Abstract

Greywater is wastewater from domestic activities sourced from kitchens, bathrooms, and laundry water. Greywater discharged directly into the environment can cause a decrease in surface water quality due to its high organic content, nutrients, pathogenic bacteria, and detergents and surfactants. One method that can be used to remove organic and nutrient content is adsorption. The success of the adsorption process is determined by several factors, such as adsorbent type, dosage, contact time, and others. One adsorbent that has attracted the attention of many researchers in recent years is magnetic biochar. This study aims to remove chemical oxygen demand (COD), total suspended solids (TSS), oil, and grease from greywater with a magnetic biochar adsorbent made from palm shells. The study was conducted by varying the dose of 1.2–8.55 g/l and the contact time of 30–150 minutes. The results showed that increasing the dose and contact time can increase the removal efficiency of COD, TSS, oil, and grease. The best results were obtained at a dose of 8.55 g/l and a contact time of 150 minutes. The removal of COD, TSS, oil, and grease was 87.91%, 88.46%, and 99.96%, respectively.

Abstract

Student learning motivation is the main aspect in achieving student success. Based on the results of observations and interviews, student learning motivation at MTsN 8 Pidie and MTsN 11 Pidie is still relatively low, which has an impact on low student learning outcomes. The aim of this research is to determine the difference in increasing student learning outcomes and motivation on respiratory system material after implementing a STEM-based learning module containing Islamic values. The population of this study were all students in class VIII MTsN 8 Pidie and MTsN 11 Pidie. The samples were taken by purposive sampling, at MTsN 8 Pidie the research samples were class VIII.1 and class VIII.2. Meanwhile at MTsN 11 Pidie the research samples were class VIII.2 and class VIII.3. Data collection uses questionnaire instruments to measure learning motivation and uses test question instruments to measure student learning outcomes. The results of data analysis using a test (Mann-Whitney test) show that there are differences in motivation and learning outcomes, namely a significant value of 0.000 < 0.05, meaning that there is a significant difference between the motivation and learning outcomes of control class and experimental class students. Therefore, it can be concluded that there is an increase in learning outcomes and student motivation by implementing STEM-based modules with Islamic values

Abstract

Scaffolding is a strategy given by teachers to guide students to successfully complete learning tasks. Teachers may provide either questioning, cueing, prompting, or explaining and is based on students’ actual ability. The purpose of this study was to investigate the effect of the scaffolding provision and students’ creative thinking skills on students' science process skills (SPS) in a project-based learning (PjBL) about acid and base concepts. A quasy factorial experiment research design was applied to collect data using a pre-validated SPS-observation. An experiment group from SMAN 3 in Jambi City had learnt the concepts using a scaffolding-assisted PjBL while a control group from the same school had learnt it using PjBL without scaffolding. Prior to the learning, creative thinking ability of the students was measured using a questionnaire. Data was then analyzed using a two-way Anova test assisted by SPSS software. The results of analyses showed that there was an effect of the scaffolding and the creative thinking ability on the students’ SPS. Potential interaction between those variables was also seen in affecting the SPS. It appears that the the presence of scaffolding and the initial students’ ability in creative thinking sinergetically improved the students’ SPS.

Abstract

Brantas River is habitat to a fish species known as the bader fish (Barbonymus altus). Research aims to evaluate the hematological profile of the bader fish as a means to assess the quality of the Brantas River in the Blitar region. Determining the waste flow from community activities that influences blood quality of bader fish is another goal of this research. To achieve this, various water quality indices were measured in the river and hematological parameters measured in the fish. Data collection was conducted once every week for three weeks during 17 January to 17 March 2022. The measurements aimed to observe any changes in the fish's hematological profile over this period. Two data analysis techniques were employed for the research: Pollution Index (IP) and Canonical Correlation Analysis (CCA). IP measurements reveal that all three stations share a common assessment, classifying them as having light pollution. When analyzing correlation measurements through CCA, it was found that erythrocytes exhibited a robust positive correlation with a pH value of 0.549, while conversely, DO (Dissolved Oxygen) showed a strong negative correlation with leukocytes with value -0.717. In summary, the water conditions in the Brantas region remain conducive for the habitat of bader fish.

Abstract

Innovation in science learning is highly recommended by various studies and education experts. Through this learning innovation, teachers create learning that facilitates students' curiosity by getting them involved in learning, which ultimately helps them understand science in depth. However, the current trend is that science classes "fail" to create innovative learning that can foster students' interest in science, so that many students do not understand science well. This research aims to determine the impact of flipped classroom learning on simple harmonic motion material assisted by computer simulations on students' conceptual understanding. A pre-experiment with a one-group pretest-posttest design was used in this research. Class X of the MIPA program was chosen as the experimental object in this research, and 30 students were used as samples. The test given is a multiple-choice test with explanations. The results showed that the average post-test score was better than the pre-test. The N-gain score is 0.79, which indicates that there is an increase in students' understanding in the high category. This shows that flipped classroom learning assisted by computer simulations can increase students' understanding of the concept of simple harmonic motion. By implementing computer simulation activities that are integrated into flipped classroom learning, learning alternatives can be enriched to help students understand science.
