Abstract

Bovine rumen bacteria consist of diverse microorganisms essential for processing manure, compost, and liquid organic fertilizer, enhancing soil fertility and nutrient availability while suppressing pests and pathogens. These bacteria include cellulose-digesting species such as Bacteroides succinogenes, Ruminococcus flavefaciens, and Ruminococcus albus, which produce cellulase enzymes for organic matter decomposition. Morphologically, cellulolytic bacteria are categorized into coccus forms (Ruminococcus flavefaciens and Ruminococcus albus) and rod forms (Bacteroides succinogenes and Butyrivibrio fibrisolvens), with Gram-positive and Gram-negative cell walls. This study examined the growth and morphology of bovine rumen bacteria in fermented liquid over three weeks. Colony counts increased from 4.75 × 10⁶ CFU/mL in week 1 to 2.92 × 10⁷ CFU/mL in week 2 and 6.2 × 10⁸ CFU/mL in week 3. Colony morphologies included colors (pink, yellow, blue center), sizes (small, medium, large), shapes (circular, irregular), elevations (raised, convex, unbonated), surfaces (smooth, mucoid), and edges (regular, irregular). Predominant bacterial cell shapes were bacillus, with Gram-positive staining. These findings underscore the potential of bovine rumen bacteria in organic waste fermentation and nutrient cycling.

Abstract

Sugar factories during the process of milling sugar cane stalks usually produce solid waste in the form of filter cake or filter cake or filter press mud which amounts to around 3.8% of the weight of the sugar cane. The accumulation of large quantities of filter cake is a source of serious environmental pollution for sugar factories and surrounding communities, whereas during the rainy season, piles of wet filter cake emit a foul smell and pollute the environment. On the other hand, filter cake can be used as organic fertilizer. Long-term application of filter cake fertilizer can increase the physical, biological and chemical fertility of degraded land. Application of filter cake organic fertilizer in sugar cane fields at PG Pradjekan PT. Nusantara Sugar Synergy provides benefits, including: minimizing sources of environmental pollution produced by PG. Pradjekan in the form of filter cake waste, utilizing filter cake waste produced from the process of milling sugar cane stalks into organic filter cake fertilizer, accelerating the decomposition process of filter cake by spraying the decomposer to become organic filter cake fertilizer, creating organic filter cake fertilizer from filter cake waste which can be applied to sugar cane land which is useful for increasing Soil organic carbon levels in sugar cane fields and PG Pradjekan PT. Synergy Gula Nusantara is able to produce and apply organic filter cake fertilizer to its sugar cane fields which is carried out when the sugar cane stalks are 2 months to 4 months old.

Abstract

Urban communities are generally communities that have homes with limited agricultural land. PKK RW 27 Tegal Boto Lor, Sumbersari District, Jember Regency, East Java has tried to utilize limited land for agricultural activities by planting trees and ornamental plants on the side of the road. Based on this, the Community Service Implementation Team helped provide innovation by introducing the application of the urban farming concept through wall gardening. The method used is through education and soft skill training with the aim of opening the community's insight and knowledge about the innovation of the urban farming concept through wall gardening activities. Based on the activities that have been carried out, there has been an increase in community knowledge with good criteria from 20% (pre-test) to 53.4% ​​(post-test).
