Different students have different preferences for learning methods. Some of the might prefer visual or audio reading kinesthetic learning. It is believed that student’s methods help understand more about subject and hence contribute to their academic performance. Therefore, this study investigates whether students’ are influenced by courses they registered gender, age students. A sample 341 from backgrounds was selected in comprised Faculty Business Management, Accountancy, Graphic Design,...

Indonesia sebagai negara agraris, sebagian penduduk bermata pencaharian di bidang pertanian. Pada umumnya, masyarakat menggunakan pestisida untuk membasmi hama. Karena tingginya penggunaan maka WHO (2016) menyatakan kasus keracunan mencapai 193.000 jiwa selama tahun 2012. Untuk mengatasi permasalahan tersebut, biopestisida menjadi bahan alternatif pengganti karena lebih aman dan ramah lingkungan. Salah satu alam yang berpotensi adalah kulit durian. Rata- rata produksi durian setiap tahunnya...

High demand on batik fabric significantly increased wastewater volume from home industries. Copper, being used as mordanting agent, available in the highest concentration industrial textile wastewater. Emulsion liquid membrane (ELM) is promising selective method to recover solute. Taylor-Couette column (TCC) was proposedtoextractcopperinsteadofusingconventionalreactorthatdisturbsemulsion stability. Experiment done by varying ratio of emulsion feed phase, carrier and internal phase...

Study on the application of Taylor-Couette column for emulsion liquid membrane system has been done. To optimise extraction process under TCC, a research to investigate effect volume ratio oil water is important. Fluid viscosity was examined by varying kerosene water. TCC characterised determine flow regimes, shear stress, and energy loss distribution. Volume varied at 1:1, 1:3, 1:5, 1:6 while inner outer cylinders speed were maintained constant 31.4 0 rad/s, respectively. Investigation...

PCA and SPC were used to identify data variables that trigger flooding assess flood risk in the Muda River basin. Three (3) hydrologic variables, RL, WL, SF are analyzed using correlation tests, SPC. The Pearson test shown, WL have significant correlation. indicates all significant. shows ideal control values for runoff value exceeding UCL increases risk. Rapid expansion of development anthropogenic activities caused heavy rainfall increase above normal levels.

Due to the pandemic of COVID-19, students have started using digital technology in learning and note-taking. However, for early adopters, this method might be challenging. Thus, study objectively examines preferences students’ physical or note-taking styles. Convenience sampling among 125 Universiti Teknologi MARA (UiTM) Selangor branch, Puncak Alam Campus has been used as part methodology. Three main variables are selected assessing student’s notes based on previous which Health Expectancy,...
