Judul: Manajemen Lanskap Pekarangan Bagi Penganekaragaman Konsumsi Pangan Keluarga
Abstrak: Pekarangan is characterized by high diversity and stability, good agroecosystems, which should be optimized as a subsistence area daily, specially in fulfilling the nutritional adequacy of the food crops. Therefore, the purpose of this study is to analyze the species, color and nutrients of pekarangan plants, to arrange planting plan with color composition of plants in pekarangan, and to propose crop calendar to support food consumption diversification of the household. Research was carried out in Cikarawang Village, Cihideung Udik Village, and Situ Gede Village. The size of pekarangan is used as a comparison in this study. Each sample can be found a front and back pekarangan, but the left and right side of pekarangan are not always found together in one pekarangan. Plants in strata II and III are the dominant strata that found throughout the size of pekarangan. While the horizontal aspects of diversity, plant fruit trees are the most common (41%). Pekarangan contributed to improving the nutritional quality of plant families, specially from the fruits, vegetables, medicinal plants, and starch crops significantly.

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.
