The objective of the study was to examine different increasing student knowledge between demonstration method with phantom and film viewing about examination physical to pregnant.
This study used quasi-experiment with pre-test and post-test designs (Pratomo and Sudarti 2006). This study used two groups: the group demonstration method with phantom and the other group treated with the film viewing. Variables were used to explain problems in this study consisted of an intervening variable was demonstration method of the phantom (X1), film viewing (X2) and the dependent variable that student knowledge (Y). The population of the study was 20 students in Prodi Kebidanan Curup Poltekkes Kemenkes Bengkulu Semester III 40 students in 2011. The criteria of the participants in this study were students Prodi Kebidanan Curup Poltekkes Kemenkes Bengkulu Semester III got a grade of C (65-69) in Askeb I (20 people). On September 10, 2010, before starting this study, the researcher had done the validity and reliability test of the questionnaire to 15 students (participants) Semester III Prodi Midwifery Curup beyond the study participant.
Based on Table 1, it showed 11 question items used in the questionnaire. On October 18, 2010, the researcher asked an agreement with a participant. Then participants were divided into two groups: the first group of 10 people, as a participant for treatment method with a phantom demonstration, then the second group of 10 people for treatment through film viewing of the physical examination in pregnant women.
The research process was Group I got demonstration method with a phantom. Group II got film viewing as the treatment in Poltekkes Bengkulu Prodi Kebidanan Curup. Before demonstration with phantom methods and film viewing, all participants give a briefing on procedures for these activities; then they did pre-test for 15 minutes with a questionnaire of 11 questions to measure student knowledge about the physical examination in pregnant women.

Bivariate analysis was performed with t-test, classified into some categories with figures with a 95% confidence level.
|Variable||Pre-test Mean||Post-test Mean||Mean Difference||T||p value|
Table 4 showed that demonstration method was better than film viewing in increasing knowledge of students.
Comparison of the average value of student knowledge before and after being treated through demonstration method with a phantom method and film viewing showed that there were differences between the mean before and after was being addressed, namely in the form of an increase in the average number of students essential knowledge. It was showed from the mean difference, an increased understanding by demonstration method with phantom 1.6 while through film viewing 0.9, it showed that a demonstration method with phantom was better than movie viewing in increasiing knowledge of the student about examination physical to pregnant women.
Physical examination of pregnant women was conducted on the body from head to toe by standard operating procedures (Hidayati 2010). Demonstration method was a method of teaching by way of demonstrating goods, events, rules, and the order to do an activity (Syah 2005). In a demonstration of the methods, it was usually applied by using assistive devices such as small objects, images, laboratory equipment devices, including phantom. Demonstration method with phantom had some advantages, including the following: a) through the process of demonstration, the occurrence of verbal can be avoided, because the students were directed to the lesson material; b) the learning process would be more interesting, because students not only heard but also saw events that happened; c) by way of directly observing, the students would have the opportunity to compare between theory and reality. Students would be convinced of the truth of learning materials (Hidayati2010).
Phantom was medium that could be objected for mocking three dimensional of some real objects that were too big, too far, too small, too expensive, too little, or too complicated to be brought into the classroom (Sudjana and Riva 2002). Phantom had some benefits including the following: a) natural learning process in the classroom; b) improve the efficiency of the learning process; c) maintain the relevance of the subject matter with the aim of learning; d) asswast in the process of learning. Based on Kamus Besar Bahasa Indonesia (2005) film viewing was: a) movie, thinner membranes made from celluloid to a negative image that would later become a portrait or a positive picture that would play in the cinema; b) the film was a story (story) live image. According to Hasan (2010), the strengths of film media were: a) leaving a message that could be received more evenly by the students; b) very careful to explain a process; c) overcoming the limitations of space and time; d) better realistic, repeatable and terminated in accordance with the requirements; e) leaving a deep impression, which could affect students' attitudes.
The results of this study consistently was in line with research conducted by Pulungan (2007), showing that there was a significant difference between knowledge before (12.60) and after (1962) the extension services with the mean difference of 7.02 (p-value 0.05). This was supported by the opinion of Amalia (2010) that stated health education with the methods of demonstrations might affect the knowledge of knowing it at early adulthood when it compared with the airing of the film, with the results of a participant of 72 people. The result of T-test on knowledge was 2.750 with significant value 0.008; T-test results on attitudes was 0.228 with significant amount 0.820 and the T-test results on the behavior was 2.057 with significant value 0.043.
The results of this study were consistent with the results of research Partiyah (2010) stated that 16 students (88.9%) felt an increase in knowledge and only 1 (5.56%) student who did not have the influence after teachers used instructional media in the form of screening. The results showed that in the implementation of the teaching and learning of Islamic religious education, teachers with the use of instructional media worked out well, indicated by the students that were more interested in following the lesson. The students got more active, more easily to understood, motivated, and didn't feel bored. Many factors that supported the lesson included mastery of the material with which motivated the child's condition, accuracy in choosing the media, while the limiting factor was the lack of enough attention from parents and media limitations that were provided by the school.
Demonstration method with phantom was better to increase the knowledge of students about physical examination in pregnant women when compared with the film viewing. The suggestions in this study were: a) Educational institutions: preferably in the practice of the learning process, the educational institutions, increasing the number of small groups in the classroom while doing a demonstration with a phantom method. It aims to improve the understanding of students knowledge; b) For further research, other researchers can develop this study by assessing the learning styles of students, which affects students' experience in the learning process
