“…Referring to Saimima et al, (2020), the growth rate of baranong fish with the IMTA system was higher than without IMTA. Research by Radiarta and Erlania (2016) regarding the IMTA system in Grubuk Bay, Lombok, also showed that the specific growth rate of cultured organisms to be 2.17-2.63% per day.…”

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Abstrak Penerapan penukar panas tube bank sirip pelat datar staggered untuk sebagai sistem pemulihan limbah panas untuk memanfaatkan limbah panas dari pengering konvektif dengan suhu < 55 °C yang terbuang ke lingkungan. Penelitian bertujuan untuk memperoleh suhu media pengering yang efektif dan efektifitasnya maksimal untuk mempersingkat waktu pengeringan rumput laut dan menghemat konsumsi energi listrik. Metode penelitian eksperimental dilakukan dengan memvariasikan suhu media pengering dari 40 hingga 80 °C pada kecepatan udara 2 m/s, masukan panas 400 W, dan kelembaban relatif 30% konstan pada kondisi pengoperasian sebelum dan sesudah aplikasi sistem pemulihan panas limbah. Data suhu, kecepatan udara, kelembaban relatif, dan masukan panas diambil setelah mencapai kondisi tunak. Hasil penelitian menunjukkan efektivitas menurun dengan meningkatnya suhu media pengering, dimana efektivitas maksimum pada suhu 40°C sebesar 43,48% dan 89,00%, sedangkan efektivitas minimum pada suhu 80°C sebesar 20,05% dan 68,19% untuk kondisi operasi sebelum dan sesudah penerapan sistem pemulihan limbah panas. Waktu pengeringan minimal rumput laut pada tmp 40 °C untuk kondisi sebelum dan sesudah penerapan waste heat recovery masing-masing adalah 11,75 dan 11 jam. Penghematan konsumsi energi listrik maksimum pada tmp 80 °C sebesar 5790,16 kWh atau 15,52%, dan penghematan minimum pada tmp 40 °C sebesar 2391,39 atau 23,13%. Disimpulkan bahwa pengering konvektif panas limbah rumput laut pada kondisi operasi temperatur ruang pengering 40°C mempunyai tingkat efektif sebesar 46,03%, waktu pengeringan 11 jam, dan menghemat konsumsi energi listrik sebesar 23,13%.

“…Meanwhile, the oxygen content based on the measurement results (Table 3) shows good conditions for seaweed. The desired dissolved oxygen content in aquaculture systems is about 5 ppm, while the dissolved oxygen concentration of <3 ppm is a barrier for most aquatic organisms (Radiarta & Erlania, 2015).…”

Blue economy is a development concept that develops by relying on marine or aquatic resources. An increase in carbon dioxide (CO2) in the atmosphere is fueling climate change. This study aims to analyze the rate of carbon uptake in the waters, using seaweed Kappaphycus alvarezii which utilizes carbon to be converted into biomass before returning to the air. The results showed that highest carbon absorption rate was found in location A with the highest total carbon absorption of 94.87±0.77 tons C/planting cycle, then treatment B with 83.96±0.54 tons C/planting cycle, and the lowest in treatment C with 76.88±0.18 tons C/planting cycle. Water quality parameters are still mostly in decent condition for the cultivation of Kappaphycus alvarezii seaweed. Salinity conditions of waters are relatively high (35-39 ppt) even though the optimum seaweed grows in the range of 30-34 ppt. The conclusion of the study is that the highest total carbon is found at Location A, which is 94.87±0.77 tons C/planting cycle. The suggestion of this study is that it is necessary to analyze the suitability of seaweed cultivation land with various water quality parameters, so that mapping of potential types of seaweed that can be cultivated according to the characteristics and quality of the waters.
