The level of the spread of covid-19, which is still high in the city of Semarang, indicates the low level of public awareness in complying with health protocols. The role of urban open space in Semarang City needs to be optimized to support this effort by adding several facilities that did not exist before the pandemic, so that people comply with health protocols, wear masks, wash their hands frequently and maintain physical distance when carrying out their social activities. The aim of this study is to determine how to optimize the role of public open space in supporting efforts to maintain the health of urban communities based on public awareness in complying with health protocols when doing activities. The research was conducted in three open spaces in Semarang, Indonesia, using survey methods and a descriptive qualitative analysis by observing the physical condition of the park, the behavior of the people in doing their activities, and park management officers. The results show that the three locations are now equipped with supporting facilities, but they are less effective in forcing people to remain obedient when doing activities. The level of public awareness and compliance has not met expectations and most of the people are still ignorant. Therefore, there is still a need to add more attractive and more massive facilities and to give more socialisations so that urban open spaces can be safe and healthy locations to visit as well as to play a more optimal role in improving people's physical and mental health during the pandemic

Aliran air yang mengalir dalam tanah yang memiliki butiran halus, cenderung mengangkut butiran halus tersebut. Taman PAUD Edelweis yang menerapkan bata KOBEL sebagai penutup permukaan tanahnya sekitar kolam, mengalami ambles saat hujan lebat, karena air hujan meresap ke tanah dan mengalir membawa butiran halus menuju kolam. Masalah ini mendorong untuk diterapkannya bata KOBEL juga guna memperbaiki tanah yang ambles akibat aliran air tersebut. Kegiatan pengabdian masyarakat di Dusun Serut, Palbapang, Bantul, Yogyakarta ini bertujuan untuk mendampinginya dalam menerapkan bata KOBEL mengatasi permasalahan tanah ambles. Metode pelaksanaan kegiatan diawali dengan survei lapangan, kemudian pendampingan cara menyusun bata KOBEL dalam mengatasi amblesnya tanah. Bata KOBEL memiliki 2 lubang berdiameter 5 cm, disusun membentuk suatu pipa yang berfungsi mengatur aliran air sehingga tidak membawa butiran halus mengalir/tererosi. Konsep sederhana menyediakan alur aliran air, dapat menghindarkan erosi yang terjadi sehingga tidak menimbulkan amblesnya tanah. Bata KOBEL ini terbuat dari tanah yang dipres sampai 62,5% berfungsi sebagai perbaikan tanah, sehingga permukaan tanah menjadi stabil. Penggunaan bata KOBEL mudah dilakukan dan biayanya sangat murah, dapat menyelesaikan masalah yang dihadapi masyarakat Dusun Serut.
