Abstract

Data science merupakan gabungan ilmu komputer, statistika, dan pengetahuan domain bisnis untuk ekstraksi tumpukan data yang besar menjadi pengetahuan sehingga mendapatkan pattern atau pola-pola yang dapat memudahkan pengambil keputusan. Adapun orang menggeluti bidang data science disebut data scientist. Profesi data scientist akhir-akhir ini menjadi profesi yang sangat seksi di abad 21. Sumber daya manusia yang berprofesi sebagai data scientist di Indonesia sangat sedikit bila dibandingkan ketersedian lapangan kerja dibidang data science. Dengan kata lain, ketersediaan lapangan kerja data science berbanding terbalik dengan ketersediaan SDM yang berprofesi sebagai data scientist, dimana jumlah SDM data scientist sangat sedikit dibandingkan dengan jumlah lapangan kerja yang berlimpah. Salah satu solusi yang ditawarkan adalah mengadakan pelatihan dan workshop untuk pengenalan data science untuk meningkatkan SDM bidang data science khususnya di Universitas Bumigora. Metode pelaksanaan yang digunakan adalah penyampaian materi tentang data science dan simulasi penggunaan metode data science dalam kasus real menggunakan Google Colab. Berdasarkan hasil pelatihan dan workshop yang telah dilaksanakan, dapat meningkatkan pemahaman dan kemampuan para peserta untuk menggunakan metode-metode yang ada pada data science untuk mengolah data menjadi sebuah pengetahuan.

Abstract

The main thing in the development of education is the quality of education. One of the determinants of the quality of education is counseling guidance. The problem so far is that most students who have problems feel embarrassed in doing counseling directly to the BK teacher and usually consult with their friends so that they cannot solve the problems they face. This makes it difficult for BK teachers to deal with student problems, so we need a system that can help and solve problems experienced by students. The purpose of this study is to design an expert system that overcomes the problems suffered by students using the certainty factor method that can provide solutions based on the types of problems suffered by the students. The expert system development methodology in this study uses the waterfall methodology which consists of needs analysis, design, coding, and testing. The result of this research is in the form of an expert system application for counseling problem students who apply a web-based certainty factor method that can make it easier for students to find out the types of problems they face based on the problems symptoms entered. This study concludes that the expert system application that was built has a good level of convenience based on the results of usability testing using the SUS (System Usability Scale) method of 76.5%.

Abstract

SMK 2 Negeri Mataram merupakan lembaga pedidikan yang terteletak dikota mataram. Setiap tahunnya pihak SMK Negeri 2 Mataram (pihak humas) melakukan seleksi beasiswa bagi siswa yang memiliki nilai akademik bagus tetapi tidak mampu secara ekonomi. Selama ini permasalahan yang dihadapi oleh pihak pengambil keputusan atau humas SMK Negeri 2 Mataram dalam seleksi penerima beasiswa adalah waktu yang dibutuhkan sangat lama karena dilakukan secara manual. Karena pihak humas SMK Negeri 2 mataram memilih siswa yang berhak mendapatkan bantuan beasiswa dengan cara verifikasi manual. Cara ini tentunya akan menyebabkan banyak terjadinya salah sasaran dalam pembagiannya, dimana yang dianggap mampu, bisa mendapatkan beasiswa tersebut, sedangkan yang dianggap tidak mampu tidak mendapatkannya. Tidak hanya itu, pihak humas juga kesulitan dalam penentuan penerima beasiswa dikarenakan antar calon penerima memiliki kesamaan nilai setiap kriteria yang digunakan. Adapun kriteria yang digunakan dalam seleksi penerima beasiswa adalah nilai rata-rata, penghasilan orang tua, tanggungan orang tua, jarak tempat tinggal, dan kehadiran. solusi yang ditawarkan pada penelitian ini adalah menggunakan konsep sistem pendukung keputusan dengan kombinasi metode AHP dan TOPSIS untuk seleksi penerima beasiswanya. Metode AHP digunakan untuk pembobotan secara otomatis dan mendapatkan bobot prioritas antar kriteria yang digunakan, untuk minimalisir terjadinya pembobotan secara subyektif. Sedangkan metode TOPSIS digunakan untuk melakukan perangkingan penerima beasiswa dengan cara mengoptimalkan solusi ideal positif dan solusi ideal negatif untuk mendapatkan penerima beasiswa yang tepat dan layak. Tahapan-tahapan dalam pengembangan sistem pendukung keputusan seleksi penerima beasiswa adalah pengumpulan data, perancangan model MADM untuk melihat hubungan antar kriteria dengan alternatifnya, Coding menggunakan Bahasa pemrograman PHP dan Mysql. Tahapan terakhir adalah Pengujian untuk validasi hasilnya dengan perhitungan manual dan sistem. Hasil penelitian yang didapatkan adalah kombinasi metode AHP-TOPSIS mampu dimplementasikan untuk mendapatkan alternatif terbaik sebagai penerima beasiswa. Adapun kesimpulan penelitian ini adalah dengan adanya sistem pendukung keputusan rekomendasi penerima beasiswa tersebut dapat memudahkan dan mempercepat pihak pengambil keputusan (pihak humas) dalam seleksi penerima beasiswa dengan transparan dan okjektif.

