Abstract

Kegiatan pengabdian pada masyarakat (PPM) bertujuan untuk: (1) meningkatkan pengetahuan masyarakat Seyegan tentang bahan dan manfaat sabun scrub alami dari ampas kopi, (2) meningkatkan ketrampilan masyarakat dalam pemanfaatan teknologi tepat guna pembuatan sabun scrub alami dari ampas kopi, dan (3) memotivasi minat wirausaha masyarakat Seyegan. Kegiatan PPM ini bersifat pelatihan dan dilaksanakan dengan metode ceramah, diskusi dan praktik. Melalui kegiatan tersebut, peserta telah mendapat materi tentang: (1) pembuatan sabun scrub alami dari ampas kopi, (2) kandungan dan manfaat kopi untuk kesehatan kulit, (3) sabun yang aman untuk kesehatan kulit, (4) peluang wirausaha sabun kopi, dan (5) pewarna dan pewangi yang bersifat skin grade. Peserta yang telah mengikuti pelatihan ini berjumlah 11 orang yang merupakan masyarakat di daerah Padukuhan Kamal Wetan, Mangsel VII, Margomulyo, Seyegan. Evaluasi kegiatan PPM dilakukan dalam 2 tahapan, yaitu evaluasi proses melalui observasi selama kegiatan PPM dan evaluasi hasil melalui produk sabun yang dihasilkan serta isian angket kegiatan PPM. Melalui kegiatan ini, dapat disimpulkan bahwa peserta pelatihan telah memperoleh (1) manfaat tentang bahan dan sabun alami dari ampas kopi, (2) pengetahuan dan keterampilan dalam pemanfaatan teknologi tepat guna pembuatan sabun scrub alami dari ampas kopi, namun motivasi dan minat wirausaha peserta pelatihan untuk membuat sabun scrub ampas kopi masih perlu untuk ditingkatkan.

Abstract

Pluchea indica (L.) leaves, both in the form of extracts and silver nanoparticles, are known to exhibit antibacterial activity, but they have not been widely utilized in the health sector, especially in dermatology. This study aims to determine the quality test and antibacterial evaluation of natural soap formulated with methanol extract and nanoparticles of Pluchea indica (L.) leaves against Propionibacterium acnes. The synthesis of silver nanoparticles (AgNPs) was conducted using the reduction method, with AgNO3 as a precursor and methanol extract of Pluchea indica (L.) leaves serving as a reducing agent or bioreductor. Natural soap was produced through the cold process method, with a curing period of 3 to 4 weeks. Natural soap, derived from herbal ingredients, was made by combining NaOH, essential oils, and additives such as methanol extract and silver nanoparticles from Pluchea indica (L.) leaves. Quality tests were performed to assess moisture content (MC), fatty acid content, and pH levels. Antibacterial activity was assessed utilizing the well-diffusion method, with various sample concentrations ranging from 1.0 g/mL to 0.0625 g/mL. The quality test results for all soap samples met the Indonesian National Standard (SNI) requirements for acidity, free fatty acids, and moisture content. The bar soap without additives exhibited antibacterial activity, with a maximum inhibition zone of 14.26 mm (at 0.25 g/mL) after 15 hours. Natural soap with methanol extract of Pluchea indica (L.) leaf demonstrated an inhibition zone of 11.49 mm (at 0.0625 g/mL) after 15 hours, while nanoparticle soap exhibited an inhibition zone of 12.77 mm (at 0.25 g/mL) after 12 hours. In summary, all soap samples showed antibacterial activity, indicating the potential of Pluchea indica (L.) leaves as effective antibacterial agents.

Abstract

Chemistry is one of the difficult subjects at all levels of education, this is what makes it difficult for students to solve problems so that student learning outcomes decrease. The things that cause chemistry learning problems are influenced by monotonous learning process activities, the application of less innovative learning models and methods that have a negative impact on students' ability to understand chemical concepts. This research aims to find out the implementation of problem solving in chemistry learning. This research method uses a systematic literature review (SLR) by analyzing previous research using the Google Scholar and Scopus databases in the last 10 years, namely 2014-2022. The 14 articles reviewed were obtained after going through the scanning process according to the inclusion criteria. The results of this study indicate that in chemistry learning it is necessary to improve problem solving in chemistry learning.

Abstract

This study analyzes green chemistry research trends in chemistry education. This study used a quantitative bibliometric approach. The number of publications analyzed is 104 publication documents from 2019 “ 2024. This research collects, processes, and filters information in Scopus journals and articles. Metadata results show that the distribution of publication frequency peaked in 2019, with 26 documents identified. The green chemistry research area is dominated by chemistry research (31.3%). The country with the most documents and the most productive in publishing green chemistry is the United States, with 30 papers identified. At the same time, Indonesia is ranked fifth as the most productive country in publishing green chemistry, with 10 documents identified. Canada ranked second with 17 papers, and Germany ranked third with 15 documents. The institutions that contributed the most came from Germany: the University of Bremen, with 11 papers 10.58%, and the University of Toronto with 8 documents (7.69%). The authors with the most citations are Chen Tse-Lun et al., with 245 citations. Meanwhile, when viewed from the number of documents published by the author, Eilks I. has 11 papers with a contribution of 4.91%. There are 5 clusters with the most popping keywords: green chemistry, human, and chemical reaction. Research and publications on this topic have been sparse in the past five years. Surveys and analyses of green chemistry literature are essential because tracking research trends in green chemistry in chemistry education is vital to directing the future.
