The research was held in July 8th to August 7th 2009 in Bocek village, Karangploso sub-district Malang Residence. The research aimed to find out economic application and analysis of Balloon Type Biogas and find out the energy resulted from baloon type biodiggester. Tools and materials used in the research were: (1) tools: cement, plastic, sand, water, brick, drum, paralon (0.5 dm and 0.4 dm), latex, wheel, ring, plastic glue, tap, band, and bamboo; Material: cow feces and water. Method used were experiment and survey presented observation in tables and descriptive analysis data and then analyzed in economic perspective. Biodiggester model built had specification as: wet material volume 12,56 m3. total volume 15,7 m3. 30 days process length. digester plastic with diameter 2m. Diggester hole, in form of wheel from paralon with 4 inches diameter, 450 declivity had different height between antara inlet and outlet 30 cm. Gas Volume 6,28 m3, diameter 2 m, length 2 m.Biodiggester resulted had simple construction. Balloon type plastic Biodiggester development could be considered cheap compared with concrete construction biodiggester. Temperature worked in Biodiggester ranged in 250C, as the temperature predicted in design phase. Acidity measured in material (6,5 – 7) still in good limit for bacteri to grow. Biogas production could be used for 3-4 hours cooking. It could be able to fulfill the needs of cooking 1,5 kg rice and 6 liters drinking water. Biodiggester investment was Rp. 1.465.500. The primary cost of balloon type biogas was Rp. 806.025. Biodiggester built had simple construction. The cost of building balon type plastic biodiggester was cheap compared with concrete biodiggester. Balloon type biogas biodiggester was good in household scale since it was cheap and efficient from economic dimension.
