PENGARUH PERBEDAAN WARNA CAHAYA LAMPU PETROMAKS TERHADAP HASIL TANGKAPAN IKAN UMPAN DENGAN ALAT TANGKAP PUKAT PANTAI (BEACH SEINE) DI TELUK AMBON BAGIAN DALAM

This study attempts to identify the effects differences in the hues lamp oil-based lamps given to successful operations fish bait by the use of a get the beach ( seine seane ) on the gulf of ambon part in north conducted on 20 Oktober to 25 December 2018, the data was undertaken at night from pm 20.00 wit to 05.00 wit closer to waiheru coastal village ( i station ), coastal village and hunut station ( ii ) in as many as 10 times using two units of a get the beach ( seine seane ) and two a light color, treatment color the each green orens design and color on the random group ( RAK ). Remedial than 10 times there are three kinds of fish baited with the details are as follows: fish tatari ( rastrelliger spp ) 5927 the tail ( 44 % ) , heavy 10,42 kg ( 47 % ) , fish puri ( encrasicholine heteroloba ) the number of 6419 the tail ( 48 % ) , heavy 8,01 kg at 42 % and fish make ( sardinella sp ) the number of 1013 the tail ( 8 % ) , heavy 1,57 kg ( 11 % ) .With a total of the fish 13.395 a tail with heavy 20 kg with details of the fish a fish bait treatment with the greatest percentage in a lamp shade the color of orans namely 7745 a tail with heavy 9.99 kg and then treatment a lamp shade of a green color to the total number of 5614 a tail with heavy 9,98 kg .The results of the analysis of the results of the diversity of types of catch a fish bait , show that the two a light shade of have a which do not exhibit a significant difference or both the color of the light dicobakan the same - alike will be good for use in an effort to arrest a kind of small pelagic fish especially the types of a fish bait.

Detection and Characterization of Ignitable Liquid Residues in Forensic Fire Debris Samples by Comprehensive Two-Dimensional Gas Chromatography

This study covers an extensive experimental design that was developed for creating simulated fire debris samples under controlled conditions for the detection and identification of ignitable liquids (IL) residues. This design included 19 different substrates, 45 substrate combinations with and without ignitable liquids, and 45 different ILs from three classes (i.e., white spirit, gasoline, and lamp oil). Chemical analysis was performed with comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS) for improved separation and compound identification. The enhanced peak capacity offered by GC×GC-TOFMS allowed the use of a target compound list in combination with a simple binary decision model to arrive at quite acceptable results with respect to IL detection (89% true positive and 7% false positive rate) and classification (100% correct white spirit, 79% correct gasoline, and 77% correct lamp oil assignment). Although these results were obtained in a limited set of laboratory controlled fire experiments including only three IL classes, this study confirms the conclusions of other studies that GC×GC-TOFMS can be a powerful tool in the challenging task of forensic fire debris analysis.
