The use of packaged detergent that produce B3 waste is still unknown by the residents. In addition, the absence of waste management and particular disposal systems also contribute as a negative impact on the environment. The training and socialization activities for making environmentally friendly detergents were carried out to provide information about the basic ingredients for eco-friendly detergent using Methyl Ester Sulfonate (MES) as a vegetable surfactant, as well as to encourage participants to be able to make detergents independently. The method used in this activity is demonstrations by explaining the stages of manufacture. The process of making detergent is carried out through the preparation stage, the making process and recording in video, using simple tools and materials. Video demonstrations were published on social media so that the dissemination of information was wider than the initial target of the activity. Through this activity, the results obtained were that the stages of making detergents that were not too complicated, so it could be easily understood, especially with a video guide that could be accessed at any time.

Old town means an historic or original core of a city which signifies the city’s origin growth. When the city develops and expands its built area, the emergence of a new development center will be inevitable. This study focuses on the connection of the old and new development center of Balikpapan city. In defining the mentioned connection, the authors use Space Syntax theory and depthmapX[net] software to analyze connectivity, integration and choice of the observed networks. Space Syntax analyses helped defining the spatial configuration of the old and the new center of development of Balikpapan city which has higher scores in main connectors and lower scores in local streets which also defines the movement and accessibility of the observed area. It is hoped that this study would be beneficial in guiding the planning and design of the future development of Balikpapan city that is appropriate with its spatial configuration.

Pemaknaan ruang menjadi salah satu aspek keberhasilan ruang publik yang ditandai dengan terciptanya interaksi sosial antar pengguna ruang. Kepastian interaksi sosial pada kawasan permukiman sebagai ruang tempat tinggal dengan kedekatan dan kepadatan yang relatif tinggi dapat mendukung vitalitas area perkotaan. Tujuan penelitian adalah menganalisis hubungan antara pembentukan ruang publik dan aktivitas masyarakat atau komunitas, khususnya pada permukiman tepi sungai. Metode penelitian kualitatif digunakan untuk mendapatkan gambaran nyata keadaan di dalam ruang publik berdasarkan interpretasi observasi langsung. Pengamatan peneliti didasarkan pada kajian pustaka yang dilakukan terhadap pustaka tentang ruang terbuka dan perilaku masyarakat dalam ruang publik yang relevan.  Sebagai bagian dari proses pemahaman fakta di lapangan, teknik survei terbuka dilakukan pada tiga ruang terbuka di kawasan permukiman Manggar untuk mengetahui pola aktivitas pengguna ruang dalam hal penetration, action pattern, behavior mechanisms, dan welfare. Hasil penelitian menunjukkan bahwa ruang terbuka publik terbentuk melalui aktivitas rutin masyarakat secara alami, melalui proses pemilihan tempat yang berdekatan dengan akses pekerjaan.

Online learning is a method used by schools during the COVID-19 pandemic to anticipate and avoid the spread of disease among students. In practice, there are advantages and disadvantages of online learning that are felt by both students and parents.

The presence of open spaces in the spatial order of the campus can encourage students to engage in outdoor activities aimed at improving their quality of life and academic performance. Providing an integrated, open campus space is the key to creating a unique, dynamic, and aesthetic campus. During development, Institut Teknologi Kalimantan (ITK) continues to develop the infrastructure to support all lecture events, one of which is an open space configuration for College Building E. The landscape design process for this college building is in progress. It consists of five steps consisting of (1) problem identification; (2) data collection; (3) data analysis; (4) formulation of concepts; and (5) Design. The landscape design concept of College Building E conceptually applies the principle of multifunctional space as seen in the design of public green open spaces that combine the functions of public and green spaces. The coexistence of public and green spaces creates harmony in the design of educational, recreational, interactive, aesthetic, and dynamic open spaces.
