Bugis ethnic in South Sulawesi Province, Indonesia is known as an old tribe who domiciled in the south peninsula of Sulawesi island. They have characteristics of high legacy, culture by the script called lontaraq and life in a traditional stilt house called bola ogi. This house was built in certain methods and become a research problem. The goal of this study is to reveal the construction method and the performance of the Bugis traditional house in facing of wind disaster. The research methods are field observation and in-depth interview. Field observation to reveal the old construction methods of 100 years traditional the Bugis house and its performance in collapse by wind disasters. In-depth interview to strengthen information. The research revealed that Bugis house made of wood and its built-in certain construction methods called mappasituppu. Structure system consists of the main and secondary structure which is joined together rigidly an appropriate hierarchy. The part of the structural member is setting follows natural way. The wind attack saw that building structure collapse step by step depend on its function in the structure as a whole. The lesson from Bugis in construction method is the part of the structure system best to design in the proper strength hierarchy. The strength, structure hierarchy is the maximum strength part of structure equal to the minimum strength of the structure which supports them.
Maradeka life is the highest idea of Bugis ethnic in South Sulawesi Province. Life and maradeka terminology are a unity which is found by exploring Bugis script called lontaraq.The research topic is learning from Bugis in planning and design space. The main objective of this study was to reveal the basic consideration of Bugis ethnic in space design which is applied in they traditional house. The research method is historical interpretation and logical argumentaion. Historical interpretation to reveal the meaning of maradeka in script. Logical argumentation to reveal local knowledge in space problem solving for human better life. The script which used to explain maradeka derived from lontaraq Meong Mpalo and lontaraq Attoriolonge Ri Wajo. The study results that Bugis house space design for maradeka life. The application of maradeka life is suitable to vertical space arrangement in Bugis house. The highest space in Bugis house function as food stuff storage as life warranty. The lowest space function as the support of daily life. The human space placed in the middle of life warranty and support of daily life. This space composition suitable to used as basic consideration in macro planning too. Good planning should be prepared space for food stuff, space for living, and space for supporting life. This spaces should be interconnected and proportional to regard for humanity.
This study aims to reveal the lifting power of the bamboo raft in holding the weight of the house on stilts so that it stays floating on the water. This research was conducted on the shores of Lake Tempe, precisely in Laelo Village, Tempe District, Wajo Regency. The method used in this research is a field study to determine the real situation in the field so that the real condition of the floating house is known. Furthermore, calculating the load used on the floating house based on the results of field studies. The final stage of the research is to test the raft lifting capacity of the floating house. The data will be analyzed according to Archimedes' Law, so that it can be seen that the bamboo raft can stay afloat even though it is given an Architectural building as heavy as a simple stilt house. The results of this study revealed that the average number of bamboos used as a raft was 175 stalks, and the mean diameter of bamboos was 7.67 cm or 0.077 m. It is known that the volume of the rod segment cavity is 0.103 m³, so the total volume between sections on the floating raft on Lake Tempe is 18.058 m³. The lifting capacity of bamboo rafts is directly proportional to the volume of bamboo joints used as rafts. The experimental test results obtained revealed that the lifting capacity of bamboo per m3 was 874.51 kg, so the lifting capacity of the bamboo raft in Tempe Lake was 18.058 m³ x 874.51 kg / m³ = 15,789.13 kg. While the results of the calculation of the burden of a simple house are known by calculating the house's own load and the living load experienced by the house, and the weight of the house is 9,314.121 kg. With the ability to lift a bamboo raft of 15,789.13 kg, the difference between the lifting capacity of the bamboo raft and the weight of the floating house is 6,475.01 kg. The ideal number of bamboo culms is 129 with a safety factor of 25%. There is an efficient use of 46 bamboo sticks.
Abstrak Metode pelengkungan kayu solid merupakan salah satu metode pelengkungan kayu yang saat ini masih terus dikembangkan untuk mendapatkan metode pelengkungan kayu yang lebih efisien. Namun, metode ini memerlukan peralatan dan teknik yang khusus. Pemilihan benda uji dari jenis kayu yang banyak digunakan untuk pembuatan furniture dan bahan konstruksi di kota Makassar, salah satunya adalah kayu jati putih. Penelitian ini ingin menemukan hubungan dimensi dan karakter lengkungan kayu yang ideal tanpa perlakuan awal, maka rumusan masalahnya adalah berapa jarak radius lengkung kayu jati putih dengan ketebalan 0,5 cm, 0,7 cm dan 1 cm yang dapat dipakai sebagai ornamen arsitektur bentuk bebas. Lalu, adakah hubungan radius lengkung kayu jati putih dengan ketebalan kayu, lebar kayu dan waktu saat kayu dilengkungkan. Tujuan penelitian adalah menganalisis radius lengkung kayu jati putih dengan ketebalan 0,5 cm, 0,7 cm dan 1 cm yang dapat dipakai sebagai ornamen arsitektur bentuk bebas dan mengungkapkan hubungan radius lengkung kayu jati putih dengan ketebalan kayu, lebar kayu dan waktu saat kayu dilengkungkan. Penelitian ini menggunakan metode eksperimental untuk menganalisis datanya dan metode skala 1 : 1 atau Performance Based untuk metode pengujian sampelnya. Hasil penelitiannya adalah nilai radius terbesar dari tebal 0,5 cm adalah 35,47 cm, tebal 0,7 cm adalah 65,42 cm dan tebal 1 cm adalah 91,73 cm. Untuk waktu lengkung yang dapat bertahan lebih lama juga dengan ketebalan 0,5 cm yaitu selama 1 hari. Maka hubungan radius lengkung dengan ketebalan kayu jati putih sangat erat, dimana semakin tebal kayu maka semakin besar radius lengkung kayu jati putih.
