Abstract

The aim of this study was to monitor the condition of water quality in the aquaculture area of fix net cage culture system (KJT) at Lake Tondano, Eris Village, Eris District, Minahasa Regency which included temperature, pH, DO, TDS, Turbidity, NO2, NH3, PO4  and sediment (N, Nitrogen and P, Phosphorus) in  a different time. This research was conducted from March to May 2021 using a survey method. The research activities consisted of direct measurements in the field (in situ) using a Horiba U-5000G instrument and laboratory analysis (ex situ) at the BTKLPP Class 1 Laboratory and the BARISTAND Laboratory in Manado for primary data. Primary data was carried out at 3 points, Point 1 represented around residential activities, Point 2 where the areas of cultivation activities, and Point 3 where outside of cultivation and settlement activities. Primary data was compared with secondary data i.e, publish articles and then processed in the STORET method. Data were evaluated to the water quality parameters standard according to the Indonesian Government Regulation number 22 of 2021. The results showed that the water temperature ranged between 26.3 - 28.07 0C, Turbidity (10.5 - 24.4 NTU), TDS (0.167 - 0.172 g/L), pH (3.79 - 7.84), DO (1.87 - 9.05 mg/L), NH3 (0.12 - 0.26 mg/L) , NO2 (0.001 - 0.064 mg/L), PO4 (0.2 mg/L - 1.67 mg/L). In the sediment samples, N was found in the  ranged of 0.20% - 0.26% and  P (0.48% - 2.69%). It can be concluded, the condition of water quality in the aquaculture area using KJT in Eris Village is categorized as class C (medium polluted) and N in the sediment criteria is moderate and the content of P in the sediment criteria is very low.

Abstract

This research was conducted to determine the optimal density of kale plants as biofilter in an aquaponic system that can trigger the highest growth and survival of tilapia. The experiment was designed in a completely randomized design (CRD) with 3 treatments and 3 replications so that there were 9 experimental units. The factor tested was the different density of kale plants as biofilter in the aquaponics system, where treatment A: 6 kale plants/0,24m2, B: 12 kale plants/0,24m2, and  K: without kale plants (as control). This study was conducted for 28 days.  Collected data  included weight, length and number of fish, which were then converted to  absolute growth rate (weight and length) , daily growth rate, survival rate and kale plant growth. Data  were analyzed using ANOVA  and then Least Significance Differences (LSD) for  further analysis.   The results  showed that the different density of  kale plants had no significant effect on absolute growth rate (weight and  length)  and daily growth rate, but had a significant effect on the survival rate of fish. The LSD results  showed that density of 6 kale plants/0,24m2 (A) were not significantly different from that of 12 individuals kale plants/0,24m2 (B), but both treatments were significantly different from the control (K).  The range of ammonia  was between 0.29 – 0.91 mg/l, nitrite 0.55 – 1.06 mg/l, and nitrate 10 - 47 mg/l.

Abstract

Kappaphycus alvarezii is a marine alga cultivated in Indonesia and produces carrageenan. Carrageenan is a product used in the cosmetic, food, and pharmaceutical industries. This study aimed to test the viscosity and gel strength of refined carrageenan with the addition of natural dye phycoerythrin from the algae Halymenia durvillei with different concentrations. Refine carrageenan was made using alkaline solvents of 4% NaOH and 5% KOH and then boiled using a pressure cooker. The results showed a reddish color change in the pure carrageenan refinement with the addition of phycoerythrin pigment, especially at a concentration of 50%. The average value of refined carrageenan viscosity for 4% NaOH concentration was 49.22 – 50.27 cP, and 5% KOH concentration ranged from 47.16 – 50.12 cP. Testing the gel strength of the refined carrageenan, the average NaOH 4% was 72.67 – 82.00 mm/g/sec, and the 5% KOH concentration was 81.00 – 81.78 mm/g/sec. The addition of phycoerythrin pigment to refine carrageenan had no effect on viscosity and gel strength. Drying at a temperature of 100oC obtained a water content of semi-refined carrageenan between 2.91 - 4.38%, this value is in accordance with the standard for carrageenan water content from FAO, which is a maximum of 12%.Keywords: Carrageenan, phycoerythrin pigments, Kappaphycus alvarezii, Halymenia durvillei, viscosity, gel strength.AbstrakKappaphycus alvarezii merupakan alga laut yang dibudidayakan di Indonesia dan penghasil karagenan.

Abstract

Tributiltin (TBT) is an organotin compound that is still widely used as a toxic biocidal additive in antifouling paints. These compounds are classified as pollutants that are very difficult to decompose in waters. The test of the concentration of TBT in seawater was carried out at the WLN Laboratory (Water Laboratory Nusantara) Manado. Nitrate, nitrite and ammonia concentration tests were carried out at the Laboratory of the Manado Industrial Service and Standardization Center (BSPJI). Measurement of the physical and chemical parameters of seawater used: Temperature, Brightness, pH, Dissolved Oxygen (DO), Salinity and Turbidity in situ. Analysis of the concentration of Tributiltin (TBT) compounds in seawater in the waters of the Lembeh Strait in the cultivation areas of Point 1 (Tanjung Rarandam), Point 2 (Kalapa Dua), Point 3 (Papusungan) in the Lembeh Strait showed a concentration of <0.01 μg/L, which is still in the safe range below the standard limit of seawater quality for biota (0.01 μg/L). Measuring water quality in the Lembeh Strait aquaculture area, the DO value ranges from 7.83-8.34 ppm. Salinity values ranged from 30.99-31.24 ppt. The pH value ranges from 9.37-9.42. The temperature value ranges from 27.87-27.69 °C. The brightness value ranges from 3.12 m-3.39 m. The turbidity value ranged from 0.63-1.22. The nitrate value of 1.98-2.19 mg/L, far exceeding the limit set (0.06 mg/L) for marine life, indicates a potential risk to the ecosystem. The concentration of Nitrite in the waters is still in accordance with the general water standards, ranging from <0.005 mg/L to 0.02 mg/L. The concentration of Ammonia is below the water quality standard threshold at all points of 0.3 mg/L, which is still safe for marine life and aquaculture activities in these waters in accordance with the seawater quality standards in Government Regulation No. 22 of 2021 Attachment VIII concerning the Implementation of Environmental Protection and Management.
