Judul: Keragaan Rotan di Areal Konservasi Ex-Situ Hutan Pendidikan Gunung Walat Sukabumi, Jawa Barat
Abstrak: Ex-situ conservation stands has been established in Gunung Walat University Forest (GWUF) since 2005. However, the performance of rattan has never been evaluated. The objectives of the research were i) to review the correct species name of rattan and ii) to assess the growth variation of rattan with respect to shade trees, environmental factors (light and pest). The growth performance was observed through assessment of species composition and structure of the stand including distribution of diameter and length, biomass estimation and environmental effects (light and pest). The results showed that i) there were 3 (three) rattan species planted in the ex-situ conservation stand, namely Calamus manan, Daemonorops melanochaetes and Daemonorops rubra, ii) The composition and structure of the stands were still dominated by the shade trees. Rattan was found predominantly at strata C (4–20 m) and strata D (1–4 m). The normal distribution was observed only on diameter and length of C.manan and D.melanochaetes, respectively. The highest biomass was observed in D. rubra that was estimated as much as 26.6 tons/ha. The light had significant effect on D.rubra diameter only. On the other hand, pest had no significant effect on rattan growth variables.

Judul: Growth and Wood Rigidity Assessment of Standing Tree Meranti (Shorea spp.) in the Gunung Walat Educational Forest, Sukabumi.
Abstrak: Meranti (Shorea spp.) adalah kelompok kayu yang bernilai ekonomi tinggi, dengan tingkat eksploitasi yang terus terjadi di hutan alam, sehingga diperlukan suatu tindakan konservasi. Hutan Pendidikan Gunung Walat (HPGW) telah melakukan upaya konservasi jenis Shorea spp. secara ex-situ, namun kegiatan evaluasi belum dilakukan secara berkala. Evaluasi pertumbuhan termasuk kesehatannya serta faktor-faktor yang terkait perlu dilakukan. Tujuan dari penelitian ini adalah untuk i) mendapatkan data pertumbuhan pohon, ii) mengetahui kesehatan tegakan, iii) menduga kandungan karbon organik, dan iv) menganalisa hubungan karakteristik kekakuan kayu berdiri berdasarkan metode non-destruktif dengan pertumbuhan. Hasil penelitian ini diharapkan dapat memberikan informasi dalam status pertumbuhan tanaman dan kekuatan kayu Shorea spp. yang berada di HPGW., Meranti (Shorea spp.) is known as important group of timber species in Indonesia that belongs to the Diptercarpaceae family. Due to its high commercial value, exploitation of meranti was very high leading to a significant reduction of natural population size as well as urgent call for conservation action outside its natural habitats. Therefore, a demonstration plot for ex situ conservation stand of five meranti species, namely Shorea palembanica, Shorea mecistopteryx, Shorea stenoptera, Shorea pinanga, and Shorea leprosula, was planned and established in 2004 at Gunung Walat Educational Forest (GWEF), Sukabumi. However, this conservation stand has not been yet thoroughly evaluated. Research through field assessment was carried out in the stand with objectives as follows: i) to determine tree growth, ii) to assess tree health condition, iii) to calculate the potential of carbon uptake and iv) to estimate the wood quality of standing trees based on a non-destructive method.

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.
