Abstract

Companies that are categorized as small industries face many difficulties to keep survive or to develop their products. The subject of this study was convection home industry with the commodity as follows: Muslim clothes, sport shirt, baby clothes, children clothes, bed covers, veils, and many kinds of embroidery products. The purpose of CSSF (Contingent Strategic Success Formula) approach was to analyze the formula of success strategy by combining the internal condition with external condition of the company. The ways to do that were by measuring, estimating, and predicting the environment condition of the company at this time and at the specific time in the future. The measuring of internal condition of the company is aimed to know the things that need to be repaired so the company can fulfill the requirement of optimal external condition in the future. The finding of this study was shown in 4 cases. First, the variables that have influence in convection home industry were 36 industries. Second, there were 3 clusters of convection home industries, those were: Cluster 1, the companies of embroidery convection that lack of success, and Cluster 2 and 3, the company with mass production that success enough and very success. Cluster 1 was categorized as the company that left behind in the competition and its agresivieness and responssiveness is under environment turbulence. Cluster 2 was success enough because the turbulence difference with agresiveness and responssiveness is not wide. Cluster 3 was the best one because the company was number one in the competition and its agresiveness and resposiveness exceed the environment turbulence at this time. Three, to get success in the future, the company need to fulfill the optimal internal condition that suitable with the level of turbulency. It is better for the companies to apply 3 succeed marketing points, those are: to develop the positioning of the products in the specific SBA, create the strong differences, create mark equities, or the emotional relationship with the customers

Abstract

Noise is a longitudinal wave which is known as pressure wave. Therefore, noise is expected to disturb the stability of fluid flow. The disturbance is expected to increase the heat transfer of fluid flow. In this research, noise was applied to condenser cooling of air in a refrigeration system. Effect generated is directly measured by amount of heat capable to be released into the air passing condenser, and indirectly by the compressor energy required and coefficient of performance (COP) of refrigeration system. Experimental results indicate that noise with intensity level of 115 dB with frequency around 100–500 Hz at air velocity of 5,3 m / s increases the amount of heat capable to be released into the air which is 10,1%, reduces compressor energy to 12,8% and increases coefficient of performance (COP) by 11,4% compared to flow without noise.

Abstract

Patchouli oil is an excellent of the Indonesian essential oil, because 45% of essential oil government-reserve is gained from it. Patchouli oil is commonly used in soap industrial, hair tonic, mouthwash, and high quality perfume. In the utilizing, patchouli oil is mixed with other essential oil, such as: clove oil, rose oil, and vetiver oil; since the fixative nature with flavor substance could chain the other essential oil. The fixative nature and the odor resistance come from the tertier alcohol substance, e.i.: patchoulic alcohol as its main component. Although it has long odor resistance, as an aroma substance, the odor of patchouli oil has less strong. As the base character of aroma substances determined by ester component compiler, so it is interesting to study the esterification reaction controlling the amount of ester product. In this research, patchouli oil was converted into the ester substance by esterification reaction using anhydride acid and ZnCl2 catalyst. The esterification was optimized to various concentration of ZnCl2 catalyst from 1–5% and to obtained the most preferred ester dan patchoulic alcohol ratio. Characterization of trade patchouli oil and the product of esterification were conducted based on determining the physical nature, such as: density and refraction index, and also the patchouli oil component's profile from chromatogram and mass spectrum resulted from GC and GC-MS analysis. To know most preferred ester and pachoulic alcohol ratio, using hedonic test with 25 panelists was conducted. The research resulted that the esterification reaction of patchouli oil using anhydride acid could be done by using ZnCl2 catalyst. Characterization result using GC indicated that the component's profile change under esterification condition; while characterization result using GC-MS showed the existence of patchoulic acetate substance. Variation of anhydride acid composition affected the ratio profile of patchoulic acetate and patchoulic alcohol. Hedonic test results showed that panelists'most preferred ratio of patchoulic acetate and patchoulic alcohol is 0.7934.
