Judul: Developing The Green Space Based On The Surface Temperature Distribution and Temperature Humidity Index of Palembang City
Abstrak: Palembang is the provincial capital of South Sumatra. The Municipality are experiencing increase of population and fast development in many sectors. This resulted in the increase of build up areas and reduce green open space (green space). The condition lead to micro-climate changes, such as increasing air temperature and decreasing humidity that worsen the comfort ability of living . The study aims to: (1) identify the spatial distribution of surface temperature in some types of land cover, NDVI (Normalized Difference Vegetation Index) and its relation to the green open spaces, (2) Mapping of Temperature Humidity Index (THI) or comfort index in the region of Palembang and (3) Development of green space based on the distribution of surface temperature, air humidity, THI, and urban planning. The study was conducted in the city of Palembang. Materials used in this research are a Landsat 7 ETM (Path 124 Row 062) dated May 10, 2001 and August 23, 2010 and the administrative boundary map of Palembang. Processing of Landsat 7 ETM image data using a set of computers equipped with software ArcGIS 9.3 and Erdas Imagine 9.1, which includes the layer stack, geometric correction, cropping the image, image classification, and test accuracy. Estimation of surface temperature was conducted by using band 6. Furthermore, estimation results are used to estimate temperature and air humidity comfort index (THI) in the city of Palembang. In addition, the determination of vegetation land cover was also done using NDVI. NDVI values were used to determine the relationship between surface temperature and land cover. Palembang surface temperature ranges from 27 ° C to 39 ° C. Surface temperature on the green space ranges from 28 ° C to 32 ° C, while the surface temperature in the build up area more than 33 ° C. There was an increase in surface temperature from 2001 until 2010. The changes were associated with reduction of green space area. RTH can be predicted with NDVI values. NDVI values greater than 0 and less than 1 was vegetation. Surface temperature has the opposite relationship with NDVI. The greater surface temperature the lower the NDVI value and vice versa. Palembang City was entirely classified into uncomfortable class in 2001 and 2010, since the city located on THI values over 26. Development of green space in the city of Palembang was divided into three type of activities, namely, at housing areas, suburbs and downtown areas. Development of green space at settlements in the form of green yard, and its surface temperature ranges from 30 ° C-34 ° C, humidity 60% -70% and average THI ranged 27-28. In the suburbs, can be developed green space in the form of city parks and urban forest, the surface temperature of 29 ° C-34 ° C, humidity 60% -80%, and THI averaging around 26-27. In the downtown area can be developed in the form of roof garden green space and green be, the surface temperature above 33 ° C, humidity 40% -60% and the average ranged THI> 31,

Judul: Distribusi Spasial Suhu Permukaan dan Kecukupan Ruang Terbuka Hijau di Kota Semarang
Abstrak: Semarang is one of cities that become center of public activity which is always developing in many aspects such as settlement, , roads, industries and other infrastructures. Unfortunately, The development seems to ignore environmental sustainability, in which large of green open space are converted into other land uses. The conversion will lead micro climate changes resulted in Urban Heat Island and green house effect. Those phenomenon can be observed by utilizing Geographic Information System and remote sensing. The objectives of the research are as follows : (1) land cover type identification and surface thermal of spatial distribution, , (2) the relationship between surface thermal with Green Space capacity, open land and built areas. (3) the relationship between surface thermal with Normalized Difference Vegetation Index (NDVI), through interpretation and landsat Imaginery 7 ETM. The research area situated at in Semarang City and data used were Landsat Imaginery 7ETM path/row 120/065 acquiring on April 2001 and June 2006. Landsat imagery were analyzed using an Arc View 3.2 and ERDAS Imagine 8.5 software. Surface temperature were estimated using band 6. Those analysis were aimed to identify relationship between surface thermal with Green Space, the open land, built area and NDVI. Semarang city with 38.721.70 Ha are dominated by land cover, such as built area 27.52% on year 2001 and 35,58% in 2006. The biggest land cover changes happened on built area and with advancing is 8.06%. Thermal Surface distribution were found ranges from <20 oC - ≥34 oC. The area which have thermal surface value of ≥34 oC was expanded from 16.80 % in 2001 to 25.68% in 2006. However, green space capacity areal are still covering 30%, inline with proportion based on UU. No.26 on 2007 about areal governance. The relationship between surface thermal with Green Space and other land uses were identified. It showed that surface temperature of open space area is lower than other landuses such as bare land and settlement. Moreover, It analysis result showed that surface temperature will infllence by NDVI, in which the surface temperature will increase by the lowering NDVI and vice versa.

Judul: Profil Eritrosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Afoxolaner banyak digunakan untuk mengobati dan mencegah infestasi caplak pada anjing. Senyawa tersebut memiliki efektivitas yang tinggi dan mampu mencegah reinfestasi sebulan sejak diberikan. Hingga saat ini belum diketahui efek afoxolaner terhadap profil eritrosit anjing. Afoxolaner diberikan kepada enam anjing beagle (8-12 bulan) yang secara klinis tidak terinfestasi caplak. Anjing dibagi menjadi dua kelompok perlakuan yang berbeda. Kelompok 1 diberikan sediaan afoxolaner sebanyak satu kali dosis anjuran sementara kelompok 2 diberikan lima kali dosis anjuran. Pemberian sediaan afoxolaner dilakukan sebulan sekali sebanyak tiga kali pengulangan dengan jarak antar pemberian satu bulan. Sampel darah diuji menggunakan hematology analyzer MEK-6450 dan data dianalisis menggunakan perangkat lunak SPSS 16.0. Hasil yang didapat menunjukkan bahwa secara statistik tidak ada perubahan signifikan antara profil eritrosit anjing beagle sebelum dan sesudah pemberian sediaan afoxolaner. Disimpulkan bahwa pemberian sediaan afoxolaner lima kali dosis anjuran secara oral tidak memengaruhi profil eritrosit anjing beagle.
