Abstract

Background: This research aims to: (1) develop a construction occupational health safety teaching module for students of the Department of Civil Engineering and Planning Education, Universitas Negeri Yogyakarta. (2 Assessing the feasibility of the learning media through assessments from material experts and media experts from the Department of Civil Engineering and Planning Education, Universitas Negeri Yogyakarta. Methods: The research method employed is Research and Development, utilizing a 4D (Four-D) development model. This model comprises four stages of development: Define, which represents the definition stage; Design, referring to the planning stage; Development, denoting the development stage; and Disseminate, which leads to the dissemination stage. Data collection uses questionnaires, and the analysis method applied is descriptive techniques. Results: The results of the development of the K3 Construction module are (1) The development process follows 4 stages, namely define, design, develop, and disseminate. In the definition stage, it was found that there was a problem that learning media were not available for the construction occupational health safety teaching module for students of the Department of Civil Engineering and Planning Education UNY. At the design stage, the design of the module script is done with Microsoft Word with A4 paper size (21 cm x 29.7 cm). The development stage includes validation by material experts and media experts. (2) The results of validation from material experts resulted in a score of 90.66%, categorized as "very feasible", while validation from media experts received a percentage of 90.21%, also categorized as "very feasible". Conclusion: Media for the K3 Construction module that is suitable for use in the K3 Construction course, Department of Civil Engineering and Planning Education, Universitas Negeri Yogyakarta.

Abstract

Flexible pavement failures in Indonesia are primarily attributed to weak subgrade conditions, necessitating soil reinforcement measures. This study aimed to enhance soil-bearing capacity through soil reinforcement experiments utilizing a mixture of sand columns, rice husk ash, and cement. A prototype was constructed, including a 1×1×1 m steel box, an IWF steel frame, a dial gauge, a steel plate, and a proving ring, to apply a load to soil arranged within the iron box using a 3-ton hydraulic jack. The study focused on a clay soil type (following the AASHTO method) and conducted soil reinforcement in four scenarios. The result shows that in all scenarios involving a sand column, Scenario 1: 3% sand, 3% rice husk ash, and 6% cement obtained a qult is 0.23 kg/cm2 and BCR 114.94%; Scenario 2: 3% sand, 6% rice husk ash, and 3% cement obtained a qult is 0.12 kg/cm2 and BCR 11.49%; Scenario 3: 6% sand, 3% rice husk ash, and 3% cement obtained a qult is 0.14 kg/cm2 and BCR 26.44%; Scenario 4: 6% sand, 6% rice husk ash, and 0% cement obtained a qult is 0.24 kg/cm2 and a BCR of 116.09%. Notably, scenario 4, featuring a column composition of 6% sand, 6% rice husk ash, and 0% cement, achieved a significant increase in bearing capacity (qult) with a value of 0.24 kg/cm2 and a high Bearing Capacity Ratio (BCR) of 116.09%. Scenario 1 was the most effective in reducing moisture content by 4% relative to the original soil moisture content, with a mixture comprising 3% sand column, 3% rice husk ash, and 6% cement. The findings suggest that applying soil columns can enhance the performance of flexible pavements.
