“…In this paper applied the drip irrigation method, which is the most promising method for use combined with conditions in water shortage and for that reason applicable to a wide range of soils and crops [6][7][8]. Furthermore, presents its ability application in many provisions with a range of benefits to water saving and combined with many automation [9][10][11][12][13]. The rapidly increase of energy demand has become one of the major issues to the modern world and presently, most of the covered by fossil fuels [14].…”

This paper regards research for evaluation of the effect of the surface and subsurface drip irrigation method in the production of biodiesel from sunflower crop and in the saving of irrigation water, and in economic performance which directly concerns the Greek producers. The research was conducted in the Central Greece, in a field in the Farm of the University of Thessaly. The following treatments were organized: a) the surface (AUTO (E)) and b) the subsurface (AUTO(Y)) drip irrigation method, in which the irrigation was scheduled by an automatic evaporation pan. The research concerns the growing seasons of the years 2011 and 2012.

“…The cloud point is the temperature at which a cloud of wax crystals first appears in the oil when it is cooled. A high cloud point limits the application of biodiesel operating at lower temperatures than diesel (Ramkumar & Kirubakaran, ). The pour point is the temperature at which the fuel becomes completely solidified.…”

“…The pour point is the minimum temperature at which a vehicle can be operated without a heating aid for the fuel. The pour point of biodiesel is higher than that for diesel, so it makes it less feasible to operate a vehicle with biodiesel in a colder region than with diesel (Ramkumar & Kirubakaran, ). Sanjid, Masjuki, Kalam, Abedin, and Rahman () found a cloud point of 5°C and a pour point of −18°C for biodiesel produced from waste mustard oil.…”

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.

Scylla serata shell was decomposed at various temperatures ranging from 700-1100 o C to obtain calcium oxide. Calcium oxide from decomposed Scylla serrata shell was characterized through X-Ray analysis, FTIR spectroscopy, and morphology analysis. Furthermore, decomposed Scylla serrata shell was used as catalyst for transesterification of tropical edible oils to form biodiesel. Biodiesel was characterized through density, viscosity, fatty acid value, and iodine number. The results showed that decomposed Scylla serrata shell at 900 o C could produce calcium oxide similar with standard, which was indicated from X-ray powder diffraction pattern of decomposed shell with JCPDS data. FTIR spectrum showed that main vibration of calcium oxide was observed at 393 cm -1 . Morphology analysis using SEM indicated that uniform calcium oxide was obtained after decomposition. The use of decomposed shell as base catalyst for transesterification of tropical edible oils resulted biodiesel with density, viscosity, fatty acid value, and iodine number appropriated with SNI standard. Keywords: transesterification, edible oils, biodiesel, Scylla serrataAbstrak (Indonesian): Scyalla serrata telah didekomposisi pada berbagai suhu dari 700-1100 o C untuk diperoleh kalsium oksida. Kalsium oksida hasil dekomposisi dari cangkang Scylla serrata dikarakterisasi melalui pengukuran sinar X, analisis FTIR, dan analisis morfologi. Lebih lanjut, dekomposisi cangkang Scylla serrata digunakan sebagai katalis transesterifikasi minyak yang dimakan dari daerah tropis menjadi biodisel. Biodiesel dikarakterisasi melalui penentuan densitas, viskositas, nilai asam lemak, dan bilangan iod. Hasil penelitian menunjukkan bahwa dekomposisi cangkang Scylla serrata pada 900 o C dapat menghasilkan kalsium oksida mirip kalsium oksida standar yang diindikasikan dari pola difraksi XRD yang mirip data JCPDS. Spektrum FTIR menunjukkan vibrasi utama kalsium oksida teramati pada bilangan gelombang 393 cm -1 . Analisis morfologi menggunakan SEM menunjukkan bahwa bentuk yang lebih seragam diperoleh setelah proses dekomposisi. Penggunaan cangkang hasil dekomposisi sebagai katalis basa untuk transesterifikasi minyak yang dimakan dari daerah tropis menghasilkan biodisel dengan densitas, viskositas, nilai asam lemak, dan bilangan iod yang sesuai dengan standar SNI.
