Abstract

The presence of archaeological sites, specifically caves, in North Konawe Regency provides evidence of human habitation dating back to prehistoric times. Despite the challenges posed by difficult terrain and limited access, which hinder archaeological research, the Gua Ladori site in Bendewuta Village, Oheo District, North Konawe, is notable for its rich assemblage of artifacts. This study aims to identify the archaeological remains at Gua Ladori and assess their significance within the prehistoric context of Sulawesi, with a particular focus on North Konawe. The research methodology involves three stages: data collection, data processing and analysis, and conclusion drawing. The findings reveal a diverse array of artifacts, including bone fragments, ceramics (earthenware, stoneware, and porcelain), stone tools, shell remains, and rock art. Analysis indicates that the earthenware and porcelain ceramics are likely from the 14th to 17th centuries AD

Abstract

As global technology and industry continue to develop rapidly, the manufacturing industry in Indonesia is also becoming increasingly advanced to keep pace with global industrial progress. A good surface metal is one that is clean from all types of contaminants such as dust, rust, oil, paint, and has a uniform surface roughness. Sandblasting is a method used to remove rust, dirt, and other impurities like oil and paint from metal surfaces. This research aims to design a sandblasting tool using Capstone Design analysis. The process includes selecting the type of sandblasting tool, determining its specifications, and calculating the dimensions of the blasting chamber. Additionally, the study involves assembling the sandblasting chamber, installing the required sandblasting components, as well as testing the functionality of the completed sandblasting system. Based on the functional testing results of the designed sandblasting tool, it can be concluded that the sandblasting tool functioned well and can be used by future researchers. From the roughness test results, it was found that the surface roughness after sandblasting is significantly higher compared to the initial condition.
