This study aimed to evaluate the growth and yield of carrageenan from Kappaphycus alvarezii (Doty) which were cultured at different depths of water. The study lasted for 49 days, using two strains (green and brown), three initial weights (50, 100, 150 g), and five levels of depth (1, 2½, 4, 5½, 7 m). The results showed significant differences between growth rate and yield of carrageenan on the three treatments (P<0.01). The highest growth rate of both morphology types of green and brown occur on the same weight and depth i.e., at initial weight 100g and depth 2½ m, respectively at 5.68 and 6.05% day-1. The yield of carrageenan is likely to increase in depth with the highest value at a depth of 7 m, respectively 17.12% at green type and 14.63% at brown type. The results showed that reducing growth may increase the yield of carrageenan by the increasing of water depth. Based on these results, this study can be applied to another location as long as the quality of water allows farming activities.

Cultivation of Kappaphycus alvarezii has been carried out by inverted pyramid method in the deep water of Saparua Bay. This study aims to analyze the daily growth rates, biomass productions and carrageenan yields of the green and brown strain of K. alvarezii with different depth of water by inverted pyramid method in deep seawaters. K. alvarezii with an initial weight of 100 g were planted successively at the depths of 1, 3, 5, 7 and 9 m during four growing seasons that last for 49 days in every season. The results showed that the highest growth rate and biomass production were on green strain at 1 m depth and brown strain at 3 m depth which were 4.18% and 749.29 g/m2 then 4.19% and 754.51 g/m2, respectively. While the highest carrageenan yield was on the green and brown strain at 9 m depth which were 16.53% and 14.85%, respectively. The carrageenan yields gradually increase with the increasing of water depths which contradict to growth rate and biomass production that showed the better results at lower depths (1 and 3 m). In conclusion, seaweed cultivation in deep waters has a positive impact on carrageenan yields in line with the increasing depths while the growth rate and the biomass production can be achieved higher at the lower depth.

Cultivation of red seaweed Kappaphycus alvarezii using the inverted pyramid method (IP) was carried out in the waters of Booi village, Saparua bay at the Central of Maluku regency. The effectiveness of the IP method can be compared with the conventional, longline (LL) method based on growth rate, biomass production and carrageenan yield. The IP method is operated on the surface layer of the deep waters to a depth of 10 meters, while the LL method is only operated in shallow waters at a depth of less than 10 meters. The results showed that growth and production of biomass with the IP method tended to decrease according to increasing depth, while the carrageenan yield increased. However, the carrageenan yield with the LL method increased in line with growth and production of biomass. It is seen that seaweed cultivation with the IP method is more effective than the LL method in terms of land area used, in addition to biomass production and the yield of carrageenan gained. ABSTRAK Budidaya rumput laut merah Kappaphycus alvarezii dengan metode piramida terbalik (PT) telah dilakukan di perairan Desa Booi, teluk Saparua di kabupaten Maluku Tengah. Efektivitas metode PT dapat dibandingkan dengan metode konvensional rawai datar (RD) berdasarkan laju pertumbuhan, produksi biomassa dan rendemen karaginan. Metode PT dioperasikan pada lapisan permukaan dari perairan dalam sampai kedalaman 10 meter, sedangkan metode RD hanya dioperasikan di perairan dangkal pada kedalaman kurang dari 10 meter. Hasil penelitian menunjukkan bahwa pertumbuhan dan produksi biomassa dengan metode PT cenderung berkurang sesuai dengan peningkatan kedalaman, sebaliknya rendemen karaginannya meningkat. Sementara rendemen karaginan dengan metode RD meningkat sejalan dengan pertumbuhan dan produksi biomassa. Terlihat bahwa budidaya rumput laut dengan metode PT lebih efektif dibandingkan metode RD dalam hal luas lahan yang digunakan, selain produksi biomassa dan rendemen karaginan yang diperoleh. Kata Kunci : Kappaphycus alvarezii, metode piramida terbalik, metode rawai datar, rendemen karaginan

