The measure of risk based on the probability of failure of structural and monetary consequences of failure, and accounts for the material damage from time to time. The purpose of this study was to determine the factors (events that enable the) risk on pile foundation work and determine the weight/risk priority ranking of pile foundation work execution. This study uses analysis Analytical Hierarchy Process (AHP) to obtain risk factors pile foundation dominant conveyor manufacturing building consisting of 21 risk factors (criteria). The risk assessment carried out by 5 (five) Expert. The results in getting the expert assessment of the risk factors pile foundation work of the most dominant is the criterion of cost control systems are a weak and weak time control system. Keywords: Analytical Hierarchy Process, Risk Management, Foundations Piles. ______________________________________________________________________________________________ 1. INTRODUCTION Industrial development in the business sector coal mining is a government effort to increase foreign exchange and if the terms of the pattern of community life is directly dependent on the increase in goods and services, the use of sources of energy, and natural resources. The use of natural resources massively without neglecting the environment can lead to various negative impacts felt in the short term and in the long term. Adequate equipment will increase the productivity of the company. Belt conveyor is one means of conveyance raw material most widely used in the industry. This tool also has a payload capacity large enough. Applications include conveyor belt transport means in the cement plant, coal, fertilizer plant and stone processing plant aggregates (stone split). This tool can transport bulk material or large chunks (eg, crack stone) up to moderate size (eg coal). PT X is one of the contractor mine in Indonesia which is currently developing the construction manufacturing conveyor. Conveyor construction using structures pile foundation. The foundation piles is one of the elements that serves to move the burden of building structures and building loads to the ground. Generally pile foundation been used or if the soil conditions are relatively stable and hard soil depth is affordable or not lies far below the soil surface. Jobs pile foundation worked land and river, this work certainly has a lot of risk on the workmanship both overland and river channels. In construction projects are characterized as a series of activities that take place in a limited time with a specific allocation of resources to produce products with criteria outlined in the contract document. Therefore at the time of construction, the developer will be burdened by a variety of uncertainties that are consequences risk. 2. ANALYTIC HIERARCHY PROCESS (AHP) This method is used to look at the dominant risk factor. Simply put, there are two main criteria that influence the rank of risk factors, namely the frequency or of opportunity for risk itself. One of the method of decision-making is using Analytic Hierarchy Process (AHP). Another advantage of using AHP is its ability to solve problems and multicriteria multiobjectives [1]. AHP is a decision-making process by using pairwise comparisons (pair wise comparisons) to explain the evaluation factors and weighting factors in multi-factor condition [2]. The method of analysis is essential to identify the variables that are relevant to the research results obtained in accordance with the purpose. As an input to this analysis is the data information on the results of the questionnaire respondents. AHP is a method used to solve complex problems and are not structured into groups, by organizing groups into hierarchies, then enter a numerical value instead of human perception of relative comparison. By the synthesis, it will be able to determine which elements should have the highest priority [3].
