Judul: Dynamics of Social Institutions for Management of Inland Public Water Resources (The Lebak Lebung dan Sungai (L3S) Auction Case, in Ogan Komering Ilir District, South Sumatera)
Abstrak: Sebagian wilayah perairan umum lebak lebung dan sungai (PULLS) di Sumatera Selatan diatur dengan institusi pelelangan yang dilakukan sejak lama oleh masyarakat setempat berbasis marga yang saat ini disebut “lelang lebak lebung dan sungai” (L3S). Institusi pengelolaan lelang telah mengalami perubahan dari community-based management (CBM) menjadi governmentbased management (GBM) sebagai wujud pelaksanaan pemerintahan daerah otonom. Institusi pengelolaan saat ini membawa banyak perubahan, khususnya bagi keterlibatan aktor-aktor di dalamnya yang memicu marjinalisasi nelayan. Secara spesifik penelitian ini bertujuan menganalisis perubahan institusi pengelolaan L3S dari sebelum dan setelah perubahan pengelolaan, pelembagaan patronase yang terbentuk, serta dampaknya terhadap aspek ekonomi, sosial dan lingkungan. Penelitian ini menggunakan paradigma post-positivisme dan metode penelitian mix method dengan pendekatan kualitatif dan kuantitatif. Menetapkan 21 informan dan 31 responden sebagai subjek penelitian yang dipilih secara sengaja dan menganalisis data menggunakan tiga tahap yaitu reduksi data, penyajian dan penarikan kesimpulan dan penyajian data deskriptif skala ordinal pada data kuantitatif. Hasil penelitian menunjukkan telah terjadi dinamika institusi pengelolaan L3S yang membentuk relasi kerja baru dan berdampak pada kemiskinan berkepanjangan buruh nelayan, perluasan konflik sumber daya alam, serta degradasi sumber daya alam.

Judul: Pengelolaan Lelang Lebak Lebung dalam Pemanfaatan Perairan Umum di Kecamatan Rantau Bayur
Abstrak: Lebung lebak auction is a system of inland fisheries resources management in South Sumatra through an auction mechanism object consisting of the lebak, lebung, rivers, and soil decreases. Implementation in the District Banyuasin been implemented since 2005 and is set in the Peraturan Daerah Kabupaten Banyuasin No. 23 of 2005 about Lebak Lebung Auction. The method used is a case study with a descriptive analysis. Determination of the respondents were purposively. Based on research, there are some things that do not fit between the regulation and the implementation. The starting price of the auction begins Rp0,00. Pengemin just picked catching rent on bekarang from another village. There is a violation by one of the pengemin who catch using electric current. There are four aspects that were used to know how is management of lebak lebung auction on the concept of sustainable fisheries, which is ecology, economic, social, and institutional. Based on the implementation, the management of lebak lebung auction in Sub-District Rantau Bayur has not yet met the concept of sustainable fisheries.

Judul: Pengukuran Jantung Kelinci New Zealand White (Oryctolagus cuniculus) dengan Radiografi Toraks
Abstrak: This research was conducted to evaluate radiographs heart size of anaesthetized New Zealand White rabbits (Oryctolagus cuniculus) under different combination of ketamine and xylazine. The rabbits were divided into three groups. Group A were anaesthetized using a 35 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=5). Group B were anaesthetized using a 40 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3) while group C were anaesthetized using 45 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3). Parameter of observation from left laterolateral view were: 1) the apicobasilar length of the heart (AB), 2) the width of the heart (CD), 3) the distance between the cranial edge of the fifth rib and the caudal edge of the seventh rib perpendicular to the spine (R5-7), and 4) the vertical depth of the toraks (H). Parameter of observation from dorsoventral view were: 1) the length of the heart (L), 2) the width of the heart (W), and 3) the width of the thorax (T). The result from the heart parameters observation that were measured in left laterolateral view and dorsoventral view shows theres no significantly differ among the groups (P > 0.05). The vertebrae heart size (VHS) values obtained from the sum of the length of the long and the short axes on left laterolateral view. The long axes mean values (A) were 4.35±0.26 v and the short axes mean values (B) were 3.59±0.30 v, therefore VHS mean values were 7.94±0.49 v. On the dorsoventral view, the length of the heart mean values (L) were 4.32±0.29 cm, the width of the heart mean values (W) were 3.33±0.26 cm, and the width of the thorax mean values (T) were 5.85±0.30 cm. In normal conditions, the width of the heart should be less than two-thirds the width of the thorax and values obtained of 3.33<3.72 it shows that the heart is in the normal range. The best ratio to calculated the normal heart dimension in the left laterolateral view was compared the long axes with the vertical depth of the thorax, whereas in dorsoventral view, the length of the heart was compared with the width of the heart.
