Abstract

Abstract - The oil and gas industry in Indonesia is going through a difficult period due to the drastic decline in global oil prices since the year 2014. One way to stay competitive when the low selling price is to work more efficiently and reduce operating costs. Saka Indonesia Pangkah Limited is a subsidiary of PT. Saka Energi Indonesia and its parent company, PT. Perusahaan Gas Negara. The company is operating as upstream oil and gas contractor under PSC agreement with the government of Indonesia, represented by SKKMIGAS. The efficiency discussed in this report is the streamlining and improvement of the procurement process using Lean Six Sigma concepts and ultimately supported by better electronic system implementation. The business problem was first defined by mining data from the past year as well as obtaining customer inputs. From the existing data then further research was conducted to find the root of the problem. After determining the root of the problem, the analysis is continued to make improvements to the process applied at the time. Process improvement is done by applying Lean's basic principle of prioritizing value to end users, reducing waste, flowing processes, and user-driven demand systems rather than driven by process capacity. The analysis recommends the application of electronic procurement system (e-procurement) to control the implementation of procurement process so that there is minimal variation of process which can cause inefficiency.Keywords: oil and gas, procurement, lean six sigma, e-procurement

The instability of total products demand cause production planning changes every week. The first thing to do is identifing the product combination which will be produced. The product combination can be determined by using linear programming method. The aim of linear programming method is to determine the product combination which will be produced. Therefore, the company can optimize the production capacity of the company to get maximum revenue. If the company is not able to fulfil all demand, the company can do outsourcing production. Outsourcing production is the act of moving some of a firm’s internal activities to outside provider. But the weakness of outsourcing production is a lack of communication between the company and the outsourced provider may occur production delay and the quality of the product is not necessarily the same as the company's quality standards. Therefore, the company must maximize the use of production capacity first, then it could use outsource production.Keywords: Linear Programming, Outsourcing Production, Production Planning, Production Capacity

Abstract - PT Karunia Food is a company which engages in in-flight catering to support catering and logistic supplies for a national airline. For the logistic supplies, PT Karunia Food must prepare various kinds of inventories, such as monouse, multiuse, dry goods, and beverages. The logistics that have been arranged to trolleys or containers will be transferred to the assembly line and will be uplifted to the aircraft. The business process will be continued after the aircraft landing because the multiuse inventory will be offloaded from the aircraft and transferred back to each setup area. The absence of recording the items that offload from the aircraft caused a lot of loss and breakage items which generate an increase in inventory cost. To reduce it, PT Karunia Food will implement barcoding system to control the inventory items that the company have. With this system, the items that will be uplifted and offload after aircraft landed could be counted, so the items that already consumed can be calculated properly for the procurement planning. For the implementation of barcoding system, PT Karunia Food implements first on beverage and dry goods setup area. In this area, there are six setup processes of items needed for the aircraft, which are beverages, dry goods, mineral water, amenities, paper cups, and miscellaneous. But, for the implementation, there is a problem with the insufficiency of the area to do the barcoding process, so the barcoding system cannot be implemented. The research methodology used in this research is using qualitative method through the author’s observation and interview to find the root cause of does not have space to implement barcoding system. The interviewee are the head, administration officer, and staff that involves in the setup area. After interview, the author analyzes using the fishbone diagram and found that there are four root causes that make the company does not have enough space to implement barcoding system in the beverage and dry goods setup area, which are unclear flow process, does not have SOP (Standard Operating Procedure), unclear distribution of task, and unclear layout. The proposed solutions are making the new flow processes, making SOP, making clear job description, and making a new layout. Flow process analysis is being used to make the new flow processes. The first solution that the company has to applied is making the new flow processes first to make a process which have a proper flow which will be used for next solution, which is making a new layout. After those two solutions are done, the next solution is making SOP for each process and making a clear job description for the manpower. Keywords: Setup Area, Flow Process, Re-Layout, Fishbone Diagram

Abstract

Upstream oil and gas industry is vital to Indonesian economy, more than 30% of states revenues generated from the sale of crude oil and natural gas. Government of Indonesia (GOI) is the holder of mining rights and in practice can delegate the mining rights to both local and foreign contractors to be managed in the form of production sharing. This model known as Production Sharing Contract (PSC). One of the feature of PSC contract is the reimbursement on costs incurred by the contractors in their oil and gas operations. Since 2000, oil production continues to decline, while the number of cost recovery for producing oil and gas continue to climb. The higher the cost recovery, the lower GOI share will be. Therefore, controlling the number of cost recovery needs to be done comprehensively so that the savings can be distributed to the welfare of Indonesian people. So far, BPMIGAS has made many efforts, such as joint-rig procurement, reduction of the number of expatriates, reduction of employee benefits, and many others. But there is one function that often overlooked, which lies in logistics function. This study attempts to identify the causes of surplus and dead stock material arise from logistics function in contractors, and to find the most appropriate solutions to reduce excessive buildup of materials in the future. Studies conducted using surplus and dead stock balance as of December 2011 to describe the actual condition. The combination of primary data, (field observation and interviews to respondents from the contractor and BPMIGAS) and secondary data (journals, books, papers, annual reports, monthly report) was performed to obtain comprehensive analysis. Based on data collection, there are two main causes of surplus and dead stock which are PSC contracts provision that allow non-capital inventory to be charged at the time the materials arrive in Indonesia, the other main cause is the lack of integrated system in material management combined with no uniform material codification among the contractors, thereby reducing the effectiveness of material transfer as a mean of optimizing the movement of assets. Subsequently, several alternative solutions are examined to obtain the optimal solution for controlling the rate of surplus and dead stock in the future. These include: consignment/vendor managed inventory, parts pooling, application of bar code and Radio Frequency Identification (RFID), to outsourced the logistics function, implementation of OEM parts, etc. Of the many alternatives that were examined, change the PSC term at the contract-renewal proposal  by the contractor and, and develop an integrated material management application which include codification can be implemented as the most effective way to mitigate the build up of excess materials in the future. In the end, savings from cost recovery will be greater because procurement of new material can be reduced. Keywords: inventory management, cost recovery, the oil and gas industry
