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.

Inflation is one of the things that plays an important role in the economy, so it needs to be considered. The cities of Surabaya and Probolinggo are located in the same province. The inflation of the two cities affects each other. This is proven by the Granger causality test. The modeling for inflation in the two cities is VAR (1). Impulse response analysis and variance decomposition were carried out as a follow-up analysis to determine the response of endogenous variables in the event of a shock. The shock to the inflation rate that occurred gave different responses to the two cities. The analysis and modeling carried out aims to enable Bank Indonesia and the local government to predict and formulate appropriate policies for the welfare of local communities.
This research investigates the influence of travel behavior on congestion and methods to reduce the problem, especially in the context of medium cities in Indonesia, where the phenomenon of congestion has common in recent years. This research is motivated by the lack of success of congestion management programs carried out by several city governments. To achieve the goal, we prepare a questionnaire and distribute it to the respondents through in-person interviews with travelers on major roads in the Greater Malang area or by Google Form. This study's main variables are education level, type of job and position, income with the variable response, congestion characteristics such as the perception of congestion, and time utilization plan if there is an improvement in road performance. The results showed that in the medium-size city's condition and the lower middle class's economic condition and the type of work as self-employed, respondents saw the congestion problem as a common problem, even generally did not consider the time lost due to congestion. It seems to answer the current phenomenon where government programs to reduce congestion problems, such as traffic management and more competitive transportation systems, are less successful. Therefore, in the future, to be more effective in handling congestion programs, the involvement of the road user's community becomes significant to do.
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.
In this paper, the effect of flexural reinforcement ratio on shear capacity of steel-fiber reinforced concrete (SFRC) beams without coarse aggregate and transverse reinforcement was investigated. Six pairs of concrete beam specimens with the size of 70 mm × 125 mm × 1100 mm and shear span to effective depth ratio of 45/10.5 were tested using two-point symmetric top loading. The flexural reinforcement ratio varies from 0.0073 to 0.0782 with 0.1 percent steel fiber ratio of the total mass. The increase in shear capacity has been proven by the test results. However, this increase turns out to be insignificant as the flexural reinforcement ratio approaches its maximum value. Transverse reinforcement is required when the flexural reinforcement ratio approaches its minimum value. Fiber reinforced concrete without coarse aggregate has lower shear capacity than that of normal concrete and closes to the lower bound value of the Joint ASCE-ACI Committee’s test results for normal concrete. The shear capacity contributed by concrete proposed by ACI, which remains unchanged for decades, is only applicable for normal concrete.
