Coal production produced by PT. Prima Dito Nusantara by dumptruck is currently 9.977,48 ton/bulan, looking at the condition of the existing equipment, it is planned to produce daily from the dumptruck to be further improved so that the production that can be achieved by the dumpt truck can reach 15,000 tons / month. Therefore, the problem to be examined is "is the condition of the haul road being used at this time ideal to achieve the coal production target of PT .Prima Dito Nusantara". With the evaluation of haul roads are expected to help the problems that exist in the company so that the productivity of the means of transportation to increase and production to be achieved. The research method conducted in the field is by measuring along the haul road from the mining front to the rom stocpile by calculating the width of the haul road, the distance and the slope and then comparing the actual condition in the field with the result of calculation based on the theory. The results showed that the width of the minimum haul road for straight road conditions must be made that is 11 m and 15 m for the bend.The slope at the bend (superelevation) with the theoretical bend width of 15 m must be made 30 cm so that the transport can pass the bend with maximum speed. Based on the theoretical width of the cross slope to be made is 22 cm to the side of the road so that the road body is not inundated with water, while the slope of the haul road is 15%. The results of the research analysis will then be made a recommendation as a solution of the problems that occur.

Abstract. Pit Sari coal production target PT. Adimitra Baratama Nusantara in April 2018 amounted to 200,850.0 tons / month, but the amount of coal mined in pit sari in April was only 194.645,27 tons. The combination of transport and loading equipment used is 1 unit Caterpillar 349D excavator with 6 units of Dump Truck Iveco 380 Trakker. After measuring the width of the straight road and the bend, it was found that the condition of the width of the road was not yet in accordance with the wide standard that can be passed by the conveyance. One solution to increase production is to improve road geometry conditions such as increasing the width of the road, decreasing the slope of the road, to pay attention to cross slope and superelevation. Based on the calculation of road geometry evaluation, the width of the straight road and the bend that is passed by OHT Caterpillar 777D is 21,58 meters and 24,08 meters. While for the standard road width passed by Iveco Dump Truck itself is 13,53 meters and 16,08 meters. Road grade > 9% must be reduced to 9%. The cross slope number that must be made is 43,16 cm for the road that is passed by OHT, 27,06 cm for the road that is passed by the Dump Truck Iveco 380 Trakker. The super elevation that must be made is 74 cm. Production after repairs to the haul road geometry reached 217.167,57 tonsKeywords: Dump Truck, Iveco 380 Trakker, Road Geometry, Production, Cycle Time.

Abstract. Flyrock is the fragmentation of rocks that are thrown due to result of blasting. Fragmentation of rocks thrown over a safe radius can cause damage to mechanical devices, injuries, and even death to humans. This is what causes the effects of flyrock to be one of the main concerns in every blasting activity. This study aims to analyze the better of geometry in order to reduce the distance of flyrock. The study was conducted on 11 blasting blocks, by comparing the distance of flyrock before and after the geometric changes of the blasting, including seven blasting without simulation and four blasting with the simulation. Observation of the distance of flyrock in detail using DJI Phantom 4 drones and plotting coordinates with GPS (Global Positioning System). Theoretically the distance of rock throws according to the empirical method with the theories of Richard and Moore (2005) is 65 m, and Lundborg (1981) 107.25 m. Whereas according to the method of dimensional analysis with the theory of Ebrahim Ghasemi (2012) it is 110.53 m. Of the seven blasting activities obtained the average distance of rock throws (flyrock) is 143 m with the farthest distance of 160 m. Thus Ebrahim Ghasemi's theory is more representative in predicting the distance of rock throws because it has a smaller difference (22%). Simulation of blasting activities is carried out by changing geometry in stemming depth, because statistically stemming has a very strong relationship to the distance of flyrock (R2 = 0.84), where stemming can control energy in the hole so it is not released upwards in giving rocks to the side. Besides that the increase in stemming causes hole depth to also increase. From the four blasting simulation activities carried out, the average flyrock distance was 53.95 m with the furthest distance 63.2 m. This means that with the simulation the distance of flyrock can be minimized by 89.05 m or about 62.27%.Keywords: Blastability Geometry, Flyrock
