Abstract

The prospect of A. calamus extract to be botanical insecticides to control the insect pests is very promising. The insect control properties of the A. calamus are predominantly to have β-asarone, saponin and flavonoid. However, there are some factors limiting their efficacy. Short release rate at the point contact, the inherent volatility and vulnerability to oxidation and ultra-violet light are causing phytochemical changes during the application. Thus developing nanotechnology to increase their efficacy studied in this research. To develop the plant extract in nanoformulation, experiment on adsorption and desoption capacity were carried out with Acorus extract treated bentonite substrate analysed by GC techniques. In addition, to investigate the effectiveness of the plant extract treated bentonite were evaluated on Crocidolomia pavonana. Third instar larvae were used in the evaluation of antifeedant effect by using no choice methods. The results showed that Bentonite nanoparticles was effective in controlling the release of a bioactive element. Purifed clay bentonite for getting Na-bentonite increased the specific surface area of material therefore increased the adsorption site on the clay layer of the material. Crude extract of A.calamus can dissolve well in combination of water and organic solvents. Desorption experiments proved that Na-bentonite released more slowly than raw clay bentonite. Purification of bentonite to Na-bentonite resulted the changing of phytochemical properties bentonite which lead to an increase in the adsorption capacity of bentonite. In term of antifeedant evaluation based on damage to cabbage leaves seedling, the least damage was observed on leaves with nanoparticle plant extract formulation. The antifeedant index of A. calamus in nanoparticles formulation showed 25% higher that untreated cabbage plant seedling. The glasshouse trial was conducted to evaluate their efficacy on cabbage seedling. However, the brown leaves or phytotoxic effect has been found by the time the extracts nano formulation has been sprayed.

Abstract

This study examines the role of simple lifestyle in mediating the effect of financial literacy and self-control on financial behavior. This survey design study involved 126 samples of undergraduate accounting students at Pamulang University. Using the Structural Equation Modeling (SEM) Partial Least Squares estimator method, this study found a positive effect of financial literacy on simple lifestyle. This study also found that financial literacy and self-control directly affect financial behavior. However, this study found no effect of a simple lifestyle on financial behavior. In addition, this study failed to prove the role of simple lifestyle in mediating the indirect effect of financial literacy and self-control on financial behavior. These results indicate that financial literacy and self-control are the most dominant factors in improving students' financial behavior. On that basis, higher education institutions should encourage the strengthening of financial literacy and self-control of students more intensively in order to improve their financial behavior. Good financial behavior in this context is a person's ability to organize, manage, and use their financial resources more wisely and rationally.

Abstract

This study aims to analyze the influence of leadership style and work motivation on the performance of civil servants (PNS) at the Office of the Domestic Policy Strategy Agency (BSKDN) in Central Jakarta. The study employs a descriptive quantitative approach using a survey method, where data were collected through questionnaires distributed to a number of PNS within BSKDN. The collected data were then analyzed using multiple linear regression with the aid of statistical software to examine the relationships and effects between variables. The results indicate that leadership style has a substantial and positive effect on PNS performance, suggesting that effective, inspiring, and communicative leadership can enhance employee productivity and work quality. Moreover, work motivation also demonstrates a positive and significant impact on PNS performance, indicating that highly motivated employees exhibit greater dedication, discipline, and initiative in carrying out their duties. Further analysis shows that when leadership style and work motivation are applied simultaneously, both provide a substantial influence on improving PNS performance, emphasizing the importance of synergy between good leadership and employees’ internal motivation. The practical implications of this study underscore the urgency for BSKDN to develop leadership training programs that can inspire, motivate, and empower employees comprehensively. Additionally, designing sustainable strategies to enhance work motivation is also crucial to optimize the performance of all PNS within BSKDN, ensuring organizational goals are achieved effectively and efficiently. This study contributes to the development of human resource management practices in the government sector, particularly in the context of enhancing employee performance through the combination of effective leadership and optimal work motivation.
