Abstract

Seaweed has potential as a commodity for small and medium-scale businesses, but its quality is low due to conventional drying which experiences contamination and dries slowly. This research aims to produce a prototype IoT-based seaweed dryer to improve the quality of seaweed. The stages of this research are designing a prototype drying device, drying seaweed tests, and proximate analysis of seaweed. This research resulted in a 300W prototype using IoT components, including a solid state relay, Arduino Uno R3, potentiometer, thermocouple, 12C LCD, and SIM 800L V2 GSM GPRS module, with temperature control via an Android application. Optimal drying occurs at 60 oC, producing dried seaweed weighing 470.90 g from 1000 g. Water content decreases as temperature increases to 60 oC (18.85%), 50 oC (23.11%), 40 oC (32.30%), and conventional (34.50%). The highest protein, fat and carbohydrate content was at 60 oC, indicating drying efficiency at that temperature. Based on these results, it was concluded that using a dryer with a temperature of 60 oC was the best and most efficient.Keywords: Dryer; IoT; production; proximate; seaweed

Abstract

This study examines the role of financial management as a mediating variable in the relationship between financial literacy, income, lifestyle, and investment decisions. Grounded in financial literacy theory, personal financial management theory, and behavioral finance, the research proposes and empirically tests a conceptual model using Partial Least Squares–Structural Equation Modeling (PLS-SEM). Data were collected from all 155 employees of the Smart City & Community Innovation Center (SCCIC) using a structured questionnaire measured on a five-point Likert scale. The results reveal that financial literacy and income do not have a direct effect on investment decisions; however, both variables significantly influence financial management. Financial management, in turn, has a very strong and significant effect on investment decisions and fully mediates the relationships between financial literacy and investment decisions, as well as between income and investment decisions. Conversely, lifestyle shows no significant direct or indirect effect on either financial management or investment decisions. The model demonstrates strong explanatory power, with an R² value of 0.924 for investment decisions and a Goodness of Fit (GOF) index of 0.571. These findings highlight financial management as the key mechanism through which financial knowledge and financial resources are transformed into effective investment behavior. The study contributes to the literature by emphasizing the central role of financial management in investment decision-making within a professional organizational context and offers practical implications for financial education and organizational financial capability development.
