Increasing human productivity accompanied by increasingly advanced developments has an impact on the need for faster and easier communication and data exchange, one of which is using a mobile smartphone. ReResik application is an application that is used to report the accumulation of garbage. Garbage accumulation is a problem that is often encountered, one of which is in Gunungkidul tourism objects, so there needs to be a solution to solve this problem. One solution is to utilize Global Positioning System (GPS) and Firebase technology to create a waste reporting application. The use of GPS can make it easier to report the accumulation of garbage in a place by utilizing geo tagging technology and the complexity of the features found in Firebase provide user convenience both in terms of application development and the use of features in applications that can facilitate reporting and recipients of waste reports. All functions in the ReResik Application run according to design. Tests in the field can show the location of the accumulation of waste with photos sent with the difference in the accuracy of the location where the report of accumulation of waste occurs 1.38 meters from the location point sent by the application. The average data transfer capability of the ReResik Application upload is 1161.8 ms for the reporting section and 1004.2 ms for the cleaning staff. Functional testing of photos uploaded to Firebase has gone through the process of automatically compressing photos with an average value percentage of 61.22% of the uploaded photo size.

The Glider Eagle-X aircraft is an unmanned aircraft which is expected to fly with a height of 7 meters above the ground in Yogyakarta (120 m above sea level) with a flying speed of 10 m/s. In order for the Eagle-X glider to fly stably, it is necessary to analyze the flight stability of the Eagle-X glider model. Therefore, in this study, the analysis phase of static stability and dynamic response of disturbances in the longitudinal dimension was carried out. This can be useful for students so that they can better understand the analysis of static stability and dynamic response of disturbances in the longitudinal dimension. The results of the analysis show that the flight dynamics is a value of CM-α < 0 indicating the plane is statically longitudinal and the initial response of the graph is getting smaller which indicates the plane's motion is dynamically stable. The output of the stability analysis of the flying dynamics of the Eagle-X glider model is in the form of a graph. The simulation of the flying dynamics of the Eagle-X glider in the expected longitudinal dimension is shown by the aircraft movement following the graph from the results of the stability analysis which is used as the path of the Eagle-X glider model.

The technology that can be developed from Unmanned Aerial Vehicle (UAV) in agriculture is the Unmanned Aerial Vehicle Eagle-X. This technology can help farmers in carrying out their daily activities to repel bird pests on agricultural land. However, people have difficulty understanding how to use UAVs. So, with this simulation, it is hoped that it can help farmers and producers understand the workings of the eagle-x aircraft. The simulation is made using 3Ds Max software which functions to create all 3D objects and also uses Unity software to create animations and simulations. This simulation can run well on a PC or laptop that has a Windows 10 operating system with 64bit and a minimum of core i-3 specifications. Trials using simulations were carried out on 30 farmers and the results showed that 86.67% of farmers stated that this simulation was effective in providing an overview of how the Unmanned Aerial Vehicle Eagle-X works in repelling sparrow pests.

In today's data-driven business landscape, the analysis of big data has become a pivotal tool for making informed decisions across industries. This research method paper explores the methodologies employed in big data analysis for business decision-making and conducts a bibliometric analysis using VOSviewer to map the scholarly landscape of this field. The systematic literature review identifies key methodologies, including descriptive, predictive, and prescriptive analytics, text analysis, and network analysis. Real-world case studies demonstrate their practical applications in diverse sectors such as retail, finance, healthcare, and more. The bibliometric analysis unveils influential authors, collaborative networks, research clusters, and trends within the academic discourse on big data analysis and business decision-making. By integrating empirical research, systematic review, and bibliometric analysis, this paper offers a comprehensive understanding of the role of big data analysis in shaping contemporary business decisions.
