Abstract

Ekosistem mangrove memiliki peran penting dalam mendukung produktivitas tambak melalui produksi serasah sebagai sumber bahan organik alami. Penelitian ini bertujuan untuk menganalisis produktivitas serasah Avicennia sp. pada sistem tambak silvofishery di Blanakan, Subang, Jawa Barat. Penelitian dilaksanakan pada bulan April–Mei dan Agustus 2018 dengan metode pengambilan sampel menggunakan litter trap pada tiga lokasi tambak. Serasah yang tertampung dikeringkan dan ditimbang untuk menghitung produktivitas dalam satuan g/m²/hari. Hasil penelitian menunjukkan bahwa produktivitas dengan nilai tertinggi produktivitas serasah berkisar antara 1,70–2,15 g/m²/hari, dengan nilai tertinggi pada Tambak 1 dan terendah pada Tambak 3. Secara statistik, tidak terdapat perbedaan yang signifikan antar tambak (p>0,05). Selain itu, hasil uji korelasi Pearson menunjukkan bahwa parameter lingkungan yang diukur (suhu, salinitas, pH, dan DO) tidak memiliki hubungan yang signifikan dengan produktivitas serasah (p>0,05). Meskipun demikian, secara deskriptif terlihat adanya variasi produktivitas antar lokasi dan waktu pengambilan sampel, yang mengindikasikan adanya dinamika produksi serasah pada masing-masing tambak. Hasil ini menunjukkan bahwa variasi produktivitas serasah kemungkinan dipengaruhi oleh faktor lain di luar parameter yang diukur, seperti kondisi vegetasi dan karakteristik lokal tambak.

Abstract

Lombok Island is a major center for the cultivation of the Pinctada maxima pearl oyster, a species renowned for producing high-value South Sea pearls. The sustainability of pearl farming in this region relies not only on favorable water quality but also on the effective implementation of Ecosystem-Based Management (EBM), which integrates the roles of government agencies, industry stakeholders, and local communities in safeguarding marine ecosystem integrity. This study applied an EBM approach to assess environmental suitability for sustainable pearl cultivation in West Lombok. Field data were collected from three cultivation sites between January and February 2025 through in situ measurements and laboratory analyses of key physicochemical parameters. The results show that pH (7.69), dissolved oxygen (6.38 mg/L), salinity (29.69‰), ammonia (0.037 mg/L), and TSS (0.065 mg/L) were within optimal ranges and complied with marine water quality standards. However, water temperatures reached up to 32.8°C at several sites, exceeding the optimal thermal range for Pinctada maxima and posing risks of physiological stress and reduced pearl quality. To mitigate temperature-related stress, flotation-controlled longline technology can be employed to adjust oyster depth in accordance with thermocline layers that provide more stable thermal and salinity conditions. The integration of such adaptive technologies—combined with active, multi-stakeholder collaboration under the EBM framework—constitutes a critical foundation for maintaining ecosystem stability and ensuring the long-term socioeconomic sustainability of the pearl farming sector in West Lombok.

Abstract. Takarina ND. 2020. Remobilization of zinc in sediments by mangrove and its associated species in Blanakan River, West Java, Indonesia. Biodiversitas 21: 1743-1748. The biodiversity of mangrove and associated species have contribution to remove contaminants from aquatic environment, for example, river. This work aims to study the effects of mangrove and associated species in absorbing zinc (Zn) from water and sediment and remobilizing it into stems. The work was conducted by sampling mangroves, associated species, sediment and water along 9 stations in riparian of Blanakan River, West Java. The stems of mangrove and associated species, water and sediments were analyzed for Zn content using AAS. The biodiversity was evaluated using Shannon-Wiener index (H’). The bioremobilization potential was calculated using Bioconcentration Factor (BCF). There were 3 true mangrove species (i.e. Rhizophora mucronata, Avicennia marina, and Sonneratia caseolaris) and 3 mangrove associate species (i.e. Colocasia esculenta, Ipomoea aquatica, and Wedelia biflora). The H’ was ranging from 0.5 to 0.7. We found that the riparian with high species richness and biodiversity has less Zn contents both in water and sediments, while the riparian that has low species diversity has high Zn in water and sediments. All the mangrove and associated species have stored Zn in their stems with the most effective species in remobilizing Zn from water and sediment were C. esculenta, S. caseolaris, and R. mucronata. The contamination of Zn in aquatic ecosystem can be managed and reduced by increasing mangrove and associated species diversity and planting species that effective in remobilization of contaminants from environment.

