A healthy and sustainable indoor space was one of the goals of a building, which was an important concern of architects in designing and using it. Design arrangements can be approached physically, such as the use of air vents, lighting, and layout arrangements. However, now the paradigm of using a natural approach has been intensive. In this regard, this paper focuses on the greening of indoor spaces, both for the prevention and restoration of indoor room quality. The study methodology was a survey of existing research results in many countries, and a selection of up-to-date, current data. The results of the literature research obtained are related to the purpose of indoor greening, which is none other than to achieve the goal of green building. Its main target was biodiversity in the prevention of negative health effects and indoor phytoremediation.

Indoor quality is an important and necessary concern towards indoor use, which sustains the health of the occupants. Indoor health is the resultant of exposure to all building materials, the contents of room equipment, occupant activities, and the ability of the space to eliminate negative effects on life. This paper adequately describes sources of pollutant exposure, pollutant movement, biological processes, health impacts, all of which can cause Sick Building Syndrome (SBS). Furthermore, indoor depollution measures to counteract SBS need to be carried out at the stages of building design and construction. Based on the interests and needs, here it is necessary to propose a certification of potential SBS at the design and construction stages. Thus, SBS responsibilities can be proportionately distributed to designers, contractors, and building users.

Introduction: Indoor bioaerosol is one of the factors of sick building syndrome that needs to be controlled for the health of building occupants. Control of bioaerosols is a daily obligation for occupants, but can be alleviated through a building design approach, so that the potential negative effects of bioaerosols are minimized. This study aims to fill the criteria for controlling bioaerosols at the building design stage, in addition to the operational use of the building. Methods: This literature study on indoor bioaerosols uses the Mendeley Reference Manager platform with the search phrase indoor bioaerosols. The selection of literature based on open access journals, in English, excluded the indoor production process. Results: In the perspective of the building infrastructure design, the ventilation system is an opening facility between indoor and outdoor, as a mechanism for air flow and quality balance between the two spaces. The implementation can be in the form of fixed openings in walls, openings that can be opened and closed manually or mechanically, including windows and doors. Effective reduction of bioaerosol concentration needs to sit up the type of ventilation that is adapted to the function of indoor use and occupancy load. The ventilation method is supported by a chemical method, which is appropriate for control in food service rooms and sanitation services. Conclusion: The bioaerosol control strategy can start from the design of the building by the designer and continue to the implementation and maintenance of the building by the occupants.

Trunojoyo Park in Malang City is one of the city parks that has a predicate as the best park. The government of Malang city supports this park into a city park that must be visited by the tourists. The problem is trunojoyo park requires a direction of future development by looking at the perception of visitors who visit the park. The purpose of this study is to know the direction of the new design to find the appropriate design criteria in relation to one's response from the perceptions seen. The architectural intervention in the landscape is one way of approaching how to view the perception in the realm of architectural design. In two ways: temporary intervention and permanent intervention, this method looks at how one's response perceives the architectural element as an aesthetic element in which there is an Islamic ornament as one of the objects applied. This study used descriptive research through field observations by giving random questionnaires that were divided into men and women. Analysis and discussion are done by sorting and calculating each variable of choice of the respondent quantitative). They were further evaluated to determine the factors of visitor perception assessment of aesthetics Park City. This study shows that the order and diversity of vegetation, completeness of facilities, security, and comfort of the Park City are the factors of assessment of visitors to the aesthetics of the Park City. This research has benefited from the emergence of new theories regarding the visitor's assessment of the aesthetic City Park.

Hasanuddin University Lake in Indonesia is a water tourism destination that offers natural beauty and comfort. In addition, the lake functions as an important scientific development park for the university. Even though its location is on campus, the surroundings of the campus are residential areas and various life activities. Recently, weed growth has occurred, which could be an indication of contamination and may hinder its useful function. Therefore, this study investigates the physicochemical quality of water, the pollution index, and its monitoring, attempting to make the campus lake continue to function sustainably. The research was carried out at the peak of the dry and rainy seasons, with laboratory examinations based on standard methods for quality parameters that follow lake use function standards. The results showed that most of the water quality parameters measured needed to meet the required quality standards. Based on the scoring results using the water pollution index method, lake water is classified as lightly to moderately polluted, which requires protection. The monitoring method is prepared with the addition of a biological indicator system. In line with that, intensification of the diversity of greenery around the lake and environmental management in an integrated manner with the surrounding settlement. The conclusion is that there is a need for complementary monitoring between physicochemical and biological methods and management coordination with the surrounding territories.

This paper discussed a new perspective on the path of sunlight as a basis for urban phytoarchitecture design, which empowers the ability of plants to absorb carbon dioxide and simultaneously lowers the surface temperature. The aim was to provide options for intensifying greenspace orientation and plant types as one of the goals of a sustainable city. This research analysed previous research sources collected from the reference management platform. The literature selection uses the keywords greenspace, orientation, carbon dioxide, and surface warming, all of which are the latest publications. The result for the first option was the orientation of the greenspace following the path of sunlight. For urban infrastructure in a North-South direction, it was advisable to intensify greenspace by planting trees that absorb large amounts of carbon dioxide. In addition, it was recommended to apply biodiversity to enhance the absorption of the gas. For East-West oriented infrastructure sites, intensifying greenspace with sunshade trees was the right choice, and biodiversity was not a limiting factor because it does not support leaf area growth. While the first option cannot be followed due to existing field conditions, the second option is intensifying tree species with biodiversity, which can absorb carbon dioxide and reduce surface warming.
