Abstract

Coronavirus (COVID-19) is a rapidly emerging and spreading infectious disease. To minimize the impact caused by the virus, it is necessary to have a vaccine. However, the existence of vaccinations for the Indonesian people has caused controversy so that it invites many people to give an opinion assessment, therefore people choose social media as a place to channel their opinions. In this study, a comparison was made with an observational infoveillance study by collecting data using a Python programming script (Python Software Foundation) to display posts related to the COVID-19 vaccine on Twitter as well as quantitative and qualitative analysis to identify trends and characterize the main themes discussed by twitter users on Twitter. Indonesia. Our research collects data through social media Twitter in the period August 2020 - March 2021. In this study we combine Retrospective Observation and Sentiment Analysis, with the aim of producing periodic timeline evaluations within a predetermined time frame. In this study author found that there was an interaction increase in positive posts due to officially reported developments, on the other hand we were quite difficult to understand the factors behind the emergence of negative posts but we made a conclusion based on the results of sentiment analysis that most of the negative posts were caused by lack of information and understanding of vaccines and vaccines. the COVID-19 outbreak itself.

Abstract

The development of technology today has become the most important thing in society. This causes the wider information that can be accessed by the public in Indonesia, especially on vaccination activities in the Banyumas area, the people of Banyumas can access the website to carry out vaccination activities. Processes that use technology anywhere and anytime. This study analyzes the quality of the website vaberaya.banyumaskab.go.id using the Delone and McLean Success Model with reference to 6 variables including information quality, system quality, service quality, user satisfaction, usage, and net benefits. This sampling uses questionnaire data with 100 users as respondents who have used the vaberaya.banyumaskab.go.id website. The method in data processing uses a structural equation model or Structure Equation Modeling (SEM), with the help of SmartPLS.

Abstract

Cibangkong Village is one of the villages in Pekuncen District, Banyumas Regency. The number of recipients of PKH cards (Program Keluarga Harapan) is 253 families, data on KPM (Beneficiary Families) prospective recipients of BPNT (Non-Cash Food Assistance) are 278 families, and data for recipients of BLT (Direct Cash Assistance) village funds are 217 people (source Cibangkong Village in 2021). With so many recipients of this assistance, village officials encountered several obstacles, one of which was that the recipients were not eligible to receive assistance. This needs to be handled, one of which is by creating a Decision Support System that can assist village officials in overcoming these problems. Decision Support System (DSS) is a system that can assist a person in making accurate and targeted decisions. This study aims to produce a Decision Support System for receiving social assistance from the Family Hope Program (PKH) in Cibangkong village. This research uses the Multi Attribute Utility Theory (MAUT) method. The result of this research is that the making of a decision support system for receiving social assistance for the Family Hope Program (PHK) in Cibangkong village can be used as a tool by the Cibangkong village apparatus to consider the feasibility of prospective recipients of PKH social assistance. The criteria used in the Decision Support System for receiving social assistance from the Family Hope Program (PHK) in Cibangkong village are 12, namely income, savings, consuming meat, milk and chicken, ability to pay for treatment, education of the head of the family, building area, type of floor, house walls , latrines/WC, lighting sources, drinking water sources, and cooking fuel.

Abstract

For understanding the learning effect, the gaze tracking is a more objective method to collect the data on eye movement and used to analyze the learning behaviors. In order to provide an analysis tool to apply in diverse environments, an adaptive gaze tracking system is proposed in this paper. This system can offer helpful suggestions for educators when improving the instruction. Additionally, the experimental results show that the estimation of gaze points was successful even when the distance and head rotation alter.

Abstract

Purpose: The study aims to assess the effect of knowledge management on strategic management in the General Administration of Education in Jeddah, Saudi Arabia. Design/methodology/approach: The research employed a quantitative method and descriptive analysis was conducted using SPSS21 and AMOS 23. The design, which has six independent variables and a single dependent variable. The study uses the questionnaire tool, a questionnaire was developed by the researcher, and distributed to a sample of 316 employees of the General Administration of Education in Jeddah in Saudi Arabia. and the questionnaire is two-part. The first is for primary verses such as age, experience, degree of employment, scientific qualification, and average income, and the second part is to address the knowledge management dimensions (knowledge distribution, knowledge acquisition, knowledge diagnosis, knowledge storage, knowledge generation, knowledge application) and its relationship to strategic management practices, the testing measurement validity and reliability could be occurred by EFA then analyzed the data by using multi regression .The study is based on the descriptive analytical approach to suit its purposes, free from reviewing and reviewing the theoretical literature on knowledge management and strategic management practices, in addition to reviewing previous relevant studies. Findings: knowledge management processes impact on Strategic Management Practices when testing the relationship between knowledge management processes and strategic management practices by structural equation modeling SEM, but the knowledge acquisition has no significant effect on strategic management practices.Research limitations/implications: The research was applied to the General Administration of Education in Jeddah, in Saudi Arabia, and the research was limited to the city of Jeddah only, and these tools can also be applied to other government institutions, especially in departments that work in providing services to the public. It is believed that knowledge management will have a role Effective if it is applied in service institutions that seek to apply strategic management to meet the increasing needs of the public.Originality/value: The paper is of theoretical and practical importance, as the theoretical importance is the literary addition to which research contributes to the theoretical enrichment of scientific literature on knowledge management and strategic management practices, The paper also has its applied importance as it deals with the effect of knowledge management on implementing strategic management practices. This will be applied in Jeddah, Saudi Arabia, which contributes to developing strategic performance based on knowledge management.

Abstract

In this paper, we propose a high capacity data hiding method applying in binary images. Since a binary image has only two colors, black or white, it is hard to hide data imperceptible. The capacities and imperception are always in a trade-off problem. Before embedding we shuffle the secret data by a pseudo-random number generator to keep more secure. We divide the host image into several non-overlapping (2n+1) by (2n+1) sub-blocks in an M by N host image as many as possible, where n can equal 1, 2, 3 , …, or min(M,N). Then we partition each sub-block into four overlapping (n+1) by (n+1) sub-blocks. We skip the all blacks or all whites in each (2n+1) by (2n+1) sub-blocks. We consider all four (n+1) by (n+1) sub-blocks to check the XOR between the non overlapping parts and center pixel of the (2n+1) by (2n+1) sub-block, it embed n 2 bits in each (n+1) by (n+1) sub-block, totally are 4*n 2 . The entire host image can be embedded 4×n 2×M/(2n+1)×N/(2n+1) bits. The extraction way is simply to test the XOR between center pixel with their non-overlapping part of each sub-block. All embedding bits are collected and shuffled back to the original order. The adaptive means the partitioning sub-block may affect the capacities and imperception that we want to select. The experimental results show that the method provides the large embedding capacity and keeps imperceptible and reveal the host image lossless.
