Abstract

Sales performance differs notably among individuals, yet each salesperson plays a crucial role in achieving organizational targets. These differences can be influenced by various factors, including job insecurity and job experience. This study investigates how job insecurity and job experience affect job performance, with work engagement as a mediating factor, focusing on car salespersons in Kebumen Regency. Using a quantitative approach and Partial Least Squares–Structural Equation Modeling (PLS-SEM), data were collected from 62 respondents. The results reveal that job insecurity has no significant impact on work engagement or job performance. In contrast, job experience positively and significantly affects both work engagement and performance. Mediation analysis shows that work engagement significantly mediates the effect of job experience on performance, but not for job insecurity. These findings highlight that while work engagement can amplify the benefits of job experience, it does not counteract the negative effects of job insecurity. Managers are thus advised to enhance work engagement and

Abstract

The aim of this research is to examine the influence of the non-physical work environment and servant leadership on employee performance in the Nusakambangan open prison, with motivation as a mediating variable. Servant leadership emphasizes a leadership style that prioritizes service to subordinates, while the non-physical work environment includes psychological and social aspects that can affect employee comfort and productivity. This descriptive study used a quantitative approach. This study involved 68 people working at the Nusakambangan Open Prison. Sampling saturation was used to cover the entire population, consisting of 68 employees. In this study, interviews, observations, and questionnaires were used to collect data. Structural Equation Modeling (SEM) or Partial Least Squares (PLS) was used to conduct data analysis. The research findings indicate that servant leadership has an impact on motivation, as does the non-physical work environment; both affect performance through motivational mediation. The results suggest that a leadership style that prioritizes service and a psychologically supportive work environment can increase employee motivation, which in turn can lead to better performance.

Abstract

The problem of food waste management, which continues to increase and dominate the composition of waste, necessitates circular economy-based solutions that not only solve the problem of waste accumulation but also provide economic benefits. One such solution is the cultivation of Black Soldier Fly (BSF) maggots, as maggots can reduce food waste by 90%. One of the businesses that cultivates BSF maggots is Bumi Farm, but since its establishment in 2020, no financial feasibility evaluation has been conducted. Therefore, this study aims to evaluate the financial feasibility of BSF maggot cultivation at Bumi Farm using NPV, IRR, PP, and Net B/C. The results of this study indicate that the BSF maggot cultivation business at Bumi Farm shows the following values NPV with a Bi Rate of 5.75% is IDR 152,700,000, which is considered feasible because the NPV value is > 0; IRR value of 36.71% is considered feasible because the IRR value is > Bi Rate; The Payback Period of 2 years and 10 months is feasible because the PP value is < Economic Life, and the Net B/C of 2.32 is feasible because the Net B/C value is > 1. The results of the analysis show that all financial feasibility indicators are met, so that the BSF Maggot Cultivation business at Bumi Farm is feasible to run because it meets all financial feasibility indicators

Abstract

This study examined the determinants of micro, small, and medium-sized enterprise performance, focusing on financial inclusion, financial literacy, and financial management capability in Karang Berombak Subdistrict. The research problem addressed the extent to which these financial factors contributed to improving enterprise performance. A quantitative research approach was applied, and data were collected through structured questionnaires distributed to micro, small, and medium-sized enterprise owners. The sample consisted of 86 respondents. Descriptive statistical analysis and multiple linear regression analysis were used to examine the relationships between financial inclusion, financial literacy, financial management capability, and enterprise performance. The findings showed that financial inclusion had a significant effect on micro, small, and medium-sized enterprise performance, indicating that access to financial services supported business growth and operational effectiveness. Financial literacy also had a significant effect on enterprise performance, suggesting that financial knowledge played an important role in business decision-making. However, financial management capability did not have a significant effect on enterprise performance. These results implied that while access to financial services and financial knowledge were critical determinants of enterprise performance, financial management capability alone was not sufficient to improve performance. The study concluded that strengthening financial inclusion and financial literacy was essential to enhance micro, small, and medium-sized enterprise performance in Karang Berombak Subdistrict

Abstract

The diversity of characteristics among Micro, Small, and Medium Enterprises (MSMEs) often poses a challenge for effective policy formulation, where a one-size-fits-all approach fails to distinguish the specific needs of each business. This study aims to overcome the limitations of administrative segmentation by applying a new behavior-based framework, namely LSE (Longevity, Scale, Employment), to characterize the typology of MSMEs in the city of Semarang. The research method adapts the principles of Recency, Frequency, Monetary (RFM) into business metrics: Longevity (resilience), Scale (maturity), and Employment (socio-economic impact). Using data sourced from the Semarang City Cooperative and MSME Office, this study analyzed 8,804 valid MSME data points through a K-Means Clustering algorithm optimized with the Elbow Method. The results identified three distinct clusters: Sustainable Businesses, Accelerative Businesses, and Stagnant Micro Businesses. These findings validate the effectiveness of the LSE model in mapping business heterogeneity and recommend a paradigm shift in policy towards targeted and relevant interventions for each segment.

Abstract

Employees were considered critical organizational assets that required professional management to ensure optimal contributions to organizational sustainability and development. One important form of contribution was prosocial voice behavior, defined as employees’ willingness to express constructive ideas, opinions, and suggestions to organizational authorities. Such behavior functioned as a positive indicator of organizational effectiveness, whereas employee silence reflected the opposite condition. Accordingly, identifying factors that fostered prosocial voice behavior was essential. This study aims to examine the effect of transformational leadership on prosocial voice behavior through the mediating role of psychological ownership. The study further explored this mediating mechanism within governance practices of public education institutions, both state-owned and private, in Indonesia. A quantitative cross-sectional design was employed, involving 194 respondents drawn from employees of public and private formal education foundations who had worked for more than one year and were not currently bound by permanent employment contracts with other organizations. Primary data were collected through self-administered online questionnaires. Structural Equation Modeling was applied to test the proposed hypotheses. The results reveal that transformational leadership has a statistically significant and positive effect on prosocial voice behavior. In addition, psychological ownership partially mediated the relationship between transformational leadership and prosocial voice behavior. While previous studies had examined various antecedents of prosocial voice, this study extended the literature by highlighting the role of psychological ownership in the educational sector. The findings offered practical implications for foundations and similar organizations and contributed empirical evidence to the literature on transformational leadership, psychological ownership, and prosocial voice behavior.
