Abstrak: The main compounds of citronella oil are citronellal, citronellol, and geraniol, all of which determine the fragrance intensity and price of the citronella oil it self. Separation of those compounds increased the value of citronella oil. The aim of this research is to obtain the optimum amounts of citronellal, citronellol, and geraniol fractions by vacuum of fractional distillation technology. Conditioning process using 30:1 reflux ratio obtioned purer citronellal, citronellol, and geraniol than conditioning process with 10:1 reflux ratio. The separation process was held in 5 - 4 mBar vacuum pressure and the variation of reflux ratio 10:10, 20:10, 30:10. The optimum amounts of citronellal, citronellol, and geraniol was obtioned in the variation of reflux ratio 10:10, they are 90.670 % of 620 ml, 41.101 % of 160 ml, and 53.581 % of 500 ml respectively

Abstrak: The aim of this research is to determine the suitable condition of Short Path Distillation (SPD) which can increase the purity of citronellol and geraniol rich fraction by separating the citronellal component and to know the potential yield of SPD. The input material for the process was the citronellol and geraniol rich fraction of Java citronella oil obtained by vacuum distillation. The equipment used was Short Path Distillation KDL 1 unit type falling film evaporator. Distillation process conducted by stepwise increasing of distillation temperature. Operation condition of SPD is managed by fix condition including range of distillation temperature from 58ºC to 62ºC, pressure 10-3 mbar, condenser temperature 10ºC, flow rate 1-2 drop per second, rotor speed 200 rpm. Process parameter was distillation temperature increase of 1ºC and 2ºC in every run as treatment. Citronellal, citronellol, and geraniol content was analyzed using Gas Cromatography and evaluated according to physicochemical properties such as : density, refractive index, and color. The experiments result in an increase of purity level of citronellol and geraniol rich fraction from 41,44% to 60%. The process yield was 54.97%, achieved by stepwise increasing of distillation temperature of 2ºC. It physicochemical properties as follow : density 0.890, refractive index 1.469, and amber wich is according to SNI-06-3953. Meanwhile, by product was obtained has citronellal content 25,87% and it yield was 35.11%.

Abstrak: Increased use of Information and Communication Technology (ICT) in an organization aims to enhance competitiveness in various fields. In this era of globalization education becomes one of the fields that make use of ICT as a medium to enhance the educational process at a primary, secondary and higher. Enterprise architecture is a way to build the information architecture of an organization that focuses on the architecture of data, applications and technology. The methodology use to compile the information is TOGAF architecture framework. TOGAF provides a method and tools to build, manage and implement enterprise architecture and maintenance. Key elements of TOGAF are the Architecture Development Method (ADM) that provides specific features for enterprise architecture development process. ADM is an important feature that enables enterprises to define business needs and build a specific architecture to meet those needs. ADM consists of stages required in building the enterprise architecture, the stages of ADM is a Preliminary Framework and Principle, Architecture Vision, Business Architecture, Information System Architecture, Technology Architecture, Opportunities and Solutions, Migration Planning, Implementation Governance and Change Management Architecture. The results of this research is the business architecture, information system architecture consisting of data and application architecture, technology architecture, as stipulated in the ICT blueprint. The architecture consists of business consists of the main functions of which include the New Acceptance of Students (PPDB), Teaching and Learning (PBM), and the Release of Academic (SPA), while the support functions include Administrative Management (MTU), Infrastructure Management (MSP), the Center Computers and Language (PKB), and Financial Management (MK) are modeled using Michael Porter's Value Chain. Data architecture consists of 46 data entities of the seven business functions; application architecture consists of 21 applications.
