Abstract. This study discusses the influence of the scientific approach to mathematical learning outcomes. The type of research used in this writing is quasi-experimental, with scientific approach data collection on students' mathematical learning outcomes. Data analysis used with Simple Regression Analysis Test. Based on the analysis obtained by the results of the study, namely: the relationship or correlation between learning approaches with student learning outcomes with regression , with . The values for testing the data can use the Anova table   and the significance level of 0.000 < 0.05. So that it can be said that the values of the two data are different. Thus, it can be concluded that there is the influence of the scientific approach to students' mathematical learning outcomes. This shows that the learning approach has a significant effect on students' mathematical learning outcomes. The coefficient of determination is   means that the contribution or influence of the santifik approach (X) on the students' mathematical learning outcomes (Y) is . Thus, the scientific approach is better at contributing to students' mathematical learning outcomes.Keywords: Scientific Approach, Learning Outcomes

Penelitian ini membahas tentang pengembangan model pembelajaran saintifikberbantuan alat peraga paparaga baret untuk meningkatkan minat belajar siswa. Penelitian ini bertujuan untuk mengembangkan model pembelajaran saintifik berbantuan alat peraga papan ular tangga pada materi barisan dan deret aritmatika. Alat peraga yang dikembangkan memenuhi kriteria kevalidan, kepraktisan dan keefektifan media menggunakan model pembelajaran saintifik dapat meningkatkan minat belajar siswa dalam pembelajaran pada siswa kelas X. Penelitian ini merupakan penelitian pengembangan (Research and Development) yaitu pengembangan model pembelajaran saintifik berbantuan alat peraga papan ular tangga. Penelitian ini menggunakan model pengembangan 4d yang dikembangkan oleh S. Thiagarajan, tetapi peneliti hanya menggunakan 3 langkah pengembangan yaitu (define, design, development). Tekhnik pengumpulan data yang digunakan dalam penelitian adalah metode angket dan soal pretest, posttest.  Penelitian ini menghasilkan alat peraga berupa papan ular tangga barisan dan deret aritmatika. Hasil analisis tingkat kelayakan pada papan ular tangga barisan dan deret menunjukkan bahwa (1) Uji validitas dari ke 4 ahli menunjukkan rata-rata 79,07% sehingga alat peraga berupa paparaga baret masuk kedalam kategori valid. (2) Uji kepraktisan dilihat dari angket respon siswa dinyatakan sangat praktis dengan rata-rata 84,92%. (3) Uji keefektifan dinyatakan sangat efektif dilihat dari uji soal pretest dan posttes dengan nilai rata-rata 82,46% siswa yang tuntas. Sedangkan pada angket respon terhadap media untuk meningkatkan minat belajar siswa nilai rata-rata 55,94% menunjukkan bahwa minat belajar siswa tinggi. Dari ketiga uji dan respon terhadap media untuk meningkatkan minat yang telah dilakukan maka dapat disimpulkan bahwa paparaga baret layak digunakan sebagai media pembelajaran

According with the development of information technology and the expand of the internet in the community, the need for computers is very important to support the increasingly high utilization of information technology. Processing data and information requires speed and accuracy of data, to achieve it, it is requires an information technology that can support work so the work becomes more effective and efficient. PT. PLN (Persero) Krueng Geukueh District is a company that runs in the area of electricity and provides services to the community in the provision of services related to electricity, which has a large number of customers. The process of managing customer data at PT. PLN (Persero) Krueng Geukueh District has used a customer data system, but still has a disadvantage of requiring more time in searching customer data, to solving this problem, the author designed the development of the system using the string matching algorithm method, which is one of the most important parts in various processes related to data and text types, one of which is the search for words in customer data. The performance of the string matching algorithm is to match a letters per letter with the keywords given by the staff. The results of this study indicate that by using this method, searching for customer data can be easier. With the development of this system, it is expected that staff or admin in the company can do the work more effectively and efficiently.

This community service activity program aims to improve the skills of teachers in making learning media during the pandemic at SMAN 1 Rantau Utara. The method used is descriptive method. The steps used are by providing socialization, lectures and assistance in the process of making learning media during the pandemic. The results of the response of the training participants gave a positive response. Participants gave suggestions in this activity to continue in self-development for teachers at SMAN Rantau Utara.