Abstract. Takarina ND, Utomo SW, Susanti L, Rochman NT, Cahyadi D, Junaedi H, Saputra HKH, Saputra RN. 2020. Phytoplankton biodiversity trends in nanobubble aerated shrimp farming at Probolinggo coast, East Java, Indonesia. Biodiversitas 21: 5906-5914. Phytoplankton is known as an important factor in shrimp farming and its abundance and biodiversity are varied. Nanobubble aeration is one of current aquaculture treatments used in brackish water shrimp ponds. This study aimed to investigate phytoplankton biodiversity trends in nanobubble and control ponds within 21-day observation period. The measured water quality parameters were dissolved oxygen (DO), NH4+, NO2-, pH, salinity, temperature, and water clarity. Data analysis includes calculation of abundance and biodiversity using Shannon-Wiener (H’) index and correlation using Principal Component Analysis (PCA). A total of 11 phytoplankton species from 5 divisions was recorded. The results show increasing trends in phytoplankton abundance, species, and H’. In pond with nanobubble, H’ increased from 0.322 (95%CI: 0.074-0.718) to 0.561 (95%CI: 0.208-0.916) after 21 days, while in control pond, H’ increased from 0.199 (95%CI: 0.000-0.520) to 0.326 (95%CI: 0.000-0.683). In the nanobubble pond, species showing increasing trend in abundance were Pleurosigma sp., Nitzchia sp., Anabaena sp., Oscillatoria sp., and Microcystis sp. Whereas, species showing a declining abundance trend were Chlorella sp. and Amphora sp. According to PCA, phytoplankton abundance was positively correlated with pH, water clarity, DO, NO2-, and negative correlation with salinity, temperature, and NH4+.

Abstract. Takarina ND, Sinaga IL, Kultsum TR. 2021. Riparian plant diversity in relation to artisanal mining sites in Cikidang River, Banten, Indonesia. Biodiversitas 22: 401-407. Artisanal mining usually occurs in gold mining activities near the river banks and consequently, this will affect the downstream ecosystem include riparian habitat and its plant diversity. Here, this study aimed to assess the effects of artisanal mining sites on the riparian plant diversity in Cikidang River, Lebak District, Banten Province, Indonesia. The study was conducted by placing 10 sampling stations along 4 km of Cikidang River with width of 20 m. Riparian plant species were collected and identified from 10 m x 10 m sampling plots in each station. Plant diversity was assessed using Shannon-Wiener, Simpson, Margalef, and Pielou indices. There were in total 18 families and 42 plant species have been identified. Compositae and Poaceae were plant families that common here. Ageratum conyzoides was the most common species followed by Impatiens platypetala, Cibadium surinamense, Wollastonia biflora, Calliandra calothyrsus, and Pityrogramma calomelanos. Shannon-Wiener diversity index was in the range of 1.040-1.561. There was a positive correlation between riparian diversity with the distance to mining sites with decreasing diversity trends toward artisanal mining sites. Riparian habitats located far (> 1 km) from the mining sites have more species. While species observed in riparian habitats near (0.3-1 km) the mining sites were accounted only for 26.1% of total species found. To conclude, the presence of artisanal mining sites can affect the nearby riparian plant diversity.

