Abstract

This research was part of research  on manufacturing of fruit flavored instant coffee. The research was  intended to obtain mangoes powder which can be applied to small industries. Research using randomized complete design with concentration of fillers as the treatment with 3 replication. Mangoes used in this research were mangga harum manis and fillers used were sugar at a concentration of 20%, 25% and 30%. The physicochemical  all treatment have water content below 4%, and total plate count below 100 cfu. While the highest ascorbic acid content was obtained from 20% sugar namely 2,250±160 ppm . The level of consumer preferences were analyzed following the procedure organoleptic test by 12 panelists including color, aroma and taste. The highest score preference level of color was produced by 20% sugar that was equal to 3.5 ± 0.67; while the higest score for aroma and  taste by 25% sugar that was  equal to 3.4 ± 0.51; 3.9± 0.67 respectively.

Abstract

The research was intended to study the development of color during heat treatment in a model real system consisted of sucrose, sweetened condensed milk, egg and margarine. Research applied was factorialcompletely randomized design with steaming time consist of 1,2,3 and 4 hours and temperatures consist of 100oC, and 110oC as treatment with 3 replication. The changes of color was investigated by using Munsell color system consist of value/lightness, hue angle, and chroma. Browning index was measured by using the absorbance of ethanol extracts at 420 nm in 40.0 mm silica. Amino acid content was observed by using HPLC. Research showed that there were negative correlation between steaming time and temperature with lightness, hue angle, chroma, and amino acid. While for TCD, and browning index indicated positive correlation.

Abstract

The research objective was to determine a proper formulation in rubber compound processing by addition of jarak oil epoxy to make rubber washer compound the quality specification.The experimental design used in this study was Complete Randomized Design (CRD) with two replications and two factors. The first factor was the concentration of epoxidized castor oil (P1 : 3 phr, A2 : 2 phr and A3 : 3 phr). The tested parameters were hardness, elongation at break, abrasive resistance and flex resistance, The result showed that the addition castor oil and antioxidants and its interaction had significant effect on the elongation at break and abration resistance. The addition of epoxide castor oil gave insignificant effect on the hardness of the rubber compound. The best treatment was found at epoxy castor oil concentration of 3 phr and antioxidant of 3 phr having characteristic of rubber washer compound that consisted hardness 48 Shore A, elongation at break 2682%, abrasive Resistance 131 DIN mm and flex resistance : no flex.

Abstract

Laboratory waste water is categorized as a toxic and hazardous waste. Research on laboratory waste water treatment which is resulted from COD analysis by applying coagulation, filration, adsorption and ion exchange in one step intergrated method has been done, in a laboratory scale of 1 liter volume of laboratory waste water. The purpose of this research is to get the optimum condition of treatment by variation the kind and concentration of coagulant, and the contact time in the adsorption process. Percentage decrease of pollutant has been observed through the measurement of some parameters such as: Total Dissolved Solid (TDS); Heavy metals such as iron (Fe), Manganese (Mn), and chromium (Cr), ammoniac and acidity (pH). The resultof this research that the best coagulant was 1 g/L Alum sulphate (AL2(SO4)3) and contact time was 2,5-5 minute. The result of analysis integrated laboratory waste water had been treated with batch system able to reduced total dissolved solution (TDS) 78,61 – 91,23%. Heavy metals Fe 97,61% - 99,99%, Mn 45,53% - 99,88%, Cr 92,54% - 99,98% and ammoniac 22,54% - 91,82%. Acidity (pH) of final laboratory waste water was 8,93.

Natural starch can be made into modified starch with the desired properties or as needed. Composite of starch and natural rubber for the made of rubber sheets as an alternative to reduce the use of natural rubber in large quantities. The research aimed to study the characteristics of sheets rubber with composite modified starch - latex. The experimental research used non Factorial Completely Randomized Design and each treatments was replicated three times. Single factor of starch and latex modification ratio (Treatment A Starch modification: latex = 1: 1 (500 ml: 500 ml, Treatment B Starch modification:latex = 1:2 (500 ml: 1000 ml and Treatment C Starch modification:latex = 2:1 (1000 ml: 500 ml)). The parameters were plasticity (Po), plasticity resistance index (PRI), mooney viscosity and dirt content. Results showed that the comparison treatment of starch and latex modifications have a influence on the characteristics of sheet rubber meet the quality requirements of Standard Indonesian Rubber (SIR) 20 SNI 06-1903-2000 and standard quality commercial sheets rubber with charactheristics plasticity (Po), plasticity resistance index (PRI), mooney viscosity and dirt content.
