Abstract

A study using Research and Development design was conducted to produce a model of Biology hand book writing which is ecology and local oriented as an effort to increase students’ care toward environment. The background of this research is the reality which is  still going on untill now that the awareness and care of the school graduatee toward the environement safety is still low. Besides, hard science instructional at school could not affect or intervene the graduatee’s characteristics, for instance in keeping the environment awareness. Meanwhile, there are many concepts of environment which had been taught through hard science especially biology, so in the researcher’s point of view, biology subject has strategic role to prevent or mitigate the environment disaster caused by human activities. The model was validated at beach  ecosystem. The analysis of the research result includes three aspects, namely: 1) text comprehension, 2) environment care attitude, and 3) handbook readibility. Based on the result of beach ecosystem data analysis, it was found that (1) there was a significant difference between experimental class and control class in the beach ecosystem which is shown by tcalculation > ttable (7.429 > 2.00); (2) there was strong correlation between students’ comprehension and attitude which is shown by coeficient correlation (r) 0.634. While the text readability test (Cloze test) shown  the readability of beach ecosystem text is 57,57% (moderate). Therefore, it can be concluded that all of the texts in the developed book are fit and proper for SMA students of grade X. Kata kunci:  Penulisan buku ajar, orientasi ekologi dan lokal, kepedulian terhadap  lingkungan.

Abstract

Coral reefs are vital coastal ecosystems that provide significant ecological and economic functions, supporting the sustainability of ecosystem services in coastal areas and small islands. The coral reef ecosystem on Tunda Island, Serang Regency, Banten Province, is currently experiencing degradation due to pressures from anthropogenic activities, such as destructive fishing practices, industrial operations, and tourism intensification, all of which potentially disrupt the marine ecosystem’s balance. This study aims to analyze the condition of coral reefs in Tunda Island by assessing substrate cover percentage, life form composition, and community structure. Data were collected using the Underwater Photo Transect (UPT) method at four stations at depths of 4 m and 8 m. Transect photos were analyzed using CPCe software, while community structure was assessed using diversity (H’), dominance (D), and evenness (E) indices. Results showed that the average live coral cover was only 16.92%, categorized as poor. Life form composition was dominated by Non-Acropora corals, particularly massive, branching, and foliose types. Community structure analysis indicated moderate diversity (H’ = 2.29), low dominance (D = 0.17), and high evenness (E = 0.7), suggesting a relatively stable community despite low coral cover.   Keywords: coral reef; community structure; Tunda Island
