Abstract

Macrobenthos is a biological resource of water that lives at the bottom of the waters with characteristics that have a high level of sensitivity to changes in environmental quality as a bioindicator of pollution and environmental quality. The purpose of this study was to determine the diversity of macrobenthos as an indicator of pollution in the coastal waters of Kotania. Descriptive research with a random sampling method with a square transect. Data collection through observation of macrobenthos populations. The results of the macrobenthos diversity study obtained were in the Gastropoda class with six families namely Cerithiidae, Neritidae, Mitridae, Nassariidae, Littorinidae and Potamididae consisting of nine species namely Cerithium coniculatum, Nerita polita, Nerita patula, Nerita alveolus, Mitra pica, Nasarius pullus, Litorina scabra, Terebralia palustris and Telescopium telescopium, which shows its role as a potential bioindicator associated with dissolved oxygen, water clarity, and higher nutrient levels, indicating its suitability as an indicator of mild to moderate pollution conditions. These findings indicate that macrozoobenthos communities respond sensitively to land use changes and can effectively indicate variations in coastal water quality

Abstract

Cherax quadricarinatus is a high-value freshwater crustacean, yet live transportation remains a major challenge as it may reduce survival and induce physiological stress. This study aimed to evaluate the use of rice straw, coconut husk, and banana stem as organic packing media on induction time, sedation time, survival, and molting percentage of C. quadricarinatus juveniles. A completely randomized design was applied with three treatments (JP, SK, BP), each in triplicate, using a total of 90 juveniles (4–6 cm). Data were analyzed using ANOVA followed by the LSD test at a 95% confidence level. Results indicated that transport media influenced lobster physiological responses. Coconut husk resulted in relatively longer induction and sedation times, whereas banana stem yielded the highest survival rate and molting percentage. Although statistical differences were not significant, data trends confirmed the superiority of banana stem in maintaining moisture and physiological stability during transportation. This study recommends banana stem as an eco-friendly and effective organic medium for live transport of C. quadricarinatus juveniles. Keywords: Cherax quadricarinatus; dry transport; organic medium; survival Abstrak.  Cherax quadricarinatus merupakan spesies krustasea air tawar bernilai ekonomi tinggi, namun transportasi hidup masih menjadi kendala utama karena dapat menurunkan kelangsungan hidup serta memicu stres fisiologis. Penelitian ini bertujuan mengevaluasi pemanfaatan jerami padi, sabut kelapa, serta batang pisang sebagai media organik transportasi terhadap waktu induksi, waktu sedatif, survival, serta persentase molting benih C. quadricarinatus. Rancangan acak lengkap digunakan dengan tiga perlakuan media (JP, SK, BP) masing-masing tiga ulangan, menggunakan total 90 ekor benih berukuran 4–6 cm. Data dianalisis menggunakan ANOVA serta uji BNT pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa media berpengaruh terhadap kondisi fisiologis lobster. Sabut kelapa menghasilkan waktu induksi dan sedatif relatif lebih lama, sedangkan batang pisang menunjukkan survival tertinggi serta persentase molting lebih besar dibandingkan dengan perlakuan lain. Meskipun perbedaan statistik tidak signifikan, tren data menegaskan bahwa batang pisang lebih efektif mempertahankan kelembapan serta stabilitas fisiologis selama transportasi. Penelitian ini merekomendasikan batang pisang sebagai media transportasi organik ramah lingkungan untuk mendukung distribusi benih C. quadricarinatus.
