Support Vector Machine (SVM) adalah metode klasifikasi yang efektif dan kuat, terutama ketika diterapkan pada data berdimensi tinggi. Namun, data berdimensi tinggi sering kali mengandung fitur-fitur yang tidak relevan, sehingga kinerja SVM menjadi tidak optimal. Oleh karena itu, diperlukan proses seleksi fitur sebagai solusi untuk mengoptimalkan ki...
The rainbow connection number, denoted by rc(G), is the minimum number of colors required to color the edges of a graph G such that the graph is rainbow connected. A graph G is said to be rainbow connected if every pair of vertices in the graph has at least one rainbow path, a path in which each edge has a different color. Rainbow coloring has been...
With its complex topography, Gorontalo Province experiences significant rainfall variations that impact the agricultural sector, particularly rice crops. These variations can cause substantial losses for farmers. One way to address uncertain probabilities caused by rainfall is through agricultural insurance. This research aims to calculate the valu...
This study models daily wind speed transitions in the Bone Bolango Regency using the Markov Chain Monte Carlo (MCMC) method and the Metropolis-Hastings algorithm, employing the Beaufort scale for wind speed classification. The research aims to predict the steady-state distribution of wind speeds and evaluate their temporal stability. Daily wind spe...
Industri pariwisata di Indonesia saat ini perkembangannya begitu pesat sehingga membutuhkan sistem informasi yang dapat mempermudah wisatawan sebelum melakukan perjalanan wisata. Penelitian ini bertujuan untuk menghasilkan dan mengaplikasikan sistem pendukung keputusan berbasis website yang membantu wisatawan dalam mennetukan destinasi wisata yang...
A child displaying symptoms of dyslexic learning disorders requires assistance in accurately identifying numbers, particularly those that share resemblances. This research aimed to develop media for teaching dyslexic children to help them identify numbers correctly. This research employed a development and single-subject research method. The subjec...
Let G be a simple and finite graph. Rainbow connection and total rainbow connection c are set c : G → {1,2,. . . , k} where k is the minimal color on graph G. A rainbow connection number(rc) is a pattern by giving different colors to the connection edges (E(G)) so that a rainbow path is formed. The total rainbow connection number (trc) is a payment...
Geographically Tihu village is located on the coast where the majority of its residents work as fishermen. Skipjack tuna is a type of fish that is abundant in Tihu village. The habit of fishermen distributing their catch to consumers causes the economic value of sales to be less than optimal. Processing skipjack tuna into shredded fish and nuggets...
Rainbow vertex-connection number is the minimum colors assignment to the vertices of the graph, such that each vertex is connected by a path whose edges have distinct colors and is denoted by . The rainbow vertex connection number can be applied to graphs resulting from operations. One of the methods to create a new graph is to perform operations b...
Delivery of goods is one of the services used in the online buying and selling process at the Post Office company. Companies need a performance in the distribution of goods that is more time-consuming and cost-efficient, so it requires determination in selecting the shortest path. Many algorithms have been used to help find the shortest path for di...
A large project requires proper scheduling to obtain the duration of development and costs incurred more optimally. Optimization is submitting the project duration efficient solution by using various alternatives that can be reviewed in terms of cost and time. Optimization problems can be solved using operating research. Selected Critical Path Meth...
An Octa-Chain graph (OCm) is a graph formed by modifying the cycle graph C8 by adding an edge connecting the midpoints in C8. The minimum number of colors used to color the vertices in a graph so that every two vertices have a rainbow path is called the rainbow vertex-connected number denoted by rvc (G). While the minimum number of colors used to c...
Bilangan terhubung pelangi didefinisikan sebagai banyaknya jumlah warna minimum yang dibutuhkan untuk membuat graf G menjadi terhubung pelangi, dengan syarat sisi yang termasuk dalam lintasan pelangi tidak boleh memiliki warna yang sama. Bilangan terhubung pelangi disimbolkan dengan rc(G). Seiring berkembangnya ilmu pengetahuan dan penelitian, maka...
Pada penelitian ini didefinisikan graf baru yang dinamakan graf ferris wheel yang dinotasikan dengan Fw_n. Graf ferris wheel dengan 2n+1 titik dan 5n sisi dihasilkan dengan menggabungkan dua buah graf yaitu graf lingkaran dan graf roda dengan menambahkan sisi sebanyak 2n. Tujuan dari penelitian ini adalah menentukan bilangan terhubung pelangi pada...
Rainbow vertex-connection number is the minimum k-coloring on the vertex graph G and is denoted by rvc(G). Besides, the rainbow-vertex connection number can be applied to some special graphs, such as prism graph and path graph. Graph operation is a method used to create a new graph by combining two graphs. Therefore, this research uses corona produ...
Suatu graf dikatakan terhubung pelangi jika terdapat lintasan antara dua titik yang setiap sisi-sisinya memiliki warna berbeda. Misalkan terdapat suatu graf G tak trivial dengan definisi warna c:E(G)->{1,2,3,...}, maka bilangan terhubung pelangi dari graf G yaitu minimum k dari pewarnaan-k pelangi yang digunakan untuk mewarnai graf G dan dinotasika...
In the era of sustainable development, education is a fundamental right for everyone. Education is a process of helping humans develop themselves so that they can face all problems with an open attitude. One way to help students clarify the concepts and understanding of mathematics that is being studied during the learning process is by using teach...
This research deals with applying the Dijkstra algorithm and Welch-Powell algorithm to on-campus bus transportation problems. This research aims to determine the optimal solution of campus bus transportation routes in the shortest routes and schedules. In determining the fastest way, each intersection represented as a node, and the path described a...
Teori graf merupakan ilmu matematika yang banyak terapannya salah satunya penjadwalan. Permasalahan yang terjadi pada penjadwalan pengangkutan sampah di Kota Gorontalo berhubungan dengan pengalokasian angkutan dan tenaga kerja ke lokasi serta mengurutkan waktu pengoperasian tenaga kerja. Permasalahannya adalah jalur layanan pengangkutan sampah tida...
Suppose there is a simple, and finite graph G = (V, E). The coloring of vertices c is denoted by c: E(G) → {1,2, ..., k} with k is the number of rainbow colors on graph G. A graph is said to be rainbow connected if every pair of points x and y has a rainbow path. A path is said to be a rainbow if there are not two edges that have the same color in...
