Keanekaragaman Jenis Pohon Di Hutan Pendidikan Konservasi Terpadu Tahura Wan Abdul Rachman
Get PDFEducational Forest is place for the public, especially students and researchers to study the interrelationship between the components of the forest ecosystem. Information on the types of trees is one of the basic information for education and the development and management of educational forest. This study is performed to fill a gap where information regarding biodiversity in Educational Forest of Tahura Wan Abdul Rahman is lacking. Sampling intensity used was 0.12% of the 1,143 ha forest area of education, so that is an area of 1.37 ha sample plots. Sample plot consisted of 10 plots in the sub-blok protected and 24 plots in sub-blok social forestry. It was found that 60 tree species were registered, which comprised of 41 species of trees scattered in the sub-blok protected and 19 species in sub-blok social forestry. Diversity Index in the sub-blok protected was 1.45 and is dominated by the kind of Kenari (Canarium commune) with 26.98% of Key Value Index. Diversity Index in the sub-blok social forestry was 1.09 and is dominated by Durian (Durio zibethinus) with 67.28% of Key Value Index

Pengaruh Beberapa Dosis Pupuk Dan Beberapa Media Tumbuh Terhadap Pertumbuhan Bibit Jabon (Anthocephalus Cadamba)
Get PDFJabon wood (Anthocephalus cadamba) is a fast growing species.Currently, jabon wood is play an important rile for timber industry, included plywood, lamina, and the other timber industry.To improve the quality of wood jabon, necessary for the addition of fertilizer and improved media.Application of multiple doses of fertilizers with several media compositions was expected could increase the growth of jabon wood seedling.This observation aimed to know the effect and interaction of media composition and fertilizer on the growth of jabon wood seedling.The observation was conducted in greenhouse of Agriculture Faculty, Lampung University for 4 months.The observation was compiled factorially (3x4) in a completely randomized design (CRD) with 3 replications. The first factor was the composition of the soil medium consisting of red-yellow podzolic (100%); red-yellow podzolic + sand (1:1); red-yellow podzolic + rice husk (1:1), while the second factor was the dose of fertilizer consists of 0 g, 0.5 g , 1 g, and 1.5 g. The observed variables are added height, diameter, number of leaves, root length, and total dry weight.The results showed that media composition significantly affected, diameter, number of leaves and total dry weight.Fertilizer did not significantly affected height increment, diameter, number of leaves, root length, and total dry weight, there was no interaction between several media compositions with fertilizer. The best treatment to all growth parameters was red-yellow podzolic soil + sand (1:1) with all fertilizer doses. Keywords: fertilizer, jabon wood, podzolic,red-yellow, rice hus
Pengaruh Jumlah Ruas Cabang Terhadap Pertumbuhan Setek Bambu Hitam (Gigantochloa Atroviolacea)
Get PDFBlack bamboo (Gigantochloa atroviolacea) is one of the famous bamboo species used, because it has many functions.The effort to maintain bamboo population is by cultivation. Generative cultivation of bamboo is difficult, so that vegetative cultivation by branch cuttings is carried. The aim of this research were to know the effect of number of internodes on black bamboobranchcuttings and the best influence on percentage of life and growth.The experiment used Completely Randomized Design(CRD) with 3treatmentsand 5replications.The treatmentwerenumber ofblack bamboobranch, which were2, 3,and 4 internodes. Eachbranchesplantedin polybag had filledwith top soil.The growth variablesthat measured were the percentage of life, number of shoots, length of shoot, diameter of shoot, number of leaves andlength of root. Theresults showed that thenumber of black bamboo branchinternodesinfluenced onlength of shoot and number of leaves. Blackbamboobranch with 4 internodeswas thebestresultto growth ofblackbamboobranchcuttings because of highestvalue onlength of shoot (3.84 cm) and number of leaves(4.90 sheet).

The results showed that the daily behavior of doves on the tennis court Lampung University include : perch, moving, flying, silent, eating, resting, incubating eggs, feathers browse, and make a nest. Activity that most people do is sit with the frequency and percentage of 36.47 % and a 9.3 times when there is human activity, 7.8 times and 30.11 % when there is no human activity. Activity that is at least eat the frequency and percentage of 0.1 times and 00:39 % when there is human activity, 0.3 times and 1:15 % in the absence of human activity. Doves keep doing the activity on the tennis court for tennis has a good habitat conditions for rest , a place to sleep, breed, and safe from threats and harassment
Dinamika Kepemilikan Perkebunan Kelapa Sawit Di Provinsi Riau Sumatra Indonesia
No full textSmallholder’s plantations represent 44% of oil palm in Indonesia, and they were known to have agronomic performance much lower than Estate ones. So there is large room for increasing the yield with sustainable cropping system. To better understand the heterogeneity of smallholder’s plantations, an agricultural diagnosis has been implemented in a specific place, Riau Province of Sumatra. This study led to well characterize the dynamics of plantation in the region and the diversity of rationalities. Among eight existing types of smallholding plots, there were only three types with yield hardly lower than those of the estate plantations. This reinforced the interest to implement diagnosis through the nutritional status of palms using data from foliar diagnosis and soil analysis.
