Abstract

This study aimed to evaluate the effects of energy and organic zinc supplements, specifically zinc palm oil soap (ZPOS), on digestibility and unsaturated fatty acid profiles in vitro. The study used a completely randomized design with 4 treatments and 5 replications. The treatments were: T0= basal diet without supplementation, T1= basal diet + 5% palm oil (PO), T2= basal diet + 5% partial ZPOS (3.75% ZPOS + 1.25% PO), and T3= basal diet + 5% ZPOS. The inoculum source was rumen liquid from three fistulated female dairy goats and was homogenized. The goats were fed ration consisting of corn straw, soybean hulls, and concentrate containing total digestible nutrients (TDN) 63%, crude protein (CP) 14%, and neutral detergent fiber (NDF) 35%. Results showed that both 5% partial ZPOS and 5% ZPOS supplementation (T2 and T3) resulted in the increase of total volatile fatty acids (VFA), acetate, propionate, butyrate, unsaturated fatty acids (USFA) and a decrease in the ratio of acetate/propionate (A/P) compared to the control and supplementation of 5% PO (p<0.05). Supplementation of 5% partial ZPOS (T2) is better than 5% ZPOS because increased the digestibility of ether extract (EE), crude fiber (CF), NDF, and acids detergent fiber (ADF) (p<0.05) and decreased of methane compared to the control (p<0.05). In conclusion, adding 5% partial ZPOS (3.5% ZPOS and 1.5% PO) increases fiber digestibility, VFA, LCFA, and USFA concentration, and decreases methane production in the rumen liquid.

Abstract

This study examines how Islamic work ethics and quality of work life affect employee performance, using Sultan Agung Islamic Hospital in Semarang as a mediating variable. One hundred workers completed questionnaires for the quantitative study, which was then evaluated using the Sobel Test and multiple linear regression. The findings show that Islamic work ethics and quality of work life have a positive impact on employee engagement and performance, while employee engagement has a positive impact on performance but has not been able to mediate the relationship between the two variables and performance. It follows that balancing technical, spiritual, and work-life factors is necessary to improve performance. It is anticipated that Sultan Agung Islamic Hospital would keep enhancing the standard of living and Islamic principles. For more general findings, more study with more variables and a wider variety of participants is advised.

Abstract

This study was motivated by the low level of business readiness among some micro, small, and medium enterprises (MSMEs) in facing an increasingly digital, competitive, and complex business environment. This study aimed to analyze the effect of visionary leadership and technological adaptability on business readiness, both directly and through the mediating role of digital transformation. This study employed a quantitative approach with a survey design. Data were collected through questionnaires administered to MSME actors in Grobogan Regency and were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with the assistance of SmartPLS 4.0. The results showed that visionary leadership and technological adaptability had a positive and significant effect on business readiness. In addition, digital transformation was proven to have a positive effect and to mediate the relationship between visionary leadership and technological adaptability and business readiness. These findings confirm that visionary leadership, technological adaptability, and effective implementation of digital transformation are key factors in improving MSME business readiness. The implications of this study emphasize the importance of strengthening leadership capacity, improving technological literacy, and accelerating digital transformation through targeted policy support and training for MSME actors.

Abstract

Improving employee performance is an important issue in manufacturing companies, particularly because of differing findings in previous studies regarding the influence of competence and intrinsic motivation on employee performance. This study aims to analyze the effect of competence and intrinsic motivation on employee performance, with job satisfaction as a mediating variable among employees of PT Formosa Bag Indonesia. This study used a quantitative approach with an explanatory research design. The research sample consisted of 100 employees selected through purposive sampling. Data were collected through questionnaire distribution using a Likert scale and analyzed using the Partial Least Squares (PLS) method. The results show that competence and intrinsic motivation have a positive effect on job satisfaction and employee performance. In addition, job satisfaction was proven to mediate the effect of competence and intrinsic motivation on employee performance. These findings confirm that improving competence and intrinsic motivation can strengthen job satisfaction, which ultimately has an impact on improving employee performance. This study contributes to the development of human resource management studies, particularly regarding the role of job satisfaction as a mediating mechanism in the relationship between competence, intrinsic motivation, and employee performance. The practical implications of this study emphasize the importance of competence development, strengthening intrinsic motivation, and creating a work environment that supports job satisfaction to improve employee performance in manufacturing companies.
