Peningkatan Profesional Guru Tentang Pemahaman Pembelajaran Terpadu dalam Muatan IPA Di SD Gugus I Kecamatan Kuranji Padang

Integrated learning has 10 types, one type of integrated learning that is applied in SD is the webbed type integrated in the 2013 curriculum. For this reason, an understanding of the teacher is needed in implementing web type integrated learning in schools. The purpose of this study was to determine the level of teacher understanding of integrated learning in the webbed type of science content in Cluster I Region I, Kuranji District, Padang City. This type of research is qualitative. Based on the distribution of a questionnaire containing 20 statements divided into three parts, it was found that 50% of the teachers understood the types and applications, 84% of the teachers understood the strengths, and 67% of the teachers understood the shortcomings of the webbed type of integrated learning. So the teachers in Cluster I Region I, Kuranji District, Padang City already understand the webbed type integrated learning.

Application of Naive Bayes Algorithm to Analysis of Free Fatty Acid (FFA) Production Based on Fruit Freshness Level

Cooking oil is a basic need for everyone who is used to process food ingredients. The use of cooking oil repeatedly and continuously by heating at high temperatures can increase the free fatty acid levels in the oil. The more the oil is reused, the higher the free fatty acid content. Testing the levels of FFA in oil can be done using the FFA test, because FFA can affect the selling price of CPO when it is marketed. In addition, FFA affects the levels of free fatty acids of CPO. This study aims to determine the analysis of FFA production in palm oil products based on the level of freshness of the fruit. The research was conducted by classifying data mining using the Naïve Bayes Algorithm. The Naïve Bayes algorithm was used to determine whether FFA production had an effect on fruit freshness, fruit quality and fruit soiling. The research was conducted using RapidMiner Studio 9.10 tools. The results of the research from the distribution table show that the value of the FFA attribute obtained 2 conditions, namely super conditions and normal conditions. Where each of these attributes is influenced by the variables of fruit freshness and fruit quality. Probability accuracy results from 60 training data and 40 testing data used are 92.50% for super FFA conditions

TOXICITY TEST OF EXTRACTS OF THE FOUR SEA CUCUMBER (FAMILY HOLOTHURIIDAE) FROM EAST PENJALIRAN ISLAND, SERIBU ISLANDS, JAKARTA BASED ON THE BRINE SHRIMP LETHALITY TEST (BSLT)

Sea cucumber is one of the marine bioactive compounds resources . The properties of the bioactive compound are biologically shown by their functions as anticancer, antifungi, hemolytic, and immunomodulatoryt. The purpose of this research is to predict (determine) the toxicity level of the extracts of Actinopyga miliaris, Holothuria leucospilota, Bohadschia argus, and Bohadschia marmorata collected from Penjaliran Timur Island, Seribu Island National Park Jakarta. The method used in this research is Brine Shrimp Lethality Test (BSLT). The result of this research showed that all of the extract from those species are active in BSLT, indicated by LC50 values of less than 1000 μg/ml. Bohadcshia argus is highest active species indicated by LC50 value 69,254 μg/ml. Water fraction of H. leucospilota’s crude extract is the most active fraction indicated by LC50 50,968 μg/ml.Keywords: Brine Shrimp Lethality Test, Crude Extract, Fractionation, Family Holothuriidae, Sea Cucumbe

ANTIOXIDANT ACTIVITY OF THE ASCIDIAN MARINE INVERTEBRATES, DIDEMNUM SP.

Objective: This study aimed to determine the antioxidant activity of samples of the ascidian Didemnum sp. collected from Seribu Islands, Jakarta.Methods: Antioxidant activity was tested using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Didemnum sp. was extracted into methanol andthen fractionated using n-hexane, ethyl acetate, and water. Fractions with the highest antioxidant activity were further fractionated using acceleratedcolumn chromatography.Results: The concentration of sample that reduced the DPPH radical by 50% (IC50) in a methanol extract of Didemnum sp. was 105.10 μg/mL. The ethylacetate fraction had the highest antioxidant activity (IC50 of 90.804 μg/mL). The most active fraction obtained from accelerated column chromatographyfraction had an IC50 of 86.35 μg/mL. The compounds contained in the most active fractions were alkaloids, saponins, steroids/triterpenoids, andglycosides.Conclusion: The methanol extract of the ascidian Didemnum sp. exhibited antioxidant activity. Fractionation of the Didemnum sp. extract showed thatthe ethyl acetate fraction had the highest antioxidant activity. Further, fractionation of the ethyl acetate fraction by accelerated column chromatographyshowed that fraction VI had the highest antioxidant activity. The most active fraction contained alkaloids, steroids/triterpenoids, saponins, andglycosides

DNA Barcode Characterization of Chocolate Hind Grouper (Cephalopholis boenak) in Several Indonesia Waters with the New Sequences Record from Madura Island

This study aims to describe the molecular characteristics of DNA barcodes in chocolate hind grouper (Cephalopholis boenak) in Indonesian waters with new sequence records from Madura Island waters. Partial sequences of the cytochrome c oxidase 1 (CO1) gene were successfully obtained from two samples of C. boenak in Madura Island waters. In contrast, the other sequences were obtained from the BOLD system database, covering the Islands of Bali, Lombok, and Ambon waters. The overall molecular analysis involved 10 C. boenak sequences with a length of 625 bp. The results indicated that the population of C. boenak in Indonesia waters has high genetic diversity, as evidenced by the value of haplotype diversity (Hd) = 0.956 and nucleotide sequence diversity (Pi) = 0.01746, in which the population is distributed into eight haplotypes. Results of phylogenetic tree reconstruction of neighbor-joining and maximum-likelihood indicate similar topology. The branching of NJ and ML phylogenetic trees of C. boenak in Indonesia waters is grouped into two geographical clades. Clade 1 with the subpopulations of the waters from Madura, Bali, and Lombok Islands. Clade 2 with the subpopulations of the waters from Ambon Island. The results of the median-joining network reconstruction depicted a similar topology with both phylogenetic trees

Effects of Biochar and Chromolaena odorata Liquid Fertilizer Enriched with Sodium Bicarbonate on Soil and Muskmelon (Cucumis melo L.)

Biochar is an organic material instantly made by burning wood into charcoal by pyrolysis, which can meet the high demand for an organic material that cannot be available in a short time. The study aimed to determine the effect of biochar and Chromolaena odorata liquid fertilizer (CLF) enriched with Sodium bicarbonate on soil pH and Muskmelon (Cucumis melo L.) productivity. The research was conducted from December to February 2019 at the field station of Tamansiswa University, Padang. The study was carried out in a factorial experiment with 2 treatment factors arranged in a Completely Randomized Design, consisting of three replications within treatments. The data obtained were analyzed using the F test at 5%, followed by the Least Significant Difference (LSD) test at 5%. The results showed that there was an interaction effect of Biochar and CLF application on reducing the soil pH. Among all treatments, the application of 2 t.Ha-1 biochar combined with 50 ml.L-1 CLF + 0 g.L-1 sodium bicarbonate resulted in the highest growth rate and yield of muskmelon in Ultisols soil
