Abstract

In this modern era, noise has become an increasingly common and significant problem in everyday life, thus requiring the use of sound absorbers to address this noise issue. This research created a sound absorber using coconut husk waste through the impedance tube method. Sound absorbers can be made by utilizing readily available waste materials, such as coconut husk waste. The effectiveness value of the coconut fiber absorption coefficient was tested using the impedance tube. The research method employed was the impedance tube method, with variations ranging from level 1 to level 5 and frequencies of 200 Hz, 400 Hz, 600 Hz, and 800 Hz. The impedance tube lengths used in this study were 50 cm and 100 cm. The highest absorption result at a tube length of 50 cm was found at level 1 with a frequency of 200 Hz. At a tube length of 100 cm, the highest absorption value was observed at level 2 with a frequency of 600 Hz. Based on this research, it was concluded that coconut husk can minimize noise and serve as an effective sound absorber.

Abstract

The increasing demand for paper has significantly impacted the environment due to the heavy reliance on wood as a primary raw material. This study investigates the feasibility of using durian (Durio zibethinus) peels and corn (Zea mays) stalks as alternative raw materials for paper production, focusing on their physical characteristics. The paper pulp was prepared using the soda pulping method with NaOH. Various ratios of durian peels and corn stalks were mixed: 1:0 (A), 0:1 (B), 1:1 (C), 2:1 (D), and 1:2 (E). Results indicated that type D produced the thickest paper, while type A produced the thinnest. The highest grammage was observed in type E, and the lowest in type D. Type C showed the highest absorbency. The tensile and tear indexes were highest in type D and lowest in type C. Type A had the highest mass density, whereas type D had the lowest. The findings suggest that a combination of durian peel and corn stalks exhibits diverse physical properties, indicating their potential use as an alternative to conventional wood-based paper. This approach could reduce the dependency on wood and contribute to environmental conservation.

Abstract

The Adiwiyata program seeks to cultivate knowledge and awareness of ecological conservation among students. This study compared environmental literacy between ninth-grade students in Adiwiyata and non-Adiwiyata schools in Balikpapan City, Indonesia. Utilizing a questionnaire adapted from the Middle Schools Environmental Literacy Survey, data was collected across five domains: knowledge, attitudes, participation, awareness, and skills. An independent sample t-test gauged mean variations in both school types. Results indicated that Adiwiyata students achieved good environmental literacy, while non-Adiwiyata students reached an acceptable level. Noteworthy differences were observed across all domains, with the knowledge domain being particularly distinct. Strengthening environmental literacy requires schools to implement programs reinforcing environmental values. This study underscores the importance of educational initiatives fostering a sense of responsibility for the environment among students in both Adiwiyata and non-Adiwiyata schools.

Abstract

Research on place attachment (an individual's emotional bond with their environment) and pro-environmental behavior (attitudes and actions to protect the environment) is important to understand how an individual's emotional bond with their environment can influence pro-environmental behavior, especially for students. This study aims to evaluate the level of place attachment and pro-environmental behavior among junior high school students in Samarinda and examine the correlation between the two variables. This study used a quantitative approach with survey techniques. The research sample consisted of 378 junior high school students in Samarinda who were randomly selected. Data were collected using questionnaires. The results showed that the level of place attachment of junior high school students in Samarinda was 3.75 which was categorized as moderate, while the level of pro-environmental behavior was 3.58 which was also categorized as moderate. A positive but very low correlation existed between place attachment and pro-environmental behavior. This study shows the importance of considering place attachment factors in developing approaches to improve pro-environmental behavior among secondary school students.

Abstract

Pre-service teachers play an important role in teaching and influencing future learners. One of the important skills that prospective teachers must have is mathematical ability, so information about pre-service teachers' learning tool preferences in understanding mathematical concepts is crucial. This study aims to identify pre-service teachers' learning tool preferences for understanding mathematical concepts. This study used mixed methods, quantitative and qualitative. Data collection was carried out by distributing questionnaires to 129 prospective teachers from mathematics and science education study programs, as well as elementary school teacher education at Mulawarman University. Quantitative questions used Likert scale-type questions, and qualitative used free-response questions to get an in-depth analysis. The results of this study showed a very weak correlation between learning aid preferences and the understanding of basic math concepts, but it increased considerably when linked to advanced math concepts. In addition, there is a difference in preference between male and female pre-service teachers, where males are more likely to favor tools such as AI or ChatGPT, while females prefer learning videos. This study is expected to provide valuable information for policymakers to provide facilities that support the learning needs of pre-service teachers.

Abstract

Kemampuan berpikir kritis penting dalam menghadapi tantangan Abad 21 dan perlu dilatihkan kepada peserta didik. Model Problem Based Learning (PBL) berpotensi memfasilitasi pengembangan keterampilan ini karena menuntut peserta didik untuk belajar secara langsung dan memecahkan masalah, sehingga meningkatkan kemampuan berpikir kritis. Penelitian ini bertujuan untuk mengetahui pengaruh model PBL terhadap kemampuan berpikir kritis peserta didik pada materi usaha, energi, dan pesawat sederhana. Jenis penelitian ini adalah pre-experimental design dengan desain one group pretest-posttest. Sampel penelitian adalah 38 siswa kelas VIII yang dipilih secara purposive. Data dikumpulkan melalui tes essay dengan indikator berpikir kritis Facione: penafsiran, analisis, kesimpulan, evaluasi, dan penjelasan. Hasil menunjukkan peningkatan berpikir kritis dengan N-Gain 0,74 dan p-value 0,000 < 0,05. Model PBL efektif sebagai alternatif untuk mengembangkan kemampuan berpikir kritis di sekolah.

Abstract

This research investigates gender disparities in Indonesia's National Science Olympiad (OSN) Achievements. This research uses mix research, quantitative and qualitative. Data for quantitative analysis we get from secondary data, national achievement center website. Qualitative data we get from questionnaire with free response question, and distributed to students, teachers, and special teachers. For quantitative research we use Mann-Whitney U test whereas qualitative research we use content analysis. This research found that males are dominance to females in almost all subjects of National Science Olympiad Achievements significantly. Social stereotypes about boys using more logic and reasoning while females use more emotion, influence female self-perception and performance in understanding math and science. In terms of biology, it also shows that there are concerns of female participants when participating in OSN, they are in the menstrual period. They felt that when they were menstruating, not only did they feel abdominal pain, they also felt unstable emotions. This reduces the performance of female students when participating in the OSN Competition. The stereotype of females taking care of more household tasks or problems, causing less support from parents to female children than that given to male children. The lack of freedom gained by the female students reduces their study time for OSN preparation
