Abstract

The Population-Oriented Development Index (IPBK) is an important indicator for measuring regional development success, focusing on human resource quality. This study aims to project the IPBK for 2024–2026 and identify the best method for projecting the IPBK in Gorontalo Regency. The projection methods used are single and double exponential smoothing. The IPBK data for Gorontalo Regency was obtained from the 2024 BKKBN Central Publication. The variables include participation (X1), sustainability (X2), inclusiveness (X3), holistic integration (X4), equality (X5), and IPBK (X6). The data was analyzed using Minitab 16 software. The results indicate that the double exponential smoothing method outperforms the single exponential smoothing method for projecting the IPBK and its dimensions in Gorontalo Regency, achieving a MAPE value of less than 10\%. The IPBK projections and its dimensions for 2024–2026 using the double exponential smoothing method show an annual upward trend, predicting that by 2025–2026, Gorontalo Regency's IPBK status will rise from category 3 (upper-middle status) to category 4 (high status). This high status indicates that Gorontalo Regency has achieved significant progress in key indicators reflecting the welfare and quality of life of its residents.

Abstract

Research on complications of Diabetes Mellitus (DM) is multifactorial, where the risk factors causing DM complications are interrelated, leading to confounding bias, which results in inaccurate research findings. Confounding bias can be reduced using the propensity score method. This study aims to compare the performance of the Propensity Score Stratification (PSS) and Propensity Score Matching (PSM) methods with the Multivariate Adaptive Regression Spline (MARS) approach in estimating treatment effects on DM complication cases. The data used is the medical records of type-2 DM patients at Hospital X. The results showed that the PSS method with the MARS approach is not suitable for small data sets, as it can lead to treatment or control groups lacking members, making it impossible to calculate the p-value in balance testing or the Percent Bias Reduction (PBR). The estimated Average Treatment Effect (ATE) using the PSS method was 0.487 with a PBR of 35.1%, whereas the estimated Average Treatment for Treated (ATT) using the PSM method was 0.531 with a PBR of 99.46%. These PBR values indicate that the best method for estimating treatment effects and the one that can reduce the most bias in this case is the PSM method with MARS. The analysis also showed that serum uric acid levels significantly affect the peripheral diabetic neuropathy (PDN) status of DM patients.

Abstract

Cooking oil is one of the primary raw materials used in Indonesia. In this study, a comparison of the two forecasting models from the two methods, namely Neural Network and Grey System, was carried out. Forecasting is carried out on cooking oil raw materials, namely CPO production volume and demand for related products, namely biodiesel, to analyze changes in cooking oil prices. The appropriate forecasting model is expected to be able to describe the pattern of cooking oil price fluctuations for the following few periods. The criteria for selecting the best model use the minimum MAPE testing value. The results show that the Grey System method produces the best forecasting model for biodiesel demand data with a small amount of data, while for the CPO variable, which has a larger amount of data, the best model is obtained using the Neural Network model, with the MLP (3-3-1) architecture.

Abstract

Bone Bolango is one of the districts that has experienced many village and sub-district expansion processes. This expansion process changes the village's potential data. Village potential is the carrying capacity for developing villages in order to improve community welfare. In order to accelerate village development, it is necessary to group villages according to their characteristics so that development is more focused and on target. The aim of this research is to group villages based on indicators of village potential so that groups of villages that have the same characteristics can be obtained, as well as to find out the best method for grouping villages in Bone Bolango Regency. The research results show that the optimum cluster for grouping villages in Bone Bolango Regency based on village potential indicators is the cluster using the ward method because it provides the smallest Xie-Beni index value compared to the fuzzy c-means method. The optimum number of clusters is three clusters. Cluster 1 has high average characteristics consisting of 57 villages, cluster 2 has low average characteristics (except livestock production) consisting of 94 villages and cluster 3 has characteristics of large area and high food production consisting of 9 villages.

Abstract This study aims to determine the effect of the use of multisensory methods assisted by digital flash card media on the ability to write descriptive essays of fifth-grade students of SD 7 Limboto. The type of research used is quantitative with the One Group Pre-test Post-test Design experimental method. The population in this study were all fifth-grade students of SDN 7 Limboto, totaling 10 people. The results showed that the ability to write descriptive essays of fifth-grade students of SDN 7 Limboto in the initial test (Pretest) was below the Minimum Completion Criteria (KKM) of Indonesian Language, namely 75, with an average score of 57.80. This shows that students' initial ability in writing descriptive essays is still classified as low to moderate. After the application of the multisensory method assisted by digital flash card media, the final test score (Posttest) showed a significant increase with an average of 75.40, where 70% of students reached or exceeded the KKM. This increase was accompanied by a more even distribution of scores, which reflects improvements in students' writing skills. Based on the results of the Paired Sample t-Test, the value obtained | thitung | = | -2.850| = 2.850 ttable value = 2.262 and p 0.001 ( 0.05), so H₀ is rejected and H₁ is accepted. This proves that the multisensory method assisted by digital flash card media has a significant effect on improving the ability to write descriptive essays for fifth grade students of SDN 7 Limboto.Keywords: Multisensory Method, Assisted by Digital Flash Card Media, Descriptive Essay.Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan metode multisensorik barbantuan media flash card digital terhadap kemampuan menulis karangan deskripsi siswa kelas V SD 7 Limboto.
