Abstract

Vannamei shrimp is one of the shrimps that are being cultivated in Indonesia because it has superior quality compared to other types of shrimp. Cultivation activities cannot be separated from disease attacks that attack cultured commodities. One of the diseases that attack vannamei shrimp is Acute Hepatopancreatic Necrosis Disease (AHPND). The disease is caused by Vibrio parahaemolyticus bacterial infection (VpAHPND) which produces toxins and causes death in shrimp with mortality reaching 100%. Therefore, it is necessary to conduct research or early detection in the aquaculture area of Bengkalis Regency using the PCR (Polymerase Chain Reaction) method. The method used is the survey method. This research was conducted from March to April 2023. The results of this study are the prevalence of AHPND (Acute Hepatopancreatic Necrosis Disease) in vannamei shrimp (Litopenaeus vannamei) in the Bengkalis Regency Aquaculture area is 0% with the category of infection never. AHPND examination by PCR method using AP4 primer measuring 230 bp showed that vannamei shrimp samples from Bengkalis District, Bantan District, and Bukit Batu District of Bengkalis Regency were negative for AHPND. The morphological condition of vannamei shrimp from the three research locations did not show any clinical symptoms of shrimp infected with AHPND

Abstract

Macrozoobenthos are organisms that live sedentary (sessile) and have varying adaptability to environmental conditions. In addition, the level of diversity found in the aquatic environment can be used as an indicator of pollution. The purpose of this study was to determine the type, abundance, diversity, and distribution pattern of macrozoobenthos in the intertidal zone. This research was conducted in the waters of Pasumpahan Island. The method used in this study was a survey method, while sampling was carried out using three stations and each station consisted of 3 transects and three sub-zones using a 1m x 1m quadrant map. The results of this study found that the abundance value at each station was 4.22-5.78 ind/m2, while the abundance in the sub-zone ranged from 3.00-7.67 ind/m2, the diversity index (H') at the study sites ranged from 1.65-2.31, which means 1.0 ≤H' < 3.0 and the diversity of macrozoobenthos at the study site was categorized as moderate. The distribution pattern (Id) of macrozoobenthos at locations was clustered with a value of 1.05-1.28. The results of the One Way ANOVA test between stations obtained a value of 0.001 where p <0.05, which means H0 was rejected and there was a significant difference between the 3 stations, followed by the LSD test to find out which average between stations was the most different real

Abstract

Sironjong Gadang Island is one of the islands in the Mandeh Tourism area in Pesisir Selatan Regency, West Sumatra, Indonesia. One of the ecosystems affected by tourism activities is coral reefs. Monitoring the coral reefs' condition and the abundance of coral fish in the Chaetdontidae family is carried out to find out this. This research uses survey research methods. The temperature measurement results obtained an average of 30.2oC, current speed measurements received an average of 0.12 m/s, salinity measurements obtained an average of 30 ppt, and brightness measurements show that the brightness of these waters is 9 m. Tide measurements in the waters of Sironjong Gadang Island, carried out on March 7–8, 2023, are double daily tides (semi diurnal tide). Then, the results from the coral reef cover of Sironjong Gadang Island waters obtained a percentage ranging from 2.34 - 12.83%, with an average rate of live coral reef cover of 5.96%, which is included in the poor category. Furthermore, the results at each research station in the waters of Sironjong Gadang Island showed that 54 coralfish individuals were found, with the number of coralfish at each depth ranging from 4 - 10 individuals. The most common types of coral fish are species. Acuminate had 18 individuals; the fewest types of coral fish found were Chaetodon trifasciatus and C. tristichous, each numbering two individuals. There is a solid relationship between live coral reef cover and the abundance of coral fish in the Chaetodontidae family, where live coral reef cover influences the plenty of coral fish by 61.11%, which means that the higher the percentage of live coral cover, the higher the value of coral fish abundance

Abstract

In the coral reef ecosystem, there is a food source for small fish, which are prey for various kinds of associated biota; one of the biota that lives in the coral reef ecosystem is megabenthos. Megabenthos is influenced by the quality of the coral reef ecosystem, where if conditions are good, the coral will have a greater chance of high megabenthos diversity. This research was carried out in March 2023 in Setan Island, West Sumatra. This research analyzes the relationship between coral reef conditions and megabenthos abundance. The method used in this research is a survey method. Observations of coral reef cover were carried out using the Underwater Photo Transect (UPT) method, and megabenthos abundance was measured using the Benthos Belt Transect (BBT) method. Observations were carried out at four stations (3 and 6 m deep) with a transect length of 50 m. Based on the average value of the percentage of coral reef cover, it is still categorized as being in poor condition, namely 18.87%. There is a relationship between the percentage of live coral reef cover and the abundance of megabenthos with a percentage of 55.27%, with the types of megabenthos clams (Tridacna sp), sea cucumbers (Holothuria sp), snails (Trochus sp), lobsters (Panulirus sp), fur pigs (Diadema sp), snails (Drupella sp), and starfish (Acanthasper sp).

Abstract

Mushroom coral (Fungiidae) is one of the families of hard corals (scleractinian) that live off the substrate (free-living), and most of the mushroom coral habitat is found on the reef slope, which has a substrate of broken coral. This study aimed to analyze the abundance and diversity and determine the differences in abundance of mushroom corals at different depths. This research was conducted in March 2024 in Pasumpahan Island, West Sumatra. This study used the survey method and belt transect method. The sampling location was divided into three stations consisting of 3 sampling points. Station I is located in the tourist area, Station II is in the dock area, and Station III is in the area facing the open sea. The results showed that the highest abundance based on depth was found at station III with a depth of 7 m, namely 4357.14 ind/Ha and the lowest abundance at station II with a depth of 5 m, namely 1285.71 ind/Ha. The t-test results obtained a significant value of less than 0.05, namely 0.048, which means that the abundance of mushroom corals at different depths is significantly different. The diversity index ranges from 1.930 to 2.013, which shows that the level of diversity of mushroom corals in the waters of Pasumpahan Island is classified as moderate

Abstract

Hypertension is one of the main health problems at risk of causing cardiovascular diseases, such as heart attack and stroke, which requires special attention in coastal areas, including Teluk Rhu Village, North Rupat Sub-district, Bengkalis Regency. Based on an initial survey, the incidence of hypertension in this village is quite high, especially among fishermen who have an irregular lifestyle and limited knowledge about the risks of hypertension. In order to overcome this problem, Community Service activities (PKM) were carried out on May 20, 2024 with the aim of increasing community knowledge and awareness about hypertension through counseling, health checks, and distribution of educational materials. This activity also involves students as facilitators and brings health services closer to people living in remote areas.The evaluation results showed that this program succeeded in increasing community knowledge about hypertension and its prevention measures. Of the 30 participants who took part in the blood pressure check, 10 of them were diagnosed with hypertension and given recommendations for treatment and regular check-ups. In addition, this activity also introduced technology in the form of educational media such as posters and videos to deepen the community's understanding of the symptoms and management of hypertension. Although the program has been running well, there is still a need to improve health facilities and early detection to expand the scope of education and treatment, especially for high-risk communities. With the establishment of a hypertension club and improved health services, it is hoped that the prevalence of hypertension can be reduced and the quality of life of the people of Teluk Rhu Village improved
