ABSTRACTThis study was conducted to determine the effectiveness of the addition of the cow rumen fluid content of organic waste in producing biogas as a handout biotechnology development in the field of animal husbandry in the high school class XII., The study was conducted in March-April 2015.This research was carried out by two phases: biogas production using experimental research and development stage handout. Experimental study was conducted using completely randomized design (CRD), which consists of 4 treatments and 3 replicates in order to obtain 12 experimental design. If there is a difference between treatments meal test Duncan Multiple Range Test (DMRT) at 5%. The parameters observed biogas volume, pH dan temperature. The addition of the cow rumen fluid content of 250 ml best produce biogas. Where produce biogas volume as much as 447.68 cm³, pH 6, the temperature of 35ºC. Results of the study was developed as a handout that the material application of biotechnology in the field of animal husbandry.Key Words: biogas, fluid rumen cows, handout, trash organic biogas, fluid rumen cows, handout, trash organic

A surveys of three station along the nesting beach for distribution nesting analysis with beach characteristics and microclimatic nesting green turtles Chelonia mydas in Pulau Jemur-Riau was conducted in April- July 2002. The spatial distribution along the nesting beach namely the nesting abundant at highest the beach slope are 24°-31°, the grain sizes are medium sand (MZ = 2,18) and coarse sand (MZ =1,34). Temporary distribution in the nesting begins in April, extends through May and June, and decreases during July. The coral stones are limiting factor for landing beach success. The characteristic of nesting (beach slope) indicate microclimatic effect on nesting and impacted for distribution was reducing abundant of nesting. Canopy vegetation at highest beach slope are 30° had microclimatic effect on nesting. Key words : Distribution, microclimatic, nesting, green turtles, Pulau Jemur
