Abstract
The majority of East Java people only use ferns as ornamental plants, even though ferns have potential in the medical field. The fern contains secondary metabolites so they are often called medicinal plants. Anatomical observations supported by histochemical tests can provide the type of secretory structure containing secondary metabolites and the content of secondary metabolites accumulated in these structures. This study began with exploration in the Tahura Soeryo area in June-July 2019. The results of the exploration were Pteris biaurita L., P. maricella V., P. quadriaurita Retz., P. linearis Poir, P. mertensiodes Wild , P. tripartita Sw., P. aspericaulis Wall. ex J. Agardh. , P. longipes D. Don, and P. linearis Poir. The rhizomes and fronds samples were cut across then tested with various types of reagents. Secondary metabolites were found in secretory tissues, vacuoles, and cytosol rhizomes and fronds of parenchymal cells in Pteris.

Abstract
Baluran National Park is one of the national parks with varied ecosystems that have 444 species of plants, 13 of which are ferns. Fern are cosmopolitan plants that can be used as herbal medicines, because they produce bioactive compounds, one of which is phenol. Phenol contributes as a natural antioxidant that can protect cellular components from the oxidation process. Phenol content in different plants has the potential to have different levels. The research objective was to predict the potential of 3 species ferns as natural antioxidant based on phenol levels. Samples in the form of frond and rhizome Pteris linearis Poir, Pteris biaurita Linn. and Christella hispidula (Decne.) Holttum obtained from Baluran National Park. Total phenol content was tested using gallic acid as a standard solution measured by a UV-Vis spectrophotometer. Antioxidant activity was tested using DPPH as a free radical compound. The results showed that the levels of total phenol frond and rhizomes Pteris linearis Poir were 41.74 µg / ml EAG and 21.12 µg / ml EAG; frond and rhizome Pteris biaurita Linn. 65.57 µg / ml EAG and 43.50 µg / ml EAG; leaf (ental) and rhizome of Christella hispidula (Decne.) Holttum were 12.81 µg / ml EAG and 17.94 µg / ml EAG. The antioxidant activity frond and rhizome Pteris linearis Poir were 191.67 µg / ml and 230.03 µg / ml; frond and rhizome Pteris biaurita Linn. 29.70 µg / ml and 80.96 µg / ml; frond and rhizome Christella hispidula (Decne.) Holttum were 99 µg / ml and 36.76 µg / ml. The stronge antioxidant activity was found in Pteris biaurita Linn. and Christella hispidula (Decne.) Holttum, while the weakest was found in Pteris linearis Poir. Based on the results of research on phenolic acid in Pteris biaurita Linn. and Christella hispidula (Decne.) Holttum has the potential to be a natural antioxidant.

Abstract
Land-transmitted worm infections (STH) are a health problem which is prone to occur in children in Indonesia. This worm infection is also one the causes of the high prevalence of stunting in infants in Malang city with an incidence of 3,029 cases. It is assumed that consumption of raw vegetables without proper washing facilitates has been the spread of worm eggs in populations in Malang City. This study was designed to determine the rate of contamination of Soil-transmitted Helminths (STH) Worms in lettuce (Lactuca sativa) in the traditional market of Malang City. A total of 17 vegetable samples from vegetable traders from several markets in Malang were collected for laboratory tests. These samples were tested by microscopic examination to detect the presence of parasites. The results of this study indicated that Ascaris lumbricoides eggs were more dominant in vegetables (82.5%) compared to Ancylostoma duodenale eggs (17.5%). The prevalence of Ascaris lumbricoides worm eggs in Blimbing Market and Big Market in Malang city is higher than the prevalence of hookworm eggs. This study concluded that lettuce vegetables in the traditional market of Malang city were potential for parasitic infections transmission, especially Ascaris lumbricoides worms. Thus, early prevention is needed for these spreading parasites with intensification of hand washing and vegetable washing processes with standardized methods.

