Abstract

In this research, cryptography of SALSA20 stream cipher technique combined with BPCS steganography technique was used to enhance the security layer in mobile communication. SALSA20 technique has been proven as one of the best stream cipher algorithm candidate according to eSTREAM portfolio report in 2012. The combination of SALSA cryptography and BPCS steganography technique can provide more security layer of digital image data as the research objective. The results from this research showed that combination of SALSA20 and BPCS technique need average time of 19.400s for the encryption and 21.900s for decryption process. The average memory (RAM) usage of these two technique is about 23.354 MB/s for the encryption process and 36.057 MB/s for the decryption. The analysis of component MSE and PSNR show a good result with value of 16.21259 dB for the MSE component and +44.08686 dB for the PSNR, with color contrast intensity distribution of the output image nearly identical to the original cover image.Keywords—BPCS, Cryptography, SALSA20, Steganography.

Abstract

Maximum Power Point Tracking is a method to track power point of an energy source in order to generate maximum power. One of the MPPT method for photovoltaic system is fractional open voltage MPPT. In this paper the fractional open voltage MPPT is modified by using artificial neural network trained using genetic algorithm. Artificial neural networks are successfully trained by using genetic algorithm. The best mean squared error (MSE) value obtained is 0.000453. The network tested using test data, yielding average error = 0.00949509 and MSE = 0.00012814. The neural network-based MPPT can improve the fractional open voltage MPPT by 4.79%.Index Terms---Genetic Algorithm, MPPT, Neural Network, Photovoltaic

Abstract

This research focused on modification ACO algorithm. The purpose of this research was to obtain better performance by modifying the algorithm of Ant Colony Optimization (ACO), particularly in terms of computational speed while maintaining the quality of the solution. Modifications made in this research is the calculation of the probability of the next city to be visit, the ant trail intensity calculations, and modification number of ants to follow the size of the problem. From the results of this research it can be concluded that by modifying the probability of the next city to be visit and the intensity of the ant trail can maintain the quality of the resulting solution with a percentage of 99.8% while the number of ants that used 35% of the size of the problem. In terms of memory usage, modification ACO algorithm is more efficient than the original ACO algorithm with an average of 7%. In addition, the time required to generate the shortest path on average three times faster than the original ACO.Keywords – ACO, ACO Modified, Shortest Path

Abstract

Teknologi diciptakan untuk membantu pekerjaan manusia agar mudah, cepat, tepat, akurat dan efisien. Penerapan teknologi dimanfaatkan dalam semua bidang, salah satu wujud penerapan sistem teknologi dalam bidang pendidikan yaitu sebagai alat bantu penghafal warna bagi balita. Alat ini merupakan alat peraga edukatif berupa alat pengenal warna yang diharapkan dapat membantu balita dalam mengenali berbagai macam warna sehingga anak-anak dapat bermain sekaligus juga dapat mengenal serta menghafal warna yang terdapat disekelilingnya. Alat ini dirancang menggunakan sensor warna yang didesain untuk mengenali warna objek. Sensor warna merubah besaran fisik (warna) menjadi sebuah sinyal kotak yang mempunyai frekuensi yang berbeda-beda untuk setiap pembacaan warna. Mikrokontroler yang digunakan sebagai pengendali sistem adalah ATmega16, ISD25120 (Information Storage Device 25120) digunakan sebagai penyimpan database suara, LM386 sebagai penguat sinyal audio dan speaker 8 ohm. Perangkat lunak dirancang untuk mengolah data masukan berupa frekuensi sensor warna, mencari frekuensi yang sesuai dengan database memori dan mengeluarkan warna yang sesuai melalui suara. Pengujian dilakukan dengan menggunakan warna yang berbeda-beda. Hasil pengujian menunjukkan bahwa alat dapat mendeteksi warna benda yang ingin dikenali warnanya serta mengeluarkan dalam bentuk suara sesuai dengan warna benda tersebut.Kata Kunci— warna , sensor warna, ISD25120, suara

Abstract

The best solution of the problem of electrical energy crisis in Indonesia, with the utilization of renewable energy sources that are environmentally friendly, economical, sustainable, and technically easily to implemented. The model system proposed in this paper is the Photovoltaic Distributed Generation (PVDG). This paper discuss modeling PVDG by searching injection placement and size us Genetic Algorithm. Optimization is done with the concept of the four scenarios increase the value of the injection. The scenario used was an increase in injection rate + 10%, + 20% + 30% and + 40% from the initial source of generation. The obtained results show the system ideal conditions is contained in the scenario-4. The results found that 8 locations with a variety of sizing power. PVDG scenario-4 modeling results show the ability of the system to minimize power loss from 13,15% to 1,30% and the highest voltage drop -25% to -8,5% of nominal voltage.Index Terms—Photovoltaic, Distributed Generations, PVDG, Genetic Algorithm.

Abstract

Dissolved gas analysis of transformer oil is one of the most effective ways to determine the transformer condition. Currently, there are many interpretation techniques that have been used in data processing of dissolved gas analysis results. However, all of the techniques used are rely based on the experience of experts who have conducted research by using the results of dissolved gas analysis. The combination of expert system and fuzzy to diagnose the dissolved gas analysis data to identify the condition of the transformer is discussed in this paper. The data used for this research is collected from several different transformers and then interpreted by using a standard methods and fuzzy expert systems, and the results are compared. From several experiments show that fuzzy expert system is more effective to identify a transformer failure.Keyword---DGA, Dissolved Gas Analysis, Fuzzy Expert System, TDCG.

Abstract

This paper discusses the evaluation of the electrical system at the Polytechnic of Ambon. Problems arise when this is a very poor network conditions that supply to each building. In some buildings often have on limiting current trip. This occurs because the addition of the load from time to time but was not followed by changes in installations that meet the standards. Evaluation is done with the help softwaare Docwin and Matlab. These include standardization of electrical networks, voltage profile, the data load and network installation. Evaluation results show that the current network conditions is not feasible and over load. Improvements to the current network is also proposed in this paper, because the proposal to be considered in the planning of the electrical network repair Polytechnic Campus Ambon in the future.Index Terms — Evaluation, planning, electric network System, Polytecnic of Ambon, DocWin and Matlap.

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
