Abstract

Document summarization is needed to get the information effectively and efficiently. One method used to obtain the document summarization by applying machine learning techniques. This paper proposes the application of regression models to query-focused multi-document summarization based on the significance of the sentence position. The method used is the Support Vector Regression (SVR) which estimates the weight of the sentence on a set of documents to be made as a summary based on sentence feature which has been defined previously. A series of evaluations performed on a data set of DUC 2005. From the test results obtained summary which has an average precision and recall values of 0.0580 and 0.0590 for measurements using ROUGE-2, ROUGE 0.0997 and 0.1019 for measurements using the proposed regression-SU4. Model can perform measurements of the significance of the position of the sentence in the document well.

Abstract

Virus komputer merupakan suatu program yang menginfeksi komputer terutama pada saat komputer sedang beroperasi dan menjadi momok bagi pengguna komputer. Virus komputer dapat menggandakan dirinya sendiri dan menyebar dengan cara menyisipkan dirinya pada program dan data lainnya. Efek negatif virus komputer adalah memperbanyak dirinya sendiri, yang membuat sumber daya pada komputer terutama penggunaan memori menjadi berkurang secara signifikan. Diperlukan suatu penangkal atau antivirus dalam mencegah penyebaran yang lebih jauh dalam sistem komputer. Pada penelitian ini, dilakukan suatu identifikasi virus dengan menggabungkan dua metode yaitu Naïve Bayes Classifier dengan Neural Network. Fitur virus didapatkan dari mengkodekan ciri-ciri dari virus. Untuk klasifikasi awal digunakan metode Naïve Bayes Classifier untuk membagi dua jenis fitur, yaitu virus dan bukan virus. Setelah masuk kedalam jenis virus, maka diklasifikasikan kedalam dua jenis virus yaitu trojan atau worm menggunakan salah satu metode neural network (perceptron). Hasil sistem setelah dilakukan uji coba didapatkan recognition rate tertinggi yaitu sebesar 94.12%.

Abstract

This research uses a case study at PT Fajar Mas Murni Surabaya which aims to classify item of spare parts inventory with a BCG matrix approach to determine sales strategy of spare part inventory. The classification results with BCG matrix obtained 6,60% items included in quadrant stars which contributed 80,67% turnover for the company; 15,57% items included in the question marks quadrant which contributed 14,95% turnover for the company; 71,70% items included in the quadrant dogs which contributed only 1,87% turnover for the company; and 6,13% is included in the cash cows quadrant which contributes a 2,50% turnover for the company. The strategy analysis that should be carried out (1) on the stars quadrant is to forecast the sales to maintain the continuity of spare part inventory, (2) on the question marks quadrant is to develop the sales by selling items at a discount so that can increase sales volume and can spend inventory, (3) on the dogs quadrant is to further enhance the promotion activities of these items, (4) on the cash cows quadrant is to maintain sales. Then sales forecasting is carried out on stars quadrant spare parts inventory in 2018 so that continuity is maintained by using the Trend (t) moving average ratio method with Cycle variation (C), Season variation (S), and Irregular movement (I), which obtained MAPE value of 23%. If only using Trend, it obtained greater MAPE value of 27%.

Abstract

Waiting for service is a common thing in-hospital services. The more patients are waiting, the service delay increases, so waiting time in the queue gets longer. In health care in a hospital, a patient will queue several times in more than one queue in a hospital outpatient installation. The case study in this research is the queue system in the hospital's outpatient treatment, implementing an open Jackson queueing network to minimize waiting time. The workstations examined in this study were the registration, pre-consultation, and cardiology poly consultation, and pharmacy. The data is carried out for six days, counting the number of arrivals and departures with each point at intervals of 5 minutes. Applying the Jackson open queue network model, a recommendation was obtained for the hospital to increase employees' numbers. The registration workstation must have four servers; a poly cardiology workstation had three nurses and four doctors, while for pharmacy, had seven employees. With this personnel's addition, patients' total waiting time in the queuing system is approximately 12 minutes/patient. So, it can reduce waiting times in the queueing system that was initially 108 minutes/patient.

Abstract

Pembangunan manusia kini dipandang sebagai tolak ukur keberhasilan pembangunan suatu bangsa yang berkaitan erat dengan bidang ekonomi, sosial, budaya, politik, dan lingkungan. Keberhasilan pembangunan manusia diukur berdasarkan Indeks Pembangunan Manusia (IPM). Kabupaten Bojonegoro merupakan salah satu kabupaten di Provinsi Jawa Timur yang mempunyai sumber daya alam yang beragam dan melimpah. Besarnya potensi sumber daya alam yang dimiliki seharusnya sejalan dengan kualitas pembangunan manusianya. Namun ternyata hal tersebut tidak sejalan dengan nilai IPM Kabupaten Bojonegoro yang berada di bawah rata-rata nilai IPM Jawa Timur. Sehingga pemerintah Bojonegoro terus berupaya untuk memaksimalkan potensi dan meningkatkan nilai IPM. Berdasarkan hal tersebut maka perlu dilakukan peramalan (forecasting) sebagai acuan untuk memaksimalkan tingkat pembangunan manusia di Kabupaten Bojonegoro pada beberapa tahun yang akan datang. Pada penelitian ini, untuk meramalkan IPM di Kabupaten Bojonegoro menggunakan metode Double Exponential Smoothing (DES) dari Brown dengan data yang digunakan merupakan data IPM di Kabupaten Bojonegoro dari tahun 2010 sampai 2020. Data yang digunakan diperoleh dari Badan Perencanaan Pembangunan Daerah (Bappeda) dan Badan Pusat Statistik (BPS) Kabupaten Bojonegoro. Berdasarkan hasil perhitungan, peramalan terbaik diperoleh berdasarkan nilai parameter α 0.7 dengan besar nilai MAPE 0.376% yang masuk kriteria sangat baik. Hasil peramalan IPM untuk tahun 2021 sebesar 69.61, untuk tahun 2022 sebesar 70.14, dan untuk tahun 2023 sebesar 70.67 termasuk kategori IPM sedang. Kata kunci: Double exponential smoothing brown, Indeks Pembangunan Manusia (IPM), peramalan

Abstract

The role of technology in an institution is beneficial for any activities, especially in managing documents administration, which is now most of the company used digital archive systems. That's because the manual archive system is considered less effective and efficient, where it takes a lot of space and time to search for document archives. Microsoft Access is a windows-based database processing program with Visual Basic for Application (VBA), commonly used to create a windows-based application. The purpose of this paper is to make an administration letter and archives system based on Microsoft Access. The results of this design have passed the trial process for approximately two weeks and received a positive response. The system design can be run well, and its functions correctly without errors. So it can help the secretary or other employees to manage all documents (letters and archives) more accessible and faster.
