Abstract

Student learning outcomes in the cognitive aspect need attention because it is the professional competence of prospective teachers related to mastery of learning materials. The purpose of this study was to analyze the effects of learning in the context of ethnoscience on learning outcomes in the cognitive aspects of prospective physics teacher students. The research method used is quantitative with two stages. First, a limited trial study with a one-group pretest-posttest design at Hamzanwadi University with a total of 9 students. Second, experimental research with a post-test only group design was conducted at the University of Mataram, with a total of 77 students. In a limited trial study, an N-gain test analysis was carried out to determine the success rate of treatment with the minimum category being in the "medium" criteria. In experimental research, the effect of treatment was tested. The research sample includes all students who take the High School Physics Studies course at the Physics Education Study Program, University of Mataram, in the 2021/2022 Academic Year. The class is divided into 3 groups consisting of a class that uses an LMS with an ethnoscience context (Group A) totaling 27 people, a class using an LMS with a module (Group B) totaling 23 people, and a class using an LMS with PowerPoint (Group C) totaling 27 people. Cognitive learning outcomes data were obtained from giving essay tests after treatment. Analysis of the data used to test the hypothesis is a one-way ANOVA with SPSS 25 calculation. The results show that the average value of Group A is 78.00, Group B is 70.70, and Group C is 70.96. Lectures in Group A have a significant influence on student cognitive learning outcomes. The conclusion of this study is that learning in the context of ethnoscience has a positive effect on the professional competence of prospective physics teachers

Abstract

Organic solar cells still suffer from relatively low conversion efficiency despite significant progress. An Ag:SiO2 core-shell nanoparticle embedded inside the active layer of an organic solar cell is expected to enhance light absorption. Light absorption within the active layer consisting of 70 nm thickness PEDOT: PSS and P3HT: PCBM was calculated using the finite element method for a variable diameter of the silver core, the thickness of the SiO2 shell, and the relative position of nanoparticle inside the active layer. The diameter of the Ag nanoparticle varies from 20 to 50 nm, the thickness of SiO2 varies from 1 to 4 nm, and the position was shifted vertically to 70 nm. The maximum light absorption in the active layer is obtained for silver nanoparticles with a diameter of 40 nm and a SiO2 thickness of 1 nm. The optimum position of the core-shell nanoparticle was found to be not at the interface between the PEDOT: PSS and P3HT: PCBM layers but a little bit shifted down into P3HT: PCBM layer. The highest increase of light absorption, compared to without Ag:SiO2, is 210%, much higher than reported in the literature. Increasing absorption is related to the excitation of surface plasmon resonance of Ag:SiO2 nanoparticles leading to the local field and scattering enhancement in the active layer of the organic solar cell

Abstract

Processing of fish products is mostly done by refining. However, spinning also has drawbacks, namely low durability and ease to rot. The purpose of the research was to test the quality of pindang fish physically, chemically, and biologically in the city of Tulungagung. The research method used is descriptive qualitative by testing the quality of pindang fish physically, chemically, and biologically. The results showed that physically pindang fish samples A and B were suitable for consumption with a value of more than 7. Chemical tests showed that samples A and B were safe for consumption when viewed from the content of salt, formalin, lead (Pb), tin (Sn), chromium (Cr), and mercury (Hg) which are all below the SNI standard. However, it should be noted that the content of water, cadmium (Cd), and arsenic (As) exceeds SNI. Biological tests showed the content of Escherichia coli, Salmonella spp. Staphylococcus aureus and Vibrio cholerae are all under the SNI, but there is one indicator, namely the Total Plate Number (ALT) which exceeds the SNI standard. Pindang fish found in the city of Tulungagung is suitable for consumption based on the results of physical, chemical, and biological tests.

Abstract

Ranggawulung urban forest is one of the remaining vegetated sites in Subang. That place needs to be managed sustainably because of its potential to be a strategic location for biodiversity. Biodiversity studies in Rangawulung urban forest need to be conducted periodically to assess and control the impact of urban development. This study was undertaken to evaluate biodiversity in Subang City, especially Ranggawulung Urban Forest as an indicator of biological management in urban areas. There were ten species of mammals found in the Ranggawulung City Forest area from six families. One of the species found, the Javanese slow loris (Nycticebus javanicus), is a protected animal in Minister of Environment and Forestry regulations (PermenLHK Number P.106/2018). The animal is categorized as CITES Appendix I and Critical according to the IUCN red list. Diversity (H'), richness (Dmg), and evenness (E') indices of the area species were 2.03, 2.06, and 0.92, respectively. Ranggawulung Urban Forest is considered important as an animal habitat in Subang City and needs to be managed properly and sustainably.

Abstract

The earthquake was one of the biggest natural disasters in Sumatra and dramatically affected this region and the surrounding area. Determination of surface deformation due to the earthquake is essential for disaster mitigation. The Global Navigation Satellite System (GNSS) is a commonly used method for determining surface deformation due to earthquakes. This study analyzes surface deformation during the preseismic, coseismic, and postseismic phases due to the 2012 Mw8.6 Indian Ocean earthquake. The study used Global Positioning System (GPS) data from the Sumatran GPS Array (SuGAr) network. The most significant horizontal deformation was observed at the LEWK station, which was 280.554 mm towards the northeast and experienced a subsidence of 40.830 mm in vertical deformation. Horizontal deformation is still felt by 22.453 mm to the northeast and vertical deformation of 8.810 mm (uplift) at stations that are farther (580 km) from the earthquake's epicenter. However, in the observation period of 60 days (postseismic phase), stations closer to the epicenter are still experiencing a postseismic phase. In contrast, stations far from the epicenter show that the postseismic phase is almost complete. In the preseismic phase, all stations experience almost the same horizontal deformation, ranging from 2.210 mm-3.639 mm, but with a different direction of movement, which may be caused by previous intense earthquake activity, which is still releasing energy (postseismic phase). On the other hand, the vertical deformation during the preseismic phase generally experiences an uplift except at the LEWK station. The results of this study can be additional information for earthquake mitigation in the Sumatra region

Abstract

This study investigates teachers' learning in technology-ethnoscience professional development for 3 months and its impact on science teachers' TPACK in East Nusa Tenggara (NTT)-Indonesia. These secondary school science teachers participate in PD that focuses on communication of information technology and ethnoscience-based materials and their applications in designing and conducting classroom instruction. Five science teacher instruments (n=28) were used, i.e. TPACK test questions, lesson plan analysis rubric, teaching observation sheets, response questionnaires and interview guides. Data is collected before, during, and after program implementation which is carried out every week. Descriptive statistics and Paired Sample T-Test were used for analysis. It was found that teachers' TPACK increased after studying in the program with significant benefits. In addition, the ability to design and implement learning changes to be more oriented towards technology-ethnoscience integration, but the benefits are not significant for all science teachers. This study suggests that teachers' PD programs in the future need to consider aspects of integrating technology in learning and the process is carried out not only when the program is run, but continues every day in class so as to create habits for science teachers. Indonesia currently needs more longitudinal PD to ensure that TPACK is integrated in science teaching and its usefulness for student learning outcomes
