Abstract

Abstract:. Development is a process of making aperture (tunnel) is done by dismantling (excavation) both manually and mechanically. The results to be obtained that is in the form of opening holes according to Grasberg Block Cave (GBC Mine) production plan based on the purpose of the open pit function. Propose is done to support other fix facility in order to support the Production Plan in 2018. Completion of a hole openings (Tunnel) with the rule that is a continuous stage (cycle development) that there must be a good control system of development process. Control that is done design engineering and its application in the field. The fact is that in 2015 - 2016, the target gain is not in line with expectations and causes the meter (d Equivalent meter) of operational development at the extraction level in the GBC Underground mine to decrease by 50 - 55% or about 641 meter up to 1000 meter difference of the second plan of the year.Identification of the current problem is the process of progress of opening aperture that has not reached the target because one of the process in the cycle development of Mucking and Hauling not achieved the target because of some basic things. The minimal information and low support of the reporting system caused some strategic decisions to be delayed and caused simultaneous cycles to experience significant constraints. A centralized and fast-accessible Information System from either input or share data by all stakeholders responsible for operational project development tunnel is very supportive. Good motivation greatly affects the performance of each stakeholder working on the project, so that the appropriate approach according to Human needs can be done in order to increase productivity.Project Management with CPM method as well as Human Resource Management (Motivation application of Abraham Maslow) becomes an option in humanizing according to the Root problem obtained by the Current Reality Tree method. The hope is that the development process runs quickly, safely and safely and operational with little operational expense and minimal repetitiveKeywords: cycle development, production plan, underground mine

Abstract

An Indonesia manufacturing company producing Airbus wing parts experienced losses of more than $100,000 in 2017. The production of A 380 wing parts contributed to 73% of the total losses, and 37% came from parts production of A 350 and A 320. The study focused on the most significant contribution losses of A 380 wing parts that is Drive Rib 1.  This paper aims at examining the root cause of the loss in A 380-Program, solving the root cause by proposing the alternative solution, and improving the performance in A 380 Program. By conducting the interview and archival data, the data were analyzed employing Root Cause Analysis (RCA) to discover the root cause of problems. Low reliability of the production machine (DGAL Cincinnati Milacron) was identified as a root cause indicated by Overall Equipment Effectiveness (OEE) at 50.3% used since the 1980s. According to Total Productive Maintenance (TPM), this study proposes three alternative business solutions (autonomous maintenance, quality maintenance, and machine replacement). By considering the results of OEE and Analytical Hierarchy Process (AHP) with three criteria (cost, benefit, and implementation), the problem-solution proposes two approaches, namely conducting the autonomous maintenance with an improvement of OEE about 7% for the short term period and organizing the machine replacement with a significant OEE improvement about 17.1%.

Abstract

PT XYZ is a PT ABC (Persero) subsidiary under Sub-Holding Commercial & Trading, PT KLM. PT XYZ is responsible for operating COCO gas stations owned by PT ABC. As time goes by, PT ABC's competitors are increasingly developing their business and increasing their outlets, which will become a challenge for PT XYZ. As one of the efforts to deal with this competition, PT XYZ is constantly upgrading and improving the appearance of gas station facilities, ensuring that the facilities function correctly so that customers will feel comfortable and always fill their vehicles at COCO gas stations. This is also stated in the company's strategy and listed in the 5R program (Ringkas (Brief), Rapi (Neat), Resik (Clean), Rawat (Caring), Rajin (Diligent)). To accommodate the above strategy, PT XYZ also allocates a capital goods investment to implement repairs/renovations in the existing Fuel Station. In practice, the project’s physical performance gap caused PT XYZ to not achieve the Key Performance Indicator according to the target. The Technical function as the executor function in the implementation of the projects plays a vital role in implementing the project on time, which will undoubtedly affect the project’s performance in PT XYZ. The Key Performance Indicator also cascaded to Technical Function as the Construction Accuracy Performance point. The purpose of this study is to find the root causes of the obstacles faced by PT XYZ in project planning and find solutions to solve these problems so that the project can be completed on time and the KPI for Non-Business Development Capital Goods Investment is achieved. To look for problems, research was conducted at a gas station in the Jabodetabek area with specific criteria. Interview methods will be conducted with stakeholders who play a role in the gas station renovation project. The current reality tree method will analyze problem identification to get the root cause. Case studies and literature reviews will be conducted to find a theory to resolve the root cause. PMBOK, especially in the project schedule management and planning process group sections, and Operation Management theory, especially Lean Production, will be used to analyze the project's performance and find a solution. Several alternative solutions will be identified based on the root cause obtained. Then the best alternative solutions will be selected by using AHP (Analytical Hierarchy Process) with the criteria and rating of the results of interviews with stakeholders. An implementation plan for the best alternative solution will be designed and used as a recommendation for the company.
