Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Exploration is one of the activities of the mining process which aims to obtain information about the geological conditions of a deposit that is below the surface of the land. Exploration activities have risks and require a large cost. Therefore, a more accurate estimation method is needed in determining the value of areas that are not sampled in exploration based on the surrounding data. In coal deposits, there are two main output parameters which are coal thickness and quality. In this study, the coal quality parameters used are calorific and sulfur values. In this study, we will compare the Kriging method with Inverse Distance Weighting, in estimating coal thickness and quality. The aim is to find out the most accurate estimation of coal thickness and quality between the Kriging and IDW methods based on the Root Mean Square Error (RMSE) value. The method of testing the estimation results is cross validation. The choice of the variogram model is based on the lowest RMSE value. The research method used is a quantitative method. Coal exploration data in the form of bar data were analyzed with descriptive statistics with Minitab 17 software and continued with geostatistical analysis using GS + software. From the results of the calculation of the two estimation methods, it was found that the kriging method was more accurate than the IDW method based on the lower RMSE Kriging value on the thickness data, calorific value and coal sulfur worth 1,622 m, 71,504 Kcal / Kg, and 0.140% compared to the IDW method RMSE on coal thickness, calorific value, and sulfur data are 1,704 m, 74,731 Kcal / Kg, and 0.142%
Regeneration of local cultural heritage is one way to strengthen the uniqueness and identity of the city in the era of globalization, that frequently seen as a threat to the existence of city identity. It is a very relevant issue for the corridor of Jalan Masjid Jamik, as a part of the historic downtown area in the city of Pangkalpinang. Hence, the purpose of this study is to investigate the phenomenon of local character transformation in the corridor of Jalan Masjid Jamik. In this descriptive study, the identification and classification of architectural style of the facade elements of 62 buildings, as the research sample, was conducted by the author objectively and by subjective confirmation from the building owner. The results of the study exhibited that the city corridor of Jalan Masjid Jamik still has a strong Malay identity or character, because buildings with Malay architectural facade designs were observed predominantly. This local character appears alongside the global character dominated by Art Deco and Modern architectural style. The scale of trading and services conducted is one of the factors affecting the transformation of local character in the study area
