Abstract

Nata de coco is one of the functional food made from coconut milk which is processed through fermentation by using acetic acid bacteria, Acetobacter xylinum. It convert glucose into cellulose in coconut wate medium. Undigested cellulose consumed in the body that it will benefit to the human digestive system. The formation of nata requires a source of C, H, N, and minerals. Coconut water have already contains most of the nutrients it needs, but still needs to be enriched with other nutrient sources added. As a source of sugar can be added sucrose, glucose, fructose, starchs and flour maezena. This study aims to determine the physical properties of nata with different carbon sources. The addition of fructose would produce nata de coco with the most optimum yield at 0.755 g nata / ml coconut water with 8.41 mm thickness, 3.92 g wet weight and dry weight of 0.47 grams. However, nata produced has a less chewy texture with 87.56% moisture content. Key-word: Nata de coco, source of carbon, coconut water, Acetobacter xylinum

Abstract

Studies on Rukun Warga (Citizens' Association) have not yet been viewed as a street-level leadership practice. This article aims to examine Rukun Warga leadership in public service through the Street Level Leadership theoretical framework. This framework is used to understand the relational leadership practices of RW (Neighborhood Unit) officials in carrying out public service activities in their neighborhoods. Using ethnographic methods with unstructured interviews and non-participant observation in three Rukun Warga areas in the Surabaya City area, this study examines the daily practices of activating administrative knowledge and decision-making discretion, and establishing a supportive community of residents. This study concludes the importance of relational leadership through administrative knowledge, community harmony as an output of public service.
