Judul: Analisis Indeks Baseflow Daerah Aliran Sungai Bengawan Solo
Abstrak: Study about baseflow characteristics in Java Island remains research challenge especially to correlate biophysical characteristics of watershed with long term streamflow observation. This study aimed to know baseflow characteristic of Bengawan Solo watershed which physically grouped as one of critical watersheds in Java Island. We analysed daily streamflow data 1980-2010 to calculate baseflow index (BFI) based on smoothed minima method. We compared non-overlapping 3 days, 5 days, and 7 days of streamflow to calculate BFI. The results showed that higher N days would generate lower BFI. Lower BFI meant less baseflow contributing on streamflow. We found that average BFI3d, BFI5d and BFI7d in period 1980-2010 were 0.67, 0.56 and 0.49. It showed that Bengawan Solo watershed has permeability of fissure with low storage. We also found that trend BFI, BFa, and Qann rise significantly (α = 5%) in period 1998-2010, while annual precipitaion indicated negatif trend

Judul: Analisis Tren Jangka Panjang Curah Hujan dan Debit Daerah Aliran Sungai Bengawan Solo
Abstrak: Bengawan Solo Watershed is classified as one of the most degraded watershed in Indonesia. The Watershed usually was utilized as water resource for irrigation, transportation and industry. The problems in the Bengawan Solo Watershed is deforestation, illegal logging and land conversion. This research aimed to find out trend of rainfall and streamflow in Bengawan Solo Watershed for period of 1980-2010. Twelve rainfall stations in the Watershed were chosen for rainfall trend analysis and calculating rainfall area. The trend analysis was divided into two parts that is before and after reformation era (year at 1998). Trend analysis was performed using Mann-Kendall test at 95% confidence interval (α= 5%). Research result showed that before reformation era we found there were no significantly trend for rainfall and annual streamflow. However, after reformation era we found that there was a significantly negative trend for rainfall at most stations, but significantly positive trend for average annual streamflow. Coefficient of runoff in Bengawan Solo Watershed range 0,4-0,81 and did not occur a significantly trend for this research.

Judul: Penyakit kudis pada kelinci ( Scabies ) dan cara penanggulangannya
Abstrak: Salah satu penyakit yang disebabkan oleh parasit terutama ektoparasit pada kelinci yang sering dijumpai adalah penyakit kudis. Kudis merupakan penyakit kulit yang sangat menular yang disebabkan oleh beberapa jenis tungau. Beberapa jenis tungau penyebab kudis yang telah diketahui antara lain Sarcoptes scabiei, Notoedres sp. dan Psoroptes sp. Hewan umur muda, hewan tua yang dipelihara dalam kondisi jelek merupakan faktor-faktor predisposisi bagi infestasi penyakit kudis. Infeksi meluas terutama oleh kontak dengan larva, nympha dan betina yang bunting. Tungau sangat peka terhadap kekeringan dan tidak dapat hidup lama pada hostnya dalam keadaan tersebut. Dalam penyebarannya lebih menyukai bagian tubuh yang tidak ditutupi banyak bulu seperti kepala dan telinga. Gejala klinis yang ditimbulkannya antara lain hewan menampakkan rasa gatal, gelisah dan selalu menggaruk-garuk badannya, kulit merah, menebal, ada exudat, bulu rontok dan kulit menjadi gundul. Apabila kasusnya parah maka hewan bisa mengalami kekurusan, dehidrasi dan akhirnya terjadi Kematian. Diagnosa didasarkan atas gejala klinis. Selain itu untuk lebih meyakinkan diagnosa dilakukan pemeriksaan mikroskopis dari bahan kerokan kulit. Tindakan pencegahan mencakup penempatan hewan di kandang yang bersih dan hangat, memberi makan yang bergizi baik. Untuk pemberantasan populasi tungau diperlukan tindakan isolasi hewan sakit, bulu-bulu atau rambut dicukur kemudian bagian kerak-kerak yang tebal dibersihkan dengan sabun dan air hangat dan dijaga terhadap kontak dengan hewan yang sehat. Obat-obat yang sering digunakan antara lain emulsi belerang, benzyl benzoat, Lindane, Tetmosol, Coumaphos dan Ivermectin.
