Abstract

Abstrak. Travelling Salesman Problem (TSP) adalah permasalahan dimana seorang salesman harus mengunjungi semua kota yang mana tiap kota hanya dikunjungi sekali, dan harus kembali ke kota asal. Masalah utama yang dihadapi sebuah TSP adalah bagaimana mencari rute terpendek dari perjalanan seorang salesman dengan biaya minimum. Penelitian ini bertujuan untuk mengetahui penyelesaian masalah TSP dengan menggunakan algoritma Hill Climbing baik Simple Hill Climbing (SHC) maupun Steepest-Ascent Hill Climbing (SAHC). Berdasarkan hasil kajian teori yang dilakukan, dapat disimpulkan bahwa algoritma Hill Climbing dapat digunakan untuk menyelesaikan TSP. Algoritma Hill Climbing dalam menyelesaikan masalah TSP yaitu: menentukan initial state, melakukan pengujian panjang lintasan, melakukan kombinasi penukaran dua kota, dan kemudian melakukan pengujian terhadap nilai heuristiknya. Penyelesaian masalah TSP dengan menggunakan algoritma Hill Climbing masing-masing mempunyai karakteristik yang berbeda-beda. Dalam menyelesaikan masalah TSP, SHC memilih keadaan yang lebih baik tanpa melakukan pengujian dikombinasi pertukaran kota pada iterasi yang sama. Sedangkan SAHC membandingkan keadaan yang lebih baik sebelum memilih keadaan tersebut sebagai new state. Selanjutnya untuk membantu proses komputasi pada saat menyelesaikan TSP, dibuat sebuah program dengan model algoritma Hill Climbing menggunakan MATLAB. Program yang terbentuk memberikan solusi berupa rute perjalanan yang disajikan dalam bentuk diagram.Kata kunci: Algoritma, Hill Climbing, Travelling Salesman ProblemAbstract. (Completion of Traveling Salesman Problem (TSP) Using the Hill Climbing and MATLAB Algorithms) Traveling Salesman Problem (TSP) is a problem where a salesman must visit all cities where each city is visited only once, and he/she must return to the hometown. The main problem facing a TSP is how to find the shortest route of a sales trip with minimum cost. This study aims to determine the solution of TSP problems using Hill Climbing algorithm both Simple Hill Climbing (SHC) and Steepest-Ascent Hill Climbing (SAHC). Based on the result of the theoretical study, it can be concluded that Hill Climbing algorithm can be used to solve TSP. Hill Climbing algorithm in solving TSP problem is: determining initial state, conducting track length test, performing combination of two city exchanges, and then testing the heuristic value. TSP problem solving using Hill Climbing algorithm each have different characteristics. In solving the TSP problem, SHC chooses a better state, without performing tests in combination of city exchanges on the same iteration. While SAHC compares the situation better before choosing the state as a new state. Furthermore, to assist the computing process when completing the TSP then made a program model Hill Climbing algorithm using MATLAB language. The program is formed to provide solutions in the form of travel routes presented in the form of diagrams.Keywordsi: Algorithm, Hill Climbing, Travelling Salesman Problem

Abstract

Ethnomathematics objects can be found in artifacts in the form of historical buildings. One of the historical buildings in Kotagede, Yogyakarta, Indonesia, is the Beteng Cepuri fortress. The purpose of this research is to conduct an exploration of any mathematical concepts contained in Beteng Cepuri that can be used as a source of learning mathematics as an effort to develop ethnomathematics for learning elementary school mathematics. The researchers invited the fifth-graders of an elementary school in Kotagede, nearby the Cepuri Beteng, to explore and learn mathematical concepts. The results show that there is a relationship between the construction of the fort building and the concept of geometry in several parts of the Cepuri Beteng. The sections are in the form of cuboids and rectangles. Taking the students to visualize the artifacts may assist them to build 3D shape recognition. It can be concluded that ethnomathematics is able to create a very good interest in learning followed by concept acquisition.
