The Effect of Media Composition on the Growth of Earthworms (Lumbricus Terrestris) to Support the Learning Process on Annelida Material in Class X Semester I SMA

Abstract

The study was conducted to determine the growth of earthworms (Lumbricus terrestris) using artificial media and the use of research results to support the learning process on the concept of invertebrate growth as a support for the learning process on annelid material in class X semester I SMA. This research was conducted at the Biology Education Laboratory of Palangka Raya University from June to July 2018. This study used a completely randomized design with 3 types of treatment and 6 replications. The material used was 72 earthworms (Lumbricus terrestris) with an average biomass and body length. Organic material as a living medium, namely P0 control / soil without a mixture of manure, P1 soil 2 Kg + 2 Kg cow manure, P2 Soil 2 Kg + 2 Kg goat manure, P3 soil 2 Kg + 2 Kg chicken manure. The parameters measured were the length and biomass of earthworms for 7 days after the worms were introduced into the media (at the beginning and end of the study). Supporting parameters measured are soil pH, soil temperature and humidity. Data were analyzed using analysis of variance (ANOVA) followed by LSD (Least Significant Difference) at the 5% level. The results showed the highest increase in length and biomass of earthworms (Lumbricus terrestris) in treatment (P3) (chicken manure). The results of the research can be used to support the learning process in the form of Student Worksheets (LKS) in class X SMA.
