The K-System MAC-1 Trouble-Shooting Trainer: I. Developments, design, and use.

This research is intended to know the effectiveness of quantum reading model by printing media with yen basis in reading concept learning to students of grade 4th elementary school. The problems are: profile of students reading concept competences, the learning process of reading concept, the learning process of reading concept by quantum reading model by printing media with yen basis, the effectiveness of quantum reading model by printing media with yen basis in reading concept learning, and students response of quantum reading model by printing media with yen basis.The trouble-shooting is by use quantum reading model by printing media with yen basis by assumption: if students need to do something therefore will be easily to motivate them in learning and get a better result.Population in this research is Grade 4th Students of elementary school at Sumber Regency, Cirebon. The sample is determined by purposive sampling. The objects in this research are quantum reading model by printing media with yen basis and students reading concept competences. Instruments in this research are sheets of questionnaire, sheets of learning observation, and reading concept competence test. Data that are collected are learning process and data of students reading concept competences. Collected data are analyzed by descriptive statistic analyze.Result of this research are: (1) the competences of students reading concept are good, (2) the learning process are done with students actively, (3) quantum reading model by printing media with yen basis can increase students activity and learning result, (4) quantum reading model by printing media with yen basis is effective to use in reading concept learning, and (5) the students response to reading concept learning by use quantum reading model by printing media with yen basis is very good.Base on the result of this research, get to be proposed for teacher to use quantum reading model by printing media with yen basis to increase students reading concept competence as one of alternative technique in learning, because it is able to motivate, grow the students interest, and increase students creativities to increase students reading concept competences.

White Sugar

Lime salts in the thin juice obtained after juice purification is one of the most important chemical KPI’s (Key Performance Indicator) in beet processing. Too high lime salts content will significantly affect processing costs – particularly energy – due to scaling of heat exchange surfaces thus decreasing heat transfer. In addition, high lime salts are at the origin of turbidity and insoluble solids in white sugar. Therefore, it is of the utmost importance to understand the chemistry behind lime salts in beet processing in order to be able preventing too high lime salts contents in thin juice. This paper will explain the details of the chemistry behind the presence of lime salts. Further, a trouble-shooting guide is included to elucidate the different causes for high lime salts contents and how these causes can be identified, as well as the process measures to reduce the lime salts content in thin juice.
