Abstract

The objective of the study was to examine the spatial and temporal variation of the tropospheric NO2 column compared with the economic growth during the COVID-19 pandemic. Therefore, the satellite based tropospheric NO2 was acquired from the Aura Satellite during 2019-2021 over the South Sumatra region of Indonesia. The GIS analysis was conducted to produce the quarterly tropospheric NO2 map over the study area. In this study, the gross regional domestic product (GRDP) was used as a benchmark for economic growth. The GRDP would relate to the air pollution to identify possible anthropogenically induced NO2 pollution. The result indicated the GRDP growth significantly decreased when the tropospheric NO2 concentration experienced a great reduction during 2020 (Quarters III-IV). The economic growth reduced from 5.79 to -1.58 during 2019-2020. It was noted that during the decline in GRDP, the variation of tropospheric NO2 was decreased by about 33%.

Abstract

Student learning outcomes have an important role in shaping students into careful and skilled individuals. As times progress, technological advances must be balanced with students' cognitive learning outcomes to create an advanced young generation. Improving the learning model towards deficiencies in the learning model such as deficiencies in the guided discovery learning model by considering technological advances aims to maximize student learning outcomes. The aim of the research was to determine the validity of the maze chase game media developed and the differences in the use of maze chase game media development in guided discovery learning between the experimental class and the control class. The development method in this development research is divided into three stages, namely define, design, and develop, while the differentiation test uses a quasi-experimental research design using the pretest-posttest control group design method. The research location is at SMP Negeri 23 Semarang with a sample of class VII A as the experimental class and class VII B as the control class at SMP Negeri 23 Semarang for the 2022/2023 academic year. The data collection technique uses purposive sampling technique and data collection uses test and non-test instruments in the form of questionnaires. The non-test instrument is used to determine the quality of the maze chase game media which shows valid quality, very good readability and very practical practicality. In the test data, there was an increase in N-Gain in the experimental class which was higher than the control class by 0.13 in the medium category. The results of the differentiation test using the Independent Sample T Test showed that there was a significant difference between the experimental class and the control class with a tcount>ttable value of 1.98.

Abstract

The degree of soil erosion depends on the erodibility of the soil and the erosive agents. The primary energy source for soil detachment and transport in water erosion processes is rain and runoff. In the northwest region of Somalia, we thoroughly evaluated the aridity and erosivity indices. This study, aridity and erosivity indices and arid periods of Woqoyi Galbeed were assessed. In the CORINE methodology, four parameters are used to evaluate the potential and actual soil erosion risks: Soil erodibility, erosivity, topography (slope), and land cover. Fournier Precipitation Index and Bagnouls-Gaussen Drought Index were calculated using rainfall data that were measured from 2011–2019 in the region and temperature data that were taken from 50 meteorological stations. The study illustrates that most of the study area is under moderate erosion risk. Although a small portion of the Southern parts of the study areas have high erosion risk, these areas have low erosion risk due to the very steep slope. The Erosivity Index quantifies the effect of rainfall impact and also reflects the amount and rate of runoff likely to be associated with precipitation events. Evaluating the result of MFI and BGI overlaid shows that there is low erosivity risk in the northern part of the country. It includes the Bossaso, Aburin, Dararweyne, Burco, Xudun and Iskushuban weather stations. It is covering the area of 204978, 65km2, which represents 32.14% of the study area. This indicates that Northern part of the country, annual rainfall is low, whereas some areas like Erigabo and gebiley are relatively moderate in the MFI.

Abstract

This research aimed to investigate the level of scientific literacy among junior high school students. The study used a quantitative approach with a survey design. A total of 152 participants, consisting of 90 female and 62 male students, were involved in the study conducted in Bandung City and Pekanbaru City. The instruments used in the research were adapted from the Scientific Literacy Test (SLT) and an open-ended question. Data analysis involved statistical tests supported by students' responses to the open-ended questions. The findings revealed that junior high school students' average scientific literacy level was 23.46, equivalent to 57.22% of the total SLT score, categorizing it as moderate. The average scientific literacy scores for students in grade 7, 8, and 9 were 23.00, 23.78, and 23.97, respectively. Statistical tests indicated no significant difference in junior high school students' average scientific literacy score (p =0.597). The research noted lower scores on the Nature of Science (NOS) subscale (49.36%) compared to Scientific Concept Knowledge (SCK) subscale (67.30%). This highlights the need to enhance scientific literacy, particularly in NOS aspects, and suggests further investigation into factors influencing junior high school students' scientific literacy.

Abstract

Leachate is  a liquid with an unpleasant odor and dark color that generally contains high organic and inorganic matter. High levels of organic and inorganic matter in leachate will potentially cause environmental pollution if not treated properly. One of the efforts that can be made to overcome these problems is with phytoremediation techniques. This study aims to determine the effectiveness of water bamboo (Equisetum hymale) as a phytoremediation agent  of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) leachate of Jatibarang landfill. This study used experimental research with a one-factorial Complete Randomized Design (RAL) design with three treatments (P0 without water bamboo, P1 750 gr water bamboo, and P2 1000 gr water bamboo). Based on the results of research shows that water bamboo plants can reduce BOD and COD levels. The decrease in leachate BOD levels was caused by the phytoremediation process by water bamboo during the study, where the organic matter content in leachate would be degraded by microorganisms. Meanwhile, COD levels decreased due to the chemical oxidation reaction process and phytoremediation process that runs side by side. The effectiveness of reducing BOD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 28.42%; while the percentage of effectiveness of reducing COD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 39.14%
