Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

There is a strong need for improvement of vital information on perinatal health due to high rate of anomalies such as stillbirths especially in low and middle-income countries to ensure normal and safe delivery as well as healthy baby after birth. The fetal heart rate (FHR) monitoring is an important tool for trucking the fetal health condition during pregnancy based on parameters such electrical signals, magnetic fields and acoustic vibrations which consequently enable early detection and diagnosis of fetal heart abnormalities. Various Electronic Fetal Monitoring (EFM) techniques have been used during pregnancy and delivery to ensure the fetal heart grows and functions properly. Of them, the fetal Phonocardiography (fPCG), the modern form of auscultation, is a graphical recording of fetal heart sounds (FHS) acquired from the mother’s abdomen surface. In contrast to other techniques, fPCG is safer for repetitive and long-term application which is highly recommended for high risk pregnancies. In this paper, various fPCG sensors were reviewed and compared with a purpose of developing a convenient, cost-effective, and reliable home based FHR monitoring device. The review concluded that electret microphone PUM-5250R-L model is recommended for its high sensitivity and SNR. Therefore, it will be used to develop the proposed device to acquire and measure FHS physiological parameters non-inversely
Speed Control of truck prototype using PID is one of the methods to control speed by reading the RPM value using an optocoupler sensor with weight, speed, and slope parameters. Those parameters will be processed and the error value gained from the speed is used as the input for the PID method to reduce the error value. This research is expected to be an innovation in feature implementation using speed control for heavy vehicle initiated by using a truck prototype with 1:11 scale dimension from the real truck. In fact, for testing prototypes Trucks will use lines designed according to the dimensions of the truck prototype. The result of this paper shows that the system could control the speed with up to 96,25% success rate
