Abstract

In spurring increased regional agricultural production, improving the irrigation network is the lifeblood of regional economic growth. It is hoped that handling the irrigation network will be able to stimulate agricultural production and restore the welfare of farmers in order to improve the economy while protecting the environment. As a first step in improving, maintaining and rehabilitating irrigation networks, careful planning is needed to obtain work data according to implementation standards and specifications. Posso Irrigation Area is one of the irrigation areas under the authority of the North Gorontalo Regency Government which is located in Kwandang District. Condition of irrigation network D.I. Posso is currently experiencing a decline in function and capacity due to sediment buildup and channel conditions that require maintenance. With a channel length of 1,381 meters that requires maintenance and cleaning of sediment and requires a physical budget of IDR 186,000,000.00 (One Hundred and Eighty Six Million Rupiah), which is expected to restore the function of the channel in the irrigation network Posso.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penambahan plastik daur ulang jenis High-Density Polyethylene (HDPE) terhadap karakteristik campuran aspal AC-WC (Asphalt Concrete – Wearing Course). Metode yang digunakan adalah eksperimen laboratorium dengan pengujian Marshall untuk mengevaluasi parameter stabilitas, flow, Void in Mix (VIM), Void in Mineral Aggregate (VMA), dan Void Filled with Bitumen (VFB). Variasi kadar HDPE yang digunakan adalah 0%, 2%, 4%, 6%, dan 8% terhadap berat aspal. Hasil penelitian menunjukkan bahwa penambahan HDPE meningkatkan nilai stabilitas hingga mencapai nilai optimum pada kadar 6%, kemudian mengalami penurunan pada kadar 8%. Nilai flow cenderung menurun seiring peningkatan kadar HDPE, yang menunjukkan peningkatan kekakuan campuran. Parameter volumetrik menunjukkan bahwa nilai VIM dan VMA menurun, sedangkan VFB meningkat, yang mengindikasikan peningkatan kepadatan dan durabilitas campuran. Secara keseluruhan, kadar optimum HDPE berada pada kisaran 4%–6%, yang memberikan keseimbangan antara kekuatan dan fleksibilitas. Secara teoritis, HDPE meningkatkan kinerja campuran melalui modifikasi sifat reologi, pembentukan struktur mikro penguat, serta peningkatan interaksi adhesi dan kohesi. Selain itu, penggunaan HDPE juga mendukung prinsip pembangunan berkelanjutan melalui pemanfaatan limbah plastik dan berpotensi menurunkan biaya siklus hidup perkerasan jalan.
