Abstract

This study aims to examine the use of English in the Biology handbook through a learning approach based on Content Language Integrated Learning (CLIL) to increase the Technological Pedagogical Content Knowledge (TPACK) for prospective teacher students in the Biology Education Study Program at the University of Mataram. This research was conducted using a quasi-experimental approach with multiple group pre-test and post-test patterns. The test subjects and units of analysis were all second-semester students taking English for Biology courses at the FKIP Biology Education Study Program in the 2021/2022 academic year consisting of 6 classes, namely A, B, C, D, E, and F. TPACK data were analyzed using the N-gain. The N-gain test is used to measure the difference between the post-test and the pre-test. Based on the results of data analysis, it is known that there is an increase in students' TPACK ability to get N-gain values of 91%, 56%, 67%, 64%, 66%, and 61% for classes A, B, C, D, E, and F. The average value of N-gain for TPACK of biology education students is 68, which is quite effective. Therefore, it can be concluded that the English handbook through a CLIL-based learning approach contributes quite effectively to increasing the TPACK of prospective Biology teacher students.

Abstract

Research has been carried out on making green mussel shell adsorbents to absorb Cu and Cr metals. The study of making green mussel shell adsorbents was carried out by thermal activation using a furnace. The results of the activated adsorbent were characterized using FTIR and SEM-EDX. Furthermore, the adsorbent was used to absorb Cu and Cr metal by using several variations, namely variations in the temperature of the adsorbent activation, adsorbent weight, pH, and contact time, and knowing the kinetic model by determining the reaction order. The results obtained from the characterization of green mussel shells contain elements of Ca, about 67.56% at an activation temperature of 500 °C and 67.34% at an activation temperature of 900 °C. The optimum conditions for Cu metal adsorption by green shell adsorbent were obtained at an activation temperature of 500 °C, using an adsorbent of 1 gram under pH 10 and a contact time of 40 minutes. Whereas for Cr metal absorption, the activation temperature was 900 °C, the mass used was 1.5 grams with pH 7 and the contact time was 40 minutes. The adsorption kinetics model of green mussel shells adsorbent on Cu and Cr metals followed pseudo-second-order.

Abstract

PowerPoint-iSpring is one of the technology-based media needed in learning. Giving guiding questions is expected so students can find concepts independently through exercises and questions in the media. This study aims to develop PowerPoint-iSpring learning media integrated with prompting questions on stoichiometry class X SMA. The development model used was the Plomp model, which was carried out until the stage of prototype III formation due to time and research staff limitations. Researchers self-evaluate media that has been designed to determine the completeness of the components of a media. Then an assessment was carried out by experts consisting of four chemistry lecturers at FMIPA UNP and two chemistry teachers at SMAN 10 Padang. Three students of SMAN 10 Padang carried out the individual evaluation stage (one-to-one evaluation) with different abilities. The research instruments used were validity questionnaire sheets and interview sheets. The validity questionnaire was analyzed using the Aiken V formula with a category ≥0.79 valid and if <0.79 ​​is invalid. The research results found that the average value of Aiken V PowerPoint-iSpring learning media on stoichiometry material for content validity was 0.88, and construct validity was 0.87. Technical quality validity was 0.93, with each validity being categorized as valid. The results of the one-to-one evaluation obtained from 3 students were good. The suggestion is that it would be better if these media were small so they could be installed on a device without requiring much space. The images that covered the writing explaining the material would be better if the layout was improved.

Abstract

Antioxidant compounds are vital for the body. An imbalance in the body's levels of free radicals and antioxidants will cause oxidative stress and cause disease because free radicals will damage the surrounding molecules (lipids, proteins, and nucleic acids), causing damage to tissues and cells. Today many studies are interested in using natural antioxidants in food, beverages, cosmetics, and therapies derived from plants. Centella asiatica is a plant often used as a source of antioxidants because it contains active compounds such as terpenoids, flavonoids, polyphenols, tannins, carotene, and vitamin C, which have antioxidant activity. In addition to containing 78% menthol, mint leaves contain resin and tannins, which are several polyphenolic antioxidants that prevent or neutralize the effects of free radicals. Antioxidants are compounds that can delay, slow down, or inhibit oxidation reactions and fight free radicals. The results showed that the antioxidant activity of the combination of Centela asiatica leaf extract and mint leaf extract based on the results of the analysis showed that it was included in the strong category.

