Some of triboluminescence materials have the property of shortwave light emission, which is possible to make them being used as the light resource of pest-insects phototaxis trapping. The inorganic composite phosphors Sr2MgSi2O7:Ce and organic composite phosphor Mn-PMBB are tested to have the violet-blue spectrum and green spectrum glowing respectively; Their vertical axis wind driving triboluminescence unit is designed and fabricated on the basis of squirrel cage structure friction pair with multi-glass bars against on the cylindrical phosphor. The persistant wind driving tribo-luminescence is obtained in the experiment of wind driving triboluminescence unit. Further the triboplasma of N2 and N2- Ar gases closed in the quartz tube is researched by means of PTFE elctret on quartz tube friction pair, and a high intensity triboplasma light emission with more than 50000 counts is obtained in the span of 310-420nm spectrum that supplies a more suitable shortwave spectrum of phototaxis trapping pest insects. The annular quartz glass tube is designed to constitute PTFE against on quartz friction pair; The triboplasma emission device is fabricated utilizing three stacking layer structure of PTFE-anuular quartz tube friction pairs, and the S-type vertical shaft wind tuebine is used to form the wind driving triboplasma emission unit. The violet-blue emission spectrum of N2-Ar gas troboplasma is obtained in the test of vertical wind driving triboplasma unit.

Consumption of fish in Indonesia continuously increase from 2000 to 2014. Particularly fish farming in Java from 2006-2014 is quite high, so there need to be adequate facilities for fish farming. Responding to these challenges, we developed Offshore Cage Ocean FARMITS technology specifically designed For the southern waters of Java Island. This paper discusses the static structure strength analysis of deformation and maximum yield strength that occurs on the offshore cage structure of Ocean FARMITS. The frame structure made of hollow pipe made from HDPE will be placed at 4,41m Wave Height, with a period of 19s. Numerical simulations are performed to obtain a motion response RAO and structural response due to random waves. This Structure is then analyzed under mooring conditions with the Catenary Mooring configuration. Rope stress that occur due to environmental loads will give tension stress to the structure, resulting in the offshore cage structure to occur maximum stress and deformation. The result of this research is to prove that the structure that is made by HDPE able to restrain the tension force of mooring line stress. This has been validated by the standard of Practical Aspects of Offshore Aquaculture System Design from Aquaculture America, so this structure can be said to be operating safely under Indonesian Irregular Wave.

Owing to a stable and porous cage structure, natural gas hydrates can store abundant methane and serve as a potentially natural gas resource. However, the microscopic mechanism of how hydrate crystalline grows has not been fully explored, especially for the structure containing different guest molecules. Hence, we adopt density functional theory (DFT) to investigate the fusion process of structure I hydrates with CH4/C2H6 guest molecules from mono-cages to triple-cages. We find that the volume of guest molecules affects the stabilities of large (51262, L) and small (512, s) cages, which are prone to capture C2H6 and CH4, respectively. Mixed double cages (small cage and large cage) with the mixed guest molecules have the highest stability and fusion energy. The triangular triple cages exhibit superior stability because of the three shared faces, and the triangular mixed triple cages (large-small-large) structure with the mixed guest molecules shows the highest stability and fusion energy in the triple-cage fusion process. These results can provide theoretical insights into the growth mechanism of hydrates with other mono/mixed guest molecules for further development and application of these substances.
