Abstract

While collaborative problem-based learning (PBL), particularly in Western nations, has been researched and shown to be beneficial in enhancing students' metacognitive skills, it is still sparingly used in Asian nations like Indonesia. This study's goal was to learn more about the potential benefits of cooperative PBL on students' metacognitive skills. The systematic literature review (SLR) research design was used for this study, and the requirements were full text, journal articles, open access, accredited national and international publications between 2010 and 2020, and articles on the role of collaborative PBL in chemistry students' metacognitive development. The findings of the SLR used in this study show that PBL enhances students' metacognitive skills, particularly in chemistry students. The majority of research, however, continues to employ unreliable, nonstandard methods. Therefore, it is believed that this research may be used as supplemental data to acquire in-depth PBL findings.

Abstract

Kemunculan bakteri resisten antibiotik menjadi masalah serius di seluruh dunia. Upaya penanggulangan bakteri resisten antibiotik terus dilakukan, salah satunya dengan penggunaan material berukuran nano. Zink oksida (ZnO) merupakan salah satu partikel yang telah terbukti dapat menghambat pertumbuhan bakteri gram negatif dan gram positif. Dalam mencegah terjadinya aglomerasi pada sintesis ZnO berukuran nanometer dapat ditambahkan capping agent alami berupa senyawa metabolit sekunder pada ekstrak kulit pisang raja nangka. Adapun langkah yang dilakukan adalah: 1) ekstraksi metabolit sekunder kulit pisang raja nangka, 2) uji fitokimia, 3) penentuan kadar total flavonoid dan polifenol, 4) sintesis ZnO dengan capping agent alami ekstrak kulit pisang raja nangka, 5) karakterisasi ZnO, dan 6) uji aktivitas antibakteri ZnO. Hasil analisis kualitatif melalui uji fitokimia serta analisis kuantitatif melalui penentuan kadar total polifenol dan flavonoid menunjukkan bahwa ekstrak kulit pisang raja nangka etanol (96%)-air 2:1 (v/v) memiliki kadar metabolit sekunder yang lebih tinggi dibandingkan ekstrak kulit pisang raja nangka etanol (96%)-air 1:1 (v/v). Partikel ZnO berhasil disintesis menggunakan capping agent alami ekstrak kulit pisang raja nangka. Kadar metabolit sekunder yang berbeda pada masing-masing ekstrak mempengaruhi ukuran, morfologi, dan aktivitas antibakteri ZnO hasil sintesis.

Abstract

It is crucial that the concepts of buffer solutions must be properly understood by students. It is due to the fact that buffer solutions are closely related to daily life, for example in blood, drugs, and others. The results of research and interviews show that students' understanding and student learning outcomes about the buffer solution material is still low. A student-centered learning process is needed so that it can make the learning process more fun and improve students’ learning outcomes. A meaningful student-centered learning is needed for the Learning Cycle (LC) learning model. However, the group discussion on the 5E LC learning model was less patterned, so it was combined with a patterned cooperative learning model that is Think-Pair-Share (TPS). This study aims to see the implementation of the learning process from the classroom with 5E LC -TPS and 5E LC learning models, and the influence of the 5E LC-TPS on cognitive learning outcomes from the eleventh grade students of Sidoarjo on buffer solution material. The design of the study used in this study is a quasi-experimental design with post-test-only-control group design. The research finding showed that: (1) the implementation of the learning process of the two categorized classes was done very well that is 98.3 percent in the experimental class and 95.4 percent in the control class, (2) there is the influence of the 5E LC learning model combined by TPS on the cognitive learning outcomes of class students as indicated by the significant average differences of the two classes. The average value of cognitive learning outcomes of experimental class students is higher than the control class which is equal to 85.43 and the control class is 81.62. From the results of these studies it can be concluded that there is the influence of the 5E LC-TPS learning model on improving students' cognitive learning outcomes. Konsep-konsep larutan penyangga perlu dipahami siswa karena larutan penyangga erat kaitannya dengan kehidupan sehari-hari, misalnya penyangga karbonat dalam darah, obat-obatan, dan lain-lain. Hasil penelitian dan wawancara menunjukkan bahwa pemahaman siswa dan hasil belajar siswa tentang materi larutan penyangga masih rendah. Diperlukan suatu proses pembelajaran yang berpusat pada siswa sehingga dapat menjadikan proses pembelajaran lebih bermakana dan meningkatkan hasil belajar siswa. Salah satu pembelajaran bermakna yang berpusat pada siswa adalah model pembelajaran Learning Cycle (LC). Namun, diskusi kelompok pada model pembelajaran LC 5E kurang berpola, sehingga dipadukan dengan model pembelajaran kooperatif yang berpola yaitu Think Pair Share (TPS). Penelitian ini bertujuan untuk melihat keterlaksanaan proses pembelajaran dari kelas dengan model pembelajaran LC 5E-TPS dan LC 5E serta pengaruh model pembelajaran LC 5E -TPS terhadap hasil belajar kognitif siswa kelas XI SMA Negeri Sidoarjo pada materi larutan penyangga. Rancangan Penelitian yang digunakan dalam penelitian ini adalah rancangan eksperimental semu dengan post-test-only-control group design. Hasil penelitian menunjukkan bahwa: (1) keterlaksanaan proses pembelajaran kedua kelas terkategori terlaksana dengan sangat baik, yaitu 92,11 persen pada kelas eksperimen dan 90,78 persen pada kelas kontrol. (2) ada pengaruh model pembelajaran LC 5E yang dipadu TPS terhadap hasil belajar kognitif siswa kelas yang ditunjukkan oleh perbedaan rata-rata yang signifikan dari kedua kelas. Nilai rata-rata hasil belajar kognitif siswa kelas eksperimen lebih tinggi dari pada kelas kontrol yaitu sebesar 85,43 dan kelas kontrol sebesar 81,62. Dari hasil penelitian tersebut dapat disimpulkan bahwa ada pengaruh model pembelajaran LC 5E-TPS terhadap peningkatan hasil belajar kognitif siswa.