Abstract

Shallots have long been cultivated by farmers intensively because shallots have a high economic value, so they become a source of income for farmers. Shallots are annual plants belonging to monocotyledonous plants that have multi-layered tubers formed from layers of leaves that enlarge and unite with cylindrical leaves. The soil fertility level influences shallots' growth, development, and production, requiring additional fertilizers. One of the good fertilizers used is vermicompost. Vermicompost is an organic fertilizer containing microbes and elements required for plant growth. This study aims to determine vermicompost's effect on shallot growth (Allium ascalonicum L.). This study used a completely randomized design with ten replications. The treatment levels consisted of P0 = 0 grams of vermicompost per 1 kg of soil, P1 = 40 grams of vermicompost per 1 kg, P2 = 80 grams of vermicompost per 1 kg of soil, and P3 = 120 grams of vermicompost per 1 kg of soil. Parameters observed were the number of leaves, number of tubers, plant height, wet weight, dry weight, and chlorophyll content of shallot. The research data were analyzed using ANOVA and Duncan's Multiple Range Test at the 5% level. The results showed that the addition of vermicompost had a significant effect on the number of leaves and chlorophyll content of the shallot but had no significant impact on the number of bulbs, plant height, wet weight, and dry weight of the shallot.

Abstract

This study aimed to test the antimicrobial activity of endophytic bacteria and fungi isolates of soursop (Annona muricata L.) in inhibiting the growth of E.coli, S. epidermidis, and C. albicans. The stages of the research were the isolation of endophytic bacteria, antimicrobial assay, and characterization of potential endophytic bacteria and fungi. Endophytic microbial was isolated from leaves, bark, and root of soursop taken from Praya, Central Lombok. The agar diffusion method was used in the antimicrobial activity assay. Characterization was carried out on endophytic microbes with antimicrobial activity based on colony morphology, Gram staining, and biochemical tests. The antimicrobial activity test results showed that none of the endophytic bacteria and fungi isolates had intense activity inhibiting the test microbes' growth. Isolates with code DN3, DNX, and AKRX had medium activity against E. coli, isolates with code AKR1 had medium activity against S. epidermidis, and isolates with code DN2 AKRX had medium activity against C.albicans. The research results showed that the endophytic bacteria from soursop plants could inhibit the growth of test microbes in the weak to moderate.

Abstract

Universitas Sulawesi Barat (Unsulbar) launched its primary Learning Management System (LMS) named E-learning of Universitas Sulawesi Barat or often called “E-learning Unsulbar” in 2020 (https://elearning.unsulbar.ac.id/). Implementing E-learning at Unsulbar is one of the university’s efforts to maximize distance learning, especially during the COVID-19 pandemic. A study was conducted to evaluate E-learning readiness to measure the readiness of new students of the Biology Education Study Program towards the E-learning implementation. It is a quantitative descriptive study using a survey method adapted from a questionnaire developed by Akaslan and Law. The respondents were 77 new students from the biology education class of 2020 in the odd semester of 2020-2021. The measurement adapts three main stages, i.e., readiness (technology, people, institutions, content), acceptance, and training. The result showed that the readiness of new students for E-learning Unsulbar for technology and training factors were 3.1 and 3.3, respectively. It was categorized as not ready, which means that there needed to be more readiness of students’ internet infrastructures and academics who need training in using E-learning Unsulbar. Meanwhile, the scores for the factor of people, institutions, content, and acceptance were 3.8, 4.2, 3.85, and 3.9, respectively, and categorized as ready to be implemented. This result is an evaluation material for the university in determining the right policy for implementing E-learning Unsulbar.
