Seaweed is one of the potential marine commodities to be developed in coastal areas. To get maximum income, farmers must be able to increase production and reduce production costs. Therefore farmers must be able to use farming inputs efficiently. This study aims: (1) to find out how much the income of seaweed farmers (Eucheuma Cottoni) in the Pantai Amal Village; (2) to analyze the factors that influence the production of seaweed (Eucheuma Cottoni) in Pantai Amal Village; (3) to find out the elasticity of seaweed production (Eucheuma Cottoni) in the Pantai Amal Village. The method used is income analysis, multiple linear regression analysis through the Cobb-Douglas approach and production elasticity. The samples used were 60 seaweed farmers. Determination of the sample using the Sampling Quota. The analysis shows that the total costs incurred by farmers in seaweed farming is Rp. 8,121,768 with revenues of Rp. 19,934,167 so that the income of farmers is Rp. 11,812,399 in one seaweed production. The estimation results of the model show that the variable seed (X1), labor (X2), rope stretch (X3) and experience of farming (X4) significantly influence seaweed production. Seed elasticity value is 0.565, labor elasticity is 0.105, stretch rope elasticity is 0.438 and business experience elasticity is 0.216. These results indicate that Ep 1 (between no and one). So that the seed variables, labor, stretch ropes and farming experience are inelastic. This means that the four variables have not made a major contribution to seaweed production in the Pantai Amal Village of Tarakan City.

Abstract The massive expansion of Eucheuma cottonii seaweed cultivation in the waters of Nunukan Island has triggered complex spatial-use conflicts and environmental degradation, reflecting the phenomenon of the Tragedy of the Commons. This study aimed to analyze the dynamics of marine spatial governance, map power relations among stakeholders, and formulate adaptive management strategies for sustainable seaweed cultivation. A mixed-methods approach with a Sequential Explanatory design was employed, integrating spatial analysis, perception surveys of 38 key respondents, and Focus Group Discussions (FGDs). Stakeholder mapping was conducted using the Power-Interest Grid matrix, while strategy formulation was determined through Quantitative SWOT analysis (IFAS/EFAS). The results revealed the occurrence of regulatory obsolescence, in which spatial planning instruments (RZWP3K 2018) failed to anticipate a 65% surge in cultivation area expansion (reaching 29,578 hectares), resulting in physical intrusion of approximately 6,000 hectares into the Nunukan Port Entry Shipping Lane, thereby endangering navigational safety. The stakeholder analysis showed the dominance of informal actors ("Big Bosses") as key players who possessed de facto power through patron-client networks, weakening the effectiveness of formal law enforcement. The SWOT analysis placed the current strategic management in Quadrant IV (Defensive) at coordinates (-1.05; -0.61), indicating critical internal weaknesses amidst high external threats. Accordingly, the study recommends a Survival Strategy comprising immediate sterilization of red zones within shipping lanes, the enforcement of a moratorium on new cultivation areas to restore environmental carrying capacity affected by ice-ice disease, and the formalization of the role of "Bosses” into a co-management scheme to enhance zoning compliance and governance effectiveness.

Kappaphycus alvarezii is one of the main sources of carrageenan with high economic value. The process of producing sea salt from this seaweed generates residue (waste) that has not been optimally utilized. This study aimed to identify the properties of carragenan derived from the by-product (residue) of K.alvarezii seaweed salt production collected is Sebatik Island utilizing potassium hydroxide (KOH) solvent, and to compare it with carragenan extracted from whole seaweed. The investigated parameters and encompassed yield, moisture conten, sulfate conten, ash content, and viscosity. The result showed that the moisture content of the salt residue was 21.68%, which was lower than that of the whole seaweed (28.60%). The carraginan derived from salt residue contained 8.33% water, 1.34% sulfate, and 32.33% ash and had q viscosity of 20.00 cPs. All parameters, except sulfate concentration, mer the Indonesian National Standard (SNI 8391-1:2017). The relatively high viscosity indicated that carragenan derived from salt residue still has potential applications, particularly in non-food industries. Therefore, sea salt production residue from K. alvarezii can be utilized as an alternative raw material in the production of economically valuable carrageenan.
