The Orang Dalam Pengawasan (ODP) and Pasien Dalam Pegawasan (PDP) Covid-19 monitoring system in the Health Service task force in Dago area is a system that monitors and records people who are indicated to be affected by the Covid-19 disease. Orang dalam Pengawasan means “people under monitoring” in Bahasa Indonesia while Pasien dalam Pegawasan means “patients under surveillance”. To support the ODP and PDP Covid-19 monitoring system, an application is needed that can assist in the monitoring process in the Health Office task force in the Dago area through the utilization of Android-based technology. This research aims to help the task force not be late in reporting the number of ODP and PDP to the Government of West Java Province. Moreover, it also aims to avoid differences for data between the public health center and the Health Service task force in the Dago area so that the results of this study are in the form of information about the total findings and monitoring of ODP and PDP Covid-19 every day through the Android application. This research used a descriptive qualitative method. The results show that the application could help the task force in reporting the number of ODP and PDP to West Java Province. In the ongoing system, when carrying out the monitoring process, the task force always contacts the health centers in Dago via telephone or WhatsApp for the data collection and reporting process to not be well computerized. It causes delays in reporting data to West Java Province. Problems also occurred with the amount of data due to the absence of a data closing system, which resulted in reports on the number of daily ODP and PDP Covid-19 data that were always differences between the public health center and the Health Office. In conclusion, this information system could help the reporting process.

Tired with routine urban activities, triggering the development of nature tourism as a place of recreation that is most in demand. Therefore, this research was conducted to determine the role of community participation and land-use change in the Kampoeng Ciherang Tourism Area, to realize sustainable tourism management in the Covid-19 pandemic. The method used in this research was data collection using primary and secondary data, by directly observing the current conditions of Kampoeng Ciherang Tourism Area, which was supported by the availability of secondary data from the relevant agencies. This research discussed community participation in the management of Kampoeng Ciherang Tourism Area, and the impact on land use from tourism activities, especially during the Covid-19 pandemic. The results of this study indicated that in managing tourism, the Tourism Area of Kampung Ciherang had not been able to realize sustainable tourism management especially during the Covid-19 pandemic period, this could be seen from the low level of community participation because tourism management was still fully held by the private sector as the owner of facilities and infrastructure and government as supervisors, even though the change in land use did not experience significant changes at the tourist site. If it does not pay attention to sustainable tourism management, it is feared that in the future there will be an uncontrolled conversion of land from these activities.<strong></strong></p>
