On Equitable Irregular Coloring of Jelly Fish and Coconut Tree Graph

Coconut sugar is a local sugar from the blossoms of a coconut tree. It has been considered a healthy sugar due to its low glycemic index. There is an attempt to add other sugar to it to lower the cost. Thus, this research aimed to identify Thai coconut sugar and to establish models for predicting the moisture content of coconut sugar by using FT-NIR spectroscopy. Thai coconut sugar samples were purchased from local grocery stores in four provinces, online, and the community market. Their moisture contents were varied and equilibrated for 24 hrs prior to the measurements of moisture and FT-NIR spectra. The results showed that FT-NIR spectra of Thai coconut sugar differ from sucrose, glucose and fructose at the absorbance spectrum of 5379-5011 cm-1 . FT-NIR spectroscopy of 54 known moisture samples of Thai coconut sugar was used to obtain a model to predict moisture content. The predicted equation, using the PLS technique with the Spectrum Quant program, was found to give a standard error of prediction (SEP) 0.077% (less than 0.10%), indicating a non-destructive method of accurately and precisely predicting moisture levels in the coconut sugar. The results obtained suggested that FTNIR spectroscopy has the potential to be used as a tool to identify Thai coconut sugar accurately. It can rapidly predict the moisture content in the sample which will be useful in quality control standards.

The purpose of this research is isolation and characterization to find potential bacteria which can produce the most optimal ethanol from the Arak Bali industry in Karangasem Regency, Bali. Bacteria were isolated by exposure method in open air using selective media Zymomonas Sucrose Medium (ZSMA) with the addition of nystatin as much as 0.18 g / L as an antifungal then samples were taken at three different points in one Arak Bali production location, namely the distillation place, the fermentation room for roomie, and the place of taking coconut juice under the coconut tree and the variation of time is 15, 30, and 60 minutes of exposure. Gas checking is done on the bacteria obtained to select its ability to produce ethanol. The results of the scanning of 11 best isolates using UV-visible spectrophotometry were fermented on 500 mL ZSM media for 10 days. BM1-CP14 is the best isolate to produce total ethanol of 15.33 mL through the fermentation process. The results of the characterization of BM1-CP14 isolates were Gram-positive bacteria in the form of bacilli, anaerobic and non-motile bacteria. The results showed that bacteria isolated from open-air also can produce ethanol. Keyword: ethanol, Arak Bali, airborne bacterial exposure, isolation, characterization, UV-Visible spectrophotometry

Set Up

With a view of increasing the productivity on CNC machine tools one of the main solution is to reduce, as much as possible, the auxiliary time consumed with the set-up and replacement of the tools and work pieces engaged in the machining process. Reducing the total time of the tool changing process by the automatic tool changer system can be also achieved through minimizing the number of movements needed for the actual exchange of the tool, from the tool magazine to the machine spindle (the optimization of the tool changing sequences). This paper presents a new design method based on the tree-graph theory. We consider an existing automatic tool changing system, mounted on the milling and boring machining centre, and by applying the new method we obtain all the possible configurations to minimize the tool changing sequence of the automatic tool changer system. By making use of the method proposed we obtain the tool changing sequences with minimum necessary movements needed to exchange the tool. Reconfiguring an existing machine tool provided with an automatic tool changer system by making use of the proposed method leads to obtaining the smallest changing time and thus high productivity.
