Small industry is one important component in national economic structure, because it can absorb a lot of manpower and a lot of exploiting the potential of natural resources abundant in Indonesia. The number of small industries in Indonesia is quite a lot, but has not been matched by much higher performance. Therefore the number of small industries which are so muchslower average growth and is difficult to compete with large industrial products and imported products. Industry performance is one of the criteria used to measure industry growth. With performance measurement-performance small industry and handicraft villages can be foundin different areas of industry map homeland. During the performance measurement industry is based only on financial aspects. Performance measurement of the financial aspect is important, but still there are other aspects that are also important and need attention because theyaffect the performance of the industry, namely: aspects of customer (market), internal business processes and learning and growth. Therefore it is necessary for measuring the performance of various aspects of small scale industries so that their performance can be evaluated and formulated a model maintenance and development of small industries and handicraft villages are more comprehensive. The method used is the Balanced Scorecard (BSC) and Analytical Hierarchy Process (AHP). The Balanced Scorecard measures the performance of the business / industry with 4 perspective, financial, customer, business process within the company, and the process of learning and growth. Method of Analytical Hierarchy Process (AHP) is used to embobot each perspective and each Critical Success Factor. Research results showed that the average performance of small industries in Trowulan Pasuruan Stone Statue of 2083 (category enough). There are 2 perspectives of a very large weight on the performance of a stone statue of a small industry of financial and customer.

Published: August 2017

In the world of industry, insulation materials are often utilized to maintain the temperature, either low or high. However, since the insulation materials often need to be thick, thus, costly, they are frequently deemed impractical. Therefore, in the attempt to replace the insulation materials, a cavity with low vacuum pressure is opted for. Yet, to attain a total (100%) airfree cavity is not an easy task. Such, the cavity usually still bears some amount of air pressure which results in natural heat convection through the two surfaces making up the cavity. The transfer coefficient of natural heat convection (h) is influenced by some factors, such as, the temperature difference, geometry of the cavity, cavity orientation, and characteristics of the fluid, for instance, its pressure, temperature, conductivity, specific gravity (density), and viscosity. The purpose of the study is to find answers to the following question: “How do vacuum pressure variation and cavity ratio affect the rate of natural heat convection through the a cavity?” Pertinent to the question, the study was aimed to find the appropriate value of the vacuum pressurewhich can function well as an insulator. This study is significant in the attempt to lower down the rate of heat transfer taking place in a system vis-à-vis the surrounding media. The study found out that the degree of emptiness of -60 cm Hg and =5.96, results in a lower rate of heat transfer compared with -20 cm Hg and -40 cm Hg. This means that the vacuum pressure of -60cm Hg bears a bigger thermal resistance than the -20 cm Hg and -40 cm Hg do.
