Abstract

Tujuan penelitian ini adalah mengetahui  penyelesaian proses order picking PT. Yamaha Agung Motor Semarang dengan algoritma semut dan mengetahui perbandingan proses order picking PT. Yamaha Agung Motor Semarang yang menggunakan strategi S-Shape dengan algoritma semut dalam menyelesaikan masalah Travelling Salesman Problem (TSP). Metode yang digunakan dalam penelitian ini adalah metode observasi, wawancara, dan studi literatur. Hasil proses order picking dengan menggunakan algoritma semut picker harus menempuh jarak sejauh 52,53 meter dengan waktu berjalan selama 63,036 detik. Sedangkan dengan strategi S-Shape, picker harus menempuh jarak sejauh 70,03 meter dengan waktu berjalan selama 84,036 detik. Berdasarkan hasil penelitian dapat disimpulkan bahwa penggunaan algoritma semut lebih efektif dan efisien dalam mengurangi jarak tempuh aktivitas order picking dibandingkan strategi S-Shape.

Abstract

The accurate understanding of critical thinking and mathematical creativity in solving the current problem is still difficult to standardize. These two thinking skills are indispensable to anyone who is studying mathematics, especially for Undergraduate Mathematics students who are studying Linear Algebra. However, the difficulties in critical thinking discourage students to think creatively and mathematically. In linear algebraic subject matter, many problems require critical reasoning. It goes without saying that the difficulties in various reasoning aspects critically cause other difficulties in developing creative thinking aspects. Further, mathematical critical thinking skills in solving problems require a background in understanding the concepts related to the problem faced. In addition, the failure to understand and connect between concepts in solving linear algebra problems makes it worst and difficult to critically and creatively think.

Abstract

Penelitian ini mengkaji sebuah permasalahan pencarian solusi optimum untuk masalah Travelling Salesman Problem (TSP). Tujuan dari penelitian ini adalah meneliti salah satu kasus TSP pada masalah penentuan rute objek wisata di Kota Semarang menggunakan algoritma Branch and Bound dan diaplikasikan ke dalam program winQSB. Pengambilan data dilakukan dengan cara melihat peta Kota Semarang yang diperoleh dari Dinas Kebudayaan dan Pariwisata Kota Semarang. Data yang diambil berupa beberapa lokasi wisata, selanjutnya dilakukan pencarian jarak dengan bantuan Google Maps. Analisis data dilakukan dengan menggunakan mekanisme algoritma Branch and Bound yang kemudian diaplikasikan dalam program winQSB. Dari analisis yang telah dilakukan, dengan cara perhitungan manual maupun dengan bantuan program winQSB rute terpendek yang dapat diperoleh yaitu melalui jalur Masjid Agung Jawa Tengah-Water Blaster-Simpang Lima-Lawang Sewu-Sam Poo Kong-Taman Margasatwa Mangkang-Gereja Blenduk dan kembali ke Masjid Agung Jawa Tengah dengan jarak minimum 53,2 kilometer dalam sekali tempuh. Dari hasil analisis, diharapkan biro perjalanan yang ada di Kota Semarang dapat menerapkan metode perhitungan rute optimal agar dapat mengetahui jalur terpendek dari sejumlah objek wisata.

Abstract

Pemrogaman bilangan bulat (integer progamming) yang hanya mempunyai satu pembatas dikenal sebagai masalah knapsack (knapsack problem). Metode untuk menyelesaikan permasalahan tersebut adalah algoritma Branch and Bound. Algoritma Branch and Bound secara sistematis mengabaikan sekumpulan kandidat solusi yang tidak potensial menuju solusi optimal menggunakan estimasi batas atas dan bawah (upper and lower estimated bounds) dari kuantitas yang dioptimasi. Alat bantu yang dapat digunakan adalah software Lingo 11.0. Dalam tulisan ini akan dikaji bagaimana cara untuk mengoptimalkan muatan barang agar memperoleh keuntungan yang maksimal. Penyelesaian permasalahan Knapsack 0-1 berdasarkan studi kasus di CV Pangestu Interaksi Semarang dengan menggunakan algoritma Branch and Bound diperoleh solusi optimal x*=(1 ,1 ,1 ,1 ,0,1 ) dan nilai optimal z*=1 1 30000 yang ditemukan pada submasalah 1 , step kesembilan (t=9).