Abstract

In this era, most technology requires electronic equipment. The performance of electronic equipment may be affected by energy storage components like a supercapacitor, so the development of supercapacitor electrode materials using green chemical methods needs to be pursued. Material with a good specific capacitance is MnO2. Most of the MnO2 synthesis methods are not based on green chemistry, so there is an alternative method. One of them is by utilizing the waste from tangerine peels. This study aimed to synthesize MnO2 through dehydroxylation of tangerine peel essential oil. The steps for conducting this research consisted of isolation of tangerine peel essential oil, analysis of the constituent components of tangerine peel essential oil, synthesis of MnO2 through dehydroxylation of essential oils tangerine peel, and MnO2 characterization. XRD results showed that MnO2 synthesized at pH 11 had the highest percentage of α-MnO2 (97%). This is evidenced by the presence of α-MnO2 diffractogram according to the ICSD No.20227. The SEM results showed that MnO2 had a spherical morphology with a particle diameter of 39.51 nm. α-MnO2 has a larger tunnel structure compared to β- and γ-MnO2, making the charge-discharge process easier so that α-MnO2 has the potential as a supercapacitor electrode material.

Abstract

A green chemistry-based ZnO nanoparticle synthesis method based on plant extracts has been developed. Raja nangka banana peel is one of them. The extraction time is one of the elements that influences the amounts of secondary metabolites. The longer the extraction time, the more secondary metabolites are obtained. If the optimal time is exceeded, the secondary metabolite compounds will decrease. The purpose of this research was to determine the optimal time to extract secondary metabolites from the raja nangka banana peel and to know the effect of extraction time on the characteristics of ZnO nanoparticles, which include morphology, size, and antibacterial activity against Staphylococcus epidermidis. The steps of this research: maceration, phytochemical tests and total levels tests, synthesis of ZnO nanoparticles, characterization, and antibacterial activity test against Staphylococcus epidermidis. Maceration for 24 hours is the best time for extracting secondary metabolites from raja nangka banana peels. The SEM test results show that the morphology of the three samples had agglomeration. The ZnO nanoparticles with 24-hour raja nangka banana peel extract had a smaller size of 295.2 nm and were spherical. Inhibition zone diameter from ZnO nanoparticles with 24-hour raja nangka banana peel extract has a larger area of 5.65 mm.

Abstract

This study aims to compare the impact of the Dual Situated Learning Model (DSLM) and conventional instructions in improving High School Students’ understanding of chemical equilibrium concepts and the prevention of possible misconceptions. The study utilized a quasi-pretest-posttest control and experimental group design with two classes of XI SMAN as the research sample (N=60 students). Pre-posttests consisting of 12 two-tier questions (r = 0.691) used to assess the learners’ understanding of the chemical equilibrium. The results showed a significant difference in favor of the learners who taught using the DSLM model in comparison to those in the conventional approaches (Fount = 4.149; p = 0.003). Students in the experimental class had a better understanding and fewer misconceptions about the concept of chemical equilibrium. Implications for science educators suggest that learning that is designed by considering students' misconceptions or preconceptions and anticipating them through appropriate learning steps will have a positive influence on the learners’ conceptual understanding.
