Abstract

Mangrove has a function as a physical protector of the seashore and also play a role as a habitat of various typesof aquatic fauna. The decaying mangrove stems contain vegetable protein and mixed with animal proteinderived from dead animals in mangrove soil. Proteolytic bacteria play a role in the process of proteindegradation into more simple and soluble compounds. This research aims to: 1) identify species of proteolyticbacteria in mangrove soil, 2) count the Protein Hydrolysis Index on each species of proteolytic bacteria, 3)determine the most potential proteolytic bacteria species to decompose the protein. Soil samples were takenfrom 10 points of mangrove area Margomulyo, Balikpapan. After that, soil samples were diluted in 10-1 to 10-10 and 0,1 mL of each level dilution is inoculated to the NA medium, incubated at 37°C for 1 x 24 hours. Eachcolony sorts were isolated, identified and determined the proteolytic bacteria isolates, then the ProteinHydrolysis Index on the Skim Milk Agar medium were count. The research results showed that: 1) there are 7species of proteolytic bacteria from mangrove soil, 2) the Protein Hydrolysis Index of each species ofproteolytic bacteria ranged from 1.62 to 2.94, and 3) Vibrio parahaemolyticus is the most potential proteolyticbacteria with the Protein Hydrolysis Index is 2,94

Abstract

Abstract- The role of phosphate compounds as limiting nutrients for algae growth in aquatic systems contribute to the occurrence of eutrophication in water bodies. Determination of phosphate was performed by in situ sampling methods technique called DGT (Diffusive Gradient in Thin Films). Prob DGT consists of 3 layers as binding gel, diffusive gel, and membrane filters. With the DGT method, phosphate from sediment pore water will through the diffusive gel and accumulate on the binding layer containing La(OH)3. Samples of sediments taking using sediment cores. Samples taken on 2 (two) locations each 3 points of sampling. Measurement of pH, temperature, and conductivity of water sampling conducted at the site.  Profile presence of phosphate is also linked to the presence of nitrate, manganese and iron in the sediments. Analysis of phosphate, nitrate, manganese and iron made by spectrophotometric method. As a results, at location I, the range of phosphate concentration at point A, B and C are consecutive from 0.0630 to 0.1598 ppm, 0.1306 to 0.2185 ppm and 0.1568 to 0.2082 ppm. Phosphate concentration was increased with increasing depth of sediment, while at location II, the phosphate concentration range at point A, B and C are consecutive 0.1204 to 0.2470 ppm, 0.1479 to 0.3466 ppm and 0.1806 to 0.2603 ppm. From this research we canconclude that the sediments of Brantas River downstream has an important role in the phosphate cycle in which these sediments act as a sink and source of phosphate in the waters. Keywords : DGT technique, sediment, phosphate

Abstract

Indonesia is one of the largest banana-producing countries in the world. Unfortunately, the high demand for bananas has not been balanced with the utilization of banana peels well. Thus, the high production of banana indicates the high amount of banana peel waste produced. On the other hand, tomato production from year to year tends to decrease. According to the Director General of Holticulture (2015), tomato production in 2014 decreased by 76.793 tons. One of the causes is the attack of Ralstoniasolanacearum bacteria that causes bacterial wilt diseases of tomato plants. Vegetable pesticides can come from banana peels because they contain toxin compounds such as flavonooids, sapoin, tannins, etc. Flavonoids will form complex compounds with extracellular and dissolved proteins that can damage the cell membrane of bacteria and followed by the release of intracellular compounds. This study aims to know the process of banana peel extract (Musa paradisiaca) in suppressing the growth of Ralstoniasolanacearum bacteria, which is most effective for inhibiting the growth of Ralstoniasolanacearum bacteria, This research is a  experimental research. the experiment is antibacterial test of banana peel extract on Ralstoniasolanacearum bacteria growth. The design pattern of the study used a completely nested randomized design pattern. The research started with the extraction process with maceration, making of NA and NB media, followed by rejuvenation and suspension of bacteria. After that, making test solution, then test the antibacterial activity with kirby-bauer method and last data retrieval. The results of Antibacterial test results showed positive results can inhibit the growth of Ralstoniasolanacearum bacteria is evidenced by ANOVA of significan value less than 0.05. The Duncan test results show that 100% of Ammon banana is the best to be used for antibacterial. So that banana peel potency to be developed become agent of vegetable pesticide on tomato plant.

Abstract

One of the higher-order thinking skills that is competence in curriculum 2013 is critical thinking skills. However, in the actual learning process the teacher has not yet empowered the students' critical thinking skills. In addition, other aspects such as cognitive styles have also not been considered. This study aims to examine students' critical thinking differences in terms of reflective and impulsive cognitive styles between those using Inquiry Based Learning model with Problem Based Learning model. The research method used is Quasi experiment that is in experiment class I using Inquiry Based Learning model and experiment class II using Problem Based Learning model. The study sample were 64 students of VII B class and VII C class of SMP Negeri 7 Tuban consist of 22 reflective students and 19 impulsive students. To obtain reflective and impulse cognitive style data is used Matching Familiar Figure Test (MFFT). The students' critical thinking data in the two experimental classes as a whole was analyzed using the Independent Samples Test or t-test. While the critical thinking data reflective and impulsive students were analyzed using Mann-Whitney test. The results showed that there is no difference ofcritical thinking between students using Inquiry Based Learning model with Problem Based Learning model. Both are equally able to empower students' critical thinking. However, if examined further by cognitive style, there is a difference between the two experimental classes. Model Inquiry Based Learning is better, because critical thinking reflective students with impulsive students.
