Abstract

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.

Abstract

This study aims to explore perceptions related to the learning process and students' needs for environment-based learning media in the Biology Education Study Program at PGRI Silampari University. The method used is survey research with research samples, namely students who take Environmental Science courses and lecturers of the course. The study results show that the teaching-learning process in Environmental Sciences only takes place in the classroom using E-Books and relevant materials packaged in PPT as teaching material sources due to limited time for lectures. Student perceptions and criteria for the development of learning media from lecturers refer to the packaging of learning media products that contain information related to Environmental Science with the right material objectives and concepts, are easy to understand, interactive, easy to use, contain animation and media display must be attractive. In conclusion, it is necessary to develop learning media to make the learning atmosphere more fun, interactive and exciting, one of which is through the development of Learning Blog media.

Abstract

Pteridophyta plants as plant communities in biodiversity have important ecological functions in rivers and human life. One of the habitats for ferns in the upper reaches of the river in Bengkulu is the Pasmah River. The Pasmah River is a source of water for the people of Bengkulu and its surroundings. To maximize the role of the river, it is necessary to make an inventory of plants around the river, one of which is ferns. This study aims to determine the diversity of types and variations of pteridophyta sorus. A sampling of ferns was carried out on the banks of the Pasmah River, Central Bengkulu. Purposive sampling was used in this study to pinpoint the location, and the cruising (cruise method) was used to collect sample data. The results showed that there were 15 types of ferns where 12 types of ferns were found with sorus, 6 types of ferns were round, 4 were elongated, 1 was in line, 1 was strobili and 3 species had no sorus.
