Metode Rational Unified Process untuk Pengembangan Aplikasi Web dan Mobile (Studi Kasus Sistem Informasi Tanaman Obat Daerah Gorontalo)

The insufficiency of information to the society regarding the utilization and benefits of the Gorontalo area of medicinal plants led to a lack of utilization of medicinal plants in this area. Besides cheap, Gorontalo's medicinal plants can also overcome various kinds of diseases. Nevertheless, the data of medicinal plants had not been well managed and had not been documented and stored digitally. This research aims to develop information systems in web applications and mobile Gorontalo's medicinal plant's data. RUP (Rational Unified Process) using the concept of a Unified Modelling Language (UML) is used in the method of designing a system that consists of a Use case diagrams, Activity diagrams, and Class diagrams. Programming language using PHP with the concept of OOP (object oriented programming) as a backend for web applications and the IONIC framework as a frontend for mobile applications. The results indicate that the application can organize the data of medicinal plant and also display the data and search for medicinal plants based on specific disease

THE EFFECT OF TEMPERATURE IN TETRADESMUS OBLIQUUS

The ever growing demand of energy generation and distribution has been one of the concerns of governments and the focus of research institutions.  Likewise, how to supply the energy demands necessary for the development of nations having the lowest environmental impact possible has also been studied. Biofuels have been pointed out as an alternative for that energy challenge, since their use reduce the carbon footprint of industries and vehicles. Biofuels can be obtained from microalgae with the advantage of not competing for space with corn, sugar cane or other crops for food industry. Even though attractive, the biofuel production from microalgae presents some challenges, as for example the separation process required to obtain microalgae biomass. The culture is very diluted and the dewatering must be efficient, low cost and cause no damage to the cell. With the intent to address this issue, the herein paper presents a study of an alternative way to increase flocculation efficiency according to the temperature of the culture with the potential to improve the filtration efficiency in a continuous process. An increasing in the flocculation temperature from 20°C to 60°C increased the flocculation efficiency from 97.79% to 98.64%, using ferric chloride as a flocculant agent

Observation of Dirac surface states in the noncentrosymmetric superconductor BiPd

Funding from the MPG-UBC center and the Engineering and Physical Sciences Research Council (EP/I031014/1 and EP/L505079/1) are acknowledged. This work was supported by the DFG within projects STA315/8-1 and BE5190/1-1.Materials with strong spin-orbit coupling (SOC) have in recent years become a subject of intense research due to their potential applications in spintronics and quantum information technology. In particular, in systems which break inversion symmetry, SOC facilitates the Rashba-Dresselhaus effect, leading to a lifting of spin degeneracy in the bulk and intricate spin textures of the Bloch wave functions. Here, by combining angular resolved photoemission (ARPES) and low temperature scanning tunneling microscopy (STM) measurements with relativistic first-principles band structure calculations, we examine the role of SOC in single crystals of noncentrosymmetric BiPd. We report the detection of several Dirac surface states, one of which exhibits an extremely large spin splitting. Unlike the surface states in inversion-symmetric systems, the Dirac surface states of BiPd have completely different properties at opposite faces of the crystal and are not trivially linked by symmetry. The spin-splitting of the surface states exhibits a strong anisotropy by itself, which can be linked to the low in-plane symmetry of the surface termination.PostprintPeer reviewe

Mapping of Submerged Aquatic Vegetation in Rivers From Very High Resolution Image Data, Using Object Based Image Analysis Combined with Expert Knowledge

The use of remote sensing for monitoring of submerged aquatic vegetation (SAV) in fluvial environments has been limited by the spatial and spectral resolution of available image data. The absorption of light in water also complicates the use of common image analysis methods. This paper presents the results of a study that uses very high resolution (VHR) image data, collected with a Near Infrared sensitive DSLR camera, to map the distribution of SAV species for three sites along the Desselse Nete, a lowland river in Flanders, Belgium. Plant species, including Ranunculus aquatilis L., Callitriche obtusangula Le Gall, Potamogeton natans L., Sparganium emersum L. and Potamogeton crispus L., were classified from the data using Object-Based Image Analysis (OBIA) and expert knowledge. A classification rule set based on a combination of both spectral and structural image variation (e.g. texture and shape) was developed for images from two sites. A comparison of the classifications with manually delineated ground truth maps resulted for both sites in 61% overall accuracy. Application of the rule set to a third validation image, resulted in 53% overall accuracy. These consistent results show promise for species level mapping in such biodiverse environments, but also prompt a discussion on assessment of classification accuracy
