Get PDFThe purpose of this research was to find out the competence of scientific lieracy of student. The research design was using simple descriptive design, by using purposive sampling technique, as many as 197 students. The quantitative data were scientific literacy competence that was obtained from PISA test and the qualitative data were factors influenced that were obtained from questionnaire. The result of the research shows that the students’ had very low category with the score 19,6 ± 3,0. The score of female students was 26,0 1,79 significantly different with male student that was 21,2 1,18 and showed the difference but it very not significant. The factors that influence students’ were parents’ education background, home work of students, the learning process including the length of studying science at school, participation in attending lesson and teacher who teaches the course. Thus, scientific literacy competence was “very poor” criteria and there were factors that affected that. Then significantly differences between male and female students competence.

Pengaruh Variasi Pengolahan Cangkang Kerang Kijing Lokal (Pilsbryoconcha exilis lea) Terhadap Kadar Timbal Dan Kalsium
Get PDFThis study aims to find out the most appropriate processing variations in reducing levels of lead metal (Pb), find out the most appropriate processing variation to maintain the calcium (Ca) content of mussel shell, and provide information about the potential of processed mussel shells as animal feed. This study used a completely randomized design method (CRD) with 4 treatments, namely, processing steamed shells (BW0), boiled (CW0), sauteed (DW0) and fresh shells as a control (AW0). Based on the results of the analysis, the treatment that reduces lead content the most is processing of boiled shells (CW0) of 815,488 ppm. Based on the results of the study, it can be concluded that the boiled processing method is the treatment that removes the highest levels of lead metal (Pb) and the steamed processing method is the most appropriate method of processing calcium content in the shell. Penelitian ini bertujuan untuk mengetahui variasi pengolahan yang paling tepat dalam menurunkan kadar logam berat timbal (Pb), mengetahui variasi pengolahan yang paling tepat mempertahankan kandungan kalsium (Ca) cangkang kijing, dan memberikan informasi tentang potensi olahan cangkang kijing sebagai pakan ternak. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan 4 perlakuan yaitu, pengolahan cangkang dikukus (BW0), direbus (CW0), ditumis (DW0) dan cangkang segar sebagai kontrol (AW0). Berdasarkan hasil analisis, maka perlakuan pengolahan yang menurunkan kandungan timbal paling banyak adalah pengolahan cangkang dengan cara direbus (CW0) sebesar 815,488 ppm. Berdasarkan hasil penelitian dapat disimpulkan bahwa, metode pengolahan direbus adalah pengolahan yang paling banyak menghilangkan kadar logam berat timbal (Pb) dan metode pengolahan dikukus merupakan metode pengolahan yang paling tepat dalam mempertahankan kandungan kalsium pada cangkang.Kata kunci: analisis cangkang, kalsium, kijing kokal, pakan ternak, timbal, variasi pengolaha
