Abstract

Cassava leaves have a potential to be an alternative feed as it has high crude protein content, as well as essential vitamins and minerals. This research aims to find the effective combination dose of inoculant and nutrient additive in improving sensory characteristics and lactic acid in fermented cassava leaves (Manihot esculenta). This study used four treatments and five replications. T0 (Fresh cassava leaf without additives), T1 (fermentation with 40% EM4, 20% ml Viterna, and 40% ml MOL), T2 (20% EM4, 40% Viterna, and 40% MOL), and T3 (40% EM4, 40% Viterna, and 20% ml MOL). All additives were applied at a total dose of 0.5% (v/w) to the fresh weight of the material, and fermented anaerobically for 14 days. Data were analyzed using analysis of variance based on a Completely Randomized Design and Duncan's test. The results showed that T3 produced the highest lactic acid content (P <0.05) compared to other treatments. Treatments T2 and T3 produced a brownish-yellow silage color that was significantly different (P<0.05) from treatments T0 and T1, which showed a yellowish green color. The aroma produced in T2 and T3 was moresour (P<0.05) than T0. The treatment did not have a significant effect on silage texture (P>0.05). The combination of inoculants and nutrient additives had a significant effect (P<0.05) on the mold coverage score, with a tendency for a decrease in the mold coverage score from T1 to T3. It was concluded that The combination of inoculants and nutrient additives can improve the quality of cassava leaf fermentation. The best result is obtained in T3 which produces the highest lactic acid content and improved sensory characteristics.

Abstract

Agricultural waste and livestock manure that are not properly utilized can cause environmental pollution. This community service aims to reduce environmental pollution through the treatment of agricultural waste and fermented manure to be used as maggot growth media at Arjuna Farm. Maggots are a source of animal protein with good nutritional value, containing 45-50% crude protein. The production of maggots from livestock and agricultural waste can serve as a source of nutrition for livestock. The community service methods include fermenting agricultural waste and manure to create maggot growth media, maggot cultivation training, and the production of dry maggot products that can be used as a source of animal protein feed for poultry. This program also contributes to increasing the income of Arjuna Farm through the produced dry maggot products. It is hoped that through this community service, farmers can access appropriate technology for processing fecal and agricultural waste using fermentation technology to produce a good growth medium for maggots. The results of this service have an impact on environmental preservation and reducing the negative effects of agricultural and fecal waste, as well as contributing to improving their economic welfare. The observation percentages after evaluation at Arjuna Farm were not significantly different from the expected results, with an average of 74% out of 92% in terms of waste processing and farmers' income.
