Abstract

The commercially important red seaweed Kappaphycus alvarezii is extensively cultivated for carrageenan production. Despite its economic value, large-scale reproduction and genetic enhancement remain limited due to its low regeneration potential. This study aimed to optimize plant growth regulator (PGR) concentrations for efficient callus induction in K. alvarezii. A completely randomized design was employed, comprising five treatments with varying concentrations of indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP), along with a control lacking PGRs. A total of 180 explants from meristematic tissues of acclimatized thalli were cultured (30 explants per treatment). The highest callus induction rate (88%) was achieved with 1.50 mg/L IAA and 5 mg/L BAP (Treatment F), with visible callus formation beginning around day 38. A progressive color change from brown to white was observed, indicating active cellular proliferation. Other treatments exhibited lower induction rates, ranging from 0% (control) to 61% (Treatment D). These findings underscore the critical influence of auxin–cytokinin interactions on callogenesis and offer an optimized hormonal regime for improving in vitro culture efficiency. The established protocol provides a valuable platform for future large-scale propagation and genetic improvement strategies in K. alvarezii, contributing to the advancement of seaweed biotechnology.

Abstract

The financial level of a country will encourage the development of the country's economy. Internal and external factors cause high and low financial management behavior. This study aims to develop a model that examines the three variables that the author has analyzed to determine the factors that can increase student interest in saving. This study used an associative descriptive quantitative method with a population of 102 respondents drawn into a sample using non-probability sampling, using saturated sampling / total sampling method. Data analysis techniques using linear regression with the help of SPSS software version 26. The first hypothesis of knowledge significantly affects students' interest in saving, the second hypothesis of financial literacy variables has a significant impact on students' interest in saving, and the third hypothesis of knowledge and financial literacy together can affect students' interest in saving. This research is expected to make theoretical contributions to the literature in this context, including in the context of financial and banking management.
