Abstract

Heavy metals are compounds that can affect the quality of a waters. Various kinds and types of heavy metals that enter and settle in sediments can cause diversity to decrease to the extinction of organisms in the waters. This study was aimed to determine the content of Cd, Pb, and Cu accumulated in water, substrate, and gastropods obtained from Kersik Village, Kutai Kartanegara Regency, East Kalimantan. Samples of water, substrate, and gastropods were collected from 4 stations with 3 repetitions. Water samples, substrates, and gastropods were analyzed using AAS. Concentration ranges of Cd, Pb, and Cu in water were 0.003 - 0.011 mg/L; 0.161 - 0.731 mg/L; and 0.007 - 0.009 mg/L, respectively. The concentration ranges of Cd, Pb, and Cu on the substrate were 0.021 - 0.182 mg/kg; 19.5 - 31.12 mg/kg; and 14.29 - 15.47 mg/kg, respectively. In gastropods, the range of Cd concentrations was 0.509 - 0.675 mg/kg, while for Pb and Cu were 15.96 - 21.52 mg/kg and 57.78 - 92.4 mg/kg, respectively. The concentration of Pb in gastropods at all stations has exceeded the quality standard based on SNI-7387-2009, while the concentration of Cu in gastropods at all stations has also exceeded the quality standard based on BPOM No.03725/B/SK/89. Bioconcentration Factor (BCF) of organisms to sediment (BCFo-s), shows the ability to accumulate Cu in Gastropods which is higher than Cd and Pb. Bioconcentration Factor (BCF) analysis of organisms to water (BCFo-w), showed that the accumulation of Cd, Pb, and Cu were in the low, medium, to high categories. The average comparison of concentrations of the three heavy metals at each observation station was not significantly different (sig. > 0.05).

Abstract

Tilapia is one type of freshwater fish that has high economic value. With the increasing demand by the community, tilapia is cultivated in a semi-intensive system so that bacterial diseases caused by Aeromonas hydrophila arise. One way to treat disease in fish safely is the use of lactic acid bacteria. The purpose of this study was to examine the isolates of lactic acid bacteria in controlling diseases caused by Aeromonas hydrophila in tilapia. This study used a completely randomized design experimental method with 4 treatments and 3 replications. The treatments consisted of feed mixed with Phosphate Buffered Saline (PBS), Enterococcus faecalis isolate, Lactobacillus plantarum isolate and Lactococcus lactis isolate at a dose of 0.1 mL/g of feed at a concentration of 106 CFU/mL and mixed with 0.1 mL of egg white. The results showed that the treatment with lactic acid bacteria affected the condition of clinical symptoms and anatomical pathology of tilapia, but was better than the control treatment. The feed mixed with lactic acid bacteria also had an effect on increasing the immune response and showed higher survival than the control treatment. The condition of water quality in the rearing media showed the normal range for the life of tilapia.

Abstract

Relatively higher density at tree level was Sonneratia alba, Rhizophora mucronata at sapling and seedling level. The highest relative frequency at the tree level was Sonneratia alba, Rhizophora mucronata at the sapling and seedling level. The highest relative dominance at the tree level was Sonneratia alba, Rhizophora mucronata at the sapling and seedling level. The high mastery of these two types is influenced by environmental factors that support growth. Judging from the Important Value Index of the Coastal Mangrove Park area for the tree level it is Sonneratia alba and at the sapling and seedling level Rhizophora mucronata is dominant. In terms of using the Tourism Suitability Index for the mangrove tourism category, the coastal-free mangrove park area is categorized as appropriate (S2). Based on direct observations, the conditions in the Coastal Mangrove Park area are suitable for ecotourism activities, but it is still necessary to develop sustainable areas and manage the area sustainably. Judging by using the carrying capacity of the area, the area of beach-based mangrove tourism parks in the category of mangrove tourism is 104 people per day, to maintain a mangrove ecosystem in order to remain sustainable it is necessary to know the carrying capacity of an area so that the implementation of visitor restrictions can be estimated for the purpose of keeping the ecotourism area sustainable.

