Decision Making to Choose Communication Network System for Teleremote Dozer Operation Using Analytic Hierarchy Process

One type of heavy equipment is a mining material pushing tool called a dozer. Dozers generally work in areas near cliffs that are prone to landslides, where these areas can be classified as dangerous areas. New technology is needed to increase the safety of dozer operators from the threat of danger when operating a dozer. Teleremote dozers are one method that can reduce the risk of accidents that can happen to dozer operators. Instead of operating the dozer from inside the cabin, the operator operates the dozer via a remote control device.

There is an important aspect in operating a teleremote dozer, namely the need for a signal that will transmit data and commands from the remote control to the dozer unit operating in the field. Good and uninterrupted signal quality is the main key to good teleremote dozer operations with minimal risk.

The wireless signal network system currently used by companies will enter its obsolete period. However, the old system was tough and not easily damaged. There are strategic options for supporting the signal network for teleremote dozer operations: maintaining the old network system, replacing it with a new one, or using the old and new systems in a hybrid manner. Because there will only be one strategy chosen, a decision must be made. The SWOT AHP method is used for decision making regarding the strategy to be taken. The results of the AHP SWOT will produce a strategy, which will become a benchmark for making subsequent alternatives. Determining alternative types of network systems to support teleremote dozer operations will use the AHP method.

Determining The Contract Service Strategy at Coal Terminal Maintenance to Address Contractor’s Inability to Maintain Availability of Fixed Plants in Supporting Shipments Activities at PTKPC a Case Study PTKPC, East Kutai, East Kalimantan, Indonesia

PTKPC, a coal producer, was facing challenges due to a permit transition in December 2021 from Coal Mining Contract of Work (PKP2B) to Special Mining Business License (IUPK). This change increases operational costs with added royalty rates, value-added tax, and profit-sharing obligations. To address this issue, the company decided to streamline contractors in each department in all business units, consolidating various tasks under one umbrella contract. The goal is to provide a big volume of work, potentially lowering rates and reducing PTKPC’s operational costs. However, relying on a single contractor for crucial operations, as seen in the Coal Terminal Maintenance Department (CTMD), introduces risks. The sole contract winner, PTPB, struggles to meet obligations since the contract’s initiation on December 1, 2021. The average contract fulfillment since commencement date is 86% of 100% desired target, disrupting fixed plant Coal Terminal maintenance activities. Physical availability is 93%, below the 94% target, increasing CTMD’s maintenance costs by $0.059 per ton. This research seeks to identify the root causes of PTPB’s inability to fulfill contractual duties and explore alternative solutions. and then from all the existing alternatives, what is the best alternative in responding to this condition. Utilizing primary and secondary data from PTPB’s monthly proforma invoices, contract scope, and CTMD’s monthly reports, the research employs methodologies like problem tree analysis and stakeholder analysis to unravel business complexities and identify root cause of the problems. Qualitative data collection methods, including focused group discussions (FGD) and semi-structured interviews, will be used to determine alternatives. These alternatives will be assessed using the Value-Focused Thinking (VFT) methodology. The Analytic Hierarchy Process (AHP) methodology, assisted by the AHP Super Decision application, will determine the best alternative: the “Implementation of Warnings and Penalties to PTPB”. Implementing this alternative demonstrates PTKPC’s commitment to stakeholders, ensuring contractor accountability without disrupting fixed plant maintenance. Penalty funds will support CTMD’s financial viability, funding additional resources for tasks beyond PTPB’s capacity. This strategy may be applied to other contracts within PTKPC.

Cost Optimization and Risk Management Program for the Fuel Supply Network in an Oil & Gas Swamp Operation

Marine activity is a critical part of an oil & gas company that operates in the swamp area. The company utilizes rigs, barges, and boats to achieve maximum production. Fuel supply for marine fleets is highly essential to ensure smooth operation. Since fuel cost becomes one of the biggest components of operating expenses (OPEX), the stakeholders highly encourage cost optimization programs to ensure business profitability. However, any optimization program shall have a robust risk management program to avoid disturbance in the operation and potential financial losses.

The research aims to select the best fuel supply network in the swamp operation area of an oil & gas company using four criteria (operational expenses, service reliability, value creation, and health safety & environment) based on the literature review and subject matter experts’ analysis. The study will analyze several alternatives using the Analytical Hierarchy Process (AHP) as a decision-making tool and Failure Mode Effect Analysis (FMEA) as the risk management method. The result shows that the hybrid network has the highest rating in AHP with a 33.7% rating and the lowest total risk priority number with 212 points.

Analytical Hierarchy Process as a Priority Strategy for Handling Bad Debts in Cooperatives

The Kediri City Government and the Regional Development Planning Agency are committed to accelerating the economic recovery of the Kediri city community after the impact of the Covid-19 pandemic, by focusing on MSME capital, the program named Kredit Usaha Melayani Warga or abbreviated as KOPERASI provides very low interest loans of 2% per year for business people in Kediri city. In the utilization of this credit, it turns out that there are still bottlenecks in installments, which if allowed to continue, will have an impact on financial losses and also not achieve the goal of community economic recovery. So that the government needs an in-depth study as a real form of handling bad credit and also the concept of effective and efficient KOPERASI program governance. This research uses a quantitative descriptive approach, by applying the Analytical Hierarchy Process (AHP) method. Starting from making questionnaires and determining respondents. The respondents selected were 7 experts, namely, officials at the Kediri City Cooperative & UMTK Office, lecturers at the Faculty of Economics, Universitas Nusantara PGRI Kediri, and MSME beneficiaries of the KOPERASI program. Then the answers are assessed and compared to produce a scale as a determination of the most effective method of overcoming bad credit.

Project Selection of Indonesian Local Oil and Gas Service Company Using Analytical Hierarchy Process (AHP)

PT Duta Wisesa Servisindo or PT. DWS is a local Indonesian company that offers services in the oil and gas sector. This company was founded in 2015 when world oil prices were falling and used this momentum to invest in assets, especially in cementing units used for drilling and workover work. At the beginning of the establishment of PT. DWS believes that they can become the main local Indonesian oil and gas services company in Indonesia, because many local competitors stopped their businesses during the 2015 crisis.

In 2023, world oil prices have improved, at the end of 2023 PT. DWS received 4 job offers from SOE and private sector to work on in early 2024, namely the Jambi Project, Lampung Project, Jambi Project and Cepu Project, but due to unit limitations, this company could only choose 3 job offers to work on. Because PT. DWS does not yet have a decision-making process. In this research, the Analytical Hierarchy Process or AHP is used to provide recommendations for 3 projects that are recommended to be taken by the company.

In this AHP assessment, the criteria used as assessment parameters are marketing and sales, customers, financial feasibility, administration and project specifications, each of these criteria has several sub-criteria with a total of 13 sub-criteria. Based on the assessment, the criterion with the highest weight is financial feasibility (51.4%) and the sub-criterion with the highest weight is ability to pay (22.9%). After the assessment was carried out, based on the ranking, the 3 projects that were recommended to be taken were the Jambi project (33.4%), Cepu Project (30.7%) and Lampung Project (19%). Based on the assessment results, it can be seen that service users from the BUMN sector dominate compared to the private sector because they have the ability to pay and have high profitability compared to private companies, even though private companies are superior in terms of payment, administration and equipment requirements.

Proposed Improvement of Contractor Selection for Maintenance of Reactor Effluent Air Cooler Using Value-Focused Thinking and Analytic Hierarchy Process at PT KPI RU V Balikpapan

PT KPI RU V Balikpapan performs turnaround to ensure equipment reliability for domestic oil and natural gas production.
