Abstract

The difference in the amount of salt excretion in mangrove species occurs due to differences in Casparian strips (Gasparini strips) in the root endodermis. Mangrove Avicennia sp has salt-secreting glands. These glands secrete NaCl salts through an active process. The purpose of this study was to analyze the salt content in the roots and leaves of the mangrove secreter Avicennia Sp. in Gotowasi Village, East Halmahera. This research was designed based on the type of case study (case study) and quantitative descriptive using a purposive sampling method and research experiments conducted on independent variables. Root samples were taken at the research location, while the salt content measurement was carried out at the UNKHAIR Biology laboratory using a refractometer. Salt content data were analyzed by means of potential water pressure, namely the sum of potential pressure and osmotic pressure. The results showed that the salt content of roots and leaves of Mangrove secreter Avicennia sp in different water conditions. The results of the Salt Content measurement of Avicennia sp roots at high tide conditions at station I, namely 35‰ (per mile), and station II, namely 25‰. Furthermore, the results of the measurement of salt content in water conditions at low tide at station I the average value is 21‰ and station II is 17‰. The measurement results of salt content in Avicennia sp mangrove leaves at high tide conditions at station I is 15‰, while at station II it is 21‰. Furthermore, the results of measuring the salt content in water conditions at low tide at station I, the average value obtained is 25‰. While at station II it is 30‰.

Abstract

Abstract,This research is the development research by the following steps: (1) Research and initial data collection, (2) planning, (3) Preparation of Initial Product, (4) initial tests. (5) Repair initial products, (6) The field trials, (7) Improvement of operational products, (8) Test operations, (9) Improved end products, (10) Product Dissemination. The data source in this study consists of 3 experts of product design and including a material expert. And there are 40 students who divided into two classes, 20 students in the class IX-3 as the control class and the others 20 students in the class IX-1 as the experimental class in SMP Negeri 6 Ternate. The purpose of this research is to develop IPA tutoring package and to increase the study results of the students after tutoring. The test results shows the development of IPA tutoring package is very well and worth used in tutoring with the results of 80% and product design test result has reached 83% with a very decent qualitfications and categories very well. For the study result of students at the operational test reveals that there is a different average in learning outcomes of students who use IPA tutoring package to learn and do not use the package. This is evidenced by sig.2-Tailed value < 0.05 where the value of 0.00 <0.05. The results of teacher responses in operational tests of the IPA tutoring package is very well with a percentage of 98%. Then the results of the students responses to learn IPA tutoring package is very good as well with the percentage of 91%. This research has resulted that IPA Tutoring Package facilitate teachers and students to learn better.
