Analysis Of Variation Of Paddle Wheel Photovoltaic Wheel Form In Microalgae Cultivation On Electricity Consumption
No full textThe main problem that is often found in the failure of microalgae production is poor water quality during the maintenance period. One of the causes of deteriorating water quality is the lack of oxygen which endangers microalgae which can inhibit cell growth so that it can reduce its productivity. On this basis, efforts are needed to refresh the water or aeration to help increase the dissolved oxygen (DO) level in the microalgae growth container using a paddle wheel. The development of an aerator blade design that has optimum efficiency is needed to reduce high electricity consumption and see more effective cell growth. For these problems, in this study, variations of the paddle wheel will be analyzed. Variations in the shape of the wheel used, namely straight and curved with the available aerators, are expected to have an optimum speed, area coverage and increase the amount of dissolved oxygen (DO). The method used is the experimental method . Based on this research, it was found that an increase in the value of cell growth occurred in variations in the shape of a straight paddle wheel of 122 cells/ml

Economic Behavior Changes On Organic Food Consumption In Pandalungan Community
No full textThe districts of Situbondo, Bondowoso and Jember are the centers of residence for the Pandalungan community. Pandalungan community is a society with mixed cultures, namely Java and Madura. Most of them live in urban areas. Like other community entities, some of these communities have not consumed organic food plants, given the scarcity of information about organic plants. The objectives of this study were: (1) to determine the effect of plant organic food product attributes as healthier food plants, and the discomfort caused by organic food plants on the motivation to shift consumption through the attitude of shifting non-organic food plant products to organic food plants. ; (2) to determine the effect of moderating motivation to elaborate information on the effect of product attributes and discomfort on product switching attitudes. The analytical method used is Structural Equation Modeling (SEM) with AMOS applications, the research sample of 250 respondents selected from the three research areas, with proportional random sampling method. The results of the study show that product attributes have a positive and significant effect on product switching attitudes, as well as their influence on the motivation to shift consumption to organic food crops. Meanwhile, discomfort has a significant negative effect both on product switching attitudes and on motivation for shifting consumption. Product switching attitude has a positive and significant effect on the motivation to shift in consumption. The moderating effect of motivation on elaborating information strengthens the effect of product attributes on product switching attitudes, but the moderating effect of motivation on elaborating on information through discomfort is proven insignificant. The interactive structural equation function mathematically can be written as follows: (1) SK = 1,420 AT– 0.773 KN + 0.278 ATml - 0.198 KNml + e3; and (2) NI = 1.366 AT - 1.466 KN + 0.768 SK + 0.425 ATml - 0.787 KNml + 0.570 SKml + e4. shows that product attribute improvements can be widely and continuously informed to the public so that people will know and be able to make comparisons with competitors' products. This will motivate more wisely towards product switching. This finding related to the limited alternative product choices; product constraints are difficult to find, high prices (Zanoli & Naspetti; 2002, and Chinnici, and friends; 2002). Low availability in the market (Kalafatis, and friends;, 2009: Magnusson, and friends; 2012, Vindigni, and friends; 2002, Tarlanen & Sundqvist; 2005, Chen; 2009); and the minimum number of alternative options (Chinnici, and friends; 2002) as well as the cost of switching (Anton, and friends; 2007)
