Abstract

Sabun merupakan zat pembersih yang sangat penting dalam kehidupan sehari-hari, terutama untuk menghilangkan lemak dan berbagai jenis kotoran lainnya. Sebagai kebutuhan sekunder yang telah menjadi rutinitas masyarakat, sabun memiliki peran penting dalam menjaga kebersihan. Mengingat penggunaan sabun yang terus-menerus dapat mempengaruhi pengeluaran rumah tangga, kemampuan membuat sabun padat secara mandiri menjadi solusi yang ekonomis. Hal ini juga membuka peluang wirausaha bagi para siswa MAN 4 Kampar dalam industri pembuatan sabun. Pemanfaatan minyak jelantah sebagai bahan baku dapat meningkatkan kualitas sabun sekaligus memberikan nilai tambah pada limbah minyak goreng. Kegiatan pengabdian kepada masyarakat bagi siswa MAN 4 Kampar yang mana mitra  telah memiliki pengetahuan dan keterampilan  tentang bagaimana proses pembuatan sabun  padat dari minyak jelantah. Dan mitra dapat mengembangkan kewirausahaan berupa produk sabun padat dari minyak jelantah. Penggunaan minyak jelantah sebagai bahan baku sabun lebih hemat biaya dibandingkan penggunaan minyak nabati murni lainnya Usaha ini juga mendukung ekonomi berkelanjutan karena memanfaatkan limbah menjadi produk bernilai ekonomi tinggi dan ramah lingkungan Kata Kunci : sabun, safonifikasi, minyak jelantah

Abstract

The Baitul Quran located in Pekanbaru, is relatively new, which means it has a lot of vacant land. As a result, tree planting is necessary to beautify the environment. Similarly, Pekanbaru Sports High School also has vacant land that needs to be utilized. The methods employed sosialization, planting practise, and evaluation. Sosialization is conducted to enhance the partners' knowledge about the role of trees in mitigating the effects of climate change. Tree planting and maintenance practices are implemented to ensure that partners are capable of planting and caring for trees, contributing to the reduction of global warming. The results at Ponpes Baitul Quran and Pekanbaru Sports High School indicate an increase in student knowledge about climate change. Although students at both schools have a similar understanding of climate change, students at Pekanbaru Sports High School demonstrate a stronger grasp of climate change. In contrast, students at Ponpes Baitul Quran show a better understanding of the practical aspects of planting and maintaining trees. Tree planting on the vacant land at these schools creates microclimate. The survival of the trees ranges from 95% to 99%. The best growth in durian trees, followed by eucalyptus, with areca nut trees showing the lowest.

Abstract

Industri kosmetik mengalami pertumbuhan pesat, terutama di kalangan remaja, yang sering terpengaruh oleh media sosial. Namun, banyak produk skincare yang beredar mengandung klaim berlebihan atau bahan berbahaya. Program pengabdian ini bertujuan untuk memberikan edukasi sains kosmetik bagi siswa SMA Olahraga Pekanbaru melalui penyuluhan, pelatihan membaca label produk, serta praktik pembuatan skincare alami berbasis ilmu kimia. Metode pelaksanaan meliputi persiapan modul, sesi edukasi interaktif, praktik pembuatan produk kosmetik alami, dan evaluasi. Hasil kegiatan menunjukkan peningkatan pemahaman siswa sebesar 90% berdasarkan hasil pre-test dan post-test. Peserta juga menunjukkan antusiasme tinggi dan mampu menghasilkan produk alami seperti parfum herbal, masker wajah, dan body scrub. Kegiatan ini terbukti meningkatkan literasi sains, keterampilan praktis, serta potensi kewirausahaan siswa berbasis green chemistry.

Abstract

This study investigates the Brine Shrimp Lethality Test (BSLT) activity of leaf and gall fractions of Syzygium guineensis, a plant known for its traditional medicinal properties. The objective is to evaluate the cytotoxic potential of these fractions using BSLT, which is a reliable method for assessing toxicity. Leaf and gall samples were extracted using n-hexane, ethyl acetate, and ethanol-water solvents. The cytotoxicity was quantified by determining the LC50 values for each fraction. The results indicated that the leaf fractions exhibited LC50 values of 29.45 ppm (n-hexane), 28.33 ppm (ethyl acetate), and 30.57 ppm (ethanol-water). For the gall fractions, the LC50 values were 27.80 ppm (n-hexane), 26.61 ppm (ethyl acetate), and 24.95 ppm (ethanol-water). All fractions demonstrated significant cytotoxic activity, categorizing them as highly toxic. This study highlights the potential of both leaf and gall fractions of Syzygium guineensis as sources of cytotoxic agents, warranting further investigation for therapeutic applications.

Abstract

This study addresses the existing limitation in integrated waste valorization approaches by combining palm kernel shell–derived activated carbon production, waste cooking oil purification, and solid soap manufacturing within a UMKM-based circular economy model. Unlike previous studies that focus separately on adsorbent synthesis or oil purification, this research evaluates the adsorption performance quantitatively and links it directly to downstream soap quality. Activated carbon was synthesized via controlled pyrolysis (400 °C) followed by KOH activation (800 °C) and characterized using FTIR. The purification process reduced free fatty acid (FFA) content from 2.35 ± 0.02% to 0.43 ± 0.01%, corresponding to an adsorption efficiency of 81.7%. The adsorption capacity was calculated and statistical validation was performed in triplicate experiments. The resulting solid soap exhibited stable pH (8.89 ± 0.05) and satisfactory physical properties. These findings demonstrate the scientific and practical contribution of palm kernel shell activated carbon as a sustainable bioadsorbent supporting circular economy implementation at the UMKM scale.
