Abstract

Capacity building can be done in two ways, namely through hard skills (work skills) and soft skills (personal and behavioral skills). Soft skills is a sociological term that refers to personality characteristics, social attractiveness, negotiation skills, personal habits, caring, and optimism. Soft Skills are personality and behavioral abilities and skills. These soft skills complement hard skills as technical requirements for a job. The objectives of the service activities that will be carried out include (a) providing understanding to village officials about the capacity building needed in community service and (b) providing skills in community service in the form of personal skills and behavior so as to improve the quality of community service. Village officials and other community servants have not been able to provide maximum services due to lack of discipline and responsibility, lack of cooperation both among officers and with the community. Village officials and other community servants such as posyandu officers, members of village PKK mobilizers, are officers who provide services to the community. Village officials and other community servants have not been able to provide maximum services due to lack of discipline and responsibility, lack of cooperation both among officers and with the community. This phenomenon is an indicator of a lack of ability or capacity as a public servant. Their main tasks and functions related to village government are quite well understood, but the supporting factors for their tasks which are directly related to their personal capacity as servants are still lacking. Capacity building through outbound activities is an outdoor activity which is training in the form of games to build personal abilities and behavior in improving the quality of service to the community. Capacity building activities can build aspects of personality and behavior of village officials as soft skills which are an inseparable part of basic skills in the form of basic tasks (hard skills) and functions as village government officials.

Abstract

Padang City is one of the cities with a long coastline. The Padang City government has made many reforms to manage the beach area as a tourist attraction. This research aimed to determine the comparison of macrozoobenthos community structure, including species composition, species abundance, relative abundance, diversity index, similarity index, dominance index, and distribution patterns in the reclaimed and natural beaches of Padang City, West Sumatra Province. The method used was purposive sampling with sample collection using the transect method. The results of this study indicate that the water quality in Padang City, West Sumatra, is sufficiently good to support macrozoobenthos life. The highest species abundance of macrozoobenthos was found at the Reclamation Beach Station. The macrozoobenthos species found belong to 2 classes: Gastropoda and Crustacea. The Gastropoda class consists of 4 species: Babylonia spirata, Pila ampullacea, Pila occidentalis, and Nerita fulgurans, while from the Crustacea class, three species were found: Ashtoret lunaris, Hemigrapsus takanoi, and Emerita sp. Meanwhile, the lowest abundance was found at the Natural Beach Station, where the species belonging to the Crustacea class, specifically H.takanoi, was found. The species diversity of macrozoobenthos at the Natural Beach Station is considered low but moderate at the Reclamation Beach Station. Similarity at the Natural Beach Station is low, while at the Reclamation Beach Station, it is high. Additionally, there is a dominant species at the Natural Beach Station, whereas no dominant species were found at the Reclamation Beach Station. The distribution pattern of macrozoobenthos in the coastal waters of Padang City is categorized as clustered distribution

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

Abstract

The mangrove ecosystem in Dompas Village, Bengkalis Regency, has been degraded due to anthropogenic activities and pollution from both land and sea. This study aims to analyze the condition of the mangrove ecosystem and the urgency of conservation in the coastal area of Dompas Village. The methods used were field surveys, observation of the mangrove ecosystem, measurement of physical and chemical parameters of the water, and interviews with the local community. The results of the study show that the mangrove ecosystem in Dompas Village has experienced a decline in quality due to uncontrolled logging, pollution from the Pertamina Sungai Pakning oil refinery, and shipping activities. Mangrove degradation has caused coastal abrasion, a decline in biodiversity, and a reduction in fishery resources. Conservation of the mangrove ecosystem is crucial to maintain ecological functions, protect the coastline, preserve biodiversity, and support the livelihoods of coastal communities. Rehabilitation efforts, community education, enforcement of regulations, and integrated coastal zone management are needed to ensure the sustainability of the mangrove ecosystem in Dompas Village.

Abstract

Potential of marine photosynthetic bacteria (MPB) and their biopigment extracts as antimicrobial agents against two major aquatic pathogens, Aeromonas hydrophila and Staphylococcus aureus. The research was conducted from February to April 2025. Six MPB isolates were cultured under laboratory conditions to induce pigment production. Biopigments, natural pigments produced by microorganisms, exhibit antimicrobial and antioxidant properties. Pigment extraction was performed using acetone and ether, followed by evaporation to obtain concentrated pigment extracts. The antimicrobial activity of both MPB suspensions and their biopigment extracts was tested using the disc diffusion method on Mueller-Hinton Agar (MHA) media. The results showed that the MPB suspensions produced no inhibition zones against either pathogen. In contrast, the biopigment extracts demonstrated weak antimicrobial activity, with inhibition zone diameters ranging from 1 to 4 mm, a classification of weak. However, the ability of biopigment extracts to inhibit bacterial growth, even at low levels, suggests the presence of bioactive compounds with potential antimicrobial activity. These findings suggest that MPB-derived biopigments may serve as a natural alternative in future antimicrobial development

Abstract

The coral reef ecosystem on Pasumpahan Island holds significant ecological and economic value but is vulnerable to environmental pressures. This study aims to map shallow-water benthic habitats and to assess the accuracy of Sentinel-2 satellite image classification using the Lyzenga water-column correction method. The research involved radiometric correction, application of the water-column correction algorithm, and supervised classification using the Maximum Likelihood algorithm. Field validation was conducted using 30 ground-check points to assess accuracy using a confusion matrix. The analysis results indicate that the shallow waters of Pasumpahan Island are dominated by the substrate class, covering 15.75 Ha, while the coral reef class covers 7.78 Ha. The accuracy assessment yielded an Overall Accuracy of 83.3% and a Kappa Coefficient of 0.67, indicating substantial agreement and confirming the method's validity for spatial mapping. This study concludes that the Lyzenga method is effective in mapping benthic habitats with adequate accuracy, and the resulting map can serve as baseline data for area managers for conservation zoning.
