Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan kotoran sapi terhadap kadar air beriket limbah baglog jamur tiram. Jenis penelitian ini adalah Eksperimen Murni. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dan analisis data yang digunakan yaitu ANOVA (Analisis of variance) pada taraf signifikan 5% dan diuji lanjut menggunakan DMRT (Duncan’s Multiple Range Test), dengan 5 perlakuan dan 4 ulangan. Kadar air yang diperoleh dari penelitian ini berkisar antara 2,73%-5,55%. Keseluruhan biobriket yang dihasilkan telah sesuai dengan SNI dimana kadar air pada biobriket menurut SNI (SNI 01-6235-2000) yaitu ≤ 8%. Berdasarkan hasil penelitian menunjukkan bahwa kadar air tidak berpengaruh pada pembuatan biobriket dengan menggunakan limbah baglog jamur tiram (0,05 > 0,05).
Self-efficacy is one of the factors driving the success of student learning. This study aims at analyzing the effectiveness Biology Integrated Learning (BIL) program with local wisdom in area of TNGR (Mt. Rinjani National Park) Lombok to improve students’ self-efficacy. The participants of this study were 140 students consisting of students on Biology Education and Biology Program in Mataram University and IKIP Mataram. The study uses a pre-experimental type with one-group pretest and posttest design. The effectiveness of BIL Program was measured by using self-efficacy scale. Self-efficacy data was converted into interval data and analyzed using paired t-test/wilcoxon test and n-gain calculations. The result of this research showed that BIL Program was effective to improve students’ self-efficacy in terms of (1) there are increase score of self-efficacy at a = 5%, (2) n-gain mean was in moderate category of .22 to .38. Thus, BIL program can be used as an alternative approach for improve students’ self-efficacy in biology learning.
