Abstract

The high consumption of natural aggregates in concrete production has led to increased exploitation of natural resources, causing environmental degradation. At the same time, the natural stone industry, particularly Onyx stone processing, generates a significant amount of solid waste that has not been optimally utilized. This study aims to evaluate the effect of using Onyx stone waste as a partial substitution for coarse aggregate on the compressive strength of concrete cylinders and the aesthetic quality of concrete surfaces. A quantitative approach with a pure experimental method was employed. Concrete cylinder specimens with a diameter of 150 mm and a height of 300 mm were prepared with Onyx waste substitution levels of 0%, 10%, 20%, and 30%, with five specimens for each variation. Compressive strength testing was conducted at 28 days in accordance with SNI 1974:2011, while aesthetic aspects were evaluated through visual observation of the concrete surface. The results indicate that Onyx waste substitution of up to 10% does not cause a significant reduction in compressive strength compared to control concrete, with an average value of 28.16 MPa. However, substitutions of 20% and 30% result in statistically significant strength reductions. In terms of aesthetics, higher Onyx content enhances surface color variation and texture. Therefore, the use of Onyx stone waste is recommended as an alternative coarse aggregate up to a maximum level of 10% to achieve environmentally friendly concrete with adequate mechanical performance and improved aesthetic value.

Abstract

Abstrak Kerusakan jalan merupakan permasalahan umum yang terjadi pada berbagai kelas jalan di Indonesia dan memberikan dampak signifikan terhadap keselamatan, kenyamanan berkendara, efisiensi perjalanan, serta kualitas lingkungan sekitar. Penelitian ini bertujuan untuk menganalisis jenis-jenis kerusakan jalan, mengidentifikasi penyebab dominan, serta memahami dampaknya terhadap pengguna jalan dan lingkungan. Metode penelitian menggunakan pendekatan deskriptif kualitatif yang didukung observasi lapangan, dokumentasi, dan kajian literatur. Hasil penelitian menunjukkan bahwa jenis kerusakan yang sering ditemukan meliputi lubang (potholes), retak (cracks), amblas (rutting), kerusakan tepi (edge ​​break), dan permukaan terkelupas (ravelling). Kerusakan tersebut meningkatkan biaya operasi kendaraan, risiko kecelakaan, keterlambatan lalu lintas, serta emisi karbon akibat perlambatan dan pengereman berulang. Dari aspek lingkungan, kerusakan jalan turut berkontribusi terhadap polusi debu, gangguan, penampungan udara, dan gangguan sistem drainase. Penelitian menyimpulkan bahwa pemeliharaan rutin, perencanaan drainase yang baik, serta penggunaan material perkerasan yang lebih tahan lama mampu mengurangi tingkat kerusakan. Penelitian lanjutan dapat menghasilkan pemodelan kuantitatif untuk prediksi tingkat kerusakan serta evaluasi strategi pemeliharaan berbasis biaya.
