Judul: Spatial Distribution, Autecology, and Biodiversity of Sagoo (Metroxylon spp.) in Seram Island, Maluku
Abstrak: Sago palm (Metroxylon spp.) is a tropical plant. Its area distribution in Indonesia is the largest in the world, covering 50-60 % of world’s Sago area. It is multifunction plant, however, it is still under utilized. Ecologicaly, sago palm well adapted on fresh water or peat swamp, riverine zone, surrounding water or swamp forests. Unfortunately, there is no any valid information on its area distribution. Moreover, regarding species diversity of Sago is also unclear. Based on the above facts, it is an urgent need to know its ecological aspect, spatial distribution and species diversity. The research was conducted in March to November 2009 at the Seram Island, Maluku. Spatial distribution was developed by Supervised classification of Landsat TM coupled with ground survey to collect Ground Control Points (GCPs) for accuracy assessment. Further field survey was done to collect autecological data. Isozyme analysis was also conducted to identify species diversity. Output supervised classification of Landsat-5TM image in 2007, showed that potential area of sago palm at the Seram Island was 18.239,8 ha. Characteristic of the habitat was distributed in the lowland (elevation less than 250 m asl), flat area, around river, near from beach, and on alluvium soil (sediment). Population structure of sago palm in the nature community follows young growth pattern, in wich rate seedling mortality was about 76,82 %. Regarding the species, M. rumphii Mart. species is the most dominant vegetation which cover 43,3 % of habitat. As adaptation strategy in swampy condition, sago palm form roots which was vertically directed to reach water surface. In sago palm community there was negative interspecific association indicated by Jaccard index less than 0,2. Abiotic component significant effected growth and sago fluor production. The variable that most have significantly effect to growth and sago flour production were micro temperature, micro relative humidity, bulk density, soil acidity, and salinity. The potential clump population at the Seram Island was about 3,2 million clump or approximately of about 1,5 million trunk of trees. M. rumphii Mart. and M. sylvestre Mart. species were the most potential with production capacity of about 566,04 kg starch/trunk and 560,68 kg starch/trunk, respectively. Genetic analysis by isozyme proved that initially known five species of Sago in the Seram Island was actualy only two species, namely Metroxylon rumphii Mart. (concist of M. rumphii Mart., M. sylvestre Mart., M. longispinum Mart, and M. microcanthum Mart.), and Metroxylon sagu Rottb.

Judul: Identification of Sago Palm (Metroxylon spp.) Accession in Mamuju sub-District, Mamuju District, West Sulawesi Province
Abstrak: Sagu (Metroxylon spp.) merupakan tumbuhan yang berasal dari Indonesia, sekitar 85% sagu dunia terletak di Indonesia. Sagu memiliki potensi yang tinggi, khususnya sebagai tumbuhan pencegah kelaparan. Penelitian ini bertujuan mengidentifikasi aksesi sagu berdasarkan karakter morfologi, produksi, dan genetik di Kecamatan Mamuju, serta kekerabatan sagu di Provinsi Sulawesi Barat menggunakan metode RAPD. Analisis tutupan lahan sagu menggunakan metode pengindraan jauh juga dilakukan untuk mengetahui potensi produksi Kabupaten Mamuju. Terdapat 3 jenis sagu yang terdiri atas 2 jenis tidak berduri, yaitu Kasimpo, dan Kapas, serta 1 jenis berduri yakni Ruwi. Aksesi Kapas menjadi aksesi dengan produksi pati kering tertinggi, dapat mencapai 717,90 kg batang-1. Produktivitas sagu di Kecamatan Mamuju 15,03 ton pati kering ha-1 tahun-1. Produksi pati kering memiliki korelasi terbesar dengan panjang batang (0,872), jumlah daun (0,703), dan diameter batang (0,575). Hubungan kekerabatan (RAPD) berbagai aksesi di Provinsi Sulawesi Barat tidak begitu jauh, dengan nilai Kf <80%. Berdasarkan hasil pengindraan jauh berupa interpretasi citra satelit Pléiades-1A/-B, diketahui luas sagu di kabupaten Mamuju yaitu 252,74 ha. Tutupan lahan sagu terluas terletak di Kecamatan Kalukku yakni 95,27 ha dan tersempit di Kecamatan Kalumpang yaitu 0,91 ha. Peta yang dihasilkan memiliki akurasi sebesar 81,58%., Sago (Metroxylon spp.) is an original plant from Indonesia, about 85% of the world’s sago grown in Indonesia. Sago has a high potential, especially as a prevent hunger plant. The research aims to identify sago accession based on morphology, production and genetic in Mamuju sub-District, and the sago relationship in West Sulawesi Province using RAPD method. Sago land cover analysis using remote sensing method was used to estimate spotential sago production in Mamuju District. There were 3 accession observed, i.e. 2 type non spiny, Kasimpo and Kapas, and 1 type spiny it is Ruwi. Kapas is the hights production dry starch accession, it is reaching 717,90 kg trunk-1. Sago productivity in Mamuju sub-District is 15,03 tons dry starch ha-1 year-1. Dry starch production had the hights correlation with trunk length (0,872), number of leaves (0,703), and trunk diameter (0,575). Relationship (RAPD) various accession sago in West Sulawesi Province was not too far, Kf value <80%. Based on remote sensing with satellite Pléiades-1A/-B imagery interpretation, the sago area in Mamuju District estimated 252,74 ha. The largest sago area is in Kalukku sub-District, which is 95.27 ha and the narrowest is in Kalumpang sub-District, which is 0.91 ha. The map has 81.58% of overall accuracy.

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.
