Judul: Substitusi Hara Mineral Organik terhadap Hara Mineral Anorganik untuk Pertumbuhan dan Produksi Tanaman Selada (Lactucca sativa L.) pada Sistem Hidroponik
Abstrak: The increase of organic vegetable demand and unavailablity of organic mineral nutrient for production of lettuce by hydroponic leads an attempt to produce and use organic mineral nutrient that can be used for hydroponic system. The aim of this research was to analyze possibility of substitution of organic mineral nutrient to anorganic mineral nutrient for production of lettuce in hydroponic system. This research was conducted at Hydroponic Amazing Farm green house Karakal Cibedug Bogor from November to December 2007. This research was a factorial experiment with 3 factors that arranged in complete blok design with 3 replication. Those factors were Fertilizers (P1= organic mineral nutrient Nd; P2= anorganic mineral nutrient AB mix); Nutrient Concentration (A1= 1.5 mS-1 ; A2= EC 2.25 mS-1; A3 = EC 3.00 mS-1), and the Frequency of watering ( T1= every 5 minutes and T2 = every 10 minutes). The results showed that Nd organic mineral nutrient with EC 2.25 mS-1 and 3.00 mS-1 and frequency of watering every 5 minutes gave the highest value to all parameters except the plant height plant fresh weight, dry leaves, and the chlorophyl content. This research also showed that Nd organic mineral nutrient with either EC 1.50 mS-1 or EC 2.25 mS-1 could substitute anorganic mineral nutrient.

Judul: Sumber Hara sebagai Pengganti AB mix pada Budidaya Sayuran Daun Secara Hidroponik
Abstrak: Increasing in fertilizer price causing increasing in hydroponic system cost. The objective of the research is to find the best fertilizer that can replace AB mix by examining several sources of nutrients, such as NPK 15:15:15 and NPK 12:14:12by equalizing element N for hydroponic cultivation spinach (Amaranthus L.), pakchoy (Brassica rapa cv. pakchoy) and lettuce (Lactuca sativa L.) in hydroponic. The research was conducted in the Green House, Dramaga Field Unit, University Farm, IPB Dramaga Bogor from February to April 2013. The treatments (AB mix, NPK 15:15:15, NPK 12:14:12) were arranged in randomized completely blok design with 4 replications. Each commodities is separate experiments with 3 treatmens. The results showed that fertilizer treatments gave the highest yield in spinach plants, pakchoy and lettuce in the components yields an average weight/plant, total weight and weight of marketable yield, respectively at 21.65 g, 259.75 g, 235.75 g spinach, 46.06 g, 552.75 g, 465.75 g pakchoy and 25.93 g, 311.15 g lettuce. Based on these results NPK15:15:15 and NPK12:14:12 fertilizer can not replace AB mix as a source of plant nutrients in spinach, pakchoy and hydroponic lettuce.

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.
