Abstract

This study aims to: 1) measure whether there is the effect of applying the concept of learning through a wetland ecosystem approach to the environment in SMA 1 Wanaraya on student learning outcomes; 2) measure whether there are differences in the application of the concept of learning the wetland ecosystem approach to learning using the learning environment by not using the environmental approach in SMA 1 Wanaraya on student learning outcomes through the group process: 3) knowing whether there is a relationship between learning outcomes and skills think students learning process through the application of the concept of learning tools wetland ecosystems and the environment approach the learning process does not use environmental approach in SMA 1 Wanaraya. This study uses a variant analysis (ANOVA) on the first purpose. On the second purpose using Arikunto Category Analysis (1998) and Variant Analysis (ANOVA). And the third purpose of analysis used is correlation analysis and correlation criteria using reference analysis Sugiarto (1992). Results of calculations obtained that the adoption of the wetland ecosystem concept learning and the learning environment approach the implementation of research on SMA 1 Wanaraya affect the results of the assessment of student learning, no discernible difference from the value percentage and categories are better and influence the level of keaktifitasan think students who use approach to the environment and there is a weak relationship between learning outcomes but the students' thinking skills.

Abstract

Objective of this research were to know the tolerance rate of common carp to liquid waste of sasirangan industries, effect of liquid waste of sasirangan industries to common carp mortality , water quality media, and common carp gills under exposures in 96 hours. Method in this research was Static Bioassay.  Tolerance Limit Media (TLM) or Lethal Concentration 50 % (LC50) in 96 hours used to determine of common carp tolerance rate with toxicity test.   Before toxicity test, preliminary test be done for determination of  upper and lower limit concentration. Completely randomize design with 5 treatments and 3 replicates was used in this research.  Application of liquid waste concentration as the treatment was K without liquid waste (0%), A (4,5%), B (5,5%), C (6,5%), and D (7,5%).  The data analyzed by using Analysis of Variance (Anova), and Duncan Multiple Range Test (DMRT).          Result of the research showed that tolerance rate of common carp to liquid waste (LC50-96 hours) was in concentration 4,9%.  Mortality rate was 0%; 33,33% and 76,66% for treatment K, A, and B respectively, but for treatment C and D reaches 100 %.    Anova and DMRT result indicated that liquid waste of sasirangan industries had significant effect (P< 0,05) to mortality rate of common carp.  Liquid waste also affect  water quality media such as temperature, pH, BOD, COD, NH3, Zn, and fenol, all of the parameters increasingly, except DO get decrease.  Based of histological analyze, liquid waste had impact to the gills. The  higher the liquid waste concentration makes the higher the damage rate.
