Abstract

The COVID-19 pandemic has had a major impact on all aspects of human life, especially in the education aspect. Then, an online learning policy, as well as an online assessment, has been implemented as an effort to prevent the spread of the virus. Aspects of knowledge are assessed based on students' understanding of a concept obtained through teaching and learning activities. This study aims to develop a three-tier diagnostic test instrument that has been tested for feasibility, validity, and reliability. The method used in this research was Research and Development using a 4D model consisting of define, design, development, and disseminate stages. The research subjects were students of class VIII and IX of MTs Hidayatus Shibyan. The data collection was carried out using the observation method, validation sheets, test questions, and student response questionnaires. The validation sheet and classical theory analysis were used to determine the level of validity and reliability of a product. The results of material expert validation data obtained an average score of 24.8 out of 28 s and media experts obtained an average score of 20 out of 24 categorized in the very feasible criteria. The reliability analysis at the trial stage obtained 0.635 and the implementation test stage was 0.795 which indicates as reliable. The percentage of students' misconception profile on the material of the human digestive system at the trial stage was 33.6% then at the implementation test stage, the percentage was 41.7% categorized in moderate criteria. Students mostly responded very agree in the questionnaire with the percentage of 45.4% at the trial stage, and 54.2% at the implementation test stage.

Abstract

This study aims to analyze the characteristics, validity, readability of the E-module and the profile of students' scientific literacy after using the E-module. The design of this research is Research and Development (R&D), using the Sugiyono development model which consists of ten steps, potential and problems, data collection, product design, design validation, design revisions, product trials, product revisions, usage trials, product revisions, and mass production. The research subjects were VII grade students of SMP N 10 Magelang. The average score by the media validator is 96.25% very valid criteria and the material validator is 94.16% very valid criteria. The average score of the small-scale readability test is 91.60% and the average on the large-scale is 92.50% very good category. Based on the results of student scientific literacy profil 6.25% students are in the low scientific literacy, 13% students are in the medium category, 56.25% students are in the high category and 25% students are in the very high category . Based on the results of the study, it can be concluded that the environmental pollution E-module containing the Socio Scientific Issue is valid for use in science learning and can train students' scientific literacy skill.

Abstract

This study aims to analyze the metacognitive abilities of junior high school students through reflection blogs. This study uses the type of research One-Shot Case Study. The sampling technique in this study used a purposive sampling technique. Based on the questionnaire data, metacognitive ability was obtained with an average score of 155.5 or 78.94% in class VIII A and metacognitive ability with an average score of 153.15 or 55%. Similar to the results of the questionnaire, the data for writing reflection blogs on students showed a score of 66% in class VIII A and 63% in class VIII B. Based on these data, it was found that the metacognitive abilities of class VIII A and class VIII B students were in the high category.

Abstract

In India, green skills have been incorporated into school vocational curricula by Pandit Sunderlal Sharma Central Institute of Vocational Education, Bhopal. This study examined the perception of students of senior secondary government schools on teaching and learning of green skills in Indore, Madhya Pradesh. The senior secondary government schools where vocational courses under the National Skills Qualifications Framework have been introduced were selected for the study. Data was obtained from a sample of 80 students of class XII who had chosen vocational courses at the secondary level from four selected senior secondary government schools using a self-developed Likert type questionnaire. Mean and standard deviation of the responses were calculated to analyse the data. Students being the only respondents Friedman Test was calculated to find out the pattern of the distribution of the data. The results revealed that the distribution is the same for teaching and learning of green skills. However, there were varied responses with low mean and high standard deviation from students about their knowledge of the concept of green skills, even though the majority of students followed green practices which were being taught to them in vocational courses.

Abstract

This study was aimed at assessing both the effect (risk) and impact of a recent oil spill on heavy metal concentration in the Santa Babara River in Bayelsa State, Nigeria. Samples were collected and preserved based on standard methods. The heavy metals of interest were Mercury (Hg), Arsenic (As), Cadmium (Cd), Chromium (Cr) and Copper (Cu) due to their levels of toxicities and presence in water bodies while the five study stations were Worokuma (W), Uwanga (W), Tuweni (T), Shellikiri (S), Inarakiri (I) and Esenfakiri (E). The solar thermos elemental flame atomic absorption spectrometer (AAS), model SE-71096 made in Germany with detection limit of 0.001 mg·kg−1 was used for the heavy metal analysis. The trend of heavy metal abundance was found in this order Cr>Cu>Cd>Pb>Hg=As. All the detectable metals had risk index of greater than 5 but the highest was found in the order, Cd> Pb > Cu > Cr (149, 35, 26 and 12 respectively) which meant extremely high level of pollution. This also indicated the probability of non-carcinogenic effects occurring and increases as HI increases signifying carcinogenic risk via direct ingestion of water. Graphs were used to show trends in both mean heavy metal concentrations and risk assessment indices. Chromium and Pb had moderate contaminations for CF and CDI values, hence regular monitoring of the Santa Barbara River is of essence as most of the inhabitants take this as the only source of potable water as their wells have very high iron content.

Abstract

North Semarang District is one of the areas that is often affected by tidal floods. This study will discuss flood distribution through tidal flood susceptibility mapping and identify adaptations. The first step is to carry out flood susceptibility mapping using DEMNAS data and sea tides. The second stage is to determine the key areas based on the tidal flood susceptibility map made. Key areas are useful for identifying forms of community adaptation to tidal floods through data collection in the form of observations and interviews. The mapping results show that the flood susceptibility area reaches 582.89 Ha or around 50% of the area of North Semarang District. The key areas with high susceptibility are settlements on Jalan Tambakrejo, Tanjungmas Village and it is known that the community responds by adapting patterns to changes in physical infrastructure, economic activity, and social development.

Abstract

Weeds are a term used for disturbing plants that live with cultivated plants and if not controlled will reduce the quantity and quality of crop yields. The purpose of this study was to analyze the composition and community structure of weeds in rice aged 8 weeks. The benefits of this research are expected to provide information about the types of weeds and their characteristics. This research was conducted in Banyubiru Village, Semarang Regency; and the Unnes Biology Plant Taxonomy Laboratory. The method used in this study was random sampling using 9 plots measuring 1 m x 1 m. The results showed that there were 11 families, 17 species and 526 individuals with the highest Importance Value Index found in the species Cyperus diiformis L, namely 0.79. The weed diversity index is moderate, namely H' = 1.25.
