Abstract

Bioethanol is ethanol derived from biological sources. Bioethanol can be produced from plants that contain many starch and cellulose compounds using the help of yeast activity. One of them is pineapple peel which can add a variety of basic materials for bioethanol production which is economical and easy to obtain. This study aims to analyze the effect of acid hydrolysis on glucose content, analyze the effect of fermentation time and the effect of yeast weight on bioethanol characteristics. This research has been done before and only focused on one catalyst. What has never been done is comparing the two catalysts. The research was conducted using hydrolysis fermentation and distillation using hydrochloric acid and citric acid catalysts with yeast weight variation of 12, 15, and 17 grams, fermentation time variation of 2, 3, 4, and 5 days. In this research, glucose test, density analysis, yield analysis, and GC-MS were conducted. The results of this study showed that the best results in the treatment of hydrochloric acid catalyst at a yeast weight of 15 grams, and obtained glucose levels of 6.90% for hydrochloric acid and 5.10% for citric acid, density test obtained the highest results at a yeast weight of 15 grams 4 days 0.8288 gr / ml for hydrochloric acid catalyst and the lowest density obtained at a yeast weight of 17 grams 5 days 0, 8168 gr/ml, yield analysis obtained at the amount of 15 grams of yeast with a fermentation time of 14 days of 4.3536% in the treatment of hydrochloric acid catalyst and 3.8557% in the treatment of citric acid catalyst fermentation time of 3 days, GC-MS test showed that ethanol contained in the test sample.

Abstract

Tebu adalah jenis tanaman C4 yang adaptif di iklim tropis, merupakan sumber utama sukrosa. Proses produksi gula menghasilkan limbah berupa ampas tebu yang kaya akan selulosa, yang memiliki struktur gugus hidroksil (-OH). Gugus hidroksil ini memungkinkan terjadinya ikatan hidrogen dengan senyawa polar seperti asam lemak bebas. Adsorpsi adalah teknik pembersihan senyawa pengotor yang memanfaatkan gaya tarik-menarik antara permukaan adsorben dengan molekul-molekul adsorbat. Penelitian ini bertujuan mengevaluasi efisiensi karbon aktif dari ampas tebu sebagai adsorben untuk mengurangi kadar asam lemak bebas, dengan memvariasikan massa adsorben dan waktu kontak. Proses pembuatan karbon aktif dilakukan pada suhu 300„ƒ selama 1 jam, lalu di aktivasi menggunakan HNO3 10% selama 24 jam. Penelitian ini memiliki variabel bebas berupa waktu adsorpsi yaitu 50, 80, 110 dan 140 menit serta massa adsorben pada 6, 7, 8 dan 9 gram. Proses adsorpsi karbon aktif dilakukan pada minyak jelantah, Karakterisasi karbon aktif dilakukan menggunakan SEM (Scanning Electron Microscopy) untuk mengamati morfologi permukaan dan XRF (X-Ray Fluorescense) untuk mengidentifikasi unsur penyusunnya. Hasil penelitian menunjukkan bahwa kadar FFA terendah (0,17%) diperoleh pada kondisi adsorpsi selama 140 menit dengan massa 9 gram karbon aktif, sedangkan efisiensi penyerapan tertinggi (90%) juga tercapai pada kondisi yang sama. Analisis data isoterm menunjukkan kesesuaian dengan model Langmuir, dengan persamaan y = 45,043x + 2,0685 dan nilai R² = 0,9936.

Abstract

UMKM kuliner di Desa Uteunkot, Kota Lhokseumawe, memiliki potensi ekonomi yang signifikan, namun masih menghadapi kendala dalam pemasaran digital, terutama akibat rendahnya literasi dan keterampilan penggunaan platform e-commerce. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas digital serta pendapatan pelaku UMKM kuliner melalui pelatihan dan pendampingan intensif. Metode yang digunakan meliputi, pelatihan literasi digital,  praktik langsung penggunaan platform e-commerce Shopee dan WhatsApp Business, serta pendampingan strategi pemasaran online berbasis konten dan promosi digital selama 3 bulan. Kegiatan ini melibatkan 5 pelaku UMKM kuliner sebagai peserta aktif. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada kompetensi digital peserta, ditandai dengan 90% peserta mampu mengoperasikan platform e-commerce secara mandiri. Selain itu, terjadi peningkatan rata-rata penjualan sebesar 20–30% dalam kurun waktu dua bulan setelah implementasi, serta perluasan jangkauan pasar hingga ke luar wilayah kota. Program ini juga mendorong perubahan pola pemasaran dari konvensional ke digital secara berkelanjutan. Dengan demikian, kegiatan ini berkontribusi dalam mempercepat transformasi digital UMKM serta memperkuat ekonomi lokal di era digital.

Abstract

Abstract. Bioethanol is an alternative energy sourced from environmentally friendly raw materials from wastes that contain a lot of lignocellulosic such as HVS paper. Paper contains about 85% cellulose, 8% hemicellulose, 5% lignin and the rest is in the form of ash compounds. Bioethanol is ethanol produced from the fermentation of glucose (sugar) followed by a distillation process. This study aims to analyze the effect of a combination of fermentation time and concentration of sulfuric acid on bioethanol. The highest yield of beathanol was obtained at a hydrolysis concentration of 6.5% with a 7-day fermentation time of 3.45%. Bioethanol density that was close to standard was 3.5% acid concentration with 3 and 5 days fermentation. Moreover, at 3.5% acid concentration showed the closest bioethanol viscosity to the standard value with all conditions synthesized acidic bioethanol with pH ranged from 6 to 6.5Keywords:Bioethanol, Fermentation, HVS paper, Sulfuric acid
