Abstract

Multiple linear regression analysis has assumptions that must be met, one of which is multicollinearity. Multicollinearity occurs when the independent variables correlate with each other, resulting in the regression coefficient produced by multiple linear regression analysis being very weak or unable to provide analysis results that represent the nature or influence of the independent variable concerned. The detection of multicollinearity can be known through the VIF value. In this study, human development index data on Kalimantan Island in 2019 detected multicollinearity because some independent variables have a VIF value of more than 10 so that the method used to overcome multicollinearity in this study is Principal Component Analysis (PCA). Based on the results of research using the Principal Component Regression method, There are five independent variables that influence the IPM that is Percentage of Poor Population, Number of Health Workers, Number of Workforce, Number of High Schools, and Number of High School Teachers.

Abstract

AbstrakKesehatan gigi dan mulut merupakan aspek penting dalam mendukung kesejahteraan anak-anak serta mencegah penyakit gigi sejak dini. Namun, rendahnya kesadaran masyarakat terhadap kebersihan gigi menyebabkan tingginya prevalensi karies gigi pada anak-anak. Untuk mengatasi permasalahan ini, program sosialisasi dan edukasi kesehatan gigi dilaksanakan pada 26 Juli 2024 di SDN 001 Tabalar Muara sebagai bagian dari Kuliah Kerja Nyata (KKN) Universitas Mulawarman. Kegiatan ini bertujuan meningkatkan pemahaman siswa mengenai pentingnya menjaga kebersihan gigi serta mengajarkan teknik menyikat gigi yang benar melalui pendekatan interaktif, seperti pemaparan materi, praktik langsung, dan diskusi kelompok. Hasil kegiatan berdasarkan observasi menunjukkan peningkatan kesadaran siswa, meskipun masih ditemukan kebiasaan kurang baik, seperti konsumsi makanan manis berlebihan dan tidak menyikat gigi sebelum tidur. Sebagai tindak lanjut, poster edukatif disebarluaskan di lokasi strategis untuk memperkuat pesan yang disampaikan. Edukasi berkelanjutan serta dukungan dari berbagai pihak diharapkan dapat membentuk kebiasaan menjaga kesehatan gigi sejak dini dan menurunkan angka penyakit gigi pada anak-anak. Kata kunci: edukasi; gigi anak; kebersihan; kesehatan; sosialisasi AbstractOral health is an important aspect in supporting children's welfare and preventing dental disease from an early age. However, low public awareness of dental hygiene causes a high prevalence of tooth decay in children. To overcome this problem, a dental health socialization and education program was implemented on July 26, 2024 at SDN 001 Tabalar Muara as part of the Mulawarman University Community Service Program (KKN). This activity aims to increase students' understanding of the importance of maintaining dental hygiene and teach proper tooth brushing techniques through an interactive approach, such as material presentation, direct practice, and group discussions. The results of the activity based on observations showed an increase in student awareness, although there were still bad habits, such as excessive consumption of sweet foods and not brushing their teeth before going to bed. As a follow-up, educational posters were distributed in strategic locations to reinforce the message conveyed. Continuous education and support from various parties are expected to form the habit of maintaining dental health from an early age and reduce the number of dental diseases in children. Keywords: education; children's dental health; hygiene; health; socialization

Abstract

Somers'd correlation is a analysis of correlate is used for data with ordinal scale and formed in a contingency table. Somers'd correlation can be used for symmetric and asymmetric relationships. In this case, will be explained about Somers’d asymmetric correlation. Somers'd dYX correlation for asymmetrical association applied to data from questionnaires about their comfortable level of Students live in dorms of Melati formed into 2 contingency table, the contingency table for boarding facilities with the comfortable level of students and the quality of the food with the comfortable level of students. Based on the analysis of correlation Somers'd dYX, it can be seen that there is relationship between boarding facility with comfortable level of students and quality of food with comfortable level of students, and then correlation coefficient from 2 contingency table is 0,330 and 0,345 respectively
