“…Hamuna et al (2018) also added that the level of water brightness significantly affects the photosynthesis process and the growth rate of marine biota. Patty et al (2020) that the results of measurements of water brightness in Tumbak-Bantenan waters, Southeast Minahasa, show a value of 4.5-31.5 meters with an average value of 19.0 ± 9.43 meters. Meanwhile, Edrus & Setyawan (2013) reported that the brightness of local waters varies from 1.5 to 15 meters on the island of Belitung.…”

Background: Mantis shrimp is one of the favorite shrimp caught by fishermen around the estuary waters of Berombang River, Labuhanbatu Regency. This study aimed to determine the condition factors and growth patterns of mantis shrimp population. Method: Three station points were determined using a purposive random sampling method. The sampling of Harpiosquilla raphidea was carried out using trawl nets. The data analysis provided information on growth patterns and condition factors. Result: The results showed that the growth patterns of male H. raphidea belonged to the positive b> 3 allometric category, where weight growth was faster than carapace growth. Moreover, the growth patterns of female H. raphidea belonged to the negative b<3 allometric category, where the carapace growth was faster than body weight growth. The value of Fulton (K) condition factors for male H. raphidea ranged from 3.54 to 13.18, and for females, it ranged from 15.28 to 22.09. The value of correlation analysis of Physic-chemical parameters, water temperature (0.935) and DO (0.832) showed the high category correlation test results. Conclusion: This result showed that from November 2021 to January 2022, the condition of H. raphidea population around the estuary waters of Berombang River was known and predicted to be in the adult stage

“…The variation coefficient value >100% indicates the turbidity value between stations is very varied. From the results of turbidity measurements, it can be seen that two stations have very high values >5 NTU, namely, station 13 and station 15, different from other stations <1 NTU [13].…”

INTRODUCTION: The coastal area of Makassar city is a vulnerable area to various pollutants, most of which are generated by anthropogenic activities, such as home industry products, gold shop waste products, and household waste, starting from the coastal area in Barombong to the coastal villages in the Ujung Tanah subdistrict, with the highest level of mercury (Hg) concentration in the coastal area. Another source of potential Hg pollution in this area can be due to community activities at the fish landing base (PPI, Paotere). AIMS: The aims of this research were to analyze the Hg content in surface water collected from coastal areas of Makassar City and to analyze the target hazard risk effect due to the excessive exposure of water from the recognized as ecologically contaminated area. MATERIALS AND METHODS: This research applied an observational analytic design of cross-sectional studies. Direct measurement and laboratory sample analyses were conducted as well as a questionnaire was applied to obtain relevant, precise, and accurate data. Respondents’ characteristics related to education, habit, lifestyle, occupational smoking habits, and dietary were requested by the administered household interview questionnaire. Assay of the laboratory to analyze the magnitude of Hg in surface water was conducted. Respondents with volunteered based selected using stratified random sampling methods. RESULTS: Results of the analysis of Hg distribution in surface water used kriging interpolation method showed that the highest concentration of Hg was in stations (22 and 23) around Area of Anjungan Losari Beach and Area of Anjungan Mandar Losari with 1.0013 and 1.0012 mg/l, respectively. While the lowest were in station 2 with 0.0011 and in station 26 Pelindo Jetti area with 0.0013 mg/l, respectively. Ecological Risk assessment indicated that the areas with the highest risk of ecology were such as Near Dermaga Kayu Bangkoa with 9.8, the Tourism area of Karaeng Batjo Tomb 9.7, and Tanjung Bayang beach with risk ecology 9.1 units, respectively. Furthermore, the magnitude of Target Hazard Quotient (THQ) values were 0.0093 in station 1 in Tourism area of Karaeng Batjo Tomb and 0.0089 units in station 24 of Port of Sukarno Hatta, respectively. CONCLUSIONS: To conclude, Hg levels of contamination in water are still be tolerated in the current; however, its accumulate that potentially harmful in the near future. Ecological risk value was more than one that indicates at risks, although the THQ values are still below than the one that indicates safe.

“…Hal ini diduga dipengaruhi oleh cuaca pada saat pengukuran, cuaca pada bulan Februari sangat cerah sehingga intensitas cahaya matahari yang mengenai substrat menyerap kelembapan tanah sehingga suhu substrat menjadi tinggi. Hal ini sesuai dengan pernyataan Patty et al (2020) bahwa nilai suhu bervariasi dipengaruhi terutama oleh kondisi atmosfir, cuaca dan intensitas cahaya matahari.…”

Sumber daya pesisir Perairan Nambo di Kota Kendari meliputi ekosistem mangrove dan lamun yang memberikan manfaat ekologi bagi kehidupan organisme bentik dan organisme lainnya. Salah satu organisme bentik yang dimanfaatkan oleh masyarakat setempat adalah kerang lentera. Tujuan penelitian ini untuk mengetahui preferensi habitat kerang lentera di Perairan Nambo. Pengambilan sampel menggunakan metode acak sistematis dengan interval waktu dua kali sebulan. Data kepadatan, pola distribusi dan distribusi ukuran dianalisis. Preferensi habitat kerang lentera dianalisis dengan Coresponden Analysis (CA) dan Principle Componen Analysis (PCA) untuk mengetahui karakteristik parameter perairan melalui program XLSTAT versi 2014. Hasil analisis menunjukkan nilai kepadatan kerang lentera yaitu 1,06–10,44 ind/m2. Indeks pola distribusi menunjukkan kerang lentera mempunyai penyebaran acak dan seragam. Sebaran ukuran panjang total (panjang cangkang dan pedikel) kerang lentera dikelompokkan dalam 10 kelas ukuran, dimana ukuran yang mendominasi adalah 77–102 mm. Preferensi habitat kerang lentera dikarakteristikkan oleh tekstur substrat pasir sedang dan berlumpur pada daerah ekosistem mangrove.
