Abstract

Aeromonas hydrophila (A. hydrophila) are classified as zoonotic and opportunistic bacteria. Natural immunostimulants such as herbs are biodegradable and safe for the environment and host health. There has been no systematic review of using these natural ingredients to treat or prevent A. hydrophila infection. This review aims to demonstrate the role of herbs and probiotics as antibacterial, antioxidant, and immunostimulatory against A. hydrophila infection. This study deployed systematic and comprehensive literature from PubMed, Google Scholar, and Scopus from 2012 to 2022, with keywords: A. hydrophila, herbal, probiotics, antioxidant, immunomodulator, antibacterial. Data are obtained from journals, proceeding of research results, excluding article reviews. The review results indicate that the utilization of these two ingredients (herbs and probiotics) is potential to prevent A. hydrophila infection in animal models with variation action mechanisms and dose administration. However, an inappropriate combination of herbs and probiotics leads to the development of resistance and toxicity profile, thereby requiring further research to standardize such combination prior to application for humans or animals.

Abstract

Mamaq by the ancestors of the Sasak people was an activity of chewing betel nut, lime, betel leaf, and tobacco, and ending with shrinkage. Betel leaves contain glycosides, steroids, triterpenoids, flavonoids, tannins, and anthraquinones. These compounds contain antimicrobial activity that can fight Staphylococcus aureus, Escherichia coli, and Candida albicans fungi. Meanwhile, whiting is a strong base because it has a pH of 11-12.5. This is because in the mouth there is saliva which can maintain a pH of around 6.8. Saliva contains phosphate buffer solutions H2PO4- and HPO42-. And gambir contains a component in the form of catechins which function as antioxidants and antibacterials. The purpose of this research is to study philosophical values, especially epistemology, which investigates the origin, and composition of methods and knowledge related to mamaq philosophy and natural science concepts, especially chemistry, and compounds, and what reactions occur in the mamaq process that has not been revealed. The study uses the library method. From the results of thestudy, it was concluded that in addition to the philosophy in the ingredients for mamaq it can also be described the chemical compounds contained in the ingredients for mamaq, starting from whiting, green betel leaf, gambier, and areca nut.

Abstract

Science learning is still not integrated with the surrounding environment so that students tend not to be able to recognize the local wisdom of their area. Even though science learning contains local wisdom, it can increase students' love of local culture, creating contextual and meaningful learning. To overcome this, research was carried out through the development of a science e-book containing gamelan's local wisdom based on STEAM-POE. This development research aims to (1) determine the validity of a science e-book containing gamelan's local wisdom based on STEAM-POE (2) find out student’s love local culture. This study uses the Thiagarajan 4D development model (Four-D Model), which consists of four stages, namely the definition stage, the design stage, and the development stage. The dissemination stage was not carried out, this research was only limited to product feasibility testing. The research design used was the one-group posttest-only design. The sample in this study was class VIII E, totaling 32 people. The collection techniques used were questionnaires and documentation. The results of the material expert validity test showed that the science e-book containing gamelan's local wisdom based on STEAM-POE was declared very valid with an Aiken's V value of 0.992 and the validity of the teaching material expert showed that the science e-book containing gamelan's local wisdom based on STEAM-POE was declared very valid with Aiken's V score of 1.0. Students' love of local culture after using the science e-book containing local gamelan's local wisdom based on STEAM-POE shows a score of 3.266 in the very good category. Students' love of local culture also gets a variable score of 52.5 which is included in the high category.

Abstract

This study aims to analyze the impact of environmental biogeography on point mutations in Kosta and Lakor goat breeds as local Indonesian germplasm using the GDF9 Exon 1 gene sequence. A total 43 folicle samples of Kosta and Lakor goats which collected in Serang regency and Lakor island were analyzed. To isolate the total genome of the samples, the tissue isolation method was used. The polymerase chain reaction (PCR) method was used for amplification of the exon-1 region of the GDF9 gene with two pairs of primers. Analysis of genetic variation and single nucleotide polymorphisms (SNP) using MEGA software version X. Multiple alignment results showed that there are 2 nucleotides that have mutations, but not encode different amino acids. This results indicates that the mutation has association with litter size of two breeds. This finding shows that Lakor goats have polymorphism i.e SNP g.54C>T which is significantly associated with litter size. The analysis of GDF9 gene showed that all samples from the Two local Indonesian goat breeds (Kosta and Lakor) are  monomorphic. But, although both are monomorphic, geographical isolation still contributes to genetic drift within and between populations.

