This research aims to analyze the influence of commitment, leadership and individual character on employee work motivation in the Provincial Women's Empowerment, Child Protection and Family Planning Service. South Kalimantan, this is indeed crucial and significant in achieving organizational goals, so as to improve the performance of employees in the SKPD environment in the South Kalimantan provincial government. This research method uses a qualitative method, using SPSS version 24, data and data sources obtained from independent variables, namely Commitment (X1), Leadership (X2) and individual characteristics (X3) and Work Motivation (Y). Data analysis techniques are carried out using Descriptive Analysis, Classical Assumption Test, Multiple Linear Regression Analysis, Hypothesis Testing, both Persial t Statistical Tests, F Stimulant Statistical Tests, Determination Coefficients and Reliability Validity Tests. The research results show that the implications of the research results show that commitment, leadership and individual characteristics can influence the motivation of employees of the Provincial Women's Empowerment, Child Protection and Family Planning Service. South Kalimantan, can increase employee motivation through organizational leaders who continue to encourage their employees by providing guidance and direction consistently and continuously.

Tujuan penelitian ini adalah mengetahui pengaruh iradiasi sinar Gamma terhadap karakter morfologis (jumlah daun, bentuk daun, jumlah cabang, panjang cabang, diameter bunga, bentuk dan warna bunga juga warna batang) dan karakter anatomi (kerapatan stomata permukaan atas daun, struktur anatomi daun dan). ). struktur anatomi batang). Penelitian ini merupakan penelitian eksperimental dengan Rancangan Acak Lengkap (RAL). Tahap pertama yaitu iradiasi terhadap batang krokot dengan dosis 0, 10, 20, 30, 40 dan 50 Gy. Tahap kedua yaitu analisis data jumlah daun, jumlah cabang, panjang cabang, diameter bunga dan kerapatan stomata permukaan daun dengan One Way ANOVA dan uji Duncan (DMRT) dengan aplikasi SPSS 16.0.Hasil penelitian menunjukkan bahwa iradiasi sinar Gamma berpengaruh nyata terhadap jumlah daun, bentuk daun, jumlah cabang, kerapatan stomata permukaan atas daun, warna dan bentuk bunga, juga warna batang, namun tidak berpengaruh nyata terhadap panjang cabang, diameter bunga, struktur anatomi daun, struktur anatomi daun. Dosis 30 Gy memberikan hasil yang paling bervariasi terhadap bentuk dan warna bunga.

Artisanal gold mining activities in Indonesia often cause mercury (Hg) pollution, which is toxic and bioaccumulative. Phytoremediation using Pteris vittata L. as a hyperaccumulator and rhizobacteria Pseudomonas aeruginosa RTKP1 is an alternative to overcome this problem. This study aimed to analyze the effect of combined treatment of Pseudomonas aeruginosa RTKP1 induction and compost on the ability of Pteris vittata L. to accumulate Hg in gold mine tailings. The treatment consisted of bacterial induction without compost, and with compost at a tailings:compost ratios of 1:1 and 2:1. This study used descriptive and quantitative analyses. The results showed that Pseudomonas aeruginosa RTKP1 induction without compost resulted in the highest reduction in Hg levels in the tailings, from 10.7 mg/kg to 0.00467 mg/kg with a medium-high BCF value and TF <1, indicating a phytostabilization mechanism. However, the addition of compost reduced the effectiveness of bioaccumulation. Hence, treatment of Pseudomonas aeruginosa RTKP1 without compost was most effective in increasing the ability of Pteris vittata L. to reduce mercury content.
