Abstract

The Srandakan-Poncosari-Pandansimo road section, Srandakan District, Bantul Regency, Yogyakarta Special Region Province is a road that connects Bantul City with tourism sites. Based on its function, the Srandakan-Poncosari-Pandansimo road section is included in the Provincial road category. In order for the road to be used properly, the road must be made and designed and maintained in accordance with the requirements set by the government. Road pavement is a layer of pavement that lies between the subgrade and the wheels of the vehicle. There are three types of pavement, namely flexible, rigid and composite or combined pavement. Geographic Information System is a spatial information technology system that is commonly used today. In general, GIS works based on five components, namely hardware, software, data, people, and methods. The selection of data methods using GIS because of the ability of GIS programs that can answer the needs of efficient information systems and are able to process data with complex structures and geographic (spatial) based. GIS is able to store, analyze, present spatial data and atri but data (tables), able to answer spatial questions (how long, wide etc.) so as to provide more informative data than other computer-based information systems and can help make decisions quickly and accurately. In this study, the percentage of road damage is 3.110345%. The types of damage on the Srandakan-Poncosari-Pandansimo road section are longitudinal cracks, random cracks, alligator cracks, potholes, collapse or deformation and patches.

Abstract

Pemanfaatan slag baja sebagai pengganti agregat kasar pada beton merupakan inovasi yang dapat mengurangi limbah industri sekaligus mendorong pembangunan berkelanjutan. Penelitian ini bertujuan untuk mengkaji kelayakan slag baja sebagai pengganti agregat kasar alam melalui serangkaian uji laboratorium sesuai standar SNI dan ASTM, meliputi uji kuat tekan, berat jenis, abrasi, dan kadar air. Hasil penelitian menunjukkan bahwa kuat tekan beton dengan slag baja belum mencapai 85% dari kuat tekan yang direncanakan, sehingga diperlukan penelitian lebih lanjut mengenai komposisi campurannya. Namun, pemanfaatan slag baja dapat menekan biaya produksi karena merupakan limbah tanpa nilai jual. Selain itu, pemanfaatannya juga berpotensi mengurangi emisi karbon hingga 50 - 60% melalui pengurangan penambangan agregat alam. Inovasi ini sejalan dengan SDG 9 dan SDG 12 serta menawarkan solusi yang ramah lingkungan dan ekonomis bagi industri konstruksi. Dengan pengembangan lebih lanjut, beton berbasis steel slag dapat menjadi material alternatif yang berkelanjutan dalam mendukung infrastruktur masa depan.
