Abstract

Dalam masyarakat tradisional, segala sesuatu yang menyangkutkehidupan masyarakat selalu di lakukan bersendikan adat istiadat. Adatistiadat menjadi semacam pedoman dalam berpikir dan bertindak sesuaipola kehidupan masyarakatnya. Arsitektur Tradisional sebagai produkbudaya yang diwujudkan dalam bentuk fisik bangunan melalui prosesperenungan yang mengaitkan atau menghubungkan antara kehidupan seharihari dan kepercayaan terhadap alam semesta. Terwujud baik dalam tingkahlaku secara berinteraksi, termasuk perlakuan dalam tata cara membangunrumah di dalam lingkungan alam sekitarnya. Tata cara pembuatan rumahmenurut konsep arsitektur tardisional Bugis Bone, merujuk pada pesan atauwasiat yang bersumber dari kepercayaan dan adat istiadat yang dianut olehmasyarakat Bugis Bone, mulai pemilihan tempat, penentuan arah peletakanrumah bentuk arsitektur, hingga penyelenggaraan upacara ritual ketikaproses membangunnya. Dalam proses pembangunan ini merupakanrangkaian dialog dan keputusan antara penghuni rumah dan panrita bola.Rumah Bugis merupakan refleksi dari penghuni dan masyarakatnya.Bangunan rumah tersebut dibuat tidak hanya memberi fungsi tetapi jugamemberi nilai estetik yang pada dasarnya merupakan bentuk prilakuspiritual para pemiliknya. Hal tersebut terlihat pada bagaimana merekamembuat rumah sesuai dengan pandangan kosmologis mereka. RumahBugis dibangun memiliki makna simbolis yang sangat kuat, di manakonstruksi rumah dibangun dalam tiga ruang yang mewakili tiga makna.Makna yang diwakili tersebut merupakan cerminan akan tiga dunia yangdiyakini masyarakat Bugis, yaitu dunia atas, dunia tengah dan dunia bawah.Sedangkan secara fungsional, rumah Bugis memiliki fungsi yangmenjelaskan bagaimana kehidupan itu harus dibangun dan sosialitasmereka terhadap keluarga, masyarakat dan lingkungan mereka.

Abstract

Coal in future will become a prospective candidate for alternative energy source. However, South Sulawesi coal still contains high concentration of sulphur which becoming a disadvantage for being used as an alternative energy. So far we need to develop such desulphurisation methods that not only practice abd efficient but also environmental friendly.The use of vegetable oil, which in oxidized form produces hydroperoxide, a powerful oxidizing agents, in desulphurisation process can oxidized the organic and inorganic sulphur of coal.The goal of this research will be, (1) to find out the NaOH optimum time and concentration for the initial treatment to effeciently desulfurized the coal, (2) to process, (3) to discover the maximum ratio of coal-oil in which can gave the maximum loss of sulphur (4) to justify maximum calories values of coal after the coal being desulfurized with vegetables oils.The research was carried out first with crushing the coal into about 200-mesh size following by analyzing the sulphur contents, which gave a result of 2,86% before desulphurized.In the initial treatment for desulphurisation, 75 mL of NaOH 1% and 5% was added to the coal for 1,3,5, and 7 hours respectively. After that coal was dried in temperature of 100oC. The maximum result from of this treatment was found 5% NaOH for 5  hour treatment, which reducing the content of sulphur about 2,239% or can desulphurized the coal until 22,035%Furthermore, variation of coal-vegetables oil ratio from (2:1), (1:1), (1:2), (1:3) and to the ratio with the constant absorbance values justified that the maximum ratio of (1:1) gave the maximum percentage of sulphur loss about 74,24% for traditional oils and 66,61% for crude palm oil respectively. These treatment also increasing the coal calories values 6176,80 to 6449,74 – 7767,09 kilocalories.Based on these result it can be concluded that the vegetable oil can effectively used in coal desulphurisation.
