Abstract

This study aimed to: 1) develop students' science process skills class X2 SMA Muhammadiyah 1 Metro. 2) enhance students' cognitive learning outcomes X2 class SMA Muhammadiyah 1 Metro. Subjects in this study were students SMA Muhammadiyah 1 X2-class Metro Lesson Year 2011/2012 on the subject matter of the world of plants (Plantae). The study was conducted on February 1 until March 7, 2012 to be implemented in two cycles. Each cycle of meetings held 3 times. The conclusion of the research are there was an increase from cycle I to cycle II . While the cognitive learning outcomes of students has increased from pre-PTK into the second cycle. In the pre-PTK is increased 60.6% to 65.3% in cycle I, and from cycle I is 65.3% increased to 77.2% in cycle II. Based on data from the study of learning with model-based learning environment to develop science process skills and improve cognitive learning outcomes in students, researchers therefore suggest to teachers to implement this model in the study of biological science. Kata Kunci: model pembelajaran berbasis lingkungan, keterampilan proses sains, hasil belajar kognitif

Abstract

This study aims to get a dose of the best concentrations of liquid waste in order to produce rapid mycelial growth and production of white oyster mushrooms with optimal fresh weight. In this study using Analysis of Variance (ANOVA) One Direction with four treatments, each treatment be repeated six times. The treatments tested were (A) the concentration of liquid waste 25%/L water/ treatment, (B) the concentration of liquid waste 30%/L water/treatment (C) concentration of liquid waste 35%/L water/treatment and (D) control. The results showed that the concentration of industrial wastewater know 25%/L water/highest treatment effect on the growth and production of white oyster mushroom (Pleurotus ostreatus) with a mean weight of 129.33 gr fresh row A; B 105.5 gr; C 76.17 gr; and D 90.83 gr. The results could be used as a source of learning biology at the high school level with the subject matter of the class X Waste and Recycling Waste. In addition, this study also can be a reference for researchers and the general public. Kata Kunci: limbah cair, jamur, produksi, biologi.
