Abstract

This research aimed to identify the influence of two learning models and learning reliance on students’ scientific literacy. The method used was the treatment by 2 x 2 level. The participants were 36 students from the Department of Biology Education who were grouped into two categories based on the reliance questionnaire score, i.e., categories of high and low. The data were collected through scientific literacy tests, data analysis using two-path ANOVA formula followed by the Tukey test. The results showed that there was an influence on the interactions between the learning models and learning reliance on students’ scientific literacy seen from the ANOVA test results which obtained F = 29.88, =0.05. The Tukey test analysis identified; (1) Scientific literacy of college students who used the Science, Technology, Society (STS) model was higher than those who adopted the Problem-Based Learning (PBL) Model with Q = 4,74 at =0.05; (2) The scientific literacy of students having high learning reliance using the STS learning model was better than those applying the PBL with Q = 11,78 at =0.05; (3) The scientific literacy of students having low learning reliance using the STS learning model was lower than those using the PBL with Q=5.07 at =0.05. It concluded that the STS learning model could improve the students’ scientific literacy. In other words, the STS learning was more useful for the high reliance students than those with low reliance.

Abstract

Penambahan hidrogen peroksida pada media air untuk mempertahankan hidup ikan kerapu lumpur (Epinephelus suillus) telah dilakukan dengan tujuan untuk mengetahui pengaruh hidrogen peroksida terhadap kualitas air media ikan kerapu lumpur. Penelitian ini terdiri atas 2 tahap. Tahap 1 yaitu penggunaan berbagai konsentrasi hidrogen peroksida dengan volume 0,5 ml. Pada penelitian tahap 2 menggunakan konsentrasi hidrogen peroksida terpilih dengan perlakuan volume hidrogen peroksida. Berdasarkan hasil penelitian didapatkan konsentrasi hidrogen peroksida terpilih adalah 13,6 %. Untuk ikan ukuran 60-80 gram yang mampu mempertahankan ikan hidup lebih lama adalah 1ml selama 953 menit, sedangkan untuk ikan ukuran 100-150 gram yang paling lama hidupnya pada volume 1,5 ml yaitu 3107 menit. Penambahan hidrogen peroksida pada berbagai konsentrasi dan volume tidak menyebabkan perubahan kualitas air secara bermakna, kecuali untuk oksigen terlarut yang semakin meningkat.Kata kunci: hidrogen peroksida, kerapu lumpur, kualitas air
