The indicator is the ratio of output productivity, machine productivity levels, productivity ratio of standard working hours, according to the standard output achievement ratio, the ratio of the amount of recovery, the ratio of downtime machine, the ratio of the runtime machine, the ratio of defective raw materials, technological innovation

Pelatihan Prophetic Parenting untuk Menurunkan Stres Pengasuhan pada Ibu dengan Anak Disabilitas Tunanetra

ABSTRACTThis study aims to determine the effect of prophetic parenting training in reducing parenting stress in mothers with children with disabilities. This study involved 7 mothers of children with disability that had parenting stress from the moderate to very high parental stress scores. The seven mothers were divided into two groups, 3 in the experimental group and 4 in the control one. Prophetic parenting training was carried out four times within a two-hour session. Parenting stress was measured using the parenting stress scale from Abidin (Ahern, 2004) adapted by Kurniawan (2012) with a total of 36 items and coefficient α=0.82. Pretest were done before training, posttest 1 was done after training, and posttest 2 was done two weeks after training. The result analysis of friedman test showed that score of p=0.043 (p<0.05). Mann whitney test showed that the measurement of posttes 1 with the score of p=0.054 (p>0.05) and postest 2 with the score of p=0.017 (p<0.05). Hence, it be concluded that the prophetic parenting training has brought the significant effect on the reduction of parenting stress among mothers with the child with disabilities (blind) after getting the time to practice prophetic parenting. The qualitative analisys also supported the result by showing a positive change experienced by each subject in the emotional, behavioral, and spiritual aspect. Keywords: prophetic parenting training, parenting stress, chld with disability (blind)ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh pelatihan prophetic parenting dalam menurunkan stres pengasuhan pada ibu dengan anak disabilitas (tunanetra) Subjek dalam penelitian ini adalah 7 ibu dari anak disabilitas tunanetra yang memiliki skor stres pengasuhan dengan kategori sedang hingga sangat tinggi.
