Abstract

Cassava peel meal (CPM) has potential as a raw material for fish feed due to its abundant availability and good nutritional content. The high crude fiber content inhibits the use of CPM as a raw material for fish feed. Therefore, this study aims to evaluate the effect of Aspergillus niger fermentation of CPM on dietary nutrient digestibility and growth performance of tilapia (Oreochromis niloticus). It was conducted in 2 stages. The first stage was a fermentation process of CPM, which used a factorial randomized design consisting of a dose difference of A. niger, namely 10, 15, 20, 30 g.kg-1 and a fermentation time of 0, 12, 24 hours with 3 replications each. At a dose of 1.5% of A. niger during 24 hours of fermentation, the crude fiber content of fermented CPM was reduced up to 7.19%. the second stage was a 45 days feeding trial on tilapia used a completely randomized design consisting of 3 different treatments with 3 replications, namely: reference feed, unfermented cassava peal meal based diet (CPMD), and A. niger fermented CPMD. A. niger fermented CPMD showed an increase in growth, dry matter, protein, energy, and raw material digestibility, as well as daily growth rate compared to unfermented CPMD. The daily growth rate of fermented CPMD of 1.32%/day was significantly higher with P0.05 than the unfermented CPMD of 0.72%/day. Furthermore, the digestibility value of material test in the fermented CPMD (48.73%) was significantly higher (P0.05) than unfermented CPMD (11.74%). These results indicate that A. niger fermented CPM has the potential to be used as raw material for tilapia fish feed. Keywords:Aspergillus nigerFermentationTilapiaCrude fiber

Abstract

The active operation of a trammel net by a sweeping technique is commonly used by fishermen in Cilacap, which are often referred as ciker nets. They are operated by lowering the net in a straight line and pulling the tail end from a ship moving in a full circle, while the other end functions as a circular axis. The effect of active operation allows for changes in performance with time, such as easy lifting or less buoyancy, and the unstable display of gears. This makes it necessary to perform design engineering, especially on buoys, sinkers, and high nets. However, the suitable quantity of these components for ciker net has never been ascertained. Calculations about how many buoys, sinkers, and net height to add need to be done to enhance ciker net construction for active operation. This research aimed to determine the optimum configuration of buoys, sinkers, and net height, and determine the engineering design of ciker nets based on the optimum ratio of buoyancy force to the sinking force of the trammel net. Therefore, the parameters measured include hanging ratio, stretched net length, buoyancy force, and sinking force. The results showed that the optimum configuration of buoys, sinkers, and net height was 59 pieces, 341 pieces, and 1.5 m respectively. Changes in the design of ciker nets, especially in the three components that affect the addition of buoyancy and sinking force ratio were based on the comparison of the trammel nets which was 1:5 greater than the design owned by fishermen at 1:4.Keywords:Bouyancy forceSinking forceCiker netTrammel netShrimp

Abstract. Rubber seed Hevea brasiliensis contains relatively high oil and potentially used in a diet as sources of fatty acid  and  energy  as  well.  A  study,  therefore,  was  conducted  in  the  aim  of  evaluating  the  use  of  rubber  seed  oil  as  a substitution  of  soybean  oil  in  the  diet  for  increasing  growth  performance  of  common  carp.  The  treatments  were  the substitution of rubber seed oil to soybean oil at a respectived level of 0, 25, 50, 75 and 100%, each treatment had three replications. Test diet contained Cr2O3 as digestibility indicator. After acclimatization, common carp fingerling of 3.55 ± 0.00 g in average weight was randomly stocked in 15 aquaria of 69x29x35 cm3 in dimension size containing 50 L water  at  15  fingerlings  per  aquarium  and  fed  iso-protein  and  iso-energy  test  diet  at  satiation  for  40  days  of  the experimental period. Feces in each tank were collected at day 3 for 15 days. Parameters tested were digestibilities of total and fat, diet consumption, growth, protein/fat retention, and survival. The results showed that the more increase rate of substitution  of  rubber  seed  oil  in  the  diet,  the  more  significantly  declining  diet  digestibility  and  growth  performance  of common carp (P0.05). It is concluded that the substitution of rubber seed oil to soybean oil as much as 25% in diet resulted in the highest diet digestibility and growth performance of common carp.Keywords: Common carp, Digestibility, Rubber Seed Oil, Soybean Oil, Growth Performance Abstrak.  Biji  karet Hevea brasiliensi  mengandung lemak  relatif  tinggi  dan berpotensi  digunakan  dalam pakan  ikan  sebagai sumber  asam lemak  dan  energi.

