Mangrove forests as natural ecosystems, have high ecological and economic value. Rapidly growing population, causing the needs of human life is increasing, as a consequence of increased development and settlement. This will create pressure on natural resources, where the utilization has not yet taken into consideration any losses that have ecological impacts. Implementation of ecotourism system in mangrove forest ecosystem is an approach in sustainable utilization of mangrove forest ecosystem. The ecosystem suitability index for mangrove tourism in Village Pasir Mempawah Hilir Mempawah District is classified into very suitable (SS) and conditional (SB) categories for ecotourism development. This shows that the mangrove area in the Village Pasir Mempawah Hilir Mempawah District is suitable to serve as a tourist area. An alternative strategy of ecotourism management of mangrove priority in the coastal area of Pasir Village, Mempawah Hilir, Mempawah District, is to increase the effort of mangrove planting on the beach (replanting) in ecotourism development area. Thus, all areas in the location meet the criteria appropriate for mangrove ecotourism areas based on ecological parameters.

The presence of heavy metals in the aquatic environment must be monitored continuously. This study aims to determine the amount of heavy metal content of Cadmium (Cd) and Lead (Pb) on Vaname Shrimp (Litopenaeus vannamei). Determining the value of Cadmium (Cd) and Lead (Pb) using an AAS (Atomic Absorption Spectrophotometer) device. It is known that the highest Cd content in the sample 4 (market pancing) which is worth 0.011 mg/kg, and the lowest is in the sample 6 (market sei kambing) which is worth 0.004 mg/kg. The value of the highest Pb value is found in the sample 3 (market merah) worth 0.019 and the lowest value is the sample 5 (market petisah) worth 0.008. So that the results of these tests can be concluded, that the content of heavy metals Cd and Pb in each sample of vaname shrimp is classified as low according to the World Health Organization (WHO), namely the maximum limit of Cd is 5.0 and the maximum limit of Pb is 2.0 while according to EUROPEAN UNION the limit of calcium Cd is 0.2 and the maximum limit of Pb is 0.5 because the vaname shrimp sample is still safe for consumption and can be an export commodity.

Aquaponics is a combination of aquaculture and hydroponics system. This system is expected to be able to overcome the problems of waste from aquaculture by utilizing Nitrogen (N) and Phosphorus (P) for vegetables. There are several obstacles found in aquaponics systems such as high suspended organic matter produced from the feed residue and fish metabolism. The addition of natural filters, namely freshwater mussels (Pilsbryoconcha exilis) is expected to solve these problems. This research was conducted for 40 days. The design used in this study was Factorial Completely Randomized Design with two main factors namely mussels density as factor-A and time of observation as factor-B. The treatments were P1 (0 mussels density), P2 (15 mussels density), and P3 (30 mussels density) for factor-A while time of observation were factor-B (D-0, D-10, D-20, D-30 and D-40). Each treatment was conducted in three repetition. The results showed that the time observation gave significantly different on water condition changes (P <0.05), which will increase TSS, turbidity and chlorophyll value along with the increasing of time. P exilis in aquaponics was effective in reducing turbidity and chlorophyll concentration (P <0.05). Therefore, aquaponics system with the highest mussels density (P3) with has lower turbidity and chlorophyll value than the one with 0 mussels density (P1).Â

The research aimed to assess the performance of Pregnant Mare Serum Gonadotropin (PMSG) and Human Chorionic Gonadotropin (HCG) hormone injection combined with vitamin mix to induce the rematuration of Striped catfish Pangasianodon hypophthalmus broodstock. Three PMSG and HCG treatments of 5 and 2,5 IU; 10 and 5 IU;also 20 and 10 IU/kg of broodstock body weight dosage combined with vitamin mix addition to fish feed and one control was used with four replications. The broodstock was reared for four weeks and weekly sampling for GR and SGR as well as hormone injection were performed. For the following two weeks, the broodstock was observed for maturation. Artificial spawning was conducted for broodstock reaching gonadal maturity. Statistic analysis of observed variables showed insignificant differences among the three treatments in rematuration parameters. The rematuration rate resulted in a 100% pregnancy. Broodstock treated with 10 IU PMSG and 5 IU HCG/kg of spawner body weight was able to reach maturity and spawned with the larval survival rate on the fourth day at 84,81%, thus it can be concluded that 10 IU PMSG and 5 IU HCG/kg of body weight as the best dosage.

Pasaran Island waters is the location of green mussel cultivation (Perna viridis), where the waters has the potential to experience heavy metal pollution including Cadmium (Cd). Green mussels are filter feeders and have a slow movement, thus they have the potential to experience heavy metal bioconcentration on their bodies. The aim of this study was to determine the bioconcentration of heavy metal cadmium (Cd) in green mussels (Perna viridis) which were cultivated in the waters of Pasaran Island. Samples were collected in February 2018 in green mussel cultivating cages of Pasaran Island water with 3 and 6 cm mussel size. Sampling was taken at three stations with three replications each. The Cd content was analyzed using AAS method. The results showed that the water content of Cd at the observation location ranged from 0.022 to 0.024 mg/l. The content of Cd of mussel meat is 0.030 to 0.033 mg/kg, the value is below the threshold based on Indonesian National Standard (SNI). The BFC value of 3 cm mussel is 1.33 mg/kg, while the 6 cm mussel is 1.47 mg/kg which indicates that the green mussels on Pasaran Island are accumulatively low on Cd.
