Abstract

Local area monitoring of maternal and child health is crucial for assessing health service quality. In Desa Simpang Tiga, challenges include a manual and unintegrated maternal and child health documentation system and limited cadre competencies in anthropometric measurements, antenatal care data management, and analysis. This community-based empowerment program aimed to address these issues through community partnership empowerment. The program involved focus group discussions and scientific and technical training for Posyandu and PKK cadres. A Wilcoxon Test evaluated the program's effectiveness by comparing pre- and post-training cadre competencies. Results showed significant improvements: cadre competency in anthropometric measurements increased by 20.8% (from 53% to 73.8%) (p < 0.05). Competency in maternal and child health data management and analysis increased by 43.8% (from 33.5% to 77.3%) (p < 0.05). These findings demonstrate the program's success in enhancing cadre competencies in basic maternal and child health measurements and data management in Desa Simpang Tiga.

Abstract

AbstractUnemployment is one of the serious problems in Indonesia's economic development. This unemployment describes human resources that have not been utilized optimally, as a result of which people's productivity and income have not been maximized, this can also be one of the causes of poverty and other social problems. This study aims to find out the general picture of the open unemployment rate in the Kalimantan region, get the best model and factors that influence the open unemployment rate and illustrate it through thematic maps. The study began with testing assumptions and spatial effects then continued with testing global regression modeling and Geographically Weighted Regression. The weighting function used in this study is adaptive gaussian kernel. The variable that has a positive effect on the open unemployment rate in the Kalimantan region is population density. While the variable that negatively affects the open unemployment rate is the Labor Force Participation Rate. Keywords:   Open Unemployment Rate, Kalimantan Island, Spatial, GWR

Abstract

Banjarbakula Bus Rapid Transit (BRT) is an inner-city bus-based mass transit system that provides a sense of comfort, safety, speed in mobility, and low cost in serving the citizens of Banjarmasin City and Banjarbaru City. Based on data on the number of passengers on the Banjarbakula BRT for the period April 2020 - February 2023, public interest in using the Banjarbakula BRT as a mode of transportation is quite high. However, the limited units and operational schedules make the Banjarbakula BRT unable to fully meet the needs of the public. Forecasting the number of passengers of BRT Banjarbakula for the next 12 periods is one of the measures to prepare the infrastructure, quality and units of BRT Banjarbakula in order to facilitate the public and create a better transportation system. In the Banjarbakula BRT passenger data, there is an increase in the number of passengers at certain times such as during religious holidays and school holidays, so this increase in passenger numbers is thought to be due to the influence of the calendar variation effect. This research intends to forecast the number of passengers of BRT Banjarbakula using the best ARIMAX model with the effect of calendar variation. The results indicate that the ARIMAX (0, 1, 1) model is the best ARIMAX model to forecast the number of passengers of BRT Banjarbakula for the next 12 periods. The forecast results indicate an increase in the month where the Christmas celebration and also the memorial haul guru sekumpul, so that the variable Christmas celebration and memorial haul guru sekumpul significantly affect the number of passengers of BRT Banjarbakula.Keywords: Forecasting, BRT Banjarbakula, ARIMAX with calendar variation effects

Abstract

Classification is a data analysis process that can predict classes based on predefined characteristics. In the era of big data, classification can be performed using machine learning. The problem of machine learning in classification analysis is imbalance data which often affect model performance. SMOTE and ADASYN are oversampling techniques to solve this problem. This study aims to evaluate the effectiveness of SMOTE and ADASYN in improving the performance of the Random Forest model on imbalanced data in the case of company bankruptcy using financial ratios. Models were built using training data with various splitting data and oversampling techniques. Then, the resulting models will be tested using testing data. The results show that the best model was achieved with a combination of splitting data 70:30 using SMOTE technique, which produced the highest f1-score of 40.57%, compared to ADASYN technique with 36.11% (a decrease of 4.46%), and without oversampling techniques with 19.51% (a decrease of 21.06%). The findings indicate SMOTE and ADASYN can identify minority values which are the main problem of imbalance data, with SMOTE showing better performance compared to ADASYN.

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.
