Abstract

This research carried to obtain the best ratio of red dragon fruit peel and pedada fruit extracts in the manufacture of jelly candy. The research used a Complete Randomized (CRD) with five treatments and four replications which were followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatments in this research were PN1(ratio of red dragon fruit peel and pedada fruit extracts 90:10), PN2 (ratio of red dragon fruit peel and pedada fruit extracts 80:20), PN3 (ratio of red dragon fruit peel and pedada fruit extracts 70:30), PN4 (ratio of red dragon fruit peel and pedada fruit extracts 60:40), PN5 (ratio of red dragon fruit peel and pedada fruit extracts 50:50).  The result of analysis showed that the ratio of red dragon fruit peel and pedada fruit extracts significantly effect on moisture content, ash content, fiber content, reduce sugar and colour but did not significantly  effect of taste, texture and overall assesment of jelly candy. The best formulation jellycandy was PN4 with water content 7.52%; ash content 2.02%; fiber content 1.60% and reduce sugar content 20.48%. Organoleptic scores of PN4 were 2.37 (red); 3.07 (sweet little sour); 3.46 (netral flavour); 3.93 (chewy) and 3.70 (overall) assesment of jelly candy.  Keyword:Jelly candy, red dragon fruit peel and pedada fruit.

Abstract

The amount of waste generated logging plantation forests (HTI) come to the surface environmental impacts, whereas the waste can still function to use and processed into smoke liquid. Smoke liquid products was made from logging waste (HTI) can be used as an alternative to artificial fertilizers or chemicals. The purpose of this study was to evaluate the response of the acacia plants growth by administering smoke liquid. The benefits of this research is to develop the use of smoke liquid as a natural liquid fertilizers, find how to use smoke liquid as a natural fertilizers for the public plant acacia. Increase the economic value and was usability of waste industrial timber estates (HTI). This study uses a was completely randomized design (RAL) with 4 treatments 3 replications, in order to obtain 120 units of plants with each trial consisted of 10 plants. Results from the study can be showed that administration of smoke liquid affect the growth of plants Acacia mangium Willd. Treatment with a dose of smoke liquid 5 ml / 1 L of the water shows the most optimal response to plant growth compared to treatment with a dose of smoke  liquid 1 ml / 1 L of the water and 3 ml / 1 L of water. Giving liquid smoke on the best dose may increase as height, diameter and dry weight of seedlings Acacia mangium Willd. Keywords: Acacia mangium, Utilization, Smoke liquid, Waste industrial  forest plantations (HTI)

Abstract

This research can be done in the frequency of the pruning of water shoots and the concentration of liquid supplementary fertilizer and the best combination in improving growth and yield of cayenne pepper. The experimental method was conducted experiments in the form of a 4 x 4 factorial experiment arranged according to Complete Randomized Design. The first factor is the pruning of water shoots. The second factor of liquid supplementary fertilizer given in the form of Bayfolan. The data those collected analyze with Anova and Duncan’s new Multiple Range Test at the 5% level. Parameters observed were plant height, stem diameter, first flower appeared, the age of the first harvest, length of fruit, fruit diameter, weight per fruit, total fruit count per plant and weight of fruit per plant. The frequency of pruning of water shoots has no effect on all parameters, except for total fruit per plant. The frequency of pruning of water shoots 1 time indicates the total fruit count per plant more than the frequency of pruning of adventive shoots. PPC concentration has no effect on all parameters, except for the length of the fruit. A PPC concentration of 3 cc/l water indicates the length of the fruit is longer than the other PPC concentration. The interaction of frequency of pruning of adventive shoots and PPC concentration has no effect on all parameters. Keywords: Cayenne pepper, pruning of water shoots, liquid supplementary fertilizer

Abstract

Rubber seed is not utilized optimally nowdays. One alternative to utilize the rubber seed is using it’s oil as cooking oil. This research was aimed to obtain optimal heating temperature variation on the cyanide acid content and the quality of cooking oil produced. This research was conducted by using Completely Randomized Design (CRD) experiment with five treatmens and three replications which followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatmens in this research were P1 (70°C for 4 hours), P2 (temperature 80°C for 4 hours), P3 (temperature 90°C for 4 hours), P4 (100°C for 4 hours). The results of variance analysis show that the higher the heating temperature significantly decreased the average content of cyanide, acid value, density and moisture content but increased saponification value. Based on the results obtained, the best treatment in the rubber seed heating was P4 treatment (100°C for 4 hours) with cyanide acid content 1,42 ppm, acid value 1,38 mg KOH/g, saponification value 161,64 mg KOH/g, density 0,864 g/ml and moisture content 0,912 %.  Keywords: Heating temperature, rubber seed, cyanide acid, cooking oil.

Abstract

Forest has such great benefits for life. Various tangible and intangible benefit that can be obtained from the forest can also be optained from the arboretum. Although basicly arboretum serves as a means of education. Tangible and intangible benefits that could potentially be produced is still rate as low, causing excessive exploitation. Assessment the benefits of trees on a place at the price of economic value necessary to considen improve the bargaining position and transforming into economic value of money. The presence of trees also affect the micro climate (value coolness) around the arboretum. Becomes a problem when the arboretum was damaged because it was not able to provide coolness around the arboretum. The research was conducted in the arboretum area of Riau University Pekanbaru on December 2015. The purpose of this research was to determine the economic value of trees in the arboretum area of Riau University and determine the economic value of the coolness in the arboretum area of Riau University. The research result showed that the economic value of wood in Riau University arboretum is Rp. 951.852.785,54 and the economic value of coolness in Riau University arboretum is Rp 23.875.000.000.Keywords:Economic valuation of wood, the coolness, arboretum

Abstract

Jackfruit seeds and skim milk fermented by Lactobacillus casei subsp. casei R-68  expected to produce fermented milk that has more complete nutritional value and  health benefits. Lactobacillus casei subsp. casei R-68 was isolated from dadih, a type of fermented milk in West Sumatra, Indonesia. This study used Completely Randomized Design experiment with 6 treatments and 3 replications to obtain 18 experimental units. The data obtained were statistically analyzed using Analysis of Variance (ANOVA). If F count is greater than or equal to F table then it continued with DNMRT test at 5% level. The results showed that pH of jackfruit seed fermented milk were 4,83-5,80, total lactic acid 0,52-1,17%, total solids 10.15-25.40%, protein content 23.76-6.16% and ash content 0.08-1.07% after fermentation.While descriptive assessment of which felt a bit acidic, yellowish white to white and its viscosity was dilute to thick and favored by panelists.Keywords: Jackfruit seeds, Lactobacillus casei subsp. casei R-68 and skim milk.
