Waterfall Model

This study aimed to develop and test the feasibility of a smart greenhouse prototype media that is used as a planting medium with an automatic watering system. The method in this study was research and development using the waterfall model. In order to test the feasibility, the prototype was validated with material expert validators, media expert, and farmers. The questionnaire instrument was compiled based on Walker and Hess instrument. The results of the research found are as follows: the results of feasibility research by media experts has an average score of 4.35 with the category "very feasible", assessment by experts the material has an average score of 4.4 with the category "very feasible", and the assessment of the user has an average score of 4.06 with "feasible". The purposed controlled system of smart greenhouse and as a media for farmers was validated. Our results demonstrated that the smart greenhouse is suitable media to help farmers cultivating the tomatoes plant.

The Relationship

This study was conducted to determine the relationship between nursing students’ awareness and attitudes towards research and developments and their academic motivation levels. This descriptive and cross-sectional study was carried out with students from nursing department of faculty of health sciences of a university in Turkey (n=460). Data were collected using the questionnaire form which included the socio-demographic characteristics of those students, “Nursing Students’ Attitudes to and Awareness of Research and Development within Nursing Scale” and “Academic Motivation Scale”. Data were analyzed using percentage, mean, Pearson’s correlation analysis, Student’s t, and One Way Anova tests. The mean age of the students was 20.56±1.52. 81.1% were female and 28.7% were in their first year. The average score of the Nursing Students’ Attitudes to and Awareness of Research and Development within Nursing Scale was 120.54±17.46. The students’ mean score on intrinsic motivation subscale was 57.20±13.45, on extrinsic motivation subscale was 61.96±11.50 and on amotivation subscale was 10.12±5.87 in Academic Motivation Scale. The level of the students’ awareness and attitudes towards research and developments has a positive correlation with the levels of their intrinsic and extrinsic motivation and a negative correlation with the level of their amotivation (p<0.05). The average score of the Nursing Students’ Attitudes to and Awareness of Research and Development within Nursing Scale were statistically significantly different in the gender, the status of their following scientific publications and the positions they wanted to work after graduation (p<0.05). It has been determined that the students have high level of awareness and attitudes towards research and development, and their academic motivation levels affect their awareness and attitudes towards research and development.

Abstract This development research generally aims to (1) develop interactive multimedia-based learning media for Private Vocational School Imelda Medan, (2) to know the assessment of media experts and material experts on learning media, and (3) to know the feasibility of learning media based on the assessment of media experts and material experts. The method used in this research is Research and Development. This research was conducted at Imelda Private Vocational School Medan. Research and Development Results: (1) This development research process is carried out with several stages adapted from the borg and gall version development research model simplified into 4D. There are stages such as: Define, Design, Development, and Disseminate. Define stage includes definition, design stage includes storyboarding, development stage includes development of interactive multimedia-based learning media, validation of media experts and material experts, as well as revision of learning media from media experts and material experts and disseminate stage covering the trial stage. The target of this research is the Expert Lecturer of Medan State University. Testing of interactive multimedia by material validators showed that multimedia learning resulted both in material validation with an average score of 4.52 and for media validation with an average score of 4.59. Then obtained the conclusion that developed media is worth to use. Keywords : Interactive Media, Interactive Multimedia Abstrak Penelitian pengembangan ini secara umum bertujuan untuk (1) mengembangkan media pembelajaran berbasis multimedia interaktif untuk SMK Swasta Imelda Medan, (2) mengetahui penilaian ahli media dan ahli materi terhadap media pembelajaran, dan (3) mengetahui kelayakan media pembelajaran berdasarkan penilaian ahli media dan ahli materi .
