/in /by

The research titled “Building a Learning and Leadership Ecosystem Using a Knowledge Management Perspective at PT Tri Satya Jaya” this research addresses significant challenges the company faces, particularly in performance decline and ineffective employee collaboration. The quantitative component involved administering a questionnaire called the Learning Organization Survey, modeled after Garvin et al. (2008), to assess the organization’s learning depth, while the qualitative aspect comprises interviews with directors to gain deeper insights into performance-related issues. The research used the tree analysis method to determine the root causes of the decline in company performance. Additionally, the study highlights that organizational culture plays a crucial role in influencing employee performance. A culture that does not prioritize knowledge sharing and continuous learning can lead to stagnation and inefficiencies, ultimately affecting the company’s competitiveness in the Engineering, Procurement, and Construction (EPC) sector.

A well-designed KM (knowledge management) Framework can facilitate the sharing and retention of knowledge. The study proposes strategies that leverage the SECI (socialization, externalization, combination and internalization) model to create a robust knowledge-sharing environment within the organization, by implementing the SECI model. The SECI model emphasizes the importance of social interactions in knowledge sharing, encouraging employees to collaborate and learn from one another. This research develops a detailed implementation timeline to ensure the effective integration of these KM strategies into PT Tri Satya Jaya’s operations. The timeline is structured in four key stages: the first is KM Preparation for Internal Company, the second is Designing Guidelines and Curriculum, the third is KM System Implementation, and the fourth is the KM System Evaluation.

The research concludes that investing in human capital and adopting effective leadership practices are essential for driving organizational success and competitiveness in the EPC sector. By establishing a robust learning and leadership ecosystem, PT Tri Satya Jaya can overcome its challenges and achieve sustainable growth. The recommendations that this research offers are as follows:  establishing a knowledge management team, investing in leadership development, creating structured mentoring programs, enhancing human capital investment, utilizing technology for knowledge management, and establishing performance tracking mechanisms.

The Laboratory Test of AOS and ABS Surfactant at 60oC for EOR Process

/in /by

Background: By 2021, global oil demand is expected to rise by 5.3 million barrels per day (bopd), while oil output is anticipated to decrease gradually. The fall in oil production was attributed to a decline in reservoir pressure and a depletion of oil reserves in the field. Surfactants are employed as a technique in Enhanced Oil Recovery (EOR) to enhance the extraction of oil.

Objective: This study investigates two different forms of surfactant solutions, specifically AOS (alpha olefin sulfonate) and ABS (alkyl benzene sulfonate). The two surfactants were evaluated at five distinct concentration levels, specifically 5%, 6%, and 7%. Both have a salinity level of 7,000 parts per million (ppm). AOS and ABS were selected as research materials because to their capacity to decrease interfacial tension.

Method: A phase behavior test was conducted to assess the durability of the foam throughout a 21-day measurement period at a temperature of 60°C. In addition, the research also seeks to ascertain the efficacy of oil recovery from the surfactant solution under investigation.

Results: This study is a controlled experiment conducted in a laboratory setting to examine the effects of AOS and ABS surfactants on sandstone rocks. The AOS and ABS surfactant solution was prepared by combining AOS powder and 70% ABS surfactant liquid with brine containing a salinity concentration of 7,000 ppm. The research procedure comprises multiple stages, such as density testing and phase behavior testing.

Conclusion: Based on this study, it may be inferred that concentrations beyond 5% did not yield middle-phase emulsions. Nevertheless, the oil recovery rate escalated to 68% as a result of the water flooding injection test and ongoing surfactant injection.

/in /by

Experiment was conducted to determine the effect of marination length of beef se’i with the added of evaporated rosela extract (Hibiscus sabdariffa Linn).  The completly randomized design (CRD) with 4 treatments and 4 replication was applied in this experiment. Those treatments were P0 marination length of 12 hours without roselle extract; P1 marination length 6 hours with 5% roselle extract; P2 marination length 12 hours with 5% roselle extract, and P3 marination length 18 hours with 5% roselle extract. The parameters measured were fat content, fat oxidation and antioxidant activity. Data compilled were analyzed using variance analysis and Duncan’s further test. The result of analysis showed that the addition of roselle extract had significant effect (P<0.05) on antioxidant Activity but no significant effect (P>0.05) on fat content and fat oxidation. The use of 5% roselle extract with a marination time of 6 to 18 hours tends to reduce fat content, slow down the rate of fat oxidation and strengthen antioxidant activity, suggesting that roselle extract is likely to extend the shelf life of beef se’i. It was concluded that the addition of 5% evaporated roselle extract followed by marination for 6 to 18 hours is likely to result in a longer shelf life of sei.
