Abstract

This study aimed to explore the effectiveness of technology-driven simulations in improving high school students' practical skills in mechanical measurement within the context of physics education. A quasi-experimental design was employed, involving control groups and pretest-posttest samples to assess students' understanding and application of mechanical measurement concepts. The results indicate that simulations significantly enhance students' accuracy and comprehension of mechanical measurements compared to traditional teaching methods. Notably, visual and kinesthetic learners benefit the most from using simulations prior to engaging in physical experiments. The combination of simulations and hands-on experiments was found to be more effective in developing practical skills than either approach alone. These findings underscore the value of integrating technology-driven simulations into physics curricula, particularly for enhancing learning outcomes and practical skills in mechanical measurement, with a specific advantage for learners with visual and kinesthetic preferences.

Abstract

Digital literacy is essential in educational field and digital society, but it has received less attention in schools. Objective:  This paper will analyze the effectiveness of work and energy teaching materials through guided discovery learning to improve students' digital literacy.  Method: This study applied a one-group pretest and posttest design on 26 secondary level students of grade X. Data collection techniques used digital literacy questionnaire instruments, learning outcomes tests, and interviews. Results: The results showed that the n-gain of students’ digital literacy and learning outcomes were medium criteria and high criteria, respectively. Thus, the developed physics teaching materials through guided discovery learning are effective for improving students' digital literacy. Novelty: Previous studies have not used guided discovery on work and energy teaching material to train students' digital literacy.

Abstract

This research aims to investigate the performance of activated carbon from water chestnut (WC) as an Fe adsorbent on river water samples in South Kalimantan. The WC was carbonized at a temperature of 400 °C. Then the carbon was activated with two types of activators, KOH and H2SO4 solutions. The carbonization and the activation time were also varied in two different times, 1 and 2 hours. The electrical conductivity of Martapura River water was measured to investigate its condition or quality, and yielded about 0.56   or 5600 µS/cm. It is quite large compared to the standard 1000 µS/cm. After activated carbon treatment, the electrical conductivity is reduced by about 6.67 – 13.81%. For Fe adsorption, the reduction efficiency and adsorption capacity were in the range of 7.73 % – 22.94 % and 0.50 – 1.47 mg/g. The results showed that the prepared activated carbon is effective in adsorption and decreases the Fe metal content at room temperature.

Abstract

Its crucial to get information about lead (Pb) heavy metal pollution from mining and oil palm plantation on species density in mangrove ecosystem, to anticipate its impacts. This study aimed is to compare the types and densities of vegetation in mangrove ecosystems allegedly due to mining in Setarap village, Tanah Bumbu Regency and oil palm plantations in Kuala Tambangan Village, Tanah Laut Regency. We also analysis the condition of waters (TDS, pH and DO) and organic content in sediments to acquire data from the South Kalimantan mangrove ecosystems. The results showed there were four species of true mangroves (Avicennia alba, Acanthus ebracteatus, Nypa fruticans and Rhizophora apiculate) could live well in the environment affected by mining or oil palm plantations. The species density for trees was low (933 ind/ha) for mangroves affected by coal mines, while those affected by oil palm plantations had higher densities (1,067 ind/ha). pH value of waters in affected area by coal mining showed more acidic value (pH 5.76) especially at the back, while those by palm oil plantations are more acidic (pH 6) in the estuary. Organic matter content in sediments affected by coal mines was in the range of 0.61-6.59%, while those affected by oil palm plantations showed higher values (0.12-2.19%). Lead heavy metal content (Pb) in waters affected by coal mines was 0.031-0.056 mg/L, while the area affected by oil palm plantations was of higher value (0.110-0.128 mg/L). Lead (Pb) levels in sediments indicate higher values than waters, which reach 3.512-6.046 mg/Kg (affected by coal mines), and in areas affected by oil palm plantations reaching 6.658-6.66 mg/Kg. The general conclusion is that vegetation densities in areas affected by coal mines are lower than oil palm plantations. The level of lead  (Pb) pollution in the sediments is higher than in the waters.
