Abstract

Coconut pulp has potential as animal feed but is limited in poultry diets due to its high fiber content and low protein levels. Fermentation using indigenous microorganisms offers a practical approach to improving its nutritional value. This study aimed to evaluate the nutritional quality of coconut meal using indigenous microorganisms (IMOs). The initial phase of the study involved producing IMOs, followed by measuring pH, total colony, and cellulase and mannanase enzyme activities. IMOs were applied to ferment coconut meal using a completely randomized design with four treatments (0, 7, 14, and 21 days) and four replications. Observed parameters included cellulase and mannanase enzyme activities, pH, crude fiber, crude protein, crude fat, and nitrogen-free extract. The characteristics of IMOs were analyzed descriptively, while enzyme activities and the nutritional content of coconut meal were analyzed using ANOVA and Duncan’s Multiple Range Test. The results showed that IMOs had a pH of 3.3, were dominated by lactic acid bacteria with a total colony of 5.4 × 10¹² CFU/mL, had cellulase activity of 2.1 U/mL, and had mannanase activity of 7.73 U/mL. Cellulase activity at 7, 14, and 21 days was significantly higher (P<0.01), while mannanase activity was highest at 21 days (P<0.01), with the lowest pH observed at 14 and 21 days. The lowest crude fiber and crude fat content, as well as the highest crude protein content (P<0.01), were observed at 14 days of fermentation. Fourteen days of fermentation were identified as the optimal duration for enhancing the nutritional quality of coconut pulp.

Abstract

Kamang Magek District is one of the sub-districts located in the eastern part of Agam Regency. Many small and medium enterprises (SMEs) are developing in Kamang Magek District, several UKM and farmer groups produce various by-products of organic waste which often become environmental problems. In addition to MSME waste, there is also household waste and market waste which often cause environmental pollution. These wastes can be used as feed for maggot development. Maggot cultivation apart from being a solution to environmental pollution is also a good source of protein for poultry feed which can increase livestock productivity. The community problems encountered in Kamang Magek District are the large amount of organic waste that pollutes the environment, the low productivity of livestock and the income of farmer groups. Community service is carried out through lectures, discussions, socialization of science and technology and demonstrations of how and how to apply maggot as animal feed. The Community Service was held in the BPP Hall of Kamang Magek District attended by 15 duck breeders, chicken breeders and catfish breeders selected by BPP Kamang Magek District. Based on the discussion results, more than 75% of breeders only provide feed in the form of rice bran and household waste residue and only 15% of breeders provide feed in the form of self-formulated feed using corn, bran and concentrate purchased at the poultry shop and 10% of breeders provide concentrate feed that has become the result of a feed factory formulation. Of all the breeders, there are no breeders who use maggot as feed for their livestock, this is because there are no breeders who have succeeded in cultivating maggot even though they have tried several times but failed. Based on the results of discussions with participants, breeders are interested in developing maggot cultivation because of the large amount of waste used as maggot feed as a cost-efficient solution for duck or chicken feed.
