Abstract

Self-regulated learning is essential for students to be proactive in their learning, and creative thinking is crucial for overcoming challenges and generating innovative solutions. Project-Based Learning (PjBL) has been proposed as an effective method for teaching subjects such as renewable energy, allowing students to apply concepts in a real-world context. However, challenges persist in implementing PjBL, including student adaptation and lack of structured materials. This study aims to assess the impact of the PjBL model on students' self-regulated learning and creative thinking, identify factors that promote self-regulated learning, and understand barriers to developing creative thinking. Conducted at SMA Negeri 11 Sarolangun, this study involved two experimental classes and one control class. Using a mixed-method approach with a sequential explanatory design, this research employed a quasi-experimental method with a non-equivalent control group design. Data were collected using questionnaires, creative thinking tests, and interviews, and analyzed using parametric statistical tests and qualitative descriptive analysis. The results showed that PjBL had a significant positive impact on self-regulated learning and creative thinking, with a supportive learning environment being a key factor. The t-test results showed a significant effect on self-regulated learning (0.002) and creative thinking (0.04), both below the 0.05 threshold. Effect size analysis indicated a high impact on self-regulated learning and moderate impact on creative thinking variable.

Abstract

MA NU Banat Kudus has two educational programs: boarding and regular classes. These two programs differ, particularly in terms of independence; boarding school students live in school dormitories, which require them to be independent in many aspects of daily life. In addition, education in boarding schools is divided into two types, namely diniyah learning and regular learning, while regular students only have regular learning. Critical thinking is also an important aspect that must be considered. This study aims to analyze the differences in critical thinking skills and learning independence attitudes between boarding school and regular class students in physics learning at MA NU Banat Kudus. The method used in this study is a mixed methods with a triangulation design, combining a quantitative approach through tests and a qualitative approach through interviews. The study population consisted of grade XI students, divided into two groups: boarding and regular. Quantitative data analysis was carried out using the T test, while qualitative data were analyzed thematically. The results of the study showed that there was no significant difference in critical thinking between boarding school and regular students. Based on the t-test, a significant value of 0.67 was obtained, and the average results per aspect also showed no difference between boarding school and regular students. Meanwhile, the findings on student independence showed that boarding school students demonstrated better learning independence than regular students. This study recommends that schools develop more strategic planning for boarding programs to improve overall quality and implement active learning approaches, such as Problem-Based Learning, to enhance both critical thinking skills and learning independence among students in all types of schools.

Abstract

Indonesia has a diversity of medicinal plants that are used by the community to treat various diseases. Indonesian people often experience skin problems caused by fungi. The high number of cases of fungal diseases is due to the high air humidity in the tropics, thus supporting the growth of fungi that cause skin infections. This study examines the phytochemical content and antifungal activity of Baccaurea lanceolata (lempaung) plants. The parts of lempaung used as samples are the stem bark and fruit flesh. Samples were taken in Bioa Sengok Village, Rimbo Pengadang District, Lebong Regency. Antifungal testing was conducted at the Chemistry Education Laboratory and Microbiology Laboratory of Bengkulu University (UNIB) from January to June 2022. Antifungal activity testing uses the disc diffusion method by immersing the disc into the ethanol extract of lempaung. The test fungi used were C. albicans, M. furfur, and T. mentagrophytes. The results of phytochemical tests showed that the stem bark and fruit flesh samples of lempaung contained alkaloids, flavonoids, tannins, saponins, steroids, and terpenoids. The antifungal activity test results showed that the samples had inhibition against C. albicans, M. furfur, and T. mentagrophytes.

Abstract

Penelitian ini bertujuan untuk mengkaji densitas sebagai indikator degradasi minyak goreng akibat pemanasan berulang melalui pendekatan eksperimen berbasis Hukum Archimedes. Metode yang digunakan adalah eksperimen dengan pengukuran langsung terhadap tiga jenis minyak, yaitu minyak sawit, minyak kelapa, dan minyak jagung. Variabel independen berupa jenis minyak dan jumlah pemanasan (delapan siklus), sedangkan variabel dependen adalah densitas minyak. Pengukuran densitas dilakukan dengan membandingkan berat benda di udara dan di dalam minyak, dengan tiga kali pengulangan pada setiap perlakuan untuk meningkatkan reliabilitas data. Hasil penelitian menunjukkan bahwa densitas ketiga jenis minyak meningkat secara bertahap seiring bertambahnya jumlah pemanasan. Peningkatan densitas tertinggi terjadi pada minyak sawit, diikuti minyak kelapa, dan terendah pada minyak jagung. Temuan ini mengindikasikan bahwa pemanasan berulang menyebabkan degradasi kualitas minyak, yang tercermin dari peningkatan densitas. Dalam konteks parameter densitas, minyak jagung menunjukkan stabilitas yang relatif lebih baik terhadap pemanasan berulang dibandingkan minyak kelapa dan minyak sawit. Penelitian ini menegaskan bahwa densitas dapat digunakan sebagai indikator fisik yang sederhana dan aplikatif untuk menganalisis degradasi minyak goreng, meskipun interpretasinya masih terbatas pada aspek fisik dan memerlukan dukungan parameter kimia untuk evaluasi kualitas yang lebih komprehensif.

