Abstract

Peanut (Arachis hypogaea L.) is a legume crop and is one of the second highest yielding secondary crops after soybeans. Peanut production in Indonesia tends to fluctuate and is still not able to meet the needs of the community every year. To produce quality seeds, one of the ways that plant breeders do is by crossing. The cross in this study was a peanut cross between the national variety and the local Bima variety. The purpose of this study was to determine the vigor and viability of peanut sprouts from crosses between national and local varieties of Bima. This research is included in pure experimental research. The design used in this study was a completely randomized design. The data in the research that has been collected through observation and documentation methods are then analyzed using ANOVA One Way. Based on the results of the study, the data on viability parameters were obtained, namely: the highest percentage of germination was obtained by F1A seeds (Rhinoceros Variety x Local Bima) with a value of 86.66% while the lowest percentage of germination was F1C seeds (V. Kancil x Local Bima) with a value of 20%. For the parameter of germination speed, the F1 seed which had the highest seed germination speed was F1E (V. Pelanduk x Local Bima) with a value of 2.33/day while the lowest germination rate was F1C (V. Kancil x Local Bima) with a value of 0.58/day. From all research data, it was found that data from all parameters experienced significant variations or differences with P Value < 0.05 in each treatment.

Abstract

This study aims to determine the effect of using the concept attainment model on students' conceptual understanding of the material on the classification of living things. Concept attainment is a learning model that allows students to learn to think critically, gain knowledge, and solve problems using real problems. The use of this concept attainment model is intended to improve students' conceptual understanding of the material on the classification of living things. This study is a quantitative study with a quasi-experimental model using a pretest-posttest control group design. The research sample consisted of two classes, namely the experimental class using the concept attainment model and the control class using conventional learning methods. The instrument used in this study was a test, in the form of multiple choice questions to measure students' cognitive learning outcomes. Data processing was carried out with the help of the SPSS program, namely the normality test, homogeneity test, and sample t-test. The results of the hypothesis obtained on students' cognitive learning outcomes obtained a sig. 2-tailed value of 0.003, this value is smaller than the significance level of 0.05. Based on these data, it can be concluded that Ha is accepted and H0 is rejected, which means that there is an effect of using the concept attainment model on students' conceptual understanding of the material on the classification of living things.

Abstract

Microgreens are young plants harvested when they are 7–14 days old after planting (DAP) with a nutrient content 40 times higher than mature plants, especially vitamins and phytonutrients. This study aims to determine the effectiveness of various growing media on the growth of sunflower microgreens. The study used a Randomized Block Design (RBD) with one factor of growing media (M1: sandy soil, M2: charcoal husk, M3: cocopeat, M4: rockwool) and three replicates, then the sampling process on each thinwall was 10 plants. The observation data were analyzed using a one-way Analysis of Variance (ANOVA) test to determine the differences between treatments. If the ANOVA results showed significance (< 0.05), then a further Honest Significant Difference (HSD) test was conducted at a significance level of 5% to identify treatments that were significantly different. Comparisons between treatments were presented in bar graphs. The results showed that cocopeat growing media provided the best growth response with an average plant height of 13.53 cm and wet weight of 32.8 g, which was significantly superior to other media. The superiority of cocopeat is supported by its physical and chemical properties, which are able to retain moisture, provide nutrients, and support root development. Thus, cocopeat is recommended as an effective growing medium for sunflower microgreen production.

Abstract

The distribution of seagrass ecosystems along the coast of Pemenang District, North Lombok Regency, plays an important ecological and economic role. However, this ecosystem is vulnerable to damage due to human activities. The purpose of this study was to analyze the spatial distribution and extent of seagrass cover based on its cover density level. This study used remote sensing methods through the interpretation of Sentinel-2A images. The analysis process included image merging, image cropping, water column correction using the Lyzenga algorithm, image classification using supervised and unsupervised methods, and field validation at 60 observation points. The results showed that seagrass meadows were widespread along the coast and Gili islands (Gili Trawangan, Gili Meno, and Gili Air), with a total area of ​​685.26 ha. Seagrass cover density was classified into three categories, namely high (33.69%), medium (45.02%), and low (21.29%), with a mapping accuracy level of 73.33%. Based on the Decree of the Minister of Environment No. 200 of 2004, most seagrass meadows were categorized as damaged. Factors influencing this condition include domestic waste, tourism activities, ship anchors, human movement (madak), and turtle grazing activity. Seven seagrass species were identified, with Cymodocea rotundata being the most dominant. These findings emphasize the importance of regular monitoring and ongoing management to maintain the sustainability of seagrass ecosystems in the Pemenang coastal area.

