Abstract

Clustering is a data processing in data mining, namely a clustering process by separating a set of data into smaller groups or clusters based on similar characteristics. A clustering method in data mining is K-Means. The KMeans method processes data into the desired number of clusters and the data will be placed into clusters based on the proximity of the centroid or distance to each cluster. The conventional K-Means method has the disadvantage, namely the initial centroid selection is random so it can produce different results. Therefore, initial centroid selection can improve accuracy in the clustering process. Determining the initial centroid can be done in various ways such as Rank Order Centroid (ROC). ROC is a method that gives a score to each criterion according to its ranking appropriate to score based on its priority level. This research compares the evaluation results with the Davies Bouldin Index (DBI) method, which is a cluster validation method for grouping methods. The results of the clustering method using wheat grain data show that a DBI KMeans value using ROC of 0.33350 with 4 iterations in 2 clusters. Keywords : Clustering, K-Means, centroid, ROC

Abstract

Abstract:  Digital promotion in early childhood education institutions is often conducted intuitively without data analysis and audience behavior insights, leading to suboptimal Instagram Ads performance. This issue was also identified at Al Ghazi Daycare. This community service program aimed to provide assistance in developing Instagram Ads strategies based on engagement analysis and parents’ psychological patterns to improve digital promotion effectiveness. A participatory training and mentoring approach was applied, including needs assessment, training on Instagram Insights and Meta Business Suite, content and posting schedule design, as well as ad implementation and evaluation. The results show improved managerial skills in handling data-driven Instagram Ads, accompanied by increased digital interaction and enrollment interest during the advertising period. This program demonstrates that combining engagement analytics with audience psychological insights can support effective and sustainable daycare promotion.Abstrak: Promosi digital pada lembaga pendidikan anak usia dini masih sering dilakukan secara intuitif tanpa analisis data dan pemahaman perilaku audiens, sehingga efektivitas Instagram Ads belum optimal.
