Habitat study and contribution of micro climate and luja (Peristrophe bivalvis merrill) leaf extraction as natural dyes for textile in North Maluku
Abstract
Luja is categorized as fiber dye plant and can potentially be used as plant-based dyes for textile. Plant-based dyes exploration begins with studying plant habitat and which part of plant that produces color, for example its leaf. The objective of the study was to describe contribution of micro climate towards growth and color quality, and total phenol based on position of leaf. The methodology was survey and laboratory testing. Coefficient of determination and SAS 9.3 program were used to analyze the contribution of micro climate and growing media towards plant growth while t-test was used to compare leaf position. The finding showed that luja was grown in Balisoang village, West Halmahera and Bido village in Morotai Island. Temperature, intensity of light and pH of the soil were elements of the micro climate that contributed to growth of luja in Balisoang while intensity of light and pH of the soil were the micro climate elements contributing to the plant growth in Bido. Position of light influenced quality of color and total phenol in both locations. The blades tend to produce brighter color and the shoots produced red color while the leafstalk produced yellow color. In Balisoang, the shoots contained higher phenol than the leafstalk, but the same amount of phenol as the blade. In Bido, all parts of luja leaf had the same amount of phenol.
