KAJIAN PEMBANGUNAN FLYOVER DI JALUR HAULING SIMPANG HUMMER KM 73 AREA SOUTH TUTUPAN TERHADAP PRODUKSI BATUBARA PADA ALAT ANGKUT TRAILLER DI PT ADARO INDONESIA,TABALONG, KALIMANTAN SELATAN
Abstract. Mining is the process of extracting natural resources, with coal being one of the primary export commodities. In mining operations, infrastructure such as hauling roads is crucial to support the movement of heavy equipment, especially in areas with extreme conditions. One critical point is the Hummer Intersection, which is traversed by haul trucks such as HDDTs and Trailers. This intersection often experiences congestion, leading to increased standby time and cycle time, ultimately reducing productivity. On March 3, 2025, data recorded the use of New Volvo FH16 550HP-Double SST 74 Quadaxle trucks operating 24 hours a day in two shifts. The total travel time was 613.90 minutes per day, consisting of 231.20 minutes when loaded and 209.10 minutes when returning empty. Standby time at the Hummer Intersection reached 169.30 minutes per day, with a total of 200 trips. The actual production achieved was 767,060.1 tons per month. The main issue lies in the high standby time at the intersection. The proposed solution is the construction of a flyover to separate traffic flows, eliminate waiting time, and improve operational efficiency. After the flyover was built, travel time decreased to 342.65 minutes, helping to streamline the coal hauling process. Abstrak. Pertambangan adalah proses pengambilan sumber daya alam, salah satunya batubara sebagai komoditas ekspor utama. Dalam operasional tambang, infrastruktur seperti hauling road sangat penting untuk mendukung pergerakan alat berat, terutama di area dengan kondisi ekstrem. Salah satu titik krusial adalah Simpang Hummer yang dilalui alat angkut seperti HDDT dan Trailer. Titik ini sering mengalami kemacetan, menyebabkan peningkatan waktu tunggu (standby) dan cycle time, yang berdampak pada penurunan produktivitas. Data tanggal 3 Maret 2025 mencatat penggunaan alat angkut New Volvo FH16 550HP-Double SST 74 Quadaxle, dengan operasional 24 jam dalam dua shift. Travel time tercatat 613,90 menit per hari, terdiri dari 231,20 menit saat berangkat muatan dan 209,10 menit saat kembali kosong. Waktu standby di Simpang Hummer mencapai 169,30 menit per hari dengan total ritase 200. Produksi aktual tercatat sebesar 767.060,1 ton/bulan. Permasalahan utama adalah tingginya waktu tunggu di simpang tersebut. Solusi yang diusulkan adalah pembangunan flyover untuk memisahkan arus lalu lintas, menghilangkan waktu tunggu, dan meningkatkan kelancaran operasional. Setelah pembangunan flyover, travel time menurun menjadi 342,65 menit, yang membantu memperlancar proses pengangkutan batubara.
