Abstract

ABSTRACTDengue Hemorrhagic Fever (DHF) is a disease whose main cause is the flaviviridae virus. This virus can be transmitted through mosquito bites. The spread of this disease is faster in urban areas than in rural areas due to the high population density. Aedes aegypti mosquito is very easy to spread dengue virus from one person to another because it has a domestic nature. The Ministry of Health has collaborated with local health centers in the DHF prevention program. Ngemplak Simongan Health Center is one of the public health centers located in the District of West Semarang that serves a variety of treatments for this type of disease, one of which is a patient with Dengue Hemorrhagic Fever (DHF). C4.5 algorithm is used to predict dengue fever which aims to produce a decision tree. The choice of using Algortima is because it is widely used to describe a pattern / knowledge / information in the form of a decision tree explicitly. Application created using PHP programming language that produces prediction of dengue fever. The test results obtained an accuracy value of 94.44% so that the application program built can be used correctly.Keywords: c4.5 algorithm, decision tree , dengue hemorrhagic feverABSTRAKDemam Berdarah Dengue (DBD) adalah sebuah penyakit yang penyebab utamanya adalah virus flaviviridae. Virus ini dapat ditularkan melalui gigitan nyamuk. Penyebaran penyakit ini lebih cepat di area perkotaan dibandingkan di area pedesaan karena faktor tingginya kepadatan penduduk. Nyamuk Aedes aegypti sangat mudah menyebarkan virus dengue dari orang satu ke orang lain karena memiliki sifat domestik. Departemen kesehatan telah melakukan kerja sama dengan puskesmas sekitar dalam program penanggulangan penyakit DBD. Puskesmas Ngemplak Simongan merupakan salah satu puskemas yang berada di Kecamatan Semarang Barat yang melayani berbagai macam pengobatan jenis penyakit, salah satunya adalah penderita Demam Berdarah Dengue (DBD). Algoritma C4.5 digunakan untuk prediksi penyakit demam berdarah yang bertujuan menghasilkan sebuah pohon keputusan. Pemilihan penggunaan Algortima ini karena banyak digunakan untuk menggambarkan suatu pola/pengetahuan/informasi dalam bentuk pohon keputusan secara eksplisit. Aplikasi yang dibuat menggunakan bahasa pemrograman PHP yang menghasilkan prediksi penyakit demam berdarah. Hasil pengujian didapatkan nilai akurasi sebesar 94.44% sehingga aplikasi program yang dibangun dapat digunakan secara benar.Kata Kunci: algoritma c4.5, pohon keputusan, demam berdarah dengue

Abstract

AbstrakPemberian beasiswa kepada siswa Sekolah Menengah Atas (SMA) sudah umum dilakukan. Hal ini terjadi sejak adanya dana pendidikan 20% dari Kementrian Pendidikan dan Kebudayaan (Kemendikbud). Selain untuk batuan kepada siswa yang kurang mampu, beasiswa juga diberikan kepada siswa yang mempunyai prestasi akademik maupun prestasi non akademik. Pemberian beasiswa yang terjadi selama ini baik di SMA ataupun yang lain masih menggunakan perhitungan dan pengolahan data secara manual. Proses perhitungan secara manual memungkinkan adanya penerima  beasiswa  yang tidak tepat sasaran. Pengolahan penerimaan beasiswa bisa menggunakan sebuah algoritma data mining untuk mengklasifikasikan  calon penerima  beasiswa  berdasarkan  data yang diambil dari data siswa  penerima beasiswa sebelumnya (data training) dengan data yang diambil dari calon penerima beasiswa (data testing). Penelitian ini bertujuan membantu proses seleksi beasiswa di SMA menggunakan algoritma K-Nearest Neighbor (KNN) supaya penerima beasiswa tepat sasaran. Algoritma KNN bisa memberikan  kebutuhan data yang akurat  dan informasi yang diperlukan untuk menyeleksi  calon penerima beasiswa. Hasil dari penelitian ini adalah adalah terseleksinya 30 orang dari 89 data yang telah dilakukan klasifikasi.  Pengujian sistem menggunakan pengujian akurasi metode confusion matrix dengan hasil pengujian sebesar 90.5%. Hal ini menunjukkan bahwa algoritma KNN bisa digunakan untuk mengklasifikasikan seleksi penerimaan beasiswa.Kata Kunci: algoritma, beasiswa, data mining, KNNAbstractProviding scholarships to high school students (SMA) is common. This happened since there was a 20% education fund from the Ministry of Education and Culture (Kemendikbud). In addition to rocks to underprivileged students, scholarships are also given to students who have academic and non-academic achievements. Scholarships that have occurred so far both in high school and others still use manual calculation and data processing. The manual calculation process allows for scholarship recipients who are not on target. Processing scholarship receipts can use a data mining algorithm to classify prospective scholarship recipients based on data taken from previous scholarship recipient student data (training data) with data taken from prospective scholarship recipients (data testing). This study aims to help the scholarship selection process in high school using the K-Nearest Neighbor (KNN) algorithm so that scholarship recipients are on target. The KNN algorithm can provide accurate data and information needed to select prospective scholarship recipients. The result of this research is the selection of 30 people from 89 data that has been classified. System testing uses the accuracy of confusion matrix testing with 90.5% test results. This shows that the KNN algorithm can be used to classify scholarship acceptance selections.Keywords: algorithms, data mining, KNN, scholarship

Abstract

This research was conducted with the aim of helping decide the destination country for overseas exhibitions at the Batik Hatta Boutique. By knowing all the data and information of a country, boutique owners can decide which country to visit in the batik exhibition. Because if you attend the cast in all countries, there will be overruns in costs. The methods used are AHP and MAUT. The AHP method is used as a weighting using a linguistic value scale. Weights are obtained from the pairwise comparison matrix between two elements of all elements that occur at the same hierarchical level. The MAUT method is used to determine the importance of each alternative for the ranking process. The results of this study indicate that Cambodia was chosen as the location to be visited for the batik exhibition. The results of the validation using the Spearman Rank correlation comparison obtained a value of 0.951 meaning that this method can be used as a decision making.
