Abstract

Currently, the implementation of the Halal assurance system in Indonesia is mandatory. A side from food, pharmaceutical, cosmetics, and medicines must all be halal certified. Natural products, particularly marine-based products, are an alternative choice for the cosmetics and pharmaceutical industry's raw materials. Enhalus acoroides are common along Indonesia's coasts and have the potential to be used as raw materials in halal cosmetics and pharmaceutical products. The purpose of this paper is to examine the potential of E. acoroides samples collected from various locations in Indonesia in terms of bioactive compounds and their applications. Secondary metabolites namely alkaloids, flavonoids, polyphenols, steroids, triterpenes, and tannins have been reported in E. acoroides extract from Indonesia, and they have the potential to be used as antibacterial, antiaging, antiviral, antitumor, and antioxidant in the pharmaceutical and cosmetic industries in Indonesia

Abstract

Background: Sea cucumbers (Holothuroidea) are key benthic organisms that contribute to coastal ecosystem stability through bioturbation, organic matter decomposition, and their role in marine food webs. However, despite their ecological and economic importance, information on the diversity and community structure of sea cucumbers in the waters of Batam City, remains limited. This study aimed to analyze the diversity of sea cucumbers in the waters of Sarang Island and the Nenek Strait, as a basis for evaluating ecological conditions and supporting sustainable marine resource management. Methodology: Sampling was conducted in the intertidal zone using the sweeping method during nighttime to accommodate the nocturnal activity of sea cucumbers, using two transects at each sampling station. Species identification was based on morphological and visual characteristics, while environmental parameters such as temperature, pH, salinity, dissolved oxygen, water transparency, and current velocity were measured in situ. Findings: Five sea cucumber species were identified, namely Stichopus herrmanni, Holothuria leucospilota, H.scabra, Bohadschia aegyptia, and H. fuscopunctata. Community structure was then analyzed using the Shannon–Wiener diversity index (H’), evenness index (E), and Simpson’s dominance index (C). At Sarang Island, 25 individuals representing five species were recorded, with Actinopyga mauritiana dominating 64% of the population, resulting in moderate diversity (H’ = 0.576), low evenness (E = 0.358), and high dominance (C = 0.453). In the Nenek Strait, 22 individuals from three species were identified, showing moderate diversity (H’ = 1.059), high evenness (E = 0.964), and low dominance (C = 0.360), actinopyga mauritiana dominated 64% of the population, likely due to its higher tolerance to local environmental conditions and its preference for sandy–muddy substrates commonly found in the study area, indicating a more balanced community structure. Contributions: These findings highlight spatial variation in sea cucumber communities related to habitat characteristics and ecological pressure, contributing baseline scientific data on the diversity and community structure of Holothuroidea in Batam coastal waters

Abstract

Background: This study examined the morphometric characteristics, length–weight relationship, and condition factor of scallops belonging to the family Pectinidae in the waters of Sarang Island and Mecan Island, Belakang Padang District, Batam City. This research is important because scientific information regarding the biological characteristics and population condition of scallops in this area is still limited, while exploitation by local fishermen continues to occur. Methodology: The study was conducted from August to October 2024 using a quantitative descriptive approach. Sampling was carried out through diving surveys at three fishing stations using a sweeping technique along transects covering an area of approximately 100 m² at depths ranging from 2–6 m. Morphometric measurements included shell length, shell width, shell thickness, dorsal width, and total body weight. The length–weight relationship was analyzed using logarithmic regression, while physiological condition was evaluated using the relative condition factor (Kn). Findings: A total of 88 individuals were collected.. Water quality parameters showed suitable environmental conditions with temperature ranging from 29–31 °C, salinity 30–32 ppt, dissolved oxygen 5.2–6.4 mg/L, and pH 7.6–8.1. The growth exponent (b = 2.5877) indicates a negative allometric growth pattern, where shell length increases faster than body weight. This pattern may reflect ecological adaptation and environmental conditions in the study area. Contributions: These findings provide baseline biological information for sustainable scallop resource management

