Abstract

Sub-optimal management of musholla audio systems is often caused by limited technical competence among administrators and the absence of structured standard operating procedures (SOPs). This Community Service program aimed to enhance the self-reliance of musholla administrators at SMA Negeri 1 Jakenan Pati through practice-based training in audio installation and maintenance. The implementation methods included needs-assessment surveys, technical planning, hands-on training, pre- and post-test evaluations, and the development of SOPs for installation, troubleshooting, and periodic maintenance. A total of 20 participants, consisting of musholla administrators and school technical staff, took part in the program. Evaluation results showed an improvement in scores from a range of 40–70 in the pre-test to 62–95 in the post-test. In addition, the quality of the audio installation improved through cable reorganization, signal level adjustment, and equalizer tuning according to room characteristics. The program also produced practical outputs in the form of training modules and operational SOPs. Overall, the results indicate that practice-based training is effective in enhancing technical competence while simultaneously fostering partner self-reliance in managing musholla audio systems.

Abstract

The modulation of rainfall extremes by the Madden–Julian Oscillation (MJO) over Indonesia and the Maritime Continent is well established, but less is known about how consistently this relationship is represented in documented large-scale flood-impact records. This study provides an event-based assessment of active MJO phases 3–5 on high–very high (HVH) rainfall associated with large-scale flood events across seasonal rainfall zones (ZOMs). Flood records from 2008–2024 were linked with reconstructed daily rainfall data from 107 rain-gauge stations and daily Real-time Multivariate MJO index information. Large-scale flood events were defined based on spatial and temporal extent, while HVH rainfall was classified as rainfall above the 75th percentile and evaluated using maximum one-day and five-day accumulated rainfall. The results show that 210 of 577 HVH rainfall-event records, or 36.4%, occurred during active MJO phases 3–5. Active-MJO conditions occurred in 22.2% of one-day HVH rainfall events and 48.6% of five-day accumulated HVH rainfall events. During DJF, active MJO phases 3–5 occurred in 55.1% of five-day accumulated HVH flood-associated events, compared with a seasonal five-day-window baseline of 47.6%, corresponding to a modest enrichment ratio of 1.16. These findings indicate that active MJO phases 3–5 provide complementary information on multi-day HVH rainfall accumulation, although their contribution varies substantially by season and should be interpreted relative to the seasonal background occurrence of the MJO.
