Abstract

This research was done to predict the cumulative achievement index of students STMIK Royal Kisaran is based on students' academic history at the time of senior high school. This research will inform the student for early anticipation in following the lecture in order to get the maximum learning. The method used in solving this problem is by the method Decission tree C.45 algorithm starts from the formation of the decision system as preliminary data have attribute values and decision condition. Then calculate the entropy of each attribute. Calculating the highest gain value which would then be used as nodes. Determining Following the decision of the result tree Decission process using if-then logic begins from the highest to the root of the lowest roots. This research resulted in 7 pieces of pattern rules (rule) as a basis for predicting student achievement of learning outcomes. Keywords: data mining, algorithm C.45, learning Outcomes.

Abstract

Abstract: This study aims to solve the problem of transportation costs for Bagus Bakery and Early Bakery producers by using the Stepping Stone model transportation method. The first step in completing the minimum transportation costs is to form the distribution costs, the amount of production and demand into the transportation model. Furthermore, the transportation model was analyzed using the stepping stone model. The application of the distribution transportation model using the stepping stone model can provide a solution for bakeries in optimizing bread distribution costs of 68,550 IDR. Thus in the calculation process using the Stepping Stone it turns out that it can minimize transportation costs with a difference in costs of 81,450 IDR. Keywords: transportation method, stepping stone Abstrak: Penelitian ini bertujuan untuk menyelesaikan permasalahan biaya transportasi produsen Bagus Bakery dan Dini Bakery dengan menggunakn metode transportasi model Stepping Stone. Langkah pertama dalam menyelesaikan biaya transportasi yang minimum adalah membentuk biaya pendistribusian, jumlah produksi dan permintaan kedalam model transportasi. Selanjutnya model transportasi dianalisis menggunakan model stepping stone. Penerapan model transportasi distribusi dengan menggunakan model stepping stone dapat memberikan solusi pada toko roti dalam pengoptimalan biaya distribusi roti sebesar Rp 68.550. Dengan demikian pada proses perhitungan dengan menggunakan Stepping Stone ternyata dapat meminimumkan biaya transportasi dengan selisih biaya sebesar Rp 81.450. Kata kunci: metode transportasi, stepping stone

Abstract

Abstract: This research was conducted on grade VI students of Al Washliyah Elementary School Cab XII Sei Kepayang with the aim of improving student learning outcomes through the implementation of the learning process that applies the Make a Match type cooperative learning model on whole number counting operation material in grade VI of Al Washliyah Elementary School Cab XII Sei Kepayang. The type of research is Classroom Action Research which is conducted in two cycles. The data obtained in this study are student learning outcomes taken from giving learning outcomes test questions at the end of each cycle and observation sheets in each cycle. The results of the research in cycle I showed a percentage of classical completeness of 55% with eleven students who reached the KKM. While the research results in cycle II showed the percentage of classical completeness of 87.7% with eighteen students who reached the KKM. From this study it was concluded that by applying the cooperative learning model of the make a match type, the learning outcomes of grade VI students of Al Washliyah Elementary School Cab XII Sei Kepayang in the 2023/2024 academic year on the material of counting operations of whole numbers.Keywords: integers, Make a Match, number operations.Abstrak: Penelitian ini dilaksanakan pada siswa kelas VI SD Al Washliyah Cab XII Sei Kepayang bertujuan guna mengingkatkan hasil belajar siswa melalui pelaksanaan proses pembelajaran yang menerapkan model pembelajaran kooperatif tipe Make a Match pada materi operasi hitung bilangan bulat kelas VI SD Al Washliyah Cab XII Sei Kepayang. Adapun jenis penelitian ini adalah Penelitian Tindakan Kelas yang dilaksanakan dalam dua siklus. Data yang diperoleh dalam penelitian ini adalah hasil belajar siswa yang diambil dari pemberian soal tes hasil belajar pada akhir setiap siklus dan lembar observasi pada setiap siklus. Hasil penelitian pada siklus I menunjukkan persentase ketuntasan klasikal 55% dengan sebelas siswa yang mencapai KKM. Sedangkan hasil penelitian pada siklus II menunjukkan persentase ketuntasan klasikal 87,7% dengan delapan belas siswa yang mencapai KKM. Dari penelitian ini disimpulkan bahwa dengan diterapkan model pembelajaran kooperatif tipe make a match maka hasil belajar siswa kelas VI SD Al Washliyah Cab XII Sei Kepayang tahun pelajaran 2023/2024 pada materi operasi hitung bilangan bulat. Kata kunci: bilangan bulat, Make a Match, oprasi bilangan.