Abstract

The results of observations conducted by researchers on February 2, 2025 with teachers at SMP Negeri 11 Samarinda show several problems, including the low critical thinking skills of students, learning outcomes that are not optimal, and the lack of use of digital media and innovative learning models. This condition causes students to have difficulty in understanding the learning material delivered by the teacher. This study aims to determine the influence of the Problem Based Learning (PBL) learning model based on Reading, Questioning, and Answering (RQA) on students' critical thinking skills and learning outcomes by using the Wordwall application at SMP Negeri 11 Samarinda. The research method used is a correlational method with a quantitative approach. The sampling technique was carried out by purposive sampling with classes VII-I and VII-H as research samples. Data analysis using t-test. After applying the RQA-based PBL learning model in class VII-H as an experimental class and given a critical thinking ability test and a learning outcome test, the average score of the experimental class was higher than the control class. The results of the data analysis showed that in the control class, the level of significance of critical thinking skills was 0.000 < 0.05 and learning outcomes were 0.002 < 0.05. This shows that the application of the RQA-based PBL learning model has a significant effect on improving students' critical thinking skills and learning outcomes on ecology and biodiversity materials at SMP Negeri 11 Samarinda. These findings prove that the application of the RQA-based PBL model is effective in improving students' critical thinking skills and learning outcomes.

Abstract

The background of this research is learning models that are limited in variation, which makes the students less active, especially in questioning skills. Because of that, this research has a purpose to find out the effect of implementing the Problem Based Learning (PBL) model based on Technological Pedagogical and Content Knowledge (TPACK) on students questioning skills. This research used a quantitative approach with a quasi experimental method and a non- equivalent control group design. The subjects of this research are 70 grade XI students in MAN 2 Samarinda, including class XI-B as the experimental class and class XI-A as the control class. The instruments used in this research are interviewing the teacher, observing the learning activities, and an assessment rubric of students questioning skills. The results of this research showed that students questioning skills in the experimental class increased significantly compared to the control class, as shown by the Mann-Whitney U test with a significance value of 0.015 < 0.05. The number of questions from students in the experimental class was more varied (20 questions) compared to the control class, which had fewer questions (5 questions). The conclusion is that the implementation of the TPACK based Problem Based Learning (PBL) model has a positive effect on students questioning skills in the cell material of Grade XI.

Abstract

The average biology learning outcomes of eleventh-grade students at MA Negeri 1 Samarinda are still below the Minimum Completion Criteria (KKM), while innovative learning models such as POE (Predict-Observe-Explain) have never been implemented. Biology learning has been mostly based on lectures, discussions, assignments, and practicums, while scientific attitude assessments are only taken from daily life and practicum activities. This condition requires the implementation of a model that can actively involve students to encourage scientific attitudes and science process skills (SPS). This study aims to determine the effect of the POE model on the scientific attitudes and SPS of eleventh-grade students on the sensory system material. The method used is a quasi-experimental design with a Nonequivalent Control Group Design, involving class XI-F as the experiment and XI-D as the control. The research instruments are scientific attitude questionnaires and SPS tests. The results of the analysis show significant differences between the experimental and control classes in scientific attitudes (p < 0.05) and SPS (p < 0.05 with the Mann Whitney U test). Improvements in scientific attitudes were demonstrated by an N-gain of 0.35 (moderate) in the experimental class and 0.19 (low) in the control class. Meanwhile, the N-gain of the Student-Based Learning (KPS) reached 0.60 (moderate) in the experimental class and 0.29 (low) in the control class. The conclusion of this study is that the POE model effectively improves the scientific attitudes and science process skills of eleventh-grade students at MA Negeri 1 Samarinda.
