Pengaruh Bentuk Bukaan Atap Bangunan Terhadap Tingkat Kenyamanan Termal Pada Rumah Panjang Suku Dayak Brusu, Kecamatan Sekatak, Kalimantan Utara

Abstract

The long house of the Brusu Dayak tribe that lives in North Kalimantan is a house that always increases the length of the building following the increase in the number of family heads in one offspring. The most interesting part of the longhouse compared to other Dayak tribes' houses is that in the longhouse Brusu Dayak tribes do not have windows but only rely on openings on the roof of the building according to their residential needs so that it affects the thermal comfort of the longhouse. In general, this study aims to determine the effect of the shape of openings on the roofs of Dayak Brusu tribal longhouse buildings on thermal comfort levels. The research method includes direct surveys to the field by observing the shape of the building and the shape of the roof opening in the longhouse, as well as doing direct measurements on several points determined. Measurements made include measurements of temperature, humidity, air movement, where measurements are made on the interior of a long house with 15 measuring points, where each point is measured for 24 hours with the time of measurement every 2 hours. From the above analysis, it can be concluded that the effective temperature for the tenang area is more likely to be lower than the ganak and lamin, this is because the roof formation of the long house located in the garden can be opened and closed according to the needs of the occupants.

Energy Conservation Techniques in Tropical Climate - A Comprehensive Review and Adaptation of the Lamin House for Nusantara

“…In Lamin's house, the roof serves as an element that dominates the house. The research found that the roof maximized heat transfer, as in the Brusu Dayak tribe living in North Kalimantan 22) and Betang Ensaid Panjang, the traditional Dayak house in Sintang Regency 23) . A research method includes direct surveys and measurements of several points in a traditional house, including measurements of temperature, humidity, and air movement 22,23) .…”

“…The thermal comfort of Lamin houses varies at different times in different spaces 22,23) . As a result, it can be classified as slightly cool in the morning, warm in the afternoon and evening, and comfortable at night.…”

“…As a result, it can be classified as slightly cool in the morning, warm in the afternoon and evening, and comfortable at night. Since solar radiation can enter directly through the roof gaps, causing air temperature and wind movement to change 22) . Other building components affect heat transfer and air movement as well.…”

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)

“…While the experimental approach is carried out by measuring air temperature and humidity based on the group shape, orientation, and roof material. 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 [7] dan [8].…”

Karakteristik Termal Rumah Suku Dayak di Kalimantan Tengah (Studi Kasus: Rumah Betang Buntoi, Rumah Betang Toyoi, dan Rumah Betang di TMII)

“…Hal ini diterapkan pada rumah mereka yang disebut rumah Betang, dan rumah ini memiliki konsep persatuan didalam setiap keluarga yang harus terwujud agar dapat bertahan dari serangan musuh. Bentuk rumah yang sederhana tanpa memiliki bukaan atau ventilasi berupa jendela, rumah disampingnya sebagai rumah tinggal juga digunakan sebagai tempat acara-acara yang bersifat adat, ritual, dan sebagainya (Wahyudi, 2018). Tujuan tersebut menyebabkan ruang keluarga dibuat begitu besar agar memenuhi banyaknya anggota keluarga, walaupun pada perjalanan waktu terdapat beberapa perubahan seperti penempatan jendela akibat berkurangnya konflik antar Suku yang terjadi.…”
