However, most students are indifferent to conservation or science education. This individual influence is the characteristics and dispositions students bring to learning, such as interest, effort, values, and perceived abilities. This study aims to determine the effectiveness of conservation education programs through nature club activities on students' knowledge of Javan slow loris and protected endemic animals. The research method is the experimental method, with the research design used as one group pretest-postest design; the data collection technique is done by test and observation. The results showed that the activities carried out were effective on students' knowledge of Javan lorises and protected endemic animals, as evidenced by the calculation of the N-gain score indicating that the average N-gain score (mean) was 0.614.ABSTRAK: Pendidikan konservasi dapat menambah ilmu mengenai hewan yang terancam punah salah satunya yaitu Kukang Jawa (Nycticebus javanicus) serta hewan endemik yang dilindungi yang ada di Indonesia, hal ini dapat dilakukan melalui program klub alam yang ada pada pendidikan konservasi.

The findings of this study indicate that the application of the integration of Islamic values in biology learning in SMA/MA can be made through several models, including (1) the Al-Qur'an integration model as a source of inspiration, namely placing the Qur'an at the beginning of learning as an umbrella of knowledge; and (2) the Qur'an integration model as a source of confirmation, namely scientific findings are to clarify what has been stated by the Qur'anABSTRAK: Ilmu sains termasuk Biologi mempunyai hubungan yang erat dengan pengetahuan Islam sehingga pembelajaran Biologi di sekolah semestinya tidak hanya dipandang sebagai monodisiplin ilmu yang berdiri sendiri, tetapi secara aksiologis memiliki sistem nilai yang berkaitan dengan disiplin ilmu lainnya.
