Arrangement of blocks and vegetation of urban forest based on land cover and soil properties to increase the functions of recreation, soil and water conservation in Pondok Labu, South Jakarta

Abstract

Urban forest constitutes a part of an urban ecosystem which has multifunctions. The urban forest of Pondok Labu has ever undergone erosion and landslide which reduced its function. The objective of this research was to study the arrangement of the Pondok Labu Urban Forest based on land cover and soil properties. The collection and processing of data comprised among others the general condition of the area, classification of vegetation density based on NDVI, measurement of leaf area index using technique of hemispherical photograph and software Hemiview 2.1, measurement of throughfall, vegetation analysis and soil erodibility. Afterwards, the determination of the block position and function, and vegetation arrangement were conducted by descriptive and qualitative analysis. There were two blocks developed, i.e.: intensive block and non-intensive block. The intensive block was plotted in the land which has not undergone landslide as visitor activity center. Non-intensive block is a rehabilitation block on the post landslide area. Arrangement of the vegetation is adjusted with the site condition and vegetation function. The edge parts function as shading plants, wind break and noise reduction. The middle part contains plants producing flowers and fruits. The inner part contains plants producing fruits to attract birds.
