Abstract

This study aims to analyze the effect of applying the mathemagic in the joyful learning method on the cognitive learning outcomes of junior high school students based on higher-order thinking skills (HOTS). The research design used a pre-experimental One-Group Pretest-Posttest with a sample of 30 students of class VII G of SMPN 1 Situbondo. The Sample was selected by purposive sampling from a population of 155 students. The research instrument was a HOTS-based test with 10 essay questions that had been validated using Pearson's product-moment correlation and tested for reliability with Cronbach's alpha. Data were analyzed using descriptive statistics and inferential statistics in the form of Pearson product-moment correlation, simple linear regression, and t-test. The results showed a very strong relationship between the mathemagic method and students' cognitive learning outcomes (R = 0.974). The relationship between the two variables is a causal relationship with a contribution of 94.8%. The t-test proves that the contribution of the influence is significant, with a t-count value = 22.707 > t-table = 1.701, and a sig.t value of 0.000 < 0.05. Thus, it is proven that the application of mathemagic in the joyful learning method has a significant effect on the cognitive learning outcomes of junior high school students based on HOTS questions Keywords: Mathemagic Method, Joyful Learning, Cognitive Learning Outcomes, HOTS

Abstract

Enzyme activity can be used as an indicator of peat decomposition in the oil palm rhizosphere of peatlands. Oil palm plantation management requires fertilization in the rhizosphere to provide nutrients for oil palm growth. The state of total nutrients in the rhizosphere can influence enzyme activity. This research aimed to study enzyme activity in relation to nutrient content in the oil palm rhizosphere of peatlands. Using the explorative method in Riau's tropical peatlands, an oil palm plantation was chosen as the main site, and a degraded forest as well as a shrubland were chosen as comparison sites. In the oil palm plantation, peat samples were taken from peat adhering to oil palm roots at depths of 0–25 and 25–50 cm and at distances of 0–1, 1–2, 2–3, and 3–4 m from the trees. In the degraded forest and shrubland, samples were taken from selected plant roots at depths of 0–25 and 25–50 cm. The triplicate peat samples were then composited for analysis of enzyme activity and total nutrient content. Results showed that enzyme activity (urease, phosphatase, β-glucosidase, and laccase) in the oil palm rhizosphere decreased as the distance from trees and the depth of the rhizosphere increased. The decline in enzyme activity was caused by low peat pH and increased water content as well as organic carbon content. Enzyme activity increased with increasing oil palm age and ash content. Total K and Zn contents showed no correlation with enzyme activities. However, total Ca and Mg contents showed a positive correlation only with β-glucosidase activity. Total Fe and Cu contents showed a significantly negative correlation with enzyme activities (urease, phosphatase, β-glucosidase, and laccase). Enzyme activity in the rhizosphere of the degraded forest and shrubland was mostly lower than in the oil palm rhizosphere.
