Abstract

Bst DNA polymerase possesses strand displacement activity, enabling isothermal DNA amplification without requiring a thermal cycler. This enzyme is utilized in the Loop-Mediated Isothermal Amplification (LAMP) method, which offers advantages in speed and simplicity over Polymerase Chain Reaction (PCR) method. The growing demand for Bst DNA polymerase highlights the need for cost-effective in-house production, as a commercial option is economically challenging. For that purpose, this study aims to construct and optimize the expression of Bst DNA polymerase from Geobacillus stearothermophilus in Escherichia coli. The expression constructs pET16b.BstHF vector was constructed using Gibson Assembly and expressed in E. coli BL21 (DE3). Optimal expression was achieved with 1 mM IPTG, induction at OD600 0.8 and 6-hour induction time. The purified enzyme was achieved with a protein yield of 2,175 mg/L culture and demonstrated effective polymerase activity for LAMP.

Abstract

This study aims to analyze the inclusive and transformational leadership styles based on gender equality implemented by Khofifah Indar Parawansa in her leadership as the Governor of East Java for the 2025–2030 period. Amid the dynamics of regional development that demand the participation of all societal groups, leadership styles that are responsive to gender equality issues are essential to ensure the realization of social justice and equitable welfare. Using a descriptive qualitative approach through literature review and documentation methods, this article examines the characteristics of Khofifah's leadership, which emphasizes openness, participation, and empowerment of vulnerable groups, especially women. The analysis reveals that Khofifah implemented innovative policies such as the Gender-Responsive Development Planning Forum (Musrenbang Gender), the “Women- and Child-Friendly Village” program, and “Jatim Puspa” (East Java Women's Business Empowerment), which have proven effective in increasing women's participation across various sectors. Additionally, her transformational leadership style is reflected in the strategic program "Nawa Bhakti Satya," aimed at building a more inclusive, just, and sustainable social system. This study concludes that the combination of inclusive and transformational leadership based on gender equality significantly contributes to creating effective, responsive, and equitable regional governance.
