Abstract

Intensive shrimp culture has encountered many problems, such as declining water quality through disease caused by pathogenic microbes, which affected mortality. This study aimed to determine any potential probiotic from Bacillus sp. collected from mangrove in East Lampung, which could be used to improve the cultured shrimps' proteolytic and probiotic activity. This is a descriptive research with sampling and data collection of bacteria from many samples of mangrove. Result shows 128 isolates Bacillus from which then it has arrived at five potential probiotic Bacillus sp. The study five Bacillus sp. has been isolated with potential properties for probiotic (KPP212, IP121, UJ131, UJ132, SB141). Each isolate has characteristics with proteolytic property, growth in a wide range of pH 4–10 and osmotic stress (0–6% NaCl), non-pathogenic, ability for glucose fermentation, non-motile, and has negative catalase activity. The five potential Bacillus sp. can be used as probiotics for shrimp farming.

Abstract

−Eggshells are one of the organic waste that is commonly found and comes from households. Based on observations in the field, people generally have not done waste management properly such as separating organic and inorganic waste. However, the utilization of household waste in the form of eggshells has not been widely done by the community. The solution to overcome this problem is to conduct training for the community to utilize waste in the form of eggshells to be used both for nurseries and further processing as organic fertilizer to increase plant growth. The desired expectation in the implementation of this service is an increase in skills and knowledge in making organic fertilizer from eggshells. There was an increase in knowledge and skills of the service participants with a pretest score of 55.88 and post-test to 90.00. There was an increase in value of 34.12. The percentage increase in value is 62.86%.
