Abstract. Research on "Application of Cross Puzzle Media on the Material of Colloid Systems to Improve Learning Outcomes of Students Grade XI SMA Negeri 3 Banda Aceh". This study aims to determine learning results, activities and responses of learners after studying the materials colloid system with the implementation of TTS media. This study used a qualitative approach and the type of experimental research. Subjects in this study were students of class XI MIA 7 as an experimental class and class XI MIA 6 as the control class. Data collected by observation activities, attitudes, the TTS media, the LKPD, tests and questionnaires. The instruments used were observation of sheet activities, attitudes, the TTS media, the LKPD and test questions as well responses of learners. The results showed that the classical completeness learning outcomes of students in the experimental class knowledge aspect 84.37% higher than the control class that is 43.75%. The average value of the activity of students in the first meeting and the second using the TTS media is 91.66% greater than the control class using the LKPD is 75.42%. Positive response of learners to use the TTS media obtained by percentage of 92.27% is included in the excellent. Based on the results of this study concluded that the application of the TTS media the materials colloid system can accomplish the learning outcomes of students, increases the activity of learners, and give a positive response to the learning activities.Keywords: TTS, learning outcomes, activities, colloids.

Experimental research on effectiveness of the magnetic fluid seals for rotary shafts working in water This paper presents course of research on ferro-fluidal seals used in water. The tests were carried out for a hydrophobic magnetic fluid and specially selected profiles of sealing lips at various linear velocities in sealing unit. Though the tests were preliminary their results showed that the research on application of magnetic fluids to seals working in liquid environment should be continued. From the point of view of development of ring drives the most important advantage of ferro-fluidal seals is their smallest drag as compared with seals of other types.

This paper reviews the evidence for a secondary transfer effect of intergroup contact. Following a contact’s typical primary reduction in prejudice toward the outgroup involved in the contact, this effect involves a further, secondary reduction in prejudice toward noninvolved outgroups. Employing longitudinal German probability samples, we found that significant secondary transfer effects of intergroup contact exist, but they were limited to specific outgroups that are similar to the contacted outgroup in perceived stereotypes, status or stigma. Since the contact-prejudice link is bidirectional, the effect is inflated when prior prejudice reducing contact is not controlled. The strongest evidence derives from experimental research. Both cognitive (dissonance) and affective (evaluative conditioning) explanations for the effect are offered.
