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.

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.

The condenser is a device for condensing steam from a turbine. Used steam from the turbine enters from the top of the condenser, then experiences condensation due to absorption of heat by injected cooling water. Condenser is one component that is very important in electricity generation. Lahendong Geothermal Power Plant has produced 4 × 20 MW of electricity. Condenser performance will affect the efficiency of a power plant and affecting the condenser is the heat transfer rate and the mass flow rate of the water in the condenser. this research is a correlation study between cooling towers and condensers, because one of the parameters used is condenser cooling water distributed by cooling towers. The calculation results show the highest heat transfer rate reaches 1327.53 Watt at water temperature 3.16 ℃ with the value of water mass flow rate 76.97 kg / s, while the lowest heat transfer rate value reaches 579.58 Watt at water temperature 1.38 ℃ with the value of water mass flow rate 40.09 kg / s. This means that the temperature of the cooling water is directly proportional to the heat transfer rate and the water flow rate of the condenser.
