Abstract

The government and stakeholders with smart city concept can take advantage of communication technology, a network that has grown rapidly to date for all the needs of urban challenges. The challenges of government services that must be shortened, cut distances, and information disclosure can begin to be resolved with the concept of a smart city with its various products. The technology acceptance model combined with the cultural moderator has been used by several researchers for acceptance testing, one of which is this paper. Research and survey data collection were processed using Smart PLS 3.2 with Sequential Equation Modeling in Yogyakarta, Indonesia. This is unique to discuss because the p-value of Long Term Orientation (LT) is 0.386 which means that it does not significantly moderate behavior. This is interesting to be presented in publications, because Indonesia is a country with a high Long Term orientation value or a pragmatic society. Pragmatic societies tend to be more flexible in adjusting traditions, with the current context, and easy to adapt. Our supporting findings are that respondents who have tried using JSS are still given the opportunity to use conventional methods in government services.

Abstract

Data warehouses are loaded with data from sources such as operational data bases. Failure of loading process or failure of any of the process such as extraction or transformation is expensive because of the non-availability of data for analysis. With the advent of e-commerce and many real time application analysis of data in real time becomes a norm and hence any misses while the data is being loaded into data warehouse needs to be handled in an efficient and optimized way. The techniques to handle failure of process to populate the data are very much important as the actual loading process. Alternative arrangement needs to be made for in case of failure so that processes of populating the data warehouse are done in time. This paper explores the various ways through which a failed process of populating the data warehouse could be resumed. Various resumption techniques are compared and a novel block based technique is proposed to improve one of the existing resumption techniques.

Abstract

To date many Information Technology Companies in Indonesia implement Scrum Framework which is one of the frameworks that uses Agile principles.  The implementation of the Scrum Framework does not guarantee that these companies will be free from risk, since many risks will also appear during the implementation of the framework itself.  Therefore, risk management strategies are needed to mitigate these risks.  This research is a qualitative research to manage risk due to the implementation of Scrum Framework in software development of IT companies, especially in Indonesia.  Interviews have been conducted to the Scrum stakeholders in three IT Companies to gather some initial data to be analyzed further using Qualitative Content Analysis Method and Risk Breakdown Structure.  Our finding show that there is 17 Risk Registers and their Mitigation Strategies for the implementation of Scrum Framework in Indonesian IT Companies. Furthermore, it can be used as guidelines for decision making about whether to implement this framework in their core businesses.

Abstract

Web applications are needed as a solution to the use of internet technology that can be accessed globally, capable of displaying information that is rich in content, cost effective, easy to use and can also be accessed by anyone, anytime and anywhere. In the second quarter of 2020, Wearesocial released information related to internet users in the world around 4.54 billion with 59% penetration. People become very dependent on the internet and also technology. This condition was also triggered due to the Covid-19 pandemic.One thing that becomes an issue on website application security is internet attacks on website platforms and we never expected the vulnerability. One type of attack or security threat that often arises and often occurs is Cross Site Scripting (XSS). XSS is one of Top 10 Open Web Application Security Projects (OWASP) lists.There are several alternatives that we can use to prevent cyber-attack. OWASP Security Shepherd can be used as a way to prevent XSS attacks. The OWASP Security Shepherd project allows users to learn or develop their manual penetration testing skills. In this research, there are several case examples or challenges that we can use as a simulation of the role of OWASP Security Shepherd to detect this XSS. The purpose of this paper is to conduct a brief and clear review of technology on OWASP Security Shepherd. This technology was chosen as an appropriate and inexpensive alternative for users to ward off XSS attacks.

Decreasing customers of motorcycle workshop and to respond the situation bring up the idea to reengineering business model. Home service system was selected as alternative solution to strive for survive in this situation, of course, by implementing a good health protocol. This system was built with a mobile application as a tool in reservation and managing customers service schedules. With this system customers do not have to come and queue at the workshop, so it will be safer in this pandemic situation. Not all services can be served with this system, only minor, moderate and routine repairs that can be served with this system. The payment transaction process is carried out on the spot according to the calculations by the system. With this new business process model, it is hoped that it will be the right solution for consumers and workshops so that they can remain productive in the midst of the Covid 19 pandemic.

Abstract

Knowledge gap among students is one of the challenges in teaching-learning process. Active learning can be one possible way to the solution, as study shows that active learning increase students’ achievement. Knowledge transfer between peers can have its place in an active class, since group discussion is part of the class design. We have been applying active learning in our classes where students were invited to teach in small groups or in class. In this paper we share about our experience in designing and implementing active learning strategies in our classes. After witnessing students’ success through active learning, we conducted a study to gain students feedbacks about the positive impacts of the active learning to their understanding of the teaching material. Thirty-six students fill out the questionnaire in Google Form anonymously. The result shows that our class settings that employ active learning increases students’ understanding of the teaching materials and hence, students’ grade. Over 93% give positive feedback about our class design and implementation. Students also give positive feedback about our personalized teaching and personal approach during the group activity in our classes. We conclude that class designs which incorporate active learning, is beneficial for students to increase their understanding of the teaching materials.

Abstract

Bananas that ripen with chemical process or do not ripen naturally usually, this can be recognized by the presence of blackish patches on the surface of the skin. But visual recognition has its drawbacks, which is that it is difficult to recognize similarities between formalin bananas and natural bananas, resulting in a lack of accurate identification. In this study, a system was built that can determined formalin bananas and natural bananas through digital image identification using supervised classification. The image to be identification previously goes through the process of transforming RGB (Red Green Blue) color to Grayscale, and the process of extracting texture features using statically recognizable features through histograms, in the form of average, standard deviation, skewness, kurtosis, energy, entropy and smoothness. The extraction of texture features is classified with LVQ (Learning Vector Quantization) to determine formalin or natural bananas. The test was conducted with 122 banana imagery sample data, 100 imagery as training data consisting of 50 imagery for natural bananas and 50 imagery for bananas formalin, 22 imagery as test data. The test results showed LVQ method has the best percentage at Learning Rate 0.1, Decreased Learning Rate 0.75 and maximum epoch of 1000 with the smallest epoch of 7, obtained accuracy 90.90%, precision 84.61% and recall 100%.
