In the changing times from year to year the development process is always progressing. No exception to the construction of settlements and housing scattered in the city of Surabaya. Arrangement of a housing environment is an important factor in improving the quality of life of residents in society. The residential space pattern in Babatan Pilang still maintains the brandgang system. The function of this brandgang itself is as a fire breaker to slow down or stop fires. Apart from the two main functions, brandgang indirectly also acts as a connection path between alleys or roads. The existing condition of the brandgang in the Babatan Pilang housing complex is not neat and well maintained. In general, the brandgang should not present a tense and frightening atmosphere. The method used is extracting data again looking at the aspects of the problems that exist in relation to the existence of brandgang so far. The function and role of brandgang wherever good and their existence are not necessarily forgotten and are more important, this is because brandgang is one of the main factors of a security system in a settlement or housing. Presenting a neat and orderly brandgang will create a good impression in restoring its main function.

Residents of RT.02 RT.003 Asempayung, in general, are indigenous people who have lived in the area for generations. The rapid development of the population has resulted in the narrowing of residential land because it has been divided among the heirs of children and grandchildren.The limited open land has resulted in several community activities being carried out on environmental roads. The Abdimas empowered the community to participate in mutual cooperation in completing the program. UKDC Architecture Study Program will carry out an activity program for the expansion of the community activity center in 2022 by: 1) Empowering the community to participate in the expansion of the activity center; 2) Together with the residents, they will procure sewer cover material as an expansion of the community's activity center. This is largely determined through good communication, social approaches and intense interaction with residents. The output obtained from this community service program is the expansion of the activity center for the residents of Asempayung RT.02 RW.003. This activity will cover the sewerage of dirty water which is about 2.5 meters wide. Closing the channel will form a space above it, which can be used as a center for residents' activities.

The area of open land in the City of Surabaya is decreasing from year to year. This is influenced by the number of settlements and housing that have begun to emerge and develop, thus increasing the population level in an area. Humans are by nature social creatures. Can not be separated from other individuals and need each other. Individual someone indirectly lives together with the surrounding environment. This is what triggers that each individual must be social to one another. However, along with the times and technological advances today, many individuals often forget this and think more about their respective interests. Time to gather and meet face to face with neighbors, chat with each other directly or with the surrounding environment is also very minimal. Broadly speaking, the Babatan Pilang community is individual. The background to the problems that have been previously described is the basis for this community service to be able to provide input to the community of Babatan Pilang RT. 003 RW 005. The purpose of this community service is to help the community or housing residents to restore and create a social society. This community service program is carried out by creating and arranging common spaces for socializing.

Indonesia merupakan negara yang memiliki begitu banyak warisan budaya yang terlahir dari masa prasejarah. Peninggalan secara fisik yang ada saat ini banyak berupa bangunan candi. Candi sendiri memiliki fungsi utama pada zamannya sebagai tempat persembahyangan kepada dewa ataupun sebagai istana suatu kerajaan. Candi yang ada berasal dari peradaban kelahiran dan penyebaran agama Hindu dan Buddha di Nusantara. Kedua agama ini menjadi agama tertua dan yang pertama kali masuk ke Indonesia. Candi di Indonesia sendiri paling banyak berada di Pulau Jawa tepatnya di provinsi Jawa Tengah dan Jawa Timur. Lokasi tempat terbangun dan berdirinya candi dikedua provinsi ini disesuaikan dengan jarak sumber untuk material utamanya. Hal ini dikarenakan kondisi lingkungan geografis tempat berdirinya lokasi candi-candi tersebut yang berbeda-beda. Metode yang digunakan dalam penelitian ini adalah dengan komparatif membandingkan data yang didapat antara candi yang berada di Jawa Timur dan Jawa Tengah didasarkan letak geografisnya. Hasil yang diharapkan yaitu dapat mengetahui lebih jelas penggunaan material batuan candi yang didasarkan pada letak, jarak dan kondisi geografis dari sumber utama bahan batuannya. Umumnya jenis material utama batuan yang digunakan untuk pembangunan candi dikedua provinsi ini dikaitkan karena kedekatan dengan sumber material dan lokasi terbangunnya candi.
