Judul: Dampak Penambangan Bauksit pada Lahan Hutan di Pulau Kas Kepulauan Riau
Abstrak: Kas Island is one of the small island in Karimun Regency which became the location of bauxite mining. Mining activities can cause massive damage and it is not impossible to drown the island. The former mining areas has low soil fertility. The objectives of this study were to analyze changes in physical and chemical properties of soil in Kas Island, Karimun Regency, Riau Islands Province before and after become a bauxite mining. This study used data from the laboratory analysis of soil physical and chemical properties obtained from the agency team of Environment, Karimun Regency. Laboratory test data of physical and chemical properties of the soil, descriptively and statistically analyzed using T test at 95% confidence interval. Results of the analysis showed that the mining activities cause a change in the physical properties of the soil that increase the value of the bulk density variable and a decrease in porosity variable, pore drainage, available water and permeability. While on soil chemical properties showed increase at variable pH, Ca, Mg, and K and decreased content of the variable-organic C, total N, P bray, and Na. The results of data analysis showed statistically significant differences in all variables of soil physical properties that analyzed. Soil chemical properties that significantly different are on the variables: organic-C, total N and P bray. Meanwhile the variable of soil chemical properties that not significantly different are : pH, Ca, Mg, K, and Na.

Judul: Dampak Pertambangan Batu Granit terhadap Sifat Fisik, Sifat Kimia, dan Sifat Biologi Tanah di Areal Hutan Lindung PT. Karimun Granit Kabupaten Karimun Propinsi Kepulauan Riau
Abstrak: Introduction. Indonesia have variated potency of nature resources that indigenous to forest. Besides management of forest, there is other activity that goes on in forest area that is mining activity. Mining Activity generaly conducted in nature forest, and even protected forest. Mining Activity of course can destroy forest ecosystem that opened for made areal mining. Mining Activity cause vegetation and land damage that affect erosion and sedimentation. Mining also can cause loss of land fertility at ex areal mine. In consequence, its needed research about the impact of mining . Specifically for granite mining that conducted PT. Karimun Granite in Sub-province Karimun, Province Kepulauan Riau, that reported has caused various of landscape and land damage in the mining areal. Materials and Method. This Research uses data of physical characteristic analysis, chemistry and biology of protected forest area land PT. Karimun Granit Sub-province Karimun, Province Kepulauan Riau. Research Method as used in this research is by purposive sampling, that location has been determined by Tim KementrianLingkungan Hidup. Data of physical analysis, chemistry and biology characteristic are compared to every location to analize the level of change at each of land characteristic value. Analysis of land characteristic is conducted to know the characteristic of physical, chemistry, and land biology at research location. Analysis of Variance (ANOVA) by F test to variable perceived, conducted to know physical denaturing, chemistry and land biology after activity of granite mining. If f-count reach > F tables (value of reality opportunity < 0.05) or granite mining has an effect on reality, then conducted test continues to compare the middle value treatment. The test continues that used is Tukey test. Result and Discussion. Base value of analysis result characteristic of physical, chemistry, and land biology is known that at the three of location that is nature forest, dig land, and erotion land value each characteristic of land experiences of change either degradation or improvement. Then base testing result by F test, characteristic of land physical are not influenced manifestly by granite mining. Whereas for characteristic of chemistry and biology of some of which land is influenced manifestly by granite mining that is C-Organic, N-total, Mg, Na, KTK, Mn, and totalize mikroorganisme land. Result continues Tukey test for land characteristics referred as indicate that value at dig land and erotion land differ reality by value at nature forest. Conclusion. Activity of granite mining causes change the physical characteristic of land, that shown by the increase of bulk density, and degradation of land porosity, water availabilty, and permeability. In other hand, activity of granite mining causes change at characteristic of land chemistry that shown by increasing of pH, Fe, and Zn and degradation of C-organic content, KTK, N-total, P-Bray, K, Ca, Mg, Na. And then, activity of granite mining causes change at characteristic of land biology that is shown by increase of fungi land, totalize solute P bacterium, and totalize land respiration, and degradation of land mikroorganisme.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
