Abstract
Porang (Amorphophallus muelleri Blume) merupakan salah satu tumbuhan lokal Indonesia yang banyak tersebar di Pulau Jawa. Tujuan dari penelitian ini adalah untuk mengetahui keberadaan porang di wilayah Malang Raya dan mengonstruksi peta persebaran porang berdasarkan topografi wilayah. Metode penelitian terdiri dari kegiatan eksplorasi porang dan pembuatan peta persebarannya. Eksplorasi dilakukan di Malang Raya yang meliputi Kota Malang, Kabupaten Malang dan Kota Batu. Porang yang ditemukan dicatat koordinat lokasi dan kelimpahannya, kemudian dibuat peta persebaran porang dengan menggunakan software Quantum GIS. Berdasarkan hasil eksplorasi di Malang Raya, porang ditemukan di 12 lokasi dan tersebar di 8 kecamatan di Kabupaten Malang. Porang yang ditemukan berupa porang liar (9 lokasi) dan porang budidaya (3 lokasi). Satu lokasi populasi porang dapat memiliki plot (1x1 meter) berjumlah 2 – 112 plot dan setiap plot dapat ditemukan 1 – 24 individu porang. Berdasarkan topografi wilayah, setiap lokasi memiliki ketinggian bervariasi antara 34 – 931 meter di atas permukaan laut. Kemiringan lokasi antara 4,96° – 30,87° dan terklasifikasi dalam area agak miring hingga curam (kelas C - F). Namun porang banyak ditemukan di daerah lereng miring (kelas D). Di Malang Raya, porang umumnya tumbuh di bawah tegakan bambu dan jati. Peta persebaran porang di Malang Raya ini diharapkan dapat memberikan kontribusi bagi tersedianya informasi lokasi dan kondisi keberadaan porang di suatu wilayah di Pulau Jawa.
English Abstract
Porang (Amorphophallus muelleri Blume) is one of the Indonesian local plant that widely distributed in Java Island. The aims of this research were to know about porang distribution in Malang Raya and to construct porang distribution map based on region topography. The research method consisted exploration activity and made of porang distribution map. Exploration was conducted in Malang Raya which includes Malang City, Malang District and Batu City. Porang that found during exploration was noted the location coordinates and abundance then made porang distribution map using Quantum GIS software. Based on the result of exploration in Malang Raya, porang found in 12 locations and spread across in 8 subdistricts in Malang District. Porang that found during exploration consist of wild porang (9 locations) and cultivated porang (3 locations). One location of porang population can have a plot (1x1 meter) between 2 – 112 plots and each plots can be found 1 – 24 individuals porang. Based on region topography, each location has altitude varying between 34 – 931 meters above sea level. The slope location is between 4,96° – 30,87° and classified in the area at a slight angle to steep (C – F class). However porang were found in the angled slope area (D class). In Malang Raya, porang generally grow under stands of bamboo and teak tree. Porang distribution map in Malang Raya is expected to contribute to the information availability of locations and conditions of porang existence in a region in Java Island.
