Abstrak: One type of forest types which has potential in carbon sequestration and storage is peat swamp forest. The purpose of this study was to calculate the potential and distribution of carbon mass in the peat swamp forest area of IUPHHK-HA PT. Diamond Raya Timber, Dumai, Riau Province. Estimation potential total of carbon mass in forests 90 956 ha area are 8 055 234 tons. Distribution of carbon mass in the peat forests of this area are classified into four classes, consist of very high, high, medium, and low. Very high carbon mass class is over 272.54 ton ha-1, high carbon mass class is between 177.80 ton ha-1 and 272.53 ton ha-1, medium carbon mass class is between 118.82 ton ha-1 and 177.79 ton ha-1, and low carbon mass class is less than 118.82 ton ha-1. The distribution of the carbon mass potential according to the carbon mass classes are as follows in high class area 6 200 ha with carbon mass stock of 1 302 097 tons, in medium class area 18 100 ha with carbon mass stock of 2 550 718 tons, in low class area 60 400 ha with carbon mass stock of 4 202 419 tons.

Judul: Pendugaan Potensi Biomassa Hutan di Areal IUPHHK-HA PT. Diamond Raya Timber, Dumai, Provinsi Riau
Abstrak: Forest has an important role in absorbing CO2 which used in the process of photosynthesis to produce O2 and most of the produced energy is in the form of biomass. One type of forest that has biomass storage is peat swamp forest. The purpose of this study is to calculate the potential and the distribution of biomass in the area of peat swamp forest. The results of the study showed that forest biomass on 90 956 ha area are 17 297 664 tons. Distribution of natural peat forest biomass in this area is classified into four classes, they are low grade that has biomass potential less than 215.56 tons/ha, medium grade that has biomass potential between 215.56 to 319.86 tons/ha, high grade that has biomass potential between 319.86 to 486.53 tons/ha, and very high grade that has biomass potential more than 486.53 tons/ha. The spread of peat swamp forest consist of in low grade peat 61 100 ha with 10 387 000 tons biomass, in medium grade 17 600 ha with 4 595 888 tons biomass, in high grade 5 800 ha with 2 195 880 tons biomass and very high grade 200 ha with 118 896 tons 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.
