PEMANFAATAN TUMBUHAN DALAM PROSES PEWARNAAN KAIN TENUN IKAT DI PULAU NDAO, DESA NDAO NUSE, KABUPATEN ROTE NDAO

ABSTRACT This study aims to determine the types of natural coloring plants, organs plant or parts used, the processing to the colors produced from plants organs used in the process of coloring woven cloth on Ndao Island, Ndao Nuse Village, Ndao Nuse sub-district, Rote Ndao Regency. The method used is a qualitative descriptive method. The technique used in this study is direct observation techniques in the field and semi-structured interviews. Semi-structured interviews are interview processes that use interview guides derived from the development of topics and ask questions to ikat weaving craftsmen, the aim is to explore and obtain information related to the data needed. Based on the results of research in Ndao Nuse Village, Ndao Nuse sub-district, Rote Ndao Regency, found 5 types of natural coloring plants that are utilized by the Ndao Nuse community in the process of coloring woven cloth, namely tarum (Indigofera tinctoria L) producing black, turmeric rhizome (Curcuma domestica L) producing yellow, legundi (Vitex trifolia L) produces a light yellow color, kedondong fence (Lannea nigratana) produces a brown color, the green color is produced red distance (Jatrhopa gossiphofolia). Parts or organs of plants used are leaves, rhizomes and bark. The process of processing plant parts or organs that are used to produce color includes collision, boiling, and soaking. In addition to the 5 types of plants that are used as basic dyes there are also plants and other additives used in the coloring process are lime, whiting, and alum. The benefits of this additional material are as a color enhancer so that the color produced does not fade easily. Most of the plants that have potential as natural dyes for connective weaving have been cultivated. Plants that are cultivated are tarum, turmeric, and kedondong fence. Keywords: Weaving, Natural Staining Plants ABSTRACTThis study aims to determine the types of natural coloring plants, organs plant or parts used, the processing to the colors produced from plants organs used in the process of coloring woven cloth on Ndao Island, Ndao Nuse Village, Ndao Nuse sub-district, Rote Ndao Regency.

“SUBSTITUSI TEPUNG Cucurbita moschata (Duch.) Poir TERHADAP KADAR β-KAROTEN DAN DAYA TERIMA CAKE LABU KUNING”

ABSTRACTPumpkin (Cucurbita moschata (Duch.) Poir ) is one of the vegetables that is rich in β-carotene as a precursor of vitamin A and has a fairly high carbohydrate content. Pumpkin processing can be done to produce various kinds of products, one of which is cake. Cake is a baked dough and liquid dough made from flour, sugar, salt, ingredients, shortening, milk, eggs, and aroma enhancer. This study aims to determine the levels of β-carotene contained in pumpkin cake and to determine the acceptability of β-carotene in pumpkin cake. This research is an experimental research. The experimental design used was Completely Randomized Design (CRD) with 1 control 4 treatments and each treatment was repeated 3 times. The research phase consisted of making flour and making cake. Data collection methods include organoleptic tests and β-carotene tests. Data were analyzed using analysis of variance / ANOVA to determine differences in quality, and if there is an influence then proceed with the Tukey test. Organoleptic test results show that the best treatment of pumpkin cake in terms of color is A1 with a value of 3.88, in terms of aroma namely A0 with a value of 3.92, in terms of texture is A0 with a value of 4.28 and in terms of taste is A0 with value of 4.16. As for the β-carotene test, the treatment of pumpkin cake with the highest β-carotene content was found in A4 with an average of 0.262 and the lowest level was in A0 with an average of 0.018. Based on research data, pumpkin flour is worthy of being used as an alternative source of flour because the resulting cake meets SNI quality standards both in terms of color, taste, aroma, texture and β-carotene content.Keywords : Cake, Pumpkin, β-Carotene, Organoleptic
