Abstract

The existence of trees is very beneficial for humans’ life. There are utilizations of tree such as urban planning and reforestation. However, the tree can be dangerous when the tree is aged and decay because of several factors that might be cause fallen tree. Furthermore, the monitoring activity is needed to know the condition of the tree. One of the methods that can be used to detect hollow in living tree is Electrical Resistivity Tomography (ERT). The ERT is an efficient and nondestructive method that can be potential to estimate resistivity cross section. The measurement of ERT conducted on Swietenia mahagoni and Gmelina with unhealthy and healthy condition visually. The data processed using Res2Dinv and reconstructed for obtaining 2D resistivity cross section. The results shows that the unhealthy Swietenia mahagoni has logarithmic resistivity value range between 0.1-1 Ωm and the healthy Swietenia mahagoni has 1-4 Ωm. Meanwhile, the unhealthy and healthy Gmelina has logarithmic resistivity value range between 0.5-4.5 Ωm and 0.5-3 Ωm, respectively. It is shows that the tree indicated health visually from biological view does not mean the tree is decay. It might be influenced by phenology factor and/or the species of the tree.

Abstract

One of the problems that are often found in universities, especially in physics subjects, is the existence of misconceptions in students (learners). This study aims to determine the effectiveness of using the multiple-representation approach Based on E-Module in reducing the misconceptions of prospective physics teachers during the Covid-19 pandemic. The method used is quantitative research with a one-group pretest-posttest design. The sample consisted of 25 prospective physics teachers at one of the universities in the city of Mataram. The instrument used in this research is an open-ended three-tier test. A total of 10 test items with 30 questions were used in this study. The test was given twice, namely before and after treatment. The test results data were then analyzed using descriptive statistics to determine the decrease in the percentage of students who experienced misconceptions. Based on the results of data analysis shows that there is a decrease in the percentage of students who experience misconceptions by 31.89% from the initial number of 57.19 to 25.30%. This decrease in misconceptions was also followed by an increase in the percentage of students who understood the concept from 18.14 to 72.38%. Thus, it can be concluded that the application of the multiple representation approach assisted by E-Modules can be used as an alternative to reduce misconceptions and improve understanding of the concept of prospective physics teachers in the COVID-19 pandemic

Abstract

The fate of glyphosate in soil and water is dependent on the properties of glyphosate and its envoronement. Behaviour of glyphosate in soil, sediment and water is strongly influenced the way by which it can be adsorbed by soils, sediments, and suspended material in water. The role of soil organic matter, clay mineral, and amorphous minerals on the adsorption of glyphosate depends primarily on the nature and properties of the soil itself and the properties of glyphosate. Environmental factors have some influence on sorption and degradation of glyphosate. Glyphosate is rapidly inactivated in soil, is in part due to adsorption. Some soil properties have been identified strongly influence adsorption of glyphosate, such as clay minerals, composition of cations in exchangeable site of clay and organic matter, unoccupied phosphate adsorption site, degree of humification, and soil pH. Adsorption limits the availability of glyposate for microbial degradation. The sorbed glyphosate is not directly available to microorganisms in soil. Evidence also suggests that not only a strongly sorbed compound such as paraquat but also weakly sorbed compounds such as flumetsulam and picloram can persist for long periods when they are sorbed by soil constituents. This suggests that the interaction between sorption and biodegradation should be considered in predicting the fate of pesticides in soils and sediments.

Abstract

This study aims to analyze the problematic analysis of science learning based on local wisdom and the solution in terms of its solution in terms of several aspects, namely: curriculum, teachers, students, learning strategies, assessments, facilities and infrastructure. This type of research is descriptive qualitative. The research data was obtained through literature review and giving questionnaires to 65 respondents. The respondents came from 201 teachers who are alumni at one of the universities in Mataram City who are members of WAG IKA (WhatsApp Group Alumni Association). The questionnaire contains a list of six open-ended questions. The results of the study provide information that curriculum changes are expected to answer the needs of the times and consider local wisdom according to the characteristics of each region, these changes require mental changes from curriculum implementers. The quantity of teachers is sufficient but the quality of teachers still needs to be improved, especially in designing learning tools based on local wisdom. From the student factor, the role of parents as well as motivation and interest in learning is important to improve so that learning outcomes are as expected, and students also care about local wisdom in their neighborhood. For this reason, teachers need good learning strategies in planning local wisdom-based learning processes in the classroom by considering authentic assessments that are able to measure aspects of students' attitudes, knowledge, and skills in learning science. Facilities and infrastructure that can support science learning activities based on local wisdom include: library facilities, science laboratories, multimedia laboratories, and objects of local wisdom around students.
