Abstract

Aquaculture can be improved by a diversified approach in the form of domestication research of a wild fish. The research has been done by cultivating Javaen Barb/Brek (Puntius orphoides) from Serayu river, Banyumas at a natural pond and laboratory scale. Brek fish is relative slow in growth and development of gonad. This research is aimed to determine: (1) the rate of general growth of Brek in the provision of some kinds of additional food; (2) Relative Growth Rate (RGR); (3) Specific Growth Rate (SGR) and Feed Conversion (FC). The research used experimental methods. The method was a completely randomized design (CRD) of 4 treatments and 3 replicationsof: A = 100% pellet; B = 70% soybean sprout and 30% pellet; C = 70% Ipomoea aquatica leaf and 30% pellet; D = 35% soybean sprouts, 35% I. aquatica leaf and 30% pellet. Quantitative data were analysed by analysis of variance (ANOVA) of the fishes growth.The results show influence of feed types to the Relative Growth Rate (RGR) of Javaean Barb. The best RGR with the value of 72.40 was given by feed types in the D combination. Meanwhile, Specific Growth Rate (SGR) and Feed Conversion (FC) were not affected by the feed types. The study were expected to provide suggestions for efficient feeding techniques in attempts at domestication of wild fish.How to CiteSusatyo, P., Sugiharto, S., Hana, H., & Chasanah, T. (2016).

Abstract

Abstract The general problem in this study whether using the problem based learning model can increase student activity in class III civic education subjects SDN 06 Pereges, Seluas District? The general objective of this study is to improve student learning activities by using a problem based learning model on the subjects of class III citizenship education at SDN 06 Pereges, Seluas District. This study uses descriptive methods with the form of classroom action research, and the nature of research is collaborative. The research setting took place at SDN 06 Pereges, Seluas Subdistrict, with research subjects, namely class III B students totaling 24 people. Data collection techniques used are interview techniques, direct observation techniques, measurement techniques with data collection tools namely observation sheets. The data collected is analyzed with percentage and average calculations.This research was conducted in 3 cycles. The ability of teachers to design learning in cycle 1 obtained an average score of 3.39 with a good category, in cycle 2 experienced an increase of 0.25 to 3.64 with a very good category, and in cycle 3 had an increase of 0.13 to increase to be 3.77 with a very good category. The ability of teachers to carry out learning in cycle 1 obtained an average score of 3.45 with a good category, in cycle 2 experienced an increase of 0.11 to 3.56 very well, and in cycle 3 had an increase of 0.25 so it increased to 3.81 with a very good category. Student activity in cycle 1 obtained a percentage of 57.82%, in cycle 2 it increased by 7.36% to 65.18%, and in cycle 3 also increased by 13.54% to 78.72%. With the implementation of the problem based learning model in learning civic education can improve student learning activities. Keywords : Learning Activities, Problem Based Learning Â
