STUDI MORFOGENESIS KOKON CACING TANAH (Pontoscolex corethrurus) SEBAGAI BAHAN LIFE SKILL SISWA

Abstract

Abstract: The objectives of this research were to: (1) study the optimum regeneration cultivation method of earthworm (Pontoscolex corethrurus), (2)understand the developmental phases of morphogenesis in P. corethrurus cocoon, and (3) utilize the research results as a life skill learning material for junior high school students. Experimental research was conducted, which also serves as practical experience for the students. In this research, morphology, anatomy and biochemistry of three developmental stages of morphogenesis of P. corethrurus cocoon were observed and directly examined. P. corethrurus can be cultivated in the optimal medium homeland worms fed with dried cow dung. P. corethrurus morphogenesis cocoon consists of four stages namely; darkish, white, red, and hatch. The weight, diameter, protein, and fat reduced in line with morphogenesis. Implementation of worm farming skills to the junior high school students real-life skills beneficial to improve in real life.
