Some techniques frequently applied for tomography covers backprojection, Algebraic Reconstruction Technique (ART), and backpropagation. In this paper, frequency selection and image reconstruction techniques for tomography are investigated using parallel-beam projection at microwave frequency. The use of some microwave frequencies of 1.5GHz, 3GHz, and 4.5GHz is intended to determine the characteristics and effect of selected frequency in producing the reconstructed image. A perforated wood is used as a target which is represented by a wood of tree trunk for object measurement. Here, the filtered backprojection and backpropagation techniques are implemented for reconstructing the image of measured object. From the result, it shows that the reconstructed image using backpropagation technique at the frequency of 3GHz has better image quality compared to the ones using filtered backprojection technique.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134634754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of its partner to do the task is Aspemako. Aspemako is an association of business of processed food. In this paper we take a case in Gunung Kidul District. Currently in marketing part, the Aspemako puts its products in a tent in front of the Department, so the market is very small and the business becomes sluggish. In that way Aspemako needs a new means to expand the market to increase their business. The development of the e-marketplace follows water fall process model, like analysis, design, implementation and testing. From the testing it is sure that the e-marketplace is running well and it is a decent tool for Aspemako to increase the market of processed food.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132862922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The economic value of the frequency depends on several parameters, such as the bandwidth of the occupied frequency band, the location of the frequency spectrum, the service area (the size and population density of the covered area), and the type of service provided. Bandwidth license fees are one of the frequency spectrum fee formulas that also considering the economic value, but this formula does not apply to point-to-point microwave links. Bandwidth license fees are only applied for cellular communication application, so it is necessary to analyze how it applies to point-to-point microwave links to provide a proportional cost for each frequency band considering economic and technical value. The application of bandwidth license fee to point-to-point microwave links was analyzed using an analytical model approach from the ITU-R Report SM.2012-4 on all registered point-to-point microwave links. The results shows that the lowest frequency (4400- 5000 MHz) have the highest spectrum fees, with correlation coefficient of average apparatus fee against population density is 0.35 and correlation coefficient of average bandwidth license fee population density is 0.55.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130907441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The form of the characters and the art of making it become a legacy that deserves to be preserved. The difficulty that is often experienced by the community is in terms of remembering the form, pronunciation, and errors in placing Javanese characters pairs and the lack of available references. Coupled with the elimination of curricula regarding regional languages at the SMA / SMK level. This encourages writers to conduct research and build mobile learning applications for Java characters learning. With the aim of producing a Mobile Learning application that can Assist learning and writing Javanese characters to be more interactive so as to motivate the community to learn Javanese characters.The use of the Gesture API technology that functions when the user starts touching the screen and performs the movements that have been determined by the system and understood by the system itself. The steps taken are analyzing the problem regarding the making of this Java characters mobile learning application through observation, interviews and literature studies to be further identified to obtain data from the general public. Then do the system needs analysis, user needs analysis, while the results will be tested using Black Box and Post Study analysis to determine the extent of the usability system to the problems in the communityThe results of the application built in the form of the introduction of Javanese characters with a gesture board, Javanese characters pronunciation in the form of audio visual and Javanese characters quiz writing so that it was more effective and interactive.

The increasing growth of data traffic led to higher demand for broadband communications. This demand problem can be overcome by the use of the 24 GHz band as gigabit wireless networking spectrum. This study aims to see the potential use of the 24 GHz band. Judging from the penetration of internet sevices in various region, the islands with highest population density mostly using mobile broadband. So the solution for spectrum requirements for mobile broadband is to reallocation spectrum with the fast reliable conectivity service. The forecast methodology for 5G spectrum needs adapted from K-ICT for IMT 2020 Korea for two type regions, it consists of three categories areas including dense urban, urban and suburban. Among those region, the region with highest population density has wide spectrum requirement. For mobile broadband services has spectrum requirement over 370MHz and is expected to increase by 10% in 2024.
