Abstract

Changes in nutrient concentrations can be caused by anthropogenic activities in coastal and marine waters. This affects the abundance of phytoplankton. The waters experiencing it are the waters of Kassikebo Pangkep, South Sulawesi, Indonesia. For this reason, research has been carried out to analyze the abundance and structure of phytoplankton communities in these waters, from January to July 2022. To identify phytoplankton, 100 L of seawater samples were filtered, which were taken at each station. The results of that water filter, identified in the laboratory. The results showed that the classes of phytoplankton found were Bacillariophyceae and Cyanophyceae. Species found such as Skeletonema and Detonula. The results of One-way ANOVA showed that phytoplankton abundance was not significantly different between observation stations (p>0.05). Changes in phytoplankton abundance are caused by pH.

Abstract

This study aims to determine the existing condition of the pond area that has the potential for aquaculture, estimate the business feasibility of aquaculture systems, build aquaculture models using dynamic analysis to see the most sustainable aquaculture system, develop dynamic models and simulate various scenarios for sustainable management. The applied aquaculture system was analysed with business feasibility by calculating total cost (TC), total revenue (TR), revenue, R/C and pay back period (PBP). Modelling of sustainable management of Vanname shrimp farming areas is done by formulating scenarios and simulation time and making dynamic models using Stella 9.0.1 software, all scenarios are simulated in a vulnerable time for the next 20 years. The results showed that the most effective cultivation system in 3 sub-districts is a semi-intensive system capable of returning investment or pay back period (PBP) which is about 1.4-1.6 years compared to the traditional system which is about 2.7-3.7 years. The simulation results show that the 3333 scenario in terms of cultivation technology is the best scenario or optimistic scenario to run so that the management of vanname shrimp farming in Mamuju Regency can be sustainable because in the next 20 years most of the cultivation technology will switch from traditional systems to semi-intensive systems. Keywords: Dynamic Model, Business Feasibility, Vanname Shrimp.

Abstract

Wilayah pesisir dan pulau kecil (P2K) memiliki nilai strategis karena sekitar 60 persen penduduk Indonesia hidup di wilayah P2K. Selain itu hampir 95 persen kegiatan perikanan Indonesia terkonsentrasi pada Wilayah P2K dengan kontribusi sekitar 76 persen terhadap produksi perikanan nasional. Wilayah P2K beserta sumberdaya alamnya juga memiliki arti ekonomi yang penting bagi pembangunan, karena wilayah P2K merupakan kawasan yang secara hayati sangat produktif. Sekitar 85 persen dari biota laut kehidupannya bergantung pada ekosistem P2K, seperti hutan mangrove, padang lamun, terumbu karang dan estuaria (Tuwo dkk, 2005). Oleh sebab itu, wilayah P2K perlu mendapat perhatian yang sungguhsungguh dari semua pihak, khususnya para pimpinan.

Abstract

ABSTRACT: The present study aims to determine the effect of conwy fertilizer concentration on the growth of Gracilaria sp. cultivated on a laboratory scale. This research was conducted at the Multitrophic Laboratory of the Hasanuddin University Research Activity Center, Makassar. A completely randomized design was applied for 3 treatments: PC1 treatment (0.5 ml of conwy fertilizer); PC2 treatment (1 ml fertilizer conwy); and PC3 treatment (1.5 ml of conwy fertilizer) and 3 replicates for each treatment. The growth, performance, pigment and water quality were recorded. Analysis of variance (ANOVA) was performed. The results obtained were PC 1 treatment was the treatment that had the highest growth with an average of 13.41%, followed by PC 2 treatment at 12.48% and the lowest treatment occurred in treatment to PC 3 with an average growth of 12.09%. ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi pupuk conwy terhadap pertumbuhan rumput laut Gracilaria sp. yang dibudidayakan dalam skala laboratorium. Penelitian ini dilaksanakan di Laboratorium Multitrofik Pusat Kegiatan Penelitian Universitas Hasanuddin Makassar. Metode yang digunakan adalah metode eksperimental RAL (Rangkaian Acak Lengkap) 3 perlakuan dan 3 kali pengulangan, antara lain perlakuan PC1 (0,5 ml pupuk conwy); perlakuan PC2 (1 ml pupuk conwy); dan perlakuan PC3 (1,5 ml pupuk conwy). Parameter uji yang diamati pada penelitian ini yaitu pertumbuhan, pigmen dan kualitas air. Data yang diperoleh dianalisis dengan menggunakan analisis ragam (ANOVA). Data yang menunjukkan pengaruh yang nyata dilanjutkan dengan uji lanjut W-Tukey. Hasil yang diperoleh perlakuan PC 1 merupakan perlakuan yang memiliki pertumbuhan yang paling tinggi dengan rata-rata 13,41%, diikuti pada perlakuan PC 2 12.48% dan perlakuan yang terendah terjadi pada perlakuan ke PC 3 dengan pertumbuhan rata-rata 12.09%.
