Abstract

This study aims to determine the profile of critical thinking disposition of class XII students in one of the state high schools in the City of Sukabumi. The study used a descriptive quantitative approach and a purposive sampling technique to generate 31 students of the population. Written tests applied for collecting critical thinking data.  The test consisted of 14 questions of a critical thinking disposition test with a reliability value of 0.79, a standard deviation of 10.93, and a correlation score of 0.65. There were seven indicators of critical thinking disposition include Maturity, Truth-seeking, Analysis, Systematic, Open Mind, Self-confidence, and curiosity. The results showed that the average value of students' critical thinking disposition was 27,.98% indicating that they come into a less category. There might be a need for revising to improve students' critical thinking, which they must have in this 21st century. Therefore, various models or strategies might be applied to help students build their understanding.

Abstract

Climate change is a phenomenon that discusses in one of the topics of Science (IPA) that could be integrated with biotechnology. The topic might be studied further in terms of ecopedagogy. The purpose of this study was to measure HOTS with the Higher Order Thinking Assessment instrument based on the Environmental Problem of Climate Change (HOTS-AEPCC) and to analyze the relationship between ecopedagogy and biotechnology. The method used in this research was descriptive with the data collection technique using a survey. The results indicated that the students' HOTS scores as measured by HOTS-AEPCC were still in the low category. Therefore, the results of the analysis showed that the topic of biotechnology in science learning was suitable. It assumed that ecopedagogy could combine with biotechnology. This study concludes that the students' HOTS score is still low. Therefore it is necessary to develop science learning oriented to climate change.

Abstract

Mycorrhizae are typical structures found in a plant's root system found symbiotic mutualism between fungi (myces) and roots (rhiza). Mycorrhizae have an essential role for plants because they can increase water and nutrient uptake, especially phosphorus absorption. The purpose of this study was to determine the mycorrhizal genera on the roots of parring bamboo plants (Gigantochloa atter) in Sabantang Hamlet, Toddopulia Village, Tanralili District, Maros Regency because there is no scientific information regarding this issue. This research was conducted with the wet filter method or sieving. The isolation of spores from the rhizosphere of Gigantochloa atter samples was carried out by referring to the pouring method and wet sieving using a stratified filter set. Staining techniques were used to observe the colonization of arbuscular mycorrhizal structures in the roots of the sample plants. The results showed that 27 spores were found, consisting of 15 spores of the Glomus genera, three spores of the Gigaspora genera, and nine Acaulospora genera. Observation of the root structure has not shown the presence of vesicular and arbuscular. However, only hyphae and spore structures were found because the mycorrhizal hyphae in Gigantochloa atter have not yet reached the infection stage to form arbuscular or vesicular structures
