ABSTRACT: The high rate of consumption of fossil fuels in Indonesia encourages PT Borneo Energi Indonesia to continue to increase oil and gas production. This is a challenge for PT Borneo Energi Indonesia which has mature well assets that require huge maintenance costs, and this is a contributor to the company’s increasing costs during the 2020-2022. This has a significant impact on profits and the business continuity business in the future. Therefore, a cost optimization program needs to be carried out to assist companies in maintaining profit.

This study uses qualitative methods, data obtained through in-depth interviews and Focus Group Discussion (FGD). The questions posed in the one-on-one interviews and FGDs were aimed at observing how far the respondents knew the condition of existing costs in the company, their impact on company profits, and the impact on economic, social, and environmental aspects as an indicator of corporate sustainability. The results show that the role of Synergy & Borderless Operation and Digitalization are pillars that need to be prioritized in responding to future challenges, especially in the industry 4.0 era, as well as the dynamics of organizational change that occurred after the implementation of sub holding and regionalization to build business continuity.
