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.

The Fall armyworm (FAW), Spodoptera frugiperda J.E Smith is an invasive pest that is now an important pest of maize crops in Indonesia and Bali in particular. This study aims to 1) determine the invasion process, 2) population development, and 3) the level of FAW pest attack on sweet corn and glutinous corn varieties in the Gianyar Regency, Bali. This study used a pair of plot design between plant varieties. A sampling of plants was carried out systematically randomly with a "U" shape. Furthermore, the sample plants were observed at intervals of one week. The results showed that the FAW invasion process had started since the plants were 1 week after planting (wap). Female moths prefer glutinous corn more strongly than sweet corn for the egg-laying process. The highest larval density was found at the age of 4 (wap) plants, respectively 30.6 larvae in glutinous corn and 26.0 larvae in sweet corn. The population development of FAW showed the same pattern in the two varieties of maize, namely the peak spawning occurred at the age of 2 (wap), while the peak population of larvae instar-1, -2, -3, -4, -5, and instar-6 respectively occurred at 2, 3, 4, 5, 6, and 7 (wap) respectively. The attack intensity of FAW showed the same tendency as the population density, which was heavier in glutinous corn, reaching 34.74% compared to sweet corn, which was 33.72%.
Renewable energy comes with a great deal of hope for a better planet with low CO2 emissions and unlimited sources. One of these promising sources of energy is the one that comes from the sun. Solar energy harvesting can be combined with the ever famous IoT monitoring. The current internet connection and speed can meet the need for an online and up-to-date view of the performance of the PV system. This paper compares data from IoT monitoring and direct measurement of PV panels. The experiment was conducted by installing two panels with different means of output and efficiency monitoring. The difference in output between IoT-based monitoring and direct measurement is 2.9708 watt, and the efficiency difference is 3.085%. While the measurement is different, the graphic profiles are the same, indicating that the IoT monitoring and direct measurement can display the same data with the appropriate calibration and light sensor.
