Judul: An eco-physiological study of seasonal crops that form agroforestry in some agroclimate zones on the upstream watershed of Ciliwung
Abstrak: The study consists of three major experiments, namely: the identification and analysis of planting patterns; eco-physiological assessment of seasonal crops; and analysis of land productivity and financial analysis of the agroforestry system in some agro-climate zones.The research objectives were to analyze planting patterns and vegetations that create agroforestry as well as the characteristics of microclimate in some agro-climate zones;examine the eco-physiological characteristics of seasonal crops under different levels of shading; determine the productivity of land and make a financial analysis of agroforestry farming patterns based on the composition and constituent species of agroforestry. The study results of the first stage showed that the land cultivation of the agroforestry system in the climate zone A was quite intensive. The annual crops were cultivated 3-4 times during the planting period one year in the agroforestry system, but 2-3 times in the agro-climate zone C. The combination of agroforestry system with monoculture was more dominant in zone A (60.58%) and B (57.75%) with a simple agroforestry pattern, whereas in zone C (41%) it was with a complex agroforestry pattern. There were seven stands of perennial crops suitable for the agroforestry pattern. The resulted analysis of micro-climate and production found that four types of crops can be planted in the agroforestry system: Lycopersicon esculentum Mill, Capsicum frustescens L, Colocasia esculenta L and Zea mays L. saccharata.In the second experiment, the annual crops from the selection in the first experiment were analyzed for eco-physiological characteristics. It was found that that the most suitable plants grown with the agroforestry pattern were Lycopersicon esculentum Millin zone A; Colocasia esculenta L. in zone A and B; Capsicum frustescens L. in zone B and C; and Zea mays L. saccharata. in zone C. The characteristics that mostly determined the tolerance of the annual crops to the shade were the high interception of solar radiation, the coefficient of light and darkness as well as increased levels of chlorophyll a and b, the reduced ratio of chlorophyll a/b. Some physiological characteristics of plants were found to be related to the efficiency in the capture and use of solar radiation intensity, which include: photosynthesis rate, Photosyntetic Active Radiation(PAR), stomata conductance and CO2 internal. The results of the third-stage experiment showed that the agroforestry systems in three agro-climate zones were technically and economically feasible based on the land productivity and financial analyses. In the agro-climate zone A, that is, the agroforestry system with cinnamon stands the composition and the best annual crops were carrot and tomato. In zone B with albazia stands, the best crops were taro and chili pepper. Zone C consisted of mindi timber stands and sweet corn.

Judul: Manfaat Ekonomi Agroforestri Pada Pola Yang Berbeda (Studi Kasus Petani Sayuran Program Rehabilitasi dan Konservasi Hulu DAS Ciliwung di Desa Sukagalih, Kecamatan Megamendung, Kabupaten Bogor)
Abstrak: The decrease of the environment quality in the regions of upper and lower of Ciliwung’s Watershed Area led to many losses. Conservation and Rehabilitation program for the upper reaches of the Watershed Area is handled by the Bogor Agriculture and Forestry Department which has been started as early as 2011–2016, aimed to repairing the damage by applying agroforestry between Sengon with the veggie plants which is commonly planted by the farming community. Agroforestry patterns were applied in Sukagalih are divided into two patterns, the first patterns is intercropping planting that apply between Sengon and carrot for all seasons, while the second patterns is intercropping planting that apply between Sengon and carrots or beans or caisim with rolling system in one year. The result of the research showed if there is a difference in the number of vegetables plant cultivation for both of patterns. Also, the results of the research showed the value of the highest eligibility obtained by the first pattern with NPV of agroforestry value amounting to Rp 13 416 760, IRR is 38%, and Net B/C is 3.42. Meanwhile, for the second pattern, the value of NPV is obtained about Rp 10 594 816, IRR is 37%, and Net B/C is 3.30. Based on a comparison of the production and revenue for both of agroforestry patterns in Sukagalih, it can be concluded that the value of productivity and average revenue per year of the second pattern greater than the first pattern. The result indicates, intercropping planting that apply by Sengon with many kinds of vegetables are more profitable than intercropping planting that apply by Sengon with just one kind of vegetable which are constant in the span of one year. Total difference between the two patterns of 53.84% or Rp 5 183 568.

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.