Abstract

This research was conducted to determine the effect of inulin on the efficiency of feed utilization and the hematological parameters of red tilapia. This study used a completely randomized design (CRD), with 4 treatments and 3 replications. The doses of inulin used in the treatment were 0,00 g/kg, 1,00 g/kg, 2,00 g/kg and 4,00 g/kg. Tilapia with body length of 6,00-6,50 cm and weight of 4,00-4,50 g were reared in a plastic container with a volume of 40 l of water in a semi-closed water recirculation system for 30 days. Fish were fed with treatment using the at satiation method with a frequency of 3 times a day. The results showed that the administration of inulin had no effect on the efficiency of feed utilization (p>0,05), but gave the best value on hemoglobin levels, hematocrit levels, total erythrocytes, total leukocytes, lymphocyte levels, monocyte levels, and neutrophil levels at dose 2,00 g/kg (p<0,05).

Abstract

Bagan tancap merupakan alat tangkap ikan kategori jaring yang banyak digunakan di Kalimantan Timur. Bagan tancap dioperasikan pada malam atau siang hari sesuai dengan kebutuhan dan situasi di daerah tersebut. Seperti di perairan Lamaru, setiap operasi jaring dilakukan ± 2-3 kali hauling atau jaring yang biasanya dilakukan sebelum tengah malam (21.00-23.59 WIB), tengah malam (00.00-02.59 WIB) dan setelah tengah malam (03.00-06.00 WIB). Penelitian ini bertujuan untuk menganalisis perbedaan waktu angkut tancap Bagan terhadap hasil tangkapan di Perairan Lamaru Kota Balikpapan. Pengumpulan data dilakukan tiga kali sehari dengan menggunakan metode purposive sampling dengan 3 periode pengambilan sampel untuk setiap pengambilan data. Hasil yang ditemukan tangkapan diambil sebelum tengah malam dengan rata-rata 5,52 kg, pada tengah malam jumlah tangkapan rata-rata 3,90 kg, sedangkan setelah tengah malam angka rata-rata yang didapat adalah 7,36 kg. Dari hasil tersebut dapat disimpulkan bahwa perbedaan waktu angkut menunjukkan perbedaan hasil yang signifikan terhadap hasil tangkapan, dan waktu angkut bagan yang paling optimal adalah setelah tengah malam.

Abstract

In general, various human activities cause eutrophication in water bodies. Lentic system is vulnerable to discharge of pollutants from surrounding areas. Similar scenarios most likely occur in Polder Air Hitam Lake in Samarinda City. The goal of this study was to investigate the trophic status of this urban lake using modified Carlson index with the indicator of chlorophyll-a and total phosphate/ Spatially the variation of chlorophyll-a was 32.6 – 97.3 µg/L, and total phosphate was 0,141 – 0,225 mg/L. The calculation of Carlson trophic state index resulted 73.78, which indicated hypereutrophic status. This condition was not ideal for a healthy lentic system. In the future a related treatment is required to optimize multiple functions of this urban lake.

Abstract

Tiger prawn (Penaeus monodon) is a type of shrimp from the Penaeidea family and is one of the caught in Samboja waters. This research was conducted in November-December 2022 in Samboja Kuala Waters, Kutai Kartanegara by catching shrimp at night using trawl fishing gear. The sample used was 100 tiger prawns (Penaeus monodon) with 42 females and 58 males. This study aims to determine the morphometric characters of tiger shrimp (Penaeus monodon) and to analyze the morphometric measurements. In the analysis using Ancova, the results obtained were 12 morphometric characters of tiger shrimp (Penaeus monodon) with significant values greater than 0.05, namely RST, PK, PRT, PRN, PT, PP, PKB, PTB, PNB, PE and PTK . So based on the initial hypothesis, if the significant number is greater than 0.05 Ho, it is accepted, which means that there is no relationship between the morphometrics of male and female tiger shrimp (Penaeus monodon).
