Abstract

Abstrak Primata merupakan salah satu fauna arboreal di hutan yang memiliki arti penting dalam kehidupan alam. Keberadan primata sangat penting artinya dalam regenerasi hutan tropik. Penelitian ini bertujuan untuk mengetahui pola penyebaran harian, populasi, serta identifikasi jenis tumbuhan pendukung terutama sebagai pakan M. fascicularis. Pengamatan penyebaran dan populasi  monyet dilakukan di kawasan hutan rakyat yang terletak di desa Ambender Kecamatan Pegantenan, Kabupaten Pamekasan. Pemetaan penyebaran harian dan daerah edar dilakukan dengan menggunakan peta dengan plotting area aktivitas harian M. fascicularis. Estimasi populasi monyet dilakukan dengan metode terkonsentrasi di lima titik pengamatan. Parameter yang diamati dalam estimasi populasi adalah jumlah, struktur umur, jenis kelamin, dan arah pergerakannya. Penentuan jenis makanan monyet dilakukan dengan metode focal animal sampling yaitu mengamati satu individu dalam jangka waktu tertentu. Proporsi tumbuhan pendukung dilakukan dengan metode kuadrat dan dihitung proporsinya terhadap seluruh tumbuhan yang ada. Identifikasi jenis tumbuhan dilakukan secara langsung di lapangan dan jika tidak memungkinkan dibuat herbarium dan diidentifikasi di laboratorium. Hasil penelitian menunjukkan monyet melakukan penyebaran harian dengan pola tertentu. Terdapat beberapa jenis tumbuhan yang menjadi pilihan M. fascicularis sebagai pakannya. Diantaranya terdapat sekitar 22 tumbuhan hutan yang teridentifikasi dan diketahui dipilih oleh M. fascicularis sebagai pakannya, jenis tumbuhan tersebut antara lain duwek (Syzygium cumini), nyato (Palaquium eriocalyx), kalak (Uvaria purpurea), polai (Alstonia scholaris), kendal (Cordia gantamensis), dan sanek (Capparis acuminata).   Kata Kunci: M. fascicularis, Pola penyebaran, Karakteristik tumbuhan pakan

Abstract

A study on soil arthropod abundance, diversity and composition have been done on November 2016 to March 2017 using pitfall traps. The objective of this study is to analyze variations of the soil arthropod abundance, diversity and composition among different habitats in a university forest.  The study was carried out in Universitas Brawijaya Forest (UBF) Malang, East Java (7°49S, 112°34E, 1,200 m in altitude), consisted of four locations: an agroforestry (AF), a gallery forest (GF), the pine stands (PS) and a settlement yard (SY). At each site, a total of 10 traps (5 by 2 rows) were placed systematically at 4-m intervals. Glass cups (10 cm in diameter and 7 cm deep) were buried in the ground during 24 hours. There were 2286 individuals of arthropod collected from all sampling locations. Overall the samples collected consist of 41 families of arthropods. The abundance (mean ± SE) of soil arthropod was highest in PS and the lowest in SY. Statistically, variations in abundance among locations were significant (F = 7.39, p < 0.01). The taxa richness of arthropod was highest in GF and the lowest in SY. Statistically, variations in taxa richness among locations were significant (F = 4.26, p < 0.05).  The diversity was the highest in the GF (1.9 ± 0.1) lowest in the SY (0.74 ± 0.1). Statistically, variations in diversity among study sites were significant (F = 26.73, p < 0.001). In general, scavenger dominated the composition of soil arthropods. The highest proportion of scavenger abundance present in SY was 84.9%, while the lowest in the GF was 29.3%. The highest litter transformer composition in GF was 33.9%, and the lowest in SY was 8%. The highest decomposer in PS was 26.9% and the lowest in AF was 12.9%. The highest predator in AF was 20.7% and the lowest in SY was 1%. Compositions of soil arthropod were affected by environmental factors such as soil temperature and light intensity.

Abstract

A study on the effect of refugia areas to attract on Arthropods has been done in a semi-organic paddy field in Malang, from March to June 2017. The arthropod was measured by abundance, diversity and composition variables. Arthropod observations were performed on 6 plots of 1 m2 each, consisting of 3 plots on the side near the Refugia area (treatment) and 3 plots on the opposite side (control). The refugia areas consisted of plants as follows chili (Capsicum frutescens), the wild cosmos (Cosmos caudatus), the long beans (Vigna unguiculata), and Marigold (Tagetes erecta). The visual encounter surveys method was conducted for 15 minutes on each plot. There were 2249 individuals of Arthropod observed visually in the study sites. This study showed that of the abundance (mean ± SE) of Arthropod visitors was lower in plots adjacent to refugia areas (treatment) (33.7± 2.63), than that far from Refugia area (control) (38.33 ± 2.54); while the taxa richness and diversity was higher found in treatment plots. The species richness in the treatment plots (12.2 ± 0.70) was higher than that in control (9.70 ± 0.51). The diversity of Arthropod visitors in the treatment plots (2.10 ± 0.07) was also higher than that in control (1.71 ± 0.07). Proportion of predator in the treatment plots was almost twice higher (33.14) that in the control plots (17.65); while that of herbivore was vice versa. This meant the refugia areas have attracted more predators. The composition of Arthropod visitors was remarkable affected by treatment. The abundance of common predator families such as Coccinellidae, Coenagrionidae and Oxyopidae were higher in treatment plots.
