Abstract

Mangroves are a type of plant that grows in coastal areas and river estuaries, and are often exposed to sea tides. The mangrove ecosystem has an important role for the life of the biota along the ecosystem, such as shrimp. Therefore, the aim of this research is to assess the composition of shrimp associated with mangroves in the Lembar coast of West Lombok. Mangrove data were collected using transect and quadrant methods, while shrimp data was collected using seser nets. Next, data analysis was carried out descriptively and the relationship between shrimp density and mangrove density was analyzed using Pearson correlation. The results of the research found four species of shrimp, including Penaeus merguiensis, Penaeus monodon, Alpheus sp, and Litopenaeus vannamei. Apart from that, six mangrove species were found, including Avicennia alba, Avicennia marina, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa and Sonneratia alba. Furthermore, the shrimp density value on the Sheet coast is 1756 ind/ha/year, while the mangrove density value is 0.382 ind/m2. The relationship between shrimp and mangroves is based on Pearson correlation analysis, r2 value = 0.699. The conclusion of this research is that the level of correlation between shrimp density and mangrove density in the Lembar coast is in the medium category.

Abstract

The overall health of the body includes oral and dental health. The aftereffects of the 2018 Riskesdas show that most of the Indonesian populace (94.7%) has great tooth brushing propensities, specifically they have carried out the way of behaving of cleaning their teeth consistently. Sadly, however, only 2.8% of this number brush their teeth correctly, at least twice per day—in the morning after breakfast and at night before bed. The use of chlorhexidine as a mouthwash is a periodontal treatment because it has antiseptic properties, inhibiting plaque formation. The aim of this study was to determine the difference between gargling using Chlorhexidine Gluconate after brushing your teeth and not rinsing your mouth. The research process was carried out at the Karya Adi Husada Mataram Dental Health Academy and was carried out by observing samples between those who gargled using Chlorhexidine gluconate and those who did not gargle. The research results show significant results in the univariate analysis statistical test, namely from the results of statistical tests using the univariate analysis test, the count is 85,154 tables with α0.05, which is 14,6114, meaning the count is greater than the table so Ho is rejected. So it can be concluded that there is a difference in OHIS values ​​between those who gargle Chlorhexidine gluconate and those who do not gargle Chlorhexidine gluconate, where the OHIS value of Chlorhexidine gluconate mouthwash users is better than the OHIS value of students who do not gargle Chlorhexidine gluconate.

Abstract

The Population structure is the individuals within a population that can be grouped based on specific characteristics, such as age groups or age stratification, such as prereproductive, reproductive, and postreproductive stages. This study aims to assess the population structure of Echinoderms on the southern coast of East Lombok based on average size and determine association types. Data collection was conducted using the quadrant transect method. Subsequently, data analysis included average size values of Echinoderms, Association Index, and abundance (Di). The study identified eight species totaling 726 individuals across seven families. Among them, the species with the highest number of individuals in the Poton Bako area was Protoreaster nododus (27.82% of total individuals). Meanwhile, the species with the lowest number of individuals on Pantai Lungkak was Ophiocoma scolopendrina (0.55% of total individuals). The highest abundance value (Di) was found for Protoreaster nodosus at Poton Bako (0.20 ind/m2), while the lowest (Di) was found for Ophiocoma scolopendrina at Pantai Lungkak (0.00 ind/m2). The species with the longest average size was Synapta maculata (24.50±6.21 cm), included in reproductive stratification, and the smallest average size was for Ophiocoma scolopenderina (1.33±0.12 cm), included in reproductive stratification. There was an association of Echinoderms with seagrass beds, with a positive association observed in the Poton Bako area and a negative association observed in Pantai Lungkak.

Abstract

Indian mackerel (Rastrelliger kanagurta) is a small pelagic fish species that has economic value to the community. Overfishing without management causes population decline and negative impacts on fish stocks. This study aims to analyze the morphometric characteristics of indian mackerel at Tanjung Luar Fish Landing Base (PPI), East Lombok. Data from 72 fish were collected from January to April 2024 using observation method and quantitative statistical analysis. The results of descriptive analysis showed that indian mackerel landed in Tanjung Luar PPI had average morphometric characteristics such as total length (22.07cm), standard length (18.75cm), fork length (20,35cm), head length (5.23cm), head height (4.47cm), body height (5.7cm), eye diameter (1.32cm), first dorsal fin base length (3.27cm), second dorsal fin base length (2.89cm), pectoral fin base length (2.60cm), ventral fin base length (2.35cm), anal fin base length (2.61cm), tail shaft length (4.14cm), tail shaft height (0.96cm), lower tail fin length (4.28 cm), and upper tail fin length (4.24cm). Fish growth showed an isometric growth pattern, with body parts growing proportionally. The dominant fish sizes caught were in the juvenile category at 18.2-20.6 cm (44%) and adults at 25.7-28.1 cm (28%). However, the large number of juvenile fish caught indicates the potential for overfishing, requiring effective management such as setting minimum size and fishing time to maintain the sustainability of the fish population.

Abstract

Maggot is an organism that originates from the eggs of the BSF fly (Black Soldier Fly) which is usually known as a rotting organism because of its habit of consuming organic materials. Maggots can be an alternative feed because they have a fairly high protein content and are suitable as fresh fish feed or as raw fish feed ingredients. The study aims to determine the effect of the proportion of the combination of coconut pulp and fermented chicken manure on the population, weight and length of maggot (Hermetia illucens). This research method used an experiment with 6 treatments, 5 replicates for each treatment. The treatments applied were T1: 100% coconut pulp, T2: 95% coconut pulp + 5% chicken manure, T3: 90% coconut pulp + 10% chicken manure, T4: 85% coconut pulp + 15% chicken manure, T5: 80% coconut pulp + 20% chicken manure, T6: 75% coconut pulp + 25% chicken manure. Maggot maintenance started from 0-14 days of age.  The observed paramameter of the population were weight and length of maggot (Hermetia illucens). This study used a Complete Random Design (RAL) with 5 replicates and the data was analyzed using Analysis of Variance (ANOVA). Based on the results of statistical analysis, the combination of coconut pulp and fermented chicken manure on the population, weight and length of manggot (Hermetia illucens) (P < 0.05). The results of the research on the combination of coconut pulp and fermented chicken manure with different combinations showed that there were some differences. T6 treatment was able to show the highest results in population, weight and length of maggot (Hermetia illucens).

Abstract

Free radicals are compounds that can cause various diseases and can be inhibited with antioxidant compounds. One of the antioxidant compounds that can be obtained from natural sources is the kepundung plant (Baccaurea racemosa). This research aims to determine the fraction that contains flavonoid compounds and determine the percent inhibition of the fraction resulting from gravity column chromatography from the methanol extract of kepundung leaves (Baccaurea racemosa) using the DPPH method. Extraction used the sonication method and continued with fractionation using gravity column chromatography. A UV-VIS spectrophotometer was then used to measure the antiradical activity and perform a qualitative flavonoid and antioxidant test using TLC. The study's findings demonstrated that the yield of a 96% methanol extract of kepundung leaves was 17%, and that there were 15 sets of fractions produced by gravity column chromatography. Positive results for flavonoids and antioxidants were shown by fractions B, G, H, K, L, and N. The fraction with the highest antiradical activity was fraction L with a % inhibition value of 79,94%.
