Judul: Model pekarangan berbasis praktek  agroforestry sebagai sistem pertanian terpadu
Abstrak: Model pekarangan berbasis praktek agroforesty sebagai sistem pertanian terpadu dibuat untuk mendukung ketahanan pangan pada skala keluarga. Tujuan penelitian ini adalah menginventarisasi, menganalisis pekarangan di Perumahan Dosen Kampus IPB Dramaga. Pengambilan sampel secara acak, berdasarkan ukuran, zonasi, keragaman vertikal dan horizontal untuk membuat model pekarangan 71,4% termasuk klasifikasi pekarangan besar. Zonasi pekarangan yang dimiliki lengkap, yaitu depan, samping kanan atau samping kiri dan belakang. Keragaman vertikal lengkap mulai strata I hingga V, dan 8 keragaman horizontal lengkap. Kolam ikan budidaya ditemukan pada 3 rumah dengan jenis ikan paling banyak adalah ikan lele (Clarias batrachus), namun tidak ditemukan kandang ternak. Pembuatan model pekarangan berdasarkan ukuran, zonasi, keragaman vertikal dan keragaman horizontal. Penggunaan kalender tanam dan penggunaan pola tanam dapat dioptimalkan agar memenuhi fungsi produksi. Pemilihan tanaman tahunan agar pemanenan dapat dilakukan kapan saja. Selain itu, tanaman lokal (indigenous species) dibudidayakan sebagai upaya konservasi agrobiodiversitas pekarangan.

Judul: Struktur, Fungsi dan Dinamika Keanekaragaman Hayati Pertanian Pada Pekarangan di Hulu DAS Kalibekasi, Kabupaten Bogor
Abstrak: Indonesian typical home garden, “pekarangan”, has several ecological potentials of agrobiodiversity. Nevertheless, pekarangan management in Indonesia is facing several problems, such as decreasing plot size, decreasing plant species for production function, but increasing number of ornamental plants for aesthetic function. The objectives of this research are to propose recommendations on agrobiodiversity conservation in pekarangan by analyze the structure, function and spatial dynamic of pekarangan agrobiodiversity in the upper stream of Kalibekasi watershed. This research was conducted in Cimandala, Landeuh and Leuwijambe hamlets which represented the upper part, the middle part and the lower part of the upper stream of Kalibekasi Watershed, respectively, and Sentul City as the urbanized area for comparison. There are 48 samples of pekarangan were observed and analyzed. It was found that pekarangan in the rural area of the upper stream of Kalibekasi watershed have larger space in front yard and one of side yard, but smaller in back yard with multilayer plants. The main function of pekarangan in rural area is a media for production, but in urban area are for micro-climatic amelioration and aesthetic function. The numbers of Margalef index and Shannon-Wiener index show that the upper part has the highest plant diversity. While, the values of Sørensen coefficient indicate that the middle part is the transition place of species similarity of the upper and the lower part. The proposed recommendation is to hold and maintain pekarangan with high diversity of plants and livestocks, which householders get benefit from the product.

Judul: The Leukocyte Profile of Pregnant Friesian Holstein Cows vaccinated with Escherichia coli K99 polivalen vaccine.
Abstrak: The objective of this experiment was to study the leukocyte profile of pregnant cows vaccinated with E.coli K99 polivalen vaccine. Three pregnant Friesian Holsteins cows were used in this experiment. Before the administration of vaccine, the cows were given a series of immunomodulator injection for three days. The vaccinations were administered three times at 8, 6, and 4 weeks before calving. Blood were drawn through jugular vein, first before the administration of vaccines, then weekly until calving. Based on the observation, it can be concluded that the administration of E.coli K99 polivalen vaccine in pregnant cows not affected the leukocyte profile.
