Abstract

The purpose of this study was to determine the physical, mechanical and barrier properties of yam starch edible film. This research used Randomized Block Design (RAK).grouping the cultivar into 2, white and purple water yam. The starch concentration used were 1,33%, 2%, 2,67%, dan 3,33%.The results showed that the two cultivars produced similar properties of edible film.  The concentration of water yam starch affected transparency, thickness, water vapour transmision rate (WVTR) and compressive streght of edible film, but did not affect its solubility in water. The starch concentration of 2.67% was found to be the most appropriate concentration which produce edible film with thickness 0.12 to 0.13 mm, transparency 12.42 to 13.24%/mm, solubility 84.36 to 86.60%, water vapor transmission rate 1.16 x10-2 to 1.08 x10-2 g/sec/m2, and compressive strenght 48.10 to 49.35 N/m2Keywords:Edible Film, Water Yam, Cultivars, Starch concentration

Abstract

Abstract: The purpose of this study was to improve the results and learning process of Genetic subjects in the Biology Education Study Program through lesson study (LS). The research type is descriptive, the sampling technique used purposive. The study sample used 40 students in the sixth semester of class a Biology Education Study Program, Faculty of Education, University of Mataram in academic year 2017/2018. The research data collection technique used observation, documentation, and tests. Data on student learning outcomes and LS-based learning processes were analyzed descriptively. LS implementation in this study consisted of four cycles and each cycle consisted of three stages, namely: planning, implementation, and reflection. Classically the average value of students' cognitive achievement is 82.1% in cycle I and II while in cycle III and IV it increases to 82.67%. Data from LS implementation observation results obtained an average value of 91.63%. The conclusion of this study is the application of LS learning can improve student achievement and learning processes on Genetic subjects in the Biology Education Study Program. It is recommended to other researchers to conduct similar follow-up research in broader research areas, more samples, use more complex research designs, and use more subjects so that more optimal results can be found. Keywords: Lessons Study; learning; genetics; learning achievements; collaborative

Abstract

Abstract: The growth of tin oxide thin film by Aluminum doping and Fluorine has been carried out with the sol-gel spin coating technique. The growth aims to determine the quality of the thin layer formed based on variations in doping aluminum and fluorine. The basic ingredients used were SnCl2.2H2O, while the doping materials used were Al (Aluminium) and F (Fluorine) with variations in dopant concentrations (0, 5, 10, 15, 20 and 25)%. The growth of a thin layer using measured glass (10x10x 3) mm as a substrate. The growth of thin films includes substrate preparation, sol-gel making, thin film making, and heating processes. The growth of thin layer was dripped on a glass substrate with sol-gel spin coating technique at 1 M sol concentration and treated with maturation for 24 hours. The next step is making a thin layer using a spin coater at a speed of 2000 rpm for 3 minutes. After that, the substrate is heated in an oven at 100°C for 60 minutes. The results showed that the transparency level of the tin oxide layer increases with increasing amounts of doping Aluminum and fluorine. Key words: Aluminum, Fluorine, Sol-gel, Spin Coating, Thin Film, Tin Oxide

Abstract

Abstract. This research aims to determine the structure of disaster mitigation learning in elementary schools. It is Research and Development also known as RnD study. This research gives a real-life example of how a teacher can teach and embed the awareness about natural disasters in an uncomplicated and fun way, by using the disaster mitigation model of teaching. The study results in one design of a disaster mitigation model of teaching and a teaching structure implementing a scientific approach on disaster mitigation. This research is based on the development and real-life experience of the researcher team in teaching and doing observation and research on the headmaster, teachers, and the students of Mataram 6 elementary school. It is the pilot project of this research, which in return will be implemented in other schools in the urban, coastal area, as well as the mountainous area in Lombok Island. The result shows that the headmaster and the teachers’ response towards the disaster mitigation model of teaching had been really positive, with only 5% of the teachers claims that they are interested, whilst the other 95% claim that the study is extremely interesting for them. The students were very enthusiastic and active during the learning process. Besides, the claim to have meaningful benefit from this mitigation learning. This thus indicated that this mitigation model of teaching and learning can be used as a guide or reference in embedding the awareness for natural disasters among the school community.

Abstract

One of the biggest pests in rice plants were walang sangit (Leptocorisa acuta Thunb.) Where an attack by sucking plant fluids resulting grain hollow and fragile in the mill. In case of severe attack can reduce rice yields reached 100%. Attempts to control this pest is mostly done with synthetic pesticides. The use of synthetic pesticides can result in damage to the environment. To overcome such effects it is necessary to control that do not pollute the environment. One way to use botanical pesticides, namely yam seed extract. The purpose of this study was to determine the effect on the control of yam seed extract walang sangit (Leptocorisa acuta Thunb.) In rice plants. This study uses a completely randomized design (CRD) with 6 treatments and 3 replications. The treatments were A (0 g / L, B (10 g / L), C (15 g / L), D (20 g / L), E (25 g / L), F (30 g / L). Data mortality observations were analyzed by analysis of variance and continued with DNMRT test. Data were collected for the time of death walang sangit (L.acuta Thunb.) and mortality walang sangit (L.acuta Thunb). The results showed that the death walang sangit (L. acuta Thunb) The fastest is at a concentration of 30 g / L is 4.7 days and the slowest was 12.67 days, whereas the mortality walang sangit (L.acuta Thunb.) is the highest is at a concentration of 30 g / L is 63.3% and the lowest concentration of 0 g / L of 5%

Abstract

Biology Learning Media Course requires students to be able to produce biology learning media. In the previous recovery, students were less creative in producing media for Biology. So students are less able to create suitable media. During this time students do not have the right learning resources in exploring creativity. For this reason, the development of project-based learning based modules is carried out to provide appropriate learning resources and increase student creativity. The purpose of this study was to determine curriculum analysis for the development of media learning modules based on pjbl. Research is a research development using the 4D model at defined stage. Curriculum analysis data were obtained through descriptive analysis. The results showed that 9 materials needed development in the module including communication, learning media, classification of educational media, characteristics of students and their relation to the biology learning media, the role of media in achieving learning objectives, multimedia, photography and video shooting, designing, presenting and displaying, of biology media, media scenarios biology learning. It can be concluded that there are nine materials in developing a learning media module based on PjBL.

Abstract

The synthesis of tin oxide thin films with doping aluminum, fluorine, and indium (SnO2: Al + F + In) by sol-gel spin coating technique has been successfully carried out. This synthesis aims to determine the quality of the thin film formed by adding doping aluminum, fluorine, and indium. The basic material used is SnCl2.2H2O, while the doping material used is AlCl3, NH4F, and InCl3.4H2O. The comparison of the basic ingredients and doping mixture of aluminum, fluorine and indium (SnO2: Al+F +In) used were 100: 0%, 95: 5%, 90: 10%, 85: 15%, 80: 20% and 75: 25%. The synthesis uses a glass substrate with size (10 x 10 x 3) mm. Coating synthesis includes substrate preparation, sol-gel making, film making, and sample heating. The layers that are made consist of 1 to 4 layers. The results showed that the layer formed had a high degree of transparency along with the increasing concentration of the doping material percentage. The higher the doping concentrations of aluminum, fluorine, and indium, the higher the transparency of the resulting layer. Besides, the greater the number of layers, the lower the transparency level of the layers
