Abstract

To find out or predict the potential of a particular stand or community is to take measurements. Measurement is used as the main determining factor that influences the accuracy of the data obtained. Measuring tree height is an important variable in providing a quantitative description of trees and stands that can determine the quality of stand locations and estimate several parameters. Likewise with tree canopies, the canopy or crown of a tree is a condition where the branches and leaves of a tree form overlapping each other. The aim of this research is to determine the height and canopy cover of several tree samples taken from the research location, namely Science Park, Duren Sawit District, East Jakarta City. The method used to collect tree height data is by using an inclinometer, and to measure tree canopy cover, it is measured using the GLAMA application. The results of this research showed that the Pinus merkusii tree was the tree with the highest height, namely 25.7 meters and the Leucaena leucocephala tree was the shortest tree, namely 2.4 meters. The tree height results were obtained based on tree height measurements carried out using trigonometry principles. Meanwhile, the largest Canopy Cover Index percentage was found in the Leucaena leucocephala tree, namely 77.48% and the smallest Canopy Cover Index was found in the Mangifera indica tree, which was 56.22%, with the largest and smallest percentages having a difference of 21.26%.. This difference was obtained through processing data obtained through the GLAMA application.

Abstract

The escalating environmental issues in Indonesia highlight the need for early environmental education to cultivate environmental literacy, defined as a crucial attitude of environmental awareness, among students. An effective approach to cultivating environmental awareness through education is the Self-Directed Learning (SDL) model integrated with peer teaching, as this combined independent and collaborative method enhances students' sensitivity and independence in environmental problem-solving. This research aims to analyze the effect of implementing the SDL (Self-Directed Learning) model integrated with the peer teaching method on students' environmental literacy levels in the topic of environmental change. The research method employs a quantitative approach with a quasi-experimental design. The research sample consists of 36 students obtained through simple random sampling. The results of hypothesis testing indicate that the integration of SDL and peer teaching significantly contributes to improving students' environmental literacy. These findings imply that collaborative and independent approaches in learning can enhance students' understanding of environmental issues more effectively. Therefore, it can be concluded that the integrated SDL and peer teaching model can be applied to the topic of environmental change to foster students' environmental literacy. This study provides a foundation for future research to further develop the Self-Directed Learning (SDL) model integrated with peer teaching, exploring its application with diverse media and teaching materials across various subjects.

Abstract

This research focuses on the exploration of moss in the Bogor urban habitat, to explore the identification of moss types, measuring the level of diversity, and assessing the level of uniformity in the context of the urban environment. Data collection at the research location was divided into 3 stations with different environmental parameters. The method used in this research was an exploratory survey using the belt transect technique. The sampling method is purposive sampling with the help of a quadratic plot. The results of this research found 20 moss species identified on the green belt of Jalan Pajajaran, Bogor with a diversity index for the three stations respectively, namely 2.45; 2.02; and 1.78 which is classified into the medium category, and the uniformity index for the three stations respectively is 0.835; 0.814; 0.811 which is classified as high. These results show that the moss found can live by adapting to environmental factors in urban areas such as fluctuating temperature, humidity, and light intensity.
