Abstract

Enterprises producers of ornamental plants mostly in the form of UKM that has not been touched by the thought of utilizing advertising as a means of promotion merchandise. A phenomenon that perceives that the cost of advertising spending for the promotion, will bring revenue burden for entrepreneurs producers of ornamental plants. Therefore, the author tries to see how the level of income of a company producer of the promotional expenses. Data obtained books adapted by Carter Hill, William Griffiths, George Judge, in the book Undergraduate Econometrics, John Willey & Sons Inc., New York, 1988. The data are taken as many as 15 pieces with variable between the levels of income/revenue expenditure promotional costs. That is the level of income is influenced by promotional expenses. Thus the dependent variable (Y) is the income and promotion expenses (X). This paper will attempt to provide an analysis of the level of revenue company producers of ornamental plants against promotion expenses as part of the system sales of its products. The assumption is estimated that revenue will increase when enlarged promotional expenses. The purpose of the description in this paper is to discuss the hypothesis of economic phenomena, especially on the behavior and function of the company's revenue with the cost of sale (in this case the cost of advertising). The methodology used is through the approach of econometrics at the company's plant landscaping and regression analysis (linear) with SPSS method. From the discussion, we concluded among other things, income / revenue are highly dependent on spending promotional / advertising. Therefore if the company will still generate the maximum benefit it is necessary expenses advertising costs.

Abstract

Vehicle population in Indonesia which are fueled by oil increase annually while the petroleum reserves are more limited. Parallel with the increasing oil fuel consumption for the vehicles causing the increasing fuel subsidies and air pollution as well. To reduce the subsidy for oil fuel and the air pollution it is necessary to find out the alternative fuel which is environmentally friendly as a vehicle fuel and are available in huge amount. One of the alternative fuels which is environmentally friendly is the gas fuel. The problems for developing the use of gas fuel are that the availibility of the filling stations are still limited and the users feel unsafe to use the gas fuel. The research results showed at dynamometer (dynotest) that the gas fuel can be used as a alternative fuel for oil but unfortunately the vehicle designed has a declined torque at variable rotation (rpm) and a decrease Pouzer to variable rotation and exhaust emission is very environmental friendly (good) especially causes by decreasing emissions of CO, CO2, HC and O2 and increasing Lamda.

Abstract

Sequencing techniques Deoxyribonucleic Acid (DNA) at this time is a method to identify the genetic basis of living beings, including to determine the accurate genetic relationship of several DNA sequence data. Kinship clearly and easily can be expressed in the form of a phylogenetic tree diagram (Phylogenetic Tree). This diagram represents kinship obtained from the elektroferogram process of electrophoresis sequencing of DNA bases. From some sequences experimental results using sequence analysis application program gradually, starting from installing, editing, and alignment so as to obtain the analysis and phylogenetic branching diagram view. This study uses a sequence analysis program Mega-7 (Molecular Evolutionary Genetics Analysis) to obtain a phylogenetic diagram for high accuracy and relatively easy to operate. This program can translate image data into nucleotide bases that shows the kinship of the distance the nearest branch with a standard sequence. The major advantage of this program is that it can do some analysis in a single program.
