Kampung Empat Balai is one of the old villages in Kuok District, Kampar Regency. The kampung comprises traditional Malay houses as cultural heritages that urge to preserve. The house has a unique roof shape and carvings pattern. However, the house is endangering due to a lack of maintenance. This research has aimed to identify the construction of houses that belong to the Bawi ethnic group people. A qualitative descriptive approach has been carried out to investigate and analyse this Malay house. This research found that the Bawi's house has a curving roof type which is known as part of the Lotiok roof type. This stilt house has a structural system in the form of a series of line elements with non-rigid joints that bind each other using notches and pegs as a connection system that is anticipated for earthquakes. Materially, this Bawi'House uses wooden-based materials throughout its construction systems, such as floors, walls, columns, girder beams and roof trusses.Malay house; traditional construction; lontiok roof; wooden-based materials

The old town area gives a significant character on urban heritage, in particular regarding Kota Pusaka programme in Indonesia. While enhancing the character, in this case, part of Siak Sri Indrapura City has burned out, and raise serious issues to the local government due to lack of written data on how to reconstruct the area. In this case, extracting field data by conventional measurement from remaining buildings found ineffective. Not only consume time, but these methods have also created social and psychological problems for local people. Therefore various indirect field methods such as desktop research, digitising, and documentation are needed to be completed by more fast and interactive direct field methods. This paper confirms that field data which compiled by various field methods can more contribute to reconstructing the character of the old town.

Masjid adalah rumah tempat ibadah umat Muslim. Masjid artinya tempat sujud, juga disebut musholla atau langgar. Selain tempat ibadah masjid juga merupakan pusat kehidupan komunitas muslim. Masjid Nabawi merupakan masjid permanen pertama yang didirikan oleh Rasulullah yang berfungsi mewadahi kegiatan peribadatan Islam dan penerapan ajaran agama Islam. Masjid Nabawi kemudian menjadi model bagi pembangunan masjid-masjid berikutnya di seluruh dunia. Masjid Syifaunnas sudah berdiri cukup lama sehingga perlu adanya pembaharuan fasad masjid sesuai keinginan masyarakat setempat untuk mendukung sarana dan prasarana kegiatan keagamaan yang sedang bergerak cukup cepat seperti pendidikan dan kegiatan massal. Pengurus bekerja sama dalam kegiatan   pengabdian untuk mewujudkan dokumen perancangan kawasan masjid Syifaunnas. Kegiatan ini menggunakan deskriptif kualitatif dengan melakukan pengumpulan data melalui observasi dan wawancara. Pendekatan kegiatan adalah bottom-up approach yaitu dengan penulusuran minat dan keinginan pengguna.  Hasil kegiatan ini adalah mendapatkan dokumen perancangan kawasan masjid Syifaunnas dengan menerapkan konsep fasad arsitektur masjid Nabawi. Dalam rancangan pembagian berdasarkan zonasi yaitu zona transisi, zona masjid, dan zona penunjang.  Dokumen ini bermanfaat bagi panitia pengembangan masjid Syifaunnas sebagai panduan dalam pelaksanaan pembangunan masjid.

The objectives of this article are to seek the opportunity to enhance the local Indonesia timber material physical performances (encompassing the low-class quality of III and IV timbers with the Modulus of Elasticity (MOE) = 5,000 - 9,000 MPa) utilizing laminated composite technology to become higher-class timber quality (class II) with the Modulus of Elasticity (MOE)> 15,000 MPa so that it can be used as an alternative material for constructing the bridge mainframe structures (girder beams) especially for the Indragiri Hilir regency, Riau Province, Indonesia. This regency needs several hundred small-medium bridges for connecting 20 districts, 39 wards, and 197 villages using local materials such as local timbers. This laminating technology is not a new technology but the utilization of this technology for constructing the main bridges structures is challenging and limited to the implementation in the civil construction industrial sector. This study composed 2 types of the low-class quality (lcq) of timber materials (such as Shorea sp and Shorea peltata Sym) and 2 types of medium class-quality (mcq) ones (Dipterocarpus and Calophyllum) for constructing the main bridge structures. Based on the laboratory test results utilizing 80% of lcq materials and 20% mcq ones, these composite timber materials may increase the timbers MOE by 145% to 166% from the existing MOE value of the mcq solid timbers. Based on the simulations these laminated composites wooden bridge girders 2 x (70x20) m2, these timber materials have passed all the tests and the application of this technology may improve the lcq timber values and it could be used for an alternative material of the bridge girder's main structures.

Title: Typology of Malay Vernacular Architecture Uma Kabuong Limo in Pulau Belimbing Village, Kampar District   One form of residential culture can be seen in the architecture as a residence for the people of Belimbing Island Village, Kampar regency. The house as a residential function always develops according to the needs and image of the owner, so changes in the Uma Kabuong Limo building are found. Uma Kabuong Limo can be categorized as vernacular architecture because Uma Kabuong Limo is a product and name that has existed for several generations with a development process that adapts the socio-cultural and cultural of the Malay community. The nature of this simplicity is not only a residential building but also becomes the identity of the community. Through the study of the architectural typology of Uma Kabuong Limo was studied through the approach of the computational model of heritage building information modeling (HBIM). This modeling is expected to get an in-depth and precise analysis to describe the typology process more accurately. This assessment process begins with field data observation, modeling, and discussion of building typologies. The Uma Kabuong Limo buildings observed are six buildings representing the distribution of facilities in The Belimbing Island Village. The findings were the existence of a slightly different basic shape equation in the kitchen. One of the buildings changed the shape of the roof, called the paranginan roof, a multi-storey roof. The more engravings and tidiness of home making depict, the higher the level of the social status of the building owner.
