This study aims to determine the effect of the Concrete Pictorial Abstract learning approach on student learning outcomes in Mathematics content in class III SDN 110/I Desa Tenam. This research was conducted in class III at SDN 110/I Tenam Village for the 2022/2023 academic year. This research is a quantitative study using quasi-experiments. The data was processed to compare the results of the pre-test and post-test in the experimental class and the control class. The results showed that learning Mathematics using the Concrete Pictorial Abstract approach for class III SDN 110/I Desa Tenam was more influential than using the conventional approach (teacher centered) in improve student learning outcomes. Based on the paired samples statistics test that has been carried out, a significance value of 0.000 (<0.05) is obtained, and the t-test with independent sample t test tcount > ttable (2.240 > 1.686). This shows that Ha is accepted and H0 is rejected, and there are differences in the learning outcomes of the CPA approach compared to the teacher centered approach. From the results of this study it is suggested that teachers use the CPA approach in providing learning concepts mathematics. Educators are expected to be able to provide teaching using concrete objects so that mathematics feels closer to the child's world. This is expected to have a positive influence in improving learning outcomes.

The operation of non-reactor nuclear installations that use nuclear material in the process must be ensured safely during the process. One of the assessments of the safety level of the protection system that has been owned by the installation is using the Safety Integrity Level (SIL) which assesses the safety level of the protection system based on the value of the risk reduction factor that the protection system can achieve. The uranium evaporator and deposition vessel at the Experimental Fuel Element Installation (EFEI) is one of the installations that uses nuclear material in the process so it is necessary to assess the SIL of these 2 vessels. The piping and instrumentation diagram (P&ID) is used to determine the SIL value and Safety Instrumented System (SIS) component are installed in evaporator and deposition vessel. Maintenance data and OREDA (Offshore Reliability Data) are used to determine the failure rate. After knowing and determining the installed SIS components, then determining the architecture vote of the Safety Instrumented Function (SIF) based on the P&ID diagram, so that it can be known that the installed SIS uses vote 1oo1, 1oo2, 1oo3, or the appropriate vote. The installed SIF architecture vote will determine the equation used to calculate the Probability Failure on Demand (PFD). The total PFD obtained is adjusted to the SIL table to find out what SIL level the installed protection system is at. The value of the safety level of the protection system with SIL assessment in the evaporator vessel obtained 2 protection systems with SIL values of level 2 all and in the deposition vessel obtained 2 protection systems with SIL values of level 1 and level 2. The SIL value in the evaporator and deposition vessel analyzed has not reached level 3 or 4, so it is necessary to add SIF to the SIS protection system to increase the SIL value until the SIL value is obtained between level 3 or 4 because safety in the operation of non-reactor nuclear installations is absolute.Keywords: Non-Reactor Nuclear Installations, PFD, SIF, SIL, SIS

Background and purpose: Indonesia ranks the first highest mortality rate of COVID-19 in Southeast Asia with an average case fatality rate (CFR) of 2.7%. South Sumatra is ranked 14th out of 34 provinces in Indonesia, with a CFR value related to COVID-19 reaching 5.1%, per June 21, 2021. This study aims to determine the descriptive epidemiology of COVID-19 in Palembang City. Methods: This research used a descriptive epidemiology approach and spatial analysis with the geographic information system. Then the secondary data were collected from the Palembang City Surveillance Report from March 2020 to February 2021 with a total of 7,423 cases, as well as geographic data on the coordinates of health services for all hospitals and public health centers (PHCs) in Palembang City. Results: The data shows that the age group of 25 to 39 years old dominated the COVID-19 cases. The morbidity and mortality rates in men was higher than women, and much higher at the age of above 60 years old. The most dominant symptom in the deceased COVID-19 patients was shortness of breath and the comorbid history increased the risk of death for patients with COVID-19. The highest number of confirmed cases of COVID-19 was found in the sub-district with the highest population, including the PHC of Padang Selasa, Ilir Barat I (393 patients), while the lowest number of cases was reported in Karyajaya PHC, Kertapati (7 patients). Conclusion:This study highlights the need in preventing mature deaths of COVID-19 patients by prioritizing elderlies who suffered from comorbidities at the family level and health services to support the government programs.

The researcher conducted a survey using questionnaires to be filled out by the students, the IRE teachers, and the headmaster of SMP Kharisma Bangsa. The research sample consisted of 70 respondents involved through random sampling. The collected data were analyzed using regression analysis to test the research hypothesis. The results of the study showed that pedagogical competence and professional competence significantly influenced IRE learning outcomes at SMP Kharisma Bangsa. Teachers’ pedagogical competence and professional competence respectively were found to have a significant positive contribution to IRE learning outcomes, demonstrating the importance of their ability to plan and deliver lesson material effectively and the importance of their in-depth knowledge and understanding of IRE subjects. Based on these findings, SMP Kharisma Bangsa should pay greater attention to the development of pedagogical competence and professional competence of IRE teachers. Teachers should get further training and education to improve their skills in planning and delivering lessons in an effective manner. In addition, institutional support in increasing teachers’ knowledge and in-depth understanding of the subjects of IRE is also very important. These three items should be done to significantly improve the learning outcomes of IRE at SMP Kharisma Bangsa.
