Abstract

Long-term load forecasting is intended to estimate the electrical load on an annual time period. It has an important role in the real control and security functions of an energy management system. This study is focused on designing long-term load forecasting in Palu electrical systems by using mamdani fuzzy logic method. The process of long term load forecasting is done by providings inputs; the number of customers, PDRB, and the power used for residences, businesses and public load at the previous year into the fuzzy logic system so that it is produced an output: the power used for the next year. The shows that mamdani fuzzy logic provide high level accuracy of forecasting and very small value of MSE.Index Terms:- fuzzy logic, MSE value, number of consumers, PDRB, the power used

Abstract

Production in the restaurant is a continuous production that must be provided with uncertain request based on the consumer demand. Availability of raw materials is preferred to support the production process. In purchasing management it is often difficult to choose the right supplier of raw materials for each process order. The purpose of this research is to implement the method of Fuzzy Analytical Hierarchy Process (FAHP) in the Decision Support System (DSS) purchase of raw materials to suppliers. The addition of fuzzy logic in AHP is used to enhance the accuracy of subjectivity in the process of purchasing management assessment for each criteria and alternatives.The analysis includes a comparison with the results of manual calculations based SPK FAHP and accuracy of the final system with expert recommendations for the management of the purchase order process of DSS.The results showed an increase in profit of the accuracy of the selection of suppliers restaurant using FAHP method compared with the manual method. The analysis shows a significant difference when applied to the same material, fixed price of each supplier but different number of purchases, able to provide the difference in price which means lower costs and increase profits purchase.Index Terms — DSS, FAHP, Supplier Management, Order Management, Raw Material, FAHP.

Abstract

Citra dijital kulit kayu tanaman karet memiliki tingkat kerapatan intensitas yang tinggi. Pola suatu citra dapat dikenali melalui proses analisis ciri. Ekstraksi ciri yang merupakan salah satu proses analisis ciri pada penelitian ini mengunakan metode Virtual Center Of Gravity (VCG) dengan segmentasi citra berbasis warna abu-abu (Gray Base) dan warna hitam putih (Contour Base). Prototype ciri yang dibangun berasal dari 3 (tiga) data citra yang telah melalui proses pemilihan data terbaik (best sample selection) sebagai proses pelatihan dengan menggunakan tenik coefficient correlation. Keputusan yang diharapkan adalah sebuah model klasifikasi usia produktifitas tanaman karet dengan menguji berbagai data citra uji terhadap prototype ciri dengan menggunakan pengukuran kemiripan dan jarak (similiarity measurement). Performance dari pengujian ini menggunakan pengukuran tingkat kesalahan (error analysis rate) dan pengukuran keberhasilan penentuan klasifikasi (Accuracy). Hasil penelitian ini menunjukkan bahwa dari maksimal 18 data pengujian yang terbagi menjadi maksimal 6 data valid image dan 12 data forgery image, dengan variasi pengujian sebanyak 5 kali pada setiap kategori diperoleh tingkat Accuracy terendah sebesar 77.78% dan tertinggi sebesar 85.19%.Kata Kunci — Performance, Prototype ciri, Segmentation Gray Base & Contour Base, Similarity measurement, Virtual Center of Grafity.

Abstract

Beberapa lapisan dari Sistem Informasi Geografis (SIG) bisa dibedakan oleh mata telanjang dari sebuah citra satelit namun pasti akan melelahkan jika mengamati citra begitu banyak. Penelitian ini dilakukan untuk melakukan otomasi pengamatan dengan metode segmentasi. Metode segmentasi yang diusulkan adalah Hybrid Fuzzy C-Means – Particle Swarm Optimization (FCM-PSO). Hasil penelitian menunjukkan FCM-PSO lebih unggul dari FCM biasa sekalipun dengan kelemahan waktu eksekusi yang lebih panjang.Kata Kunci—FCM, PSO, Segmentasi, SIG

Abstract

Heart disease is a deadly disease in the world. Some countries that have a high risk of death are America, Australia and England. It is difficult for a person do a medical checkup not only because of the financial matter but also because they don't care about it. This study is to help people on early diagnose to the risk of heart disease. Expert System is used as the basis of this study which is using Bayesian Network algorithms with datasets from previous studies conducted in Europe. The objective of this research are (1) to design knowledge base, inference engine with Bayesian network for early diagnose of heart diseases, (2) to develop web-based system that help people to get early diagnose of risk heart disease. This study was conducted by the help of a heart disease specialist and internist that helps validate the dataset and the results of research through application testing detection of heart disease risk. This result is consistent with the analysis that can be used by physicians and public.Index Terms—expert system, Bayesian network, heart disease, early diagnose.

Abstract

The main problem in the application of the sound source detection is to estimate the angle of the wave or called as Direction Of Arrival (DOA) of Planewave. The method commonly to overcome the problem to utilize the sensor array by the data processing technique such as a beamforming technique. In this research was done by DOA estimation that used technique Fast Fourier Trasnfrom (FFT) beamformer with sensor configuration by Uniform Linear Array (ULA). The analysis has been to determine the distance of the array microphone that has DOA estimation with high accuration to the real source posisition. Based on the variation of distance of array microphone tested, shown the 6 cm is the bes distance which has the most dominant DOA estimation results with high accuracyKeywords : DOA , FFT Beamforming , Array sensor , ULA

Abstract

This paper describes how to record a moving object and save as new video files (* .avi), then filtering the moving objects (Vehicles) by using a Gaussian Mixture Model (GMM) with 2 types of distribution, i.e. Bacground and Foreground distribution. The shape of the foreground distribution is filtered by morphological operations and segmented by using Bit Large Object (BLOB) Segmentation to get the vehicle dimensions. Feature extraction results of these vehicles, will be used as data cluster for vehicles classification by using Fuzzy Cluster Means (FCM). Resulting experiments show good results with 91.3% of accuracy rate.Index Terms—GMM, BLOB, FCM, Classification.

Abstract

Prediksi penjualan adalah salah satu cara untuk meningkatkan laba perusahaan, peramalan diperlukan untuk menyetarakan antara perbedaan waktu yang sekarang dan yang akan datang terhadap kebutuhan, Jaringan Syaraf Tiruan (JST) dapat mengaplikasikan dengan baik metode peramalan.Pendekatan peramalan kuantitatif dengan metode times series akan menentukan nilai data masukan dari sekumpulan data serial atau berkala dari transaksi pada suatu jangka waktu tertentu. Data dibagi menjadi data pelatihan, pengujian dan validasi. Proses peramalan menggunakan metode certainty factor (CFf) sebagai nilai pembanding pada bobot koreksi yang telah di latih dalam jaringan backpropagation untuk prediksi yang optimal. Simulasi program peramalan penjualan mobil honda tahun 2015 dengan variabel input data penjualan daerah 30,000 unit, penjualalan dealer 25.000, penjualan tunai 25.000, CF = 0.5 dan kredit 19.000 menghasilkan ramalan penjualan sebanyak 29579 unit dengan target error 4,205 %.Kata Kunci—Peramalan, Time series, Certainty Factor, JST, Backpropagation.
