Abstract

Internet usage in Indonesia has seen a significant increase, reaching 215.63 million users in 2022-2023, or 78.19% of the population. With the ease of internet access, digital news portals like Narasi TV have become a primary source of information for many people. However, the large number of news articles makes manual categorizing challenging. This study aims to classify Indonesian-language news documents from Narasi TV using the Nazief-Adriani algorithm for stemming and the K-Nearest Neighbor (KNN) method for classification. The text mining process begins with preprocessing, which includes case folding, tokenizing, stop-word filtering, and stemming. Using a dataset of 500 news documents, the study demonstrated that with a 90:10 data split, the average accuracy reached 93%, with the highest value being 100%. For the 80:20 data split, the average accuracy was 89%, with the highest value being 93%, and for a 70:30 data split, the average accuracy was 87%, with the highest value being 89%. In conclusion, the combination of the Nazief-Adriani algorithm and the KNN method with optimal k selection and random states obtained high accuracy, obtaining an average accuracy of 93%) in classifying Indonesian-language news documents. These results demonstrate the significant potential of text mining and classification techniques to manage digital news.

Abstract

Improving caregiver literacy regarding early childhood development is a strategic step to ensure optimal child growth and development. This educational activity was conducted at the Mawar Integrated Health Post (Posyandu Mawar), Tampingan Village, Boja District, involving 20 caregivers as active participants. The series of activities were systematically arranged, including a pre-test to determine the level of initial understanding, counseling through a lecture method accompanied by comprehensive material delivery, interactive discussions that allowed participants to exchange experiences, practice of child development stimulation as a form of direct skills, and a post-test to assess improvements in learning outcomes. The analysis results showed that the educational activity had a significant impact on improving caregiver literacy. The average pre-test score of 53.25 (SD = 9.54) increased to 69.60 (SD = 10.30) in the post-test. The average difference of 16.35 (SD = 5.84) with a 95% confidence interval between 13.62–19.08 indicated a significant increase. The paired t-test yielded a value of t(19) = 12.515 with p < 0.05, confirming a significant difference between the scores before and after the program. The percentage increase of 30.7% indicates the effectiveness of the applied educational method. The recommendation from this activity is the need to develop an educational program that is carried out in a sustainable and structured manner, accompanied by mentoring involving health workers, PAUD educators, and support from the village government, so that caregiver literacy can continue to increase and optimal child growth and development can be guaranteed from an early age.
