe blood deficiency and you need supplemental oxygen. The design of an oxygen saturation monitoring tool through the Thingspeak server with a max 30100 sensor based on nodemcu 8266 aims to make it easier to monitor oxygen levels in the blood so that it can take early anticipation to avoid unwanted things. The design of this tool is equipped with monitoring using a Thingspeak server that can be connected to the internet or WIFI so that we can do it when we are there. This blood tool is designed using a MAX 30100 sensor as an oxygen detector which is clamped on a finger and then connected to NodeMCU 8266. After waiting for a while the sensor detects oxygen levels &lt; 80% &gt;, 100% NodeMCU 8266 sends data to the LCD and Thingspeak. On the Thingspeak server we can observe the oxygen levels in our bodies. We can use this tool far away so we don't need to go to the hospital or health center to measure the oxygen saturation in our bodies.</em></p> Winarno Fadjar Bastari, Moch.

That way the researchers made a tool that could monitor the use of electric power and can also control several load points that can be disconnected through the android application using the Internet of things. The method used is monitoring and controlling the use of electric power in the workshop so that things do not happen that are not planned I want to use the Android application using the Internet of Things that has been connected to the Arduino NoeMCU ESP8266 module. This research aims to reduce the risk that might occur due to negligence in the use of electrical loads in the workshop. Researchers hope that this tool can help stabilize electricity consumption in the workshop and avoid things that can harm the workshop itself.</p> Dwi Hastuti, Muhammad Prio Budi Santoso, Rifki Ardi Nawan Copyright (c) 2022 Dwi Hastuti, Muhammad Prio Budi Santoso, Rifki Ardi Nawan Mon, 28 Nov 2022 00:00:00 +0700
