Pengaruh Geometri Jalan terhadap Produktivitas Pengupasan Overburden PT PSA, Kalimantan Timur

Abstract. This mining road geometry study research refers to the Minister of Energy and Mineral Resources Decree No. 1827/K/30/MEM/2018 and the American Association of State Highway and Transportation Officials. The surrounding environment consists of oil palm plantation areas and forests. Access to the location is quite difficult because the roads entering the mining area are not paved, especially when it rains. Based on the problems found at PT Pancaran Surya Abadi in the B1 Block A1-1 east pit, namely there are road conditions that do not meet regulatory standards, so that the production target for the July-August period is not achieved, namely 280,255 BCM/month from the pit location stripping overburden to disposal. To increase overburden mining production, the development of digging, loading, and hauling equipment is required. The production observation area was conducted at the working front in Pit A1. Observation results under actual conditions were calculated and compared with theoretical calculation results. In the observation area, the width of the straight road ranged from 11.13 meters to 23.74 meters with a comparison of theoretical results for roads using 2 lanes of 12.60 meters, the width of the bend road ranged from 16.36 meters to 24.39 meters with a comparison of the theoretical results of the minimum road width at the bend of 14.48 meters, and the slope of the road ranged from -0.2% to 23.13% with a comparison based on the theoretical standard slope of 12%. The actual calculation results show results that do not meet regulatory standards. Another cause is that with rainy conditions the road is damaged, so that the transport equipment's circulation time is getting longer, which will affect production. Therefore, roads that do not meet the standards require road geometry improvements. Abstrak.

Berdasarkan masalah yang terdapat pada PT Pancaran Surya Abadi pada pit B1 Block A1-1 timur yaitu terdapat kondisi jalan tidak sesuai standar regulasi, sehingga tidak tercapainya target produksi periode bulan Juli-Agustus yaitu 280,255 BCM/Bulan dari lokasi pit pengupasan overburden ke disposal. Untuk meningkatkan produksi penambangan overburden, pengembangan alat gali, muat, dan alat angkut diperlukan. Area pengamatan produksi dilakukan di front kerja di Pit A1. Hasil pengamatan dalam kondisi aktual dihitung dan dibandingkan dengan hasil perhitungan secara teori. Pada area pengamatan, lebar jalan lurus berkisar antara 11,13 meter hingga 23,74 meter dengan perbandingan hasil teoritis untuk jalan yang menggunakan 2 lajur yaitu 12,60 meter, lebar jalan tikungan berkisar antara 16,36 meter hingga 24,39 meter dengan perbandingan hasil teoritis lebar jalan minimum pada tikungan 14,48 meter, dan kemiringan jalan berkisar antara -0,2% hingga 23,13% dengan perbandingan berdasarkan teoritis kemiringan standar yaitu 12%. Hasil perhitungan aktual menunjukan hasil yang kurang memenuhi standar regulasi, penyebab lainnya dengan kondisi hujan jalan mengalami kerusakan, sehingga waktu edar alat angkut semakin lama yang nantinya akan berpengaruh terhadap produksi, oleh karena itu jalan yang belum memenuhi standar diperlukannya peribaikan geometri jalan.
