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

The Sars-Cov2 virus, also known as the Covid-19 pandemic, has led in a rise in the usage of immune-boosting supplement items. This situation resulted in higher prices and a scarcity of stock on the market. This program seeks to motivate and educate UPT Liwa Botanical Garden (KRL) employees about the necessity of utilizing herbs to boost body ’s immune system during the Covid-19 outbreak. The activity's target audience is workers, who interact often with tourists from various locations. Twenty persons participated, including KRL officials, Lumbok Seminung Kehati Park Managers, and KRL apprentice students. This activity takes the form of providing content, question and answer sessions, demonstrations on how to make herbal beverages, and training assessment using pre and post-test questionnaires. The results of the training implementation revealed an increase in participants' motivation and understanding of the importance of herbal functions and the skills of making herbal drinks, as evidenced by their enthusiasm in the discussion both before and after the demonstration of making herbal drinks.

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%.

Abstract

The amount of garbage that accumulates in the waters causes environmental damage which is getting worse. The breakdown of plastic waste into smaller particles that have been degraded is called microplastic. This study aims to analyze the number of particles, shapes, and types of microplastic polymers found in the water and sediments of Mahitam Island. The research location was determined by purposive random sampling with three stations based on plastic sources, namely Station I, Station II, and Station III, which had different characteristics from laboratory-based testing for seawater and sediment. Microplastic analysis on seawater samples was carried out by adding a solution of 70% ethanol, 30% H2O2, and 30% NaCl, and on sediment samples was carried out by adding a solution of FeSO4 (0.05 M), NaCl, and 30% H2O2. The content of the number of particles and the shape of microplastics were analyzed using a microscope, while the analysis of microplastic polymers using FT-IR. The first thing to do is to extract microplastics The forms of microplastic found are Fiber, Film, Fragments, and Pellets. The highest number of microplastic particles was the type of film for water samples at Station 1 and Station 2 for sediment samples. The types of polymers found in water and sediments on Mahitam Island are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS) which come from plastic waste. Microplastics are known to originate from the use of plastic originating from tourist activities and originating from the sea currents of Mahitam Island.
