Judul: Identifikasi pola dan proses perubahan pengunaan lahan menggunakan analisis fragmentasi di wilayah peri-urban Kota Makassar Provinsi Sulawesi Selatan
Abstrak: Peri-urban area hosts resources and environment to support essential ecosystem functions for urban settlements. Growing number of urban residents trigger increasing need of land use conversion for settlements, industries, and businesses. Generally, population growth rate in peri-urban regions is higher than on urban, including in Makassar hading to a land use change vast and dynamic. Pattern and process of land use change in Peri-urban area of Makassar city were analyzed using transition and fragmentation analysis where as actor of the land use change was presented based on semi structured interview. The results of transition matrix analysis presented information regarding land use change pattern. Makassar experienced rapid land use change, for example from rice fields, ponds, and swamps were converted to upland crops and eventually converted to settlements, industries, and businesses. Rice fields to settlements or industries conversion process occurred through land draining and land filling. Land use change was usually preceded by transfer of land ownership. It frequently happened due to government policy and socio-economic condition of the society. Fragmentation analyses of land use were conducted on land use for settlements, industries, and businesses as the major land use pattern in urban areas. The results indicated that Peri-urban of Makassar were very dynamic, not only in spatial perspective but also in terms of complex processes. Fragmentation types such as core, edge, and patch contributed to urban sprawl. Fragmentation process of land use was characterized by perforated type. The decline of patch value could be interpreted as an indication of land agglomeration. Land use change occurred in Peri-urban of Makassar was done by landowners in a variety of ethnicity/race and education levels. It should be mentioned here that construction of public services by the government also contributed to this land use change and its fragmentation.

Judul: Analisis Spasial Perubahan Penggunaan dan Fragmentasi Lahan di Wilayah Pinggiran Jakarta
Abstrak: Human activities will affect on an increasing of land-use change and landscape structure associated with the level of land fragmentation. This research aims to assess the dynamics of land use change and the fragmentation level of agricultural land and built-up land in peri urban of Jakarta. The existence of paddy fields, excavation C and forests accelerate the dynamics of land use change significantly in the study area. The result of agricultural land fragmentation analysis shows that districts which were closer to large cities tend to have lower NumP parameter, which indicates that built-up polygon has united into a single compact polygon. Areas affected by major cities i.e Jakarta and Depok has small TE and NumP, while MPS value was only influenced by the proximity to Depok. The analysis of built-up land fragmentation shows that the fringe of big city has a smaller rate of NumP and TE and more significant decrease of MPS compared to region farther from the big city. NumP, TE and MPS can be used to determine the rate of development and the pattern of development in the region. Areas affected by large cities are likely to have a stable lower rate of development with a homogeneous built-up land, whereas the distant regions to big cities are possibly to have a complex and greater rate of development with a heterogeneous built-up land. The results of multiple regression analysis for the village and neighborhood (RT) scale show that the main variables influencing agricultural land fragmentation are land ownership and accessibility, while factors affecting builtup land fragmentation are land ownership, land prices and accessibility.

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.
