This study aims to analyze the correlation between students' academic achievements and the effectiveness of campus promotion in attracting new prospective students. Academic performance is often used as an indicator of educational quality in higher education and is frequently highlighted in promotional strategies. However, the direct relationship between student academic achievement and campus promotion success has not been fully understood. This research utilizes the Apriori method in data mining to discover hidden patterns related to student academic performance and campus promotion. The data analyzed include undergraduate students from the 2017–2019 cohorts at STMIK Kaputama Binjai, with variables such as study programs, GPA, school background, and major during high school. The results indicate a significant correlation between academic achievement and the effectiveness of campus promotion, which can be used by institutions to develop more targeted promotional strategies. By leveraging data mining, universities can more effectively identify potential student segments and enhance the overall image of the institution.

The Apriori method is one of the algorithms used in data mining to find association patterns, such as "association rules", in large data sets. This method was developed by Rakesh Agrawal and Ramakrishnan Srikant in 1994. The purpose is to test the correlation between facial skin problems and the type of product used by finding min support and min confidence using the apriori method.The results obtained based on this analysis are that there are 2 rules that meet the minimum requirements to form a combination of 2 itemsets with a minimum support value of 95% and a minimum confidence of 100%.
 

Infant and Young Children Feeding (IYCF) are possible efforts? used in prevention and reduction of stunting. Many children are deprived nutrition because food given too fast and inaccuracy responsive feeding. Level knowledge previous mother? No know wrong way to be the right way appropriate. The aim of the study was mother knowledge about infant and young children feeding. For measure level of mother knowledge about infant and young children feeding and responsive feeding in toddlers and stunted children? at the Public Health Center Sumbermanjing Kulon and Pagak in Malang Regency. Desain of this study used descriptive survey with a total of 60 respondents selected use total sampling technique. Data is collected through questionnaire that includes aspect knowledge mother, preparation and processing food, complementary feeding, and responsive feeding. Result of this study show that mother knowledge about infant and young children feeding in category good knowledge (67%), and less knowledge (33%). Based on every indicator from mother behavior show that preparation and processing food in category good (86%), complementary feeding in category good (100%), as well practice giving responsive feeding (80%). However, some mother is also lacking in responsive feeding (20%). Although level knowledge from Mother Enough high , related with knowledge mother who became source main that is support family too. This matter show necessity intervention that is not only focus on education and exposure but also on level I want to know, mother For increase knowledge Mother to giving eating in toddlers and children For in the future For prevent the occurrence of stunting.

Recording death certificates involves documenting various diseases or conditions that lead to a series of deaths, accidents, injuries, and death. RSUD dr. perinatal age, but also the quality of statistical reporting of perinatal infant deaths in hospitals. The aim of carrying out this research is to produce a special electronic-based perinatal death certificate form format at Dr. Soedomo Trenggalek Regional Hospital which can provide a more complete picture regarding the identity of the baby, the baby's mother, diagnosis and other items provided by the doctor in order to increase the accuracy of recording. death at perinatal age. This research method is a qualitative type using data collection techniques in the form of observation, interviews, documentation and brainstorming by exploring 3 variables in the form of physical aspects, anatomical aspects and content aspects. Based on the research results, it can be concluded that the design of the general death certificate at Dr. Soedomo Trenggalek still does not contain more detailed information regarding the baby's condition before death so that it can cause errors in determining UCOD (Underlying Cause of Death) according to ICD 10. Therefore, the preparation of this special perinatal death certificate has three main aspects, namely the physical aspect, the anatomy, and content aspects according to user filling needs. In its implementation, the design of this perinatal death form will be designed electronically so that the information contained in it will be integrated electronically through the hospital's SIMRS to support the transition period towards RME (Electronic Medical Records).

This study aims to determine the differences in student learning achievement between the control class and the experimental class, and to determine the effect of the Integrated Cooperative Script Al-Quran Learning Method on the Concept of the Reproductive System on the Learning Outcomes of Class XI Students of SMAS Al-Washliyah 3 Medan. The method used is an experiment whose implementation uses a quasi-experiment type with a nonequivalent control group design. The study population consisted of 48 students, namely class XI IPA-1 totaling 26 students and class XI IPA-2 totaling 22 students. Less than ideal results were observed for learning outcomes in the control class when the Cooperative Script Learning Method was not integrated with the Qur'an. An average of 78.6 describes the learning objectives. The Cooperative Script Learning Method Integrated with the Qur'an resulted in an increase in learning outcomes in the experimental class. The average (85.7), mode (87) and median (87), maximum value (97), and lowest value (75) all indicate learning outcomes. At a 5% error rate, the calculation of the independent sample t-test revealed that t table < t count (3.07 > 2.01). The experimental class had a higher percentage increase from pretest to posttest (85.15%) compared to the control class (77.98%). Therefore, the implementation of the Cooperative Script learning approach effectively contributed 55% of the total. Thus, it can be said that the learning outcomes of the experimental class that utilized the Integrated Cooperative Script Al-Quran Learning Method and the learning outcomes of the control class that used the Non-Integrated Cooperative Script Al-Quran Learning Method were significantly different.

Increasing population density and concretization in urban areas, such as Magelang City, have caused a significant decrease in green open spaces (RTH), which has an impact on food security and independence. Magelang City, with a population density of 7,361 people/km², faces a major challenge in providing adequate green spaces to support local food production. Rejowinangun Selatan Village, as one example, shows the limited green open spaces available. To overcome this problem, urban farming, especially through hydroponic techniques, offers an effective solution. The methods applied in this community service include various approaches to educate and directly involve the community in the practice of making hydroponics with solar panels. By utilizing renewable energy-based technology, such as solar panels and integrated electrical systems, hydroponic farming allows food production in limited spaces such as house terraces. This system not only increases food independence and security, but also ensures that the vegetables produced are healthier because of the minimal use of pesticides. Urban farming with the hydroponic method can optimize the use of limited space and become a productive and sustainable alternative for urban communities.
