The impact of land use change is the loss of 4848.5345 tons of rice production is lost or an average loss of about 449.87 tonnes per year. Meanwhile, the value of lost production amounted to Rp19794138,000 or Rp1799468000 per year. Resulting in a difference between the need for food consumption for rice production which amounted to 384.63 tons / day where the average production of rice by 12.04 tons / day, while consumption amounted to 396.67 tons / day

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before.
