Abstract

The regression curve for nonparametric regression is assumed to belong to some infinite-dimensional collection of functions, which allows great flexibility in the form of the curve. This research intends to compare the Gaussian Kernel and Quadratic Spline regressions in four infectious diseases in Indonesia by 2021. The data used is secondary data from the Central Bureau of Statistics and the Ministry of Health, Indonesia, and the sample consists of four infectious diseases in Indonesia by 2021 (Tuberculosis, Diarrhoeal, Pneumonia, and COVID-19). Considering the correlation value, it was found that the independent and dependent variables of the four infectious diseases are all highly correlated (r values are more than 0.7). Furthermore, the scatter plots for four infectious diseases do not follow a particular pattern; due to this, parametric regression cannot be used to analyze the data. Therefore, nonparametric regression was applied in this research . According to the analysis, the Gaussian Kernel is the best regression technique for modeling four infectious diseases in Indonesia by 2021, which its R2 values are 99.85% (Tuberculosis), 100% (Diarrhoeal), 99.91% (Pneumonia), and 99.99% (COVID-19).

Abstract

Consumptive Behaviour refers to individuals’ purchasing behaviour without considering long-term needs and financial conditions. This research presents the results of an analysis of the consumptive behaviour of Generation Z in Dungingi Sub-District, Gorontalo City, selected because it represents the second-largest Generation Z population in the city. The study used the Partial Least Square-Path Modeling (PLS-PM) method to measure factors influencing consumptive behaviour: financial literacy, fear of missing out (FOMO), and hedonistic lifestyle. The sampling technique used was purposive sampling, resulting in 378 respondents aged 17-27 years who are employed. The analysis results indicate that financial literacy and FOMO significantly influence consumptive behaviour, with FOMO being the most dominant factor. The resulting model has a value of 0,930, meaning that the three latent variables can explain 93,0% of the consumptive behaviour of Generation Z. This study is expected to provide useful insights for policymakers and related parties in adressing consumptive behaviour issues among Generation Z.

Abstract

Penelitian ini bertujuan untuk mengestimasi fungsi survival pasien penderita stroke di RSUD Aloei Saboe kota Gorontalo bulan Agustus sampai dengan Desember 2019 menggunakan metode life table dan Kaplan Meier. Hasil estimasi keduanya dibandingkan dengan estimasi terbaik adalah yang menghasilkan nilai standar error terkecil. Hasil penelitian menunjukkan probabilitas survival pasien menggunakan estimasi life table adalah sebesar 0,8591 dan Kaplan Meier sebesar 0,8628. Berdasarkan perbandingan nilai standar error, dapat disimpulkan bahwa pada awal waktu survival, estimasi life table dan Kaplan Meier sama baiknya untuk menganalisis survival pasien. Namun untuk waktu survival yang semakin besar, estimasi Kaplan Meier menghasilkan nilai standar error yang lebih kecil dibandingkan estimasi life table.

Abstract

One of the spatial regression analysis used is the spatial durbin model (SDM). This model can be applied to obtain the relationship between X and Y variables and their spatial effects. This research was continued by testing the local spatial autocorrelation, namely the local indicator of spatial autocorrelation (LISA) which aims to provide information on the pattern of spatial relationships of each observation area in Bone Bolango regency. Stunting cases in Gorontalo province, especially in Bone Bolango regency, are in a status that needs to be addressed immediately due to the prevalence rate in Bone Bolango regency in 2019 above 20% based on the WHO standard. The results showed that the factors that significantly affected stunting in 2019 in Bone Bolango regency were exclusive breastfeeding, the  proper sanitation and poverty. Meanwhile, based on the spatial effect, the factors that significantly affected stunting in 2019 in Bone Bolango regency were the percentage of exclusive breastfeeding, the percentage of LBW, the number of children with CBI and poverty. Based on result from the LISA, the observation areas of stunting cases showed that the percentage of exclusive breastfeeding, the number of children with CBI and povertu had a spatial autocorrelation or forming a grouping on the distribution of the stunting cases, the number of children with IDL and poverty, there are sub-districts that have spatial autocorrelation.

Abstract

Stunting is a condition where toddlers fail to grow due to chronic malnutrition in the first 1000 days of life (HPK). Therefore, stunting cases in Gorontalo Province, especially in Gorontalo Regency, are among the cases that need to be addressed as soon as possible. The data used is secondary data from each Puskesmas in Gorontalo Regency, to see the factors that have a significant effect on the incidence of stunting in Gorontalo Regency in urban and rural areas using the stratified binary logistic regression method. In this study, the independent variables used were Gender, Birth Weight, Birth Height, Toddler Age and Nutritional Status. The test results using the stratified binary logistic regression method show that for urban strata there are 3 significant variables, namely Birth Weight, Age of Toddlers and Nutritional Status, then for rural strata there are 2 significant variables, namely Age of Toddlers and Nutritional Status. Wald test results show that there are differences between urban and rural areas.

Abstract

Business activities are mostly dominated by the community through the frame of Creative Economy and Micro, Small, and Menengan Enterprises. The choice of this frame is because the concept is simple and affordable, especially for the lower middle class. Home industry products in the framework of MSMEs play a major role in economic growth and employment. Problems for the creative economy and MSMEs include a lack of knowledge about the establishment of MSMEs, no permits, no branding, and the most important problem is digital marketing strategies. This is also found in Pelehu Village, Bilato District, with small household industries (MSMEs) starting to be developed but not yet using a digital business system, the appearance side of both Labeling, Packaging, and marketing is still relatively traditional and does not have a business license. To improve the economic self-sufficiency of business actors in Pelehu Village, Bilato District, Gorontalo Regency, the Thematic KKN implementation team by involving lecturers and students conducted socialization and training for MSME actors, housewives, and MSME observers. The main objectives of this Thematic KKN program are to assist MSMEs related to business licensing to obtain a Business Identification Number (BIN) to be legally legal; foster business actors to design MSME products and digital marketing systems; and involve students in guiding and motivating MSME actors. With the hope that it can independently encourage the economy in the Pelehu village area, Bilato District, Gorontalo Regency.

Abstract

This study presents a systematic literature review on the integration of mathematics and COVID-19, focusing on how the pandemic has transformed educational practices into online learning and emphasized the importance of mathematical modeling in understanding and managing virus spread. Utilizing qualitative methodology, this research processes data from articles sourced from the Dimensions database, analyzed using VOSviewer for bibliometric mapping. The findings indicate a significant shift in teaching practices, with the rapid adoption of digital technologies facilitating online mathematics education. This transition not only highlights the flexibility of digital platforms but also the challenges in engaging students and effectively conveying complex mathematical concepts remotely. Additionally, the review reaffirms the critical role of mathematical modeling in predicting the pandemic's trajectory and informing public health strategies. The study also explores the broader implications of these shifts, suggesting that the integration of technology in mathematics education, triggered by the pandemic, may have long-lasting effects on pedagogical approaches. Challenges such as technology access inequality and the need for pedagogical adjustments to optimize online learning environments are discussed. This research contributes to the academic discourse by mapping the evolution of mathematical applications during a global health crisis and suggests directions for future research to enhance the resilience of educational systems against similar disruptions.
