The process of sending information there is always interference or noise, the nature of noise cannot be eliminated but can be minimized. In this study, the author uses an IIR Digital Filter because the IIR filter has an impulse of infinite duration so that it can be matched with an analog filter which also has an impulse response of infinite duration. 1 and chebyshev type 2 on MATLAB. MATLAB code is used to create a filter design program according to the specifications that have been made. MATLAB Simulink is used to create a block filter design to be implemented on the Raspberry Pi. Raspberry pi is used as a device to process the filter. The results of running MATLAB code and also Simulink are compared to see if the implementation results are the same as the program results. The types of filters that are good for use in IIR digital filters are Butterworth filters and Chebyshev 2 filters because there is no ripple in the passband. The type of filter that is not good for use in digital IIR filters is the Chebyshev 1 filter. The effect of ripple changes on the order value is that the smaller the ripple value, the larger the resulting order value. The effect of changing the stopband attenuation is that the more the stopband attenuation, the smaller the resulting order.

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.

Communication plays an important role in society. This can be seen in the amount of information that is spread, such as information in the form of sound, images, and videos. But communicating is not always easy. Due to the large number of sounds emitted from different sources, other sounds will be disturbed. The interference caused by noise can distort the information signal, leading a sine wave to integrate a minor noise signal. As a result, the receiver cannot differentiate the actual information signal and the added noise. This study proposed a noise-reduction system by analyzing the effect of the number of filter orders on the noise canceler system. The information signal will be processed using the STM32F4 noise canceller system, which will then be filtered using an adaptive filter with a Finite Impulse Response (FIR) structure and the Least Mean Square (LMS) algorithm. The test results show that the best SNR value is obtained at Order 40 of 5.3671 dB at a sound duration of 14 seconds, while the best PSNR value is obtained at Order 40 of 21.3557 at a sound duration of 9 seconds, and the higher the filter order value, the smaller the MSE value.