Abstract
Jamu gendong, as the typical traditional herbal medicine of Indonesia, has been practised to treat various diseases. However, the contamination of hazardous pollutant which possibly occur will cause the other health poblems. This research observed lead (Pb) content of jamu gendong in three traditional markets in Malang. The jamu obtained from two sellers in each market and covered four replications. Atomic Absorption Spectroscopy (AAS) was used to analyze the Pb contained within jamu gendong. The results informed that the jamu sold in Batu, Belimbing, and Merjosari markets comprised of Pb with the average amount were 0.08 mg/L; 0.18 mg/L; and 0.09 mg/L respectively. This means that the Pb content of these three markets were under the threshold mentioned in SNI 7387:2009, yet they were higher than the standard mentioned in BPOM No.5 year 2018. By considering the results, the awareness of traditional herbal sellers in conducting the hygiene as considerable as their careness about contaminant resources need to be improved, therefore, the jamu gendong sold will be safer to be consumed.

Abstract
Indonesia possesses abundant biodiversity and endemic if compared to biological wealth in other regions in Asia. One form of animal biodiversity in Indonesia is characterized by various types of complex morphological forms, for example in poultry groups. Frizzle chicken is one of the poultry species that have unique morphological characteristics. However, the characterization of morphology and molecular physiology in chicken frizzle in Indonesia is rarely explored until now. This study was conducted to characterize the specific characteristics of Indonesian chicken frizzle by analyzing several parameters such as feathers, scales on the feet and head morphology between local Javanese frizzle chicken and wild-type types. Based on the comparison of the morphology through the parameters above, it was found that there were significant differences between chicken and wild-type frizzle, including curvature, weight, length of fur, and morphology of the head and foot scales. Interestingly, Indonesian frizzle chicken has a more colorful variety of feathers compared to other areas. Thus, the results of this preliminary study are worth-using as the basic frameworks for genetic mapping of species of chicken frizzle in Indonesia. Further research is needed at the molecular level to obtain a comprehensive database of Indonesian frizzle chicken.

Abstract
Information and communication technology (ICT) integration in order to make the learning process interesting and meaningful to students is inevitable. It is a challenge for elementary teachers to engage their students in various activities in classroom and to cultivate their willingness in learning new language. This quantitative study attempts to analyse the effectiveness of ICT integration in fostering students motivation in learning English. A two-set questionnaire was randomly distributed to 270 students from five private elementary schools in Manado City, Indonesia. 210 students out of the 270 completely answered the questionnaire. The collected data was analysed for descriptive and inferential by using statistical tool, such as frequency, percentage, mean, and simple regression. Findings show that ICT integration was effectively implemented and students motivation was high. Moreover, the simple regression analysis revealed that ICT integration significantly impacts students motivation in learning English. The results indicate that students high motivation in learning English resulted when teachers integrate the use of ICT effectively. Based on the results, it is recommended that schools provide sufficient ICT facilities, encourage their teachers to join ICT training program regularly, and involve their students in technology-based learning activities daily.

Abstract
Flies are vectors of disease because flies can transfer bacteria from dirty places to food or the human body. The purpose of this study was to determine the differences in the number of Escherichia coli carried by three types of flies in different location (settlement and garbage) dump. This factorial study involved three types of flies, i.e. the house fly (Musca domestica), green fly (Chrysomya megacephala), and fruit flies (Drosophila sp.). Catching flies is carried out at 02.00 to 05.00 pm for four times a week. Calculation of the number of E. coli using the colony counter in CFU / ml units and two-way ANOVA was chosen to analyze the data that has been obtained. The result, differences in location did not give a significant effect (p = 0.533), while the type of fly had a significant effect on the number of E. coli (p < 0.001). The location and the type of fly also did not show a significant interaction (p = 0.816). Interestingly, Drosophila is the type of fly that carries the least amount of E. coli when compared to the other two types of flies.

Abstract
The internal quality assurance system (SPMI) of the secondary education unit is a quality assurance system that all components in the education unit should implement. SPMI in private Islamic high schools needs to be studied and resolved so that the quality of the process as well as the learning outcomes of students can be equivalent to other schools. This research is aimed to figure out the understanding of Islamic schoool staffs concernng internal quality assurance system, the programs implemented, and the constraints faced. The subjects of this research are teachers, principals, and administration staffs. This research implemented a qualitative approach as its research design. Data were collected through document analysis, questionnaires, and interviews with participants such as, teachers, principals, and administration staffs. Data were analyzed using descriptive qualitative approach, employng the stages of data collection, data analysis preparation, thorough reading, encoding data, encoding text for descriptions and themes used in research reports. The results of the study claimed that the teaching staffs and administration staffs as a whole did not fully understand the SPMI of the secondary education unit. Equally important, the quality assurance programs have not been well organized regarding SPMI to be able to meet the education standards. The main issue occurred in private Islamic high schools was that all school members did neither have a good understanding of SPMI nor a good quality assurance team. Consequently, school programs did not lead to gradual quality improvement to achieve and exceed national education standards. Both sampling schools were in urgent necessity to be given understanding and guidance related to the stages of improving school quality in accordance with the schools vision and mission as well as national education standards. As an initial step, private Islamic high schools need to establish SPMI that is in accordance with the requirements in order to improve the quality of administrative and learning processes.

