Publisher : Universitas Riau

Seed of picung (Pangium edule Reinw) contains 70 % kernel (weight) and 40 % husk (weight). Itsnucleus’s seeds contain 21-27 % oils that can be extracted. More than its 70 % component is an oil cake.The huge amount of oil cake can be used as a solid fuel such as Biomass Briket (Baiobriket). Biobriket hasweight 23,046 gram,long 3,469 cm, wide 2,804 cm and high 2,277 cm. Biobriket picung is produced bymanual process inlet dry materials that is pushed and pressed by hydroulic press. The pressing processproduces solid materials that will be piece into specific size. Picung oil cakes have a weakness as a solidfuel. It has no high heating value and its physic characteristic that has low binder. To increasing heatingvalue, glycerol is added. Because glycerol has a heating value equal to 1353 kcal/ kg. Glycerol can beused as an alternative heating resource. Binding problems can be solved by adding tapioca. Optimumadding of tapioca is not more than 5%. The final step of this research is found the comparison of qualitybetween optimal biobriket picung oil cake. This research used central composit design. The first factorwas quantity of glycerol (X1) and the second factor was quantity of tapioca (X2). Picung oil cake usedwas 200 gram. First factor’s range was between 1 – 5,5 % weight of oil seed or at 1,76-9,69 ml (densityglycerol was 1,13 g/ml). The seconds factor range was 1 – 5 % weight of oil cake or at 2-10 gram.Optimation response used was heating value (Y). Analysis with response surface method shows thataddition of glycerol had a positive influence to the heating value of biobriket with desirability 94 %. Theoptimum value for heating calor biobriket was 6243,62 kcal/kg.

The research objective was to determine optimum dosage of “mutiara” NPK (16:16:16) fertilizer and various type of mulch for chili plant yield. This research was conducted at experimental plot, Faculty of Agriculture, Riau University from September 2007 until January 2008. The experimental method used was Randomized Block Design in factorial. The first factor was level of NPK fertilizer (N) namely: without NPK (N0), 125 ton/ha NPK (N1), and 250 ton/ha NPK (N2). The second factor was various organic mulch (M) namely: oil palm empty fruit bunch (TKKS) 10 ton/ha (M1), paddy chaff 10 ton/ha (M2), and hay 10 ton/ha (M3). Parameters observed were harvest time, number of fruits per plant, weight of fruits per plant, and the percentage of consumable fruits. The result showed that supplying “mutiara” NPK (16:16:16) fertilizer dosage of 250 kg/ha together with rough rice bran mulch or TKKS gave better results than other treatments.

The study on growth production of paddy (Oryza sativa L.) Variety IR-64 in the peat soil given Dolomite andCopper (Cu) through leaves have been conducted at Simpang Baru Village Tampan, Pekanbaru City for 5bohths; starting from February to June 2003. The objective of the experiment was identity the effect ofbolomite and Copper given trough leaves and their interaction on the growth and pnKiuction of Rice in the peatisoil. The experiment was arranged in a randomized factorial block design with three replications. The firstfactor was various doses of Dolomite, that was KO (without Dolomite), K l (Dolomite of 0,5 ton/ha), K2 (Dolomiteof 1,0 ton/ha), K3 (Dolomite of 1,5 ton/ha), and K4 (Dolomite of 2,0 ton/ha). The second factor was various dosesof CuSO,, that was CO (without CuSO,), C I (CuSO, of 100 g/ha), C2 (CuSO^ of 200 g/Tta), C3 (CuSO, of 300g/lia), and C4 (CuSO, of 400 g/ha). Parameters observed were plant height, weight of drayed straw, number ofproductive samplings, percentage of well filled rice grain, weight of 1000 .seeds, weight of rice grain. Experi-ment result show tlrnt Dolomite could improve the growth and production of paddy rice and Chopper significantlyincreased weight of dried straw, percentage of well filled rice grain, weight of 1000 seeds and weight of ricegrain. The interaction between Dolomite and Copper significantly increased the weight of dried straw. Ricegrain production treated with 1,5 ton/ha Dolomite and CuSO^ 400 g/ha given trough leiives wiis 2,97 ton/ha.

