Abstract

Metacognition knowledge is needed in the problem solving process. This knowledge has not been much taught and practiced to students. The research intends to provide information about (1) the profile of students' metacognition knowledge, (2) relationships, and (3) the contribution of metacognition knowledge to cognitive learning outcomes. The research subjects were 143 students of class XI SMAN 10 Semarang with research design of mixed method-sequential explanatory. Written test as a source of quantitative data and the Metacognitive Activities Inventory (MAI-1) questionnaire as a source of qualitative data. The metacognition knowledge of students is on the criteria of "ok". The relationship with cognitive learning outcomes obtained from the product moment correlation test results, r = 0.983 and the correlation coefficient significance test, Fh = 4041,84. The conclusion, there is a relationship between metacognition knowledge on cognitive learning outcomes. Contributions to cognitive learning outcomes are very high, amounting to 96.63%. PBBL is effective in empowering and training metacognition knowledge in the learning process in the classroom.

Abstract

Penelitian ini untuk menganalisis keefektifan bahan dari biji dan daun kelor (Moringa oleifera) yang digunakan sebagai koagulan.  Pada penelitian ini mengambil sampel satu liter air sungai yang keruh untuk setiap percobaan. Sebelumnya air diukur dahulu dengan turbidimeter. Berdasarkan hasil penelitian penjernihan Air sungai dengan bubuk biji kelor didapatkan hasil 8,67 NTU untuk bubuk biji kelor 0.5 gram , 4.29 NTU untuk biji kelor 0.2 gram dan 3.07 NTU dengan biji kelor 0.1 gram. Hal ini artinya dalam praktikum penjernihan air dengan bubuk biji kelor yang telah dilakukan kualitas air bertambah jernih dan masih memenuhi persyaratan air bersih yang diperbolehkan. Dapat disimpulkan pula bahwa dalam penjernihan air 1 liter lebih efektif / idealnya dengan 0.1 gram bubuk biji kelor.
