The Level of Thermal Comfort in Residential Houses Based on the Shape, Orientation and Material of Roof Cover in Kampong (Case Study: RT.05/RW.04, Kamal, Kalideres, Jakarta Barat)

—Kampung Kota (KK) is a form of urban area settlement in Indonesia. KK is a characteristic of big cities that still carry the environment and behavior of rural life, dense buildings, densely populated. Also, urban villages are characterized by low per capita income, developing without regular patterns. In terms of physical comfort, houses in urban villages are generally not by thermal and visual (light) comfort requirements. RT.05 / RW.04 Kamal Village, Kalideres District, West Jakarta, is one of the most problematic urban villages in DKI Jakarta. One of the problems at the location (RT.05/RW.04) is thermal comfort, which is under the standards (SNI T-14-1993-037). For this reason, this research is needed. This study is conducted to measure the level of thermal comfort in residential homes in RT.05/RW.04. Measurements were made based on the shape, orientation, and material of the roof covering. The roof was chosen as a benchmark because the roof is one of the media for the entry of solar radiation into the building. The purpose of this study was to determine the level of thermal comfort in households in KK based on the shape, orientation and material of the roof covering. This research uses a quantitative method with an experimental approach. The quantitative method is done by grouping the house based on the shape, orientation, and material of the roof. Then each house's thermal comfort level is measured. The measurement results are used to determine the effect of the shape, orientation, and material of the roof covering the thermal comfort level of households in KK. The results of this study are the recommendation of the shed roof to absorb less heat than the hip and gable roof. The orientation of the roof facing west and east absorbs less heat than the orientation of the north and south roofs. Clay tile roof covering material absorbs less heat than the asbestos material.
