Abstract

Tujuan Penelitian ini adalah untuk menentukan rute pendistribusian bantuan logistik untuk warga yang terdampak korban bencana gempa dan tsunami di Palu, Donggala dan Sigi dari pos koordinasi MDMC (Muhammadiyah Disaster Management Center) ke pos-pos pelayanan dengan menggunakan metode Saving Matriks.Salah satu metode yang digunakan untuk menyelesaikan masalah ini adalah Metode Saving Matriks. Metode ini merupakan metode penentuan rute terpendek dengan mengoptimalkan rute distribusi sehingga mampu menghemat jarak dan meminimalkan biaya trasportasi. Objek penelitian yaitu pos koordinasi dan pos-pos pelayanan MDMC. Variabel yang digunakan yaitu jarak, biaya, armada yang tersedia, kapasitas muatan tiap armada, permintaan bantuan dan rute awal.Hasil penelitian menyimpulkan bahwa hasil perbandingan rute yaitu rute awal dari data matriks awal dan Saving Matriks yang diolah hingga mendapatkan rute Saving Matriks, diperoleh persentase penghematan jarak, bahan bakar dan biaya distribusi sebesar 44,31 % dari jumlah pada rute awal . Selain itu, rute terbaru menggunakan Saving Matriks mampu mengurangi penggunaan armada atau sarana distribusi dan mengoptimalkan rute.

Abstract

The purpose of this study is to determine the interaction between learning process and early mathematical ability towards the enhancement of mathematical disposition ability, and for knowing the enhancement of student's mathematical disposition ability who achieved Chalk Talk method with CTL approach compared conventional learning. The type of this research is quasi-experiment with non-equivalent control group design. The independent variable of this study is Chalk Talk with CTL and early mathematical ability. The dependent variable of this study is mathematical disposition ability. The sample of this study is the student from SMP Muhammadiyah 3 Depok grade VIII, then VIII B and C as the sample. The instrument use scale of mathematical disposition ability and activity note. The data analysis using ANOVA 2 tail technic (significance 5%). The results of this study indicate that there is no interaction between learning and early mathematical ability on enhancing mathematical disposition ability of student, and the enhancement of student's mathematical disposition ability that received Chalk Talk with CTL was not better than student who received conventional learning

Abstract

Critical thinking skills are very important for students in the 21st century. The development of HOTS-based cognitive assessment instruments aims to produce assessment instruments that are valid, practical, and effective evaluation tools. This development research modified Thiagarajan's 4-D model with stages: define, design, develop, and disseminate. After revision and approval by experts, the instrument design draft was analyzed. After that, a limited test was carried out on a total of 34 students in class XI Science 1 at SMA Negeri 9 Pangkep. Tests, questionnaires, interviews, and observations were the methods used in data collection. The research results showed that: (1) the validity of the HOTS-based cognitive assessment instrument was in the very valid category with a score of 93.33% from the media aspect and 92% from the material aspect; (2) the assessment instrument developed was in the very practical category which was obtained from the results of student responses with a percentage of 82.35% and teacher responses with a percentage of 88%; and (3) the effectiveness of the instrument was in the effective category obtained from test data on student learning outcomes of 73.52% in the effective category, and students' critical thinking abilities were on average in the good category. Based on the results obtained, a conclusion was drawn that the HOTS-based cognitive assessment instrument meets the criteria for validity, practicality, and effectiveness.
