<![CDATA[This study aims to measure the effectiveness of using big clock media in improving grade 1 elementary students' understanding of the concept of reading analog clocks. The research method used is a quantitative method with a pretest-posttest design to compare the results of students' initial and final tests after learning using large clock media. This research was conducted at SDN Pabian 4, with five students as samples. The results showed an increase in students' understanding of analog clock reading material, as indicated by the increase in the average score from the initial test of 36% to 84% in the final test. This finding emphasizes the importance of using concrete media in learning mathematics, especially for abstract materials. This research is expected to encourage further innovation in the development of creative and applicable educational media, as well as provide insight for educators in optimizing the teaching and learning process.]]>

<![CDATA[Domestic violence is a national issue that shows an increasing trend in cases from year to year. This study aims to empirically test the effectiveness of Cognitive Behavioural Group Therapy in reducing depression in female survivors of domestic violence. This study used a quasi-experimental design with a pre-test-post-test control group design model. The number of respondents in this study was 16 participants, divided into eight respondents in the experimental group and eight respondents in the control group. The experimental group (n = 8) received Cognitive Behavioural Group Therapy intervention, while the control group (n = 8) was on the intervention waiting list. The level of depression was measured by the Patient Health Questionnaire-9 (PHQ-9) before the intervention, after the intervention, and two weeks after the post-intervention follow-up. The results of the analysis with the independent sample t-test showed a significant difference in the mean depression score between the control and experimental groups in the post-test phase (after being given Cognitive Behavioural Group Therapy), with a p-value of 0.000 (p <0.05). In conclusion, this research proves that Cognitive Behavioural Group Therapy is effective in reducing depression in female survivors of domestic violence. Cognitive Behavioural Group Therapy interventions have an impact on depression levels even after the intervention sessions have ended (as evidenced by the measurement of depression scores in the follow-up sessions).

<![CDATA[The development of digital story conceptual change-oriented (DSCC) has been implemented to reduce the number of students' misconceptions. In this study, DSCC is reviewed based on the story aspect. This experimental design study used a one-group pretest-posttest design. The sampling in this study was taken by a purposive technique involving 114 students from two districts. The diagnostic instrument used was four tier-test and rubrics for assessing the story aspect of DSCC. In determining the decrease of the students' misconceptions, the researchers use the DQM formula. The analysis of DSCC’s assessment result was done using a holistic method. The result of the study shows that there was a decrease in the number of students' misconceptions within the high category. The highest number of the student who decreases after the implementation of DSCC was 100% and that statement of misconception was: "every motionless object has no energy". On the other side, the result of the story aspect assessment shows that there was 20% of students gave negative comments for DSCC’s sequence/chronology events and 10% of the state that the location/ plotting of places was inappropriate(out of character). It is recommended for further research to consider the learning model to optimize the minimalization of the number of students' misconceptions.]]>

<![CDATA[The shrimp nursery infrastructure consists of nursery tanks, mechanical filters, biological filters, and ultraviolet (UV) filters. This study aimed to simulate the water level elevation (head) of shrimp nursery infrastructure, especially nursery tanks. The placement of the nursery greatly affects the elevation of the water table owing to the loss of energy (headloss) that occurs in the flow. The nursery tub used in this study was round and consisted of four tubs made of fiber resin measuring 250 cm in diameter and 120 cm in height. The bottom of the tub was placed at an elevation of +40 cm above the ground. The simulation was conducted for 24 hours. The results of the EPANET 2.2 simulation showed head fluctuations in each nursery with the highest elevation (1.38 m and the lowest (1.20 m, from the data. The head fluctuated constantly after 6 h of the flow. The optimal pipe diameters were 3" (80 mm) PVC and 4" (110 mm) PVC.]]>
