Abstract

Referring to data from the Directorate General of Plantations of the Ministry of Agriculture throughout 2019, the area of oil palm plantations in Indonesia is estimated at around 14.68 million hectares, with total production reaching 51.8 million tons per year or the largest in the world. In 1 ton of palm oil produces 6.5% shell waste or 65 kg. Nanocarbons with their unique properties are now widely used in various applications such as batteries, supercapacitors, sensors and so on. Utilization of palm fruit shell waste as a nanocarbon material with a micropore structure, large surface area and high pore volume is the goal of this research.

Abstract

In one coal combustion process, about 80% of fly ash is produced and the rest is bottom ash, which is around 20%. The main components of coal fly ash originating from power plants are silica (SiO2), alumina (Al2O3), and iron oxide (Fe2O3), the rest are carbon, calcium, magnesium, and sulfur. Silica is one of the most dominant components of fly ash. Hydrogels obtained without fillers still have a Swelling capacity that is not maximized, it is necessary to process hydrogels with high absorption capabilities. One of the methods used to increase the absorption of hydrogels is to add silica as a voice filler. This study aims to determine the effect of 10, 20, 30, and 40% silica content from coal fly ash as a filler for bacterial cellulose-based hydrogels. Silica was obtained by extracting sodium silicate solution from fly ash followed by the manufacture of silica gel using 3N H2SO4. The resulting silica gel is added to the hydrogel manufacturing process. Hydrogel with silica as a filler which produces water absorption, FTIR, and SEM. The test results show that the silica content of 20% has the highest water absorption capacity of 1290%. With the concentration used, silica precipitation will produce a sharper silica peak in the FTIR results. SEM analysis with the addition of silica with bacterial cellulose produces pores on the HSB surface which can absorb air more quickly. The pores on the surface of the HSB affect the water absorption capacity (hydrophilicity) to increase. The addition of silica precipitated from fly ash waste as a filler in Bacterial Cellulose Hydrogel (HSB) was able to increase the Swelling capacity of HSB

Abstract

Forum Kewirausahaan Pemuda (FKP) merupakan komunitas wirausaha Nasional yang menyebar disetiap provinsi di Indonesia, yang annggotanya memiliki usaha berusia 17-45 Tahun. FKP terdapat juga di Sumatera Utara, terdiri dari berbagai bidang usaha yaitu kategori kuliner, industri jasa, kreatif, sosial wirausaha, dan technopreneur. Namun beberapa kendala yang dialami oleh wirausaha di FKP adalah kurangnya informasi mengenai langkah-langkah pengurusan perizinan PIRT dan sertifikasi halal, serta produk yang dihasilkan juga masih dibutuhkan edukasi kembali agar mendapatkan hasil produk yang menarik dan tahan lama serta memahami alur proses perizinan. Sedangkan hasil riset perguruan tinggi masih banyak juga yang belum menemukan mitra untuk hilirisasi hasil risetnya dalam sebuah produk yang bisa bermafaat untuk masyarakat dan dapat dikomersilkan. Tujuan kegiatan program PKM untuk memberdayakan, menguatkan partisipasi anggota FKP dalam proses perizinan, optimalisasi hasil riset perguruan tinggi (PT), sosialisasi dengan memberikan informasi mengenai kerjasama hasil riset dengan mitra yang sesuai untuk peningkatan nilai tambah dan komersialisasi. Optimalisasi sosial media sebagai sarana promosi, Metode pendekatan yang digunakan menjalin kerjasama dengan mitra, instansi terkait, metode pendidikan, teknologi tepat guna, metode sosialisasi, pelatihan pengemasan dan metode pendampingan perijinan PIRT dan Halal MUI. Hasil, Pelaksanaan PKM dilakukan di bulan Juni 2021, Hasil sosialisasi mendapatka respon baik dari mitra, dengan bersedianya mereka untuk membantu menyampaikan informasi ke anggotanya dan dari 40 peserta hanya 10 UKM yang sudah memiliki P-IRT dan 5 usaha yang sudah memiliki Label halal MUI, mitra memahami pentingnya inovasi untuk produknya dan perlunya proses higienis dan safety saat proses penjamah makanan, produksi, dan pengemasan.
