<![CDATA[Today, more and more information circulating on the internet that cause more difficulty in finding users desired information because many search engine have not used in understanding the concept of semantic search phrase. Application developed in this research is prototype of semantic search on restaurant data using SPARQL Inferencing Notation (SPIN). Search sentence must follow a rule that must be preceded by direction word (tampil, cari, sebut) and followed by a synonym of class which want to find (restoran, makanan, kategori, lokasi). Every search phrase which entered by user will be translated with tokenization process, stemming, stopword removal (filtering process) and followed by the representation of search sentence using keywords in support ontology (words.owl) thus formed run SPARQL to query data located on restaurant.owl ontology. The test result of this research show that the search application which built have an ability to handle wide variety of pattern of question and got the ratio of recall and precision 1:1, thus meaning that this application has a high effectiveness and efficiency in search result.]]>

<![CDATA[In this research analyzes the connection Wideband Code Division Multiple Access (WCDMA) for uplink and downlink with imperfect sectorization. Because all channels are on the same frequency, so when the active user increases, the performance of system will decrease. In other words, it causes the capacity of system will decrease. In CDMA terminology, the other frequency of Mobile Station (MS) will get effect to the active MS. The co-channel interference can be decrease with splitting the cell into several sectors. It is called the sectorization. But the sectorization can work well because the antenna radiation can’t make the perfect angle and also there is existance of side lobe of radio frequency. The results show, the imperfect sectoration overlap angle between each neighboring sector decreases the capacity system cause more interference to overlapping sector pair. The knowledge gained is to neduce the large overlap angle and we can make the prediction the loss in cell capacity caused by interference.]]>

<![CDATA[This study aims to determine the effect of NaOH concentration and the ratio of monocloro acetic acid with chitosan used in the synthesis process to the degree of substitution and solubility in water. Preparation of carboxymethyl chitosan (CMCts) was carried out by various concentration of NaOH and ratio of monochloro acetic acid with chitosan. The concentration of NaOH used in the alkalination process were 10, 20, 30, 40, and 50% (w/v). The ratio of chitosan: monochloro acetic acid used for etherification were 1:0,5; 1:1; 1:1,5; and 1:2 (w/w). Etherification was carried out at a temperature of 60°C for 2 hours. The results showed that the NaOH concentration of 10-30% (w/v) increased the substitution degree and solubility of produced CMCts. But at concentrations above 30% (w/v) the substitution degree and solubility were decreased. The ratio of chitosan : monochloro acetic acid also affect to substitution degree and the solubility of synthesized CMCts. The higher amount of monochloro acetic acid added to chitosan, the higher is substitution degree and the solubility of carboxymethyl chitosan synthesized in water. The best result was obtained when the ratio of chitosan : monochloro acetic acid were 1:2 (w/w). Within this ratio a 92.05% of yield was resulted with a solubility of 28.05 g/L and a substitution degree of 0.72.]]>

<![CDATA[Cathodoluminescence (CL) is generated by visible light of minerals when they are bombarded with a beam of high energy electrons by a cathode gun. There are two types of chatodoluminescence, i.e., cold CL and hot CL. In the cold cathode microscopic equipment, the electrons are generated by an electric discharge between two electrodes under a low gas pressure, whereas in the hot CL microscope, the electrons are generated by heating a filament (2000-3000°C). This research to propose determine the growth of oolitic limestone’s cement by cathodoluminescence analysis and it’s implication to the engineering properties. Sectoral zoning and chevron-shape growth zoning exist in some coarse-grained calcite aggregates. The sectorial zoning of calcite as reflected by dull to bright CL color indicated as a water level fluctuation during cementation of the carbonate rocks, where the bright color of calcite indicating a shallower depth of water (oxidation) and dull to nonluminescence indicating a deeper level of the water (reduction). The results of this research, oolitic limestone (sample NS-1) showing sectorial zoning (chevron-shape) with at least 6 zonations, and have better engineering properties of other samples, according to SNI. 13-0089-87. Cathodoluminescence analysis is commonly used in the petroleum study, as evidenced in this research can be applied to determine the engineering properties of oolitic limestones in the study area.]]>