Mud crab is one of the 12 aquaculture commodities of Ministry of Maritime Affairs and Fisheries. Control of reproduction to increase seed production through feed improvement, is one of the challenges and strategies in the mud crab aquaculture. Due to lack of knowledge about broodstock nutrition lead to producing rate of seeds still relatively low. This study aimed to obtain information on the kind of feed that has specific nutrient and plays a role in increasing the success of spawning and zoea survival. Mud crab of Scylla serrata with initial weight of 500.7±103.4 g, preferably under developed gonads were maintained in a fiber tank measuring length of 2.48 m, width 1.26 m, and a height of 60 cm which is partition sealed into 30×40×60 cm3 to put one crab. Tank was equipped with sand as a substrate as high as 15 cm and seawater system with flow rate of 1 L per six minutes and 25 cm high water. Treatments were consisted of: 1. PI (fresh meat fish of Decapterus sp. with dose of 5%), 2. PSC (fresh meat mixture of Decapterus sp. 1.8%, 3% of squid, and shrimp 1.2%), 3. PB (artificial feed dose of 10%) of BW, each treatment was repeated three times. Parameters measured were the duration of ovarian to mature, egg diameter, hatching rate, fecundity, and zoea production. Data were analyzed using ANOVA. The quality of larval measured by survival and larval fat and protein content. The results showed that crabs treated by PI and PSC showed faster to get mature compared to PB treatment (p<0.05). Hatching rate of larvae in PSC treatment was higher compared to PI and PB treatments (p<0.05). Furthermore, all treatments did not affect egg diameter, fecundity, and the number of zoea (p>0.05). In conclusion, crab which fed fresh meat (PI and PSC) could get mature earlier, and have high percentage of the larval hatching than those of fed by PB. In fact that larvae from broodstock feed of PI has survival as well as protein and fat content were higher than those of fed by PB.Keywords: spawning perform, broodstock feed, mud crab (Scylla serrata)

Mangrove crab is one of the leading export commodities and has high economic value. The increasing demand for mangrove crab exports has created new problems, namely the availability of seeds and the consumption size of this mangrove crab. Mangrove crab cultivation in Indonesia until now still depends on natural stocks, so it is necessary to review the development of sustainable mangrove crab cultivation. This community service activity was attended by 43 participants consisting of 6 teaching staff of the Department of Aquaculture, Faculty of Fisheries, Unpatti, and 37 people from Negeri Tuhaha. The stages carried out include delivering material on the types of mangrove crabs, direct introduction to the types of mangrove crab maintenance and enlargement containers, implementation of crab cultivation containers using the tancap and keramba methods, as well as discussions and questions and answers.

Marine debris in the waters has become a significant environmental issue, threatening the balance and function of coastal and marine ecosystems, including mangrove ecosystems. Poka Beach in the inner Ambon Bay is facing the accumulation of waste from local activities and external currents. To address this issue, the Community Service Program from the Faculty of Fisheries and Marine Sciences at Pattimura University organised a coastal cleanup and mangrove rehabilitation at Poka Beach, involving students, the community, and related institutions. This program aims to raise awareness about the threat of marine debris and the role of mangroves in the sustainability of coastal and marine environments and ecosystems. The Community Service activities include site surveys, coordination with relevant parties, beach clean-up actions, and replanting mangrove seedlings. This activity successfully collected various marine debris accumulated at Poka Beach, such as bottles, food packaging, and household items. Amounting 180 kg of plastic waste was sent to the waste bank for recycling. As many as 150 mangrove seedlings were planted at a distance of 1 meter along the 200-meter stretch of Poka Beach. The sustainability of similar programs through education, conservation, community empowerment, and cross-sector collaboration must be carried out to change community behaviour in proper plastic waste management and create cleaner and healthier coastal and marine environments.

