Understanding COVID-19 Effects on Mobility: A Community-Engaged Approach

Abstract. Given aggregated mobile device data, the goal is to understand the impact of COVID-19 policy interventions on mobility. This problem is vital due to important societal use cases, such as safely reopening the economy. Challenges include understanding and interpreting questions of interest to policymakers, cross-jurisdictional variability in choice and time of interventions, the large data volume, and unknown sampling bias. The related work has explored the COVID-19 impact on travel distance, time spent at home, and the number of visitors at different points of interest. However, many policymakers are interested in long-duration visits to high-risk business categories and understanding the spatial selection bias to interpret summary reports. We provide an Entity Relationship diagram, system architecture, and implementation to support queries on long-duration visits in addition to fine resolution device count maps to understand spatial bias. We closely collaborated with policymakers to derive the system requirements and evaluate the system components, the summary reports, and visualizations.

Metode Prototype pada Sistem Informasi Manajemen Tugas Akhir Mahasiswa Berbasis Website

Final Project as a Research is one of the main requirements for the graduation of undergraduate students from universities. Supervisory guidance is one way to find solution for student research problems. The final project guidance process involves multiple parts: campus administration, supervisors, and students. However, this process is often difficult to carry out properly because of the busyness of each individual, both lecturers and students. As a result, the process for carrying out the final project was hindered. Another thing that makes the completion of the thesis slow is the administrative service procedure to complete the final project which is too time consuming. This research aims to simplify and speed up the process of completing the student's final project. The prototype method is used to develop the final project management information system. This information system is designed using use case diagrams, rich picture diagrams, and entity relation diagrams. Tests were carried out using the black box method. The result of the research is a final project management information system which makes the student's final project completion process more efficient and effective. This information system facilitates administrative services and monitoring of the final project because it is performed systematically and can be controlled in real time.

Web-Based Tourism Decision Support Information System

Tourism is one of the potential resources that can be developed by each region. As one of the resources that generate foreign exchange for the country, this requires optimization in the provision of services to further support the potential of tourist areas to be visited. When this study was conducted, tourism in bangkok has used internet media in promotion. However, the system used is still not perfect. This problem comes from poor tourism data management and still not maximal some facilities in the running system. With some of these problems, it is time for the old system to be fixed.

In this study, the research method used is descriptive and action research, while the system approach used is structured with the method of system development using waterfall model. The tools used are context Diagram, data Flow Diagram (DFD), Data Dictionary, and Entity Relationship Diagram (ERD). Database design tools in the development of this information system is the normalization and table relation. The programming language used is PHP, with Adobe Dreamwaver CS5 tools. For the database, This Information System uses MySQL and for decision making, this information system uses the AHP (Analitycal Hierarchy Process) method with the creation of this information system, the author hopes that the information system that the author makes in the future can improve the quality of service for tourists and can help top tourism management in Bangkok to make decisions.

RFID Implementation on Information Recording Systems of Deer

Deer are animals that currently still have conservation status as protected animals. However, for the activities of breeding and caring for deer animals, they are allowed and given legal payment by the government. However, in practice, there is still a lot of illegal deer meat or the result of illegal hunting which is also sold in the Indonesian market. Recording of deer seed genealogy and legality of breeding is one way to differentiate between illegal and legal deer meat sellers. However, due to the manual form of recording, human errors often lead to errors in recording. Therefore we need an application that can handle manual recording coupled with the implementation of RFID on meat so that it is expected to facilitate the existing recording process. The purpose of this research is to create a deer recording system application that can assist users in making sales and purchasing transactions as well as checking the lineage of deer seeds using the implementation of RFID. The method applied is through the design of Use Case Diagrams, Entity Relationship Diagrams, flowcharts, and using the Laravel 7 framework with the application of MVC to produce a Deer Recording System (SRS) application aimed at helping breeders. After the application was generated, testing was carried out on 84 buyers and prospective buyers of deer meat in deer breeding in Kudus, and the results showed that the EE (convenience) and FC (facilities) variables had a significant correlation with the BI variable (desire to return).

Analisis Teknik Entity-Relationship Diagram dalam Perancangan Database Sebuah Literature Review

There are many techniques used in database design. One of them is entity relationship diagram technique. ERD is one of the main diagrammatic representations of the conceptual data model that reflects the data requirements of users in a database system. ERD is also the first stage in database design. There are several things that must be considered in making an ERD for database design including, each database must have entities that are interconnected by relationships and each entity must have attributes consisting of a primary key as a characteristic of the entity and descriptive attributes. Many users have failed to create a database due to errors in the ERD creation. These errors can be conceptual errors, procedural errors, or technical errors. Therefore, this paper was made using the SLR method, namely by reviewing various kinds of references that discuss database design and then drawing conclusions, to make it easier for users to overcome problems that occur when making ERD and when implementing it.
