In 2017, the researcher discovered taka germplasm in Thousand Islands .Taka conservation research and variations in taka characters need to be done to preserve taka in an effort to make taka as tuber as well as an alternative food .The previous results showed that Thousand Islands were one of the suitable locations for taka growth. Besides conducting research on character variations, a proximate analysis of taka from the Thousand Islands was also carried out. This research used survey method with the analysis of vegetation in the field and the proximate analysis in the laboratory. The research was conducted from April to November 2017.Erlinawati et al (2018) stated that kecondang plants / taka were used in several regions in Indonesia as alternative food if there were large waves and difficult transportation to the city. This study aimed to determine. variational characterization in plant growth , plant ecological conditions and analyze the proximate content of kecondang / taka tuber from Thousand Islands. Kecondang plants / taka (Taka leontopetaloides (L.) Kuntze is a bulbous terna plant that reaches up to 2m in height. (Erlinawati et al. noted that taka umbulbulb areflat,wide, thinskinned, light brown when young and gray, dark brown when old. The inside is milky white, it grows below the soil surface to a depth of 50 cm. In its growththe first formed tubers are usually small and change into larger ones. The leaves consist of 1-3 strands, in the form of a broad breech of egg breed, soaring round, boned, runny, greenish white (green variant), or purplish (black variant). Each segment is pinned pinnate, its lobes are broken. The stems are perforated, leafy , vertical grooved, blackish or purplish (black variant). The inflorescence has flowers 1,2,5 and 20 -40. The flowers are protected by outer and inner bandages, green or yellowish, purplish green, rhombic, breech-faded egg, filiform leaf-shaped leaves like sticks, green in purple. Flowers do not open perfectly, arranged in (3 + 3) in which the inner part of the egg is broadly colored purplish green. As for the outer part, it forms a melanin purplish green,black), or white with white glands (green variant shape of the tuber can expand up to10 cm. This study aims to determine variational characterizations in plant growth , ecological plant conditions and analysis of proximate content of kecondang tuber / taka from Seribu Islands. for the community nutrition. Presently, tubers that are consumed by the community, are cassava and sweet potatoes. Taka (Taka leontopetaloides L. Kuntze), which Javanese people call kecondang and while among the Madureseit is better known as lorkong and o'to as sources of carbohydrates.More information on its .More information on its local use however has yet to be discovered. Taka leontopetaloides in Thousand Islands are known as "Tongkat Nenek Lampir" which in ancient times hadalso been consumed before the presence of wheat flour which were imported. which in ancient times hadalso been consumed before the presence of wheat flour which were imported. The proximate analysis shows that taka leontopetaloides have sufficient nutrient substances of carbohydrates and minerals. Taka leaves are used as vegetables, while its leaf and flower stalks produce fibers that can be used to make hats and ropes. Taka plants are used by a small number of people in several regions in Indonesia, but are not as popular as other tubers such as cassava, sweet potato and gadung In researching taka / kecondang tubers that are still growing wildly, some steps are taken which is the first step that must be studied is to determine the varitional characterization of taka / kecondang plants that are spread across the Thousand Islands. Taka needs certain ecological conditions for its growth. Efforts in conserving wild growing kecondang plants is the first step to describe the potential of various types of kecondang spread across Thousand Islands. Characterization of kecondang germplasm is necessary,it can be done through determining the condition of germplasm in Thousand Islands. This germplasm can be characterized in the field or in a laboratory. There are three islands targeted at Thousand Islands, namely Pulau Pramuka, Pulau Karya and Kotok Besar. Characterization needs to be done thoroughly in the regions. Proximate analysis is also needed to determine the carbohydrate content in taka tubers. These efforts are essential in order to support food diversification programs that are part of government agenda..
