<![CDATA[Madrasah students' mathematical connection skills need to be of particular concern in the process of learning mathematics. Connection skills are the base for students to connect concepts in mathematics, mathematical concepts with other science concepts and mathematical concepts with everyday life. One of the efforts made in overcoming this problem is to use e-learning. Descriptive quantitative research methods are used to see how effective e-learning is for students' mathematical connection abilities. A total of 30 students were selected as research samples for data collection. Data processing techniques were divided into control groups and subsequent experiments were analyzed using descriptive statistics. The results showed that the effectiveness of technology-based e-learning included moderate criteria with an ING score of 0.56, whereas the study group without e-learning included moderate criteria with an ING value of 0.29. In conclusion, there is an increase in student learning outcomes after using e-learning media. t-test was obtained > with 0.007 <?

<![CDATA[Graf yang memiliki sifat self-similar telah terbukti memiliki representasi presisi dan akurat terhadap struktur dunia nyata. Struktur tersebut meliputi koneksi jaringan, enkripsi, rima puisi, algoritma pencarian, dan sebagainya. Sering kali sifat-sifat suatu graf dapat dilihat dan ditentukan dengan cara memecah atau mendekomposisi graf tersebut ke dalam bagian-bagian yang lebih kecil yang mengkonstruksi graf tersebut. Kita dapat memeriksa graf konstriktor tersebut untuk mendapatkan sifat-sifat graf yang disusunnya. Pada tahun 2014 penulis mendefinisikan graf flake sebagai graf yang disusun dari operasi berurutan dan bertalian dari graf komplit yang mana, dengan suatu algoritma embedding tertentu, bentuk geometri yang dihasilkan berbentuk serpih (flake) salju. Masalah umum yang melatarbelakangi pelabelan radio telah dikenal luas sebagai solusi untuk masalah penetapan saluran radio (atau sebarang koneksi nirkabel). Tujuannya adalah untuk menetapkan saluran radio sedemikian sehingga tidak ada gangguan frekuensi antar pemancar radio yang dekat secara geografis dan memiliki jangkuan dan frekuensi yang berbeda-beda. Artikel ini membahas radius, diameter, dan bilangan radio dari graf flake.]]>

<![CDATA[The total graph of a ring R, denoted as T(Γ(R)), is defined to be a graph with vertex set V(T(Γ(R)))=R and two distinct vertices u,v∈V(T(Γ(R))) are adjacent if and only if u+v∈Z(R), where Z(R) is the zero divisor of R. The Cartesian product of two graphs G and H is a graph with the vertex set V(G×H)=V(G)×V(H) and two distinct vertices (u_1,v_1 ) and (u_2,v_2 ) are adjacent if and only if: 1) u_1=u_2 and v_1 v_2∈H; or 2) v_1=v_2 and u_1 u_2∈E(G). An isomorphism of graphs G dan H is a bijection ϕ:V(G)→V(H) such that u,v∈V(G) are adjacent if and only if f(u),f(v)∈V(H) are adjacent. This paper proved that T(Γ(Z_2p )) and P_2×K_p are isomorphic for every odd prime p.]]>

<![CDATA[Traveling is one of the needs of everyone to relax the mind from the busyness that is lived every day. One of the cities in East Java which is a prima donna for traveling is Malang. The city has approximately 43 tourist destinations. Usually, tourists who want to visit not only one place, but several places. generate assistance in deciding which destinations to visit first in order for their trip to be effective. The shortest search process in this study uses the A-Star Algorithm, one of the BFS algorithms which in the process really considers the heuristic value. The process of testing the shortest route is done by selecting a starting point, then selecting several tourist locations. Next, the shortest route will be searched using the A-star algorithm at each destination, then which destination will be visited first. And so on until the final destination. The effectiveness of the route which involves comparison with the route presented by google maps. Based on the results of 30 experiments on several comprehensive destinations, it was found that the average route search using the A-Star algorithm was 44.17% shorter than that presented on google maps. This is due to the uniqueness of the algorithm in which there is a heuristic value and selection for each destination so as to make the route more effective.]]>

<![CDATA[Pada penelitian ini dibahas penerapan tanda tangan digital sebagai bentuk penjagaan keontentikan suatu dokumen elektronik yang dibuat dengan menggabungkan dua algoritma, yaitu fungsi hash MD5 (Message Digest 5) dan RSA (Rivest Shamir Adleman). Isi dokumen elektronik diberikan fungsi hash MD5 sehingga menghasilkan message digest. Selanjutnya message digest akan dienkripsikan menggunakan algoritma kriptografi RSA sehingga menghasilkan tanda tangan digital. Hasil pengujian menunjukkan bahwa tanda tangan digital yang dihasilkan adalah berbeda-beda dari setiap dokumen elektronik. Dokumen elektronik yang menghasilkan nilai dekripsi tanda tangan digital dan message digest modulo yang sama menunjukkan bahwa dokumen elektronik tidak mengalami perubahan pada isinya. Sebaliknya, dokumen elektronik yang tidak menghasilkan nilai dekripsi dan tanda tangan digital dan message digest modulo yang sama menunjukkan bahwa dokumen elektronik telah mengalami perubahan pada isinya.]]>

<![CDATA[A vertex coloring of a graph , is an assigments of colors to the vertices of , such that no two adjacent vertices are assigned the same color. The least number of colors needed for an vertices coloring of a graph is the chromatic number, denoted by . A graph is said to be planar if it can be drawn in the plane so that no edges crossing except at endpoints. A dual graph is constructed from the planar graph. Each region in planar graph can be represented by a vertex of the dual graph. Two vertices are connected if the region represented by these vertices are neugbours and have a common border. A diamond graph denoted by , can be used to model structure networks. In this study, it is shown that the chromatic number of dual diamond graph is χ(〖Br_n〗^* )={█(3,n=2 and n≥4@4,n=3.)┤]]>

<![CDATA[PT Citra Akes Indonusa is a company that operates on the expertise of information technology services in Banten Province. One of the services provided by the company requires the construction of a Base Transceiver Station (BTS) tower. The tower requires maintenance if there is damage to the network signal. As a result, the shortest route is needed to make it easier for employees to reach the tower location to be more effective. There are eight BTS tower locations in Tangerang Regency and three BTS tower locations in Tangerang City. The process of finding the shortest route in this study uses the Floyd Warshall algorithm, which is unique in finding the shortest route by comparing each edge of all edges that are passed. The process of testing the shortest route is done by selecting the starting point, then selecting several BTS tower locations. Next, the shortest route will be searched using the Floyd Warshall algorithm from each point of destination for the BTS tower location, then the BTS tower location will be selected first and so on until the last destination. The effectiveness of this shortest route search involves a comparison of the routes presented by Google Maps. Based on the results of 30 randomized trials on BTS tower locations, the average shortest route effectiveness was 25.54% compared to the route generated by Google Maps. This is due to the selection at each BTS tower destination location so as to make the route more effective.]]>
