Judul: Aplikasi dolomit, bahan organik dan pupuk npk pada tanah dicemari Zn: keterkaitan antara sifat kimia tanah dan ketersediaan Zn dengan bobot kering tomat
Abstrak: Urban arable land located near industrial area are vulnerable to heavy metal pollution. One of these heavy metals of concerned is zinc (Zn). In situ inactivation is a prospective remediation methods to be applied on heavy metal polluted-soil of arable land. This technique refers to the use of ameliorants and fertilizers to alter the chen~ical forms of heavy metal pollutants in the environment, thereby decreasing their chemical and biological ability to cause harm. This research was aimed at to evaluate: (1) the effects of amelioration and fertilization at 4 (four) soil Zn-enrichment series on soil chemical properties, the concentration of Zn-bioavailable fraction and dry matter yield of the test plant, and (2) the relationships between soil. chemical properties, concentration of soil Zn-bioavailable fraction and dry matter yield of the test plant. The test plant used in this research was low altitude-dryland tomato. The concentration of soil Znbioavailable fraction was extracted with NH40Ac-EDTA pH 4.65.

Abstrak: Urban arable land located near industrial area are vulnerable to heavy metal pollution. One of these heavy metals of concerned is zinc (Zn). In situ inactivation is a prospective remediation methods to be applied on heavy metal polluted-soil of arable land. This technique refers to the use of ameliorants and fertilizers to alter the chemical forms of heavy metal pollutants in the environment, thereby decreasing their chemical and biological ability to cause harm. In the preceding study, it was evaluated: (1) the effects of amelioration and fertilization at 4 (four) soil Zn enrichment series on the soil chemical properties, including the concentration of bioavailable soil Zn, and the dry matter yield of tomato, and (2) the relationships between the soil chemical properties and the tomato dry matter yield. The present study was aimed at to evaluate: (1) the effects of the same amelioration and fertilization treatment at 4 (four) Zn emiched soil series on Zn, N, P, S, K, Ca and Mg concentration in tomato shoot, (2) the relationships between Zn concentration in tomato shoot with soil chemical properties, including the total and bioavailable soil Zn, and (3) the relationships between Zn with N, P, S, K, Ca and Mg concentration in tomato shoot.

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.
