At present, artificial bait casting and water quality detection are widely used in the domestic aquaculture, it is difficult to improve the yield and quality of the output of aquatic products such as fish, prawn and crab because of low production efficiency and limited labor force. This paper proposed an automatic aquaculture workboat driven by air propellers based on 3G(GNSS、GIS、GPRS), equipped with main controller ARM11, automatic path planning and tracking based on GIS and GNSS system and remote monitoring with GPRS communication module, the workboat can perform bait casting and water quality parameters detection such as dissolved oxygen, pH, water temperature, ammonia nitrogen and salinity automatically according to the aquaculture tasks. It can improve the aquaculture work efficiency and save the manpower and the material resources.

The Impact

This study examines the impact of two-breed (PXW) and three- breed (PxWxIDF) system of sheep crossing on the results in terms of yield and quality of meat of lambs, weaned at 60 days of age and fattened up to 120 days of age. Study was carried out on the experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and the following breeds of sheep were used for crossing: Pirot pramenka (P) W?rttemberg (W) and Ile de France (IDF). As maternal basis the Pirot Pramenka and two breed crosses were used, and as improvement breed - Ile de France rams. Pre-slaughter body mass of two-breed and three-breed crosses was: 32.63 and 34.48 kg. Values of dressing percentage warm carcass with head and offal were: 59.0 and 58.4%. The share of the category I meat on analogue treatments was: 37.07: 37.48%, meat of category II: 33.98: 32.41%, and the meat of category III - 28.69: 26.87%. Meat to bone ratio was: 2.3:1 in two- breed crosses, whereas in the three-breed crosses it was 2.7:1. MLD surface was 11:49 and 11:45 cm2. Regarding the chemical and technological characteristics, there were no significant differences among the treatments (P> 0.05).

In order to save fertilizers and improve the utilization rate of fertilizers, the effect of nano-carbon materials and fertilizers on the quality and growth of crops was studied, and the significance of nano-carbon to promote nutrient absorption was expounded. In this review, the mechanism of the influence of nano-carbon materials on plants is summarized. Nano-carbon fertilizers can significantly improve the yield and quality of crops, and have a significant impact on the utilization rate of fertilizer. The existing research shows that nano-carbon synergist fertilizers, nano-carbon biocompound fertilizers and nano-carbon bio-bacterial fertilizers have been applied in crop planting and have a good effect of increasing crop yield.

The main purpose of this research was to observer effect co-solvent type (n-Hexane, chloroform and without co-solvent)  toward yield and quality of biodiesel via in situ transesterification process using microwave irradiation. The process was studied at microwave power 450 watt, reaction time 4 minutes, methanol to seed ratio 25:1 and catalyst concentration 5%. The physicochemical parameters of the biodiesel produced such as viscosity, density and acid value were analysed and compared with the SNI 7182-2012 standard. The experimental result showed the maximum yield biodiesel 78,32% obtained by using co-solvent chloroform.Test result of physicochemical properties (viscosity, density and acid value) of biodiesel products using co solvent n-Hexane, chloroform and without co solvent showed that these products conform to the SNI 7182-2012 standars. The type of co-solvent only affectedon biodiesel yield dan not affected on biodiesel quality (viscosity, density and acid value).  ABSTRAKTujuan penelitian ini adalah untuk mempelajari pengaruh jenis co-solvent (n-Hexane, chloroform dan tanpa co-solvent) terhadap rendemen dan mutu biodiesel secara trasesterifikasi in situ menggunakan radiasi gelombang mikro.
