Judul: Soil development of mine Tailings in ModADA PTFI : reclamation and natural sucession aspect
Abstrak: Tailings are residue of mining material after separation of valuable substances such as copper, gold and silver elements. Separation of these elements involves crushing of parent material to become fine particles and separation of the precious elements by flotation technique. Total amount of tailings produc ed by PT Freeport Indonesia are about 230.000 tons/day. These tailings are transported and deposited in the lowlands of Timika, Papua and confined in the two levees i.e East Levee and West Levee called as ModADA (Modified Ajkwa Deposition Area). The research had been done in ModADA, the property of PTFI in Timika, Papua from March to November 2005.

Judul: Characterization and Soil Development on Reclaimed Coal Mine Land at PT Kaltim Prima Coal
Abstrak: Mining activities are part of economic development activities that utilize natural resources and are expected to guarantee the future life. Issues that will arise as a result of mining activity which may result in less negative impact on the environment are in the form of decreased soil productivity, soil compaction, erosion and sedimentation, soil movement/ soil erosion, decrease in biodiversity of flora and fauna as well as changes in microclimate. Reclamation is the end of mining activities are expected to return the land to its original state. The ultimate objective of reclamation is to improve the Quarry to the condition safe, stable and not easily eroded so that it can be recovered. To see how far the influence of the reclamation of soil properties and its development, it is necessary to observe and study in detail the characterization of soil development on reclaimed land, whether it is possible that significant changes to the development of soil formation on land reclamation to the aspect physical, chemical and biological soil properties. The results indicate that the reclamation and increased of age affects the development of land reclamation seen from morphological, physical, chemical, and biological soil properties. Increased age of reclaimed coal mine land causes changes in the morphological soil property, especially on the top layer. The most affected changes of morphological soil properties by increasing age is the color of the land reclamation and the boundaries between layers, especially on the top soil layer due to the effect of adding organic matter. Increased age in the reclaimed land causes changes of soil physical properties, ie increased permeability and soil aggregate stability, but not affect bulk density. Increased age affects the chemical properties of soil reclamation, it is seen by an increase in C-organic, N-total, exchangables Ca and Mg content on topsoil. Changes of the biological soil properties occur until reclaimed coal mine land was 5 years old which in 5th years has the highest of individuals density, diversity indices and biomass.

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.
