Farm poultry, especially chicken, is a producer of meat and eggs. In addition to producing meat and eggs, chicken farms also have negative impacts, which can cause odorless gas that can pollute the environment. In the village there are six places Srikaton laying chicken farms that always make chicken manure every day. Alternative technology that can be applied and has a positive outlook is to convert poultry farm waste, ie chicken manure into compost. IBM outer target groups laying chicken farming is to produce compost chicken that can be utilized by the villagers Srikaton (short-term targets), and the long-term target is to sell the compost to other consumer good in the village Srikaton, and outside the village Srikaton. Effective technology for the transformation of society is using extension methods, training by making demonstrations, or direct practice coupled with mentoring. The target of this service is Srikaton village community, which consists of chicken breeders, youth organization group, the PKK, and residents who do not have a job (unemployed). Based on the activities carried out, the people were very enthusiastic. Through these activities, the village Srikaton has the skills to produce compost chicken manure that can be used for fertilizer in the garden itself, and or for sale, so as to improve their welfare.

Biodiesel is an alternative fuel for diesel machines. Used cooking oil is blended with diesel with a certain volume ratio to improve the characteristics. The characteristics of biodiesel can not be fully used by diesel engines because it doesn’t meet the standards so that its characteristics need to be improved. As for utilizing it, it must be blended with diesel oil. The purpose of this study is to improve the physical and chemical properties of biodiesel, knowing the percentage of biodiesel volume from used cooking oil with diesel oil so that it can be known the optimal ratio of biodiesel with diesel oil which is close to diesel fuel specifications. Characteristics as variables in this paper are density, kinematic viscosity, pour point, and flash point of the specified mixture. The results show that the kinematic viscosity and density of the biodiesel-diesel mixture increase as the biodiesel mixture increases. Mixtures with higher biodiesel content have higher flash points. Mixing diesel with used cooking oil biodiesel may be of no use compared to diesel, but it can help in adjusting the viscosity, density, pour point, and flash point values according to applicable regulations.
