摘要

Waterleaf (Talinum triangulare (Jacq.) Willd has long been eaten in Indonesia as vegetable and the main parts consumed are leaves and young shoots. Waterleaf is sticky presumably due to its pectin content which is associated to dietary fiber. The dietary fiber which was analyzed in the present study was influenced by cultivation practices. The aim of this research was to study the effect of organic and conventional fertilization as well as the seasonal changes to the level of TDF (total dietary fiber), IDF (insoluble dietary fiber), SDF (soluble dietary fiber), and pectic substances in waterleaf. This research was conducted in four phases: sample cultivation, sample preparation, chemical analysis, and data analysis. This research used five samples cultivated with 5 different compositions of organic fertilizers and vice versa for conventional fertilizers. The cultivation was done in the experimental field of University Farm, Bogor, Indonesia during rainy season and dry season. Samples were harvested 8 weeks after planted, dried using drying oven for 17 hours at 60°C, ground and filtered to 40 mesh;and kept at -10°C until analysis. The overall result showed that the conventional samples contain higher dietary fiber than the organically fertilized samples, except the pectic substances of plant in dry season. Although its IDF content is higher than the SDF, the SDF content of waterleaf is relatively high compared to other vegetables, especially in dry season.
