Penelitian ini merupakan penelitian ex-post facto, yang dilaksanakan di 8 SMK Negeri di Kota Yogyakarta. Teknik pengambilan sampel dengan proportionale random sampling. Sampel yang digunakan sebanyak 200 sampel. Teknik analisis data yang digunakan adalah Structural Equation Modelling (SEM) dengan pendekatan analisis faktor konfirmatori (Confirmatory Factor Analisys, CFA). Hasil penelitian menunjukkan bahwa: (1) Model konstruk peran kepala sekolah memiliki 2 dimensi, yaitu dimensi kepemimpinan dan dimensi manajerial. Kepemimpinan mempunyai 5 indikator, yaitu (a) kecakapan pribadi, (b) kecakapan relasional, (c) kecakapan profesional, (d) kecakapan berorganisasi, dan (e) kecakapan wirausaha. Manajerial mempunyai 4 indikator, yaitu (a) perencanaan, (b) pengorganisasian, (c) penggerakan, dan (d) pengendalian; (2) Kondisi riil peran kepala sekolah hampir sesuai dengan kondisi idealnya, ditunjukkan dengan mean kondisi riil yang sedikit lebih rendah dari mean kondisi ideal. Secara rinci kondisi riil peran kepala sekolah berdasar persepsi guru menunjukkan bahwa 28,36% guru memberikan nilai sangat tinggi, 59,20% guru memberikan nilai tinggi, 11,44% memberikan nilai sedang, 1,00% memberikan nilai rendah, dan 0% memberikan nilai sangat rendah. THE ROLE OF PRINCIPALS OF VOCATIONAL HIGH SCHOOLS IN YOGYAKARTA BASED ON TEACHER'S PERCEPTIONSAbstractThis study aimed to determine: (1) a construct model of the role of ideal principal in the vocational high school, which includes the dimensions and indicators of the role of the principal of vocational and (2) the real condition of the role of the principal of vocational schools in the city of Yogyakarta. This study was an ex-post facto implemented in 8 vocational high schools in the city of Yogyakarta. The population of this study was 983 teachers from 8 vocational schools. The sampling technique used was proportional random sampling. The samples were then distributed to 200 samples. The data analysis technique used was Structural Equation Modeling (SEM) with confirmatory factor analysis approach (Confirmatory Factor Analisys, CFA). The results of this research show that: (1) the construct model of the principal's role has two dimensions, the leadership dimensions and managerial dimensions. The leadership has 5 indicators, namely (a) the personal capabilities, (b) relational capabilities, (c) professional capabilities, (d) organizational capabilities, and (e) the entrepreneur capabilities. The managerial has four indicators, namely (a) planning, (b) organizing, (c) actuating, and (d) controlling; (2) the real condition of the role of the principal is almost the same as the ideal conditions. It is indicated by the mean of real conditions which is a little bit lower than the mean of ideal conditions. In details, the real condition of the principal's role based on the perception of teachers shows that 28.36% of teachers give very high value, 59.20% of teachers give high value, 11.44% of them give moderate value, 1.00% give a low value and 0% of them give a very low value.

Abstract

Kualitas kesehatan maternal di suatu negara umumnya diukur melalui indikator utama berupa Angka Kematian Ibu (AKI). Penelitian ini menganalisis pengaruh tiga faktor penting terhadap AKI di Indonesia, yaitu persentase perempuan usia 15–49 tahun yang pernah menikah dan memiliki anak hidup, persentase rumah tangga dengan akses sanitasi layak, serta rata-rata lama sekolah. Untuk mengidentifikasi pola hubungan nonlinier antara variabel-variabel tersebut yang tidak dapat dijelaskan secara optimal oleh model regresi parametrik, digunakan pendekatan regresi nonparametrik Spline Truncated. Model ini mampu menangani data dengan pola acak. Hasil estimasi menunjukkan bahwa model terbaik diperoleh dengan nilai Generalized Cross Validation (GCV) minimum sebesar 1,023 dan koefisien determinasi (R²) sebesar 0,9012. Temuan ini mengindikasikan bahwa ketiga variabel prediktor berpengaruh signifikan terhadap AKI dengan bentuk hubungan yang tidak sepenuhnya linier. Hasil penelitian diharapkan dapat menjadi dasar dalam perumusan kebijakan kesehatan yang lebih efektif dan berbasis data untuk menekan angka kematian ibu di Indonesia

Abstract

Learning basic graphic design materials at SMK Negeri 1 Godean is carried out with less conducive classroom conditions because the media used in learning is not appropriate so that students are not motivated to learn and there are some abstract materials that are difficult for students to understand. This research aims to design a learning media for basic graphic design materials using augmented reality technology. The method used in this research is the development method or research and development with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The tools used in this research are Corel Draw X7, Blender 3D, Unity, Vuforia, and Visual Studio Code. The data analysis technique used in this research is quantitative descriptive analysis technique. This research produces a learning media for graphic design materials using augmented reality technology applied to SMK Negeri 1 Godean with the results of feasibility testing, namely the media expert test obtained a score of 92% which was classified in the very feasible category, the material expert test obtained a score of 80% which was classified as feasible, and the small group test obtained a score of 81.52% which was classified as very feasible. The effectiveness test obtained an N-Gain value of 0.8005 with a high category, the percentage value of increasing learning outcomes obtained a value of 80% with a moderate category, and the effectiveness value obtained a value of 80 with an effective category. Thus, it can be concluded that learning media for basic graphic design materials using augmented reality technology is feasible and effective for use in learning so that learning basic graphic design materials at SMK Negeri 1 Godean runs more effectively and can improve student learning outcomes.

Abstract

The tourism sector is one of the main drivers of the national economy, which experienced a significant decline due to the COVID-19 pandemic. In the post-pandemic era, the recovery of international tourist arrivals shows a positive trend, thus requiring accurate forecasting methods to support tourism policy planning. ARIMA method are less effective in handling nonlinear and fluctuating data. This study applies the Fuzzy Time Series (FTS) approach, specifically the Chen and Singh models, which are capable of managing data uncertainty and representing linguistic patterns adaptively. The purpose of this study is to compare the accuracy of both models using two interval determination approaches, namely the Sturges method and the mean-based method, in forecasting international tourist arrivals through Sultan Hasanuddin International Airport during the period from January 2023 to September 2025. The analytical steps include defining the universe of discourse, performing fuzzification, constructing fuzzy logical relationships (FLR) and fuzzy logical relationship groups (FLRG), and applying defuzzification to obtain forecasted values. The forecasting accuracy was evaluated using the Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). The results show that the choice of interval determination method significantly affects forecasting performance, with the mean-based method producing more detailed and accurate intervals. Based on the evaluation, the FTS Singh model demonstrated the best performance, with MAPE of 2.16% and RMSE of 31.05, outperforming the Chen model under both interval approaches. Therefore, the combination of the FTS Singh model with the mean-based interval method is recommended as the optimal approach for forecasting post-pandemic international tourist arrivals, as it can capture fluctuating data patterns more precisely and consistently.