Abstract. Secondary metabolite of epigallocatechin gallate is a polymeric ester compound from epigallocatechin and gallic acid. This secondary metabolite of epigallocatechin gallate is found in the Camellia sinensis L plant which is bioactive that can be an antioxidant and capable to prevent cancer. The problem of the epigallocatechin gallate-s existence from plants depends on: the height of the land from the sea level, the condition of the environment temperature,and it requires an intensive care and its production level is relatively low. Therefore, the technology of production of epigallocatechin gallate is needed through in vitro culture techniques. This technique is environmentally controlled, is effective in cultivation and only requires a limited area. The purpose of the study was to obtain a secondary metabolite production technique of epigallocatechin gallate through in vitro culture by optimizing the medium and giving precursors. The method to reach the research objectives are: (1) initiation of callus by immersing the explants from leaf pieces on the growth medium that is being added by growth regulating hormones. (2) Stimulating callus culture by giving cinnamic acid precursors. (3) Callus growth testing. (4) Qualitative testing of the epigallocatechin gallate morphology from callus. (5) Quantitative testing of epigallocatechin gallate from callus. The conclusion of this study is that callus products that are composed of epigallocatechin gallate are produced. The implication of this study is that the use of cinnamic acid precursors in the in vitro culture technique of Camellia sinensis over a relatively short period of time can increase callus wet weight

Abstract
The purpose of this research is to investigate the quality of Level of Inquiry (LoI)-based lesson design, which is developed and implemented on science learning in Junior High School through lesson study. The LoI learning model is a further development of inquiry learning with the purpose that teachers and students are more directed in conducting inquiry learning, the higher level in LoI, the less role of teacher and the students are more dominant in the learning process. The methode of this research use qualitative descriptive. The data collected is lesson design that developed by science teacher who is used to following lesson study activities and was analyzed using rubric. Based on the assessment of lesson design rubric with 19 criteria in four domains (instruction, organization, assessment, and learning of inquiry), the results reveal that the strengths consist learning objectives, opening instructions, and instructions that differentiate between groups and individuals as well as organizational aspects, consist defining rules, setting classrooms, group composition is also a clear. The weakness lies in the teacher developing LoI learning, namely at the stage of manipulation and verification.) This finding helps teachers to gain insight into the characteristics of level of inquiry-based lesson design.

Abstract
Drosophilas behavioral studies can facilitate investigations related to human disease as well as various questions about behavioral neuroscience. The aimed of this study was to examine the effect of strains on various Drosophila behavior parameters. The strains used were wildtype, white eyes, and vestigial wings. Larval Crawling Assay, Larval Climbing Assay, Locomotor Assay, and Adult Negative Geotaxis Assay were used as procedures for data collection. Then, the research data were analyzed using a one-way multivariate analysis of variance (MANOVA). The results showed that differences in strains were able to cause differences in Drosophila behavior, especially during the imago phase. The use of wild-type strains is recommended for use as a behavioral study on Drosophila, given the differences in wildtype and mutant behavior recorded in this study. This research is expected to be the basis of Drosophilas behavior study, which is still rarely conducted in Indonesia.

Abstract
Constructivism approach is one of the student-centered learning approaches, students actively build their own knowledge. Social constructivism views that students build new knowledge through their interactions and activities in the classroom, as well as the mediation role of cultural settings and discussion in which the knowledge construction occurs. The purpose of this research is to provide a pattern of analysis students- knowledge construction using Transcript Based Lesson Analysis (TBLA) through Lesson Study for Learning Community. The method of this research is qualitative descriptive. This research involves students from Secondary School who are taught by a science teacher who is used to following lesson study. The learning activities were audio and video recorded. Then recorded were transcribed and analyzed. Dialogue analysis related to the students- knowledge construction was analyzed using TBLA that divided learning process into several segments. The result shows that the profile of students knowledge construction patterns in science learning consists of 3 segments, namely segment 1 which has a circulation pattern, segment 2 which has a circulation pattern and socialization of the last segment 3 which follows the circulation pattern, socialization and simulation. The role of teacher-s questions and students- interaction help students to construct their knowledge.

