With the discovery of paperless expensive means of internet access, network communication via social media is on the rise, which often comprises threats and distortions. Un authenticates identification may sometimes lead to ambiguities in end-user identification and misunderstandings. Therefore, proper identification of a person is a must in network communication. Image private watermarking[7][9][19] is one solution when the owner of the digital images are identified properly by embedding additional information such as a private watermark in the digital images like fingerprint and retina imperceptibly concealed inside another image. On the other hand, communication also leads to a serious surge in decompress technique on the images. This work introduces three techniques: digital watermarking, steganography, ICA[4][5][6][20][22]. Using a private watermark using the visible [9][7] and non-blind[9][19][7] technique on the photo image. Then two original fingerprints and retina images to achieve stego analysis technique to convert as a stego image. Then the stego image concealed by a watermarked photo image. Then mixing the two techniques to achieve the ICA[20][22][4][5][6] (Independent Component Analysis) for protecting data transmission. To providing compression using the IDCT (Inverse Discrete Cosine Transform) technique with the key using AES[10][9][19] (Advanced Encryption Standard) 64-bit algorithm. Implementation and to determine the utilize the JAVA platform.

Corona virus or covid 19 is a dangerous virus that attacks the human respiratory system. Corona virus able to change the order of almost all of life’s joints in the world of education. In order to break the chain of the covid 19, goverments introduce a pattern of long range learning by means online learning. Application of this learning model certainly brings its own impact to students. The puspose of this study is to know the impact students are experiencing class 5 country primary school Pandawei during the online learning system. The method used was qualitative research methods with data collection techniques thrugh interviews and observations. The analysis technique used is qualitative descriptive. The main find of this research is increased students study habits using this online learning methods because the students are becoming accustomed  with technology so they’re easier discovering additional information about the lesson materials received search school.

The purpose of this study is to analyze the influence of motivational leadership and job satisfaction on the performance of South Kalimantan Police Biddokes personnel. The benefits obtained from this study are providing input or additional information that is meaningful to organizations, companies and further research on leadership, motivation, and job satisfaction with employee performance as a reference for further research.This research variable consists of indentpent variables and dependent variables. The independent variable consists of leadership, motivation and job satisfaction. Whereas the dependent variable consists of employee performance. The analysis technique used is multiple regression (multiple regression) with the help of SPSS 20.0 software.The results of the Leadership, Work Motivation, and Job Satisfaction research of the South Kalimantan Police of Biddokkes went well. Leadership, work motivation, and job satisfaction have a partial effect on the performance of the South Kalimantan Regional Police Biddokkes. Leadership, work motivation, and job satisfaction simultaneously influence the performance of the South Kalimantan Police Biddokkes. Leadership has a dominant effect on the performance of the South Kalimantan Regional Police Biddokkes compared to work motivation and job satisfaction.

As part of the overarching research goal to assess current and potential maritime information sources for use in maritime defence and security in the Canadian north, we examine whether wide-area surveillance data, as represented by Space-based Automatic Identification System (S-AIS) data, offers sufficient information for surveillance requirements in the Canadian north. If S-AIS data are not sufficient, we address how the additional information provided by Long-Range Identification and Tracking (LRIT) can be used to meet the surveillance requirements. A Systems Tool Kit (STK) simulation scenario is constructed that includes five exactEarth satellites collecting AIS data. Simulated AIS transmitters are positioned at 20 northern Canada ground locations. The results indicate that for each location, two thirds of the eight-day simulation is spent without a satellite within range, when using the five satellites. As the number of satellites decreases, intervals in the range of 80 to 105 minutes, during which there are no AIS messages received, increase in frequency. If the end-user requires vessel location information more often than S-AIS consistently provides, augmenting the S-AIS information with LRIT polling should achieve the desired vessel traffic awareness.

In this Game , we implement a character designer at the enemy by applying the algorithm A * pathfinding Algorithm. Furthermore, A * is as the algorithm for searching solutions with the use of additional information (heuristics) in which it is an optimal solution. The purpose of developing this Adventure Game  is A * Algorithm implementation for Pathfinding using Unity 3D. Pathfinding is the fastest path of searching process from point of origin to point of destination by avoiding the various barriers along the path traveled without crashing the existing barrier along the way. Its design and development applies Unity 3D. The test result of algorithm in the Game  shows that the total of passed node result is 50 nodes. It is similar with the previous manual count result. Furthermore, the Game  route shows that its passed path is similar with manual count.

Integrated access and bachhaul (IAB), introduced in 3GPP Release 16, is expected to be one of the main enablers for dense deployments in mmWave spectrum. The IAB architecture brings in topology changes, which impact network-related aspects, such as ensuring robust routing of traffic and load-balancing. While an IAB network should be transparent to the UE, its topology design may affect the end-user performance. Of particular importance in these first releases, hence, is to determine and evaluate optimal IAB topologies. This paper addresses optimal organisation of IAB nodes by considering a number of inter-connected aspects, including maximum number of hops, path-length, load balancing between the IAB-donors and traffic demand in the access network. In that, we focus on one of the parameters most sensitive to the architectural changes in the network - delay. Our analysis relies on the connectivity graph obtained by considering some practical aspects of sectorised beamforming using real mmWave antenna patterns.

The purpose of this study was to obtain empirical evidence of the influence of organizational culture, work environment and compensation on employee performance at the Srinadi Klungkung Market Cooperative. This research was conducted at the Srinadi Klungkung Market Cooperative. The number of samples taken as many as 50 employees accounting and finance section, with non probability sampling method with purposive sampling technique. Data collection is done through a questionnaire. The analysis technique used is multiple linear regression. Based on the results of the analysis it was found that organizational culture, work environment and compensation had a positive effect on employee performance. This shows that with a good organizational culture and environment, and giving compensation to employees, employee performance will increase. The results of this study can provide additional information in empirical studies regarding the influence of organizational culture, work environment and compensation on employee performance. Keywords: Organizational Culture; Work Environment; Compensation; Employee Performance.