Abstract. Pin TG, Supriatna J, Takarina ND, Tambunan RP. 2021. Mangrove diversity and suitability assessments for ecotourism in Cimalaya Wetan Coast, Karawang District, Indonesia. Biodiversitas 22: 803-810. Mangrove forest has been a popular ecotourism destination recently. One of the methods to assess the mangrove potential for ecotourism is by using Tourism Suitability Index (TSI). This study was aimed to assess the ecotourism potentials of mangrove forest sizing of 56.43 hectares in Cilamaya Wetan Sub-district, Karawang District, West Java Province, Indonesia using the TSI method. To assess the mangrove variables, 10 sampling stations have been selected across the coast. In each station, 10 sample plots sizing of 10 m x 10 m have been established. The TSI was measured based on mangrove variables including species diversity, density, and thickness. We recorded six mangrove plant species belonging to three plant families. Avicennia alba, Bruguiera gymnorrhiza and Rhizophora stylosa, were common species found along the coast. Shannon-Wiener index (H’) showed that the west and east parts of Cimalaya Wetan had high mangrove diversity compared to the central part. The TSI analysis showed that the most suitable areas of mangrove forests for ecotourism were 32.18 hectares (57.11% of the total area), mainly located in the east part of the coast. Moreover, the moderate and least suitable areas were 19.12 hectares (33.94%) and 5.03 hectares (8.93%), respectively, and located in the central part of the coast.

Abstract. Takarina ND, Nasution AK, Thoha H. 2021. The presence and abundance of harmful dinoflagellate algae related to water quality in Jakarta Bay, Indonesia. Biodiversitas 22: 2909-2917. Dinoflagellate is a single-celled organism that commonly occurs in large numbers in marine environment. When environment changes, harmful dinoflagellate algae often emerge as a response to change in water quality. Jakarta Bay, Indonesia is the meeting point of 13 rivers that carry anthropogenic effluents, not only from agriculture and human settlements, but also industrial activities with some initial evidence showed the increasing growth of harmful algae population and decreasing water quality. This study aims to assess the correlations between dinoflagellate abundance and water quality parameters (i.e., dissolved oxygen, pH, salinity, temperature, and turbidity) in Jakarta Bay. Dinoflagellates were sampled in July 2020 at four river mouths, namely Ancol, Muara Baru, Muara Angke, and Muara Karang, each with three replications. Results showed that five dinoflagellates categorized as harmful were recorded. The following order of dinoflagellates based on abundance was Noctiluca > Ceratium > Gonyaulax > Gymnodinium > Dinophysis. Dinoflagellate abundance ranges were as low as 353,857 cells/m3 for Dinophysis and as high as 85,279,547 cells/m3 for Noctiluca. In terms of location, Muara Baru had the highest dinoflagellate abundance. There were correlations between dinoflagellate abundance with water quality. The dinoflagellate abundance was positively correlated with DO (Gymnodinium 0.5152; Dinophysis 0.5262; Gonyaulax 0.3701; Noctiluca 0.0429; Ceratium 0.4168) and temperature (Gymonodium 0.3894; Ceratium 0.3627; Gonyaulax 0.3428;Dinophysis 0.2536) but negatively correlated with pH (Ceratium-0.5558; Dinophysis-0.4868; Gymonodinium-0.4284; Noctiluca-0.4201; Gonyaulax-0.3881), turbidity (Dinophysis-0.2336; Gonyaulax-0.0105; Noctiluca-0.1164; Ceratium-0.0896), salinity (Gymnodinium-0.2176; Dinophysis-0.0888; Ceratium-0.0434).

