This study aims to determine the effect of adding EM4 probiotics in various doses to commercial feed on the growth of jatimbulan tilapia (Oreochromis niloticus L). Probiotics are known to play a role in increasing digestive efficiency, nutrient absorption, and maintaining the health of the fish's digestive tract, so they are expected to support optimal growth. The research method used was a Completely Randomized Design (CRD) with four treatments, namely: P0 (control/without probiotics), P1 (5 ml EM4/kg feed), P2 (7 ml EM4/kg feed), and P3 (11 ml EM4/kg feed), each with four replications. The parameters observed were the growth in length and weight of jatimbulan tilapia during the maintenance period. The results showed that the administration of EM4 probiotics at certain doses was able to provide a significant effect on the growth of tilapia compared to the control treatment. Treatment P2 (7 ml/kg feed) provided the best growth results compared to other doses, both in terms of increasing length and body weight. Meanwhile, administering probiotic doses that are too low (P1) or too high (P3) tends to be less effective in supporting optimal growth. This is thought to be due to the disruption of the microbial balance in the digestive tract when the probiotic dosage is incorrect. This research provides useful information for Jatimbulan tilapia cultivation practices, particularly regarding the use of probiotics to increase growth efficiency. Using the correct probiotic dosage can be a strategy to increase the productivity and sustainability of freshwater fish farming.

In the face of increasingly fierce and complex organizational competition, this allows organizations to change the management pattern strategy that is played especially in increasing optimal performance through the role of human resource management because it is human resources who have a mindset through ideas, opinions, as well as views that are not shared by other resources. Employees are human resources who hold the most important position in implementing an organisation's vision, mission and goals. Employee performance is one of the markers that need to be considered by the organization. When employees feel unmotivated at work, this will have an impact on inhibiting organizational operational activities. Therefore, one strong indicator of influencing the environment is the presence of a leader. There are many styles preferred by employees, one of which is the transformational leadership style, especially in the current digitalization era. This writing aims to understand and explore the influence of transformational leadership style on employee performance. The method used is a Systematic Literature review using secondary data, where the author collects data related to the theme, and information is taken from various Scopus-indexed journals. The results of the study suggest that the transformational leadership style can affect the performance of employees in the organization. Because employees are actively involved, they feel increased motivation, increased trust, willingness to follow philosophy, ideology, vision, and increased consequences of interesting change. They have high commitment and can see one's abilities. Employees who are inspired by transformational leadership are also more likely to immerse themselves in work, resulting in better task performance and helping behaviours that ultimately help build organizational progress
