YuanitaNoviantari (2009) Pemetaan Persebaran Lahan Budidaya dan Karakter Populasi Pandanus tectorius Sol. ex Park. di Kabupaten Jombang Jawa Timur. Sarjana thesis, Universitas Brawijaya.
Abstract
Tujuan dari penelitian ini adalah menentukan peta persebaran lahan budidaya , sosiabilitas, vitalitas, periodisitas dan stratifikasi populasi pandan di Kabupaten Jombang. Peta persebaran ditentukan dengan cara merekam posisi koordinat lahan menggunakan GPS. Pengamatan terhadap sosiabilitas, vitalitas, periodisitas dan stratifikasi populasi pandan dilakukan dengan analisis vegetasi kualitatif pada lokasi lahan budidaya di tiap desa. Stratifikasi dilakukan dengan menentukan tinggi tanaman yang diukur dengan menggunakan meteran. Sosiabilitas diamati pada bentuk populasi pandan dan diberi nilai berdasarkan pada sistem penilaian Braun-Blanquet. Vitalitas diamati terhadap siklus hidup pandan melalui keberadaan tunas-tunas, habitus semak dan pohon. Periodisitas diamati dari keberadaan bunga dan buah. Rekaman koordinat dan atribut populasi yang didapat dari hasil pengamatan tersebut kemudian ditampilkan pada peta dasar menggunakan software ArcGIS 9.1. Berdasarkan hasil eksplorasi di lima kecamatan, diketahui terdapat 23 desa yang masih membudidayakan pandan. Lahan budidaya banyak tersebar di Kecamatan Kabuh, Kudu dan Ngusikan dengan jumlah tanaman mencapai >1000 individu di tiap lokasi, sedangkan di Kecamatan Ploso dan Plandaan sebarannya hanya sedikit dengan jumlah tanaman <500 individu. Sosiabilitas pandan di tiap desa berkisar antara 2 hingga 3 yang berarti individu pandan rata-rata ditanam secara berderet dalam populasi yang besar yaitu berjumlah >100 individu. Populasi pandan tersebut berada pada stratum D dimana terdiri dari semak yang tingginya berkisar antara 1-4 m. Nilai vitalitas di semua desa bernilai tiga yang berarti terdapat regenerasi tunas, habitus semak tetapi tidak ditemukan pohon. Periodisitas pandan bernilai empat dipengaruhi oleh nilai vitalitas yang berarti tidak ditemukan bunga maupun buah. Nilai-nilai yang didapat dari hasil pengamatan tersebut tidak lepas dari pengaruh manusia yang membudidayakannya.
English Abstract
The purpose of this research were to determine the cultivated land distribution, sociability, vitality, periodicity and stratification of screwpine population in Jombang. The map distribution was constructed by recording the coordinate position of cultivation area using GPS. Observation to sociability, vitality, periodicity and stratification was done by qualitative vegetation analysis in every villages. Stratification was done by determining the plant height which was measured using ruler. Sociability was observed from shape of screwpine population and given value based on Braun-Blanquet’s scoring system. Vitality was observed from screwpine life cycle through bud, tree and shrub presence. Periodicity was observed from flower and fruit presence. Coordinate records and population attribute would be displayed on base map using ArcGIS 9.1 software. Based on exploration result, there were 23 villages that was still cultivating screwpine. Cultivate lands were many distributed in Kabuh, Kudu and Ngusikan with the individual number up to >1000 individuals on each land, on the other villages there was just a little distribution in Ploso and Plandaan with the number of plants were below 500 individuals. Screwpine sociability in every villages was about two to three that means approximately screwpine individuals were planted in a row in big population up to >100 individuals. That screwpine population was laying on D stratum which was consisting of shrubs having 1-4 meters in height. The vitality value in all village was three, that means there were buds regeneration, shrubs but there was no tree. Periodicity of screwpine value has four which was affected by vitality attribute. Value which was got from that observation were influenced by human.