Teluk Ambon, sebagai pusat aktivitas perikanan dan permukiman, kini menghadapi ancaman serius akibat akumulasi logam berat seperti timbal (Pb), kadmium (Cd), dan merkuri (Hg). Pencemaran ini bersumber dari aktivitas pertanian, industri, pertambangan, dan rumah tangga, serta berdampak buruk pada ekosistem laut dan kesehatan manusia, khususnya dalam konsumsi hasil laut. Dalam konteks ini, literasi lingkungan di kalangan pelajar menjadi penting untuk membangun kesadaran ekologis sejak dini. Kegiatan ini bertujuan untuk meningkatkan literasi dan kesadaran siswa SMA Negeri 3 Ambon terhadap bahaya cemaran logam berat di perairan Teluk Ambon. Kegiatan dilakukan melalui beberapa tahap, yaitu persiapan materi, sosialisasi, serta evaluasi pengetahuan siswa menggunakan pre-test dan post-test. Materi disampaikan secara interaktif melalui infografis, diskusi, dan studi kasus lokal yang relevan dengan kondisi sekitar. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman siswa; pemahaman terhadap definisi logam berat meningkat dari 43,3% menjadi 70%, dan pemahaman terhadap dampak lokal melonjak dari 3,3% menjadi 90%. Metode edukatif berbasis visual dan kontekstual ini terbukti efektif dalam membangun kesadaran siswa serta mendorong mereka menjadi komunikator lingkungan di komunitasnya. Kegiatan ini menunjukkan bahwa tanpa teknologi canggih, pendekatan transfer IPTEKS yang sederhana namun relevan dapat menjembatani dunia akademik dan masyarakat secara praktis. Transfer pengetahuan berbasis lokal dan visual terbukti efektif dalam meningkatkan kesadaran lingkungan siswa.

Mud crab (Scylla spp.) is one of the coastal fisheries resources that has important economic value. Along with the increasing market demand for mud crabs, the development of mud crab aquaculture is widely practiced in various coastal areas in Indonesia. The availability of local resource-based feed is one of the key factors for the efficiency of aquaculture efforts and the sustainability of mangrove crab aquaculture production in the region. This study aimed to examine the effect of a combination of unripe papaya fruit and fish flesh (Decapterus sp.) with different ratios on the growth of young mud crab cultured using the floating raft method in the Tuhaha Bay waters, Tuhaha Village, East Saparua District. A total of 12 mud crab were fed a mixture of papaya and fish at 10% per total body weight per day. Treatment A (5% papaya: 5% fish flesh) and treatment B (7.5% papaya: 2.5% fish flesh) were given to six individual mud crabs each. Weight measurements were taken weekly during the one-month study period. The results showed that young mud crab fed treatment B tended to have higher absolute weight growth rate and specific growth rate compared to juvenile mud crab fed treatment A but were not statistically significantly different. This finding explains that the composition of 25%-50% unripe papaya fruit combined with fish flesh (Decapterus sp.) effectively increases the growth rate of the mud crabs.

To optimise the production of microalgae culture, manipulation of media culture composition is one of the efforts. This study aimed to compare the growth of microalgae Pavlova sp. and the environmental culture conditions between different media compositions. Pavlova sp. was cultured for nine days using three different media compositions: A, B, and C. Cell density was counted daily. The concentration of ammonia, nitrate, and phosphate, as well as total Vibrio and total bacteria, were measured during the culture period on the 3rd, 6th, and 9th day. The result showed that the highest cell density was found in C media (5,08 x 106 cells/ml) followed by B media (4,58 x 106 cells/ml) and A media (4,46 x 106 cells/ml), but statistically, there was not significantly different growth rate between those media (P=0.83 >0.05). Phosphate and nitrate concentrations decreased in all media, but ammonia increased. The total count of bacteria and Vibrio sp. on C media was lower than on A and B media. This finding indicated that the composition of C media was more suitable for the growth and culture environmental condition of Pavlova sp. culture at a semi-massal scale.