Abstract

Functional food is a food ingredient in addition to basic needs as nutrients that can also play a functional role in health. This research aimed to determine the physicochemical characteristics and fatty acid composition of catfish oil, red palm oil, and shark liver oil as functional food ingredients. The research method was to extract fish oil from belly flap, purify catfish oil, and process red palm oil (RPO) from crude palm oil (CPO). The analysis parameters consisted of sensory analysis, oil chemical characteristics (free fatty acid analysis, peroxide, iodine, saponification, and acid numbers), total carotene, tocopherol, and analysis of fatty acid composition. The results showed that the catfish oil after being purified had sensory characteristics, smelled slightly fishy and semi-solid, and had a bright yellow color. The results of the analysis of chemical characteristics showed that the free fatty acid numbers of catfish oil and shark liver oil were following IFOS standards (1.33 and 0.62%), and the RPO numbers for peroxide and free fatty acids according to the SNI standards (9.56 meq kg and 1.44%). The highest ω-3 and ω- 6 fatty acids were in shark liver oil (3.56 and 35.35%), followed by catfish oil (1.72 and 19.9%). and RPO does not contain ω-3 and ω-6. Catfish oil, RPO, and shark liver oil act as functional foods. The fatty acid composition of catfish, shark liver and red palm oil contains saturated and the fatty acid composition of catfish, shark liver and red palm oil contains saturated and unsaturated fatty acids. Mono and poly unsaturated fatty acid (FUFA anf MUFA) in crude catfish oil, pure catfish oil, shark liver oil, and red palm oils were 56.71, 58.12, 63.81 and 47.39% respectively. The result of analysis showed composition of in catfish oil 1.72 and 19.9 %. The content of and of shark liver oil was 3.5 and 35.5%.  Whereas in red palm oil does not Ω 3 and Ω 6. The content of EPA and DHA in shark liver oil was 0.08, 0.09 but not in catfish and red palm oil. The total content of carotene and tocopherol in red palm oil was 513.86 and 925.80 mg/kg, respectively. The nutritional composition of catfish oil, red palm oil, and shark liver oil has the potential to be used as functional food. Keywords:Characteristic physicochemicalCaroteneTocopherolω-3ω-6

Abstract

White snapper Lates calcarifer is one of the marine fish commodities that has important economic value. The addition of immunostimulant ingredients in feed is believed to increase immunity and increase fish growth. This study aims to determine the effect of adding β-glucan to feed on white snapper (Lates calcarifer). This study used a completely randomized design (CRD) consisting of 5 treatments with 3 repetitions. White snapper used with a weight of ± 6 grams and a length of ± 7. The frequency of feeding is done 3 times a day. The results of the ANOVA test showed that the addition of β-glucan in the feed significantly affected the growth rate of the fry of white snapper (Lates calcarifer) (P0.05). The best treatment in this study was treatment E (commercial feed + β-glucan 8g/kg feed) which gave the best growth in White snapper where this treatment was able to increase absolute weight (4.51 ± 0.29), absolute length (4 .84 ± 0.284), specific growth rate (2.09 ± 0.15), FCR (1.00 ± 1.00), feed utilization efficiency (97.42 ± 0.50) and survival (100.00 ± 0.00).
