Physical exercise is an activity carried out to maintain a healthy body condition. Health is the most important part of all activities carried out by humans by paying attention to vital signs such as body temperature, heart rate, and others on a regular basis. Regular physical exercise for a long time, which is about 30 minutes, can cause changes in bodily functions. The acute effect of excessive physical exercise results in an increase in heart rate and body temperature. This study is designed to control and monitor body temperature as well as other vital signs of health during exercise, and to avoid excessive physical exercise. Research that has been conducted previously obtained the results of values before exercise for body temperature using infrared and ds18b20 which have a range between 34.550C - 36.090C and 35.060C - 36.190C, values for skin moisture range from 47% and heart rates between 94 Bpm - 118 Bpm. Meanwhile, during the exercise, the body temperature is between 36.380C - 36.810C, skin moisture between 47% - 15%, and a heart rate between 105 Bpm - 95 Bpm with a value of delay between 0.034897000s - 0.037563000 s during the live streaming. Based on this research, it can be concluded that the fan can turn on automatically and successfully reduce the user's body temperature gradually with a temperature range between 35,000C - 36.80C.

The use of digital filters is needed by electronic systems, such as in signal and audio processing. The use of digital filters is to filter frequencies and modify the frequency spectrum of a signal so that the desired goal is obtained. The purpose of the filter is a series that passes a certain desired frequency band and dampens other frequency bands. The method used in designing the FIR filter is using the windowing method. There are several techniques included in the windowing method, namely rectangular, hamming, hanning, and kaiser. For the windowing work system it really depends on the type of window used, therefore there is a comparison between the four. This research will be developed by designing a digital FIR filter that is implemented on the raspberry pi device which is expected to be well integrated using the simulink matlab. So a study was made that raised the problem of how to process digital signals to apply the FIR filter using the windowing method that was simulated using the matlab program and implemented on raspberry pi. From the test results, it can be seen that the Raspberry pi can be integrated well using the Simulink matlab. The bigger the ripple, the stopband attenuation, and the bandwidth width on the result of the signal output frequency response affect the resulting order, that is, the smaller it is.

Industrial accidents are accidents that occur in the workplace, especially in an industrial environment. The most important factors in the occurrence of work accidents are technical equipment, work environment, and the workers themselves. Lighting that is not enough to illuminate workers when using machines can cause work accidents during the production process. In addition, hot conditions can also cause work accidents because hot temperatures make the body uncomfortable at work, reduce agility, interfere with the carefulness of the brain, and ease emotions so that workers cannot concentrate and can cause work accidents. The purpose of this research is to create a system that can detect temperature, smoke, and light in a GSM-based industrial environment. This system can help prevent industrial accidents by obtaining information about industrial environmental conditions for workers in the form of SMS. Temperature, smoke, and light sensors will send SMS information when each sensor exceeds the threshold value specified in the program. Information delivery is carried out using 3 different providers, namely Three, Indosat, and Telkomsel by comparing the amount of delay. The test results can be concluded that the three sensors can work well. The temperature sensor can detect temperature with an average error value of 0.03%. The smoke sensor can detect smoke with an average value of 0%. Provider Three can send information with a small average delay, namely 1.46s. Indosat providers can send information with an average delay of 3.68s. Telkomsel providers can send information with an average delay of 1.52s.

The rapid advancement of science and technology encourages dynamic transformation in various sectors, especially in the field of information and communication technology (ICT), especially with the existence of Android-based smartphones. This advancement revolutionizes the way we access information, especially about various processed fish dishes in Indonesia. However, despite the plethora of culinary offerings, travelers often find it difficult to discover traditional dishes through social media platforms. To bridge this gap, a new app that utilizes artificial neural networks has been developed. The app allows users to photograph and upload images of processed fish dishes to recognize and provide detailed descriptions and recipes. In addition, integrating Google Maps makes it easy for users to find nearby places that serve these dishes. Testing the app with a dataset consisting of 1577 images of six types of processed fish dishes yielded promising results, with accuracy reaching 97.57% over 120 epochs. This innovation not only preserves cultural heritage but also enhances the culinary experience for locals and tourists.
