Attitude toward science is believed as one of the factors that can influence student learning outcomes. Therefore, information related to students attitudes towards science is important. This study aims to determine the effect of different levels of education and gender on students attitudes towards science. Student attitudes toward science were measured using a questionnaire instrument with a Likert scale that was adapted to the My Attitude Toward Science (MATS) instrument. Data were analyzed by descriptive analysis and Mann-Whitney test. In general, the results of the study indicated students showed positive attitudes towards science. Mann-Whitney test results also showed that the level of education has a significant effect on students' attitudes towards science statistically [U=4259.5; p<0.05]. Meanwhile, statistically, gender differences significantly influence students' attitudes towards science [U=4384.0; p<0.05]. The implication of this study is teachers could consider these results when they want to design instruction. In addition, this result is also important to preservice science teachers at the level of junior high school and senior high school to know the characteristics of the students attitude.AbstrakSikap terhadap pelajaran sains dipahami sebagai salah satu faktor yang dapat memengaruhi hasil belajar siswa.

Perkembangan biomolekuler yang cepat menyebabkan pemahaman mengenai konsep DNA perlu ditanamkan sejak awal, terutama pada siswa sekolah menengah. Konsep DNA dapat diajarkan melalui teknik isolasi DNA secara tradisional. Teknik ini dapat dilakukan dengan menggunakan peralatan dan bahan sederhana dan tanpa protokol yang rumit. Tujuan praktek ini adalah menggunakan teknik isolasi DNA secara tradisional dengan menggunakan bahan isolasi DNA berupa hati ayam yang mudah diperoleh, dan enzim protease yang diperoleh dari ektraksi mandiri sel daun pepaya. Pada akhir proses isolasi diperoleh DNA, namun DNA yang didapatkan merupakan gabungan antara DNA hati ayam dan DNA sel daun pepaya. Kesimpulan dari praktek ini adalah teknik isolasi DNA tradisional dapat dilakukan untuk mengisolasi DNA dari sel hati ayam meskipun tidak dapat dibuktikan secara meyakinkan bahwa DNA yang diisolasi itu murni hanya berasal dari DNA inti sel hati ayam. Kata kunci : teknik isolasi, dna, hati ayam, tradisional
