Truncated spline nonparametric regression is a nonparametric regression analysis using a segmented polynomial model. This segmented nature provides flexibility so that the regression model can adapt more effectively to the local characteristics of the data. The purpose of this study was to obtain a regression model and determine the factors that influence the Human Development Index (HDI) in all provinces in Indonesia using multivariable truncated spline nonparametric regression. The Human Development Index is an important indicator in measuring success in efforts to build the quality of human life. The Human Development Index can determine the rank or level of development of a region and a country. In development, a high Human Development Index is something that is expected to be achieved, especially for developing countries. The Human Development Index data used in this study is based on BPS data published in 2020 from all provinces in Indonesia. In this study, based on the results of the analysis, the best nonparametric truncated spline regression was obtained using 1 knot point, 2 knot point and 3 knot point. Based on the minimum Generalized Cross Validation (GCV) value, the best truncated spline regression model is 3 knots with an R2 value of 83.70%. The factors that influence the Human Development Index are the variables expected length of schooling, life expectancy at birth, and population

Children with intellectual disabilities who have limitations and deficiencies in terms of intelligence also have the right to receive education. One of the education provided to children with intellectual disabilities is in the form of a special self-development program with the aim of fostering children's independence. Moderate intellectual disabilities have limitations in the ability to care for themselves, take care of themselves, help themselves, life skills, etc. The research method in this study uses a descriptive qualitative approach research method, while the data collection process in this study uses observation, interview, and documentation techniques. This research was conducted on Monday, December 4, 2023 at 08.00 to 12.00 WIB. The location of the research was carried out at the SLB-E Negeri Pembina, North Sumatra Province, precisely in class XI-1C. The learning strategy for ABK with intellectual disabilities is of course we choose a learning strategy that suits them, because ABK with intellectual disabilities must carry out learning with an individual approach if now using the independent curriculum, actually ABK with intellectual disabilities have been independent learning for a long time. The direct introduction learning strategy for children with special needs and mental retardation is quite effective and can be used as an alternative for children with special needs and mental retardation in carrying out their learning activities.

Indeks pembangunan manusia (IPM) adalah indikator yang digunakan untuk mengukur kemajuan sosial dan ekonomi dalam suatu negara atau wilayah dengan fokus pada kesejahteraan manusia Penulis ingin melihat pengaruh dari variabel independen yaitu Angka Harapan Hidup (AHH), Harapan Lama Sekolah (HLS), dan Rata -rata Lama Sekolah (RLS) terhadap variabel dependen yaitu Indeks Pembangunan Manusia (IPM), dimana data diambil pada web BPS di 11 kabupaten/kota di Provinsi Jambi. Data yang diperoleh tersebut kemudian dianalisis menggunakan analisis regresi linier berganda pada software JASP. Langkah pertama dilakukan dengan mengetahui normalisasi data dari model regresi yang telah, kemudian melakukan uji asumsi klasik yaitu uji Multikolinearitas dan uji heteroskedastisitas. Pada uji multikolinearitas, hanya variabel X1 saja yang tidak multikolinearitas. Langkah selanjutnya yaitu melakukan uji F dan uji t dimana nilai signifikansi atau p-value nya < 0,05. Dari hasil penelitian tersebut diperoleh bahwa Angka Harapan Hidup, Harapan Lama Sekolah, dan Rata-rata Lama Sekolah memiliki pengaruh terhadap Indeks Pembangunan Manusia jika dipengaruhi secara bersama-sama (simultan). Angka Harapan Hidup juga bisa secara sendiri mempengaruhi Indeks Pembangunan Manusia, tetapi untuk Harapan Lama Sekolah dan Rata-rata Lama Sekolah tidak bisa mempengaruhi Indeks Pembangunan Manusia secara mandiri.

This study investigates the need for developing an Islamic character–based supplementary book to improve Arabic speaking skills among students at SMP Islam Al Fahd Jakabaring, Palembang. The background of this research stems from the low communicative competence of students, which is influenced by grammar-dominated instruction and the limited availability of contextual learning materials. The study aims to analyze students’ and teachers’ needs regarding the design of an Arabic supplementary book that integrates Islamic moral values into communicative speaking activities. A qualitative descriptive approach with a needs analysis design was employed. Data were obtained through observations, semi-structured interviews, and questionnaires. The data were analyzed thematically through stages of data reduction, display, and verification to identify key challenges and learning preferences. The findings show that students’ Arabic speaking ability remains at a low to moderate level. Most students can reproduce memorized dialogues but struggle to express ideas spontaneously. Teachers emphasized the absence of instructional materials that provide continuous speaking practice and moral integration. Students also demonstrated greater enthusiasm when learning activities were related to Islamic daily life contexts such as greetings, honesty, and politeness. These results indicate an urgent need for supplementary learning materials that combine linguistic development with Islamic character formation. In conclusion, this study highlights that integrating Islamic values into Arabic language learning materials not only strengthens students’ speaking competence but also supports their moral and spiritual growth. The findings provide a conceptual foundation for future development of value-based teaching resources that align linguistic goals with the broader mission of Islamic education.

Regional development aims to promote economic growth in society, which is commonly measured using Gross Regional Domestic Product (GRDP). Sumatra Island is one of the regions that makes a substantial contribution to national economic growth. However, compared to other provinces in Sumatra, Jambi Province still records a relatively lower GRDP value. In addition, GRDP growth among regencies/municipalities in Jambi Province shows disparities and fluctuates from year to year. This condition reflects variations in the influence of economic factors both spatially and temporally. Spatial variation is indicated by the interregional linkage of GRDP and differences in the economic characteristics of each area, while temporal variation is observed through changes in annual GRDP growth influenced by commodity price fluctuations, development projects, and local economic dynamics. If the analysis is conducted using conventional linear regression without considering spatial and temporal aspects, it may violate classical assumptions, such as the presence of heteroskedasticity, residual autocorrelation, and the inability of the model to capture the dynamics of GRDP changes. This may result in biased and less valid coefficient estimates. This study aims to analyze the effects of Domestic Investment, Human Development Index (HDI), Labor Force Participation Rate (LFPR), Local Own-Source Revenue, and Capital Expenditure on the GRDP of regencies/municipalities in Jambi Province during the 2021–2024 period using the Geographically and Temporally Weighted Regression (GTWR) method. The analysis is carried out through testing spatial and temporal effects, determining the weighting function, estimating parameters, and evaluating model goodness-of-fit using the AIC and R² values. The results show that the GTWR model yields an AIC value of 90.93 and an R² value of 0.526.
