Nextcloud and pydio storage are part of an open based cloud computing system. Measuring service quality can be seen from the aspects of throughput, delay, jitter, and packet loss. This research was conducted to compare the upload and download speeds between the nextcloud server and the pydio server. Of the two cloud storage servers, five trial upload and download respectively. Based on the test results showing that the upload and download processes produce final cloud storage data which has the highest average throughput in terms of uploading files of different types and capacities, the next cloud server is 1,934.6 kbps. The cloud storage that has the lowest average packet loss value is balanced, because the two cloud storages get the same packet loss value of 0%. The cloud storage that has the lowest average file upload delay is the nextcloud server at 222,585 ms. The cloud storage that gets the lowest jitter value is the pydio server of 160.56 ms. Meanwhile, for downloading cloud storage files that have the highest average throughput value, nextcloud server is 1,332 kbps. The cloud storage that has the lowest average packet loss value is balanced, because the two cloud storages get the same packet loss value of 0%. The cloud storage that has the lowest average download delay is the nextcloud server at 132,057 ms, while the cloud storage that has the lowest jitter is the nextcloud server at 132,139 ms.</p> Lalu Delsi Samsumar Beni Ari Hidayatulloh Zaenudin Zaenudin Putri Novia Dyah Pitaloca Copyright (c) 2023 2023-07-19 2023-07-19 6 1 1 8 10.56873/jitu.6.1.5015 Analysis on the Impact of Implementing Inter-band Carrier Aggregation (CA) on the 5G-NR Networks <p>Currently, cellular technology is advancing into the 5G era, which can support data speeds up to 10 Gbps on the uplink side and 20 Gbps on the downlink side. This study aims to plan a 5G NR network by implementing the inter-band carrier aggregation (CA) method. CA is one of the techniques used to achieve high data speeds and to combine two or more radio frequency bands. The primary cell uses band n40 at 2300 MHz with a 40 MHz bandwidth, while the secondary cell uses band n78 at 3500 MHz with a 100 MHz bandwidth. The area that we used for this network design is Agung Podomoro Land (APL) Tower Central Park area in West Jakarta. The propagation model used Urban Macro. Testing process is carried out by comparing the results between using CA and not using CA on the SSRSRP, SS-SINR, and data rate parameters. Simulation results show an average increase in each parameter after the inter-band carrier aggregation method is applied. The SS-RSRP parameter increased by 0.05% with a value of -82.02dBm, the SS-SINR parameter increased by 0.77% with a value of 15.71dB, and the data rate parameter significantly increased by 241.33% with a value of 803.66 Mbps. This proves that implementing the carrier aggregation method can improve the quality and capacity of the network, particularly the data rate, by maximizing the use of the bandwidth and resource block produced by the combination of component carriers.</p> Vanessa Agelliza Solichah Larasati Alfin Hikmaturokhman Copyright (c) 2023 2023-07-19 2023-07-19 6 1 9 16 10.56873/jitu.6.1.5106 Parallel Matrix Multiplication Algorithms Acquire Connected Network Motifs <p>The network of interactions between biomolecules is essential to biological processes. Many studies have shown that molecular networks can be analyzed by breaking them down into smaller modules known as network motifs. We hypothesize that identifying the set of possible 5-node motifs and 6-node motifs embedded in a network is a necessary step to elucidate the complex topology of a network. Accomplishing this goal requires determining the complete set of motifs that are composed of five and six connected nodes. &nbsp;</p> <p>We developed a parallel algorithm to reduce time consumption that tackles the exponential problem. It is implemented in matrix multiplication insert in the process of identifying isomorphic patterns and removing the isolated and disconnected patterns. The experiment showed that the parallelization matrix multiplication algorithm is approximately 1.4 times faster than serial programming for identifying 5-node motifs and approximately 1.3 times faster than serial programming for identifying 6-node motifs with all the nodes connected</p> Efendi Zaenudin Ka-Lok Ng Copyright (c) 2023 2023-07-19 2023-07-19 6 1 17 30 10.56873/jitu.6.1.4983 DEVELOPMENT A WEB-BASED STUDENT INTERNSHIP APPLICATION USING LARAVEL FRAMEWORK <p>In this research, the author will discuss the development of a student internship information system implemented using the Laravel framework. The aim is to provide convenience for students in registering/applying for internships, reporting daily activities, submitting final reports, and updating all other internship-related information, as well as facilitating institutions in managing internship data. The method used in this research is the information system development method, which includes literature review, needs analysis, system design, testing, and evaluation. The Laravel framework was chosen because of its good performance, ease of use, and many features that can facilitate the development of information systems. The student internship management information system designed has easy-to-use internship registration and reporting features that can be accessed from anywhere, as well as integrated internship data management features. The results of this research show that the development of a student internship information system using the Laravel framework can provide convenience in registering and reporting internship results for students, as well as help institutions in managing internship data. It is hoped that with the existence of this student internship information system, it can be a solution to simplify and accelerate the internship process and management for students and participating institutions.</p> Muhammad Nugraha Ricak Agus Halimil Fathi Rizki Baginda Copyright (c) 2023 2023-07-19 2023-07-19 6 1 31 38 10.56873/jitu.6.1.5139 Implementation of Collision Avoidance System Algorithm in NPC Game 3D <p>Nowadays, with the rapid development of technology, we are given the convenience of finding entertainment such as games. Now this game can be quickly run on various media, one of them is a smartphone. Most smartphones' operating systems (OS) are Android and IOS. Among the both of OS which is currently popular is Android. This research aims to create an Artificial Intelligent of Non-Player Character (NPC) that can avoid every obstacle using the Collision Avoidance System algorithm. The result of the research is an android game app that applies the Collision Avoidance System that can make AI NPC avoid obstacles. The application of the algorithm to the NPC is made in 3 stages, namely, design by making a flowchart of the algorithm, then writing a program from the Collision Avoidance System, and finally, testing the AI ​​NPC. The test is carried out by comparing the reactions of NPC 1 and NPC 2 in passing through obstacles when on different paths by being carried out jointly between NPC. Based on the tests on AI NPC, NPC managed to avoid obstacles in front of them and the players, and it is almost 93% successful. </p> Gugah Alwan Hamanako Adi Sucipto Copyright (c) 2023 2023-07-19 2023-07-19 6 1 39 44 10.56873/jitu.6.1.4988
