Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan model pembelajaran learning cycle dalam meremediasi miskonsepsi siswa kelas VIII SMP Muhammadiyah 2 Pontianak pada pokok bahasan tekanan zat cair. Metode yang digunakan berupa pre experimental design dengan rancangan one group pretest posttest design. Instrumen dalam pengumpulan data berbentuk pilihan ganda tanpa alasan yang diujikan pada 29 orang siswa yang dipilih secara intact group. Hasil analisis data diperoleh persentase rata-rata miskonsepsi yang dialami siswa pada saat pretest 63,18 % dan pada saat posttest 24,13%. Hasil uji Mc Nemar diperoleh tabel (3,84) lebih besar dari hitung untuk dk = 1 dan α = 5% maka secara keseluruhan terjadi perubahan konseptual yang signifikan dan harga proporsi penurunan jumlah miskonsepsi diperoleh nilai 0,62 (kategori sedang).

The method used is pre-experimental with one group pretest posttest design. The data collecting instrument was a multiple choice test without explanation, which was tested to 29 students sampled by using intact group. The result shows that the students’ average misconceptions in the pretest and posttest are 63,18% and 24,13% respectively. Mc Nemar test obtained X2table (3,84) bigger than X2 count for dk = 1 and α = 5%, therefore, overall there is a significant conceptual improvement and the proportion value of the decreasing number of misconceptions is 0,62 (moderate). As the result, remediation by using the Learning Cycle Model is effective to decrease the number of students’ misconceptions. This study is expected to be used as an alternative way of implementing remediation to the students’ misconceptions on liquid pressure. Keywords: Effectiveness, Remediation, Learning Cycle

Abstract

This study aims to examine the toxicity of A. marina leaf extracts to subterranean termite C. curvignathus and to determine the optimal concentration of A. marina leaf extract in inhibiting termite attack. A. marina leaf powder was extracted using methanol solvent for 48 hours, then the extract solution was evaporated using rotary evaporator for 1 hour to obtain extract in gel condition. Then whatman paper immer in extract solution at each concentration of 0%, 1%, 2%, 3%, 4% and 5% for 1 hour. Testing was done for 21 days. The parameters observed were termite mortality and weight loss of whatman paper. The highest mortality was found at concentrations of 5% with mortality of termite reach 100% with the weight loss of 0,857%. Concentration of 2% was noted as the optimal result with termite mortality value of 86,66% and weight loss of whatman paper reach 34,0725% wiht the level of anti-termite activity classified as B (strong). Keyword : Api-api leaf, Coptotermes curvignathus, extract, toxicity
