This study aims to determine the diversity of macrobentos that exist in the turtle conservation pond University of Bengkulu which serve as a source of learning science class VII MTsN 2 Bengkulu City. This research was conducted in February 2017 until May 2017. The sampling of macrobentos using a quadrant transect measuring 1x1 meter made of 6 quadrants. Based on the results of research conducted obtained 1,086 individuals belonging to macrobentos belonging to 3 genus namely, Bellamnya, Faunus, and Pomaceae. The data obtained were calculated based on macrobentos community structure consisting of population density (KP), relative abundance (KR), presence frequency (FK), Diversity Index (H ') and dominance index (C). The macrobentos diversity index found in turtle conservation ponds is below 1.5, with the result it can be said that in both turtle conservation ponds it has low macrobentos diversity. Development of learning refers to the modified Dick & Carey model. The lessons developed include Syllabus, RPP, LKPD, and performance appraisal instruments that are viewed from the students' process skills. The result of the validation of learning development shows that the teaching materials developed are very feasible in the test try to learners. The results showed that the average of students' process skills from the aspect of the highest performance performance was in good criteria. This is indicated by the percentage that reaches 67%. While the criteria include very good reached 33%. While for the result of measurement of process skill of student which counted by classical which counted on each indicator included into good category and very good.

The goal of this research was to determine the content of secondary metabolites and the most active fraction of Simbagh Utak (Hydnophytum sp.) Tuber extracts. The content of secondary metabolites is determined by using phytochemical tests, and toxicity tests are carried out by the Brine Shrimp Lethality Test (BSLT) method. Hydnophytum bulbs from Jukung Village, Lubuklinggau City, South Sumatra were macerated using 96% ethanol and then evaporated until thick extracts were obtained. This thick extract was then tested for secondary metabolite content, fractionated using n-hexane, and ethyl acetate. The results of the fractionation were then carried out a toxicity test using the BSLT method. Secondary metabolite test results showed ethanol extract containing flavonoids, alkaloids, tannins, saponins, terpenoids, and phenolics. The result of fractionation was obtained by the tuber extract of Hydnophytum n-hexane fraction, ethyl acetate fraction, and ethanol fraction. Toxicity test results obtained LC50 values of n-hexane fraction of 52.3 ppm, LC50 of ethyl acetate fraction of 45.9 ppm, and LC50 of ethanol fraction of 99 ppm. All Hydnophytum tuber extract fractions were categorized as toxic and have potential as anti-bacterial or anti-oxidant. The fraction that has the lowest LC50 price is the most toxic fraction. The most toxic fraction is the most active fraction. The ethyl acetate fraction was the most active fraction because it has the lowest LC50.

ABSTRACT[Study of Kuya Batok (Cuoro Ambonensis) Early Growth’s in UNIB Forestry Pond and its Implementation as Teaching Materials on Vertebrate Zoology]. The goal of this study was to know the growth of C. amboinensis in the ex-situ conservation area of the University of Bengkulu Forestry Pond during the 10 weeks study and 3 weeks continuous research, to know the condition of abiotic factor C. amboinensis in ex-situ conservation area of Forest Ponds of Bengkulu University, and to know the knowledge and understanding of the students about the early growth of C. amboinensis, the conservation concept at the University of Bengkulu Forestry Pond and the change of students conservation attitude by using teaching materials. Implementation of learning adoption of existing teaching material products "Technique Monitoring of Black-turtle Lineage of Coldhamii" (Astuti, 2016). The teaching material is in the form of a book entitled "Monitoring Technique of Turtle Shell (Cauro amboinensis)". The results of this study show that: a) The first study only received 1 C. amboinensis for 10 weeks of observation and growth (weight, length, width, thickness, anterior-posterior arch, b) Abiotic factors in the conservation area supported growth of C. amboinensis and suitable for in situ conservation pond ex situ in UNIB, c) On the second observation release 15 C. amboinensis by using 3 large trapp to conservation pond for 3 weeks and experiencing growth, d) condition of abioic factor become habitat C. amboinensis include: ground temperature 280C, water temperature 300C, relative humidity 80%, soil pH 6, pH 7 water, turbidity 80, e) high knowledge of students about the existence of turtles 22.8% - to 77.2% on conservation 13% to 87%, not in line with the conservation attitude of 34% to 66%.Keywords: Growth; C. amboinensis; abiotic factor; teaching material.

This study aims to inventory the type of necton, knowing the structure of the necton community and measuring the critical thinking skills of students of class VII.1 SMPN 1 Ujan Mas Kepahiang. The results showed that the necton obtained from the Taman Pintar pond amounted to 7 species and Pipi Putih Pond totaling 4 species. The necton species in the Taman Pintar pond with the highest KP, KS, and FK values are tin head fish with KP, KR, and FK values respectively 0.102 idv / m2, 75.71% and 83%. While on the Pipi Putih Pond is local catfish species with the value of KP, KR, FK of 0.01 idv / m2, 39.29% and 25%. Then dominance index (H ') in the Taman Pintar pond is 0.61 and C' Pipi Putih pond = 0.76. While the index of diversity of necton species in both ponds also belonged to very low category with H’ value of Taman Pintar Pond = 0.28 and H' of Pipi Putih pond = 0.17. The result of Percentage Of Agreement test showed that environment-based learning tools developed are included in the category highly feasible to be tested. Students’ critical thinking ability on the perpormance aspect shows 33 ,3 % percentage including critically critical criteria and 66,7 % including critical criteria. While Students’ critical thinking ability on the cognitive aspect shows four criteria, that are very critical as 26 %, crittical criteria 40 %, criteria critical enough 27 % and criteria less 7 %
