This study aims to determine the content of bioactive compounds contained in the petiole by Gas Chromatography Mass Spectrophotometer (GCMS) method. Preparation of ethanol extract of petiole using maceration method with 96% ethanol solvent. The study used gas chromatographic tools and mass spectra which were evaluated using MASSLAB program. The data obtained from the GCMS machine is then analyzed using the NCBI database pubchem software (https://pubchem.ncbi.nlm.nih.gov/). The results of this study indicate that the content of bioactive compounds on the petioles of buasbuas more than 50 libraries contains about 150 species of compounds with a range of RT and% area respectively 4.684 to 28.155 and 0.16 to 15.56%. The content of bioactive compounds shown this data indicates that very large potential of buasbuas plants to be explored and exploitation as a nutritious plant. The results of this study can be used as the foundation in the development program of the potential utilization of bioassemblance of buasbuas plants. In further research it is necessary to analyze the other parts of the plant and make comparisons to complete the available databases.","PeriodicalId":11527,"journal":{"name":"Elkawnie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85817668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Harga bahan bakar murah, jika harga bahan baku yang digunakan untuk membuatnya murah dan banyak tersedia di pasaran, dan cara atau teknologi yang digunakan untuk mengolahnya sederhana. Secara ekonomis, menggunakan briket akan lebih hemat dibandingkan menggunakan bahan bakar lain.

Hal ini dipengaruhi oleh perkembangan ilmu pengetahuan yang diiringi dengan perkembangan teknologi digital yang begitu pesat selama beberapa dekade terakhir. Dunia perancangan arsitektur baik itu di bidang profesional maupun di bidang pendidikan arsitektur tidak luput dari pengaruh teknologi digital. Teknologi digital telah menggeser metode tradisional dalam dunia desain arsitektur walaupun pada faktanya masih ada beberapa arsitek atau desainer yang menggunakan metode tradisional. Hal ini disebabkan dengan menggunakan teknologi digital proses perancangan arsitektur menjadi lebih efisien dan mudah. Disamping itu dengan menggunakan teknologi digital dalam proses desain arsitektur juga memungkinkan arsitek atau desainer untuk bereksplorasi terhadap bentuk-bentuk geometri yang tingkat kompleksitasnya lebih tinggi. Hal ini dimungkinkan karena dengan perkembangan teknologi digital yang begitu pesat, komputer tidak hanya digunakan sebagai media untuk menghasilkan produk gambar atau mempercepat proses desain saja (komputerisasi) , akan tetapi komputer sudah berperan aktif dan dijadikan bagian dalam proses perancangan arsitektur (komputasi).
