Purpose – Students’ incompetence to deal with the intricacies of technology during the teaching and learning process may have negatively affected their online learning process particularly throughout the COVID-19 pandemic. It is critical to research technostress influence on online learning behaviours among undergraduates. Thus, this research intends to examine the predicting factors that contribute to technostress and the correlation between undergraduates’ technostress and the behavioural intention to use online learning. Methodology – This study employed an online survey and cross-sectional data towards 212 respondents, all of whom were Diploma students from Universiti Teknologi MARA (UiTM) Pahang. This study added three new variables to the existing Unified Theory of Acceptance and Use of Technology (UTAUT) namely teaching-related aspects, price value, and technostress. Structural equation modelling (SEM) was performed to analyse the measurement model and evaluate the developed hypotheses. Findings – The findings established a significant correlation between technostress and behavioural intention to use online learning. Facilitating conditions also demonstrate a significant relationship to technostress. Significance - The study’s findings are likely to increase researchers’ understanding of the present condition of technostress in higher education as a consequence of the implementation of online learning regulations, as well as the scale of the impacts on higher education.
The purpose of this study is to investigate the effectiveness of banana trunk as an adsorbent in removal of heavy metals in aqueous solution. Functional groups of adsorbent were determined using Fourier Transform Infrared spectroscopy (FTIR). Batch experiments were conducted to determine the adsorption percentage of heavy metals (Cu, As, Pb and Zn). The optimum adsorption using banana trunk was based on pH difference, contact time and dosage. Adsorption percentage was found to be proportional to pH, contact time and dosage. Maximum adsorption percentage of Cu, As, Pb and Zn at pH 6, 100 minutes and 8 gram of dosage are 95.80 %, 75.40 %, 99.36 % and 97.24 %, respectively. Langmuir and Freundlich isotherms were used to determine the equilibrium state for heavy metals ion adsorption experiments. All equilibrium heavy metals were well explained by the Freundlich isotherm model with R 2 = 0.9441, R 2 = 0.8671, R 2 = 0.9489 and R 2 = 0.9375 for Cu, As, Pb and Zn respectively. It is concluded that banana trunk has considerable potential for the removal of heavy metals from aqueous solution.Keywords: adsorption, heavy metals, banana trunk, pH, contact time Abstrak Kajian ini bertujuan untuk menyiasat keberkesanan batang pisang sebagai penjerap dalam penyingkiran logam berat di dalam larutan akueus. Kumpulan berfungsi penjerap ditentukan menggunakan Spektrospkopi Infra Merah Transformasi Fourier (FTIR). Eksperimen kelompok dilakukan untuk menentukan peratusan penjerapan logam berat (Cu, As, Pb dan Zn). Penjerapan optimum menggunakan batang pisang berdasarkan pH yang berbeza, masa sentuhan dan dos penjerap dianalisis dalam eksperimen kelompok. Peratus penjerapan didapati berkadar terus dengan pH, masa sentuhan dan dos penjerap. Peratus penjerapan maksimum Cu, As, Pb dan Zn pada pH 6, 10 minit masa sentuhan dan 8 gram dos penjerap masing-masing ialah 95.80 %, 75.40 %, 99.36 % dan 97.24 %. Isoterma Langmuir dan Freundlich telah digunakan untuk menentukan keadaan keseimbangan bagi eksperimen penjerapan logam berat. Semua keseimbangan logam berat dijelaskan dengan baik oleh model isoterma Freundlich dengan R 2 = 0.9441 , R 2 = 0.8671 , R 2 = 0.9489 dan R 2 = 0.9375 masing -masing untuk logam Cu, As, Pb dan Zn. Dapat disimpulkan bahawa batang pisang mempunyai potensi besar untuk penyingkiran logam berat daripada larutan akues.Kata kunci: penjerapan, logam berat, batang pisang, pH, masa sentuhan
