Abstract

The achievement of human development can be reviewed from the Human Development Index (HDI), which is sourced from indicators of health, education, and state income. East Java Province is the second-most populous province in Indonesia which has a high work intensity in economic aspects and abundant natural and human resources. However, judging from the level of the human development index, East Java Province occupies the lowest position compared to other provinces on the island of Java. This study aims to identify significant factors affecting East Java's HDI using ordinal logistic regression. The data from Indonesia Statistics (Indonesian: Badan Pusat Statistik, BPS) of East Java province in 2020 includes seven variables, namely Gross Regional Domestic Product (GRDP), high school participation rate, infant mortality rate, health facilities, population density, labor force participation rate, and open unemployment rate. This study produced two ordinal logistic regression models in medium category HDI and high category HDI with a classification accuracy value of 97.37%. From this model obtained, a significant factor affecting the HDI of East Java is the participation rate of high school and health facilities.

Abstract

Breast cancer is one of the malignant tumors that begins in the breast cells that develop and attack the surrounding tissues; according to World Health Organization (WHO), breast cancer is globally declared the top five killer cancers. In Indonesia, breast cancer becomes the number one killer cancer.  One of the successes in breast cancer treatment is if the cure obtained by cancer patients can be proven to have the same life expectancy as those who do not have breast cancer.This study aims to know the probability of survival of breast cancer patients and know the factors that affect breast cancer patients' survival. The data were consist of 394 medical records of breast cancer patients at Dr. Soetomo Hospital Surabaya in the period January 2018 – December 2019, with variables used, i.e., initial age of infection, clinical stage, tumor size, metastatic to other organs, type of treatment, and patient status (life or death). This study using Kaplan Meier and Cox Proportional Hazard regression methods, and the result showed that the probability of survival of breast cancer patients (with data samples) was 0.737 or 73.7%. The variables that significantly affect breast cancer patients' survival are the initial age of infection, the clinic stage, and the tumor's size. This research provides information and motivation to the community related to life expectancy, especially in breast cancer patients, to stay motivated in the healing process. In addition, this research is also used to add insight to academics, especially the department of statistics, regarding the regression of Cox Proportional Hazard in analyzing the survival of breast cancer patients.

Abstract

Growth in the number of vehicles, especially in urban areas, has a significant impact on traffic density, especially during peak hours, so an approach is needed to group traffic conditions based on the volume of all types of vehicles and the degree of saturation using the K-Means Clustering algorithm. The data used are the volume of all types of vehicles and the degree of saturation obtained from the Surabaya City Transportation Agency. The clustering results show that there are 4 clusters of different traffic characteristics, such as the volume of 2-wheeled vehicles during heavy traffic conditions of more than 4700 vehicles with a degree of saturation of more than 0.45. Evaluation using the silhouette coefficient produces a value of 0.63, which means the quality of the cluster is in a medium structure. This study shows that the clustering method is effective in understanding traffic conditions, although additional features can be done to optimize the quality of the cluster.

Abstract

Prevalensi stunting di Kabupaten Ngawi, khususnya di Desa Soco, masih menjadi permasalahan kesehatan masyarakat yang memerlukan intervensi gizi berbasis pangan lokal yang tidak hanya bergizi tetapi juga memiliki daya terima tinggi pada anak. Salah satu kendala dalam program Pemberian Makanan Tambahan (PMT) adalah rendahnya penerimaan anak terhadap produk yang disediakan sehingga berdampak pada keberlanjutan konsumsi. Kegiatan pengabdian masyarakat ini bertujuan untuk mengevaluasi daya terima nugget ayam dan udang sebagai alternatif PMT berbasis pangan lokal yang dikembangkan sesuai preferensi anak dan kondisi masyarakat setempat. Metode yang digunakan adalah pendekatan kualitatif deskriptif melalui uji hedonik (organoleptik) terhadap lima parameter sensori, yaitu rasa, aroma, warna, tekstur, dan penampilan, dengan melibatkan delapan panelis yang terdiri dari anak stunting dan ibu pendamping. Hasil evaluasi menunjukkan bahwa sebagian besar panelis memberikan penilaian “suka” hingga “sangat suka” pada seluruh parameter, meskipun terdapat masukan terkait variasi aroma, warna, dan tekstur yang perlu disempurnakan. Temuan ini menunjukkan bahwa nugget ayam dan udang memiliki tingkat penerimaan yang baik serta berpotensi dikembangkan sebagai PMT yang terjangkau, mudah dibuat, dan kontekstual dengan kebutuhan masyarakat desa. Inovasi ini tidak hanya berkontribusi pada diversifikasi PMT lokal, tetapi juga mendukung pendekatan pengabdian partisipatif dalam upaya pencegahan stunting di tingkat komunitas.   The prevalence of stunting in Ngawi Regency, particularly in Soco Village, remains a public health concern that requires nutrition interventions based on local food resources that are not only nutritious but also highly acceptable to children. One of the main challenges in the Supplementary Feeding Program (PMT) is the low level of children’s acceptance of the provided foods, which affects the sustainability of consumption. This community service activity aimed to evaluate the acceptability of chicken and shrimp nuggets as an alternative locally based PMT developed in accordance with children’s preferences and the socio-cultural conditions of the local community. The study employed a descriptive qualitative approach through hedonic (organoleptic) testing of five sensory parameters—taste, aroma, color, texture, and appearance—involving eight panelists consisting of stunted children and their mothers. The evaluation results indicated that most panelists rated the product from “liked” to “highly liked” across all parameters, although some feedback related to aroma, color, and texture variations suggested areas for further improvement. These findings indicate that chicken and shrimp nuggets demonstrate good acceptability and have the potential to be developed as an affordable, easy-to-prepare PMT that is contextually aligned with the needs of rural communities. This innovation not only contributes to the diversification of local PMT products but also supports a participatory community service approach in efforts to prevent stunting at the community level
