Abstract

Desa Simo Kecamatan Kendal Kabupaten Ngawi memiliki banyak area kebun, ladang, dan sawah. Kondisi ini mendukung tumbuhnya berbagai umbi. Tujuan dari penelitian ini adalah mengetahui keragaman struktur butir amilum, kerapatan sel idioblas, kadar tepung, dan clustering (pengelompokan) delapan taksa tanaman berumbi di Desa Simo Kecamatan Kendal Kabupaten Ngawi. Sampel umbi yang digunakan 8 taksa umbi yaitu garut (Marantha arundinacea L.), suweg (Amorphophallus campanulatus Bl.), ubi jalar (Ipomea batatas L.), ubi kayu (Manihot esculenta Cranzt), talas (Colocasia esculenta (L.) Schott.), gadung (Dioscorea hispida Dennst.), ganyong (Canna edulis Ker.), dan uwi (Dioscorea alata L.). Umbi yang sudah dikoleksi diamati karakter morfologi umbi, struktur butir amilum, kerapatan sel idioblas, kadar tepung, dan clustering (pengelompokan). Data kerapatan sel yang mengandung butir amilum dianalisis dengan SPSS16 for Windows. Analisis clustering (pengelompokan) menggunakan software PAST. Bentuk butir amilum delapan taksa umbi antara lain: bulat, oval, segitiga, setengah lingkaran, bersudut, dan tidak beraturan. Kerapatan sel yang mengandung butir amilum tertinggi umbi talas (66,33 ± 14,74) sel/mm2. Kadar tepung tertinggi umbi gadung (9,53 ± 2,08%). Berdasarkan analisis clustering terdapat enam kelompok yaitu kelompok pertama uwi, kedua suweg dan gadung, ketiga ubi jalar, keempat ubi kayu dan talas, kelima ganyong, dan keenam garut.

Abstract

The Alas Purwo National Park (APNP) has been designated as a world reserved biosphere by UNESCO. Reserved biosphere is an area consisting of the original ecosystem, unique ecosystems, or ecosystems that have degraded their entire natural elements; therefore, this biosphere is protected and preserved for research and education. To support the protection and preservation efforts, it is important to conduct a basic research for empowering the plant species. This study aimed to characterize the architectural model based on the branching tree and to make a key determination or identification of tree species in the APNP. Exploration of APNP area was conducted using the survey methods; it had been done by passing through the triangulated, going to the bridge Sunglon Ombo until Pancur, then rotating to the cave Istana, the lodge of Sadengan, then going back to the triangulated. The architectural model and the type of branch of trees in APNP were observed. They were stratified by 23 of the known architectural models. The data was descriptively analyzed then the key determination was made. The result showed 11 of tree architecture models consisted of Troll 14 types, Scarrone 4 types, Corner 4 types, Leeuwenberg 3 types, Aubreville 3 types, Mc Clure 3 types, Rauh 5 types, Masart 2 types, Holtum 1 type, Prevost 1 type, and Koriba 1 type. Furthermore, the 11 plants as the examples of the architectural model were described, completed with photos, and notes on endemic species of APNP. The identification key for multiple branching trees also was added depending on the model.
