<![CDATA[Consumer behavior can be detected by conducting surveys, but this method lacks the depth of analysis to measure consumer behavior. By utilizing technological and scientific advances through the study of neuroscience, especially in neuromarketing, it is hoped to improve the ability to analyze consumer behavior. Neuromarketing has been widely used to measure consumer behavior through several stimuli, including logo colors. Neuromarketing to the human brain's response is done using electroencephalography (EEG) signal analysis. Data collection was carried out on six students aged 19-24 years. Subjects were given a stimulus of five original logo colors and five logo colors recolored with the number of questions in three sessions. Pre-processing uses a butterwort horde four bandpass filter with a theta-band frequency band in the frequency range of 4-8 Hz. Data on color changes using questionnaires and EEG signal data is processed on spatial and spectral domains to view active areas of short-term memory. The result obtained is the effect of the change in logo color on consumer memory and the active location of short-term memory on the logo's color. Using spatial selection, the number of channels was reduced from 16 to 4 channels or by 75%. The selected channels are in the memory and visual areas.]]>

<![CDATA[As time passes by, the increasing demands from 4G technology services to 5G technology are getting bigger. In line with the development of 5G, there are several open sources such as Free5gc, Open5gs which already provide core 5G network services so that they can help create and simulate private 5G networks. By using free5gc open source, it still needs more attention from the security side, especially from common attacks such as DDoS. Then the attack scenario is carried out from the inner network side, namely from the UE with the TCP SYN Flood and Ping of Death attack methods. The results of the attack contained comparisons for CPU and memory usage parameters. Then the TCP SYN Flood attack had an impact on the core network function components, namely Access and Mobility Management (AMF), which in 5G services experienced errors or crashes after receiving large packets. Thus, users cannot use the service because if an error occurs in the core network function (AMF), then the connection to gNB and the UE will also be lost]]>

<![CDATA[Vehicle tracking using the positioning system that is used today is the single point positioning method implementation, but the accuracy of the method is still inadequate for further features to be applied. Therefore, an accuracy improvement is needed. By applying the Real Time Kinematic (RTK) method which has an centimeter level of accuracy, the IndiCar webapp made by PT. Telkom Indonesia offers further features in driving, such as sudden vehicle movements detection, to accidents indications. Accuracy comparisons can also be made to define how significant the difference in accuracy of the two methods. The tests show quite significant results. At single point positioning, the largest deviation is at 20 m and the smallest at 1.0960 m, while in the RTK method, the largest deviation is at a value of 80 cm while the smallest at 0.92 cm. The standard deviation value is then used in the calculation of accuracy. With CEP calculations, the single point positioning method produces accuracy at 5.4659 m, while the RTK method provides a more precise level of accuracy, with a value of 18.22 cm. These results show that the RTK method can be an alternative, to improve accuracy in the use of positioning systems.]]>

<![CDATA[Tuberculosis (TB) is an infectious disease that can be detected using a sputum sample. TB cases in Indonesia have spread throughout the region; the highest cases are in West Java. This problem makes the government do some handling and prevention of TB disease. The Bandung City Health Office (DKKB) conducted a cross-test to diagnose TB using a sputum sample. So in this study, a TB bacteria detection system, namely Mycobacterium Tuberculosis (MTB), will be made in sputum samples and their number to diagnose TB. Detection and calculation of the number of MTB are done by processing the image on the sputum sample using the watershed contour detection method. In this study, sputum sample data were obtained from DKKB. The acquisition of microscopic images at each point of the field of view is carried out using an SLR camera connected directly to the microscope to replace the function of the ocular lens. In this study, the microscopic sputum sample images were classified into positive and negative using the watershed and colorspace methods and were tested on a total of 90 microscopic images. From the system testing results, the system accuracy level is 100%, and the system precision is 100% for the detection of TB diagnosis. The system processing time averaged 5.811 seconds for 90 images used.]]>

<![CDATA[NDNS is DNS embedded in Named Data Network (NDN) architecture as a distributed database system to support NDN caching and know the content's location. In this research, the simulation performed using two topologies, Abilene and PAN-Europe with changes to their prefixes. This simulation conducted to see performance of NDNS with minimal ability to cache on NDN router or Caching Resolver. From simulation results, the variation of prefix at Second Level Domain and Top Level Domain there is no difference in average delay in both topologies, namely 1% increase in average delay as the variation of prefix increases. There is a decrease in the Cache Hit Ratio by 0.16% (Abilene) and 0.18% (PAN-Europe) because the probability of getting cached data decreases as the prefix varies. In the change in interest frequency, there is an increase of 0.4% in average delay and the Cache Hit Ratio decreases by 0.08% in both topologies as the frequency of interest per second increases. NDNS with cache in Router and Caching Resolver get 43% lower average delay (Abilene) and 44% (PAN-Europe) than NDN with cache in Router and 57% lower (Abilene) and 60% (PAN-Europe) than NDNS with cache in Caching Resolver only.]]>

<![CDATA[Educational games are very suitable for learning for children because the gameplay is not so heavy and is based on the same conditions as everyday life, which certainly does not contain bad elements that are inappropriate for children. The output of educational games that will be used for learning must really be considered because the age of kindergarten children is the age at which children's character and manners are formed. In this research, the writer will develop a game with a labyrinth concept which carries the theme "Caring for the Environment". The author adds the Non-Player Character (NPC) feature in the game which requires behavior design using the Finite State Machine algorithm with three working principles State, Event (happening), Action. The result of this research is that all the features in the developed game design have been implemented and function properly, especially the finite state machine method which is applied to NPC behavior. The Maze Game Educational Game that was developed succeeded in attracting the interest of the children who played it and the "Care for the Environment" content in this game was easy for children to understand.]]>
