Abstract

Mangrove ecosystem has important role as source of nutrient particularly nitrogen in coastal area. Nitrogen (N) is alimiting factor in marine and coastal area. The aim of this research was to study benthic fluxes and potency ofbacterial activity in sediment of mangroves area, related to nitrogen cycle. This research was conducted in floodedmangroves area in Pulau Dua. The sediment and overlying water was sampled using sediment core sampler.Experimental treatment for flux analysis and sediment-slurry were conducted in three hours. Nutrient of NH3-N,NO2-N, and NO3-N and abundance of nitrifier, denitrifier, DNRA, and ammonifier were analyzed. The resultsshowed that the abundance of anaerobic bacteria was higher than aerobic bacteria. The dominance of bacterialgroups found in sediment was ammonification bacteria. The highest nutrient concentration in sediment was NH3-N. Benthic fluxes value showed higher NH3-N tends to release from the sediment to water than NO2-N and NO3-N. Generally, mangrove sediment in Pulau Dua has higher potency ofbacterial activity (Vmax and Km) in NO3reduction by anaerobic bacteria than NH3 oxidation by aerobic bacteria.Keywords: bacteria, benthic fluxes, mangrove, potency of bacterial activity, sediment

Abstract

Intensification of shrimp farming has led to problems of water quality and development of pathogenic bacteria. The excess feed and fecal deposited in the bottom of the pond undergo ammonification and result in excess of ammonia formation in pond water and sediment. The purposes of this research was to investigate the impact nitrifying bacteria application on the controlling of pathogenic Vibrio sp. bacteria and toxic nitrogen gasses. Twelve (12) transparent glass bottles (effective volume of 3 L) were used in this research. Tested probiotic was purchased in free market and producer claims to contain Nitrosomonas sp., Nitrosococcus sp., Nitrobacter sp., Bacillus sp., Aerobacter sp., and Pseudomonas sp. The tested media was sea water containing Vibrio sp., TAN, NO2 and NO3 of 54.07 ± 2.93 mg/L; 6.33 ± 0.17 mg/L; 2.43 ± 0.04 mg/L; and 0.46 ± 0.01 mg/L respectively. The treatment of probiotic was 0 mg/L as a control; 0.1 mg/L; 0.2 mg/L; and 0.4 mg/L with 3 replications. In regard to concentration of Vibrio sp., NH3 and NO2 gasses, treatment doses of 0.1 mg/L (A) resulted a save level within 4 days after treatment, but to more secure in the practical work for shrimp farm, the doses of 0.2 mg/L (B) is suggested.

Abstract

Waduk Jatigede merupakan perairan daratan tergenang yang terbentuk dari pembendungan sungai Cimanuk. Waduk Jatigede, sebagaimana waduk umunnya, secara horizontal terbagi atas tiga wilayah, yaitu riverin, transisi, dan lakustrin. Perbedaan karakteristik setiap zona juga berdampak pada komposisi dan komunitas fitoplankton, status trofik, dan kandungan karbon. Penelitian ini bertujuan untuk mengalkulasi seberapa besar kandungan karbon pada fitoplankton di perairan Waduk Jatigede pada setiap zona dengan komposisi dan komunitas fitoplankton pada status trofik tertentu. Stasiun penelitian dipilih menggunakan purposive sampling dengan pemilihan stasiun berdasarkan zona dalam waduk, yaitu riverin, transisi, dan lakustrin. Analisis status trofik dan kandungan karbon digunakan untuk mengetahui kondisi dan keberadaan karbon di Waduk Jatiged. Status trofik Waduk Jatigede berdasarkan Indeks Nygaard dan TSI (Tropic State Index) dikategorikan ke dalam tingkat kesuburan eutrofik. Jenis-jenis dari Kelas Cyanophyceae memiliki kelimpahan tertinggi, tetapi kandungan karbon tertinggi berada di kelas Dinophyceae. Zonasi riverin, transisi, dan lakustrin memiliki status kesuburan yang sama, tetapi memiliki komposisi dan komunitas fitoplankton yang berbeda. Berdasarkan hasil penelitian, diperoleh kandungan karbon fitoplankton relatif tinggi di zona riverin dan lakustrin, dan rendah di zona transisi.

