Abstract

Penelitian ini terfokus pada analisis Pedagogical Content Knowledge (PCK) calon guru kimia menggunakan CoRe (Content Representation) Framework dan strategi metakognitif pada mata kuliah Telaah Kurikulum Kimia. PCK merupakan representasi gabungan antara isi materi pelajaran dan pedagogik yang dimilik oleh guru sehingga siswa tertarik dan mudah untuk memahami suatu materi (Shulman, 1987). Oleh karena itu, CoRe framework dan strategi metakognitif pada penelitian ini digunakan untuk mengembangkan penguasaan konsep kimia dan cara menyampaikan konsep tersebut. Penelitian ini menggunakan pendekatan kualitatif, dengan studi interpretif kualitatif hingga menghasilkan profil PCK calon-calon guru kimia terkait dengan penguasaan konsep-konsep kimia. Data diperoleh dari rubrik PCK, MAIT (Metacogitive Awareness Inventory for Teachers), wawancara, observasi, nilai tes konsep, dan kertas refleksi. Hasil penelitian ini menunjukkan bahwa tingkat PCK calon-calon guru kimia tergolong tinggi. Terlihat bahwa Content Knowledge (CK) yang mereka miliki sedikit lebih tinggi daripada Pedagogical Knowledge (PK). Hasil MAIT (Metacogitive Awareness Inventory for Teachers) juga menunjukkan bahwa calon-calon guru tersebut memiliki kesadaran metakognitif yang sangat tinggi sehingga mereka mengetahui kelemahan dan kekuatannya sendiri dalam mengajar. Kata kunci: Pedagogical Content Knowledge, Content Representation, Strategi Metakognitif, Telaah Kurikulum Kimia

Abstract

This study aims to determine the effect of the application of cooperative learning models type Group Investigation based ICT on students' communication skills. This research was conducted with quantitative methods. The sampling technique uses purposive sampling. Learning was carried out in one experimental class and one control class by applying cooperative learning models type GI based ICT and non ICT. The research instrument uses statement questions that have been declared valid and reliable. The results of hypothesis testing of two independent samples obtained t stat (2,897)> t table (1,667), so it can be concluded that there is a positive influence on the application of cooperative learning type Group Investigation based ICT on students’ communication skills. Further analysis on each indicator of communication skills, it can be seen that indicators identifying problems, gathering information, and drawing conclusions have a significant influence on the results of the experimental class and the control class. While indicators write summaries and use good grammar and spelling, there is no significant influence between the experimental class and the control class.

Abstract

Waste cooking oil has been repurposed in the preparation of liquid hand soap, enriched with Aloe vera extract as an antibacterial agent. To ensure the safety and efficacy of the product in bacterial inhibition, comprehensive testing of physical quality and antibacterial activity has been undertaken on the produced liquid soap. The test results affirm that the soap product complies with the Indonesian National Standard for free alkali content, acidity level (pH), foam height, foam stability, and water content. Notably, the soap exhibits a free alkali content of 0.01873%, a pH of 10, a foam height of 65 mm, and a foam stability value of 84.61%. The water content in the soap is measured at 40%. These results collectively position the soap within the criteria for high-quality soap. In the antibacterial effectiveness test against Staphylococcus aureus and Escherichia coli bacteria, the addition of Aloe vera has markedly expanded the inhibitory zone, demonstrating a significant enhancement in antibacterial activity. In light of the above, this study aims to address environmental pollution and health risks associated with improper disposal of waste cooking oil. Moreover, the addition of antibacterial Aloe vera presents an economically valuable solution by repurposing waste cooking oil into a useful product.

Abstract

AuPt Bimetal has been successfully synthesized by electrodeposition method with potentiostat technique. By varying the concentration of Au ions in the solution they are able to control the morphology and composition of the synthesized sample. The morphology obtained from the AuPt synthesis is cauliflower. The effect of Au ion concentration in solution on the catalytic performance of AuPt, the greater the Au concentration, the greater the current density in the electrooxidation reaction. In addition, the concentration of Au ions in the solution affects the results of the deposition of Au and Pt elements. In the study of AuPt nanocatalysts with a 0.4 mM Au ion concentration in an electrolyte solution, it was shown to have good catalytic activity in the ethanol electrooxidation reaction, with the resulting current densities and If/Ib of 10.1 mA/cm2 and 43.53 mA/cm2, respectively. This is an implication of many Au compositions which are known to have the ability to absorb and oxidize CO to encourage an increase in current density and increase its catalytic activity.

Abstract

Abstract The earthquake that struck the Cianjur region had an impact on the economic resources and income of the community, including those in the Sawah Gede neighborhood. This natural disaster affected the crucial sectors of the community's economic activities, indirectly leading to a decline in the economic performance of the area. However, when viewed from a positive perspective, this natural disaster actually has the potential to trigger new economic growth in the region. The emergence of new economic growth can be facilitated, in part, by the establishment of small home-based industries. One option that the community can consider is the production of soap using used cooking oil as a raw material. This potential is substantial, given the high consumption of cooking oil by the community, which is directly proportional to the increase in the amount of used cooking oil waste generated. This business opportunity not only contributes to the growth of the community's economy but also educates the public about environmental conservation. This Community Service Program (PKM-KKN) is implemented as an effort to empower the community's economy through the production of liquid hand soap. This involves various stages, including the manufacturing process, product packaging, and product promotion. Abstrak Gempa bumi yang melanda wilayah Cianjur berdampak pada sumber ekonomi atau pendapatan masyarakat, Salah satunya masyarakat di kelurahan Sawah Gede. Bencana alam ini berdampak pada sektor penting kegiatan ekonomi masyarakat, yang secara tidak langsung berimplikasi pada penurunan kinerja perekonomian wilayah tersebut. Namun, jika dilihat dari sisi positifnya, bencana alam justru berpeluang dapat memicu pertumbuhan ekonomi yang baru di wilayah tersebut. Pertumbuhan ekonomi baru dapat dibentuk salah satunya dengan menciptakan industri kecil rumahan. Salah satu opsi yang dapat dipilih masyarakat adalah industri pembuatan sabun berbahan baku minyak jelantah. Potensi ini cukup besar mengingat konsumsi minyak goreng masyarakat yang tinggi dan berbanding lurus dengan peningkatan jumlah limbah minyak goreng yang dihasilkan. Peluang usaha tersebut tidak hanya berpengaruh pada meningkatnya pertumbuhan ekonomi masyarakat tetapi juga mengedukasi masyarakat untuk turut menjaga lingkungan. Kegiatan PKM-KKN ini dilaksanakan sebagai upaya dalam pemberdayaan ekonomi masyarakat melalui pembuatan sabun cair cuci tangan, kemudian pengemasan produk hingga promosi produk.
