Abstract

Children under five age is a group that susceptible to health problems such as lack of energy and protein nutrition, so this age group should get special attentions. One of the problems that should get an attention is problems nutritional status of children. Nutritional status of children is one of the indicators the level of social welfare. The classification of children?s nutritional status was conducted by nutritionist, but the problem is the scattering of nutritionist in Palu is very limited, especially in areas which far away from the city center. This case of study will be taken from Pantoloan Boya village. The limited of nutritionist was being the problems in detecting the indication of malnutrition. Through this research will be made an implementation based of computer system that has a same understanding as a nutritionist who is able to determine the nutritional status of children. One method that can be used in solving the classification of the nutritional status of children is K-Nearest Neighbor (KNN) method. K-Nearest Neighbor (KNN) is one method that use the learning algorithm where the result from the new testing sample is classified based on the majority of KNN?s category. In this research, the system classified the children according to their nutritional status based on data that obtained from the place of research. These results using k = 1 as the number of nearest neighbors which labels the majority of the k nearest neighbors are used to predict the unknown nutritional status of new data. This is because for k = 1 has better accuracy results than other values ??of k is equal to 81.67%.

Abstract

Kota Palu memiliki tingkat resiko tinggi terhadap ancaman gempa bumi dan tsunami karena terletak dalam Sabuk Gempa Pasifik dan bentangan sesar Palu Koro. Kriteria InaTews waktu yang tersedia untuk evakuasi setelah peringatan dini tsunami berbunyi adalah 15 menit. Evakuasi penduduk dari pesisir pantai kota Palu ke tempat aman merupakan tindakan yang harus dan segera dilakukan sebagai langkah penyelamatan bila terjadi tsunami. Informasi tentang tempat, jalur terpendek, dan waktu tempuh minimum untuk evakuasi memainkan peranan yang sangat penting dalam keselamatan penduduk yang akan dievakuasi. Pada penelitian ini telah dihasilkan sebuah perangkat lunak Sistem Evakuasi Tsunami untuk kota Palu (SET-KP) berbasis jalur terpendek dan waktu evakuasi minimum. Penentuan jalur terpendek dalam SET-KP menggunakan algoritma Dijkstra dan menghitung waktu evakuasi minimumnya menggunakan model matematika . Skenario evakuasi penduduk di semua cluster pesisir kota Palu menggunakan perangkat lunak SET-KP diperoleh bahwa cluster dengan jumlah penduduk cukup banyak waktu evakuasinya melebihi ketentuan InaTews. Sementara itu, cluster dengan jumlah penduduk sedikit ketentuan InaTews dapat dipenuhi, seperti cluster C70, C76 dan C79. Oleh karena itu, shelter (titik evakuasi) yang telah didefinitifkan sebelumnya dalam dokumen BPBD perlu direposisi untuk memenuhi ketentuan InaTews.

Abstract

An  edge anti-magic total labelling, -EAMT, on graph  with  vertices and  edges is bijektion , which has a set of edge weights  with  and . A  super edge anti-magic total labelling , -SEAMT, if the vertex set of  obtain the smallest labels . An -EAMT (SEAMT) labelling  is called EMT (SEMT) labelling if  and . Furthermore,  is called the magic constant. A graph  is said EMT, SEMT, -EAMT and -SEAMT if there is EMT, SEMT, -EAMT and -SEAMT labelling on graph , respectively. In this paper, we showed that the union of caterpillars and complete bipartite graph are SEAMT and SEMT, especialy for  has (-SEAMT and -SEAMT with ; graph  has -SEAMT and -SEAMT for ; and graph  has -SEAMT and -SEAMT with       where  and  for . Thus, graph  is SEMT with  for ; graph  also SEMT with  for ; as well graph  is SEMT with  for .

Abstract

Upaya pemeliharaan atau perbaikan listrik di Kota Palu mengakibatkan dilakukannya pemadaman listrik secara bergilir. Proses pemadaman tersebut selama itu tidak dilakukan secara teratur, sehingga mengakibatkan banyaknya keluhan dari pelanggan dan dapat memicu terjadinya kebakaran. Oleh karena itu, dibutuhkan suatu sistem informasi yang dapat menginformasikan jadwal pemadaman listrik menggunakan suatu alat komunikasi seperti SMS Gateway. SMS Gateway adalah sebuah perangkat lunak yang menggunakan bantuan komputer dan memanfaatkan teknologi seluler yang diintegrasikan guna mendistribusikan pesan-pesan yang di generate lewat sistem informasi menggunakan media SMS yang ditangani oleh operator seluler. Penelitian ini menjelaskan proses perancangan aplikasi SMS Gateway yang dibuat dengan teknologi SMS sehingga membantu bidang pelayanan pengiriman informasi pemadaman listrik. Software opensource yang digunakan untuk membuat pengiriman pesan pemadaman listrik berbasis SMS Gateway adalah Gammu, MySql, Apache, dan Netbeans IDE 7.4. Software NetBeans IDE 7.4 digunakan untuk membuat program SMS Gateway sehingga pengguna listrik bisa menerima informasi pemadaman listrik melalui SMS.

Abstract

An edge-magic total (EMT) labeling on a graph G(V,E) with the vertex set V and the edge set E, where |V| = p and |E| = q, is a bijective function ?: V E {1, 2, 3, ..., p + q} with the property that for each edge (xy) of G, ?(x) + ?(xy) + ?(y) = k, for a fixed positive integer k. The labeling ? is called a super edge magic total (SEMT) if it has the property that for each vertex obtain the smallest label, (V) = {1, 2, ..., p}. A graph G(V,E) is called EMT (SEMT) if there exists an EMT (SEMT) labeling on G. Study on SEMT labeling for the union of stars and paths initiated by Figueroa-Centeno et al. [2] with graph form . Furthermore, an investigation will be conducted on SEMT labeling of double stars and path, that are 2 ; 2 ;    2  and 2 . We obtain that the graphs presented above are SEMT with the magic constants k = , , and , respectively
