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 tingkat perkembangan wilayah dan perubahan penggunaan lahan di Kota Sukabumi
Abstrak: Change in landuse in a city that characterized by dynamic nature and growth is very reasonable. So that, review of land use change is important enough to do in urban area that has rapid changes where generally agricultural land was acquired to meet the needs of land for residential and industrial/service area. Therefore, the purposes of this study are : 1) To Analyze the level of regional development and land use in Sukabumi, 2) To analyze the factors that causes land use changes in Sukabumi City, 3) To analyze land use in Sukabumi City compared with the land capability and the plan of spatial pattern in the Spatial Planning, and 4) To provide strategic policy of direction on land use in Sukabumi City. The result showed that there is only one district that is included in the Hierarchy I region, that is Cikole district. The form of land use in 2002 was dominated by paddy fields (35.13 %), residential (25.24 %) and non-agricultural green space (21.57 %). In the 2007, the dominance of paddy fields and nonagricultural green space are reduced to 34.62 % and 21.09 % accompanied by the increasing of residential to 26.15 %. Based on the results on Hayashi Quantification Type II, the distance to the central government, the distance to arterial roads and the region in Hierarchy II had significantly higher opportunities compared to other explanatory variables to cause land use changes from moor, non-agricultural green space, and paddy fields became the city's infrastructure and residential. From the analysis of land capability, land capability class III is the most land capability class in Sukabumi city (97.8 %). So it can be concluded that the land use in Sukabumi City still approriate with the land capability because land capability class III has a lot of land use options. However, when compared with the plan of spatial pattern in the Spatial Planning Year 2011-2031, there is a significant trend of decreasing area of farmlands from 2.321,43 ha to 375.18 ha and non-agricultural green space from 1.056,37 ha to 485.15 Ha followed by the trend of increasing area of residential from 1.282,48 ha to 2.661,26 ha and city’s infrastructures from 199.15 ha to 1.320,13 ha by the end of year 2031. The priority of strategic policy of direction on land use in Sukabumi City based on SWOT analysis is to establish area zoning with a set of determining and changing criteria of the function of urban space on the implementing of Sukabumi City’s Spatial Planning.

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.
