In Indonesia, 651,481 people die from cardiovascular disease each year, including 331,349 from stroke, 245,343 from coronary heart disease, and 50,620 from hypertension and other cardiovascular diseases. Disturbance of changes in heart rhythm is a condition when the heart's electrical activity is irregular, it can be faster or slower than usual. This disorder is closely related to cardiovascular diseases such as hypertension, heart failure, valvular heart disease, and coronary artery disease. Changes in heart rhythm are usually not dangerous, but if the heartbeat starts to feel abnormal, it can be fatal and cause sudden death. Changes in heart rhythm can be detected using an electrocardiogram, often called an EKG. The function of the EKG is to record information about the state of the heart using electrodes attached to the body. An EKG examination usually has to be done in a hospital to find out the disease the patient is suffering from. This study implements an ECG signal real-time monitoring and processing system using AD8232 sensor module and will display the resulting ECG signal in MATLAB software. This test will be monitored using Simulink MATLAB on the MATLAB R2022b software. Testing the ECG signal studied there were two activities, namely normal activity and after exercising for five minutes. The test was carried out in a sitting position using a 21 years old woman. The results obtained from the system are made using the AD8232 sensor module has been successfully implemented using R peak detection to generate real-time heart rate. It was found that the heart rate varies between 85 to 90 beats per minute during normal activity. Meanwhile, the heart rate after five minutes of exercise reaches 107 to 111 beats per minute. From this heartbeat, we can assume that the heart is functioning normally.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79634052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional farming, which is susceptible to water shortages, pests, and other uncertainties that can lead to inconsistent and lower-quality lettuce production, hydroponic cultivation in a greenhouse ensures not only high-quality lettuce production but also continuous availability of crops, protected from extreme weather conditions such as droughts and pests. Although greenhouse cultivation is an effective approach, in lowland areas like Sekayu City, the capital of Musi Banyuasin Regency, the microclimate inside the greenhouse can be relatively high and less favorable for lettuce growth. Lettuce ideally thrives in highland regions with a temperature of around 28°C and humidity of 76%. Therefore, it is necessary to control the microclimate inside the greenhouse to optimize lettuce growth. This control requires electrical energy to operate various electronic devices in the microclimate control system, such as exhaust fans and cooling pad water pump. In this study, a solar power electrical system is designed to meet the energy needs for operating a lettuce greenhouse in Sekayu City, Musi Banyuasin Regency, South Sumatra Province. The research was conducted for 31 days, from July 1 to July 31, 2023. The highest power output was recorded on July 31, 2023, at 11 kWh, while the lowest output occurred on July 20, 2023, at 5 kWh. The research utilized an MMPT inverter, which prevents overcharging and maintains a constant 50 A input power when charging the battery. Additionally, an IoT system was used to monitor the performance of the solar power generation system, facilitating data collection on electricity production.","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86759170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At 5:00 pm the PLTS connection to the load will be disconnected and replaced with PLN. If the PLN is off due to damage or during maintenance, a generator that is operated manually will be used. Problems in the process of combining energy sources from Solar Panels to PLN require a power target of up to 10 Kva where if the power is fulfilled then the energy source from Photovoltaic (PV) will be connected to PLN and vice versa. Errors and speed in operation can be minimized by means of automation of the system operating the power supply to the load by using a PLC (Programmable Logic Controller). Optimization as a step to optimize the electricity supply in the PLTS area makes it the first source of power generation that is connected to the load, the second order is PLN if the PLTS has no power output or there is a problem and the third order is generators if PLN and PLTS have no power output. For this reason, a tool is needed that functions to move the power source alternately using a PLC (Programmable Logic Controller) as an ATS (Automatic Transfer Switch) process controller, where the tool will work automatically changing the power source if there is a disturbance that causes it to be unable to supply electricity to the user's load and also as a priority regulator of solar power sources as the main source of electricity to the load. When transferring loads from one source to another with 3 different power sources, it is faster and more effective to use an ATS (Automatic Transfer Switch) with a PLC controller compared to Manual or COS (Change Over Switch).","PeriodicalId":14205,"journal":{"name":"International Journal of Research in Vocational Studies (IJRVOCAS)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86947238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the results of the study, it is explained that there is a very significant relationship between the inlet air temperature of the compressor, the inlet fuel temperature, and the turbine exhaust temperature and active power to the efficiency of gas-fired power plants, where an increase in the inlet air temperature to the compressor will reduce the compressor efficiency, which is predicted using linear regression with an R2=0.82. An increase in the exhaust temperature and active power will significantly reduce the thermal cycle efficiency, which is predicted using linear regression with an average R2 =0.96. In addition, an increase in the fuel mass flow rate and inlet fuel temperature will increase the turbine efficiency, which is predicted using linear regression with an average R2 =0.97.

This system uses accelerometer sensor and arduino nano as a main controller and it is accompanied by Blynk application. This works for sent notification via smartphone. This tool has been successfully designed with manual testing to be able to see the sensitivity of earthquake sensor made. Accelerometer sensor works is using Tilt Method. Accelerometer sensor will tilt on surface as parable of earthquake. Accelerometer sensor will send vibration signal when earthquake occurs. Signal processing is done by Arduino nano as the main controller in system. If the signal is received by sensor then value of earthquake will be displayed on LCD screen. Status of earthquake was separated into 4 levels such as standby, alert, dangerous, dangerous and dangerous. After earthquake value appears on the LCD screen and the status is known then buzzer will sound. It indicates that the earthquake warning alarm is properly functioning. Next, NodeMCU also sends information to Blynk application, which is used as a notification and monitoring of earthquake conditions. Buzzer will sound as a warning alarm to notify peoples to save themselves. This sensor has three output coordinate points, namely X, Y, Z, which have analog values on Arduino Nano.
