| Abstrak (Bhs. Indonesia) | Makrozoobentos merupakan salah satu bioindikator kualitas lingkungan yang keberadaanya dipengaruhi oleh karakteristik sedimen dan kandungan bahan organik. Penelitian ini bertujuan untuk mengetahui struktur komunitas makrozoobentos, kandungan bahan organik, tekstur sedimen, serta hubungan kelimpahan makrozoobentos berdasarkan kandungan bahan organik dan tekstur sedimen di kawasan mangrove Laguna Lembupurwo. Penelitian ini dilakukan dengan metode random sampling serta dianalisis dengan metode deskriptif dan statistik. Hasil penelitian menunjukkan bahwa makrozoobentos ditemukan sebanyak 18 spesies dengan jumlah total 488 individu. Kelimpahan makrozoobentos berkisar antara 127- 193 ind/m², indeks keanekaragaman (H') berkisar antara 0,18-0,963 tergolong kategori rendah, indeks keseragaman (E) berkisar antara 0,27-0,62 tergolong kategori tinggi-rendah, dan indeks dominansi (C) berkisar antara 0,47- 0,91 tergolong kategori tinggi-rendah. Kandungan bahan organik tergolong kategori sedang-tinggi dengan persentase rata-rata 13,41- 21,76%. Tekstur sedimen di dominansi oleh tekstur lumpur dengan persentase rata-rata berkisar antara 59-68%. Berdasarkan hasil analisis korelasi menunjukkan bahwa hanya tekstur lumpur yang memiliki hubungan dengan kelimpahan makrozoobentos, dengan nilai r = 0,221 yang tergolong dalam hubungan positif sangat lemah. Kelimpahan makrozoobentos di Laguna Lembupurwo mencerminkan kondisi habitat yang relatif kurang stabil serta kandungan bahan organik dan tekstur sedimen yang belum menunjukkan pengaruh nyata terhadap kelimpahan makrozoobentos. |

| Abtrak (Bhs. Inggris) | Macrozoobenthos are one of the bioindicators of environmental quality, whose presence is influenced by sediment characteristics and organic matter content. This study aimed to determine the community structure of macrozoobenthos, organic matter content, sediment texture, and the relationship between macrozoobenthos abundance and organic matter content and sediment texture in the mangrove area of Lembupurwo Lagoon. The study was conducted using a random sampling method and analyzed using descriptive and statistical methods. The results showed that 18 macrozoobenthos species were identified, with a total of 488 individuals. Macrozoobenthos abundance ranged from 127–193 ind/m², the species diversity index (H') ranged from 0.18–0.963 and was categorized as low, the evenness index (E) ranged from 0.27–0.62 and was categorized as high to low, and the dominance index (C) ranged from 0.47–0.91 and was categorized as high to low. Organic matter content was categorized as moderate to high, with an average percentage ranging from 13.41–21.76%. Sediment texture was dominated by mud, with an average percentage ranging from 59–68%. Based on the correlation analysis, only mud texture showed a relationship with macrozoobenthos abundance, with a correlation coefficient of r = 0.221, indicating a very weak positive relationship. The abundance of macrozoobenthos in Lembupurwo Lagoon reflects relatively unstable habitat conditions, while organic matter content and sediment texture did not show a significant influence on macrozoobenthos abundance. |
