Abstract

The needs of wood as a main ingredient of paper is constantly increasing. To overcome its problem one of the alternative solution is  Industrial Plantation  Forest  (HTI). Eucalyptus pellita is one of the type which is developed for HTI that is necessary to be provided adequate and quality seeds, it is necessary to propagation the plant of Eucalyptus pellita. Stump out of the wood Eucalyptus pellita can produce the new coppice that can produce seed plants and can be developed by propagation of plants as vegetative by cuttings. One of the factors that affect the success rate of cuttings is the planting media. The problem is what is the proper planting media in developing the growth of coppice cuttings from the stump of the wood Eucalyptus pellita. The purpose of this study is to determine the appropriate planting media to be used on coppice cuttings from the rest of the harvest Eucalyptus pellita. The method used in this study is Completely Randomized Design (CRD). The results showed that the use of planting media peat or compost and rice husk or compost and rice husk with a ratio of 3:1 and 1:1 as well as the addition of coconut fiber powder at the top of the media can be used as a planting medium coppice cuttings from stump rest of logging Eucalyptus pellita. Keywords: coppice, cuttings, planting media, Eucalyptus pellita

The used of data is primary data and secondary data, that have a simillar in quality and quantity.            The value of investment criteria was used in this research is : Net Present Value (NPV), Net Benefit Cost Ratio(Net B/C), Internal Rate ofReturn (IRR), Payback Period (PP), and Analysis of Sensitivity if cost for cow waste has changed 10%. The value of  Social Opportunity of Capital (SOCC) as discount factor is 12%. The value of Net Present Value (NPV) during age of business activity of equal toRp. 306.352.725,46. The value of Net Benefit Cost Ratio(Net B/C) is 5,14, that was meaning output Rp.1,00 will give back Rp. 5,14. The value of IRR is 51,53%, it was meaning the ability toreturn the capital is more than discount factor, and Payback Period of equal to28,61 months or about 4 year and 7 months, and it’s meaning return of investation  the biodygester operate obtained after 4 years and 7 months. Analysissensitivity of the changed of cost input around 10%, NPV of equal toRp.232.770.721,58.

Abstract

This study aims to determine the effect of sludge and liquid manure as well as to obtain the best dose of sludge and liquid fertilizer for the growth of oil palm seedlings in ultisol media. Research conducted at the Experimental Farm, Faculty of Agriculture, University of Riau Pekanbaru. The study was conducted during the four months from April to August 2015. The study conducted an experiment using a completely randomized design (CRD) with 2 factors and 3 replications. The first factor is the sludge (S), which consists of 4 levels and the second factor is fertilizer complementary liquid (P) consisting of 3 levels. Comparisons between treatment parameters observed were seedling height, number of leaves, the girth, shoot to root ratio, root volume, seedlings dry weight using ANOVA and Duncan's multiple range test level of 5%. The results showed that the application of sludge and PPC has no significant effect on seedling height, number of leaves, girth, shoot to root ratio, seedling dry weight and root volume. Sludge 75 g / polybag and PPC 4 cc / l applications on pre nursery oil palm seedlings in ultisol media tend to improve seedling height, number of leaves, wrap tubers, roots canopy ratio, seedling dry weight and root volume. Keyword : Coconut Oil, Sludge, Fertilizer Complement Liquid, Ultisol
