Abstract

This study aims to gain influence the thickness and concentration variations affect the characteristics of sago binder physical properties of catfish jerky. As well as getting influence the thickness and concentration variations affect the level of binder sago joy panelists in terms of organoleptic test. Data were analyzed by analysis of variance using the Analysis Of Variance (ANOVA). If there is a significant difference followed by a further test of DMRT 5% level (physical properties). While the hedonic test performed using Kruskal Wallis analysis. Results uniformity analysis (ANOVA) showed catfish fillet thickness and concentration of sago affect the physical properties of the water content and the level of violence. Where catfish jerky using sago binder 5% and 10% significantly different. The use of sago binder 5% and 10% led to an increase in water content. Besides the addition of the binder resulted in increasing levels of violence catfish jerky. Based on the statistics found that the influence of the thickness and concentration of the binder sago aroma, flavor and color of the sixth jerky catfish were not significantly different. But the texture was significantly different.

Abstract

PTPN VII (Persero) Pagaralam Business Unitstarted developing the processing of black tea (CTC). Only after several times the processing quality CTC teas produced unsatisfactory. The Company continues to optimize the performance ofthe processingand quality control of CTC tea. This study aims to determine the effect of the quality of shootsandwilting percentage of the physical and organoleptic properties of CTC tea. This research was conducted in PTPN VII (Persero) Act Pagaralam. The results showed that all of the top quality withvalue range 62% to 70% and the percentage of wilted 65% to 72% no real effect on the physical and organoleptic properties. The water content and density of CTC tea has fulfilled SNI and enterprise standards. CTC tea produced medium quality (Fair made).

Abstract

Oil is one of the important basic material in the process of frying and it is functioned as heat transfer media.  During a process of frying, oil is experiencing quality declaining to be marked by forming free fatty acid and peroxides as the result of oxidation or triglyceride hydrolysis. This research aimed to determine the limit of usage and study on the quality change of oil used to fry nila fish repeatedly.  Process of frying was done by applying two methods; with new oil added and with no oil added during the process of frying. Parameters observed were the free fatty acid (ffa), smoke point, refraction index, and viscocity. Result of the research showed that both method of  frying could be repeated up to ten continues process of frying to have the oil quality within the standard  limit of deterioration. At the tenth process of frying, for both method of frying, the ffas  of  the used oils were 0.5 % and 0.3 % that were lower then the standar  ( 0.9132 %); the points of smoke were 200°C and 203.33°C  compare to the standar  (170°C); the viskositis were 15.29191 Cp and 15.07 Cp that were less than the standar  (21.6 Cp); and the refraction indexes were 0.81 and 0.96 that were lower than the standar  of  oil deteriorated (1.46).Keywords:

Abstract

Used refined cooking oil can be used to make soap. An important factor in the manufacture of soap is the saponification reaction between bases (KOH) and fatty acids. The addition of citrus essential oil to the soap preparation can increase consumer acceptance. This study aims to determine the effect of KOH concentration on the characteristics of liquid soap and to determine the proper concentration of KOH to produce good quality of liquid soap. This research uses a factorial completely randomized design with one factor that is KOH concentration, consisting of three levels ie 25%, 30% and 35%. Characteristics of liquid soap observed were viscosity, foam height, pH, and free alkali content. The results showed that the concentration of KOH effect on the characteristics of  liquid  soap  produced. If  KOH concentration increases,  viscosity,  pH and alkali-free  alkali content of the liquid soap increased. The best KOH concentration is 25%.
