Abstract

Fruit leather type of food made from fruit that have been crushed and dried.  Fruit leather has a storage period of up to 12 mounth if kept in good storage conditions.  One of the criterationfordeterminan the quality of fruit leather is color.  The fruit used is not just the fruit of this kuini but combined with red dragon fruit to color interesting and also dragon fruit contain useful pigment.   This study aims to determine the best characteristic of the concentration of fruit kuini and red dragon fruit in the manufacture of quality fruit leather product.  Treatment used KN1 (50% kuini fruit, 50% red dragon fruit), KN2 (60% kuini fruit, 40% red dragon fruit), KN3 (70% kuini fruit, 30% red dragon fruit), KN4 (80% kuini fruit, 20% red dragon fruit), KN5 (90% kuini fruit, 10% red dragon fruit). The data obtained were analyzed statistically by using Anova and DNMRT at 5%.  The result showed that the use of kuini and red dragon fruit significantly affect the water content, ash content, acidity degree, coarse fiber content, sucrose content, and organic assessment. The best fruit leather the results of this study is fruit leather with KN3 treatment, which has a 12,08% of water content, 0,89% ash content, 4,40% acidity degree, 1,12% crude fiber content, 58,57% sucrose content.  Descriptive assessment shows the result that is the color is yellowish red, the aroma tends to smell the fruit of kuini and red dragon fruit, sweet taste, chewy texture and the hedonic overall assessment fruit leather favored by panelists. Keywords: fruit leather, kuini fruit, and red dragon fruit

Abstract

Increasing need of energy and decreasing of fuel supply requires human to discover alternative energy resources. Consequently, there should be a research to discover a new renewable energy source such as palm leaves waste. Oil palm’s leaves (Elaeis guineensis Jacq.) are mostly the least used waste from oil palm plantation as an alternative energy resources. This research aims to discover the precise adhesive consentration rate in sago’s starch (Metroxylon sago Rott.) to make oil palm’s kernel, which are 97%:3%, 96%:4%, 95%:5%, 94%:6%, and 93%:7%. Based on analitycal result of oil palm’s leaves charcoal briquet research, the best quality briquet is the P1 composition which composed rate is 97%:3%, has 3,21% water content, 30,18% ashes content, 0,0022 g/s combustion rate, 20,73% evaporated substance rate, 54,46% carbon rate, and 5.114 cal/g heat value.  Keywords : briquet, oil palm’s leaves, sago starch adhesive.

Abstract

The aim ofthis research weretreatment withconcentration of citric acid and soaking time on quality dried sweetened pineapple core. A complete random design with two factors and three replications was applied in this research. The first factor wascitric acid concentration 0.1%, 0.15% and 0.2% and second factor is soaking time 36 hours, 45 hours and 54 hours. The design response was usedDuncan’s New Multiple Range Test (DNMRT) the level 5%. Parameters observed were the evaluation sensory of description and hedonic (colour, flavor, taste, texture and overall assessment). Treatment with concentration of citric acid and soaking time have an effects to evaluation sensory of description and hedonic on colour, flavor, tastebut not have an effect totexture and overall assessment. The best treatment of dried sweetened pineapple core was obtained 0.15% concentration of citric acid and 12 hours soaking time with color is dark yellow (score 2.53) and preferred (score 4.10), flavorful pineapple (score 4.26) and preferred (score 4.21), quite sweet and sour of taste (score 3.53) and preferred (skor 4.21), hard textured (score 2.40) and quite like (score 3.26) and overall assesment is preferred (score 4.32). Keywords:citric acid, soaking time, pineapple core, dried sweetened

This study used a completely randomized design with 5 treatments and 3 replications. The treatments used were herbal tea fragrant pandan leaves are P1 (drying 110 minutes), P2(drying 130 minutes), P3 (drying 150 minutes), P4 (drying 170 minutes) and P5 (drying 190 minutes). Data were analyzed statistically using ANOVA and DNMRT at 5% level. The results showed that the drying time significantly affected the moisture content, ash content, antioxidant activity and sensory assessment (descriptive and hedonic). The treatment chosen from the results of this research was the treatment P3(Drying 150 minutes). Treatment of P3 had a water content of 5,17%, ash content of 3,30% and antioxidant activity (IC50) of  5,68 ppm. Rate sensory descriptive and hedonic herbal tea fragrant pandan leaves treatment P3 had the colour of powdered tea that was green and the colour of brewed tea was a little green, the aroma of tea powder was scented fragrant pandan leaves and the aroma was brewed tea wasa little scented fragrant pandan leaves, taste steeping tea was a little astringent. The overall assessment of herbal tea steeping fragrant pandan leaves was slightly favored and tea powder was too slightly favored by the panelists. Keywords: herbal tea, pandan fragrance, antioxidant activity and drying time.

Abstract

Rubber can be used as a source of wood raw materials for various uses such as wood fanel, pulp and paper products, furniture and other processed wood products. The aim of the research was to get the characteristic part of rubber stem physical of  non-productive rubber stem in the base, middle, and of the tree end. The experiment was conducted using experimental method using Completely Randomized Design (CRD) which consisted of three treatments and five replications to obtain 15 experimental units and continued with Duncan's New Multiple Range Test (DNMRT) test at 5% level. The treatments in this study included rubber stem at the base (K1), rubber stem in the middle (K2) and rubber stem at the end (K3). The results of variance analysis showed that the treatment at the base, middle, and rubber stem ends significantly affected the specific gravity of wood produced from rubber stem ranging from 0.779 to 0.606 kg/cm3. Wood water content generated from rubber stem ranged from 5.306 to 7.485%. Shrinkage of radial wood resulting from rubber stem ranged from 4.327 to 5.681%, and the tangential depreciation resulting from the rubber stem ranged from 4.685 to 5.813%.                                                         Keywords: rubber stem, physical properties, wood raw materials
