Abstract

Krustasea merupakan organisme laut dengan keunikan tersendiri, karena visualisasinya yang beraneka warna dan dalam daur hidupnya organisme ini dapat berganti kulit. Kekhasan warna yang dimiliki oleh krustasea juga menarik perhatian pada saat dimasak yakni berubah warna menjadi merah. Fenomena ini terjadi karena adanya zat warna yang dikandung oleh krustasea dan dikenal sebagai pigmen karotenoid.  Pada umumnya organisme laut termaksud krustasea memiliki kandungan pigmen karotenoid dengan jenis dan tipe yang beragam. Pigmen karotenoid merupakan pewarna alami (biokrom) yang umumnya terdapat pada krustasea. Pada penelitian-penelitian sebelumnya menunjukkan bahwa penentuan jenis pigmen dapat dilakukan dengan menggunakan metode Kromatografi Lapis Tipis (KLT). KLT merupakan cara cepat dan mudah untuk pemisahan senyawa pada suatu sampel berdasarkan polaritas. Metode ini memudahkan untuk analisis skala kecil karena hanya memerlukan bahan-bahan yang relatif sedikit dan juga waktu yang cukup singkat, maka dari itu untuk mengetahui distribusi pigmen karotenoid pada kepiting Grapsus sp dalam penelitian ini menggunakan metode KLT. Hasil yang diperoleh dari penelitian ini ditemukan bahwa distribusi  pigmen karotenoid pada kepiting Grapsus sp betina adalah  jenis pigmen β–karoten,  β-kriptoksantin, astaksantin dan pigmen tipe  astasen, yang terdistribusi pada organ karapas, lapisan epidermis, hepatopankreas dan gonad dari kepiting Grapsus sp.

Abstract

The objective of this study was to determine the growth of seaweed Kappaphycus alvarezii cultivated with Eucheuma denticulatum with different composition. This research was carried out for six weeks, from March to April 2013, in the coastal waters of Sondaken village, Tatapaan District, South Minahasa regency, North Sulawesi. The experiment was designed according to completely randomized design with four treatments and three replications. The four tested treatments were the different composistion of tied seaweed in a long-line raft, where treatment A: 100% K. alvarezii, ; B: 50% K. alvarezii and 50% E. denticulatum, on each culture line, two types of algae were tied in sequence; C: 75% K. alvarezii and 25% E. denticulatum, in which in each line, every three bunch of K. alvarezii was followed by one bunch of E. denticulatum; D: 25% of K. alvarezii and 75% E. denticulatum, on each culture line, every three bunch of E. denticulatum was followed by one bunch of K. alvarezii. Each experimental unit was a 3m x 3,4m rectangular line raft containing four culture lines where the bunch of the tested seaweed were tied. Data collection was performed every two weeks by weighing the tested K alvarezii. The data were statistically analyzed (ANOVA) using JMP statistical program (SAS-institute). The results showed that absolut growth, relative growth and daily growth rate of K. alvarezii was not significantly affected by the tested treatments (Prob> F > 0.5). Thus, the occurence of E. denticulatum in whatever abundance in K. alvarezii cultivation area will not affect the growth of K. alvarezii. Keywords: Seaweed, K. alvarezii, E. denticulatum, growth

Abstract

This study aimed to determine the effect of providing a combination of natural feed maggots and pellets on the growth performance of Nile Tilapia and to ratio between maggots and pellets that promote growth of Nile Tilapia. The research was conducted from June to August 2020. The research method was using a completely randomized design (CRD) with 5 treatments and 3 replications with the following treatments: treatment A = 100% pellets, treatment B = 75% pellets and 25% maggots, treatment C = 50% pellets and 50% maggot, treatment D = 25% pellets and 75% maggot, treatment E = 100% maggot. The test fish used Nile Tilapia fingerling with average weighing 4 g / fish with density of 5 fish / container and maintained for 21 days. The containers used in this study were 15 plastic trays with a diameter of 40 cm and a height of 20 cm each with a water capacity of 15 liters. Growth performance data were Weight gain (WG), Specific growth rate (SGR), relative growth rate (SGR), feed convertion rate (FCR) and feed intake (FI). Based on the results of this study, it shows that the use of a combination of pellet and maggot feed as Nile tilapia juvenile has an effect on the growth performance of Nile tilapia so that maggot can be used as an alternative feed that has high nutritional content for tilapia fish cultivation. The treatment that gave the best growth effect on tilapia seeds was found at the dose of a combination of 50% pellet feed + 50% maggot, with Weight gain (5.5±1.1g), SGR (3.7±0.5%), RGR (139.4±53.4) and FCR (1.2±0.2)

Abstract

This study aimed to examine the effect of several types of natural substances in increasing the growth of tilapia optimally. The fish were taken from Board of Fisheries and Freshwater Aquaculture Tatelu (BPBAT), North Sulawesi Province. Fish were acclimatized for a week in ponds in the “mina padi” system, with a density of 25 fish/net. After acclimatization, the fish were fed pellet with the addition of ginger (Zingiber officinale), garlic (Allium sativum Linn), and yeast (Saccharomyces cerevisiae) for 30 days as much as 10% /fish body weight /day with the frequency of feeding twice a day, namely at 08.00 and 16.00. This study used a completely randomized design (CRD) with four treatments, namely treatment A: ginger flour 7.5 g/kg of feed, treatment B: garlic flour 15 g/kg of feed, treatment C: Yeast 5 g/kg of feed and treatment D: commercial feed (control), each had three replications. The weight of fish was scaled weekly. The results showed that the growth of fish fed with the addition of baker’s yeast was better than fish fed with the addition of ginger, garlic, and commercial feed, but statistically the growth of fish fed with baker’s yeast and ginger were not significantly different from each other.

Abstract

This study aimed to find out the right extraction method to produce ketapang leaf extract with best phytochemical content and best inhibition ability against ice-ice causing bacteria. The experiment was conducted at the Laboratory of Fish Health, Environmental and Toxicology, from April to June, 2021. The experiment was designed according to a Completely Randomized Design (CRD) with 5 treatments and 3 replications. The three main treatments were, treatment A: extraction of ketapang leaves Terminalia catappa L. with 95% ethanol (extract A), treatment B: extraction of ketapang leaves T. catappa L. with 40°C water (extract B), and treatment C, extraction of ketapang leaves T. catappa L. with distilled water (extract C).  In the inhibition ability test, each extract obtained from the three main treatments was compared with two controls namely treatment D: positive control (Kanamicyn) and treatment E: negative control (aquadest). The phytochemical content data was analyzed descriptively, while the bacterial inhibition zone diameter data was statistically analyzed with Anova and LSD. The phytochemical analysis result showed that, the extract A contains alkaloids, flavonoids, triterpenoids and tannins,  while extract B and extract C contain alkaloid, saponin and tannin. The inhibition ability test showed that extract A gave the strongest inhibition (14.87 mm) against the ice-ice causing bacteria, and was significantly different from that of extract B (5.23 mm) and C (2.47 mm).  The inhibition ability of extract B was significantly different from that of extract C. The inhibition ability of the three ketapang leaf extracts (A, B and C) against the ice-ice causing bacteria was much weaker and significantly different from that of Kanamicyn (positive control).
