Abstract

Negara Indonesia adalah negara kepulauan yang memiliki berbagai macam sumber daya yang melimpah dari alam atau buatan manusia. Salah satunya pasir pantai, indonesia memiliki pasir pantai yang sangat melimpah yang masih belum dapat dimanfaatkan dengan maksimal. Selain itu, kini manusia semakin jarang peduli dengan kebersihan. Dapat mudah ditemukan sampah plastik yang berserakan, data kebersihan selalu ditemukan sampah berjenis plastik karena sifatnya sekali pakai dan memiliki fisik yang tipis dan elastis. Permasalahan ini menjadikan pasir pantai dan plastik menjadi inovasi material dalam campuran aspal untuk mencari mutu yang lebih baik. Dalam penelitian menggunakan pasir pantai sebagai agregat halus, penggunaan pasir pantai ialah 100% tertahan saringan No. 16 sampai pan dan subtitusi plastik jenis LDPE (Low Density Poly Ethylene) secara basah dalam aspal penetrasi 60/70. Hasil pengujian Marshall, tiga parameter mengalami penurunan pada campuran aspal modifikasi dibandingkan campuran aspal konvensional. Nilai MQ turun 0,8% pada variasi agregat halus pasir pantai Probolinggo dan Malang. Nilai VFA turun 0,96% pada variasi agregat halus pasir pantai malang dan 0,89% pada variasi agregat halus pasir pantai Probolinggo. Nilai VMA turun 1% pada variasi agregat halus pasir pantai Probolinggo. Pada nilai Stabilitas naik 1 % pada variasi agregat halus pasir pantai Malang dan Probolinggo. Nilai Flow naik 1,2 % pada variasi agregat halus pasir pantai Malang dan 1,1% pada variasi agregat halus pasir pantai Probolinggo. Nilai VIM naik 1,1 % pada campuran aspal agregat halus pasir pantai Malang dan 1% pada campuran aspal agregat halus pasir pantai Probolinggo. Nilai VMA naik 1,03% pada campuran aspal agregat halus pasir pantai Malang. nilai Densitas mengalami kenaikan 1% pada campuran aspal agregat halus pasir pantai Probolinggo.

The State of Indonesia is an archipelagic country that has various kinds of abundant natural or man-made resources. One of them is beach sand, Indonesia has very abundant beach sand which still cannot be utilized optimally. In addition, now humans are less concerned with cleanliness. You can easily find scattered plastic waste, cleanliness data always finds plastic type waste because it is disposable and has a thin and elastic physique. This problem makes beach sand and plastic a material innovation in asphalt mixtures to seek better quality. In a study using beach sand as fine aggregate, the use of beach sand was 100% retained by filter No. 16 to wet pan and substitution of LDPE (Low Density Poly Ethylene) plastic in 60/70 penetration bitumen. Marshall test results, three parameters decreased in the modified asphalt mixture compared to conventional asphalt mixtures. The MQ value decreased by 0.8% for the fine aggregate variation of Probolinggo and Malang beach sand. The VFA value decreased by 0.96% for the fine aggregate variation of Malang beach sand and 0.89% for the fine aggregate variation for Probolinggo beach sand. The VMA value decreased by 1% for the fine aggregate variation of Probolinggo beach sand. The Stability value increased by 1% in the fine aggregate variation of Malang and Probolinggo beach sand. The Flow value increased 1.2% for the fine aggregate variation of Malang beach sand and 1.1% for the fine aggregate variation for Probolinggo beach sand. The VIM value increased by 1.1% in the fine aggregate asphalt mixture of Malang beach sand and 1% in the fine aggregate asphalt mixture of Probolinggo beach sand. The VMA value increased by 1.03% in the Malang beach sand fine aggregate asphalt mixture. Density values increased by 1% in the fine aggregate asphalt mixture of Probolinggo beach sand.
