“…As reported by previous studies, the appearances of fifteen local accessions of water yam tuber examined exhibited high morphological variation (Fauziah & Mas'udah, 2015;Mas'udah, Fauziah, & Hapsari, 2019;Trimanto & Hapsari, 2015). The tuber shape varied from rounded, oval, cylindrical, to irregular; with smooth or coarse peel texture; with fibrous roots or none; etc.…”

“…Therefore, water yam can be a reliable staple food and an alternative to the food source. In addition, water yam also has a wide range of miscellaneous uses, such as for cosmetics and medicinal purposes, that can be developed in industrial sectors (Chandrasekara & Josheph Kumar, (Fauziah & Mas'udah, 2015;Trimanto & Hapsari, 2015). It has long been cultivated by rural communities extensively and rarely on a large commercial scale.…”

Water yam (Dioscorea alata L.) is an important tuber crop containing essential nutrition as an alternative food source. This study aimed to analyze the biochemical composition and nutritional value of fresh tuber of fifteen local accessions of water yam from East Java and followed by the accession selection for the recommendation of accession with the best nutritional value. Results showed that the nutritional value of proximates including moisture, carbohydrate and fiber were significantly different; except in protein, fat, and ash, with the range of moisture (65.47-82.46%), carbohydrate (17.10-29.37%), protein (1.29-3.00%), fat (0.00-0.29%), fiber (6.70-11.62%) and ash (0.85-1.44%). The ranges of mineral contents (mg/100g) were K (224.54-483.21), Ca (15.63-61.97), Mg (16.75-43.06), Fe (1.40-13.40), Zn (0.43-2.83) and P (329.37-699.91); Na mostly not detected. The anti-nutritions contents (mg/100g) comprised tannin (63.36-167.68) and oxalic acid (12.73-44.92). Analysis through HCA showed three clusters with a range of similarity from 67% to 96%; through PCA scatter biplot clearly illustrated the variation and correlation pattern among local accessions. Six promising accessions are recommended for further breeding and development i.e. Uwi Perti/30, Uwi Bangkulit/36, Uwi Bangkulit/42, Uwi Bangkulit/43, Uwi Biru/58 and Uwi Legi/66, based on their highest carbohydrates and protein content, and the lowest fat content.

Nusa Tenggara consists of some small islands, one of them is Moyo Island. The diversity of plant species in this island is not really known for certain. This research was determined to observe the diversity of plant species in Moyo Island forest. The research was conducted in April 2013 by using floristic analysis method. The characteristic of Moyo Island forest is lowland evergreen rain forest. The results showed there were 60 tree species recorded in Moyo Island forest. There were many fruiting trees and seedling from the trees which show healthy growth, indicated that the plant regeneration in this forest is went well. The diversity of Pteridophytes and orchids were not high. Epiphytic fern which often found in the forest were Drynaria quersifolia and Platycerium bifurcatum and terrestrial orchid that dominated in the forest was Nervilia aragoana. Tuber plant was often found in this forest and grew prolifically were Tacca, Dioscorea and Amorphophallus. In coastal area lived a population of Pandanus tectorius. There were three new record plants found. The first was epiphytic orchid: Pteroceras javanica, the second was the epiphytic plant: Hoya verticillata and wild tuber plant: Tacca leontopetaloides.

“…Farmers in Nganjuk Regency, East Java mostly planted Dioscorea spp. in agroforestry system intercropped with tree plants or in land between rice fields without any special agronomy practices and may harvested about 15-20 tubers per plant (Trimanto and Hapsari 2015). Agro-climatic condition of Bawean Island which is low land area with low intensity of rain and loose soil are optimum for the growth of tuberous plants.…”

Abstract. Trimanto, Hapsari L. 2016. Botanical survey in thirteen montane forests of Bawean Island Nature Reserve, East Java Indonesia: Conservation status,. Bawean Island which located between Borneo and Java islands possessed unique and distinctive abiotic and biotic resources. Botanical survey has been conducted in Bawean Island Nature Reserve. This paper reported the results of inventory study of plant bioresources in 13 montane forests of Bawean Island, discussed their conservation status, bioprospecting on some wild plant species and potential development subjected to some conservation areas. Inventory results in montane forests showed that it was registered about 432 plant species under 286 genera and 103 families; comprised of 14 growth habits in which tree plants were the most dominant with about 237 species. Conservation status evaluation showed that there are at least 33 species of plants included in IUCN list comprised of 30 species categorized as least concern and 3 species considered at higher risk of extinction i.e. Podocarpus rumphii (Near Threatened); Pterocarpus indicus and Memecylon myrtilloides (Vulnerable). Bioprospecting results showed that 10 tuberous plants prospected as food sources; 19 woody plants prospected as timber sources, and 28 plants prospected as ornamental plants. There are at least 7 invasive alien plant species identified including Ageratum conyzoides, Chromolaena odorata, Eupatorium inulifolium, Lantana camara, Imperata cylindrica, Stachytarpheta jamaicensis and Themeda arguens. If well managed, the development of Bawean Island as nature-based and eco-tourism may contribute both to biodiversity conservation and alleviating prosperity of the local residents.
