Paradigm Shift in GNSS Education for Asia Pacific Nations
Azmi Hassan,Mustafa Din Subari 한국항해항만학회 2006 한국항해항만학회 학술대회논문집 Vol.2 No.-
This paper identifies GNSS education and training program under Geomatic field of study. GNSS education programs is evaluated vis-à-vis new-products. Data on Geomatic knowledge generation in the era of the GNSS derivatives over the 1975-2003 period are examined. The emerging trends and patterns; in particular for selected Asian nations will be dissected in detail. The knowledge indicator used in this study is the patent ownership against the background of emergence of new core technologies and innovations in the field of GNSS. Looking at the dismal performance of Geomatic professionals in terms of innovative activities in most part of Asian and Malaysia in particular, is it there is something that holding up these professionals from doing so? With our universities and numerous polytechnics offering Geomatic program, more is expected from them. Is it a problem of lack or inadequacy of skills? Or is it these professionals are too busy and being narrowly focused on doing something else?

The modern electrical industry in Indonesia faces escalating energy demands, projected to reach 1,413 Terawatt Hours by2060. Meeting these demands necessitates enhancing the quality of electrical transmission systems, particularly insulators, witha focus on local materials to reduce dependency on imports. Porcelain Alumina Ceramic Insulators (PACI) offer promisingalternatives due to their high resistivity and mechanical strength. This study investigates PACI synthesis using locally sourcedmaterials: kaolin, ball clay, alumina, and feldspar. Chemical analysis confirms alumina as the primary component (99.7%Al2O3), while other materials contribute to silica content. Fabrication involves crushing, drying, grinding, sieving, and sinteringat 1280 °C, yielding specimens (K1S, K2S, K3S). Material characterization employs XRD, XRF, SEM and electrical testsreveals phase compositions, morphological changes, and electrical properties. K3S, rich in feldspar, exhibits superior materialstrength (74.62 N/mm²) and hardness (190 N/mm²) with limited conductivity. Utilizing local resources for PACI productionpromises economic benefits and reduces import dependence. This study illuminates the interplay between material compositionand resulting properties, offering insights into ceramic synthesis for improved electrical infrastructure.
