Heart attack is still one of the leading causes of death worldwide. Much research has been done to make a portable and accurate ECG signal acquisition module as a solution to heart disease problems. This portable and easy-to-use module can be used by patients independently to find out as early as possible any disturbances in the heart's function. This ECG signal acquisition tool will generate ECG signals that will be utilized to record the patient's heart signal data. The tool consists of a biopotential circuit as a signal amplifier from the electrode sensor, then LPF filters and non-inverting amplifiers are added to eliminate noise and amplify the signal before entering a later stage. The testing was conducted on 3 subjects with 3 conditions: sitting, climbing stairs, and running. Test results showed the tool was able to display ECG signals at a fairly good PQRST interval, although noise still appeared to affect the signal. Meanwhile, Beat Per Minute (BPM) testing of each subject compared to the BPM calculation results manually resulted in a fairly low error rate of 3.52% for sitting conditions, 2.47% after climbing the stairs, and 3.73% after running.

Data from WHO 2015 shows that 70% of deaths in the world are caused by non-infection diseases, 45% are caused by heart and blood vessel disease, namely 17.7 million from 39.5 million deaths. Riset Kesehatan Dasar (Riskesdas) reported that in 2018, there were 15 of 1000 people, or 2,784,064 individuals in Indonesia suffering from heart disease. Symptoms of heart abnormalities often come suddenly. Therefore, early recognition can help to avoid heart attacks. Doctors currently use a heart sound / phonocardiogram (PCG) to assess the performance of the heart using a stethoscope. The PCG’s diagnosis is very influenced by the subjectivity of doctors because of its relatively weak and physical limitations. So that the possibility of a False Positive Result happening is quite high. To minimize this risk, a Computer Aided Diagnosis (CAD) PCG signal was developed. Several studies have proposed a PCG diagnostic method using the wavelet or Welch method and based on Neural Network are more complex. In this study, a simple diagnosis method is proposed so that the computation is easier and faster with good accuracy. The PCG signal is amplified twice, then the Fast Fourier Transform (FFT) process is carried out to obtain the characteristics of the fundamental frequency and max amplitude. The classification stage uses the Multi Layer Perceptron (MLP). From testing of 55 data PCG, the results obtained accuracy of 90%, sensitivity of 80%, PPV of 100% and NPV of 83.33%. Keywords: PCG, CAD, FFT, frekuensi fundamental, classification

Abstract Currently there are still several processes in coffee roasting that still use the traditional way of using a pan made of iron, so it took a long time to roast it and is also less efficient because of the uneven heat generated. One of the processes carried out to simplify the roasting process is by making a coffee roaster using a heater and an electric motor. This heater serves to heat the roasting room so that the heat obtained is evenly distributed throughout the roasting room. Also added is the setting in temperature and motor speed so that the taste of the coffee is more delicious. In this roasting process using the taguchi method so that data retrieval is more efficient with 9 variable experiments where the roasting temperature is 240 ℃, 250 ℃ and 260 ℃.

Small and medium industries are growing rapidly, one of which is the bottled drinking water (AMDK) industry. Therefore, there are so many studies related to the automatic filling of mineral water in both 250 ml and 600 ml glass packaging. However, this research focuses on an automatic water filling system that is controlled by a microcontroller or PLC so that it ignores the container queuing system in the form of glasses or bottles automatically, in the sense of the research the container queuing system is still done manually. The queue of glasses that are arranged in stacks becomes one of the obstacles, because the distance between the first glass and the second glass and so on is very small and can even be said to be close together. This research focuses on the mechanical system to take the glasses one by one which is arranged in a stack between glasses using acrylic material in the shape of a rectangle at a size of 100mm x 180mm. This mechanical system is to separate the bottom glass from the pile of glasses by pushing the bottom glass separator mechanically, using a pneumatic cylinder that moves horizontally. The results of the research are the process of taking 250 ml glasses one by one in a stack of glasses automatically 100% with a minimum stack of 4 glasses.

In the cultivation of swallow nests, swallow breeders experience problems, especially in maintaining the temperature and humidity of the room in the wallet bird house. Swallow breeders must be able to maintain a stable temperature and humidity and maintain the safety of the swallow from owl pests. When the temperature is hot, the swallow room will become dry so that the nest becomes damaged and the swallow feels uncomfortable living in the nest. Based on this, a control and monitoring system for swallow nest cultivation based on Android was created. This system can help reduce the temperature and humidity in the swallow nest room using a dew machine that works automatically and the swallow room door can open/close automatically using an application on a smartphone. This system can work well if given a supply voltage of AC220V and DC12V. The dew machine will work (ON) if the temperature is above 29°C or the humidity is less than 70%. The sensor read data will be sent by the NodeMCU to the blynk server and displayed on the smartphone. The swallow room door can be opened or closed based on the light intensity value measured on the LDR sensor which is then sent to the NodeMCU to drive the motor driver and stepper motor. With this system, farmers are expected to be able to monitor and control the condition of swallow’s nests using the blynk application on smartphones in real time. Key words: Swallow's nest, temperature, humidity, swallow room door, dew machine, blynk application
