UJI HERITABILITAS GAHARU (AQUILARIA MALACCENSIS LAMK) UMUR EMPAT TAHUN PADA DEMPLOT DINAS KEHUTANAN KABUPATEN KETAPANG (Test of Heritability of (Aquilaria malaccensis Lamk) For Four Years on The Forestry Agency of Regency Ketapang)
Get PDFAgarwood’s is a product of non timber forest products in the form of lumps, flakes or powder have a distinctive fragrance aroma emanates from the womb chemicals of gubal. The benefits of Aloe for deodorizers, room, body cosmetics, medicines and simple. The stands are agarwood (Aquilaria malaccensis Lamk) in natural forests declined due to logging is done in vain, so type A.malaccensis entered in Appendik II of CITES (Convention On International Trade In Endangered Species). To support the efforts of the conservation and sustainability of production, as well as anticipate the development of value to the market and demand continues to increase, the need to perform planting and cultivation. But this time, high-quality agarwood trees not yet available so that required good quality seeds. Seeds like this can be obtained by using seeds from the tree stem through the process of glorification (test line). One that could serve as the seed-producing trees, the forest is the agarwood (Aquilaria malaccensis) contained in Demplot Forestry District Office of Ketapang. But to point the tree seed producer, should begin by doing a test descent. The problem to date, yet gleaned information genetic properties of the agarwood tree. So that needs to be done heritabilitas/test type a. ardesiacus in Demplot Forestry District Office of Ketapang. This research aims to know the: (1) genetic variation of tree diameter and height added a. ardesiacus; (2) the value of the heritabilitas family on the character height and diameter of plant; (3) genetic traits observed among all the test of a. ardesiacus. The results of the study, expected to be material to obtain tree seed-producing qualified as a superior especially in order planting Aloes in the future. This research uses experimental methods in the form of factorial with Randomised Complete Block Desing then with Deuteronomy as much as 5 blocks and each block consists of 10 families, with 5 number of trees exist, so treeplot 250. The results showed the plant A.malaccensis aged 4 years in demplot showed variation in the nature of plant height and diameter. Variation characteristics of high properties and properties/diameter of the plant is affected by genetic factors as high as estimates the value of heritabilitas to the nature of the height and diameter of the value above 0.8. Based on those results, the selection may be made at Demplot Department of Forestry to locate seeds as a source tree plus with the desired properties criteria. The genetic correlation between height and diameter of the plants shown through analysis of correlation regression, show a positive. The positive correlation show that every high added value added is always followed by the diameter of the plant. Keyword : Test of heritability, A.malaccensis

Get PDFWood is a basic requirement in the industrial activity. while timber production decreased so that required an efficient utilization of wood. The solution to overcome this problem is the use of waste oil palm trunk in the form of composite board. On the other hand, the plastic needs continue to increase. Plastic is a material consisting of artificial inorganic chemicals are quite harmful to the environment so it is necessary to increase the value of plastic. In the process of making this composite board using maleic anhydride (MAH) in order to improve the bonding between the fibers. This study aims to determine the quality of the composite board made from oil palm trunk (Elaeis guineensis Jacq) and polypropylene plastic waste on some variation of the ratio and the percentage of maleic anhydrid (MAH). Variation ratio of plastic and particles were 40 : 60, 50 : 50, and 60 : 40. Percentage of MAH used 0%, 2,5%, and 5% of the weight of the plastic. Composite board size was 30 cm x 30 cm x 1 cm with a target density of 0.8 g/cm3 at compression 25 kg/cm2 with temperature 180ºC for 10 minutes. Evaluation the quality of composite board was refer to standard JIS A 5908-2003. This study used afactorial experiment in a completely randomized design with 2 factors and 3 replications. The result of research showed that the highest guality of composite board was achieved on the highest plastic ratio. The best result was on composite board made from ratio particle oil palm and plastic 40:60 with percentage MAH 2,5%.

The aim of the research are to know the awareness level of Meragun villagers and the factors which have the relationship with the people awareness level toward the GNPF. The research was done in October 2014. The survey method was used in this research. The data analysis was used descriptively by using Chi-Kuadrat toward 87 respondents which was obtained purposively. The research result showed that 48 % of Meragun Villagers have the high level of awareness toward GNPF, 38 % was moderate, and 14 % was low. It was because of the existence of the awareness about the importance of GNPF role for their life. But some people still depend their life to the forest products and live in the area of GNPF. Age factor and knowledge factor have the relationship toward the awareness level with the moderate firmness level, meanwhile the peception factor has the relationship with the high firmness level. For the keeping, protecting, and conserving GNPF necessary make the regulation of forest product harvesting. It will to sustainable the forest product from GNPF.

The purpose of this study was to determine the diversity of bird species and determine the abundance of each species of birds Mangrove Forest region of Tears Permai Village Beach Cloud River right Ketapang. The research was conducted in the mangrove forest along the beach Tears Permai Ketapang about 3 weeks time research done from March 5 to March 25, 2014. The method used in this research is the method of lines, amounting to 5 with the observations one lane per day. Bird species found as many as 61 species with Family 27 and 10 of the Order with the overall individual numbered 916. Diurnal bird community in this region is dominated types Beach Sandpipers (Tringa hypoleucos) and Long-tailed Parrots (Psittavula alexandri). Dominance index value is highest type in the morning and afternoon that the value of C in the morning = 1.2829, C = 1.529 afternoon with the index range D = 1 which means relatively stable. Index of species diversity is highest in the morning with a value of H 'morning = 3.2210 with a range of index H> 3 which means it has a high species diversity. Indeks kemerataan jenis tertinggi terdapat pada waktu pagi dan siang dengan nilai E pagi = 1,8041, E siang = 1,6320 dengan kriteria indeks kemerataan yaitu >1 yang berarti pada waktu pagi dan siang kemerataan jenisnya merata.

DEBIT AIR SUNGAI MELANCAR DI KAWASAN LINDUNG GUNUNG LONCEK KECAMATAN ANJONGAN KABUPATEN PONTIANAK
Get PDFIn addition, water is non biological factor from the forest that has an important role, especially for people who lived in that area. The availability of the water in one area have to be describe to explore that the potential and availability of the water in the area. For Melancar river, there’s no research about the availability of the river water. This research aims to study water debit of Melancar river in protected area of Gunung Loncek in Kecamatan Anjongan Kabupaten Pontianak in rainy and dry. It also explain the condition of vegetation in Gunung Loncek. The results show that water debit of Melancar river in dry days was 0,0278 m3/s and the debit in rainy days was 0,0392 m3/s. The function of the forest in Gunung Loncek area is important to manage water availability, it is shown by the difference of the Melancar river’s debit value between rainy and dry days is not too far evently it is significantly different. The availability of the Melancar river’s water is still good enough and it still can supply people who lived in Melancar river area for their daily used.
