Muara Bungo Main Substation is one of the main substations in the working area of ??PT. PLN (Persero) UPT Jambi. This substation is located along the Sungai Binjai, Batin III District, Bungo Regency, Jambi Province. The Power Transformer 1 cubicle panel at this substation often experiences problems with insulation defects which can cause interference with electricity transmission. In this research, the transient earth voltage method is applied, which functions as a sensor to detect partial discharge signals in high voltage equipment. The sensor used to measure transient ground voltage is a capacitive sensor. This testing can be done directly (online) without disrupting operations. The measuring instrument used in partial discharge testing is the Ultra TEV Plus 2.The results of partial discharge testing using the transient earth voltage method show that most of the panels and their components, especially panel TD No. 1, in good condition. However, there is one component, namely the circuit breaker (PMT), which shows the highest partial discharge value. Tests on Palem feeder cubicles showed the highest TEV value of 12 dB and PPC of 4.62 for the PMT component. Overall, the measured TEV values ??ranged from 10 to 19 dB, and the PPC ranged from 0.5 to 6, indicating that the Palem feeder cubicles were classified as low-level PD. Based on these results, every PMT component in the field needs to be checked thoroughly and repairs planned if there are problems with the PMT material.

This study explores the construction of humanistic leadership and the concepts of cross-generational collaboration and reverse mentoring, psychological well-being as a mediator, and innovative academic productivity as a dependent. The focus of the study is private universities in Central Java. The methodology used is a mixed method approach, where quantitative data were collected through questionnaires distributed to 390 lecturers. Then, the data were analyzed using structural equation modelling facilitated by AMOS software version 24.00. Qualitative data were obtained through interviews and FGDs, with the analysis process involving triangulation and coding supported by NVivo software. The findings of the study concluded that there was a significant interaction between the exogenous and endogenous variables. However, the role of psychological well-being is only a partial mediation, not a full one. Therefore, this comprehensive approach highlights the critical role of various leadership styles and collaborative methodologies in promoting innovative academic behaviour. This finding also explains how important local culture is as inspired by the educational figure Ki Hajar Dewantara through his concept of “ing ngarso sung tuladha, ing madya mbangun karsa, tut wuri handayani” which greatly supports higher education in encouraging innovative behaviour through knowledge sharing, which has an impact on increasing academic productivity in higher education.
