Abstract

Palm kernel meal (PKM) is the potential of raw material for feed fish ingredient because it has good nutritional content and abundant availability in Indonesia. The study was conducted to evaluate of PKM fermented as feedstuffs as well as the effect on feed digestibility of tilapia. This research consisted of 2 trials: the the test of S. cerevisiae fermentation on PKM and digestibility test of PKM as feedstuffs. The first trial used a factorial randomized design consisting of 2 factors: S. cerevisiae dose (0; 0.9; 1.5%) and incubation time (0, 24, 48 hours) with 3 replications. The second trial used a completely randomized design consisting of 3 treatment of test feed, namely A: reference feed, B: reference feed + PKM, C: reference feed + PKM fermented and 4 replications. Fish (initial weight: 5.34 ± 0.14 g) were reared in an aquarium for 40 days with a recirculation system. The results showed that the fermented of 1.5% S. cerevisiae and time incubation for 24 hours recorded the lowest crude fiber content (8.86 ± 0.51%). The highest total digestibility value (P <0.05) was found in treatment A (45.36 ± 2.17%) and C (46.61 ± 2.36%) compared to treatment B (38.46 ± 1, 07%). The highest protein digestibility value significantly (P <0.05) was found in treatments A and C (72.89 ± 4.57%, 74.27±1.26%, respectively) than treatment B (58.70 ± 3.57%). Finally, it can be concluded that the fermentation of PKM by S. cerevisiae can be used as feedstuffs for tilapia feed.

Abstract

Moringa leaves is a potential ingredient for raw material of tilapia feed, which a high protein content of 25%. However, moringa leaves has a high fibre and antinutritional factors. The aims of this study was to evaluate the fermentation of Moringa leaves (Moringa oleifera) as a raw material feed on tilapia (Oreochromis niloticus). This study was conducted for eight months at Laboratory of Aquaculture, Department of Fisheries, Faculty of Agriculture, University of Sultan Ageng Tirtayasa. The study consisted of 4 treatments of feed with different fermentations, namely: A: reference feed 70% + Moringa leaves meal 30%, B: reference feed 70%+fermented Moringa leaves meal with Rhizopus oligosporus 30%, C: reference feed 70%+fermented Moringa leaves meal with Saccharomyces cereviceae 30%, and feed D: reference feed 70%+fermented Moringa leaves meal with Aspergillus niger 30%. The results showed that feed with Moringa leaves fermentation using A. niger resulted in the best growth on tilapia compared to other treatments. Fermentation with A. niger and R. oligosporus on Moringa leaves produced the best nutrient digestibility value compared to other treatments. Moringa leaves fermented with A. niger, S. cerevisiae and R. oligosporus had no effect on physiological processes on tilapia, as shown by hematological parameter values that were within the normal range. Moringa leaves fermented with Aspergillus niger can be used as a raw material for tilapia feed.

Abstract

The current marine environment has begun to be polluted and will directly affect the biota around it. The study of health conditions and spatial variations in the characteristics of the population of Rhizophora apiculata was carried out in the mangrove ecosystem around the oil and non-industrial areas of Riau Province. This study aims at a baseline for evaluating mangrove management in Riau Province. Sampling is carried out using line transects drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland and sample plots made with a size of 10 X 10 m2. Samples of leaves, fruits, and flowers are taken randomly based on the sample plots made. Then preserved with 70% alcohol and labeled. The preserved samples were taken to the laboratory to measure morphometrics and calculate the number of stomats. The results showed that the population of R. apiculata at all stations was in an unhealthy condition. In addition, individual competition and adaptability possessed by the population of R. apiculata are very low, ranging from 09.53 - 17.27% and illustrating more group growth and very high competition among individuals. Furthermore, the discriminant analysis shows that the morphometric variables that most characterize the population of R. apiculata in the oil industry with non-industrial areas are the length of the stem. Based on the results of PCA analysis, the variables that most determine the poor health of the population of R. apiculata are the parameters of Pb heavy metals, pH, temperature and DO waters.

Abstract

Tilapia (Oreochromis niloticus) is one freshwater fish which have high economic value. In the culture of tilapia, feed is the most important external factors. The optimal levels of protein to support the growth of tilapia ranged from 28-40 %, however the digested one is only about 20-25 % and the others were wasted and accumulated in the water. An attempt have been done to improve the feed digestibility value in tilapia by using the prebiotics addition to the feed. The aims of this research was to evaluate the addition of prebiotics to the feed to improve feed digestibility value in tilapia. The parameters measured were the amount of feed intake, the total population of bacteria, protein digestibility, fat digestibility, total digestibility, protein retention, fatty retention, specific growth rate, survival rate and feed efficiency. The results showed that the protein digestibility was 92.25%, fatty digestibility was 96.61% and total digestibility was 86.77%. The best results of feed was found in the addition of 1% prebiotic.Keyword: digestibility, prebiotics, tilapia
