This research identified the best imputation technique for the price of gold in Turkey, Saudi Arabia, and Indonesia which has been applied to the GSTAR model based on the smallest RMSE value. The moving average smoothing technique with k = 2, 3, 4, and 5 have been used in this study. However, the moving average smoothing technique with k = 3 is the best technique for importing gold price data during weekends in Turkey, Saudi Arabia, and Indonesia.

Tourism activities are a necessity for individuals and communities because they provide a refreshing impact, both physically and spiritually. One tourism activity that can bring humans closer to nature and the Creator is ecotourism or ecological tourism. This study aims to analyze the factors influencing public perceptions and preferences in Jambi Province towards Ecological Tourism during the Covid-19 Pandemic, spanning the initial pandemic period, PSBB, PPKM, New Normal, and post-pandemic. This research method uses a quantitative approach with primary data from a survey in the form of questionnaires distributed to the community, which data analysis uses SEM-PLS assisted by Smart-PLS software. The results of this study suggest that based on the SEM-PLS path diagram, the path coefficients indicate that all aspects of visitor assessments of ecological tourism destinations in Jambi Province need to be improved, especially related to tourist destination cleanliness, ecological tourism accessibility, tourist attractions, and infrastructure conditions. Therefore, good cooperation between the community and the government is highly recommended in the management of ecological tourism areas in Jambi Province.

Penelitian ini menganalisis determinan kepemilikan akun keuangan formal di Indonesia pasca-pandemi menggunakan regresi logistik biner pada data Global Findex 2024 (N = 1.067). Variabel independen mencakup usia, pendidikan, pendapatan (quintile), gender, domisili, dan status ketenagakerjaan. Hasil menunjukkan pendidikan tinggi meningkatkan odds kepemilikan sebesar 412% (OR = 5,12; 95% CI = 2,18–14,10; p < 0,001), diikuti pendidikan menengah (OR = 2,43) dan quintile terkaya (OR = 2,22). Gender gap signifikan: perempuan memiliki odds 25% lebih rendah (OR = 0,750; p = 0,042). Status pengangguran menurunkan odds hingga 51% (OR = 0,487). Domisili pedesaan tidak signifikan (p = 0,624), menandakan konvergensi urban-rural akibat digitalisasi. Model valid (VIF < 1,3; Hosmer-Lemeshow p = 0,653; AUC = 0,716). Penelitian ini merekomendasikan intervensi berbasis odds ratio bagi OJK untuk mencapai inklusi 90% pada 2029.

One of the primary data that can be used in research is village potential statistics (PODES). The data was obtained based on research in a certain period by the Statistics Indonesia (BPS). This study aims to visualize the percentage of schools in each city/district in Jambi Province using R programming based on PODES data in 2014 and 2019. In this study, we not only visualize but also how to build attractive graphics and arrange them starting from windows, graphic size, dimensions, color, horizontal axis, vertical axis, and others. Of course, the graph produced in this study is different from the basic plot found in the R program, although the process carried out is also more complicated. From 2014 to 2019, in general, within a period of 5 years there has been an increase in the number of schools in each city/district in Jambi Province. However, from the university level, the number decreased. In 2014 the number of universities in Jambi City was 32 but in 2019 the number decreased to 24. There are even interesting things in Kerinci and Tebo district. In 2014 there were no universities listed, while in 2019 there were 3. This also affects the percentage of education level in each city/district.

The probit model is commonly used to study categorical response data. However, failing to account for spatial autocorrelation factors between regions can lead to inconsistent and biased parameter estimation results. This study focuses on examining the parameter estimation of the Spatial Autoregressive (SAR) Probit model through the Maximum Likelihood Estimation (MLE) method using the Fisher Scoring numerical iteration scheme. The model was implemented on poverty data across 131 regencies/cities in the Sumatra region for 2022. Empirical findings indicate that the GRDP growth rate, open unemployment rate, per capita expenditure, and expected years of schooling significantly affect the poverty rate. The results of this model development provide a prediction accuracy of 83.97%. This achievement is superior to that of the RIS Simulator technique, which only yields an accuracy of 74.05%. These results emphasize the advantages of the efficiency and accuracy of the Fisher Scoring approach in representing spatial dependencies in the poverty phenomenon in Sumatra.

Test of English as a Foreign Language atau sering dikenal dengan istilah TOEFL adalah salah satu bentuk tes untuk mengetahui kemampuan Bahasa Inggris seseorang. Tes tersebut mengidentifikasi beberapa kemampuan diantaranya listening, structure, witten expression, reading, dll. Model regresi dapat diterapkan pada prediksi TOEFL prediction test. Skor listening dapat diprediksi dari banyaknya soal listening yang benar dikali 0,74 kemudian ditambahan 31,41. Selanjutnya untuk skor structure and written expression dapat diprediksi dari banyaknya soal structure and written expression yang benar dikali 0,93 yang kemudian ditambahkan 31,24. Setelah itu skor reading dapat diprediksi dari banyaknya skor reading yang benar dikali 0,72 kemudian ditambahkan 31,40. Total prediksi skor TOEFL prediction test adalah hasil penjumlahan skor listening, structure and written expression, dan reading. Skor tersebut kemudian dikali 10 lalu dibagi 3. Sehingga total skor TOEFL prediction test berada antara 310-677.
