Title (Bahasa Indonesia): Analisis pertumbuhan dan kualitas karagenan rumput lautÂ Kappaphycus alvareziiÂ pada lokasi berbeda di Wilayah Perairan Banggai ProvinsiSulawesi TengahÂ Seaweed is a potential of coastal resources. Carrageenan is a polysaccharide extracted from seaweed or some species of red algae (Rhodophyceae). Seaweed growth is strongly influenced by two factors: internal and external factors. ButÂ twthat determine the success of theÂ seaweedÂ growthÂ is the management carried out by people working on it. BanggaiÂ Regency is one of the largest seaweed production centers in Central Sulawesi. The main objective of this studyis toexamine the potential of seaweed cultivation (Kappaphycus avarezii) by looking at the growth andÂ theÂ carrageenan, inBanggai waters, Central SulawesiProvince. The temperature range obtained during this studyÂ r25toÂ 31ÂºC. The results of carrageenananaliysis wasvery differentÂ due to differences inlocation, showed by content.Â Â The highest and lowest ashcontentwere obtained from two locations,Â 1,8% (Jayabakti) and 2.8% (Liang), respectively.Rumput laut merupakan sumberdaya pesisir yang sangat potensial. Karagenan merupakan polisakarida yang diekstraksi dari beberapa spesies rumput laut atau alga merah (rhodophyceae). Pertumbuhan rumput laut sangat dipengaruhi oleh dua faktor yaitu faktor internal dan faktor eksternal. Namun yang sangat menentukan keberhasilan pertumbuhan rumput laut yaitu pengelolaan yang dilakukan oleh manusia. Kabupaten Banggai merupakan salah satu sentral produksi rumput laut terbesar di Sulawesi Tengah. Tujuan utama penelitian ini mengkaji tentang potensi budidaya rumput laut (Kappaphycus alvarezii) yang dikembangkan dengan melihat pertumbuhan dan analisis karaginannya di perairan Kabupaten Banggai Provinsi Sulawesi Tengah. Kisaran suhu yang didapat selama penelitian ini adalah berkisar 25â€“31ÂºC. Hasil analisa rendemen karagenan ini sangat berbeda yang disebabkan oleh perbedaan lokasi memberikan pengaruh nyata terhadap kandungannya. Nilai kadar abu tertinggi dan terendah berturut-turut yang di peroleh dari kedua lokasi ini adalah 1,8% (Jaya Bakti) dan 2,8% (Liang).

Crustacean larvae have the characteristics of living as carnivorous organisms. This has an impact on the length of gut evacuation time which affects the feeding pattern of the larvae. The feeding strategy of mud crab larvae is modulated by the length of gut evacuation time. Another factor that can be subject to modulation is the frequency of feeding. This research aimed to evaluate rotifer frequency feeding of early larvae stages of mud crab, Scylla olivacea. This research was conducted at the Mariculture Fisheries Center, Ambon with an indoor system. This research began with carrying out parental maintenance to produce larvae. Larvae are fed with rotifers with different frequencies. The treatments were the frequency of feeding rotifers, namely: Treatment 1 (F1) was the frequency of 1x a day (9:00 am); Treatment 2 (F2) was a frequency of 2x a day (9:00 am & 13:00 pm) and Treatment 3 (F3) was a frequency of 3x a day (9:00am, 13:00pm & 17:00pm). Each treatment was given 3 replications. Based on the results of this study, it showed that feeding with a frequency of three times a day (F3 treatment) was able to have a positive effect on the survival rate of zoea larvae which on the third day was 58% and the fourth day was 22% higher than the F1 and F2 treatments. The growth of larvae showed that F3 treatment was higher than F1 and F2 on the sixth day with an increase in the absolute value of growth of 0.12044 mm compared to F1 of 0.05531 mm and F2 of 0.03253 mm.Â Keywords: frequency of feeding, growth, larvae, survival rate, mud crab

Vannamei shrimp (Litopenaeus vannamei) is a brackish water commodity that is currently in great demand and is a leading producer of the aquaculture sector in Indonesia. This is because some of the advantages possessed by the vannamei shrimp, among others, can be maintained with a high stocking density, rapid growth, has a high resistance to disease and environmental changes. The mating process occurs through four stages, namely approach, pursuit, pride, and mating. This process can be known by looking at the behavior of the male parent who swims to follow the female parent. They both looked like a chase. Then the male parent swims parallel to the female and turns her body towards the female shrimp's belly. After that, the male grabs the female and releases sperm that attach to the thellycum. In the maintenance of larvae that must be considered is the management of water quality and feed management. This is because water is a living medium for aquatic organisms, so it determines the survival of larvae. During the period of high maintenance and market, demand continues to increase where the shrimp farming process includes the hatchery stage to enlargement. Vannamei shrimp hatchery activities are inseparable from the availability of quality fry

This study aimed to assess the quality of seaweed by analyzing its carrageenan content, water content, and growth rate. The research was conducted in the waters of Liang Village and Jayabakti Village for 45 days, with observation periods every 15 days. Carrageenan examination was carried out at the Pharmacy Laboratory of Sam Ratulangi University, while the water content was determined at the THP Laboratory of the same university. Growth measurements were conducted at 0, 15, 30, and 45 days in both locations. The results showed that the concentration of carrageenan in seaweed from Jayabakti Village was 39.81%, while in Liang Village it was 35.88%. The percentage of seaweed water in Liang Village was 9.3%, while in Jayabakti it was 27.0%. In addition, there was no significant difference in seaweed growth between the two water sites (P>0.05). The average difference in seaweed growth between Jayabakti Village and Liang Village on days 15, 30, and 45 was 1.5, 0.5, and 16.3, respectively. The daily weight gain rate of seaweed on day 15 was 5.55% in Jayabakti Village Waters and 5.50% in Liang Village Waters. On the 30th day, the daily weight gain of seaweed in Jayabakti Village Waters and Liang Village was 4.88% and 4.89%, respectively. On the 45th day of the rearing period, seaweed in Jayabakti Village Waters experienced a weight gain of 4.16%, while seaweed in Liang Village experienced a weight gain of 4.22%. The findings showed that the carrageenan test, conducted by assessing water content, indicated that the quality of seaweed in the waters of Liang Village was superior to that of Jayabakti Village.
