Abstract

This study was conducted to identify the secondary metabolite prile in the leaf extract of Lumnitzera racemosa, which has potential as a natural antibacterial agent. Leaf samples were collected from the mangrove area of Pecinta Alam Bahari (PAB), Dumai City, and extracted with 96% ethanol using a maceration method. Phytochemical tests were conducted qualitatively on seven groups of compounds, namely alkaloids, flavonoids, phenolics, saponins, tannins, triterpenoids, and steroids. Analysis revealed the presence of flavonoids, phenolics, and triterpenoids, while alkaloids, saponins, tannins, and steroids were not detected. The identified compounds have different antibacterial mechanisms but are effective in disrupting the structure and function of bacterial cells. These findings suggest the potential of L. racemosa leaf extract as a source of bioactive compounds for health and aquaculture applications.

Abstract

The Indo-Pacific region is the global center of marine biodiversity, home to more than 30% of the world's marine species. The order Decapoda, which comprises more than 17,000 species, plays significant ecological and economic roles in this region. This literature review aims to synthesize current knowledge on the genetic diversity and population structure of Decapoda in the Indo-Pacific and to identify the factors influencing these patterns. Molecular studies employing genetic markers such as mitochondrial DNA (mtDNA), microsatellites, and genomic sequencing indicate that Indo-Pacific Decapoda populations generally exhibit high haplotype diversity with relatively low nucleotide differentiation. Several factors, including larval dispersal capability, the duration of the planktonic phase, geographic and oceanographic barriers, and local adaptation to environmental conditions, shape population structure. Anthropogenic activities, particularly overexploitation, have led to declines in effective population size and genetic erosion in several commercially important species, such as Penaeus monodon and Scylla serrata. This review highlights the importance of integrating genetic data into sustainable fisheries management, including ecosystem-based stock assessment, periodic genetic monitoring, and the incorporation of genetic considerations in aquaculture and restocking programs to ensure the long-term sustainability of Decapoda populations in the Indo-Pacific region.

Abstract

Cilacap Regency is one of the regencies that serves as a disaster supermarket/laboratory. This means that Cilacap is at risk of disasters, including earthquakes, floods, landslides, and tsunamis. The objective is to assess community preparedness, specifically in the villages of Banjarsari and Nusawungu, and to prepare for earthquakes and tsunamis involving all components of society, both the government and the community itself, to achieve zero victims. This research was conducted from August to December 2023. Observations were made at the Banjarnegara Geophysical Station on Jalan Raya Banjarmangu Km. 12, Kalilunjar Village, Banjarmangu District, Banjarnegara Regency, Central Java. The method used in model the earthquake source mechanism was the P-wave first-impulse. The input to this system was waveform data from the InaTEWS network, which was entered via the internet using the Seedlink Protocol and then processed to enable automatic picking. The results were then used as input to determine the earthquake parameters and source mechanism in just a few seconds. Lightning observations are conducted using real-time recordings of atmospheric electrical events by the Lightning/2000 software, which are recorded in the format of atmospheric electrical event reports for one day, calculated from 00:00 to 24:00 local time. This is used to archive lightning event data for further processing in lightning mapping. The Tsunami Ready Community is a program to enhance community capacity in facing tsunami threats based on 12 indicators established by UNESCO-IOC. The hope is that the community will always be prepared and not be caught off guard in facing earthquake and tsunami threats

Abstract

Aquaculture intensification increases fish susceptibility to infectious diseases, prompting the search for natural alternatives to reduce dependence on synthetic chemicals. Bandotan leaves (Ageratum conyzoides L.) of the Asteraceae family contain secondary metabolites, including flavonoids, alkaloids, terpenoids, and saponins, with antibacterial, antioxidant, and immunomodulatory activities. This literature review aims to analyze the potential of bandotan leaves as a natural immunostimulant and antibacterial agent in aquaculture, focusing on their phytochemical content, mechanism of action, and safety. This study used a literature review method, conducting searches across national and international journal databases, university repositories, and research institute publications. The inclusion criteria included articles discussing the biological aspects, phytochemical content, antibacterial activity, immunomodulatory effects, physiological parameters, histology, and safety of bandotan leaves in the context of aquaculture. The results of the study showed that bandotan leaf extract effectively inhibited the growth of pathogenic bacteria in fish by disrupting cell membrane integrity and inhibiting bacterial enzymes. Its bioactive compounds enhance immune response, antioxidant activity, and reduce metabolic stress in fish. However, its application faces challenges in determining the optimal dosage, assessing histopathological effects, and managing potential respiratory distress at high concentrations. Further research is needed to optimize the formulation, understand the molecular mechanisms, and ensure the long-term safety of bandotan leaf use in sustainable fish farming systems.

Abstract

Human resources play a crucial role in realizing the company's established vision, mission, and objectives, and can significantly determine the company's actual achievements, given the available resources. Work discipline plays a crucial role in realizing the company's established vision, mission, and objectives, and can significantly determine the company's actual achievements given the available resources. The work discipline instilled by an organization or company in its employees greatly influences employees' dedication to their work. Employee performance is the tangible behavior of each individual regarding the results of their work for the company, so that each employee's work results differ from those of others. An individual's performance, whether good or poor, will significantly impact an organization's ability to achieve its goals. High performance fosters greater employee loyalty to the organization, increases motivation, and allows employees to enjoy the work they perform; however, it can sometimes leave individuals unable to escape the pressures of their work.  The research method employed uses questionnaires or interviews for data collection; thus, the data sources are referred to as respondents. Work discipline has a positive and significant influence on employee performance at the Regional Disaster Management Agency (BPBD) office in Pekanbaru City, as evidenced by the t-test, which indicates that the calculated t-value is greater than the critical t-value (7.038).
