Abstract

Studies about renewable energy are evolved continuously to decrease the needs of fuel oils that were diminished. One of the alternative energy sources that can be evolved is bioethanol due to the high amount of oxygen component in it hence it can be combustible and eco-friendly. Mesocarp is farming and trading waste of Cocos Nucifera (Coconut) that contains 40% lignin, 44,4% cellulose, and 15% hemicellulose. Delignification is a process of removing lignin from the materials thus it can produce the high purity of cellulose. As long as this, there were numerous studies that researched about lignocellulose biomass, however the least studies researched the impact of using delignification. Thereby, this study was done for figuring out the impact of HCl concentration and length of time to the decreased lignin content and the quality of bioethanol. The points of impacts that being focused on were 1M, 2M, and 3M HCl concentration, whereas the points of length of time impacts were about 60 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes. The decreased lignin content that was obtained is about 18,5% and the finest bioethanol is 97,38 %, 15oC for flash point, 3,8402 cPs for viscosity, and 0,8252 gr/cm3 for density from delignification using 3M HCl for about 150 minutes. Greater HCl concentration to delignification, greater quality of bioethanol that is produced, therefore can be applied to alternative fuel oils for vehicle. Keywords: bioethanol, delignification, HCl, mesocarp

Abstract

This service activity provides benefits to CV Pandawa Farm, because it uses cow dung into environmentally friendly fuel energy. Sarnubi CV Pandawa Farm's Cattle Farm is a cattle farm that has been established for more than 10 years. more than 30 individuals. The location of this farm is in the Sukawinatan area which is not far from the Palembang City Waste Landfill. The environmental conditions of this farm are not good because health management of cow dung has not been implemented here. Processing cow dung into biogas can have a good impact on the environment because it maintains environmental cleanliness. Apart from that, biogas can be used to replace fossil fuels. CV Pandawa Farm does not yet understand how to process cow dung into biogas. In this socialization, counseling was provided by providing knowledge and understanding of how to process cow dung waste combined with tofu industry waste into biogas using a Fixed Dome Digester

Abstract

Hidrogen merupakan gas ramah lingkungan yang dapat dihasilkan melalui proses elektrolisis air untuk memisahkan hidrogen (H₂) dan oksigen. Pada penelitian ini digunakan elektroliser sel kering dengan membran polyvinyl alcohol (PVA) sebagai pemisah antara dua elektroda baja tahan karat 316 guna memperoleh komposisi hidrogen yang lebih tinggi. Penerapan membran PVA terbukti mampu meningkatkan produksi hidrogen secara signifikan dibandingkan tanpa penggunaan membran. Selain itu, pemanfaatan elektrolit KOH dalam proses elektrolisis mampu meningkatkan arus listrik, yang secara linier berbanding lurus dengan kenaikan kebutuhan daya listrik serta menghasilkan produksi gas hidrogen yang lebih besar. Gas hidrogen yang dihasilkan kemudian dikonversi menjadi energi listrik menggunakan sel bahan bakar hidrogen untuk menyuplai stasiun pengisian daya dan telepon sebagai beban, dengan status pengisian dikategorikan berhasil (CS) atau gagal.

Abstract

Ketersediaan sumber daya energi fosil seperti minyak bumi, gas alam, dan batu bara semakin menipis serta tidak dapat diperbarui, sehingga pengembangan energi terbarukan menjadi solusi penting dalam memenuhi kebutuhan energi nasional. Penelitian ini bertujuan untuk mengkaji produksi bioetanol dari dua jenis biomassa lignoselulosa, yaitu tongkol jagung dan kulit singkong, melalui proses Simultaneous Saccharification and Fermentation (SSF) dengan penambahan Aspergillus niger. Variabel bebas yang digunakan adalah waktu fermentasi (3–7 hari) dan massa ragi (2% dan 4% m/v). Hasil fermentasi dimurnikan melalui proses distilasi, kemudian dianalisis menggunakan refraktometer dan Gas Chromatography–Mass Spectrometry (GC-MS) untuk mengetahui kadar etanol yang dihasilkan. Hasil terbaik dari tongkol jagung diperoleh pada indeks bias sebesar 1,3498 dengan kadar etanol 52% (refraktometer) dan 66,02% (GC-MS). Sementara itu, kulit singkong menghasilkan indeks bias tertinggi sebesar 1,3510 dengan kadar etanol 56% (refraktometer) dan 48,41% (GC-MS). Hasil penelitian ini menunjukkan bahwa baik tongkol jagung maupun kulit singkong memiliki potensi sebagai bahan baku bioetanol, dengan variasi waktu fermentasi dan massa ragi yang berpengaruh terhadap kualitas bioetanol yang dihasilkan.
