Abstract

The Glagah consortium is a mixed culture of various microalgae and bacteria isolated from Glagah Beach, Yogyakarta. Cobalamin and thiamine, which are given by symbiotic bacteria, are assumed will increase biomass. This study aimed to determine the effect of cobalamin and thiamine on microalgae biomass production in the Glagah consortium. The microalgae of Glagah consortium were cultivated for 10 days with vancomycin and gentamicin antibiotic as treatment and without antibiotics as a control. The parameters measured included the number of bacterial colonies, cobalamin and thiamine levels measured by LC-MS, chlorophyll a and b levels, cell density of microalgae and dry biomass. The highest level of cobalamin and thiamine was in the Glagah consortium without antibiotics. Cobalamin and thiamine increased in the exponential phase along with the increasing Staphylococcus sp. colonies. The Quantity of Staphylococcus sp. colonies in the exponential phase was 62.105 (cfu/mL). The level of cobalamin in the exponential phase was 2.33 µg/L and the level of thiamine in the exponential phase was 49.71 µg/L. The highest productivity dried weight biomass was 0.0134 g/L/day in the day-6th on the Glagah consortium without antibiotics. This result showed that microalgae and bacterial interaction was mutualism symbiosis involving cobalamin and thiamine that increased in the exponential phase along with the increasing Staphylococcus sp. colonies. This interaction was able to increase biomass microalgae.

Abstract

Kecinan Beach is one of the beaches on Lombok Island with many tourism activities. The activities in Kecinan Beach can influence the water quality, as the waters may receive waste from surrounding areas, leading to potential pollution or a decline in water quality. Phytoplankton are living organisms that can indicate whether a water body is polluted, which can be marked by changes in the community structure of phytoplankton, particularly in abundance and diversity. Water quality based on phytoplankton diversity as a bioindicator in Kecinan Beach has not been reported. This study was conducted to analyze the water quality of Kecinan Beach based on phytoplankton diversity as a bioindicator. Samplings were carried out in 9 sites in 3 stations during the month of March to June 2024. Samples were collected using a plankton net of 20µm mesh size. Samples were preserved in 4% formalin preservation and laboratory observation was conducted in the biology laboratory of FMIPA University of Mataram. The study identified 56 species from  3 classes, 21 families and 30 phytoplankton genera. The phytoplankton abundance in the coastal waters of Kecinan Beach was 126.667 ind/L. The species dominance index of phytoplankton of coastal waters of Kecinan Beach was 0.258, indicating no species dominance to each other. Rhabdonema arcuatum was identified as the highest (158%) species importance value. The species diversity index of phytoplankton of the coastal waters of Kecinan Beach was a moderate category. Based on the species diversity index, it can be said that the waters of Kecinan Beach are not polluted.

Abstract

The presence of Crustacea plays an important role in the processes occurring within seagrass bed areas. One of the coastal waters that contains seagrass beds is Kecinan Beach. This beach is also frequently used by the local community for madak activities, and the high frequency of such activities poses a threat to the seagrass ecosystem and the diversity of Crustacea. Due to the lack of available data on Crustacea in the Kecinan Beach area, this study is necessary to understand the community structure of Crustacea in the seagrass ecosystem of Kecinan Beach, Pemenang District, North Lombok. Data were collected using the line transect method, with each transect measuring 50 meters in length. Along each transect, 1×1 m² quadrat plots were placed. The Crustacea community structure found in the seagrass ecosystem of Kecinan Beach, Pemenang District, North Lombok, consisted of 14 families and 31 species, with a total of 155 individuals. The diversity index at stations I, II, and III was classified as moderate. The evenness index at stations I and II was high, while the evenness index at station III was moderate. The dominance and abundance indices indicated that each station had low species dominance and low abundance.

Abstract

High blood pressure, also known as hypertension, is a medical condition that affects blood pressure and can lead to complications such as stroke and heart disease. Hypertension is suffered by many people living in coastal areas due to an unhealthy lifestyle and consuming salty fish. To reduce the number of people with hypertension in coastal areas, community service activities related to hypertension management were carried out. The methods used in the community service were problem identification with the Delbecq (non-scoring method) method, data collection through interviews with questionnaires and observations of 70 participants, problem intervention through poster counseling and tension checks, data analysis using univariate analysis. The results of the community service were dominated by 55 women (79%) and middle-aged (45-59 years) 46 people (66%). The results of the questionnaire search showed that as many as 60 people (86%) respondents had heavy physical activity, 39 people (56%) respondents had a good level of knowledge and hypertension management, 42 people (60%) were known to often consume salted fish and 48 people (69%) were found to have hypertension. The high rate of hypertension sufferers in the coastal area of Kampung Melayu is due to the lack of counseling that focuses on dietary management and increasing public awareness about the risk of hypertension related to the consumption of high-sodium foods.
