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.

Landslide disaster is a geological event because the mass of rock or soil undergoes changes or movements such as falls and shifts from its original position. Meanwhile, landslides are a natural disaster that often occurs in Indonesia, this is Indonesia is an area prone to earthquakes, because Indonesia is a meeting point between three active tectonic plates, namely the Indo-Australian plate, the Eurasian plate and the Pacific plate. This research only focus to analysis rockfall types landslides, this type of landslide often occurs in rock areas, East Nusa Tenggara Province. The method used to analyze the effectiveness of rockfall type lanslide handling is to calculate the largest volume of rock that has the potential to fall by using kinematic analysis so that the handling used can function optimally. The result of analysis, it is known that in one layer of landslide plane, several alternatives can be used for different number and distance of nailing, which are calculated based on the estimated maximum load of the fallen rock, so that the use of wire mesh can be more effective.
In this study, we focus on the commerce students’ ability to correctly apply integration rules. This was in the context of online learning during the Covid-19 lockdown at a university. Students were provided with recorded lectures on integration rules and their applications. They were then given tutorial problems to work on and they could discuss their difficulties or queries with their tutors. An online quiz was designed to focus on questions which assessed their ability to apply some techniques of integration such as direct integration, 𝑢-substitution, integration by parts, area between given curves, and interpretation of word problems involving integration. We then used their responses to that online quiz to determine the performance level of the students (n = 590). The statistics based on their responses were then looked at. Based on the statistics we invited all the students to take a questionnaire. Also, we gave a written task interview to some of these students to get feedback based on the items covered in the quiz. The written task interview responses of six students were then used to obtain an insight into the online responses of participants. It was found that the majority of the students were able to adequately apply the direct integration, 𝑢-substitution techniques and area under the curve. In particular students had difficulty with integration by parts and the word problem whose modeling required the setting up of an indefinite integral.
