Abstract

Customer knowledge is a valuable asset, and gathering, managing, and sharing customer knowledge can be a useful competitive activity for organizations. Successful knowledge partnerships with essential and valuable customers can strengthen business performance and create an absolute competitive advantage that is difficult for competitors to emulate. In consumer knowledge management, companies often experience significant obstacles or constraints so that sometimes many companies prevent them from managing consumer knowledge. The company or organization depends on consumers who do not need to understand the industrial field of the company or organization. This paper discusses the comparison of the application of customer knowledge management in various industries. Research findings that all organizations must apply the three essential components of customer-related knowledge within the underlying conceptual framework. Three basic components of customer-related knowledge within a basic conceptual framework: knowledge for customers, knowledge of customers, and customer knowledge, cannot be eliminated. This proves the compatibility with previous studies. In fact, to succeed, they must be applied so that it is of value to the company. Implementation of the framework can present a great opportunity for the organization or company to make new products so that this will improve the performance of the company or organization and maintain the continuity of the company or organization.

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

Embarrassment has been an important research issue in the domain of management. Previous studies indicated when embarrassment occurred between sales and customers, it could reduce the customers' intention to visit the store again. Virtual communities are also places for interaction between members; therefore, embarrassment could occurred as well. Goffman’s dramaturgic theory can be perfectly applied to the settings of virtual communities. They both address the interaction facet between people. Dramaturgic theory can also elaborate the occurrence of embarrassment. Thus, this study aims to resolve the possible reasons inducing embarrassment by dramaturgic perspective, and investigate the influence and moderators of embarrassment on members' continual usage and knowledge sharing intention towards virtual communities. In addition, two sets of interference variables were derived based on virtual community characteristics, and their influence on the above-mentioned correlations was analyzed. The research results can be a good reference for virtual community operators and managers to help them understand those causes of embarrassment that have a negative impact on those community members’ intentions, and to reflect on how they can reduce those causal factors by tweaking the design of community platforms.

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

This study focuses on the use of an important IT innovation--software-as-a-service (SaaS), and draw on sensemaking and the dedication-constraint framework to explain the formation of SaaS commitment. Building on and extending prior studies, we posit that managers’ perceived relational value from SaaS consumption transforms their initial sensemaking of SaaS features into commitment. SaaS features are characterized as strength frames and weakness frames. Perceived relational values are conceptualized as process flexibility, task-knowledge coordination, process specificity, and trust. The proposed model and hypotheses are largely supported by the empirical data from 169 SaaS client firms. We discuss theoretical and practical implications.