Abstract

Pencemaran sungai perlu diupayakan solusinya mengingat dampaknya terhadap kehidupan biota perairan dan sosial ekonomi masyarakat. Salah satu sumber pencemaran sungai berasal dari sampah organik rumah tangga yang banyak dibuang ke lingkungan perairan. Sampah tersebut dapat meningkatkan kandungan bahan organik di perairan. Tujuan kegiatan ini adalah menyajikan dan menganalisis pelaksanaan edukasi pengelolaan sampah organik rumah tangga menjadi pupuk cair dan kompos agar sampah tidak dibuang lagi ke sungai. Kegiatan dilaksanakan di Kampung Arban Bawah, Desa Gunung Bunder 2, Kecamatan Pamijahan, Kabupaten Bogor pada bulan Mei sampai Juni 2022. Metode pelaksanaan kegiatan dilakukan melalui observasi lapangan, memberikan materi pelatihan, praktik langsung, dan melakukan pemantauan. Analisis data dilakukan secara deskriptif. Edukasi dan aksi dilakukan melalui kegiatan pelatihan, pembuatan pupuk cair dan kompos dari sampah, pembuatan lubang biopori serta pemberian bantuan bak sampah dan pelubang biopori. Hasil pre-test menunjukkan bahwa masyarakat tidak mengetahui tentang mikroorganisme dalam sampah organik dan masyarakat belum mengetahui tentang pengelolaan sampah yang baik. Setelah dilakukan kegiatan pelatihan, diperoleh hasil bahwa masyarakat mengetahui tentang mikroorganisme dalam sampah organik, lubang biopori, dapat mengelola sampah, dan mau melakukan pengelolaan sampah menjadi pupuk cair dan kompos.

Abstract

Tinfoil barb Barbonymus schwanenfeldii is recognized as one of the potential aquaculture commodities in Indonesia. Nonetheless, lack of data on their environmental tolerance causing this issue to become essential to be investigated. The present study was carried out to assess the pH influence on growth and physiological response of juvenile tinfoil barb. Juvenile tinfoil barbs (TL: 5.5 ± 0.8 cm; BW: 2.4 ± 1.0 g) were treated with four pH level treatments (5, 6, 7, and 8) and three replications with the stocking density of 10 fish each aquarium. Fish were kept for 21 days and fed with commercial fish feed. In this study, pH 8 exposure resulted to lower growth of juvenile tinfoil barb compared to pH treatment 5 to 7 (p<0.05). In terms of survival rate, the results show significantly lower value at pH 8 treatment compared to those of pH 6 and 7 treatment (p<0.05), while it is not significantly different with pH 5 treatment (p>0.05). Additionally, this study found the highest value of glucose, cortisol, and aspartate aminotransferase (AST) on pH 8 treatment (p<0.05). On the other hand, pH 8 exposure led to the lowest creatinine, blood urea nitrogen (BUN), and ALP level (p<0.05). In conclusion, the optimal pH for juvenile tinfoil barb rearing ranged around 6-7.

Abstract

Hypoxia is one of the critical issues in aquaculture production systems as it can lead to physiological disturbances in cultured fish. This research aimed to evaluate the tolerance level and physiological responses of domesticated Asian redtail catfish Hemibagrus nemurus reared in various hypoxia conditions. A total of 12 fish/treatment were acclimated to gradually decreased dissolved oxygen treatments until fish experienced aquatic surface respiratory (ASR) and loss of equilibrium (LOE). Cortisol, haemoglobin, and glucose levels were detected in the blood plasma to evaluate the stress response of the fish to hypoxia. The result showed that ASR of H. nemurus was identified at 2.17 ± 0.14 ppm of dissolved oxygen (DO) concentration with the percentage of ASR was 77.67 ± 9.53%, while LOE critical of H. nemurus happened at 0.63 ± 0.15 ppm of DO where 55.56 ± 4.81% of the fish experienced LOE. There were significant differences in the values of physiological parameters (blood cortisol, haemoglobin, and glucose) between control and treatments as fish experienced LOE (P<0.05). In the present  study, it was found that the Asian redtail catfish is classified as a hypoxia-sensitive fish group. Tehis finding is valuable information for the rearing and growing of the fish to provide an optimal DO concentration for their growth and survival.

