Fuel is an essential commodity in both the economy and society. Indonesian fuel demand continues to increase annually, whereas fuel production has decreased. Gasoline accounts for more than 50% of fuel consumption for transportation. A reliable gasoline product demand forecast is required to plan the gasoline supply. The objective of this study is to forecast the demand for total gasoline and its three components, which are gasoline 88, gasoline 90, and gasoline 92. This study compared the Holt-Winters additive model and autoregressive integrated moving average for the time-series data for the 2017-2019 period. Because the Holt-Winters additive model generates more accurate results, it was applied to predict the total demand for gasoline during 2020-2022. The results of the combination of the Holt-Winters model and a neural network to forecast gasoline 92 demand had lower errors than the individual Holt-Winters method. The forecast results show that total gasoline demand is forecasted to increase, but the components indicate a different trend. Gasoline 92 and gasoline 88 decreased, but gasoline 90 increased.

This study develops a framework of governance mechanisms and human resource capabilities for the effective flow of information within the organization. This research is an exploratory research based on secondary data using a literature study methodology. The results of the synthesis show that the governance mechanism determines the success of information flow. The results also indicate the need for human resource capabilities to support governance and information sharing mechanisms. There are two types of governance mechanisms: formal and informal governance. Formal governance includes contracts, business processes, performance appraisal and information systems, and cross-functional teams. Meanwhile, informal governance includes trust, commitment, power and social interaction. Human resources with systems thinking, mastery of technology, and interpersonal skills are very valuable for sharing information. This study helps to understand the factors that affect the effectiveness of information flow.

<span lang="EN-US">The supply chain is a series of operations consisting of interconnected units both within and outside the company such as suppliers, producers, and distributors, each of which holds information at a different level. These parties need to be coordinated using information sharing as a coordination mechanism. Information sharing enables them to make the right and quick decisions that can improve the performance of the supply chain. Information sharing has received a lot of attention from researchers who analyze it from different perspectives. However,  no research shows the relationship between factors that drive information sharing to succeed. This study produces a model of power, trust, and information sharing.</span>
