Effectiveness of Similitude Theory for Bucket Design and Analysis for Rubber Tire Loaders

In this article, thermal performance of different waste materials and by-products of industrial processes is investigated experimentally. A geopolymer concrete block with 7.5 cm thickness and cross-sectional area of 5 × 5 cm was considered as a reference model to measure heat transmission across the two opposite surfaces while all four remnant surfaces were perfectly insulated. For all other samples, a sandwich concrete block was developed by taking two pieces of the geopolymer concrete with 2.5 cm thickness each on either side and insulation material of 2.5 cm thickness in between. The sandwich materials investigated were air cavity, expanded polystyrene foam, polyurethane foam, rubber tire, date palm, PCM-30, and PCM-42. Experimental investigations revealed that the investigated green materials and industrial by-products have comparable insulation performance with respect to the traditional insulations such as expanded polystyrene foam. It is found that polyurethane foam and date palm can reduce indoor cooling demand by 46.6% each in hot conditions while rubber tire can reduce indoor heating demand by 59.2% in cold climatic conditions at the maximum. The research results confirm and encourage the effective utilization of waste materials in building walls for reducing indoor air-conditioning demand in the extreme climatic conditions.

The tire industry is an industry that has potential to increase Indonesian exports to non-traditional markets such as Latin America. The purpose of the study is to analyze the power of the comparative, competitive, and export dynamic of Indonesian tire and also the factors that affect the export of Indonesian tire to Latin America. The period of analysis used in this study is from 2009 to 2014 using the method of analysis are Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), Gravity models and Porter's Diamond. The results of this study are rubber tire Indonesia has strong competitiveness in Latin America than in the country of Argentina. In addition, the rubber tire Indonesia has a good export dynamics position (rising star) in the country of Panama, Venezuela, Uruguay, Mexico, Guatemala, and Costa Rica. Factors that affect the export of Indonesian rubber tire to Latin America is the distance economies, Indonesia's per capita real GDP, real GDP per capita of the destination country, the real exchange rate, and the population of the destination country.Keywords: Competitiveness, Gravity Model, Porter’s Diamond,Tire
