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.

Tomato is a fruit that is consumed every day by the Indonesia population Identification of maturity of tomatoes in general is still mostly done manually by farmers. The development of information technology enables the identification of fruit maturity level based on ciitra with the help of computer. This computational way is done by using the camera as an image processor of the recorded image (image processing). The tomato fruit is identified based on the image HSV input obtained from the capture result, after obtaining the HSV for its quality detection. From several samples of grayscale data pattern of tomato fruit with different quality levels obtained by several groups of maturity level, some of the maturity level will be clarified with Learning Vector Quantization algorithm with HSV data is processed into HSV data and classified by this algorithm to get maturity level and accurate quality. This system has accuracy 76.67%
Rain attenuation is an important propagation impariments causes by troposphere which degrades the performance of Earth space communication links operating above 10 GHz frequencies. It will be the main challenge to design future Ka and V-bands satellite communication systems with high reliability. The time delay of transmission is considered as a potential technique to mitigate rain fades at these bands. To design and implement this technique requires measured real-time rain attenuation data for desired frequencies which are not obtainable at most of the places. This paper proposes a new concept of rain rate gain which can be defined as the difference of real-time rain rate with and without time delay. For the same period of time at same location, it is assumed that rain rate with time delay can represent rain attenuation with time delay by the proposed method. A model is developed to predict rain rate gain with different time delays from annual measured statistics without delay which is available at most of places. The rain rate with 1-minute integration time was measured at International Islamic University Malaysia, Kuala Lumpur campus for one year and is used to develop the model. The predicted rain rate gain was compared with rain attenuation gain using Ku-band measured data at two locations in Malaysia and found similar behavior. Hence it is recommended that rain rate with delay which is converted from annual statistics can be utilized to analyze time diversity technique at any desired frequency for rain fade mitigation
