Abstract

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.

Abstract

The objective of the study was to increase the growth of 5 provenances albizia (Paraserianthes falcataria L. Nielsen) in the nursery. The experimental design was Split Plot Design, with 5 provenances of albizia as main plot and 3 treatment (wood vinegar application, mychorrizae application and control) as sub plot. Each sub plot consited of 45 seeds as sample,. Growth parameter observed was delta height: that is different beetween measurement at the early application (3 weeks age of seedling ) and at the last measurement (10 weeks age of seedling). The data obtained then analyzed by using analysis of variance of continued with Duncan test. The result showed that mychorrizae and wood vinegar application have significant effect on the growth of albazia seedling. The best performance was shown at wood vinegar application (height average 75,48 cm and height delta 66,62 cm), mychorrizae application (height average 66,44 cm and height delta 59,22 cm) and control (height average 58, 92 cm and height delta 52, 48 cm) respectively. Provenance differences were also significant. The best performance  were shown at provenance of Candiroto, Kediri, Ciamis, Wamena dan Subang. Height delta each provenance after 7 weeks application were 67,65 cm, 62,93 cm, 60,15 cm 53,37 cm dan 53,11 cm; while the total height at the 10 weeks age of seedling were 74,44 cm, 69,33 cm, 69,14 cm, 61,02 cm dan 60,80 cm respectively.

Abstract

Maruca testulalis is one of pest on leaves of Pongamia pinnata (L.) Pierre. leaf in nursery. The objective of this research was to compare the efficacy of insecticides on larvae population and degrees of damage intensity. The research used complete randomized design with five treatments and three replications. The treatments were control, azadirachtin 5 g/l, Bacillus thuringiensis 1 g/l, klorantraniliprol 1 g/l and monosultap 0.5 ml/l. The results showed that tested insecticides influence on the intensity of M. testulalis. Klorantraniliprol azadirachtin and monosultap insecticides were more effective to control the larvae of M. testulalis when compared to B. thuringiensis.

Abstract

Cultivation of albizia as high priority of community forest of West Java in large scale have turned into monoculture stand. These stand has become vulnerable to insect attack such as bagworm. Attack of bagworm took place in the dry season causing growth retardation which in some cases leads to tree death. The aim of this research is to examine the affect of leaf extract of Toona sureni and extract of Beauveria bassiana fungi to kill bagworm and also compare level effectively with organofosfat synthetic insecticides. The result showed that at 7 day after application, highest mortality of bagworm were found on trees treated with T. sureni leaf extract (100%) followed by B. bassiana (92,31%) and organofosfat synthetic insecticides (76,15%).

Abstract

Dalam rangka meningkatkan masa pakai kayu jenis ini, penelitian mengenai pengawetan kayu dengan larutan Boric Acid Equivalent (BAE) 10 % melalui perendaman dingin telah dilakukan. Sampel kayu ganitri (Elaeocarpus ganitrus) dan mahoni (Swietenia mahogany) 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) dan lama perendaman (3 hari, 5 hari dan 7 hari). Parameter yang diamati adalah retensi dan penetrasi bahan pengawet. Hasil penelitian menunjukkan bahwa Perlakuan tebal kayu dan lama perendaman berpengaruh nyata terhadap retensi dan penetrasi bahan pengawet BAE pada kayu ganitri maupun mahoni. Tingkat retensi dan penetrasi bahan pengawet BAE pada kayu ganitri memenuhi persyaratan Standar Nasional Indonesia (SNI) pada semua perlakuan. Sedangkan pada jenis mahoni, tingkat penetrasi bahan pengawet BAE memenuhi standar SNI untuk semua perlakuan, namun tingkat retensi  hanya  memenuhi  standar  SNI  pada  ketebalan  kayu  2,5  cm  dan  5  cm  pada  semua perlakuan lama perendaman. Pada ketebalan kayu mahoni yang lebih tinggi, lama perendaman sampai 7 hari belum dapat mecapai retensi yang memenuhi standar SNI. Berdasarkan hasil analisis, pengawetan dengan menggunakan BAE 10 % yang direkomendasikan adalah lama perendaman 3 hari pada semua ketebalan kayu ganitri, dan ketebalan kayu 2,5 dan 5 cm pada kayu mahoni.

Abstract

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.

Abstract

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
