Performance Management and Student Mathematic Disposition through a Posing Problem Approach

This study aims to determine the performance management and mathematical disposition of students through the problem posing approach. This research uses quasi experimental research. The population in this study were 149 students of SMK Sumber Mulyo. The research sample was the cluster random sampling technique (random group sample), that is, one class was selected as a sample subject to treatment through random selection, namely students of class XI SMK TSM totaling 30 students. The results showed that the level of influence between the problem posing approach variable on performance management and students' mathematical dispositions had a high effect. The results of testing the research hypothesis testing problem posing approach to performance management can be seen that the tcount value is 7.560 and ttabet is 1, 781 so that tcount ≥ ttable then Ha1 is accepted, that is, there is a positive and significant influence between the problem posing approach to performance management. Furthermore, the results of the research hypothesis test of the problem posing approach to mathematical disposition, it is known that the tcount value is 6.630 and the t table is 1.981 so that tcount ≥ ttable then Ha2 is accepted, namely that there is a positive and significant influence between the problem posing approach to mathematical disposition.

One of common problems associated with breastfeeding is breast engorgement. This breast swelling can cause the mother to stop breastfeeding. This study aims to determine the effect of cabbage compresses on reducing breast engorgement in postpartum mothers at Kasih Ibu Primary Clinic in Deli Tua in 2019. The research used quasi-experimental, one-group pretest-posttest method design. The sampling technique used convenience sampling to recruit 30 postpartum mothers who had breast engorgement. The instrument used to measure breast swelling was the breast engorgement assessment scale of Hill and Hummenick which consisting of a scale of 1 to 6. Application of cabbage compresses was done by attaching cabbage to the breast until the cabbage withers. This procedure was repeated four times every 6 hours per day, for 2 days. The results of the study showed that at the time before being compressed all the research subjects had a score of 4. On the 1st day of compressing with cabbage leaves, there were 7 people (23.3%) who had decreased breast swelling and on the 2nd day of compressing, the total postpartum mothers experienced a decreased in breast engorgement was 9 people (30%). Statistical analysis by paired t-test obtained the value of p = 0.001 (p <0.05). Thus, the results of this study concluded that there was a significant influence of cabbage compresses to decrease breast engorgement of the postpartum mothers at Kasih Ibu Primary Clinic in Deli Tua in 2019.
