Abstract: SMAN 1 Waru is experiencing rapid development, particularly in this digital era, with its students achieving notable success in sports, science, and arts. However, despite these achievements, the management of such accomplishments… plishments remains inadequate, rely-ing on manual systems. Consequently, the collection and recording of student achieve-ment data at SMAN 1 Waru are disorganized and often not up to date. Recognizing this issue, the community service team has developed an information system to manage stu-dent achievement data. This system includes comprehensive training to facilitate the ef-ficient processing of student achievements for both internal and external purposes, such as accreditation. The training session took place on March 28, 2024, at SMAN 1 Waru's computer laboratory and was attended by 35 students, website administrators, and three teachers. The training employed various methods, including lectures, practical exercises, and discussions. All participants demonstrated a clear understanding of the application's usage, as evidenced by their improved pre-test and post-test scores. Statistical analysis using the t-test confirmed the significance of this improvement, indicating that the train-ing effectively enhanced participants' understanding of using the student achievement website. Furthermore, the success of the training is reflected in the records of achieve-ment data inputted by the participants.             Keywords: achievement data; information system; website.

Abstract: Public awareness and ability to read food labels is still very low. A National Consumer Protection Agency survey stated that 6.7% of people in Indonesia pay attention to the completeness of food labels. One of the Messages… es of Balanced Nutrition is reading food labels. S1 Nutrition Study Program STIK Sint Carolus together with Nutritionists from the Galur Supporting Community Health Center provided counseling to mothers of toddlers on the topic "Let's Check the Coins (Composition and Nutritional Value Information) on Food Packaging" to 20 mothers of toddlers who visited the Posyandu. Counseling participants are given an identity and pretest form to fill out. The first session included material on definitions and food labels, and the second session provided material on how to read composition and nutritional value information. The third session involved practicing reading packaged food and conducting questions and answers and filling in the posttest form. After 3 days of providing material, monitoring and evaluation was carried out via Whatsapp. Based on the results of statistical analysis, 55% of mothers were classified as lacking knowledge during the pretest. However, it increased after nutrition education was carried out to 95% of mothers who were classified as well informed. The results of the Wilcoxon analysis show that there is a difference in knowledge between before and after counseling with p-value = 0.007. The results of monitoring and evaluation from 5 mothers, 100% of mothers had paid attention to food labels on packaging, especially composition and nutritional information. There has been a change in practice in reading food labels. Keywords: food labels; knowledge; nutrition information; nutrition counseling

Ulum, Muhammad Bahrul, Syaputri, Ayu Geby Gisela
Abstract: Abstract: Statistics and research are two things that cannot be separated. Although there are types of research that do not require the dominant role of statistics (qualitative research), but to be able to produce conclusions… sions that can be generalized to a wider population, statistics is needed. Such research is quantitative research with a positivistic paradigm, ie a phenomenon is real if it can be seen, measured, and classified. The application of statistical science which is generally needed by students in writing research such as theses and theses, will have a positive impact, especially in improving the quality of the research. To achieve this goal, it is necessary to conduct socialization to students. The socialization was carried out to several students from both state universities and private universities in the city of Palembang. The socialization was done by introducing and giving tutorials on how to use statistical applications such as SPSS and Eviews, because several lecturers at several universities in Palembang complained about the poor quality of research and some said that their students did not really understand how to use SPSS and Eviews. The first result of this service is that students' understanding of SPSS and Eviews can be seen from discussions and questions and answers, second, namely the ability of students to apply the use of SPSS and Eviews in research. Keywords: research; socialization; statistics Abstrak: Statistik dan penelitian merupakan dua hal yang tidak bisa dipisahkan. Meskipun ada jenis penelitian yang tidak membutuhkan peranan statistika yang dominan (penelitian kualitatif), namun untuk dapat menghasilkan kesimpulan yang dapat digeneralisasikan ke populasi yang lebih luas diperlukan ilmu statistika. Penelitian yang demikian adalah penelitian kuantitatif dengan paradigma yang positivistik, yakni suatu gejala itu adalah nyata jika bisa dilihat, diukur, dan diklasifikasikan. Penerapan ilmu statistik yang umumnya dibutuhkan mahasiswa dalam penulisan penelitian seperti skripsi dan tesis, akan berdampak positif terutama dalam meningkatan kualitas penelitian tersebut. Untuk mencapai tujuan tersebut maka perlu diadakan sosialisasi kepada mahasiswa. Sosialisasi dilakukan pada beberapa mahasiswa baik dari perguruan tinggi negeri maupun perguruan tinggi swasta di Kota Palembang. Sosialisasi dilakukan dengan cara mengenalkan dan memberikan tutorial bagaimana penggunaan aplikasi statistic seperti, SPSS dan Eviews, karena beberapa dosen di beberapa universitas di Palembang mengeluhkan buruknya kualitas penelitian dan ada juga yang mengatakan bahwa mahasiswa mereka tidak begitu mengerti cara penggunaan SPSS dan Eviews. Hasil dari pengabdian ini yang pertama adalah pemahaman mahasiswa mengenai SPSS dan Eviews dapat dilihat dari diskusi dan tanya jawab, kedua yaitu kemampuan mahasiswa dalam menerapkan penggunaan SPSS dan Eviews dalam penelitian.

ANALYSING STUDENT MENTAL HEALTH THROUGH K-MEANS CLUSTERING AND MULTI-STAGE SAMPLING METHODS

Rahmat Hidayat, Dede Pratama
Abstract: Abstract: Mental health is an essential aspect of overall well-being, particularly for university students vulnerable to emotional strain. This study aims to identify clusters of student mental health trends using the K-Means&#8230; Means clustering technique. The research involved 60 students from four academic programs at the Faculty of Science and Technology, selected using stratified and cluster sampling techniques. Data were collected using a modified Mental Health Inventory (MHI). The results revealed distinct commonalities among majors: the Statistics program was predominantly defined by the depressed cluster at 53.3%, while Mathematics followed at 40% within the same cluster. In contrast, Biology students predominantly fell under the neu-tral/stable cluster (66.7%), whilst Information Systems students exhibited an even distribution (33.3% per cluster) without a dominant trend. The clustering quality was evaluated using the Silhouette Coefficient, yielding a range of 0.39 to 0.60. Biology (0.60) and Statistics (0.54) exhibited a reasonable structure, but Information Systems (0.39) and Mathematics (0.34) demonstrated a deficient structure. In conclusion, K-Means effectively discerns mental health patterns, providing a data-driven basis for targeted psychological interventions in educational settings.

Zulkarnain, Iskandar, Sri Wahyuni, Meri, Sonata, Fifin
Abstract: Abstract: Hospitals play an important role in examining the scan results of patient data infected with the Covid 19 virus. However, there are problems when processing the scan results, namely that sometimes errors occur&#8230; in the scan data, causing many failures and delays in sending data to the Health Office. The purpose of this study is to build a Desktop-based decision support system application that can facilitate hospitals in selecting the eligibility of the scan results of Covid 19 patient data. The urgency in examining the scan results of Corona patient data is a very pressing public health issue, because the long-term impact is very significant for patients. Thus, a scientific discipline is needed that can support the decision-making process, namely the Decision Support System using the Preference Selection Index (PSI) method. PSI is a simple and easy calculation method, based on statistical concepts without having to determine attribute weights. The results of this method are clear and firm values ​​​​based on the level of strength of the rules applied. The results of the research conducted on the PSI process can be concluded that valid Covid 19 patient data is Recap File I with a value of 0.2042 which is declared valid and accepted.             Keywords: covid-19; decision support system; PSI
