The design experiments showed that this context can stimulate students to understand their knowledge of the idea of dilation and reflection in transformation geometry. This study describes how the motifs of bamboo woven made a real contribution for ninth-grade students to understand the concept of dilation and reflection in transformation geometry.

The research method used is design research consisted of three stages: preliminary design, teaching experiment, and retrospective analysis. This context was used as the starting point in the learning process by applying the Pendidikan Matematika Realistik Indonesia approach. Therefore, this study aims to design the dilation and reflection in transformation geometry learning trajectory using the motifs of bamboo woven. Yet, Indonesian students still have difficulty applying mathematical concepts to solve problems related to everyday life, such as dilation and reflection in transformation geometry. Thus it can be concluded that the recommendations of Primbon only partially affect the abnormal return on the Indonesia Stock Exchange.Cultural diversity around students can be integrated into learning mathematics in the classroom. Abnormal return from groups of stock recommended by Primbon only presented on Monday aggressive stocks group from 09.00 to 11.00. This study uses event study methodology to ob-serve abnormal return of stocks recommended by Primbon that grouping into defensive stock called “rahayu” and aggressive stock called big luck (rezeki besar) on certain time in a day. This research examined other issues which is a belief of traditional calendar called Primbon among Javanese in Indonesia. Studies of cultural event, Ramadhan effect. The research observed and tested cultural phenomena called Primbon as a calendar effect on abnormal return. Type of this study is conclusive descriptive using intraday trading data. The purpose of this study is to examine Javanese lunar calendar (Primbon) effect to abnormal return on Indonesian Stock Market.
