Abstract

Population data is an important piece of information that is useful for regional planning and development. Insight into the state of an area is more straightforward to observe if there are grouped sub-districts. In this case, data mining techniques can identify patterns and relationships in population data. The K-Means algorithm is a clustering technique that divides data into groups or clusters based on similar characteristics. This research aims to apply the K-Means method with various approaches to clustering sub-districts in the Bojonegoro district according to population data. The research method used is a quantitative method with an exploratory study in the application of the K-Means method with a variety of approaches, namely the use of the Kernel K-Means method by utilizing the mapping function to map data to a higher dimension before the clustering process. In addition, the Fast K-Means method is used, which reduces the model training time to improve the cluster-centered recalibration problem as the amount of data increases. The data source used in this research is secondary population data in the form of birth, death, migrant, and moving variables obtained from the Satu Data Bojonegoro website developed by the Bojonegoro Regency Government. It is found that the best K-Means approach is the Kernel K-Means method with a number of clusters of 5. The performance of the cluster method is evaluated by measuring the average distance within the cluster. The data coordinate pattern in the Kernel K-means method clustering shows a smooth initial trend when the value of the number of clusters is 5 so that the clusters formed are obtained clearly. The conclusion from this study's results is that the K-Means method's best approach in grouping sub-districts in Bojonegoro district is the Kernel K-Means approach.

Abstract

According to a report by the Central Statistics Agency, the percentage of poor people in urban areas in September 2019 was 6.89%. Meanwhile, the percentage of poor people in rural areas in September 2019 was 13.10%. The data above is only a national percentage, there are still many provinces that have a poverty percentage above the national percentage, especially in Central Kalimantan Province. There are many factors that influence poverty, including education, employment status, working sector, and per capita income. This paper focuses on a study to determine the factors that have the greatest influence on poverty in Central Kalimantan Province in 2019. The results of this study simplify the poverty factor into 2 (two) factors, namely the first factor consisting of variables of education, work status, and sector. work. Meanwhile, the second factor consists of the variable per capita income for food. In addition, the greatest eigen value was obtained in the education variable of 465.67, which indicates that the education variable has the greatest influence on poverty in Central Kalimantan Province in 2019.

Abstract

This community service program has addressed data management challenges faced by Posyandu health workers in Pekapuran Raya Sub District, Banjarmasin City. The primary objective is to enhance digital data management capabilities among healthcare workers' through scientific and technical training using Microsoft Excel. The training was conducted at the Central Bureau of Statistics in Banjarmasin on September 3, 2024. Based on the collected data analysis from pre-test and post-test showed improvements in the three core competencies: data management ability (from 57.7% to 84.6%), data presentation capability (from 57.7% to 92.3%), and dashboard development skills (from 61.5% to 80.8%). Statistical analysis using the Wilcoxon test confirmed the significance of these improvements (p < 0.05). Furthermore, participants’ evaluation data analysis indicated that this program was highly effective, with 88.5% of participants reporting positive feedback on the training methodology, materials, and facilities. This intervention has effectively demonstrated the capacity of structured technology training to enhance community healthcare data management systems, especially for monitoring maternal and child health.

Abstract

Generation Z (Gen Z) is a generation that grew up in the digital era with intensive use of social media, including Instagram. As the largest user group, Gen Z consumes a wide range of influencer-generated content, including motivational content that may affect psychological well-being, particularly self-esteem. However, empirical studies specifically examining the influence of motivational content from Instagram influencers on Gen Z’s self-esteem remain limited. This study aims to analyze Gen Z’s interest in motivational content on Instagram and to examine changes in self-esteem before and after exposure to such content. A quantitative approach using a quasi-experimental one-group pretest–posttest design was employed. The sample consisted of 150 university students in Banjarbaru City selected through purposive sampling. Data were collected using the Rosenberg Self-Esteem Scale (RSES) administered via questionnaires. The Wilcoxon Signed-Rank Test was used to analyze differences in self-esteem scores before and after treatment. The results indicate a significant increase in self-esteem following exposure to motivational content on Instagram. The average post-treatment self-esteem score was higher than the pre-treatment score, confirming the positive impact of motivational content. In addition, although most respondents reported only occasional exposure to motivational content, the majority expressed liking and interest in such content. These findings suggest that motivational content on Instagram contributes positively to enhancing Gen Z’s self-esteem and may serve as an effective medium for psychological empowerment.

Abstract

Indeks Kualitas Lingkungan Hidup (IKLH) merupakan indikator yang dapat memberikan gambaran tentang kualitas lingkungan hidup di suatu wilayah. IKLH digunakan sebagai alat evaluasi dalam berbagai program perbaikan kualitas lingkungan hidup dan sumber informasi untuk mendukung pengambilan kebijakan mengenai perlindungan dan pengelolaan lingkungan hidup. Dalam perhitungan IKLH terdapat empat indikator, yaitu Indeks Kualitas Air (IKA), Indeks Kualitas Udara (IKU), Indeks Kualitas Lahan (IKTL), dan Indeks Kualitas Air Laut (IKAL). Penelitian ini bertujuan untuk menganalisis pengaruh persentase jumlah penduduk, Produk Domestik Regional Bruto (PDRB), dan jumlah kendaraan bermotor terhadap IKLH di Provinsi Kalimantan Selatan tahun 2022. Metode penelitian yang digunakan dalam penelitian ini adalah analisis regresi spasial berbasis area. Data yang digunakan merupakan data sekunder tahun 2022 dari Badan Pusat Statistik (BPS) dan Dinas Lingkungan Hidup (DLH) Provinsi Kalimantan Selatan, meliputi 13 kabupaten/kota sebagai area pengamatan. Hasil penelitian menunjukkan bahwa model Spatial Autoregressive Moving Average (SARMA) merupakan model terbaik untuk memodelkan faktor-faktor yang diduga berpengaruh terhadap IKLH. Dari model SARMA diperoleh bahwa persentase jumlah penduduk, PDRB dan jumlah kendaraan bermotor berpengaruh signifikan terhadap IKLH di Provinsi Kalimantan Selatan. Koefisien determinasi sebesar 80,65% menunjukkan bahwa model mampu menjelaskan keragaman IKLH secara kuat. Kebaruan penelitian ini terletak pada penggunaan model SARMA yang mampu menangkap pengaruh spasial lag dan eror secara simultan, serta temuan hubungan positif PDRB terhadap IKLH yang mengindikasikan bahwa pertumbuhan ekonomi di Kalimantan Selatan dapat berjalan seiring dengan peningkatan kualitas lingkungan.
