Abstract

Bioethanol is an alternative fuel derived from biological feedstock used to decrease the reliance on fossil fuels because of increasing energy consumption associated with population growth and increased use of oil fuels. Bioethanol production has been widely conducted using several types of algae, but the optimal conditions for the hydrolysis and fermentation processes are not explained in more detail. Therefore, this study focuses on determining the optimal conditions for hydrolysis and fermentation to maximize the bioethanol yield. This study uses optimization based on the hydrolysis time, temperature, and pH to increase the reducing sugar content using high-performance liquid chromatography in the enzymatic hydrolysis process. The process consists of liquefaction and saccharification steps, where 4% α-amylase enzyme and 2%, 3%, and 4% glucoamylase are used. Results showed that the optimal conditions for the hydrolysis time were 180 min at temperatures of 70 °C to 80 °C. The enzymatic hydrolysis process is conducted under optimal conditions, followed by the fermentation process. Finally, the distillation process was performed with a maximum bioethanol yield of 25.0%.

Abstract

The development of environmentally friendly products is an innovative solution to minimizing the harmful effects of waste on the environment. This innovation development program aims to formulate innovative strategies for developing Evator Bio-Foam products, made from rice husks, specifically for students through an entrepreneurship-based approach. Evator Bio-Foam, a rice husk-based product, is specifically targeted at university students through an entrepreneurship-based approach. Evator Bio-Foam is a biodegradable packaging material made from a mixture of rice husks, soybean flour, and yeast, which is fermented and molded into a functional alternative to Styrofoam. The product is lightweight, water-resistant, food-safe, and decomposes naturally within a relatively short time. The strategy employed in this program integrates learning, creativity, and entrepreneurship to increase students’ awareness of environmental sustainability while providing them with essential business skills. The methods used include training, workshops, and business simulations focusing on production, marketing, and product management. The results show that this approach enhances students’ understanding of environmentally friendly innovation and encourages active involvement in developing sustainable businesses. This educational model not only supports environmental conservation efforts but also creates new opportunities in entrepreneurship that are relevant to market needs. Thus, it offers a viable alternative for cultivating a generation that is environmentally conscious and oriented toward business innovation.Pengembangan produk ramah lingkungan menjadi solusi inovatif untuk mengurangi dampak negatif limbah terhadap lingkungan. Program pengembangan inovasi ini bertujuan untuk merumuskan strategi pengembangan produk Evator Bio-Foam berbahan dasar sekam padi, khususnya untuk mahasiswa, melalui pendekatan berbasis wirausaha. Evator Bio-Foam merupakan kemasan biodegradable yang dibuat dari campuran sekam padi, tepung kedelai, dan ragi, yang difermentasi dan dicetak menjadi produk pengganti styrofoam. Produk ini bersifat ringan, tahan air, aman untuk makanan, serta mudah terurai secara alami dalam waktu relatif singkat. Strategi yang digunakan dalam program ini mengintegrasikan pembelajaran, kreativitas, dan kewirausahaan guna meningkatkan kesadaran lingkungan mahasiswa sekaligus membekali mereka dengan keterampilan bisnis. Metode yang digunakan meliputi pelatihan, workshop, dan simulasi bisnis yang berfokus pada proses produksi, pemasaran, dan pengelolaan produk. Hasil program menunjukkan bahwa pendekatan ini mampu meningkatkan pemahaman mahasiswa tentang inovasi ramah lingkungan serta mendorong keterlibatan aktif dalam pengembangan usaha berkelanjutan. Model edukasi ini tidak hanya mendukung pelestarian lingkungan, tetapi juga menciptakan peluang baru di bidang kewirausahaan yang relevan dengan kebutuhan pasar. Dengan demikian, model edukasi ini dapat menjadi alternatif solusi untuk membangun generasi muda yang sadar lingkungan dan berorientasi pada inovasi bisnis.

Abstract

Waste that is not managed properly in Neuheun Village, Aceh Besar Regency, can cause health and environment problems. Therefore, this service activity aims to provide the people of Neuheun village with the knowledge and skills of making organic fertilizer in a simple way. The fertilizer making is carried out through short training with raw materials that are reachable by the village community. The target of theses activities is housewives in the village, the majority of whom do not work and spend their time taking care of the household. Apart from filling the time, this activity can add insight, self-efficacy, and improve family health and economic life. These activities were attended by 20 housewives who are members of the recitation of the women of Neuheun Village. These activities take place through counseling and direct training stages. Counseling was provided through the distribution of reading materials and delivery of materials followed by the organic fertilizer making. The evaluation results show the enthusiasm of the participants in participating in the training, and they are able to make organic fertilizer. Making fertilizer is expected to be a side business and increase public knowledge about the benefits of organic fertilizers.