Abstract

Anthropogenic activity surrounds the Crown Golf ornamental lake may contribute to waste input that could lead to the increasing of nutrient concentration and affect nutrient enrichment in the lake. This research aims to evaluate the water quality of Crown Golf ornamental lake, Pantai Indah Kapuk, North Jakarta based on N and P content. Water sampling was conducted for a year (September 2018 to August 2019) at four sampling locations. The main observed parameters were N (total nitrogen, ammonia, nitrite, nitrate) and P (total phosphate, orthophosphate). The data were analyzed for comparison of observed water quality and standard (Government Decree of Indonesia Republic No 82 the Year 2001), determination of N/P ratio, and determination of pollution level determination using Water Quality Index (WQI) and Pollution Index (IP) based on N and P content. The nutrient concentrations (nitrite, nitrate, and orthophosphate) were lower in the rainy season than in the dry season, while ammonia, total nitrogen, and total phosphate were not different between both seasons. Generally, the water quality of Crown Golf ornamental lake was still meet the standard for recreational activity (Class II). However, the obtained N/P ratio was very high (51:1). The pollution level of this lake is also moderate to bad (based on WQI) and slightly polluted to highly polluted (based on PI). This revealed that the Crown Golf ornamental lake had quite high N and P concentration and potentially causing the decrease of water quality and ecological function.

Abstract

Plankton is aquatic organism that can be utilized as natural food. Hard-lipped barb is one of herbivorous fish that most of its life using plankton as its food source. Growing phytoplankton in pond can be conducted by providing nutrient source, such as fertilizing.  In this study, we examined the growth of hard-lipped barb larvae related to the existence of natural food in different fertilized ponds.  Four types of fertilizer were applied i.e. 100% organic fertilizer (PO), mixing of 85% organic and 15% inorganic fertilizer (PCa), mixing of 60% organic and 40% inorganic fertilizer, and 100% inorganic fertilizer (PA). Hard-lipped barb larvae were put into ponds after fertilizing process. Plankton was observed in ponds and larval intestines (Index of Preponderance and Ivlev Index). The growth of hard-lipped barb larvae was also observed. The result showed that larvae tend to utilize phytoplankton from the class of Bacillariophyceae and zooplankton in the early of its life. Utilizing plankton with those compositions as natural food in the early period generates a good growth performance.  The best performance of growth was shown by larvae in PA treatment which utilized most on zooplankton in the early period. Key words: fertilizer, natural food, hard-lipped barb, plankton   ABSTRAK Plankton merupakan organisme akuatik yang dapat digunakan sebagai sumber pakan alami. Ikan nilem merupakan salah satu jenis ikan herbivora yang hampir sepanjang hidupnya memanfaatkan plankton sebagai sumber makanannya. Cara untuk menumbuhkan fitoplankton di kolam adalah dengan menyediakan sumber nutrien, di antaranya melalui pemupukan. Oleh karena itu, penelitian ini dilakukan untuk mempelajari tingkat pertumbuhan larva ikan nilem berkaitan dengan keberadaan pakan alami yang ditumbuhkan pada media dengan jenis pupuk berbeda. Dalam penelitian ini diterapkan empat jenis pupuk berbeda, yaitu 100% pupuk organik (PO), campuran 85% pupuk organik dan 15% pupuk anorganik (PCa), campuran 60% pupuk organik dan 40% pupuk anorganik, dan 100% pupuk anorganik (PA).  Larva ikan nilem ditebar di kolam setelah proses pemupukan. Pengamatan dilakukan terhadap keberadaan plankton di kolam dan di usus (Indeks Preponderance dan Ivlev).  Di samping itu juga dilakukan pengamatan pertumbuhan larva.  Berdasarkan hasil penelitian diketahui bahwa fitoplankton dari kelas Bacillariophyceae dan zooplankton banyak dimanfaatkan oleh larva di awal hidupnya.  Pemanfaatan plankton dengan komposisi tersebut sebagai pakan alami di awal masa pemeliharaan menghasilkan pertumbuhan yang baik.  Larva dengan pertumbuhan yang paling baik ditunjukkan oleh perlakuan PA yang memanfaatkan zooplankton lebih besar di awal masa pemeliharaan. Kata kunci: ikan nilem, pakan alami, plankton, pupuk
