Abstract
Field trip is one learning method that provides direct experience for students to be able to interact with the surrounding environment. In Biology class, field trip is one of the keys when students want to observe natural phenomena. This study aim to identify student multiple intelligences and scientific reasoning profile as a reference in designing a field trip for high school students on ecosystem topics. The subjects in this study were 55 students from two classes of 10th grade in even semester with purposive sampling. Data collection using Teen MIDAS (15-19 years) to identify student multiple intelligence and TOLT instruments for student scientific reasoning profile. The results of this study indicate that there are 3 types of intelligence that are most prominent, namely naturalistic, interpersonal and logical-mathematical as for future reference to dividing groups based on these three intelligences. In addition, student scientific reasoning which was found to be at 66% formal operation, 22% transitional and 12% concrete operation stage indicated that the design of the field trip that had to be prepared to have a level of analysis with one or two variables. There are still many students who have not been able to solve combinatorial reasoning. Thus it can be concluded that the best field trip design for this group of student is a design with worksheet that featured naturalistic, interpersonal and logical-mathematical with no more than two variables involved.

AbstractMangrove forest in Indonesia one of which is located in West Tanjung Jabung District Kuala Tungkal Jambi Province is the ecosystem of mangrove Pangkal Babu. This ecosystem is one of the local potentials of this area. Many mangrove ecosystem provide benefits. The many benefits of this mangrove ecosystem cause the ecosystem to suffer damage so there is an effort to overcome it. The solution is a local potential based education. Local potential based education is an education based on the surrounding environment so it can create more meaningful learning. Biology is a subject that can be developed to improve environmental knowledge and a good attitude for the environment. The method used is an exploratory descriptive method with data retrieval techniques in the form of interviews and observations. Data processing techniques carried out descriptively. These results are seen from the condition of abiotic, biotic, adaptation, and interaction. Observed abiotic conditions are temperature, salinity, pH, and DO/dissolved oxygen. The abiotic condition found 19 species of mangrove plants and several types of animals. This local potential can be used as a source of learning biology, especially on ecosystem material.

Published: March 2021

Abstract
Student textbooks were generally limited with examples and were also seldom found relevant to students’ daily lives which often caused biology learning not to run contextually. Meanwhile, there were many contexts around students that could be used as references or learning resources. One of the local potentials found on the east coast of South Sumatra was Musi estuary. There were many potentials such as the wealth of biotic components and their abiotic factors. Therefore, we needed teaching materials that could complete the use of textbooks in schools, this aimed to help students more easily understand concepts through relevant contexts. The development of teaching materials used the ADDIE approach; analysing, designing, developing, implementing and evaluating. Making alternative teaching materials for Musi estuary ecosystem had arrived at the development stage followed by evaluating each of the previous stages. This research was using the validation questionnaire of the National Education Standards Agency (BSNP) including aspects of the feasibility of content, the feasibility of language, the feasibility of presentation and the feasibility of graphics. The teaching material has validated by 3 experts and 3 high school Biology teachers. Based on the results of material validation by experts it was obtained an average score of 3.13 (77.38%), and high school biology teacher 3.33 (83.17%), which then concluded that the alternative teaching material of Musi estuary ecosystem was discovered eligible to be used as a supplementary of biology textbooks on grade X for ecosystem learning material.

Authors: Rustaman N Y 
Published: March 2021

Abstract
Pro-contra about concept mastery in STEM learning inspired this study to encounter conceptual change and STEM-project at the same time using R and D at different educational (junior, senior, university) levels. System thinking was chosen as medium to combine conceptual change and STEM learning, as it was found as part of Scientific Literacy in PISA and STEM approach, and as a UNESCO competency for Education for Sustainable Development. Groups of students from different levels of education were involved as research subjects. Certain consideration in choosing the biology topics and pre-posttests (concept mastery and system thinking skills) was administered for all level. Using system thinking oriented learning material it was reported that 7th graders can understand (plant & animal) cells structure well, no misconception for new concepts (prokaryote, plant tissue system), as they experience EDP in STEM-project and produce cell models. Conceptual change in high schools still resulted in misconception when the pre-post tests were taken once, but not for pre-post tests taken in each meeting. Topic choice and specific learning material for STEM based learning with system thinking oriented are very important to have complex system topic that enable to develop three types of system thinking.

Published: March 2021

Abstract
Each material has different electrical characteristics. One of the electrical characters of materials is impedance. This characteristic used to specify the components of the material. To determine the impedance value of materials frequently used method is the injection of current through a pair of electrodes. This study will make effective electrode designs. The electrode designs used are circular with 1mm, 5mm, and 15mm diameter variations, with 3mm, 7mm, and 11mm configurations. The electrode material used is a copper plate (PCB). The results of the graph on mineral water show that the 11mm configuration produces a logarithmic graph. This result is due to the total impedance of mineral water affected by the resistance component and capacitance at the electrode. The measurement of sugar solution shows that 5mm diameter is more sensitive than 15mm diameter. Then the effective electrode design for impedance measurement is 5mm diameter with an 11mm configuration.