Abstract

This study aimed to determine the 7th grade students’ mathematical connections ability through CMP learning models to achieve learning mastery; to know whether the 7th grade students’ mathematical connections ability through CMP learning model was better than CMP learning model without educational tools; to know the student's questioning-skill factors; and to know the description of the ability of mathematical connections viewed from the 7th grade students' questioning-skills through the CMP learning model. The research method used was mixed method of the concurrent embedded model. The population in this research were all 7th-grade students of SMP Negeri 3 Semarang. The sample of research was taken from 7D and 7F classes. Subjects of this study were as many as 6 subjects with each of 2 subjects chosen from each category of questioning-skills. The results of the research showed that students' mathematical connection ability through the educational tools in CMP model learning achieved learning mastery; students' mathematical connection ability through CMP learning model was better than CMP learning model without the educational tools; the factors that influenced the students' questioning-skill were willingness within students, the use of educational tools, project-based learning/problem, and the response given by the teacher when students asked; and students' mathematical connection ability through CMP learning model viewed from questioning-skills indicated that students with high questioning-skill had best mathematical connection ability, followed by students with medium questioning-skill, and low questioning-skill.

Abstract

To the purpose research is determine solution to optimize water processing with controls chart as tool of observation and Euler method to substance dissolution on that case so acquired maximum gain. Observational method that is utilized is case study. Data that is taken is pH and muddiness of water. Hereafter been done analisis data by use of chart controls statistika to conduct quality and euler method on that case so acquired maximum water processing. From analisis extrapolation that did by controls chart to utilize program Visual Basic on pH's data is gotten xbar = 228,49, Rbar= 10,6, LKA = 7,94,xdoublebar = 7,62 and LKB = 7,29. On pH's graph has no dot out of the sphere LKA and LKB, therefore said by means controlled process its pH's quality uninfluenced by a cause. Meanwhile on muddiness data is gotten xbar = 6820,56,Rbar = 23048, LKA = 513,572 and = 227,35 and LKB = 0. On muddiness graph exists dots out of the sphere LKA and LKB as dot 1, 9, 15, and 17, therefore said by process is not controlled by its mean muddiness quality regarded by a cause. Taking conclusion from chart's purpose controls this with action issues quality cause that took in by outboard dot controls its mean take a decision production will be discontinued at the moment that condition.

Abstract

Mathematical problem-solving ability is one of the goals of mathematics learning. However, the mathematical problem-solving ability of students is still lacking. Therefore, this research was conducted (1) to observe whether students problem-solving ability on CORE-modeled mathematical learning passed the minimum criteria of mastery learning or called as KKM included average mastery and proportion mastery, (2) compare the application of CORE model and Jigsaw model on students problem solving ability, (3) increase the mathematical problems solving ability using CORE model and (4) analyze the mathematical problem solving ability observed from hard work character using CORE model. This research used a mixed method with the concurrent triangulation method. The population was VIII grade student of SMPN 12 Semarang. The results showed that: (1) the mathematical problems solving ability on CORE-modeled mathematical learning passed the minimum criteria of mastery learning included average mastery and proportion mastery, (2) students problem solving ability on CORE mathematics learning model and those on Jigsaw mathematics learning model are equal, (3) there was an increase in the mathematical problems solving ability on mathematics learning after CORE model being applied, (4) student who had worked hard trait in the 1st group on mathematics learning showed the ability to solve mathematical problems was better than those in 2nd and 3rd group on mathematics learning.
