Hasil Penelitian ini didapatkan grafik Intensitas hujan selama 24 jam untuk periode ulang 2, 8, 10, 20, 50 dan 100 tahun dan debit banjir maksimum DAS Gonjol yang didapat adalah Q2 (43,77m3/sec) , Q5 (51,73 m3/sec), Q10 (55,95 m3/sec), Q20 (59,40m3/det), Q50 (63,23 m3/sec), Q100 (65,87 m3/sec)

This study aims to analyze the effect of work motivation and organizational culture on job satisfaction and its impact on employee performance at the BMKG Malang Climatology Station. The research method used is quantitative with an explanatory research approach. Data were collected through questionnaires distributed to 37 employees using a census technique. Data analysis was conducted using path analysis with SPSS version 20. The results show that work motivation has a positive and significant effect on job satisfaction (? = 0.386; p = 0.011). Organizational culture also has a positive and significant impact on job satisfaction (? = 0.446; p = 0.004). Both work motivation and organizational culture have a positive effect on employee performance, with coefficients of 0.311 (p = 0.015) and 0.266 (p = 0.042), respectively. Job satisfaction significantly influences employee performance (? = 0.405; p = 0.004). The indirect effect of work motivation and organizational culture on performance through job satisfaction is 15.6% and 18.1%, respectively. In conclusion, enhancing work motivation and organizational culture can improve employee performance both directly and through job satisfaction.
