However, the existence of this plant is rare due to lack of cultivation by local community because of long period of germination of dragon’s blood seeds (8 months 1 year). This researches aimed to discover the effect of given natural cyokinins (coconut milk) and synthetic (atonic) towards dragon’s blood germination. Results shows that given synthetic cytokinins (atonic) at 1,5% with soaking period for 48 hours and natural cytokinins (coconut milk) at 75% at 48 hours soaking period able to stimulate fastest germination resulting only two days while soaking period towards dragon’ss blood haveno influence towards germination. The highest germination found on 1% atonic concentration and 75% concentration of coconut milk.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134413144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To get the information of an object, the principle of reflection in physics was used . Sunlight comes to the earth surface and an object or wave is brought to the object, then the object reflects back the wave spectrum corresponding to the object characteristics into space and captured by the sensor as a data source that will be processed using a computer. Thus, the reflected object characteristics will be known. The results of the study: -prove that remote sensing can be used to observe the desired earth surface, -and there is environmental changes by looking at the greenness index (NDVI) and surface temperature (LST) and, -there is land curvature.

Feed and drinking water are given ad libitum. Treatment was given for 35 days. On the 36th day all chickens were cut, for observation of body weight, percentage of carcass, liver weight, and meat cholesterol. The data obtained were tabulated and analyzed using one-way ANOVA and continued with LSD test using SPSS 21.0. The results showed that the higher giving of wake-up leaf flour reduced the weight of the liver and cholesterol levels of meat. Supplementation of 20% PF flour in feed does not affect broiler chicken body weight.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124049478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this, one of the efforts to complete it is the development of effective teaching materials. Excellent teaching materials will help students in solving problems in learning including deep conceptual understanding. Many misconceptions occur for students who have completed introductory physics courses. Whereas in the introductory physics courses there are many major branches of physics. Conceptual understanding is a part that cannot be missed in the whole of physics learning. Weak understanding of the concept will affect the completion of mathematical physics questions. Sometimes students can solve a physics problem that is mathematical but does not understand the concepts contained in it. One method of solving physical misconceptions in students is to use peer learning methods whose activities are arranged in instructional materials developed based on Algodoo. This method is expected to reduce the misconceptions that occur for students who take Introductory Physics courses during their first year of college.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128791801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
