Judul: Function Of Some Ecosystem Components At Natural Forest And Cacao Agroindustry Sustem At The Margin Of Lore Lindu National Park, Central Sulawesi
Abstrak: Cacao agroforestry is a traditional form of agriculture practiced by the people of Central Sulawesi. These agroforestry systems vary from a simple system, following selective cutting of forest trees, to a more sophisticated planting design. The aims of this research were (1) to determine litterfall dynamics, leaf-litter decomposition, and fine root biomass, (2) to determine active fraction on soil macro-organic matter (SOM) in natural forest and cacao agroforestry systems, and (3) to assess nitrogen resorption and nitrogen use efficiency (N NUE) and implication for cacao establishment. The field studies were conducted in three types of cacao agroforestry systems at the northeastern margin of Lore Lindu National Park (LLNP). Field study sites covering in natural forest (NF) and in three cacao agroforestry systems that is cacao was planted under remaining forest cover (CF1), under planted trees (CF2), and between shade trees Gliricidia sepium (CP). The parameters are nitrogen soil content, fine root biomass, soil macro-organic matter by size and density fractionation, soil surface organic layer by quadrant, litterfall production by litter trap, and rate of decomposition by litter bag, nitrogen use efficiency in cacao plant and ecosystem scale, and nitrogen resorption.

Judul: Perubahan Struktur dan Keanekaragaman Coleoptera pada Sistem Agroforestri Kakao: Pengaruh Umur dan Tataguna Lahan di Daerah Lore Lindu, Sulawesi Tengah
Abstrak: The conversion of forest to agricultural areas is usually associated with loss in biodiversity and its associated ecosystem services. However, some agricultural system such as agroforestry can conserve biodiversity through supporting suitable habitat which are similar to natural condition. The aim of this research is to study community structure of Coleoptera in cacao agroforestry system with emphasize on the effect of age and habitat condition surrounding cacao plantation. Ecological research was conducted in cacao plantation in Central Sulawesi with different type of shade trees i.e remaining forest trees (plot B), planted trees with diverse species (plot C) and planted trees with only 1 or 2 species (plot D). This research monitors the changes of biodiversity that had been conducted in 2003 and resampled in 2009 with the same method in the same plots as well as the same sampling time. In each agroforestry types, four trees were sampled and all the Coleoptera were collected using fogging method. The result of the research showed that the species richness of Coleoptera from three types of agroforestry decreased in composition and structure among the two time period. In 2003, there were 172 species compared to 111 species in 2009. However, there are not significant different between 2003 and 2009 species composition based on analysis of variance using Shannon index. In contrast, similarity analysis using Sorenson index showed that the species composition changed between 2003 and 2009. Age of cacao trees have important role on changing Coleoptera species composition. In addition, habitat condition with natural forest may support Coleoptera diversity in cacao plantation.

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.
