This research was conducted at the Natural Laboratory of Education and Teacher Training University of Riau in April to June 2013. This study used a completely randomized design with 9 treatments and 3 replications. The material used is the earthworm (Lumbricus rubellus) as much as 270 worm with averaged biomass and body length. Organic materials as artificial feed (P1) tofu, (P2) kakawatan grass, (P3) chicken manure, (P4) cow manure, (P5) tofu + chicken manure, (P6) + kakawatan grass + tofu, (P7) chicken manure and kakawatangrass (P8) + cow manure + tofu. Parameters measured were the length and biomass of earthworm for 60 days after planting (at the beginning and end of the research). Proponent parameters measured were pH of soil, temperature of soil and moisture. Data were analyzed using analysis of variance (ANOVA) followed by DMRT (Duncan Multiple Range Test) at the level of 5 %. The results showed increase length and biomass of earthworm (Lumbricus rubellus) is highest at (P4)treatment (cow manure) which is 0.214 g/tail, long worms present in the (P2) treatment (kakawatan grass) which is 4.99 cm and the lowest on all parameters is the (P0) treatment (no treatment). The results of the research can be used to support the learning process in the form of Student Worksheet (LKS). Keywords : Lumbricus rubellus , Growth, Artificial Feeding, LKS PENDAHULUAN Kehadiran cacing tanah di dalam habitat tanah sangat menentukan dalam penghancuran sampah nabati menjadi humus, mengubah profil tanah dan membuat lubang- lubang tanah atau aerasi tanah sehingga oksigen dapat masuk ke dalam tanah untuk kehidupan hewan tanah lainnya. Cacing tanah membantu mempercepat proses mineralisasi yang terjadi di tanah karena dapat menyediakan substrat yang baik bagi organisme serta butiran-butiran kascing dapat memperbaiki struktur tanah. Pertumbuhan cacing tanah sangat bergantung pada jenis pakannya, pertumbuhan cacing tanah akan meningkat bila pakan tersebut banyak mengandung bahan organik. Pakan utama cacing tanah adalah bahan organik yang dapat berasal dari serasah daun (daun yang gugur), kotoran ternak atau bagian tanaman dan hewan yang sudah mati (Suin, 1997). Saat ini limbah peternakan, limbah pertanian, limbah rumah tangga dan industri terdapat dalam jumlah yang sangat melimpah. Hal ini akibat dari pengembangan usaha pada sektor peternakan dan pertanian. Apabila limbah ini tidak

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
