Abstract

Dalam sebuah perusahan untuk menunjang salah satu aktifitas maka di perlukan kendaraan operasional, begitu juga di PT. Batik Semar Surakarta yang menyediakan beberapa kendaraan operasional yang berupa mobil niaga atau mobil box dan mobil konvensional atau mobil penumpang. Dengan adanya kendaraan operasional maka harus ada sebuah perawatan agar layak dan aman saat dipakai dan tidak terjadi hal hal yang diingikan saat di pakai, maka diperlukan sebuah sistem informasi berbasis web untuk memonitoring semua kendaraan yang bisa melihat semua history dari kendaraan tersebut , mulai dari pengecekan kendaraan, pemakaian kendaraan, serta perbaikan kendaraan. Untuk memperoleh data-data yang diperlukan selama penelitian, penulis menggunakan beberapa metode, antara lain: wawancara, observasi dan studi pustaka. Data yang diperoleh kemudian dianalisis dan digambarkan dengan menggunakan metode DFD(Data flow Diagram). Hasil akhir dari penelitian ini adalah berupa monitoring kendaraan operasional yang dapat membantu bagian umum untuk mempermudah dalam monitoring perawatan kendaraan operasional di PT.

Abstract

Publication is an important tridharma activity for lecturers. This study aims to produce a clustering model using the K-Means algorithm which was built for ease of operation of publications. The method used is research and development which includes the stages of data collection, data preprocessing, clustering process and cluster analysis. The input data consists of 87 with 8 attributes, namely the number of journal articles indexed by Sinta, the number of journal articles indexed by Scopus, the number of citations in Scopus, the H-index in Scopus, the number of articles in indexed journals in Google Scholar, the number of citations in Google Scholar, the H-index in Google Scholar and H-index10 in Google Scholar. The K-Means algorithm is used with 3 clusters and 100 epochs. The clustering results are divided into 3 clusters, namely cluster 1 with 17 members, cluster 2 with 32 members and cluster 3 with 38 members. Clustering with 5 clusters produces cluster 1 with 5 members, cluster 2 with 12 members, cluster 3 with 20 members, cluster 4 with 18 and cluster 5 with 32 members. The results of the cluster analysis show that the clustering process with 3 clusters is improved and the academic application is better than clustering with 5 clusters.

Abstract

This study aims to produce an image processing application using Mathematical Morphology to improve the quality of the digital image for breast cancer detection. Medical image is an image produced or used in the medical field. Improving medical image quality is very useful for diagnosis and advanced image processing. Breast healthy is important for women. Breast cancer is the main killer for women. Biomedical breast image data is secondary data. The next process is the initial processing, which is processing that is related to pixel size, gray scale, and so on. The improvement of medical image in this study uses the Mathematical Morphology method which consists of Dilation, Erosion, Opening (Erosion-Dilation) and Closing (Dilation-Erosion) processes. The expected results of this research are medical digital images that have improved their quality as a result of Dilation, Erosion, opening and closing processes.

Abstract

Clinical Decision Support Systems (CDSS) are computational models designed impact clinical decision making about individual patients at the point in time that these decision are made. Clinical Decision Support Systems (CDSS) form an important area of research. While traditional systematic literature surveys focus on analyzing literature using arbitrary results, visual surveys allow for the analysis of domains by using complex network-based analytical models. In this paper, we present a detailed visual survey of CDSS literature using important papers selected. The aim of this study is to review a number of articles related to CDSS for heart and stroke diseases. In this study several articles are comparable to the computational methods and rules used for data processing. From the analysis of several sources of literature, the computational methods and rules used in CDSS are Principle Component Analysis (PCA), Support Vector Machine (SVM), Naïve Bayes data mining algorithm, Case Based Recommendation Algorithm, Weighted Fuzzy Rules, Ontology Reasoning, TOPSIS Analysis, Genetic Algorithms, Fuzzy Neural network, Case-based reasoning (CBR), Weighted Fuzzy Rules and Decision Tree.

Abstract

Games are fun playing activities. In the past, most children and adolescents played games with physical activities, but nowadays children and adolescents play games with their gadgets. Excessive gaming activity can lead to addiction. Game addiction can cause mental illness, even physical illness. This study aims to help gamers as well as the general public to better understand the symptoms of game addiction and early solutions to game addiction. This study uses forward chaining as a plot, namely by collecting symptoms to find the level of addiction and certainty factors as a calculation by calculating the level of trust and distrust of symptoms. In this study, game addiction resulted in 3 levels, low level game addiction, medium level game addiction and high level game addiction.

Abstract

Heart disease and stroke are the main contributions to health disorder. Two factors influence the susceptibility of the disease, namely clinical risk factors and non-clinical factors. This study aims to analyze the effect of non-clinical risk factors on the susceptibility to heart disease and stroke. The non-clinical risk factors are stress management, age, obesity, genetics, smoking, gender, lifestyle (nutrition), lifestyle (timing rest), and physical activity. Analysis of the influence of non-clinical risk factors on susceptibility using statistical methods, namely descriptive statistics, normalization tests with the Kolmogorov-Smirnov test, validity tests, reliability tests, and correlation tests. The descriptive statistical tests show that the risk factors for stress management, obesity, and smoking have a more significant influence than others. While Gender and physical activity have more negligible effect than others. Testing with one sample Kolmogorov-Smirnov Test shows that the data is normally distributed. Validity testing produces 100% valid data. The reliability test using Cronbach's alpha of 9 non-clinical risk factor items resulted in a value of 0.684, which means reliable. Correlation test between 9 items of non-clinical risk factor shows significant between items.

Abstract

Fashion Viral Solo merupakan salah satu distributor perlengkapan fashion di Surakarta yang belum memanfaatkan data yang dimiliki untuk melakukan segmentasi dan mengelompokkan pelanggan berdasarkan kemiripannya. Segmentasi adalah proses untuk mencari tahu karakteristik dari pelanggan berdasarkan kesamaan tertentu, sehingga memudahkan pengumpulan informasi tentang pelanggan yang memberikan profit bagi perusahaan. Segmentasi menjadi salah satu strategi untuk menghadapi persaingan usaha, untuk mempertahankan pelanggan, dan untuk membantu manajemen dalam menyusun strategi promosi untuk meningkatkan penjualan. Tujuan dari penelitian ini adalah melakukan segmentasi pelanggan yang pernah bertransaksi di Fashion Viral Solo berdasarkan karakteristiknya. Pada penelitian ini, peneliti menggunakan algoritma K-Means untuk melakukan clustering dan penerapan metode Recency, Frequency dan Monetary. K-Means adalah algoritma sederhana, mudah diimplementasikan, tidak lambat, mudah disesuaikan, dan sering digunakan dalam proses data mining khususnya clustering. Nilai atribut Recency menunjukkan waktu terakhir transaksi, Frequency menunjukkan jumlah transaksi, dan Monetary menunjukkan total nominal transaksi. Dengan menggunakan K-Means dan metode Recency, Frequency dan Monetary, peneliti dapat melakukan segmentasi pelanggan Fashion Viral Solo. Dari penelitian ini, diperoleh hasil 2 cluster pelanggan. Cluster 1 dengan jumlah anggota terbanyak, yakni 343 pelanggan dan cluster 2 dengan jumlah anggota 8 pelanggan. Untuk menentukan jumlah cluster yang paling optimal, peneliti menggunakan metode Silhouette Scores dan diperoleh hasil jika membagi pelanggan menjadi 2 cluster adalah yang paling optimal.
