The window is one of the most important aspects of a building. It aims to obtain good lighting and meet the requirements for Indoor Air Quality. A restroom is a place where most surfaces are wet, and it causes the relative humidity to become high. As a result, lighting must be considered in this space. The men’s toilet on the second floor of the Bina Nusantara University campus in Malang is the subject of this research. Interviews with building operators, cleaners and firsthand surveys of the location were also undertaken. The author used the results of interviews to help specify the ventilation system. The author utilizes a lux meter to measure the lighting layout. According to the findings, this toilet uses mechanical ventilation in the form of an exhaust fan. On the other hand, this area employs downlights that meet lighting standards in terms of brightness and color temperature selection in the artificial lighting system. In the current situation, there is a shortage of energy efficiency. As a result, this study offers a method for preserving electrical energy. This study uses an Arduino Mega and several sensors to help automate the operation of these electrical devices.

Cafe interior design that supports health protocols in new normal conditions will be essential to keep cafes safe to visit. In this new-normal era, the implementation of good circulation for public areas is critical and has become one of the main concerns of cafe visitors. Good circulation is one aspect of the eco- interior concept that existed before the pandemic. Eco-interior is an interior building concept that emphasizes sustainability and the reciprocal relationship between humans and the surrounding environment. This study aims to determine the considerations of visitors in choosing an indoor or outdoor café to be visited in the new-normal era. The case study that will be analyzed is a cafe in Malang City, which is still in demand by visitors in the new-normal period. The research method used is descriptive qualitative. Research data were obtained through field studies, interviews and questionnaires. As a result, most visitors choose to visit cafes with outdoor or semi-outdoor areas with smooth air circulation compared to cafes in indoor spaces. From the analysis results based on the eco interior parameters, the application of ventilation in the café is at the ideal stage, while the pollution control in the café area is a substantial effort.

Practical learning in the laboratory has been limited due to the COVID-19 pandemic. Conventional education must adapt to increasingly digital technological developments. The design of interactive learning media with augmented reality technology can be a solution and support the previous conventional learning. FunAR is a Furniture Augmented Reality Application developed using the analysis, design, development, implementation, and evaluation (ADDIE) method consisting of ADDIE. In its implementation, the FunAR application will provide basic information about existing equipment in Lab Furniture, accompanied by 2D images, and augmented reality technology that creates 3D objects from each piece of equipment in Lab Furniture. From 15 student respondents, the results reveal that distance, angle, and device specifications significantly impact camera marker reading. A distance of 20 cm to 80 cm and an angle of 25° to 100° can display 3D objects. Likewise, the camera's ability to process reading markers is better on smartphones with better hardware specifications. The results of the respondents showed that 80% of respondents were satisfied with the FunAR application. [ABSTRACT FROM AUTHOR]
