Abstract

The COVID-19 pandemic has changed the patterns of learning in schools. This study aims to determine: (1) the pattern of implementation of online Biology learning at SMAN 1 Kediri; (2) students' perceptions of online Biology learning at SMAN 1 Kediri; (3) differences in students' perceptions of online Biology learning at SMAN 1 Kediri based on grade level; 4) differences in students' perceptions of online biology learning at SMAN 1 Kediri based on gender. This type of research is exploratory, descriptive research. The population in this study were students majoring in science at SMAN 1 Kediri. The research sample consisted of 137 students. The sampling technique used was stratified random sampling. Data analysis was carried out using qualitative and quantitative approaches (calculating categories, percentages, and median tests). The results show that the implementation of online Biology learning at SMAN 1 Kediri used WhatsApp Group (WAG) and Google Classroom (GC) media. Students' perceptions of online learning of Biology subjects during the Covid-19 pandemic varied, both positive and negative. Online learning provides flexibility and easy access to learning resources, but there are also difficulties in student-teacher interaction and understanding of the learning material. Students' perceptions of online learning are similar between grade levels and genders.

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.

Abstract

Student Worksheets a media in the form of sheets containing tasks and activities that students must carry out, which are useful in supporting the learning process, one of which is in the material on the Structure and Function of Plant Tissues so that students can be active in the learning process. An assessment instrument is needed for the Student Worksheets. For this reason, this study aimed to measure the instrument's validity and reliability for using Student Worksheets as a learning media. This study used Research and Development (RND) methodology with an instrument in the form of a Student Worksheets measurement questionnaire consisting of three constructs: product design, material feasibility, and language feasibility. This research was carried out by involving seven teachers from several schools. Data were obtained by distributing the questionnaire via a Google form from September to October 2022 by obtaining prior consent from the respondents. The data obtained were quantitative, then analyzed using SPSS version 29 in the form of Alpha Cronbach analysis. The results of the test show that the validity of the instrument data meets the valid and reliable criteria with each Cronbach Alpha value per construct, namely Product Design (0.795), Material Feasibility (0.712), and Language Feasibility (0.712). Therefore, this study shows that the developed instrument meets the use requirements in developing Student Worksheets media students. Thus, stakeholders and teachers can use this instrument to develop media, particularly Student Worksheets, whereas further researchers can use this instrument to measure media before the study.

Abstract

The Open Educational Resources (OER) media is used in distance lectures in Statistical Physics to increase student learning resources. However, OER needs to support distance lectures optimally. Therefore, a case-based E-task is needed as an alternative solution. This study investigated the effect of using e-Task on student involvement in Statistical Physics lectures. This type of research is quasi-experimental. This research was conducted in semester 2021.2 at the Open University, involving a sample of students taking statistical physics courses in the Physics Education program. The data analysis technique used was the independent sample t-test, with the data being normally distributed and homogeneous. Based on the results of the independent sample t-test analysis above, it can be concluded that the experimental class has a higher score than the control class, namely the attendance percentage is 100, the discussion percentage is 80.8, and case-based e-task solving is 7.3. It shows that there is a significant difference between the experimental class and the control class. Thus the use of e-task can increase student involvement in Statistical Physics lectures.

Abstract

Testing of optical fiber-based sensors using the imperfection method to detect alcohol contents. The sample results from mixing alcohol and distilled water to produce eight samples with an alcohol content level from 0% to 70%. The greater alcohol content causes the output power of the sensor to decrease due to the increase in the refractive index of alcohol content around the sensor. An increase in the refractive index of alcohol content causes power losses to increase, resulting in lost light intensity being transmitted in optical fiber-based sensors. Power losses are increasing to produce the best characteristics of the sensor. The best sensor is shown in the Gamma configuration at imperfection 3 with a sensitivity value of 0.346 µW/%. The imperfection method is suitable for determining the characteristics of optical fiber-based alcohol detection sensors because it has a high sensitivity.