Abstract

Critical thinking is an essential competency in 21st-century physics learning because many physics concepts are abstract and require analytical as well as problem-solving abilities. The integration of Problem Based Learning (PBL) with PhET simulations is considered to support the development of these skills. This study aims to systematically analyse research trends on the implementation of PBL assisted by PhET simulations in improving senior high school students’ critical thinking skills in physics learning. The study employed a Systematic Literature Review (SLR) following PRISMA guidelines and was combined with bibliometric analysis using VOSviewer. Articles were identified through Google Scholar using Publish or Perish within the 2020–2026 publication period, producing 994 records at the identification stage. After the screening, eligibility, and inclusion processes, 64 articles met the inclusion criteria and were analysed. The findings indicate that publication trends rose during 2023–2024, the keywords Problem Based Learning, PhET simulation, critical thinking, and physics learning were strongly interconnected across four bibliometric clusters, and the most frequently studied physics topics were oscillation and waves, dynamic electricity, and motion with Newtonian concepts. Overall, the reviewed studies show a positive tendency of PBL assisted by PhET simulations in supporting students’ critical thinking skills.

Abstract

The aim of this research is to reduce household organic waste through the use of organic waste as a natural detector of formaldehyde content in food snacks. The organic waste used in this study was red garlic skins, dragon fruit skins and purple sweet potato skins. This research is an experimental research. The stages of the research started with the extraction of anthocyanins from the three organic wastes, direct detection of formalin and detection of food ingredients. The formalin concentrations tested were 0.5%, 1%, 2%, 5% and 25%. Detection ability can be seen from the color change between control and formalin treatment. Garlic skin produces a red extract, dragon fruit skin produces an orange extract, and purple sweet potato skin produces a deep red extract. Test results on 20 samples of food snacks around the campus using the three organic waste extracts proved that all samples contained formaldehyde in varying concentrations. The highest 50% formalin content was found in yellow noodles and meatballs. The conclusion is that purple beetle skin, dragonfruit skin, and red garlic skin can be used as natural detectors for formalin in campus snacks.

Abstract

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes

Abstract

This study aims to evaluate the use of chitosan as a substitute for formalin in making wet preparations of true bony fish (Osteichthyes) and to assess the feasibility of storing them as practicum media in the Vertebrate Zoology course. Osteichthyes body size varies from 1 cm to 6 meters. The main characteristic of Osteichthyes is the presence of a skeleton consisting of native bone and a hard calcium phosphate matrix. The skin is protected by various types of scales, including ganoid, cycloid, or stenoid scales. The research method used is Experimental Research Method with descriptive approach, which includes hedonic test and shelf life test (organoleptic) through panelist participation. Tilapia (Oreochromis niloticus) was used as the specimen in this experiment with variations in chitosan concentration of 0.50, 1.50, 2.50, and 3.50%. The study included evaluation of Osteichthyes wet preparations by considering aroma and odor, texture, color, as well as monitoring storage stability for one week. The results showed that the wet preparation using chitosan concentration of 3.5% gave satisfactory results for the observation of Osteichthyes structure. In addition, the storage evaluation showed that the quality of the preparations could be well maintained over a certain period. This indicates that chitosan can be an effective alternative in making Osteichthyes wet preparations for Zoology practicum

Abstract

Bioenergy is an alternative energy that utilizes various types of organic waste that can generate electricity. The purpose of this study was to determine the effect of fermentation time and coconut pulp concentration on the electrical characteristics of durian fruit skin, banana fruit skin, and cassava skin waste as an alternative energy source. The electrical characteristics observed were the voltage generated by fruit peel waste based on fermentation time and coconut pulp concentration. This research is a laboratory-based experimental research. The results of the study showed that: 1) the length of fermentation time affects the voltage generated by durian skin, banana skin, and cassava skin; 2) the fermentation time to produce the best voltage is the fourth day (96 hours); 3) the longer the fermentation time, the lower the voltage generated; 4) coconut pulp concentration affects the voltage generated by durian skin, banana skin, and cassava skin; 5) the ratio of 25% coconut pulp concentration and 75% raw material concentration becomes the ratio that produces the best voltage; 6) durian fruit peel waste has the highest voltage compared to banana fruit peel and cassava peel waste, both in terms of fermentation time or coconut pulp concentration. 7) cassava peel waste has a higher potential difference resistance than other skin waste
