Abstract

Kampung Laut merupakan salah satu Kelurahan yang berada di Kecamatan Kuala Jambi Tanjung Jabung Timur yang memiliki sumber daya alam yang tidak termanfaatkan limbahnya yaitu serabut cangkang buah dari tanaman nipah. Selama ini masyarakat Kampung Laut hanya memanfaatkan buah nipah sebagai produk olahan pangan seperti dodol, tetapi limbah dari serabut cangkang buah nipah terbuang dan tidak dimanfaatkan. Cangkang buah nipah yang mengandung selulosa tinggi sehingga jika diolah menjadi arang aktif berubah menjadi karbon yang memiliki efektifitas kemampuan penyerapan kotoran, racun dan minyak pada kulit. Dengan melihat potensi ini maka muncul ide untuk mengolah arang aktif cangkang buah nipah menjadi produk kosmetik masker gel peel off. Tujuan kegiatan pengabdian kepada masyarakat ini adalah mampu memberi nilai jual tanaman nipah khususnya cangkang buah nipah yang terbuang, meningkatkan pengetahuan masyarakat mengenai cara pembuatan masker gel peel off, dan memaksimalkan sumber daya manusia di kelurahan Kampung Laut. Metode yang digunakan dalam pelatihan ini, yaitu penyuluhan tentang tanaman nipah, pembuatan masker gel peel off, dan aplikasi masker gel peel off pada wajah. Kegiatan ini menghasilkan produk kosmetik masker gel peel off berbahan dasar natural dari arang aktif cangkang buah nipah. Manfaat dari PPM ini yang dapat meningkatkan nilai jual dari tanaman nipah , serta meningkatkan kreativitas sumber daya manusia di Kelurahan Kampung Laut, Kecamatan Kuala Jambi, Kabupaten Tanjung Jabung Timur.

Abstract

This study presents the development and application of an innovative 3-in-1 nanotechnology pyrolysis reactor designed to simultaneously produce liquid smoke, activated carbon, and limestone from locally sourced raw materials in Jambi Province, Indonesia. The multifunctional reactor combines three production processes, which are traditionally performed separately, into a single, efficient unit, addressing both economic and environmental challenges. Coal serves as the primary heat source and material for activated carbon, whereas shell waste is calcined to produce limestone. The reactor operates at temperatures exceeding 550°C to ensure optimal conversion, with a glass wool insulator replacing clay to enhance thermal efficiency. The liquid smoke undergoes further distillation to achieve purification, while residual activated carbon is chemically activated with H₃PO₄ to enhance its adsorption capacity. The experimental results demonstrate that this reactor can produce high-quality products with minimal resource wastage. This 3-in-1 pyrolysis reactor represents a sustainable, cost-effective solution for resource-limited settings, with broad potential for application in waste-to-product conversion, environmental remediation, and rural development.

Abstract

Remazol Yellow is a dye that contains an basic amino group and a benzene core, so it is difficult to be naturally degraded by microorganisms and causes environmental pollution. One solution to reduce the dye waste polluted in waters can be done by adsorption method using pineapple peel cellulose as adsorbent. Before turning into pineapple peel cellulose, the NaOH delignification process and H2SO4 hydrolysis were carried out first. The adsorption process for rhodamine B dye was carried out on 2 parameters, namely pH, contact time and determination of the adsorption system using the Langmuir and Freundlich equations at various concentrations of 5, 10, 15, 20, 25, 50, 75 and 100 ppm. Testing the effect of pH on the adsorption of Remazol Yellow was carried out with variations in pH namely 2, 3, 4, 5, 6, 7 and 8. . The results showed the optimum conditions at pH 2, contact time of 30 minutes and the Langmuir isotherm adsorption system with an adsorption capacity of 19.888 mg/g

Abstract

physiological or metabolic processes that can cause cancer in humans. Adsorption is one of the method that is quite effective for removing Cr(VI) in waters because this method uses low cost with good efficiency. Sugar palm fruit peel waste can be used as an adsorbent because it contains active compounds such as carbohydrates, proteins, fats that can play a role in the absorption of metal ions. This sugar palm peel waste will be immobilized using a Ca-alginate medium to increase the absorption of mechanical forces in the adsorption process. The sugar palm fruit peel was activated using 4% NaOH, which was then immobilized by Ca-alginate. The adsorbent was tested to determine its functional group using FTIR and using SEM EDX to see the surface morphology and the elements present in the adsorbent. The results showed that the optimum absorption of metal ions Cr(VI) using Ca-alginate immobilized palm peel as adsorbent at optimum pH 2 with an efficiency of 63% and adsorption capacity of 0.35396 mg/g, the optimum contact time was 75 minutes with an efficiency of 73, 83% and adsorption capacity of 0.41314 mg/g and the optimum concentration at 150 ppm with adsorption capacity of 13.15185 mg/g
