Published: 2023-07-29 AbstractAi Sukabumi is one of the West Java Province regions with the potential for forest resources.
The lack of renewal in the way data is processed has led to the need to develop information systems for mapping potential forest resources focused on the Sukabumi region.
In doing so, the development of the system will help the government manage forest resources more efficiently.
In the system development process, the Y-Model Framework of Web-GIS Development is used as a development method that is a combination of waterfall and agile approaches followed by 4 phases, with a combination of geographic information system engineering with the help of ArcGIS as a tool for mapping and web-based application development contexts.
At the development stage, it was also built using text-to-speech technology to provide voice capabilities for the information displayed.
The development of web-based GIS applications will help facilitate access to information about potential forest resources in the Sukabumi region for the community and related parties.
The results of the development of this system are visualized in the form of maps based on the Geographic Information System (GIS) and presented online through a web application.
The success of using the Y-Model framework in the development of this system is demonstrated in the User Acceptance Test (UAT) test results through a questionnaire instrument distributed to respondents with an average value obtained above 82%, which shows the level of user satisfaction with the system has been well received and shows that the application has met the needs of the user.

Sukabumi had a people's forest of 78,963,28 Ha, accounting for 18% of the administrative territory of Sukabumi, most of which was spread across the territory and also the city forest of 204,4 Ha, counting for 0,048% of the administrative area of Sukabumi, spread over the district and the city.
In addition to the fairly potential forest area, the Sukabumi region has the potential for diverse forest resources, both in the form of forest .

tourism and environmental services.
Based on the ground check data of the field in 2022, there are 128 forest farm groups spread across the territory of Sukabumi, including SDH potential such as wood forest output production of 59.
110,96 m3.
HHBK production such as honey of 275 stop produced 615 kg, wood fungus production of 370,000 log produced 186,615 kg.
At present, the problem found mainly regarding the collection of potential data SDH that exists in the region of Sukabumi among them is the potential SDH has not been fully inventoried, so that the mapping and presentation of the potential data of SDH become impaired.
Then in terms of technology, there is an emergency fund that is needed for application for data processing about the potential of SDH that can bridge the interaction of other users internally due to the existing information system has not met the needs of the user because of the lack of space to load and data on the potential for forest resources.
Some input and coding subsystems must be improved upon existing systems to produce new outputs.
This research aims to develop a text-to-speech technology based interactive geographic information system (Web-GIS).

CONCLUSION
Implementing the Y-Model Framework in the development of information systems for mapping potential for forest resources in the Sukabumi region is an effective approach to new innovations in mapping.
To date.
Web-GIS is the most appropriate application for the speed of obtaining data and aggregate information, spatial and non-spatial, as well as accuracy in the data input process.
The YDWM methodology is implemented in five stages, i.
, phase 1 includes planning and formulation of materials, phase 2 analysis of functional and non-functional needs.
Phase 3 makes geospatial database design and web navigation, phase 4 performs acquisition of geospatial data of web construction, the final stage is integration and management.
The results of implementing the YDWM methodology in this study are characterized by developing the new interface pages, mainly in the map menu.
From the data that has been obtained and processed into a GIS, it can be seen that the data on potential forest resources in Sukabumi includes the distribution of potential non-timber forest products, the distribution of industrial timber, the distribution of potential environmental services, and the distribution of natural tourism potential in the Sukabumi region.
And from the results of testing applications made through questionnaire instruments distributed to respondents, an average value of above 82% is obtained.
This indicates that user satisfaction with the system has been well received and the application has met user needs.
The development of this system is expected to be a new innovation in the management of geospatial data and information on related agencies.
