Sumber Makmur Mason Group
Sumber Makmur Mason Group is a mason group that is located in Rejotangan Sub-district, Tulungagung. Geographically, it lays on the borderline of Tulungagung and Blitar and it makes them able to cover several sub-districts in the two districts. Initially this group only served the requests from members of KUD Sumber Makmur Rejotangan, but because of the potential user of BIRU is less than before, the mason group must expand their coverage to another sectors and areas such as beef cattle breeders and dairy cattle in other districts like Ngglegok, Garum, Lodoyo, Kanigoro and Kademangan Sub-district in Blitar and Kalidawir, Pucanglaban and Tanggung Gunung Sub-district in Tulungagung.