Abstract

Background: The Manila clam Ruditapes philippinarum is an economically important marine bivalve and a key component of coastal ecosystems. Environmental factors such as sedimentation, salinity fluctuations, and human activities may influence its abundance, growth, and physiological condition. This study aimed to assess the abundance, morphometric characteristics, length–weight relationship, and condition factor of R. philippinarum in the waters surrounding Sarang Island, Batam Plot. Methodology: Sampling was conducted at three intertidal stations—Tempayang Island, Piring Island, and Layang Island—using purposive manual collection within 3 plot observation. Shell length, height, and thickness were measured using digital calipers, and total weight was recorded with a digital balance. Growth patterns were analyzed using log–log regression, while condition factors (K and WR) were used to evaluate physiological status. Findings: 87 individuals of R. philippinarum were recorded at Station 1, 118 at Station 2, and 117 at Station 3. The shell length of Ruditapes philippinarum ranged from 15.2 to 42.6 mm across all sampling stations. The length–weight relationship showed a weak correlation (r = 0.145) with a low coefficient of determination (R² = 0.21%) and a negative allometric growth pattern (b = −0.3419). The WR value (121.81) indicated generally good physiological condition. Water quality parameters were generally within tolerance limits; however, stations with higher total dissolved solids and lower water transparency indicated increased turbidity, which was associated with relatively smaller shell sizes of R. philippinarum compared to stations with better water clarity. Overall, variations in abundance and size among stations were influenced by environmental differences, while the R. philippinarum population remained relatively healthy. Contributions: These findings provide baseline ecological information that can support future monitoring and sustainable management strategies for R. philippinarum resources in intertidal coastal ecosystems

Abstract

The exploitation of sea cucumbers in Indonesia has reportedly increased by 66% in the last two decades. This figure is considered the upper limit for sustainable exploitation. The waters of Batam, Riau Islands, are known as one of sea cucumber producers. However, no current status report exists on Batam Island's diversity and abundance of sea cucumbers.  This study aimed to determine the diversity of species and the abundance of sea cucumbers found in Abang, Ngenang, Temoyong Island, and Riau Island. Sampling was carried out quantitatively by applying the quadratic transect method at the three locations. About three transect lines were placed at each station, drawn perpendicular from the coastline towards the sea with a length of 50 m. The distance between each transect line was 50 m, and a 5x5 m plot was placed on each. The results showed that there were six types of sea cucumbers, namely Stichopus nactivagus, Stichopus hermanni, Stichopus monotuberculatus, Holothuria scabra, Holothuria impatiens, and Holothuria leucospila. The species diversity in three locations ranged from 0.214 to 0.314. The abundance of species on Abang, Ngenang, and Temoyong Islands was in the range of 0.073 to 0.1 individual/m2, respectively. The low diversity and abundance indicate high environmental pressure on Batam, Riau Islands sea cucumber populations.

Abstract

Free radicals exert numerous detrimental impacts, necessitating the presence of antioxidants to mitigate these adverse consequences. Previous studies have documented the antioxidant activity of sea cucumber from the Holothuroidea family. However, the impact of extraction techniques on the antioxidant activity of sea cucumber extracts has not been well-studied. Thus, this study aims to examine collagen extracts’ antioxidant activity through two distinct processes: Soxhlet extraction and maceration. The extracted samples were concentrated using the freeze-drying method, followed by a phytochemical analysis, functional group identification via FTIR, and an antioxidant activity assessment using the DPPH method. The antioxidant activity is quantified by the IC50 value. The phytochemical analysis showed that the sea cucumber extract had alkaloids, phenolics, and saponins. The FTIR results indicated that the sea cucumber extract contained a functional carbonyl amide group, akin to that of peptide compounds. The IC50 value of sea cucumber extract obtained from maceration (10.558 ± 0.033) was compared to Soxhlet extraction (19.107 ± 0.041) µg/mL. The antioxidant activity of sea cucumber extract obtained from maceration was superior to that derived from the Soxhlet method.
