Abstract

Research was conducted on the analysis of mangrove vegetation on the coast of Bama, the Baluran National Park Situbondo Regency, in February 2021. The purpose of this study was to identify mangrove vegetation on Bama beach. Mangrove sampling is done purposive sampling by making plots on transect lines intermittently. Sizes 20 x 20 m2 for trees, 10 x 10 m2 for poles, 5 x 5 m2 for stake and 2 x 2 m2  for seedlings. Each plot identified the type and measured the diameter of the trunk and the number of individual mangroves. Important value index (IVI) is obtained by calculating species density, relative density, type frequency, relative frequency, type dominance, and relative dominance. The results showed that on the coast of Bama Baluran National Park, there are four types of mangroves, namely  Rhizophora apiculata, Rhizophora stylosa, Ecoecaria agallocha, and  Terminalia catappa, where  Rhizophora stylosa is a species that dominates.

Abstract

The environment as a place where living things live has undergone significant changes which have resulted in a decrease in environmental quality. The level of students' understanding and awareness of the environment greatly influences the existing environmental conditions. However, the fact is that environmental knowledge possessed by students has not been fully applied in their environment. This study aimed to ascertain the relationship between students' environmental knowledge and environmental attitudes. This study employed a survey method with a correlational design for its research. Class X MIPA students from SMA Negeri 1 Banyuputih comprised the entire study population. The technique of sampling employed is saturated sampling. The data collection technique is by using a questionnaire on environmental knowledge and environmental attitudes which contains statements based on a Likert score. Students' environmental knowledge correlated with their environmental care attitude, with a Sig. 0.00 < 0.05.