Abstract

Indonesia is a country with very high biodiversity and is known as Mega Biodiversity. In Indonesia found about 450 species of Anura representing about 11% of all species in the world, and 28 species ofwhich 28 live in West Java.  Anura animals have a pattern of calling behavior that is essential for mating: males produce call-up behavior that attracts females and, in some species, represents the extent of their territory. Research on frogs and toads is considered necessary considering the absence of more detailed data on the bioacoustics of these frogs, especially in the West Java area, so that variations and patterns of anura sounds are known in the Telaga Warna Nature Reserve and Nature Park (CA-TWA) area and can make scientific contributions in information on variations and sound patterns owned by anura animals in terms of anura conservation in Indonesia.  This research was conducted from month March-December 2018, located in Telaga Warna Nature Reserve and Nature Park, Bogor, West Java.  Call the recording every 6:00 p.m. to 11:00 p.m. each night during the sampling period.  The number of anura species in the villa and swamp areas is more abundant than the lake area, and the presence of Pearl maroon frogs (nyctixalus margaritifer) found in the villa and lake areas, while the Bufo melanotictus type that likes to live in the lake area. It can be seen that the villa and swamp areas are still maintained vegetation by looking at the medium density of the canopy. Steeper slope conditions help the flow of nutrients from the soil due to the erosion process and settle in flat to gentle areas. The density of the canopy in the area helps maintain the surface temperature of the land with a stable land surface temperature ranging from 15 – 21 0C.

Abstract

The low learning motivation of students is a classic problem that often occurs in the teaching and learning process and has an impact on learning outcomes. One way that can be used by teachers in solving motivational problems and student learning outcomes is by applying innovative learning media such as e-modules combined with guided inquiry learning models. This study aims to determine differences in learning motivation, differences in increasing learning outcomes and the relationship between motivation and student learning outcomes through the application of e-modules combined with guided inquiry on the material structure and function of plant tissue. This research is quantitative with experimental research methods and research design Pre-test Post-test Control Group Design. The population in this study were 214 students from class XI IPA at SMAN 1 Darul Imarah and SMAN 1 Peukan Bada Aceh Besar. The research sample consisted of 121 students who were divided into two classes, namely the control class and the experimental class. The parameters of this study are the motivation and learning outcomes of students. The instrument for measuring motivation used 36 items of the ARCS motivational questionnaire, while learning outcomes were measured using 40 multiple choice tests. The increase in learning outcomes is calculated by the N-gain formula. Data analysis to see differences in motivation and differences in increasing learning outcomes used Mann Whitney test analysis, while analysis of the relationship between motivation and learning outcomes used Pearson's Product Moment correlation analysis. The results showed that there were differences in students' learning motivation (p <0.05), there were significant differences in increasing learning outcomes (p <0.05), there was a significant relationship between motivation and student learning outcomes. The conclusion of this study is that there are differences in motivation and differences in the increase in student learning outcomes after applying learning using e-modules combined with guided inquiry.

Abstract

The native plant of mainland Asia, Durian, presents a considerable opportunity to be used as animal feed due to the high by-product production, with almost 70% of every durian fruit being waste. This presents an excellent opportunity to repurpose durian skin and seeds as animal feed. An experiment was conducted to evaluate the impact of durian by-product on the productivity and physiological condition of kacang goats. The research was conducted from September to November 2020 at the Experimental Cage owned by CV. Prima BREED, Palu City, Central Sulawesi Province. The research cages were stage cages, with a size of 2 x 10 m, and one animal was placed in each cage. A total of 18 Peanut goats were divided into 3 treatment levels and 6 replications according to a completely randomized design. The study found that the nutritional intake of durian by-product in the form of rind and seed flour as much as 0.5% in the feed affected the carcass percentage, the amount of red blood cell, hemoglobin level, and hematocrit value but had no effect on body weight gain, dry matter consumption, feed use efficiency, carcass weight, weight and percentage of non-edible carcasses, body temperature, respiration frequency, pulse frequency, and white blood cell count of kacang goats. This indicates that the utilization of 0.5% durian by-product (seeds and rind) in feed did not have a negative effect on the productivity and physiological condition of kacang goats, making it a viable option for animal feed.

Abstract

This study explains chemistry students' perceptions of online-based chemistry learning during the Covid-19 pandemic. The descriptive quantitative survey method was used for the research. The research was carried out at 16 universities in Indonesia in the Chemistry Education Study Program involving 311 students. A survey technique with a Likert scale was used to collect data. The survey form was created using a Google Forms questionnaire, making it easier for students to access. The data analysis technique utilized in this study was to determine the percentage of data from each questionnaire indication from the disseminated Google form, then interpret it into a data presentation score and analyze each indicator in depth. The results showed that students' perceptions of online-based chemistry learning in chemistry education study programs at 16 universities in Indonesia were in poor criteria, this was obtained from the percentage score on the online enjoy learning indicator by 50%, the content presentation strategy indicator 40%, online media indicators used are 65%, indicators are constrained when online learning is 20%, student readiness indicators are 21% and online learning evaluation indicators are 60%. This research is expected to be a reference for evaluating various parties in online-based chemistry learning, especially regarding students' perceptions of fun learning activities. This study also discusses the problematic tendencies of online-based chemistry learning, namely (1) students' motivation decreases due to boring learning, (2) students' understanding of concepts is reduced because the presentation of learning content is less than optimal, (3) students' readiness to participate in online learning is very lacking because have no previous online learning experience. As a result, the findings of this study can be used as evaluation material in analyzing and developing online learning models during the Covid-19 pandemic.
