Student learning outcomes can be influenced by internal and external factors. The purpose of this study was to determine the increase in student learning outcomes with inquiry-based learning and the effect of age and motivation on learning outcomes. The research population was all students of chemical tadris who were taught atomic structure in the even semester of the 2022/2023 academic year. The sample of this research was all chemistry students at UIN Syekh Ali Hasan Ahmad Addry Padangsidimpuan with a total of 23 students. Analysis of research instruments and testing the research hypothesis using the SPSS 22 for windows program. The results showed that student learning outcomes increased with learning inquiry and age and motivation factors did not affect student learning outcomes where Sig. (2-tailed) > α (0.938 > 0.05) and (0.513 > 0.05) means that the hypothesis is rejected with a significant level of 5%.

Hasil obeservasi yang dilakukan siswa mengalami kesulitan membedakan kalor dan suhu serta sulit membedakan reaksi eksterm dan endoterm yang ada pada materi termokimia. Sehingga penelitian ini dilaksanakan yang bertujuan untuk membuktikan pengaruh media kartu soal dan ular tangga yang menggunakan paradigma pembelajaran Teams Games Tournaments (TGT) terhadap hasil belajar siswa ketika digunakan untuk mengajarkan termokimia. Penelitian ini merupakan penelitian eksperimental. Setiap siswa kelas XI yang diajarkan termokimia pada semester , memanfaatkan sumber daya dari kurikulum K–13 menjadi sampel penelitian. Dua kelas di SMA Negeri 10 Medan, masing-masing dengan tiga puluh siswa, menjadi sampel penelitian. Instrumen penelitian yang digunakan adalah tes hasil belajar siswa pada aplikasi SPSS 22 Windows digunakan untuk mengevaluasi instrumen penelitian dan menguji hipotesis penelitian. Menurut temuan penelitian, pada tingkat signifikansi 5%, siswa yang diajar menggunakan kartu soal (84,00) mengungguli mereka yang diajar menggunakan ular tangga (78,33) dalam hal hasil belajar. Maka dapat disimpulkan bahwa hasil belajar siswa yang dibelajarkan dengan media kartu soal lebih baik daripada hasi belajar siswa yang menggunakan media ular tangga pada pembelajran termokimia dengan menggunakan model pembelajran Team Games Tournament.

Indonesia is known as a country with many natural and man-made tourist destinations, especially the South Tapanuli region which has marine, natural and man-made tourist destinations that are attractive and worth visiting for domestic and foreign tourists. In 2023, the number of tourists visiting South Tapanuli will be 422,688 people. This research aims to estimate or predict the number of tourists visiting South Tapanuli in the next 6 years using the Double Exponential Smoothing (DES) method with amortized parameters. Double exponential smoothing (DES) is a forecasting method by predicting time series data with a trend model. To overcome overprediction, an attenuating parameter is added which can reduce the estimated value exponentially. This research also aims to compare the estimated number of tourists in South Tapanuli Regency using the T test. This research shows that the estimated number of tourists coming to South Tapanuli Regency in the next six years will increase. For the t test carried out, the results obtained were tcount < ttable (2.014 < 2.015).

This research aims to determine the creative thinking skills of students who are taught using web media, guided inquiry learning combined with lesson study, which is higher than without using web media. And knowing that the learning outcomes of students taught in guided inquiry learning combined with lesson study using web media are higher than without using web media. The research population was students of class XI Science High School. The sampling technique was simple random sampling consisting of two classes, namely experimental and control with a total sample size of 76 students. This research instrument is a creative thinking test and student learning outcomes. Data analysis techniques are carried out by calculating the level of concept understanding, testing data homogeneity, normality testing and hypothesis testing. The results of the research show that the learning outcomes and creative thinking of students taught in combination lesson study inquiry learning using web media with an average gain of 0.71 and an average of 75.46 compared to without using web media with an average of 0.60 and 55. .20 with significance (0.00 0.05).

Indonesia is a country that has a good source of clean water. But do not escape from water pollution caused by population density which is increasing from day to day. This has led to an increasing consumption of water as well as consumption of water in households and in industry. The presence of metals such as Fe (iron), Al (aluminum) and Cr (chromium) in the community's water can be a concern for the health of the residents of Aek Godang and its surroundings. Under these conditions, an experiment was carried out with the aim of analyzing the content of the population's water sources (dug well water, drilled well water, river water) using TDS and water electrolyze tools. The results of this study indicate that the water sources of the Aek Godang community have TDS levels of 24 mg/L and 23 mg/L so that it can be concluded that the water sources of the Aek Godang community are in the good category.
