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.

Soil macro fauna is one of the bio indicators in determining the quality of the land. The total soil macro fauna is influenced by the climatice condition and land utilization pattern. Agroforestry is one of type land utilization that is expected to improve the soil fertility. Land utilization changing from monoculture into agroforestry is predicted to influence the soils macro fauna. This study is aims to find out the population of soil macro fauna before and after applying manglid agroforestry. The research was conducted in Cukangkawung, Tasikmalaya District, West Java Province. Sample of macro fauna was taken from non-productive land of tea plantations and one year after the land was planted by manglid + corn + peanut by using agroforestry. Samples were taken in Feb-March 2015 and once more in Feb-March 2016. The observation land area is 1 hectare that is divided into 1 m x 1 m - 16 observation plots that was placed randomly. In each plot, a hole of 30 cm in depth was made and the dug out soil was placed on the plastic container. The collected macro fauna was counted and placed into a bottle that was filled with 70% alcohol. The macro fauna identification was conducted in LIPI zoology laboratory. The research shows that the diversity indexes for Shanon and Margalef on manglid agroforestry are higher than on the ex tea land. Factors that influence the soil macro fauna diversity improvement is pH, low temperature of soil and high soil moisture. Soil macro fauna becomes organic decomposer in agroforestry for about 56,25% and 20% in non-productive land of tea plants.

The purpose of this research is to compare the intensity attack of G. agamemnon on monoculture and manglid agroforestry patterns , to identify G. agamemnon parasitoid and to compare the level of parasitization on monoculture and manglid agroforestry patterns. The method used is direct observation of manglid with parameters such as G. agamemnon intensity attack on monocultur and agroforestry, morphology identification of parasitoid type and parasitization level on monoculture and agroforestry. The results showed that G. agamemnon attack on monoculture pattern reached 39.25 % and 25.75 % on agroforestry pattern. The type of parasitoid that attacks G. agamemnon larvae is Diaparsis sp. Parasitization of Diaparsis sp . on monoculture and agroforestry manglid pattern were 55.00 % and 66.67%. Keywords: D iaparsis, G raphium, manglid , parasitoid , pest.

Tisuk ( Hibiscus macrophyllus Roxb.) adalah salah satu jenis tanaman cepat tumbuh yang banyak dikembangkan di hutan rakyat, terutama di Pulau Jawa. Salah satu kelemahan jenis ini adalah tingkat keawetannya yang rendah (kelas awet III/IV). Dalam rangka meningkatkan masa pakai kayu tisuk, penelitian mengenai pengawetan kayu tisuk dengan larutan Boric Acid Equivalent (BAE) melalui perendaman dingin telah dilakukan. Sampel kayu tisuk berasal dari hutan rakyat di Desa Sukamulih, Kecamatan Sariwangi, Kabupaten Tasikmalaya. Perlakuan yang diterapkan adalah tebal kayu (2,5 cm, 5 cm, 7,5 cm dan 10 cm), immersion time (3 hari, 5 hari dan 7 hari), dan konsentrasi bahan pengawet (5 %dan 10 %). Parameter yang diamati adalah retensi dan penetrasi bahan pengawet. Hasil penelitian menunjuk-kan bahwa retensi bahan pengawet berbeda nyata pada perlakuan tebal kayu tetapi tidak berbeda nyata pada kedua perlakuan lainnya. Sementara, tingkat penetrasi bahan pengawet tidak berbeda nyata pada semua perlakuan. Retensi dan penetrasi bahan pengawet menunjukkan nilai yang memenuhi persyaratan SNI. Berdasarkan analisis ini, pengawetan kayu tisuk yang disarankan menggunakan BAE adalah konsentrasi bahan pengawet 5 % dengan waktu perendaman 3 hari pada ketebalan 2,5 cm, 5 cm, 7,5 cm dan 10 cm.
