REKONSTRUKSI MODEL PROGRAM NONLINIER DENGAN FUNGSI POLINOMIAL MENJADI BENTUK PROGRAM KUADRATIK
Full text linkThe purpose of this research to revisits methods that are more effective in nonlinear Optimization with single variable polynomial functions at high degrees. Models with linear objective functions and constraint functions are Polynomials of third, fourth and fifth degree reconstructed into subproblems that are easier to solve, namely quadratic programs, using bilinear Auxiliary Functions and solved by MATLAB simulations. The method used is the development of Tawarmalani & Sahinidis' research regarding relaxation with Auxiliary Functions. Examples of nonlinear Optimization with polynomial functions are also given to illustrate the implementation of this algorithm. The results of the research show that the application of the development reconstruction method produces a global solution that is no better than the solution to the original problem so that it is not an effective alternative method to use

Analisis Kebutuhan Mahasiswa Terhadap Bahan Ajar Sebagai Acuan Untuk Mengembangkan E-Module Pembelajaran Koperasi
Full text linkPenelitian ini bertujuan untuk menganalisis kebutuhan mahasiswa terhadap bahan ajar yang digunakan dalam kegiatan perkuliahan Pembelajaran Koperasi. Penelitian ini merupakan penelitian deskriptif eksploratif dengan subjek penelitian adalah mahasiswa pendidikan ekonomi semester enam FKIP Universitas Musamus sebanyak 25 orang mahasiswa. Data penelitian diperoleh dari kegiatan observasi awal dan pengisian angket kebutuhan terhadap bahan ajar yang diinginkan. Hasil observasi awal menunjukkan bahwa pada materi perkuliahan Pembelajaran Koperasi akan lebih banyak melakukan praktik dalam membuat perhitungan SHU namun dikarenakan waktu perkuliahan yang terbatas hanya dua sks disetiap pertemuan membuat dosen kesulitan untuk memberikan penjelasan materi secara rinci kepada mahasiswa. Hasil analisis angket mahasiswa menunjukkan bahwa mahasiswa lebih membutuhkan bahan ajar jenis digital berupa modul agar dapat menjadi penunjang dalam kegiatan perkuliahan mahasiswa dan dapat digunakan mahasiswa dalam kegiatan perkuliahan secara mandiri maupun dengan pendampingan dosen mata kuliah
Pengaruh Pendekatan Realistic Mathematic Education (RME) Terhadap Kemampuan Pemahaman Konsep Matematis Siswa
Full text linkThis study aims to determine the effect of the Realistic Mathematical Education (RME) approach on the ability to understand mathematical concepts in class VIII students of SMP IT Al-Hijrah 2 Deli Serdang Private Middle School in the 2022/2023 academic year. The type of research used is Quasi Experimental with a Pretest-Posttest Control Group Design. The sample used was 35 students who were selected through a purposive sampling technique. Data collection techniques are carried out using test instruments. Data analysis technique is done by descriptive analysis. The results of the descriptive analysis show that the average value in the experimental class is 87.3935 and in the control class is 54.3639, which means that there is a difference in the posttest average scores in the experimental class and the control class. Based on the Independent Sample T-Test, the value of Sig. (2-tailed) of 0.000 < 0.05. The tcount value is 8.428 and the ttable value is 2.03452, which means that tcount > ttable then H0 is rejected and Ha is accepted.

Kajian Sosiologi Sastra: Bentuk Interaksi Sosial Antar Tokoh Dalam Novel Lebih Senyap Dari Bisikan Karya Andina Dwifatma
Full text linkThis research aims to analyze the form of social interaction between characters in the novel Lebih Senyap Dari Bisikan by Andina Dwifatma, and utilize the results of the analysis as an alternative teaching material for SMA class XII students. This research is a descriptive qualitative research whose analysis results will be described narratively. The data source in this analysis is the novel Lebih Senyap Dari Bisikan by Andina Dwifatma. The findings of the analysis show that this novel contains social interactions that are associative and dissociative. Associative social interaction consists of cooperation when the characters realize that they have the same interests, accommodation when the characters are willing to adjust to the new environment, and assimilation when the characters try to reduce differences. Meanwhile, dissociative social interactions consist of contravention when the characters cause disagreement with each other, and conflict when the characters oppose each other by hitting each other. The results of the analysis are then adjusted to the demands of the 2013 curriculum based on Core Competencies and Basic Competencies and made a product in the form of teaching materials to support the learning of SMA class XII students

Pengaruh Hubungankemampuan Komunikasi dan Penalaran Matematika Siswa Kelas VIII Terhadap Hasil Belajar Yang Diajar Dengan Model Pembelajaran Group Investigation (GI)
Full text linkThis study aims to determine whether there is a positive and significant effect of the Group Investigation type cooperative learning model on students' mathematical reasoning and communication skills in the Pythagorean Theorem sub-subject in class VIII SMP Negeri 1 Munte in the 2019/2020 Academic Year. The population in this study were all class VIII students of SMP Negeri 1Munte for the 2019/2020 Academic Year. While the sample in this study consisted of 2 classes of 38 students each in class VIII-1 as the experimental class and class VIII-3 as the control class. The experimental class uses the Group Investigation cooperative learning model consisting of 5 students per group, and the control class uses the Group Investigation type cooperative learning model consisting of 2 students per group. This type of research is an experiment. Prior to testing the hypothesis, the normality and homogeneity tests are tested first. Normality was tested using the Lilliefors technique and homogeneity using the F test. From the tests performed, it was found that both samples were normally distributed and homogeneous. There is a positive and significant influence of the Group Investigation cooperative learning model on the mathematical reasoning abilities of junior high school students. There is a positive and significant influence of the Group Investigation type of cooperative learning model on the mathematical communication skills of junior high school students because the average communication ability of students who are taught with the Group Investigation type cooperative learning model consisting of 5 people per group is higher than the average communication ability of students who are taught with the Group Investigation type cooperative learning model consisting of 2 people per grou