Abstract. Suwanto A, Takarina ND, Koestoer RH, Frimawaty E. 2021. Diversity, biomass, covers, and NDVI of restored mangrove forests in Karawang and Subang Coasts, West Java, Indonesia. Biodiversitas 22: 4115-4122. Indonesia has been recognized as the country with greatest diversity of mangrove species with significant amount of carbon sink and biomass. In few recent decades, mangrove forests have been deforested significantly. One of the solutions to deal with mangrove deforestation is through restoration. West Java north coasts are one of the areas that have experienced deforestation, however and mangrove restorations have been conducted mainly in Karawang and Subang coasts. Correspondingly this research aims to assess the mangrove diversity using index and biomass resulted from restoration program in those coasts. To assess the mangrove diversity in each coast on June 2021, 6 sampling stations containing 3 replicated sample plots of size 10 m × 10 m were located. In total 8 species with 1549 trees were been sampled. In Subang the order of mangrove species from common to less-common species were Avicennia marina > Rhizophora mucronata > Sonneratia caseolaris > Acanthus ilicifolius > Bruguiera gymnorhiza. While the order in Karawang was Avicennia marina > Rhizophora mucronata > Rhizophora apiculata > Sonneratia caseolaris > Bruguiera gymnorhiza. The mangrove diversity (H)’ was significantly different (p = 0.000, F = 2.216) with diversity in Subang Coast (average H' = 1.326, 95% CI: 1.15-1.5) was higher than in Karawang (average H’ = 1.063, 95%CI: 0.934-1.2). Estimated restored mangrove covers in Subang were 3.612 km2 and 0.46 km2 in Karawang. R. mucronata was mangrove species that has the highest biomass with the value of 1337.91 mg ha-1 and the lowest was A. marina with value of 14.3 mg ha-1. The results suggest that restoration areas in Subang and Karawang have significant contributions to maintain mangrove diversity, biomass, and covers.

Abstract. Ewaldo K, Karuniasa M, Takarina ND. 2023. Carrying capacity of mangrove ecotourism area in Pantai Indah Kapuk, North Jakarta, Indonesia. Biodiversitas 24: 5809-5820. Mangroves are crucial in providing various ecological and economic benefits to local communities. This study focuses on the economic aspect of mangroves by analyzing their potential as a tourist attraction in the Mangrove Ecotourism, Pantai Indah Kapuk (PIK). The objective of this study is to analyze the carrying capacity of the mangroves as a tourist attraction to ensure sustainable tourism development. The study was conducted in the Mangrove Ecotourism area, Pantai Indah Kapuk, from January to March 2023, utilizing a quantitative approach. The carrying capacity of the mangrove ecosystem was assessed using the Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity (ECC) methods. The calculated values for PCC, RCC, and ECC were 107, 16, and 313 visitors/day, respectively. The analysis revealed that the number of visitors at the PIK Mangrove Ecotourism in 2022 had exceeded the PCC and RCC limits, indicating potential ecological impacts. However, the number of visitors had remained within the ECC limits, suggesting that with proper management, the site could accommodate the current visitor levels sustainably. To achieve long-term sustainability, several initiatives are recommended, such as creating zoning in tourist areas to distribute visitor pressure, increasing the number of field officers to monitor the site, and implementing an online ordering system to manage visitor flow efficiently. The findings of this study contribute to the understanding of the carrying capacity concept in ecotourism and provide valuable insights for the management and conservation of mangrove ecosystems as tourist attractions.

Abstract. Adidharma MA, Supriatna, Takarina ND. 2023. The impact of nickel mining on vegetation index in Molawe Sub-district, North Konawe District, Southeast Sulawesi, Indonesia. Biodiversitas 24: 4581-4588. Nickel mining activities in Molawe Sub-district, North Konawe District, Southeast Sulawesi, Indonesia have modified the land cover structure over time due to increased mining exploitation zones. This study intends to assess changes in land cover in the Molawe Sub-district, particularly around mining regions. The NDVI index was applied to Landsat 7 ETM+ satellite imagery data in 2001 to identify land cover conditions before mining activities, then to Landsat 8 OLI imagery data in 2015 and 2020 to identify land cover after mining activities. These data are then used to compute annual changes in the extent of each land cover. The NDVI classification produces four land cover types: non-vegetation, open soil, sparse vegetation, and moderate vegetation. The study shows that non-vegetation and open ground cover types experienced a significant increase in area from 2001 to 2015 and from 2015 to 2020. Meanwhile, sparse vegetation forest cover experienced a reduction in area from 2001 to 2015 and 2015 to 2020. In contrast to sparse vegetation, the moderate vegetation cover is experiencing a minor increase in area. Based on these results, relevant policymakers need to formulate policies to mitigate environmental impacts that may arise in the future.
