It is related with amino acid tryptophan as a precursor for building IAA. However some bacteria such as Bacillus sp. and Escherichia coli enable to produce IAA without L-tryptophan on culture medium via the tryptophan independent pathways. This study aims to determine the potential of indigenous Bacillus sp. and E. coli isolate in producing IAA via Trp-independent pathways (without L- tryptophan). The stage of this study consists of growing of isolate on liquid media without tryptophan and measuring the levels of IAA using Salkowsky method. Bacillus sp and Escherichia coli could produce IAA with the concentration of 0,0236 mmol/L and 0,024 mmol/L, respectively. The concentration of IAA produced by these bacteria is quite low because of their ability to synthesis IAA from the independent tryptophan pathway. The independent tryptophan pathway means these bacteria could synthesize IAA without using tryptophan as a precursor on their growth medium.\u0000n","PeriodicalId":231292,"journal":{"name":"Journal on Satisfiability, Boolean Modeling and Computation","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127112257","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}

Badan Pusat Statistik (2015) reported that there are merely two orthopaedic surgeons in Lampung province having to serve about 8.117.268 people. Meanwhile, based on Ministry of Health of Republic of Indonesia, the ideal ratio between doctor and people is 12.2 doctor for each 100.000 people. Besides that, sometimes the surgeons need to serve more than one medical facility. Consequently, the patients might feel unpleasant. The lack of human resources becomes the main reason for developing expert system for diagnosing orthopaedic diseases.  The expert system is able to diagnose orthopaedic diseases as well as fracture, dislocation, osteoarthritis and osteoporosis. The system is developed by using forward chaining methodology. This methodology is suitable for identifying a disease based on their symptoms. The result shows that the expert can answer 45 % of questions by identifying 6 main symptoms without continuing to following symptom questions.","PeriodicalId":231292,"journal":{"name":"Journal on Satisfiability, Boolean Modeling and Computation","volume":"5 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113941615","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}

Daerah Lampung memiliki potensi energi surya rata-rata 4,43 kWh/m2/hari dengan variasi bulanan sekitar 7 persen. Lampung juga dinyatakan cocok untuk aplikasi teknologi energi surya fotovoltaik karena memiliki karakteristik komponen radiasi langsung yang lebih dominan daripada komponen radiasi baurnya. Institut Teknologi Sumatra (ITERA) dalam perkembangannya sangat membutuhkan peningkatan pasokan energi listrik setiap tahunnya. Sehingga perlu lirikan akan energi lain sebagai dukungan dalam mewujudkann forest kampus dan pemenuhan energi. Untuk mengetahui potensi energy surya di lingkungan ITERA, maka dilakukanlah study awal energy surya yang dapat diproduksi. Tujuannya adalah agar didapat informasi potensi yang real untuk perkiraan pengembangan energy surya di lingkungan Institut. Pengukuran potensi ini menggunakan rangkaian panel surya yang disambung ke beban Resistor dan lampu yang diatur maksimum.