Abstract
Pollen dispersal can be used to design and manage seed orchards of Mahogany to fit the breeding demand. Pollen dispersal and mating system in mahogany can be elucidated through pollen dispersal pattern analysis based on genetic structure. Microsatellite is a co-dominant genetic marker that has been widely applied for DNA analysis. The objective is this work were to to determine specific primers for parentage analysis in mahogany, to calculate the distance of pollens travel from donor pollen to female recipient, to estimate the frequency of pollination, and to evaluate the proportion of selfing and outcrossing in mahogany. The field activity was done by collecting leaf samples at genetic resource area of Sulawesi BPTH, South Sulawesi, Indonesia. The laboratory activities for genetic molecular analysis were conducted at Biotechnology and Tree Breeding Laboratory, Faculty of Forestry, Hasanuddin University, Indonesia. Results: The study indicated that the suitable primers for parentage analysis were sm05, sm18, and sm48. Pollens could travel up to 83 m apart from the evaluated female parents, and the highest frequency of pollination was 22 at 20 to 30 m. The proportion of outcrossing was 95% which indicated that mahogany trees in this evaluated area tend to outcross pollinate. Highly variable microsatellite markers have facilitated a direct genetic approach to measuring gene flow based on parentage analysis.

Abstract
There are two main factors that have triggered a low level of Consumer Empowerment Index (IKK) in Indonesia, namely the lack of public knowledge about regulations and institutions related to consumer protection, and complaints that are not common among consumers. Improved education can take advantage of the involvement of many Consumer Protection NGOs in various regions by prioritizing strengthening consumer empowerment in eight sectors, namely clean water, energy, health, medicine and food, housing and property, transportation, financial services and e-commerce. This study aims to analyze the implementation of consumer protection education programs in improving the IKK. The method of approach taken in this research is a normative juridical approach and is supported by empirical research. The results of the study show that on average consumers in Indonesia are still helpless with an IKK score of 40.41 ("capable" level) in 2018. This means that Indonesian consumers are only limited to being able to use their rights and obligations as consumers to determine the best choice and to use domestic products. IKK is an index that measures the level of consumer empowerment in Indonesia. The higher the value of the IKK shows that consumers in Indonesia are increasingly empowered.

Abstract
Microbes are capable to dissolve phosphate. Phosphate is the second essential component after N, which has a crucial role in photosynthesis and root development. A microbe that found around root area is the Bacterium Bacillus strain. This bacterium was isolated from peppers- roots. The purified isolates were quantitatively evaluated for their capacity to dissolve phosphate using Pikovskaya liquid medium with Ca3(PO4)2 as phosphate source. Meanwhile, production of gibberellin hormone was measured using Borrow et al (1995) method. Here, we reported levels of phosphate and gibberellin produced by the bacteria ranged from 19.0 up to 58.8 µg/L and 5.81 up to 12.79 µg/L, respectively. This results indicate that the Bacillus strain isolated from peppers- roots and root area can be utilized as plant growth-promoting bacterium.

Abstract
The development of the use of preparations with natural coloring has been carried out a lot, but there is no one that shows optimal concentration. The purpose of this study was to determine the optimal concentration of Erythrina crista-galli L. flower extract as a natural dye based on the parameters of the quality and stability of the preparation. The type of research used is experimental research. This research method through several stages: extracting, diluting extracts with various concentrations (30%, 50%, 70%, 90%, and 100%), until making maceration preparations. Data collections were conducted twice, where the first and second take has an interval of one semester. Kruskall Wallis is used as a technique for analyzing data from research results. Both in the first and second observations, the concentration of 70% always produce the best quality preparations. Thus the Erythrina crista-galli L. flower extract has the potential as natural staining in histological preparations.

