Judul: Hubungan Ruang Terbuka Hijau (RTH) dengan Temperature Humidity Index (THI) Kota Depok
Abstrak: Urban green space is an elongated area /point and /or clustered, the use of which is more open, a place to grow plants, whether grown naturally or are deliberately planted. Urban green space has a great benefit to the environment of the city, including the benefits of climatological, ecological, aesthetic, and tourism. Depok City is a strategic area for the capital city of Jakarta because of Depok has a function as a buffer zone in southern Jakarta. This study attemps to estimate values of air temperatures using Landsat data, functional relationship between air temperature and urban green space, and also relationship between urban green space and temperature humidity index in Depok City. Air temperature are derived from Landsat data using energy balance method, while urban green space are classified by using unsupervised method. Estimation air temperature of Depok City in 2001, 2002, 2004, 2005, and 2006 are 24.5 oC, 25.5 oC, 26 oC, 26 oC, and 30 oC, while urban green space are 63%, 57%, 55%, 55%, and 42%. Functional relationship between air temperature and urban green space for the study area best represented by a non-linier equation. Temperature humidity index values of depok city in 2001, 2002, 2004, 2005, and 2006 are 25.oC, 25 oC, 26 oC, 26 oC, and 27 oC.

Judul: Relationship Between Urban Green Space and Surface Temperature By Using Image LANDSAT TM/ETM+ (Region : DKI Jakarta)
Abstrak: Urban Green Space (RTH) is regions covered by different types of vegetation in order to support direct and indirect benefits for the comfort and well-being. Jakarta has a rapid land cover changes every year, and the increased activity of the city brought an indirect impact on climate in the component elements. RTH reduction affects climate elements, one of which is surface temperature. Surface temperature is strongly influenced by the conditions of closing its land because of the nature of emissivity and thermal conductivity. This study examines the relationship between green space and the surface temperature using remote sensing techniques of LANDSAT satellite in 1992, 1997, 1999, 2000, 2001, 2004, and 2006. The technique used to determine the value of green space that is a supervised classification of various types of closure land use channel 5, 4, 2 (RGB), and to determine the surface temperature is used channel 6 (thermal) by processing the spectral radiance values and the digital number. The area of green space in a row in 1992, 1997, 1999, 2000, 2001, 2004, and 2006, was 42.2%, 32.1%, 29.7%, 27.4%, 26.3%, 22.5%, and 19.3%. While the surface temperature values obtained by the RTB 29oC-42oC, 27oC-30oC RTH, and a body of water 17-26oC. Surface temperature is strongly influenced by the conditions of closing its land, so the reduction in green space contributes to an increase in surface temperature.

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.
