PERSEBARAN DAN KARAKTERISASI MORFOLOGI LENGKIR (Tacca leontopetaloides L. Kuntze) SEBAGAI SUMBER PANGAN DI PULAU BANGKA

Food plants is a type of plant in which there are carbohydrates and proteins that can be used as a source of energy for humans. one of which is lengkir. Lengkir growth wild and can found started from the edge of the sea 0 mdpl to a height of about 220 mdpl. This study aims to inventory and characterize lengkir in Bangka island. The research method consists of determining the location of the distributioan lengkir by purposive sampling and morphological characterization. The results showed that the number of individuals most found in Bangka Tengah is 678 individuals and the least in the city of Pangkalpinang is 16 individuals. The conclusion of this study that the lengkir found in all districts of the island of Bangka with the pattern of distribution groups. A map of the distribution of lengkir on the Bangka island is expected to contribute to the availability of the location information and the conditions of existence lengkir in Bangka island

Dipterocarps protected by Jering local wisdom in Jering Menduyung Nature Recreational Park, Bangka Island, Indonesia

Apart of the oil palm plantation expansion, the Jering Menduyung Nature Recreational Park has relatively diverse plants. The 3,538 ha park is located at the north west of Bangka Island, Indonesia. The minimum species-area curve was 0.82 ha which is just below Dalil conservation forest that is 1.2 ha, but it is much higher than measurements of several secondary forests in the Island that are 0.2 ha. The plot is inhabited by more than 50 plant species. Of 22 tree species, there are 40 individual poles with the average diameter of 15.3 cm, and 64 individual trees with the average diameter of 48.9 cm. The density of Dipterocarpus grandiflorus (Blanco) Blanco or kruing, is 20.7 individual/ha with the diameter ranges of 12.1 – 212.7 cm or with the average diameter of 69.0 cm. The relatively intact park is supported by the local wisdom of Jering tribe, one of indigenous tribes in the island. People has regulated in cutting trees especially in the cape. The conservation agency designates the park as one of the kruing propagules sources in the province. The growing oil palm plantation and the less adoption of local wisdom among the youth is a challenge to forest conservation in the province where tin mining activities have been the economic driver for decades. More socialization from the conservation agency and the involvement of university students in raising environmental awareness is important to be done

Persebaran dan Karakterisasi Morfologi Tumbuhan Lengkir (Tacca leontoptaloides L. Kuntze) Sebagai Sumber Pangan Alternatif di Pulau Bangka

Tumbuhan pangan merupakan jenis tumbuhan didalamnya terdapat karbohidrat dan protein yang dapat digunakan sebagai sumber energi bagi manusia. Salah satu contohnya ialah lengkir. Lengkir tumbuh liar dan dapat ditemukan mulai tepi laut 0 mdpl hingga ketinggian sekitar 220 mdpl. Penelitian ini bertujuan untuk mendata dan mengkarakterisasi lengkir di Pulau Bangka. Metode penelitian terdiri atas penentuan lokasi persebaran lengkir secara purposive sampling dan karakterisasi morfologi. Hasil penilitian menunjukkan bahwa jumlah individu terbanyak ditemukan di Kabupaten Bangka Tengah yaitu 678 individu dan yang paling sedikit di Kota Pangkalpinang yaitu 16 individu. Kesimpulan dari penelitian ini bahwa lengkir ditemukan disemua Kabupaten Pulau Bangka dengan pola persebaran berkelompok. Peta persebaran lengkir di Pulau Bangka ini diharapkan dapat memberikan kontribusi bagi tersedianya informasi lokasi dan kondisi keberadaan lengkir di Pulau Bangka