Abstract
This study aims to provide a profile of students VNOST as a basis for the development of didactic designs that can teach aspects of technology in high school chemistry learning. This study involved 196 students who were randomly selected from grades XI from one of the secondary schools in Bandung. The modified VNOST questionnaire was used as a research instrument consisting of four aspects, namely: 1) the view of science, the purpose of science, the purpose of scientific research, 2) the view of technology, 3) the view of scientific knowledge and scientific theory, and 4) the view of the relationship between science, technology, and society. Each statement in the questionnaire was classified as "Realist", "Has Merit", and "Naïve". The data obtained were analyzed on each item using a frequency distribution to the students VNOST group. "Realist" VNOST is used as a good indicator of VNOST views. The results revealed that most students have VNOST at the "Has Merit" level, which means that students views on the nature of science and technology are still lacking and need to be improved. For this reason, educators need to integrate science and technology in science learning in schools.

Abstract
Bawean is an island with 11,872 ha of area, located about 140 km from Gresik Districts, East Java. Bawean become one of the marine tourism destinations, especially in Noko island which one of the small island areas lived by ± 700 peoples. Noko island located 4 km east from Bawean surrounded by coral reefs. Ship traffic and fishing activities by local communities potentially damage the coral reefs ecosystem. The study aims to determine the key species and identify the extent of coral reefs damage. The study was descriptive explorative using Belt Transects as far as 150 meters from the farthest coral reefs boundary in two different locations. Data analyzed by Important Value Index and standard criteria damage for the coral reefs. The results was found 87 coral reef species and covering at location 1 was 10.41% /m2 with category 5. Location 2 was 92% /m2 with category 5 and according to the standard criteria damage to coral reefs was on very good category. Acropora palifera is the key species with the highest density and frequency, location 1 with density of 10.41% and frequency 98%, location 2 by 18.5% density with frequency 93%.

Abstract
Abstract The implementation of family planning (KB) programs by the government due to an increase in the rate of population growth using modern contraceptives can cause quite dangerous side effects. This study aims to determine the effect of pulutan leaf decoction (Urena lobata L.) on the length of the estrus cycle of mice (Mus musculus) Balb-C strain as a substitute for modern contraception. Mice were grouped into 6 treatment groups with 4 replications. P0 group as a control (0% concentration), P1 (5%), P2 (7,5%), P3 (10%), P4 (12,5%), and P5 (15%). The administration of pulutan leaf simplicia (Urena lobata L.) was carried out for 15 days orally (gavage). Determination of the estrus cycle was carried out by the mouse lavage technique every day for 15 days of treatment. The length of the estrus cycle is determined by calculating the length (days) between the estrus stage (initial treatment) until the next estrus stage (counted 4 stages). The results of the one way ANOVA test and the Duncan test revealed that there was an effect of pulutan leaves (Urena lobata L.) decoction on the estrus cycle length of the mice (Mus musculus) Balb / C strain (p <0.05). The administration of pulutan leaf simplicia can extend the estrus cycle of mice (Mus musculus) starting at a concentration of 7.5%.

Abstract
Introduction: Malathion is one of organophosphate pesticides that can cause intoxication when used inappropriately. Pulutan (Urena lobata) is medicinal plant used to treat some diseases empirically and pre-clinical study has already proven its efficacy as antioxidant and anti-inflammatory. The study aims to evaluate the potential of Urena lobata (U. lobata) leaf extract on blood glucose level and hemoglobin (Hb) in the juvenile and adult of zebra fish (Danio rerio) exposed by malathion. Methods: The object study using juvenile and adult of zebra fish (Danio rerio) which divided into each 2 control group and 3 test group (n=4). The leaf of U. lobata was extracted by decoction methods therefore it was diluted into 125 mg/L, 250 mg/L and 500 mg/L. The animal test was exposed by herbs for 40 days concomitant with malathion 5 mg/L. Blood glucose level and Hb were measured using a commercially available glucometer and Hb meter. All data are expressed as the mean ± SD and analyzed with one-way anova and continued with LSD (p<0.05). Results: The administration of U.lobata leaf extract at dose of 125 mg/L and 500 mg/L able to inhibit the decrease of Hb level more and less 10 % and 20 % respectively compare to malathion group (p<0.05) both of on juvenile and adult of zebra fish (Danio rerio). Whereas the blood glucose level was decreased by 40%, 60% and 40% (p<0.05) respectively on juvenile that were given U. lobata at dose of 125 mg/L, 250 mg/L and 500 mg/L, meanwhile on adult of zebra fish were reduced 60%, 50% and 50% respectively (p<0.05). Conclusion: U. lobata leaf extract is able to inhibit the increase of blood glucose level and the decrease of Hb level both of on juvenile and adult of zebra fish (Danio rerio).