The purpose of this research was to conduct physical optimation of chemical properties of rubber seed oilthat could be used as edible oil. This research was conducted by using the Complete Random Block Designconsists of 4 treatments with 3 replications. The treatments were duration of smoking, respectively 12, 16, 20and 24 hours. The data obtained then be analyzed statistically by using ANOVA. The Results of study showedthat duration of smoking a real effect (P <0.05) on yield and water content of rubber seed oil yield, whereastreatment did not affect significantly (P> 0.05) on acid, iodine, and peroxide values of oil and oil color.Based on the results it can be concluded that the duration of smoking for12 to 24 hours make the quality ofrubber seed oil was that oil not feasible as the cooking oil.Key Words: rubber seed, cooking oil, chemical properties

The effect of various fermentation times on the quality of dried Forastero cacao beans was evaluated. Dataobtained were treated by the analysts of variance followed by a least significant difference test Various fermen-tiition times significantly affected the total acids, weight of 100 of beans, number of mould-infected beans, andthe colour of cacao beans, however no effect of fermentation times on the fermentation index, p H , aroma andtaste of cocoa beans was observed. The higher quality of d ried Forastero cacao beans processed by use of Slnie-Cadbury method was found when raw beans were fermented for 5 d than for 3 or 7 d.

The aim of this study was to explore the processing of jamblang (Syzygium cumini) fruit into syrup. Moreover,the effect of water and fruit ratio, and sugar concentration on the characteristics of the syrup was investigated.This study was conducted using a completely randomized design factorial consisting of two factors: the ratioof water and fruit (2: 1, 1: 1, 1: 2) and the concentration of sugar (65%, 75%, 85%). The results showed thatthe best quality of the syrup based on organoleptic tests obtained from the treatment combination of waterand fruit ratio = 1: 1 with a sugar concentration of 65%. After pasteurization, the syrup had a pH value of3.89, total sugar of 88.70%, anthocyanin content of 29,73 mg/100 g, antioxidant activity of 58.74%, vitaminC content of 7,04 mg/100 ml and panelists liked its color, aroma and taste.

The experiment purpose was to evaluate the effect of Trichoderma spp. Substitution during composition process on the quality of resulted compos. Compos made from organic debris as the main component and fresh cow dung decomposer was used as the compos mass for the decomposition process. Pellets of three species of Trichoderm i.e T.Koningii (T1), T.reesei (T13) dan T.harzianum (T27) were substituted into the compos at 10th, 20th, 30th days during the decomposition of organic debris by containerizing the treated composes in nylon gauze container and inoculated into the compos mass. At the 70th day the compos were harvest and used as the component of medium to germinate pine seeds. The result show that application of T.koningii increased decomposition base on compos weight by 35,15%, which was lower than control treatment. Application of Trichoderma spp. At 10th day increased the quality of resulted compos compared to those at day 20 and day 30 by 31,09% and 62,18% respectively. Application of T.reesei at day 10 lowered the C-N ratio at the amount of 56,6%. T.koningii showed its biological control potiental at day 10 of application indicated by 60% increased of survival percentage.

The objectives of this study were to ascertain the effectiveness of Trichoderma spp. which was applied innurseries to control Ganoderma sp. in plantations of/I. mangium. Trichoderma spp. Isolates T „ and T „ inpellet form were applied in a ratio of five pellets to each A. mangium seedling, following w il h A. mangiumseedlings which were planted in the field. .At the ages of six months, the level of attack by Ganoderma sp. wascounted at sampling intensity of 100%, and soil samples were taken from around the planting with a samplingintensity of IQ'A in order to identify the presence of isolates T „ and T ^ as well as to identify the soil chemicalproperties. The results of identification through inacro.scopic and microscopic observation as well as dualculture tests, pointed back to isolates which appear to be T „ and T^j. In addition, results of the study showedthat for 6-month old A. mangium, the use of applications of T ^ tead to a tower level of attack by Ganoderma sp.in plantations of A. mangium (0.67%) compared to applications of T „ (1.17%) and the control (0.83%).Grow th of T „ isolate in SA medium up to the sixth day was better (65.49 cm') than that of T,j (36.35cni-).
