<![CDATA[Seiring dengan pertumbuhan kota yang secara di dunia melebihi 50%, persoalan kota menjadi lebih rumit dan kompleks, salah satunya adalah kemacetan yang dapat disebabkan oleh banjir serta pertumbuhan kendaraan yang melebihi luas jalanan. Hal ini juga terjadi di Kota Makassar sebagai ibu kota provinsi Sulawesi Selatan. Saat ini sering terjadi kemacetan lalu lintas di beberapa ruas jalan di Kota Makassar, terutama pada saat peak hours. Data terakhir Juni 2017 menunjukkan jumlah kendaraan di kota Makassar adalah sebanyak 1.425.635 dimana terjadi kenaikan lebih dari 100% dibandingkan tahun 2007. Pada penelitian ini akan dirancang sebuah aplikasi real time route selection dengan memanfaatkan Wireless Sensor Network sebagai penyedia data traffic condition pada ruas jalan. Algoritma pencarian rute terpendek yang digunakan adalah algoritma Dijkstra serta algoritma Floyd-Warshall yang dikombinasikan dengan fungsi skalar Chebycheff. Hasil penelitian menunjukkan bahwa rute yang dihasilkan oleh kedua algoritma sama tetapi algoritma Dijkstra memiliki waktu pemrosesan lebih cepat dengan rerata 7,45 ms. Kelemahan fungsi skalar Chebycheff adalah proses update jarak antar node yang dinamis bergantung pada perubahan kondisi lalu lintas. Hal ini dapat diatasi dengan menggunakan penggunaan metode inferensi lain untuk kriteria kondisi lalu lintas, seperti fuzzy logic maupun metode Multi Criteria Decision Making.]]>

<![CDATA[With city conditions that often have congestion, a driver need to find a route of the many possible routes that may occur from origin to destination by considering several factors. The weaknesses of the ant algorithm is the dependency of required parameter values and must be set manually. This paper will make improvements to the fuzzy ant colony system (FACS) with minimize parameter dependency by using fuzzy logic to determine the probability of the next node visited by ants. There are four criteria or input variables for fuzzy inference system, that is “Pheromone Intensity”, “Distance”, “Vehicle Intensity”, and “Average Speed”. The routes generated by improved FACS (I-FACS) are more varied than the FACS algorithm. The best condition obtained by I-FACS was at point O/D= 112/34 where at 05:00, I-FACS was able to obtain the route with the best length compared to ACS and FACS. The result of the comparison of the route distance obtained shows that I-FACS is able to produce a better route by 4.16% than FACS by looking at the average distance difference on ACS. This method is expected to be a reference for the development of smart transportation in support of smart mobility, which is one of the components in the smart city concept.]]>

<![CDATA[Along with the development of information technology, is now widely available for image processing applications are easy to use. It has an impact on the process of manipulation and modification of the image to be more easily so it is quite difficult to determine the authenticity of an image. Image evaluation methods have been developed automatically. The weaknesses are irrelevant parts of the image will be processed so as not efficient in terms of processing time. User Role (semi-automatic) for assessing the relevance of an image section can be helpful in the evaluation method. Similarity-based approach, one of them using the Euclidean distance, either automatic or semi-automatic allows forensic computer analysis process becomes faster. Preparation of the ranking of the data that has similarities allows users to investigate the authenticity of the picture. In this paper tried to assess the implementation of semi-automatic evaluation of similarity based on a forensic image. In the method of analysis, there are two stages, namely the conduct of the evaluation results ranking image block that requires verification of the user so that the second stage is only relevant image blocks are analyzed automatically. The results showed that the use of semi-automatic evaluation methods based on computer forensic similarity not only be done on the data string but also the image data.]]>

<![CDATA[The information has become one of the most important parts for an institution today, including Universitas Atma Jaya Makassar. One of the information is academic, so it needs fast processing to get that information. The problems that arise are difference of language between the user who need information and database language which storage data of academic. So we need an interpreter to bridge the difference of language. In this research, the writer uses Natural Language Processing as the solution from that problem and use Parser Noise-Disposal. The application is designed by PHP as programming language and MySQL as database.]]>

<![CDATA[Image completion, inpainting or hole-filling, is the process to fill or replace an area of image with another image so the replacement can not be detected. The replacement area is the area from the image that is similar than image that has the removing area. The feature of color image that can be used is statistic feature, such as mean, median, and standard deviation. Template matching is used to find the area from the similar image. Then, image blending, like Poisson Blending, is used to equalize gradient of the area from the similar image. The image dataset is obtained from LabelMe and the resolution of images is 256x256. The number of training image is 10 images and 3 images as testing images or query images. The accuracy to produce the scene completion is 66.67%.]]>

<![CDATA[With the issuance of PP No. 19 In 2005, Internal Quality Assurance System (SPMI) has become an necessity for an higher education institution that aims to achieve continuous improvement. Most colleges including Universitas Atma Jaya Makassar has implemented a model of management and control system for academic process by relying on the outcome of process, not the concurrent of the process itself. In order to achieve continuous improvement, the quality assurance system needs a control system that not only rely on the outcome but more important is the implementation the process itself. This research aims to develop a prototype model of management and control system of academic process that focuses on the monitoring and evaluating function of the academic process, especially the academic process which runs at the University of Atma Jaya Makassar. This research uses UML methodology based on object-oriented approach to take advantage on computer networks as the supporting technology. The prototype model of the resulting system will help facilitate the implementation and quality assurance of academic process through increased control and evaluation function in a structured academic process and in real time.]]>

<![CDATA[Learning management system, as part of higher education governance, is the process of organizing, planning and supervising the implementation of curriculum in order to achieve the learning objective (LO). PP No. 19 in 2005 and No. 32 in 2013 set the standard for higher education governance quality assurance systems where Internal Quality Assurance System is requiredfor higher education institutions that aim to achieve continuous improvement. The main problem in implementing internal quality assurance is that to achieve continual improvement we need an effective supervision that not only can provide data on the results of implementation but more importantly is the data to the process itself. Generally universities has implemented a system of governance and supervision that rely on the outcome of the process but not how the process done. Meanwhile, in order to achieve continuous improvement required a monitoring and evaluation system that does not rely solely on the output but also data from process. This research aims to develop a system of governance with data and information services to the passage of the academic process, especially at the University of Atma Jaya Makassar. This study uses an object oriented approach with UML design method by utilizing the computer network architecture for wireless and mobile technology as key technology. This research produced a system with the ability to monitor the passage of the lecturing process in realtime in order to improve monitoring, evaluation and quality processes in a structured lectures and concurrent transparent, accountable and responsive.]]>
