Abstract

Penelitian ini bertujuan untuk melihat pengaruh intellectual capital (VAICTM) terhadap financial performance (profitabilitas, produktivitas, dan penilaian pasar). Profitabilitas diukur dengan Return on Equity (ROE), produktivitas diukur dengan Asset Turnover (ATO), dan penilaian pasar diukur dengan Tobin’s Q. Sampel penelitiannya menggunakan data perusahaan jasa yang diperoleh dari Bursa Efek Indonesia untuk periode 2010-2013. Hasil penelitian menunjukkan bahwa capital employee yang paling berperan digunakan oleh perusahaan sampel untuk meningkatkan profitabilitas dan produktivitas.

Abstract

Dengue fever remains a significant public health concern in tropical regions, particularly in Southeast Asia. This cross-sectional study aimed to assess the prevalence and risk factors of dengue fever among children in Makassar, Indonesia. A total of 400 children aged 0-14 were surveyed, and data were collected on socioeconomic status, environmental conditions, and preventive behaviors such as mosquito net use. The overall prevalence of dengue was 25.8%, with higher rates observed in low-income households and those with standing water. Children from low-income families had a dengue prevalence of 26.8%, while the prevalence in high-income households was 23.5%. Households with standing water had a significantly higher dengue prevalence (30.2%) compared to those without (22.7%). Inconsistent mosquito net use was associated with higher dengue rates, with children in households that sometimes used nets having the highest prevalence (28.3%). These findings highlight the importance of addressing environmental and socioeconomic factors in dengue prevention strategies. Public health efforts should focus on community education, eliminating breeding sites, and promoting consistent use of preventive measures to reduce dengue transmission.

Abstract

This study aimed to evaluate the potential of the active fraction from Vigna radiata L. sprout extract as a natural bioregulator in the in vitro culture of Nepenthes sp. plantlets using Murashige & Skoog (MS) medium. The use of natural plant growth regulators offers an alternative to reduce dependence on synthetic growth regulators, particularly for carnivorous plants that generally exhibit slow growth rates and sensitive responses in tissue culture. The active fraction was obtained through stepwise fractionation to isolate bioactive compounds that may stimulate plant growth. Plantlets were cultured on MS medium supplemented with various concentrations of the active fraction to observe growth responses, including shoot elongation, leaf number, root development, and overall biomass accumulation. The results are expected to identify the optimum concentration that provides the highest growth stimulation, demonstrating that Vigna radiata sprout extract can serve as an efficient, economical, and environmentally friendly natural bioregulator. These findings contribute to the development of improved propagation protocols for Nepenthes sp. and highlight the potential of sprout-derived natural compounds for broader applications in plant tissue culture.
