Warni, Helsa Yunilia (2019) Efektivitas Tanaman Riparian sebagai Refugia Berdasarkan Struktur Komunitas dan Diversitas Arthropoda Pengunjung di Saluran Irigasi Buatan Pakis, Malang, Jawa Timur. Sarjana thesis, Universitas Brawijaya.

Indonesian Abstract

Penelitian ini bertujuan untuk menganalisis struktur komunitas dan diversitas Arthropoda pengunjung tanaman riparian di saluran irigasi buatan Pakis, Malang, Jawa Timur, serta efektivitas tanaman riparian berdasarkan profil Arthropoda pengunjung tanaman riparian. Penelitian ex post facto ini dilakukan dengan pengamatan Arthropoda menggunakan metode Visual Encounter Survey (VES) selama 15 menit dan diulang tiga kali di setiap periode. Pengamatan periode I pada pagi hari (07.35-08.30 WIB), periode II pada siang hari (11.00-11.55 WIB), dan periode III pada sore hari (15.00-15.55 WIB) pada tanaman riparian yang dominan: Ipomea aquatica dan Vetiveria zizaniodes (hulu), Hydrocotyle asiatica dan Marsilea crenata (tengah), Scirpus grossus dan Typha angustifolia (hilir) serta pengukuran iklim mikro suhu, intensitas cahaya, dan kelembaban relatif udara. Hasil penelitian menunjukkan bahwa kelimpahan Arthropoda hari pertama 125 individu, hari kedua 82 individu, dan hari ketiga 75 individu yang terdiri dari 11 famili. Tanaman H. asiatica dikunjungi lebih beragam dan lebih banyak Arthropoda, famili Formicidae ditemukan kodominan pada tanaman H. asiatica dan M. crenata, dan indeks diversitas Arthropoda pada semua tanaman riparian tergolong sedang. Tanaman M. crenata dan H. asiatica dikunjungi paling banyak Arthropoda predator sehingga tanaman ini berpotensi sebagai refugia

English Abstract

This study aims to analyse the community structure and diversity of Arthropods in riparian plants in the Pakis artificial irrigation canals, Malang, East Java, and the effectivity of riparian plants based on the profile of Arthropods visitors to riparian plants. This ex post facto was conducted by Arthropods observation using the Visual Encounter Survey (VES) method for fifteen minutes and repeated three times in each period. Period I observations in the morning (07.35-08.30 am), period II in the afternoon (11.00-11.55 am), and period III in the afternoon (15.00-15.55 pm) on dominant riparian plants: Ipomea aquatica and Vetiveria zizanioides (upstream), Centella asiatica and Marsilea crenata (middle), Scirpus grossus and Typha angustifolia (downstream) and measuring the microclimate of temperature, light intensity, and air humidity. The effectiveness of riparian plants can be seen from abudance, taxa richness (TR), important value index (IVI), Shannon-Wienner diversity index (H’), and plant profile. The result showed that the abudance of Arthropods on the first day was 125 individuals, the second day was 82 individuals, and the third day was 75 individuals consisting of 11 families. H. asiatica plants are visited more diverse and more Arthropods, Formicidae family found codominan in H. asiatica and M.crenata plants, and Arthropod diversity index in all riparian plants are medium. The M. crenata and H. asiatica plants are visited by most predator Arthropods so that these plants are potentially as refugia
