Penelitian ini adalah penelitian kuantitatif dengan jenis penelitian quasi eksperimen. Populasi penelitian ini seluruh siswa kelas XI IPS. Alat pengumpulan data berupa tes berbentuk uraian. Teknik pengambilan sampel yang digunakan yakni Non-Probability Sampling. Sedangkan teknik analisis data digunakan uji-t yang diawali dengan menghitung rata-rata, menghitung standar deviasi, uji normalitas, homogenitas, dan uji hipotesis. Temuan penelitian khusus tidak ditemukan perbedaan yang signifikan terhadap hasil belajar dengan menggunakan strategi pembelajaran kooperatif tipe Think Talk Write (TTW) dan Numbered Head Together (NHT). Hal ini dapat dilihat dari nilai rata-rata post test pada kelas eksperimen I sebesar 82,77 dan nilai rata-rata post test pada kelas eksperimen II sebesar 76,75 serta nilai T hitung =0,84696 < T tabel=2,021. ABSTRACK This research is a quantitative research with a quasi-experimental type of research. The population of this study were all students of class XI IPS. The data collection tool is in the form of a test in the form of a description. The sampling technique used is Non-Probability Sampling. While the data analysis technique used t-test that begins with calculating the average, calculating the standard deviation, normality test, homogeneity, and hypothesis testing. Specific research findings found no significant differences in learning outcomes using cooperative learning strategies Think Talk Write (TTW) and Numbered Head Together (NHT) types. This can be seen from the average post-test value in the experimental class I of 82.77 and the post-test average value of the second experimental class of 76.75 and the calculated T value = 0.84696 < T table = 2.021.

The penetrating waterbird on the east coast of North Sumatra is Egretta Garzetta. It is a kind of water bird that lives in water or parts of wetlands. The presence of waterbirds is an important indicator to evaluate the environmental quality and productivity of wetlands. Bird distribution patterns are needed to overcome problems related to habitat, such as food availability and population size. This study aims to apply themethod Nearest Neigbord Analysis to the distribution pattern of Egretta Garzetta in the Mangrove area of North Sumatra. This study uses a quantitative approach to the type of applied research (Applied Research). The type of data used in this research is secondary data. Analysis of the data in this study using Nearest Neighbor Analysis. The pattern of the spread of Egretta Garzetta in the Mangrove areas in North Sumatra have clumped pattern (clustered).The results from Nearest Neighbor Analysis show that the index value of the clustered distribution pattern can be caused by the abundance of food sources in a habitat.

This study aims to determine the effect of Problem Based Learning model on students' mathematical computational thinking ability. The sample of this study involved 8th grade students of Madrasah Tsanawiyah (MTs) Hifzhil Qur'an Yayasan Islamic Centre Sumatera Utara in the 2023-2024 school year totaling 53 people. The sampling technique used was cluster random sampling so that researchers had 2 class groups, namely class 8-3 as the experimental class and class 8-4 as the control class. The method used is quantitative experimentation with a research design in the form of True Experimental Design in the form of Post-test-Only Control Design. The analysis of this study used Independent Sample t Test and obtained a sig value. <0,001. Thus H0 is rejected and Ha is accepted, meaning that there is a significant effect of using Problem Based Learning model on students' mathematical computational thinking skills.

A Nonparametric regression with a truncated biresponse spline approach is a good method in solving the problem of unknown shape of the regression curve. Truncated splines provide high flexibility in estimating curves that have data patterns that tend to change at certain intervals and do not require classic assumption tests. The purpose of this study was to obtain the best biresponse truncated spline regression model for North Sumatra's inflation and GRDP. This study uses qualitative methods and uses secondary data obtained from the Central Bureau of Statistics of North Sumatra. Selection of the best model is determined based on the optimal knot point using the minimum GCV value criteria. The research results obtained are the best spline model with 3 knot points with an MSE value of 1.6028 and a minimum GCV value of 0.0452. The value of response 1 is 14.64% and response 2 is 61.85%. This means that the ability of the predictor variable to explain the variance of the response variable is 14.64% and the remaining 61.85% is influenced by other factors.
