This research attempted to determine the important factors influencing on effective leadership. To understand the vital role of leadership in business for improving performance and productivity in business, the aim of this article was to investigate some critical factors to become a good leader in terms of students. This research applied quantitative approach to validate the hypothesis. I gather information from 200 students range from 18-22 years old by questionnaire in the University of Finance - Marketing on Pho Quang Street, Tan Binh District. It was concluded the factors that strongly affected on the successes of a good leader. Not only factors that we can see obviously, besides that, through some main factors directly affected on the features of a good leader like trust, motivation, learning and learning, organizational culture, teamwork and communicational skills. The limitation of this research relates to the small size of sampling, inadequate literature review and lack of considering environmental impact on individuals. The future research will attempt to gather more literature review and enlarge the sample size, while trying to analyze based on practical evidence.

This study explores the adsorption of doxycycline (DOX) from aqueous solutions onto biochar derived from banana peel, which was prepared using a potassium hydroxide activation method (KOH-BPB). The biochar properties were characterized based on morphology, surface area (SBET of 710.241 ㎡ g<SUP>−1</SUP>), functional groups, and surface charge (pHPZC = 7.7). Parameters, including initial pH, DOX concentration, and ionic strength, that influenced the DOX adsorption capacity of KOH-BPB were examined. Adsorption equilibrium of DOX on KOH-BPB was assessed through four isothermal models: the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich models. The obtained data were most compatible with the Langmuir model (R² = 0.9879). KOH-BPB has a maximum DOX absorption capacity of 121.95 mg g<SUP>-1</SUP> which exceeds that of many comparable absorbents. The maximum DOX removal was 96.7% at pH 6, a DOX concentration of 20 mg L<SUP>-1</SUP>, and a KOH-BPB dose of 1.0g L<SUP>-1</SUP>. These findings reveal that biochar from banana peel effectively removes antibiotic residues from water. This study provides a potential, low-cost, and environmentally friendly adsorbent.
