Abstract

The fishing ground of the floating lift net fishing fleet in each season in the TPK Kei Kecil conservation area has different economic value because the number of catches, fleet income, and operational costs of the fleet operating in the fishing ground of Ngaf-Ohoiew Island, Sepuluh Island, and Lima Island in each season is different. This study aims to analyze the economic fishing ground of the floating lift net fishing fleet in each season in the region. The locations of this research are Ohoi Namar, Ohoi Selayar, Ohoi Ohoililir, and Ohoi Dian Island, and it will be carried out in May – Oktober 2023. Data was collected using the survey method; respondents were determined using purposive sampling. The data that has been collected includes fishing ground, catches, fleet revenues, and fleet operational costs, then analyzed descriptively, qualitatively, and quantitatively, then presented in the form of pictures. The study recommends that the economical floating lift net fishing fleet fishing area in the TPK Kei Kecil conservation area in transition season 1 and 2 is a fishing ground located in the waters of Ngaf-Ohoiew Island because it has a high income from operational costs of Rp 136,059,000 in transition season 1 and Rp 126,420,000 in transition season 2, respectively while in the eastern season is the fishing ground in the waters of Pulau Lima because the average income is Rp 157,669,000.

Abstract

Seaweed is a superior commodity for aquaculture and is a raw material for export. Sustainability of exports requires sustainable seaweed production to ensure the sustainability of raw materials to fulfil market demand from buyers and consumers. In this regard, this research aims to analyze the supply chain, margins and marketing efficiency of Kappaphycus alvarezii seaweed cultivated by the community in Nunukan District, North Kalimantan. This research is classified as a quantitative type of research with a survey method using an interview method through the distribution of questionnaires to seaweed business actors. The results of the research show that information was obtained about the Kappaphycus alvarezii seaweed supply chain through three marketing channels, namely (1) channels from seaweed farmers to collectors and consumers, (2) channels from seaweed farmers to consumers and (3) channels from collectors to consumers . Seaweed production produced by farmers does not have a minimum production quantity standard so that the seaweed produced can be sold at any time to collectors according to a predetermined price agreement. Meanwhile, there are differences in seaweed marketing margins between respondents in the marketing network, and price differences at the collector level cause price differences at the consumer level. The resulting marketing efficiency is at an efficient level (≤ 50%). Seaweed marketing in Nunukan is classified as efficient because the share received by seaweed farmers as producers is below 50%. The efficiency of seaweed marketing depends on the level of marketing margin and the share received by seaweed farmers.

Abstract

Phytoplankton has been known to play its role as an indicator of water quality. In the intensive cultivation system of Pacific White Shrimp (Litopenaeus vannamei), phytoplankton can respond to water quality dynamics simultaneously. However, the impact of weather differences on community structure and phytoplankton diversity has not been further investigated. Here we analyze water quality and phytoplankton diversity in ponds, including uniformity and dominance. The results showed that 12 genera of phytoplankton were found in sunny weather, whereas 9 genera were found in rainy weather. Phytoplankton diversity in sunny weather is greater. The diversity index (H') value when it rains and shines is in the medium category with a stable community structure and low polluted water conditions. The uniformity value (E') is moderate. No plankton dominance was found (C ≤ 0.5) with the highest important index value during rain being Rhizosolenia sp. and Chlorella sp. when it's sunny. Water quality in general does not differ and meets quality standards except for the nitrate and phosphate values. Nitrate and phosphate values in both weather conditions exceeded standard standards. Differences in the types of phytoplankton present in different weather can be caused by the brightness that enters the water. Apart from that, the volume of water and the dilution and mixing effect of rainwater can cause differences in the amount. The source of growth nutrients is a supporting factor for phytoplankton growth.
