Abstract

This study aims to extract and purify secondary metabolite compounds from Coffea arabica leaves using various separation techniques, such as maceration, column chromatography, thin layer chromatography (KLT), and preparatory KLT, and followed by flavonoid content analysis using UV-Vis spectrophotometry. The process begins with drying the arabica coffee leaves, then extraction is carried out using 96% ethanol for three days. After that, the solvent is evaporated with a rotary evaporator at 60°C to obtain a viscous extract. The extracts were further separated using column chromatography with a mixed solvent of n-hexane: ethyl acetate (3:1), resulting in 12 fractions that showed color differences, which was an indication of the diversity of the compounds in the extract. Advanced identification was carried out with KLT using methanol solvents: chloroform (9:1) at UV wavelengths of 254 nm and 366 nm, indicating the presence of compounds with medium to high polarity. Furthermore, the isolated compounds were further separated using the preparative KLT (KLTP) method. To determine the flavonoid content, UV-Vis spectrophotometry was performed at a wavelength of 431 nm, using quercetin as standard. The results of the analysis showed that Arabica coffee leaf extract had a yield of 7.35% and a total flavonoid content of 19.0605 mgQE/g. These findings show that arabica coffee leaves are a source of flavonoid compounds that have the potential for the development of herbal or phytopharmaceutical products. The flavonoid content found may provide health benefits, particularly in increasing antioxidant activity, which can be used in the treatment of oxidative stress-related diseases. The results of this study also open up opportunities for the development of plant-based products, especially Arabica coffee, in the pharmaceutical and cosmetic industries as an efficacious natural active ingredient.

Abstract

Penelitian ini bertujuan untuk membangun motivasi kewirausahaan masyarakat sebagai upaya strategis dalam meningkatkan perekonomian melalui pendidikan nonformal. Metode yang digunakan dalam penelitian ini adalah kajian literatur, yang menganalisis berbagai jurnal dan buku sebagai sumber utama data. Pengumpulan data dilakukan dengan menelaah sumber-sumber relevan yang mendukung analisis teoritis. Hasil penelitian menunjukkan bahwa motivasi kewirausahaan masyarakat dipengaruhi oleh minat, kesadaran akan peluang usaha, dan dukungan pendidikan nonformal. Selain itu, penelitian ini mengidentifikasi berbagai kendala yang dihadapi masyarakat dalam memulai dan mengembangkan usaha, seperti keterbatasan akses modal, keterampilan, dan jaringan pemasaran. Evaluasi terhadap peran pendidikan nonformal mengungkapkan pentingnya program-program pelatihan yang berbasis kebutuhan lokal untuk meningkatkan kemampuan kewirausahaan masyarakat secara berkelanjutan. Temuan ini diharapkan dapat menjadi landasan untuk pengembangan kebijakan dan program pendidikan nonformal yang lebih efektif dalam mendukung pemberdayaan ekonomi masyarakat.

Abstract

Permainan tradisional merupakan salah satu warisan budaya yang sarat akan nilai-nilai kearifan lokal. Permainan ini tidak hanya berfungsi sebagai hiburan, tetapi juga sebagai media pembelajaran yang mampu mengembangkan aspek sosial, emosional, dan fisik anak. Sayangnya, seiring perkembangan teknologi dan perubahan gaya hidup, permainan tradisional semakin terpinggirkan, terutama di kalangan anak-anak. Pengabdian ini bertujuan untuk melestarikan permainan tradisional sebagai bagian dari pendidikan karakter di tingkat sekolah dasar melalui integrasi dalam proses pembelajaran. Metode pengabdian ini menggunakan edukasi, praktik, dan dokumentasi. Hasil pengabdian menunjukkan bahwa saat bermain permainan tradisional, siswa dapat melepaskan emosinya dengan berteriak, tertawa, dan bergerak aktif. Gerakan dalam permainan tradisional, seperti berlari, melompat, berputar ternyata dapat membuat kepuasan, keseruan, dan membangkitkan rasa antusias memainkan permainan tradisional. Respons siswa menggambarkan bahwa permainan tradisional dapat menanamkan nilai luhur bangsa Indonesia. Selain itu, adanya respons antusias siswa dapat disimpulkan bahwa permainan tradisional juga menimbulkan kepuasan/keseruan dalam bermain, tidak kalah dengan permainan modern

Abstract

The coral reef ecosystem in Amahusu village has been damaged, resulting in reduced production of fisheries and other animal products. This damage is continuously caused by natural and unnatural factors, so that it can disrupt the economy of fishing communities who depend on marine products for their daily lives. The purpose of this activity is to equip the Maluku Protestant Church Youth Troops (AMGPM) Nusaniwe sub- district, the basics of coral conservation through coral reef restoration activities. Coral transplantation is a method of restoring the condition of coral reefs to restore and restore the natural ecosystem of coral reefs. The methods include: introduction of coral transplantation, preparation and process of coral transplantation. The introduction of coral biota is the most basic thing that the public must know in order to understand the potential and role of corals in the coral reef ecosystem. In addition, the community is gradually being taught how to use the correct transplant method, hopefully in the future they will be independent and able to do it themselves. Coral transplantation is one method of coral reef restoration in Amahusu Village. This presentation is a deep understanding of the community that with significant assistance they are expected to be independent in protecting coral reefs.
