Abstract

Regarding the implementation of the current 2013 curriculum, students are required to play an active role in learning various kinds of texts, especially short story review texts. This study aims to find out (1) differences pretest and posttest using the problem posing model on learning to write short story review texts in class XI A2 SMAN 1 Cikalongwetan; (2) differences in aspects of the elements / systematics and language rules in the short story review text pretest and posttest using the problem posing model on learning to write short story review texts in class XI A2 SMAN 1 Cikalongwetan; (3) the effectiveness of the problem posing model in learning to write short story review texts in class XI A2 SMAN 1 Cikalongwetan. The method used in this research is pre experimental design with form (one group pretest-posttest). The sample taken was 28 students. The results showed an average initial test score of 46.25 and an average final test score of 78.57 which meant that posttest was better than prettest. There are significant differences in aspects of the content details and elements / systematics of short story review texts. Based on the results of the paired sample t-test, the Sig (2-tailed) value was 0,000 <0,05. Thus, the problem posing model is effective in learning to write short story review texts.

Abstract

Telah dilakukan analisis kandungan logam berat mangan dan nikel pada sedimen di sekitar Pesisir Teluk Lampung. Konsentrasi logam mangan dan nikel ditentukan menggunakan Spektrofotometer Serapan Atom (SSA) dengan tiga validasi metode yaitu limit deteksi, presisi (ketelitian) dan linieritas. Hasil penelitian menunjukkan bahwa konsentrasi logam mangan di Pesisir Teluk Lampung, yaitu sekitar 106,01 ppm hingga 107,69 ppm. Hasil analisis menunjukkan bahwa konsentrasi logam mangan pada sedimen tertinggi terdapat di Pesisir Sungai Way Kuala yaitu sebesar 107,69 ppm dan konsentrasi terendah di Muara Sungai Way Kuripan yaitu sebesar 106,01 ppm. Sedangkan konsentrasi logam nikel di Pesisir Teluk Lampung yaitu sekitar 68,8 ppm hingga 71,46 ppm. Hasil analisis logam nikel pada sedimen tertinggi terdapat di sekitar Pemukiman Penduduk Bumi Waras yaitu sebesar 71,46 ppm dan konsentrasi terendah di Pesisir Sungai Way Kuala yaitu sebesar 68,8 ppm. Nilai konsentrasi logam berat mangan dan nikel  yang diperoleh dalam  penelitian ini masih berada pada batas normal standar baku mutu logam berat pada sedimen yang telah ditetapkan oleh The Ontario Ministry Of The Environment. Validasi metode pada penentuan kadar mangan dan nikel dalam sedimen menunjukkan presisi dengan nilai relatif standar deviasi (RSD) < 5 %, limit deteksi logam mangan dan nikel masing - masing adalah 0,021 ppm dan 0,018 ppm; serta nilai koefisien korelasi mangan dan nikel adalah mendekati 1.
