Sea waves in Bengkulu Waters vary due to the influence of monsoon winds and global climate. Seasonal variations in significant wave height (SWH) obtained from altimetry satellite imagery in five regions representing Bengkulu, namely Mukomuko Waters, North Bengkulu, Bengkulu City, Seluma, and Kaur can be used to monitor sea waves. The coordinates of the five regions representing Bengkulu Waters are as follows: Mukomuko is located at 2°40'20.82" S, 100°38'47.12" E; North Bengkulu at 3°20'6.55" S, 101°4'59.68" E; Bengkulu City is located at 4°0'7.57" S, 101°31'49.10" E; Seluma is located at 4°20'0.00"S, 102° 0'0.00"E; and Kaur is located at 5°0'59.65"S, 102°49'24.50"E. The data used for five years (2018-2022) is in the form of an average daily SWH every 3 hours and is processed using Panoply software to display the distribution of SWH and time series for each of the five regions in Bengkulu Waters. The results of the study show that the highest sea waves occurred in Kaur Waters, reaching 3.9 meters in August 2022 with an average wave height of 1.73 meters. Meanwhile, the lowest sea wave height occurred in Mukomuko Waters which reached 2.7 meters in January and February 2022, with an average wave height of 0.3 meters. Sea wave height in Mukomuko Waters, North Bengkulu Waters, Bengkulu City Waters, Seluma Waters, and Kaur Waters showed an increasing trend over the past five years. The relationship between significant wave height and season shows a consistent pattern.</p>2025-05-15T00:00:00+00:00Copyright (c) 2025 Risky Budi Yarmanto, Lizalidiawati, Irkhos, Suhendrahttps://ejournalfpikunipa.ac.id/index.php/JSAI/article/view/518Analysis of Rhizophora mucronata mangrove fruit application in enhancing mangrove tourism within the Mandar Village Community, Banyuwangi Regency2025-04-08T03:19:06+00:00Mochammad Fattahmochammadfattah@ub.ac.idLuchman Hakimluchman@ub.ac.idSoemarno Soemarnosmno@ub.ac.idPudji Purwantipudjipurwanti@ub.ac.id<p>The use of mangrove fruit to create economic benefit for the community is anticipated to bolster conservation efforts for the mangrove environment. In Mandar Banyuwangi Village, one application of mangrove fruit is its conversion into flour. This study aimed to examine the proximate composition of Rhizophora mucronata mangrove flour and evaluate the profitability of processing this flour into pastries. The analysis conducted encompasses the proximate content test (including protein, fat, water, ash, and carbs) and a profit analysis that factors in the cost of goods sold (COGS). Mangrove flour manufactured by Poklahsar “Mina UPA Karya” is derived from the fruit of Rhizophora mucronata. The processing method necessitated seven days to manufacture mangrove flour. The proximate composition of mangrove flour, as per SNI criteria, includes water and carbohydrate content, although protein, fat, and ash content are marginally over or below SNI specifications. Mangrove flour is utilized in a variety of desserts, including nastar, kastengel, cookies, almond chocolate, roses, jam sumprit, chocolate sumprit, peanut cake, and krispi brownies. Products made using processed mangrove flour in pastries yield a profit margin of 9.16% of the cost of goods sold (COGS). The R/C, BEPs, BEPq, profit, and profitability ratio of the mangrove flour processing business indicate profitability, since they go over the minimum requirements of profitability criteria.</p>2025-05-07T00:00:00+00:00Copyright (c) 2025 Mochammad Fattah, Luchman Hakim, Soemarno Soemarno, Pudji Purwanti
