Abstract

The research aims to study the response of seed germination and seedling growth of pine(Pinus merkusii jung et de vriese) with the application of solution concentration and dipping timeabitonik conducted in South Pujon seedbed RPH, BPKH Pujon, KPH Malang. The experimentbegan in September 2008 until May 2009.The research method used was a factorial experiment with Randomized Block Design (RBD),consisting of two factors, namely the first factor and second factor soaking Abitonik growth regulatorconcentration. Factor I: Long soaking, consists of three levels: P1 = Old soaking 20 minutes, P2 =Length of 40 minutes of immersion, submersion Old P3 = 60 minutes or 1 hour, Factor II:Concentration of growth regulators Abitonik, K1 = Concentration of solution 0, 04 cc / liter ofwater., K2 = concentration of solution 0.06 cc / liter of water., K3 = concentration of solution 0.08cc / liter of water, K4 = Concentration of solution 0.1 cc / liter of water.The research data from each observation parameters were analyzed by variance in accordancewith the randomized block design (RBD), the analysis was tested by using F test with a level of 5%.To compare among the treatments with one another treatment used Duncan’s test at 5% level.There is interaction between soaking time and concentration of growth regulators on theparameter Abitonik high seedling age 26 and 31 days after planting, total seedling leaf age 21 daysafter planting, and germination value. While the concentration of growth regulators Abitonik notprovide significant effect on germination of seeds Phinus. Parameters perlakuanlama germinationpercentage at 60 minutes of immersion (P3) of 59.73% and the concentration of 0.1 cc / l water (K4)of 59.22%.

Abstract

DNA based RAPD (random amplified polymorphic DNA) markers have been used extensivelyto study genetic relationships in a number of fruit crops. A wide genetic diversity exists in theJatropha curcas in Indonesia. Three accession of Jatropha curcas were selected to assess geneticrelatedness. Total genomic DNA were extracted and subjected to RAPD analysis using 10 primers.Of these, 27 primers ampified Jetropha curcas genomic DNA . Cluster analysis clearly showed twogroups, the first consisting ..... Jatropha curcas and th second groups consisting ..................

Abstract

The purpose of this research is to know the effect of calcium addition on foods to frequency offreshwater lobster (Cherax quadricarinatus) moulting. This research has been done during 30 daysin Fisheries Indoor Laboratory, Faculty of Animal Husbandry and Fisheries, University ofMuhammadiyah Malang.Result of research shows that calcium addition on foods success to increase frequency offreshwater lobster moulting. It shown by treathment B (2%) which has highest moulting frequency1,47. Then followed by treathment D (6%) = 1,40, treathment A (0%) = 1,27, and treathment C (4%)= 1,13. Calcium addition on foods also give positive effect to survival rate and growth of freshwaterlobster. All of treathments were added by calcium show that they have higher survival rate valuethan other treathments were not by added calcium. The sequential data of the average of freshwaterlobster survival rate are treathment B (2%) = 93,33%, D (6%) = 93,33%, C (4%) = 86,67%, dan A(0%) = 80 %. Whereas the sequential data of average to growth of freshwater lobster are treathmentB (2%) = 0,85 g, D (6%) = 0,79 g, C (4%) = 0,78 g, dan A (0%) = 0,73 g.

Abstract

TAsphalt concrete mix is one type of flexible pavement layer. Asphalt concrete mixture consistsessentially of coarse aggregate, fine aggregate, filler and binder. Aggregate used may be natural orthe result of processing and can also be the artificial aggregate. While grading for asphalt concretemix is Continuously graded. This study aimed to assess the absolute density, ie density of a pavementlayer maximum value. Absolute density is needed in order to predict the quality of road pavementlayers in accordance with the variation of the number of collisions 2x75, 2x150, 2x200, 2x300 and2x400 blows. Then studied the effect of variations in the collision of the Marshall test parameters,which include density, stability, voids of mineral aggregate (VMA), voids filled with asphalt (VFWA),voids in the mix (VITM), flow and marshall qoutient. The results showed a variation of the effect ofcollisions on the value of VITM. specially for heavy traffic comparison of values obtained onvariation of the collision VITM 2x150, 2x200, 2x300 and 2x400 to VITM standard is between 50-60% (collision 2x75). These results indicate that all kinds of variations of the collision above thestandard collision will result in fatigue of materials, pavement materials become damaged as aresult. From the results of this study also obtained the optimum asphalt content for heavy traffic,moderate and mild, respectively, are 6.44%, 6.59% and 6.86%. From the results of this study alsoobtained a density value of the field whose value is based on the optimum asphalt content in successionto heavy traffic, medium and light, which is 2.35 g / cc, 2.35 g / cc and 2.36 gr/cc

Abstract

Metalurgi powder is a commercial workpiece forming process of metal where the metal wasdestroyed first in the form of flour, then flour is pressed in the mold (mold) and heated below themelting temperature of the workpiece to form dust. So that the metal particles fuse because themechanism of mass transport due to diffusion of atoms between the particle surface. Powdermetallurgy method provides a rigorous control on the composition and use of mixtures that can notbe fabricated by other processesIn this study the process of soft magnetic iron production by mechanical alloying powderprocess-based yan metalurgy local iron sand. Base backdrop that the use of local sand from the datawe can from the foundry industry raw materials and large penunjangsebagian still imported. Materialsthat are 100% pengadaanya still relies imported materials are iron ore and alloys (Alloy).Iron filings and sand powder 100 mesh size locally has mixed for 20 minutes. The amount ofpowder added is 25%, 50%, and 75% by weight. Powder which had sifted and mixed and theninserted into molds (dies) that has been coated by the lubricant of zinc stearate on the walls of themold then dikompaksi both single-action pressing with a pressure of 2000 psi in order to obtain asample form of tablets.
