Budiharto, IvoneWulandari (2011) Kontribusi Arthropoda Kanopi dalam Menjaga Stabilitas Ekosistem pada Kebun Berbasis Sengon Laut (Paraserianthes falcataria (L.) Budidaya Porang (Amorphophallus muelleri Blumei) (Schott) di Jember. Magister thesis, Universitas Brawijaya.
Abstract
Pengembangan sistem agroforestri berbasis Sengon Laut dengan tanaman budidaya Porang dianggap telah berhasil terhadap tingkat ekonomi masyarakat. Penelitian ini bertujuan untuk menganalisis dan membandingkan diversitas, komposisi, struktur komunitas Arthropoda kanopi pada dua lokasi berbeda (lahan kebun Sengon Laut budidaya Porang dan non Porang) yang tertarik pada perangkap bejana berwarna biru dan kuning, mengetahui variasi vertikal diversitas, kelimpahan dan struktur komunitas Arthropoda kanopi, untuk mengetahui hubungan komunitas Arthropoda kanopi dengan faktor abiotik dan untuk memberikan rekomendasi tentang pengelolaan lahan kebun. Pencuplikan Arthropoda di dua lokasi menggunakan perangkap bejana kuning dan biru digantungkan pada ketinggian kanopi bawah (1 – 1,5 m) dan ketinggian kanopi atas (8 – 10m). Pengukuran faktor lingkungan (suhu dan cahaya) dilakukan disetiap lokasi. Analisis vegetasi non crop dilakukan dengan menggunakan metode line intercept dan vegetasi pohon menggunakan metode perhitungan lengkap. Analisis data perbandingan struktur komunitas antar lokasi didapatkan dari nilai penting dan diversitas (indeks Shannon-Wiener ). Kesamaan komposisi dua lokasi dianalisis menggunakan (indeks kesamaan Bray-Curtis ) dan pola variasi vertikal dianalisis dengan Anova. Komposisi Arthropoda kanopi dan korelasinya dengan faktor lingkungan dianalisis dengan pearson correlation . Arthropoda kanopi yang dikoleksi pada lokasi lahan Porang memiliki kelimpahan yang lebih rendah (329 individu) sedangkan pada lokasi lahan non Porang Arthropoda kanopi yang dikoleksi memiliki kelimpahan lebih tinggi (829 individu). Perolehan hasil individu Arthropoda kanopi tertinggi didapatkan lebih banyak pada bejana berwarna kuning dan pada ketinggian bagian kanopi atas pada lahan non budidaya Porang dibandingkan dengan lahan budidaya Porang. Nilai indeks keanekaragaman Arthropoda kanopi diperoleh pada lahan non Porang lebih besar (2.56) dibandingkan dengan lahan Porang (2.05). Kelimpahan Arthropoda kanopi antar dua lokasi, warna dan ketinggian berbeda nyata dengan P 0.05. Kesamaan antara dua komposisi Arthropoda kanopi pada lahan budidaya Porang dan non budidaya Porang dengan indeks Bray Curtis sebesar 0.60% Struktur komunitas pada lahan Porang didominasi oleh spesies Simulium sp. dengan nilai INP 22.42% sedangkan pada lahan non Porang didominasi oleh spesies Oxyopes sp. dengan nilai INP 20.75%. Jumlah dan jenis vegetasi non crop serta diameter pohon pada lahan non budidaya Porang memiliki nilai lebih besar dibandingkan dengan lahan budidaya Porang. Analisis faktor lingkungan suhu udara dan intensitas cahaya terhadap kelimpahan Arthropoda kanopi didapatkan korelasi yang positif dan berdampak secara signifikan dengan korelasi P- value 0.05. Rekomendasi kepada petani untuk pengelolaan lahan secara baik adalah vegetasi non crop di area tanaman budidaya tidak dibersihkan dan tidak melakukan penyemprotan pestisida.
English Abstract
development of agroforestry based of Sengon Laut with Porang crop area has successfully to increase people economic level. This research aimed to analyze and compare diversity, composition, structure community of canopy Arthropod at two different location (Sengon Laut of Porang crop area and non porang crop area) which was attracted to blue and yellow colored water pan trap, vertical variation diversity, abundance, and structure community of canopy Arthropod, to know relation between community of Arthropod canopy with abiotic factor at local agroforestry and to recommend good cultivating management. Samples of canopy Arthropod was taken at two different location by blue and yellow colored water pan trap, which was hang on bottom layer (1-1,5 m) and upper layer (8-10 m). Abiotic factors (Temperature and light intensity) were measured at each location. Non crop vegetation was analyzed by line intercept method and tree vegetation was analyzed by complete count method. Data of structure community comparison each location was analyzed by important value and diversity (Index Shannon-Whienner). degree of same level composition between two location was analyzed by Index Bray-Curtis and variation vertical analyzed by anova. Canopy Arthropod composition and relation with abiotic factors was analyzed by Pearson Correlation with MINITAP program. value abundance of canopy Arthropod in Porang crop area was (329 individu), fewer than canopy Arthropod in non Porang crop area which was (829 individu). result showed that yellow water pan trap had better efficiency on upper layer at non Porang crop area than porang crop area. value Diversity canopy Arthropod index from non Porang crop area was (2.56) more than Porang crop area which was (2.05). abundance of canopy Arthropod among two locations, color, and hight were significant different with P 0.05. value of both communities was 0.60% were measured in this research, indicated that difference of Arthropod composition had a similarity. Community Structure were dominated by Simuliium sp. in both of areas with number of important species index 22.42% in Porang crop area and in non Porang crop area community structure were dominated by Oxyopes sp. in both of areas with number of important spesies index 20.75%. Number of variet non crop vegetation and diameter tree at non porang crop area was greater n Porang area. Analysis of abiotic factor (temperature and light intensity) had positif correlation affect significantly with P-Value correlation 0.05. Recommendation to farmers in order to make good cultivation management non crop vegetation is not cleaned and not used pesticide utilization.
