The beating of fishermen due to the Covid-19 pandemic does not necessarily damage the Punggawa-Sawi relationship in Beba, Takalar Regency. The obedience of the Sawi people in choosing to stay with the Punggawa must be photographed from a different angle. This relationship can no longer be seen as a relationship of material interests, such as wages. The reason is, the acquisition of material in their relationship in the midst of the pandemic has also fallen sharply. This study aims to identify Punggawa authority and Sawi compliance that can still exist despite being hit by the Covid-19 pandemic and unfavourable conditions. This study uses a qualitative method with case study analysis. Data sources are divided into two categories, namely primary and secondary sources. Data was collected by using in-depth interviews, observation and documentation techniques. Specifically and tactically, the data analysis technique was carried out following the Miles and Huberman model by reducing data, presenting data and drawing conclusions. The results of this study indicate that the Punggawa authority which is woven into the Punggawa-Sawi relationship in Beba is obtained traditionally. They are not bound by a set of officially announced rules. Sawi's obedience to the retainer was not solely due to material interests. However, their obedience is based more on the characterization of Punggawa because of his generosity and the existence of a familial or kinship relationship between Punggawa and Sawi. This condition makes the relationship between Punggawa and Sawi very close so that it does not waver even in the midst of the Covid-19 pandemic.

This study aims to investigate the impact of varying the depth of water on the growth and productivity of seaweed Kappaphycus alvarezii. The study was carried out in the seas of Pallette. The research methodology used in this study incorporates three different planting depth treatments, specifically 1.5 meters, 3 meters, and 4 meters. In each treatment, 50 grams of Kappaphycus alvarezii seeds per bunch were used. The findings of this study indicate that seaweed cultivation at a depth of 1.5 m yields significantly favourable outcomes compared to the treatments conducted at depths of 3 m and 4 m, where growth is comparatively less optimal. This occurrence can be attributed to the diminished level of light penetration at such a depth. There is an inverse relationship between the depth of seaweed planting and the rate of weight gain. The optimal depth for seaweed cultivation for 42 days is 1.5 meters, with an average specific growth rate of 3% daily. On the contrary, the treatment carried out at a depth of 1.5 m showed the most substantial increase in biomass, averaging 122 g. Additionally, the maximum yield of seaweed was observed in the same treatment, precisely measuring 1,208 g/m².

The plant species mangrove has been knowed to be effective for the bio-desalination process. However, there is currently no scientific evidence supporting the ability of mangrove bio-desalination when implemented through the floating method. This laboratory-scale study aimed to evaluate the bio-desalination of several mangrove species using the floating method. This study consisted of four treatments and three replicates. Treatments included a control group without mangroves (treatment A) and three treatments using mangroves (treatments B, C, and D), Bruguiera sp., Rhizophora sp., and Avicennia sp., which were positioned floating in a tank using a tray. During the eight weeks of rearing, nutrients were provided through 60 mL liquid NPK fertilization. The results showed that there was a decrease in salinity concentration in all mangrove treatments between 22.5-23.9 ppt from the initial salinity of 30 ppt. Different results were observed for the treatment without mangroves, and the salinity concentration tended to increase until the end of the research to 31.6 ppt. The highest Salinity Reduction Efficiency (SRE) was achieved by Avicennia sp.. (25.1%), followed by Rhizophora sp. (22.8%), and the lowest in Bruguiera sp. (20.3%). The results of this study showed that bio-desalination using mangroves had a significant effect on SRE, and each treatment indicated a significant difference (p<0.05). The results of this study provide initial evidence of the potential of the mangrove floating method for bio-desalination of seawater into brackish water.
