Abstract

The transition to online learning since the start of the Covid-19 pandemic has forced all parties to respond quickly to the use of information technology. Various applications are used in the learning process. Of course, this was followed by the digitization of learning tools, including the Laboratory Management course held by the Science Education Study Program of the University of Sarjanawiyata Tamansiswa. Learning tools are needed to accommodate Course Learning Outcomes (CLO), one of which is a module. The modules are comprehensive, systematic, and accompanied by a planned learning experience designed to help students master the learning objectives. This research is a preliminary stage of research on the digitalization of module products which was carried out using the Borg and Gall models. This study aims to describe the need to develop the digitalization of the Science Laboratory Management course module to strengthen the laboratory skills of prospective science educators. The method used is a literature study of the needs and other considerations related to the development of module products. The study results stated that digitizing the Laboratory Management module makes it easier for students to access materials anywhere and anytime. Learning becomes more focused and structured. The e-module was developed by considering the laboratory skill needs of prospective science educators. The selected laboratory skill indicators include mastery of practical tools, accuracy and accuracy of work, Occupational Safety and Health, and handling of chemicals.

Abstract

Critical thinking skills are crucial skills to be mastered by students in the 21st century. Critical thinking skills are also needed in the learning process, one of which is science learning. The Articulate Storyline learning media was developed to overcome students' need for critical thinking skills in science lessons. The research carried out is a development research (R&D) based on the Borg and Gall development model conducted by the Puslitjaknov Team. This study aims to analyze the level of validation of the Articulate Storyline learning media based on discovery learning in science learning in training the critical skills of junior high school students. The instrument involved in this study was an expert validation test questionnaire. The data presented in the study are qualitative and quantitative. Material experts who received validation results reached 88% in the "very valid" category, media experts got 100% in the very valid category, and science teachers scored 84% in the "valid" category. The discovery learning-based Articulate Storyline learning media that was developed has a good level of validation and can be used to train students' critical abilities.

Abstract

Personal and environmental hygiene must be considered to prevent the transmission of COVID-19. One of them is by washing hands with soap. Liquid soap is a skin cleanser made from soap-based ingredients and added surfactants, preservatives, foam stabilizers, fragrances, and dyes. The basic ingredients for soap can be natural, one of which is essential oil. Celery contains essential oils (alinin and allicin), flavonoids, protein, vitamin A, vitamin C, vitamin B, iron, calcium, sulfur, and phosphorus. Essential oil from celery has activity as an antifungal and is active against many bacteria, including Staphylococcus aureus. This study aims to determine the celery extract liquid hand soap has antibacterial activity against Staphylococcus aureus bacteria and the effective concentration of celery leaf extract liquid hand soap on the antibacterial activity of Staphylococcus aureus. The research method was laboratory experimental by testing the antibacterial activity of liquid hand soap formulations of celery leaf extract. The results of the organoleptic test were green in color, in viscous liquid form, and had a distinctive celery aroma. The pH test obtained a pH of 9.4 in the 5% formulation (FI), pH 9.5 in the 10% formulation (FII), and pH 9.3 in the 15% formulation (FIII). Antibacterial activity test FI, FII, FIII, negative control, and positive control resulted in a diameter of 17.1 mm inhibition zone; 23.2 mm; 17.4 mm; 0 mm, and 22.9 mm. The results of the one-way ANOVA test obtained a p-value <0.05, which indicated that H1 was accepted, i.e., liquid hand soap with celery leaf extract had antibacterial activity against Staphylococcus aureus. The Tukey test showed that the diameter of the FII inhibition zone (10% concentration) was close to that of the positive control inhibition zone. The most effective concentration is 10% (FII), with a very strong inhibition category.

Abstract

This study aims to determine the concentration of methanol solvent, the temperature, and the time of the shaker in the best extraction. It can produce the best antioxidant activity of the peel of the yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg) using the DPPH method. The maceration process is carried out using methanol solvents. The filtrate is concentrated with a rotary evaporator until a concentrated extract is obtained. Variations in methanol concentrations include 60, 80, and 100% (v/v) in methanol-water solvent mixtures. Shaker time variations in the extraction process include: 120, 140, and 160 minutes and shaker temperature variations in the extraction process include: 55, 65, and 75 °C. The results showed that the concentration of methanol solvent that can produce the best antioxidant activity from the peel of yellow passion fruit using the DPPH method is a concentration of 100% with an IC50 value of 31 ppm, followed by methanol solvents of 60% and 80% which produce IC50 values of 35 and 41 ppm, respectively. The optimum shaker time in the extraction process is 140 minutes, and the optimum shaker temperature in the extraction process is 65 oC. The conclusion is that using 100% methanol solvent, 140 minutes shaker time, and 65 oC shaker temperature can increase antioxidant activity in vitro using the DPPH method.

Abstract

The research aims to identify seawater quality conditions (physical and Chemical) in Gili Air Lombok and determine the water quality status using the pollution index method based on the Indonesian Minister of Environment Decree No. 115/2003. The method is descriptive research with quantitative and qualitative approaches. To identify water quality by comparing it with PP No. Water quality standard. 82/2001 concerning Water Quality Management and Water Pollution Control which includes physical parameters and chemical parameters. The water quality of Gili Air-sea based on the water pollution parameter test shows that the physical quality parameters still meet the required quality standards except for two chemical quality parameters. The pH of 6.3, and Phosphate has a value of 0.1 mg/l, which exceeds the quality standard seawater for marine tourism. Dissolved Phosphate in Gili Air waters comes from demineralization from the bottom of the waters in the form of coral. The movement of seawater accelerates demineralization. Phosphate in Gili Air waters also comes from seagrass productivity in these waters. However, the phosphate levels in the waters of Gili Air do not endanger the life of aquatic biota and do not interfere with the aesthetics of tourism. Meanwhile, based on the assessment of the status of water quality using the pollution index method. It was shown to be very lightly polluted with an IP value of 2.622.

Abstract

21st-century learning requires teachers to be more creative and innovative in determining learning that activates students. The classroom action research aims to improve learning outcomes of chemical change topics through practicum activities. The research was conducted in two cycles with an achievement indicator of 85% of students having mastered concepts above the minimum completeness. The subjects studied were students of grade ten high school SMAN 5 Mataram, 35 students. Learning outcome data were collected using test and non-test instruments. The test instrument collects cognitive data, while the non-test instrument or observation sheet collects affective and psychomotor data. Achievement indicators for cognitive if 85% of students have achieved minimum completeness criteria scores (≥74), while affective and psychomotor are said to be successful if 85% of students have achieved good categories. The results showed that in cycle 1, the cognitive results had not reached the target. Only 25 (78%) students achieved minimum completion, while affective and psychomotor had reached the target. In improving learning cycle 2, the number of students who achieved minimum completion increased to 33 (94%). In conclusion, learning chemical changes through practicum activities can improve learning outcomes.
