Abstract

Bertambahnya pertumbuhan industri, penggunaan alat elektronik untuk kebutuhan kantor dan rumah tangga menjadi kontribusi peningkatan konsumsi energi pada setiap tahunnya sehingga berpotensi menimbulkan pemborosan pemakaian energi yang berdampak pada lingkungan dan pemanasan global. Pengendalian konsumsi energi listrik oleh pemerintah dan organisasi peduli ingkungan melalui kampanye kesadaran hemat energi pada masyarakat dinilai belum cukup efektif dan efisien. Penelitian ini membuat purwarupa sistem embedded cerdas yang dapat mengendalikan penggunaan peralatan elektronik menggunakan metode Logika Fuzzy sehingga pengendalian konsumsi energi listrik dapat dilakukan secara otomatis. Sistem ini dirancang dengan menggunakan mikrokontroller Arduino Nano yang diintegrasikan dengan sensor suhu, sensor gerak dan modul Real Time Clock (RTC). Pada tahap pengujian kinerja, sistem ini dihubungkan dengan berbagai peralatan elektronik seperti pendingin ruangan, lampu, dan tempat penghubung arus listrik (stopkontak). Berdasarkan hasil pengujian dapat disimpulkan bahwa penerapan sistem embedded cerdas mampu mengendalikan konsumsi energi dan menghemat energi listrik hingga 28,71%.

Abstract

Multi criteria, which are generally used for decision analysis, have certain characteristics that relate to the purpose of the decision. Multi criteria have complex structures and have different weights depending upon the consideration of assessors and the purpose of the decision also. Expert’s judgment will be used to detect the criteria weights that applied by assessors. The aim of this study is a model to detect the criteria weights and biases on the subcontractor selection and detecting the significant weights, as decisive criteria. A method, which is used to modeling the weights detection, is the Solver Application. Data, totaling 40 sets, has been collected that consist of the assessor’s assessment and the expert’s judgment. The result is a pattern of weights and biases detection. The proposed model have been able to detect of 20 criteria weights and biases, that consist of 4 criteria in  the total weights of 60% (as decisive criteria) and 16 criteria in the total weights of 40%. A model has been built by training process performed by the Solver, which the result for MSE training is 9.73711e-08 and for MSE validation is 0.00900528. Novelty in the study is a model to detect pattern of weights criteria and biases on subcontractor selection by transferring the expert's judgment using Solver Application.

Abstract

Ancient document usually contains multiple noises such as uneven-background, show-through, water-spilling, spots, and blur text. The noise will affect the binarization process. Binarization is an extremely important process in image processing, especially for character recognition. This paper presents an improvement to Nina binarization technique. Improvements were achieved by reducing processing steps and replacing median filtering by Wiener filtering. First, the document background was approximated by using Wiener filter, and then image subtraction was applied. Furthermore, the manuscript contrast was adjusted by mapping intensity of image value using intensity transformation method. Next, the local Otsu thresholding was applied. For removing spotting noise, we applied labeled connected component. The proposed method had been testing on H-DIBCO 2014 and degraded Jawi handwritten ancient documents. It performed better regarding recall and precision values, as compared to Otsu, Niblack, Sauvola, Lu, Su, and Nina, especially in the documents with show-through, water-spilling and combination noises.

Abstract

For a long time, random numbers have been used in many fields of application. Much work has been conducted to generate truly random numbers and is still in progress. A popular method for generating random numbers is a linear-feedback shift register (LFSR). Even though a lot of work has been done using this method to search for truly random numbers, it is an area that continues to attract interest. Therefore, this paper proposes a circuit for generating random numbers. The proposed circuit is designed to produce different sequences of numbers. Two segments of Fibonacci LFSR are used to form a generator that can produce more varied random numbers. The proposed design consists of blocks: segment 1, segment 2, and a clock controller. The system produces random numbers based on an external clock. The clock signal for the first segment is that of the external clock, whereas that for the second segment is modified by the clock controller. The second stage (segment 2) is executed only after every 2n1−1 clock cycles. The proposed design can generate different sequences of random numbers compare to those of the conventional methods. The period of the proposed system is less than that of the original Fibonacci LFSR. However, the period is almost equal to the original one when the system is realized in 32-bit or 64-bit form. Finally, the proposed design is implemented on a field-programmable gate array (FPGA). It occupies more area and runs at a lower frequency compared with the original Fibonacci LFSR. However, the proposed design is more efficient than the segmented leap-ahead method concerning space occupancy.

Abstract

This paper presents Multi-Objective Integer Non-Linear Programming (MOINLP) involving Negative Total Float (NTF) for improving the basic model of Multi-Objective Programming (MOP) in case the optimization of the additional cost for Project Scheduling Compression (PSC). Using the basic MOP to solve the more complex problems is a challenging task. We suspect that Negative Total Float (NTF) having an indication to make the basic MOP to solve the more general case, both simple and complex of PSC. The purpose of this research is identifying the conflicting objectives in PSC problem using NTF and improving MOINLP by involving the NTF parameter to solve the PSC problem. The Solver Application, which is an add-in of MS Excel, is used to perform optimization process to the model developed. The results show that NTF has an important role to identify the conflicting objectives in PSC. We define NTF is an automatic maximum value of the activity duration reduction to achieve due date of PSC. Furthermore, the use of NTF as a constraint in MOINLP can solve the more general case for both simple and complex PSC problem. Base on the condition, we state that the basic MOP is still significant to solve the PSC complex problems using MOINLP as a sophisticated MOP technique.

Abstract

Penelitian ini membahas perbandingan kinerja dua perangkat berbasis Android dan Embedded system dalam melakukan pembacaan tag Near Field Communication.  Android dengan modul NFC NXP PN544 dan Embedded system dengan modul MFRC522. Studi kasus yang dilakukan untuk penelitian ini dengan menerapkannya pada manajemen aset. Penelitian ini bertujuan mengetahui kinerja dari kedua perangkat tersebut terdapat perbedaan signifikan atau tidak. Untuk mengetahui hal tersebut, penelitian ini menggunakan metode statistik uji Mann Whitney yang menghitung variabel waktu dan jarak ketika tag NFC berhasil terdeteksi, membaca, dan menampilkan informasi. Dengan metode uji Mann Whitney tersebut dapat diketahui terdapat perbedaan signifikan dari kedua perangkat tersebut berdasarkan hasil yang didapatkan. Setelah dilakukan pengujian, jarak efektif pada kedua alat didapatkan pada jarak 15 mm, 10 mm, dan 5 mm dengan pengujian pembacaan 15 tag NFC pada setiap jarak. Kemudian hasil tersebut diuji dengan metode Mann Whitney pada jarak 15 mm didapatkan nilai signifikasi sebesar .001, kemudian pada jarak 10 mm didapatkan nilai signifikasi sebesar .000, serta jarak 5 mm didapatkan nilai signifikasi sebesar .000 dan dari ketiga pengujian tersebut membuktikan bahwa kedua perangkat terdapat perbedaan signifikan dalam melakukan pembacaan tag NFC.

Abstract

In recent years, cross spectral matching has been gaining attention in various biometric systems for identification and verification purposes. Cross spectral matching allows images taken under different electromagnetic spectrums to match each other. In cross spectral matching, one of the keys for successful matching is determined by the features used for representing an image. Therefore, the feature extraction step becomes an essential task. Researchers have improved matching accuracy by developing robust features. This paper presents most commonly selected features used in cross spectral matching. This survey covers basic concepts of cross spectral matching, visual and thermal features extraction, and state of the art descriptors. In the end, this paper provides a description of better feature selection methods in cross spectral matching.
