The purpose of this study was to determine the weed density and the dominant species of weeds in Malapari (Pongamia pinnata (L). Pierre) agroforestry. The study was conducted in Patutrejo Village, Grabag District, Purworejo Regency. The method used is single plot method in malapari agroforestry, as a comparison of observations of weeds on empty land that is not planted. Weed sample collection was carried out by the quadratic method measuring 1 m x 1 m as many as 3 plots placed in malapari agroforestry and empty land diagonally. Observations were repeated 3 times so that there were 18 observation plots. The results showed that weed density in malapari agroforestry (29.95) was lower than empty land (54.17). The dominant species of weeds in both malapari agroforestry and empty land is Eulalia amaura (Buese) with Important Value Index (IVI) of 36.40 % and 43.39 %. This species is a pioneer weed and fast growing, so monitoring and control are needed so that the weed population is not economically disserve.Keywords: agroforestry, density, dominant, malapari, weed

ABSTRAKPenanaman talas beneng (Xanthosoma undipes K.Koch) di bawah tegakan hutan rakyat dapat berkontribusi bagi ketahanan pangan, peningkatan pendapatan masyarakat dan perbaikan kualitas lingkungan. Tujuan penelitian ini adalah untuk melakukan evaluasi pertumbuhan talas beneng pada pola agroforestri dan monokultur. Penelitian dilakukan dengan observasi lapangan terhadap 2 (dua) pola tanam talas beneng yaitu agroforestri dan monokultur di hutan rakyat Desa Pagerageng, Kecamatan Pagerageung, Kabupaten Tasikmalaya. Hasil penelitian menunjukkan bahwa seluruh parameter yang diamati berbeda nyata antar kedua pola tanam. Tinggi tanaman, lebar daun dan panjang daun talas beneng pada pola agroforestri sebesar 107,3 cm, 43,6 cm dan 64,7 cm, pada pola monokultur sebesar 42,4 cm, 19,8 cm dan 31,4 cm. Pertumbuhan talas beneng yang lebih tinggi pada pola agroforestry mengindikasikan bahwa jenis ini cukup potensial untuk dikembangkan dibawah tegakan pohon. Kata kunci: agroforestri, monokultur, talas beneng, pertumbuhan, produktivitas

ABSTRACT Development of manglid private forests is experiencing challenges with sucking insects attack of Urostylissp. which inhibits the growth of manglid until death. This study aims to identify the attack percentage and attack intensity of the sucking insects on monoculture, manglid agroforestry, and control efforts. The methods used were exploration and experiment. The results showed that the attack percentage of Urostylis sp. on monoculture and agroforestry patterns were 59% and 53% respectively. Attack intensity of Urostylis sp. on monoculture and agroforestry pattern were 55% and 31% respectively. Pests control using a biological insecticide of 1 g/l Bacillus thuringiensiseffectively caused mortality up to 95% while the botanical insecticide using 5 ml/l Azadirachtin was more effective as a repellant. Pest control of Urostylis sp. using 1 g/l B. thuringiensis can be done during the early dry season.
