Abstract

The Sungsang area in the Musi River estuary is an important fishing ground that is potentially exposed to zinc (Zn) contamination due to intensive anthropogenic activities. This study aimed to analyze Zn accumulation in mantis shrimp (Harpiosquilla raphidea) and to evaluate its consumption safety. Samples were collected from local collectors and analyzed using flame atomic absorption spectrophotometry in accordance with SNI 2354-13:2014. The results showed that Zn concentrations ranged from 20.24 to 21.27 mg/kg, with an average of 20.70 mg/kg, remaining below the maximum permissible limit established by Dirjen POM (1989). Risk assessment based on estimated intake indicated that Zn exposure from mantis shrimp consumption is within safe limits for humans. Overall, these findings confirm that mantis shrimp from Sungsang are safe for consumption with respect to Zn contamination. This study provides scientific evidence for food safety assessment and underscores the need for continuous monitoring of heavy metal contamination to support sustainable coastal resource management.

Abstract

Despite the ecological and economic significance of coral reefs, quantitative data on how water quality parameters regulate zooxanthellae density in anthropogenically impacted tropical reefs remain limited. This study investigated the influence of water quality parameters on zooxanthellae density in branching corals at Pahawang Island, Lampung, Indonesia, across four stations representing different levels of human disturbance: dock area (Station 1), floating net cages area (Station 2), recreational area (Station 3), and a relatively pristine area (Station 4). Coral fragments were collected by SCUBA diving at 2–5 m depth, and zooxanthellae were extracted by homogenization followed by centrifugation, with cell density quantified using a hemocytometer under light microscopy. Physical and chemical water quality parameters were measured in situ using a CTD profiler, while nutrient concentrations were analyzed according to SNI protocols. Zooxanthellae density ranged from 16,822 to 22,227 cells/cm², indicating a healthy symbiotic status across all stations. Principal Component Analysis (PCA) identified dissolved oxygen (5.5–6.4 mg/L), depth (2.20–4.10 m), and water clarity (2.0–3.0 m) as the primary environmental drivers of zooxanthellae density variation, while temperature, pH, and salinity remained stable and within coral-suitable ranges. Hydrodynamic conditions and oxygen availability, rather than nutrient enrichment, appear to be the dominant regulators of zooxanthellae density at this site. These findings highlight the need for site-specific management strategies that prioritize maintaining dissolved oxygen levels and water circulation, and provide a scientific basis for developing zoning policies in coral ecotourism areas of Pahawang Island to ensure long-term reef ecosystem health.

Abstract

Penelitian ini mengkaji distribusi vertikal dan temporal zooplankton di estuari tropis dangkal menggunakan intensitas gema Acoustic Doppler Current Profiler (ADCP) 492 kHz yang dikonversi menjadi Mean Volume Backscattering Strength (MVBS), divalidasi dengan data zooplankton in situ. ADCP dipasang di dasar perairan selama 17 jam (03:00–20:09 WIB) pada 15 Oktober 2025 di Estuari Sungai Musi, dilengkapi profil CTD per jam dan sampel jaring zooplankton pada tiga lapisan kedalaman. Sebanyak 21 taksa dari 5 filum dan 8 kelas teridentifikasi, dengan Copepoda dominan (56–78%). MVBS berkisar −211 hingga −3 dB (median −153 dB); 332 titik data pada rentang −100 hingga −60 dB diinterpretasikan sebagai hamburan biologis. Lapisan hamburan persisten terdeteksi pada kedalaman 6,5–9 m dengan puncak di 9 m (MVBS ≈ −76 dB) dan intensifikasi pada sore hari, bertepatan dengan kenaikan kelimpahan (2.500–4.000 ind m⁻³) dan keanekaragaman sedang (H' = 1,32–1,74) pukul 18:00–20:00. Korelasi Spearman menunjukkan hubungan positif moderate antara MVBS dan log₁₀ kelimpahan (ρ ≈ 0,57; p < 0,05), bergantung pada lapisan kedalaman. Temuan ini menegaskan hambur balik ADCP terkoreksi hidrografi efektif sebagai proksi distribusi vertikal dan dinamika sub-harian zooplankton, meski sebagai estimator kuantitatif kelimpahan masih dibatasi komposisi komunitas, kedalaman kolom air, dan noise latar estuari.