Abstract

During the thesis writing process, the role of the supervisor is needed so that the completion of the thesis is timely so that the quality of the thesis is maintained. One of the problems in determining the thesis supervisor for undergraduate computer science at Bumigora University is the subjectivity of the head of the study program in determining the thesis supervisor. Not only that, the selection process for supervisors is done manually so that it can take a long time and can slow down student thesis work.  Students' thesis work will be late and not on time if the thesis topic is not in accordance with the competence of the lecturer. This study aims to apply the cosine similarity method to the recommendation of a thesis supervisor for undergraduate computer science at Bumigora University. The stages of this research consist of collecting thesis documents, pre-processing text (Case Folding, Tokenization, Filtering, Stemming), word weighting with TF-IDF, implementation of the cosine similarity method, and accuracy testing. The data used are 113 thesis documents which are divided as training data as many as 90 documents and testing data 23 documents. Based on the testing data on the test, the cosine similarity method can correctly recommend 21 of 23 thesis documents with an accuracy of 91.3%. Thus, the cosine similarity method can be applied to the case of selecting a thesis supervisor for undergraduate computer science at Bumigora University because it has very good accuracy.

Abstract

The use of electricity has become a need that is increasing day by day. So it is not surprising that the problem of using electricity has attracted the attention of many researchers to research it. Electricity users make various efforts and ways to save on the use of electrical energy. One of them is saving electricity usage by electricity users using electrical energy-efficient equipment. That is why the previous research confirms the need for interventions to reduce the use of electrical energy. Therefore, this study aims to predict electricity use and measure the performance of the anticipated results of electricity use. This study uses the back-propagation method in predicting the use of electricity. This study concluded that the backpropagation architectural model with better performance is the six hidden layer architecture, 0.4 learning rate, and the Root Means Square Error (RMSE) value of 0.203424. Meanwhile, the training data test results get the best architectural model on hidden layer 8 with a learning rate of 0.3 with an RMSE performance value of 0.035811. The prediction results show that the prediction of electricity consumption is close to the actual data of actual electricity consumption.

Abstract

Health is something that is important for everyone, from year to year various efforts have been developed to get better and quality health. Good nutritional status for toddlers will contribute to their health and also the growth and development of toddlers. Fulfillment of nutrition in children under five years old (toddlers) is a factor that needs to be considered in maintaining health, because toddlerhood is a period of development that is vulnerable to nutritional problems. There are more than 100 toddler data registered at the Integrated Healthcare Center in Peresak Village, Narmada District, West Lombok Regency. The book contains data on toddlers along with the results of weighing which is carried out every month. However, to classify the nutritional status of toddlers, they are still going through the process of recording in a notebook by recording the measurement results and then looking at the reference table to determine their nutritional status. This method is still conventional or manual so it takes a long time to determine the nutritional status. Therefore, the solution in this study is to develop a web-based application for the classification of the nutritional status of children under five using the C4.5 method. The stages of this research consisted of problem analysis, collection of 197 instances of nutritional status datasets obtained from Integrated Healthcare Center Presak, analysis of system requirements, use case design, implementation using the C4.5 method, and performance testing based on accuracy, sensitivity, and specificity. The results of this study are a website-based application for the classification of the nutritional status of children under five using the C4.5 method. The performance of the C4.5 method in the classification of the nutritional status of toddlers using testing data as much as 20% gets an accuracy of 95%, sensitivity of 100%, and specificity of 66.6%. Thus, the C4.5 method can be used to classify the nutritional status of children under five, because it has a very good performance.

Abstract

Most of the health data contained unbalanced data that affected the performance of the classification method. Unbalanced data causes the classification method to classify the majority data more and ignore the minority class. One of the health data that has unbalanced data is Pima Indian Diabetes. Diabetes is a deadly disease caused by the body's inability to produce enough insulin. Complications of diabetes can cause heart attacks and strokes. Early diagnosis of diabetes is needed to minimize the occurrence of more severe complications. In the diabetes dataset used, there is an imbalanced data between positive and negative diabetes classes. Diabetes negative class data (500 data) is more than diabetes positive class (268), so it can affect the performance of the classification method. Therefore, this study aims to apply the Smote-Tomeklink and Random Forest methods in the classification of diabetes. The research methodology used is the collection of diabetes data obtained from Kaggle, as many as 768 data with eight input attributes and 1 output attribute as a class, pre-processing data is used to balance the dataset with Smote-Tomeklink, classification using the random forest method, and performance evaluation based on accuracy, sensitivity, precision, and F1-score. Based on the tests conducted by dividing data using 10-fold cross-validation, the Random Forest algorithm with Smote-TomekLink gets the highest accuracy, sensitivity, precision, and F1-score compared to Random Forest with Smote. The Random Forest algorithm with Smote-Tomeklink has 86.4% accuracy, 88.2% sensitivity, 82.3% precision, and 85.1% F1-score. Thus, using Smote-Tomeklink can improve the performance of the random forest method based on accuracy, sensitivity, precision, and F1-score.
