Social and economic welfare reflects the quality of life in a region and is influenced by local social, economic, and environmental factors. East Java, as the second most populous province in Indonesia, faces challenges in improving the welfare of its residents, particularly due to varying regional characteristics such as employment, education, and population demographics. To understand the patterns of interrelationships among factors affecting welfare, this study conducted a klaster analysis to group regions based on similar characteristics. The klaster analysis employed both hierarchical (complete linkage) and non-hierarchical (K-means) approaches to determine the optimal number of klasters. The results revealed that the level of diversity across regions in East Java tends to be homogeneous in social and economic aspects, with average values exceeding standard deviations. Assumption tests for the klaster analysis confirmed that the data met the assumptions of multivariate normal distribution and dependency.Through hierarchical (complete linkage) and non-hierarchical (K-means) klaster analysis, two main klasters were formed, dividing districts/cities in East Java based on welfare characteristics. Using the complete linkage method, 27 regions were grouped into klaster 1, and 11 regions into klaster 2, while K-means grouped 26 regions into klaster 1 and 12 regions into klaster 2. Out of the six variables used, one variable was found to be insignificant in influencing the klastering results. Based on the mapping results, the grouping aligns with similar criteria, where urban areas predominantly fall into one klaster, and the other klaster is dominated by rural areas.

The purpose of Community Service Activities is to provide Public Speaking skills to residents and cadets of Cupak Village in the form of socialization.

In addition, public speaking can also be used to promote tourism potentials that have not been known to the general public. The method used is to provide training through the provision of Public Speaking material to cupak villagers and then discuss together related to existing problems.

Penelitian ini bertujuan untuk menganalisis pengaruh manajemen Diklat Perilaku Hidup Bersih dan Sehat (PHBS) terhadap kesehatan santri putra di Pesantren Darunnajah 2 Cipining. Penelitian ini menggunakan pendekatan kuantitatif dengan metode analisis regresi sederhana, penelitian ini melibatkan 57 responden yang dipilih dengan teknik stratified random sampling dari total populasi 808 santri. Instrumen penelitian berupa kuesioner yang telah diuji validitasnya, untuk mengukur manajemen Diklat PHBS serta kondisi kesehatan fisik, mental, sosial, dan spiritual santri. Hasil penelitian menunjukkan adanya hubungan signifikan antara manajemen Diklat PHBS dan kesehatan santri, dengan persamaan regresi Y = 40.580 + 0.667X dan koefisien korelasi sederhana rxy = 0.573. Penelititan ini mengindikasikan bahwa 31,6% kesehatan santri dipengaruhi oleh implementasi Diklat PHBS, sementara 68,4% dipengaruhi oleh faktor lain. Implikasi dari penelitian ini adalah bahwa penerapan Diklat PHBS yang terstruktur dan sistematis dapat menjadi strategi penting dalam pembinaan kesehatan di pesantren, yang pada akhirnya mendukung proses pendidikan secara keseluruhan. Hal baru dari penelitian ini yaitu terletak pada penekanan pentingnya integrasi antara manajemen pendidikan Islam dan program kesehatan untuk menciptakan lingkungan belajar yang sehat, yang jarang dibahas dalam penelitian sebelumnya. Hasil ini dapat dijadikan referensi bagi pengelola pesantren dan peneliti selanjutnya dalam mengembangkan strategi kesehatan yang lebih komprehensif di lembaga pendidikan Islam.
