Improving the efficiency of production and quality of products is possible only with the organization of modern metrological support. The paper presents measures and tasks concerning metrological support of production at the stages of design, development, production and testing, contributing to the production of quality products. To fulfill the tasks assigned to the metrological service, it must have a position, structure, quality assurance system, personnel, necessary premises, conditions for the operation and storage of measuring instruments.

<p>Measurement, Standardization, Testing and Quality Assurance (MSTQ) have important role in the recent development of industry, science and technology. Those four elements are interrelated, thus are measurement<br />without the accepted standard developed through National Standardization System is meaningless. Recently, most of calibration activities are carried out by private sector and their location are concentrated in Jakarta and<br />West Java. Most of them are focusing their calibration activities to the needs of their parent organizations, and the only small number of them also provides their calibration services to external customers. On the other hand, the number of testing laboratories increase faster as demand from the government for exported or imported products shall be tested by accredited testing laboratories as the application of mandatory national standards (SNI). Location testing laboratories widely spread in the country and their activities depend on the commodities of the region, for example, in the region those produce tea or coffee, there will be testing laboratories for tea and coffee. Scope of activities of calibration laboratories also focused on the measurement of mass, temperature, dimensional as most of Indonesian industries use the kind of measuring instruments for their processes.</p>

Small and Medium Enterprises (SME’s) in Tasikmalaya District are still managed traditionally. SME’s has not implemented a standard process so that the final product has various qualities. This activity aims to provide training on brown sugar quality assurance, Good Manufacturing Processes (GMP), sanitation, as well as good practice of brown sugar making and the use of measuring tools to standardize the process. The training was carried out for five days in Sariwangi District, Tasikmalaya Regency with the target of 20 sugar entrepreneurs from 4 districts, namely Sariwangi, Culamega, Puspahiang, and Curug Gambir. The results showed that all participants did not yet have production facilities that met the GMP requirements, did not understand the meaning of quality assurance and the use of measuring instruments that supported the improvement of the quality of brown sugar. The post-test results showed an increase in the awareness of SMEs about quality assurance of brown sugar, as indicated by the rise in the test score from 31.39 to 49.72. Process improvements include improving the sap filtering, crystallization, and adding egg white to bind the impurities. The quality of post-training products has improved, especially in terms of cleanliness and brighter colors.

The PZT according to MARKOWITZ, undoubtedly one of the most accurate measuring instruments, has become an integral part of astronomy in the last years. Yet there are two reasons why I still tried to improve the MARKOWITZ basic idea.For the MARKOWITZ process the use of a lens objective is imperative. Because of the diameter limitations of the lens objectives the magnitude is reduced. Although a 65 cm PZT has been put into operation in Washington recently, the thermal difficulties encountered made it necessary to control the temperature actively. In addition, the 65 cm diameter of a lens equipped with 4 elements can be considered as the very limit, but not for a mirror system.In addition there are still more disadvantages using lens objectives. The useable field is restricted by astigmatism, reducing the range of declination. The transmission, especially in the blue wavelengths, decreases very rapidly with the thickness of lenses. For large multilens objectives the transmission is less than for a mirror system.
