Abstract

The purpose of class action research is to increase the students activity on buffer and salt hydrolysis by using cooperative learning type sending greeting and question. The students of class XI IPA MA Al-Khairaat Gorontalo city as the subject of the research fourteen (14) people, consist five for boys and nine for girls. T6he successful qualification of this research are : (1) minimum 75 % from all the teacher activity and students that observed achieve the target, (2) minimum 80% of students thet gooten action get mark 6,5 upper with the understanding of material average 65%. Students activity in learning process is influenced by the result of students learning. Presentate average of students activity in cycle I : 27,88% get excellent, 51,07% get good, 17,86% get intermediate, 3,57% get bed. The result of students learning 71,43% with the understanding of material 64,8%.

Abstract

Penelitian ini merupakan suatu eksperimen laboratorium yang bertujuan untuk menganalisis protein yang terdapat dalam ikan Nike. Penetuan kadar protein yang dihitung adalah persen nitrogen total, kemudian dikalikan dengan faktor konversi, hingga didapat kadar protein kasar pada ikan Nike yang dianalisis. Penelitian ini dilanjutkan dengan melakukan identifikasi adanya asam amino melalui metode Kromatografi Kertas. Hasil penelitian menunjukkan perbedaan kadar protein pada ikan Nike dari hari pertama dan hari Terakhir kemunculannya. Kadar protein kasar pada ikan Nike hari pertama yaitu 2,7315 % sedangkan pada hari terakhir yaitu 4,083 %. Hasil identifikasi diduga di dalam ikan Nike terdapat asam-asam amino esensial yaitu Leusin, Isoleusin, Metionin dan Threonin.
