Abstract

Marine invertebrates are animals that have no vertebrae and are almost found throughout marine areas, including coastal areas such as coral reefs. The study aims to determine the diversity of invertebrate species associated with coral reefs in the waters of Palu Bay, Panau Village, Palu. The number of invertebrates found in coral reefs were 558 individuals in the day (22 families), while at night as many as 670 individuals (24 families). Family Pectinidae has the highest abundance, both in the day (50.17%) and night (41.79%) with the number of 280 individuals. The value of diversity index during the day ranged from 1.03 to 1.67, while at night the diversity index ranged from 1.72 to 1.81 and categorized as low. The homogeneity index during the day for all transects ranged from 0.27 to 0.40, while at night ranged from 0.31 to 0.34 categorized as the community under stress. The dominance index during day and night for all transects are categorized as low, which for daytime ranges from 0.21 to 0.39, whereas the night ranges from 0.24 to 0.28.

Abstract

Glyricidia sp. is a  considerable potential legumimous tree as a source of  goat feed. The leaves contain a  high protein, and expected to improve the reproductivity of livestock. This study examined the effect of Glyricidia leaves concentrat supplementation on local goat reproduction  in postpartum period.  Twelve 2 to 3 years old female local goats with average initial body weight of 23,08 ± 1,68 kg were used in this study.  The animal were placed randomly for  feeding, and  four replicate treatments were applied:  R0 = Concentrate 0% BW + Glyricidia spad-libitum; R1 = Concentrate 0.5% BW + Glyricidia sp ad-libitum; R2 =  Concentrate 1.0% BW + Glyricidia sp ad- libitum. The variables measured were dry matter intake (DMI), average daily gain (ADG), length of estrous, and pregnancy rate. The data of DMI, ADG, and length of estrous were analyzed using Completely Randomized Design (CRD) one way classification. If  significant differences among treatments occured, the Least Significant Difference (LSD) test was performed. The difference in pregnancy rate were analyzed using Chi-square. The results showed that the dry matter intake, average daily gain, length of estrous and pregnancy rate to female goats were significantly higher in concentrate supplementation of  0.5%  and 1.0% BW than without  concentrate supplementation. On the other hand,  between concentrate supplementation of 0.5% and 1.0% BW did not differ significantly. Keywords:Concentrate, Gliricidia sp, performance reproduction, postpartum period, local goat

Abstract

In vitro studies were exploring eleutherine (Eleutherine americana) potential to be used as feed additive for poultry.  The eleutherine bulbs were extracted using four different organic solvents: methanol, ethyl acetate, diethyl ether and hexane.  The crude extracts were analyzed for their bioactive compounds, tested for anioxidant and antibacterial activity and tested for growth of non-pathogen bacteria. The results indicated that bioactives are indentified:phenol and tannin. Average of antioxidant activity were 33.74, 20.36, 15.14 and 1.98 ppm AEAC  for methanol, ethylacetate, diethylether and hexane, respectively. Furthermore, average of inhibition growth for  pathogen bacteria of Escherichia coli was 5.94, 4.75, 4.56 and 4.44  mm  for  methanol, ethylacetate, diethylether and hexane, respectively, while inhibition for  Staphylococcus aureus was 5.37, 6.50, 5.37 and 5.18  mm for  methanol, ethylacetate, diethylether and hexane, respectively. The extracts also have ability to enhance the gorwth of non-pathogen bacteria Lactobacillus acidophilus. Average of bacteria growth improvement was 21.12, 28.57, 28.16 and 19.59 NTU for methanol, ethylacetate, diethylether and hexane, respectively. The presence of antioxidant and antibacterial activity and growth enhancer activity could be attributed to the bioactive and non digested carbohydrate content of the bulbs extracts.  Therefore, it  could be concluded that the bulbs of eleutherine extract is potential source for “feed additive” as phytobiotics as well as prebiotics.Key words: Eleutherine, Extract, Bioactive, Phytobiotics, Prebiotics

Abstract

Xenopoecilus sarasinorum is an endemic fish from Lake Lindu; its existence is not widely known. The fish is listed as an endangered fish according to IUCN 1996. One of efforts to conserve the fish is domestication. This study was asmed to determine the growth of X. sarasinorum domesticated with different types of feed. The research was conducted from December 2012 until February 2013 in the Laboratory of Aquaculture, Faculty of Animal Husbandry and Fisheries, Tadulako University Palu. This study used a completely randomized design consisting of three treatments i.e. treatment A (silk worms feeding), treatment B (mosquito larvae feeding), treatment C (blood worms feeding) and six experimental replicates so that there were 18 experimental units. The results showed that the best feed for X. sarasinorum growth was silk worms. The absolute weight gained by the fish wich given silk worms was  0,330 g. Based on the results of analysis of variance (ANOVA) provision of different types of feed that gives a very real effect on the growth of fish biomass X. sarasinorum (P <0,01). Key words : Domestication, endemic fish, Lake Lindu, Xenopoecilus sarasinorum.

Abstract

One strategis to provide feed in developing rabbits in the dry areas is utilising forage that are able to survive in during dry season. This experiment was aimed to examine the use of different forages on water intake, feed intake and digestibility of local rabbit. The experiment employed  20 male local rabbits, consentrate feed 2% of live weight and forage ad libitum, metabolisme cages and also supporting equipments. The experiment design used was randomised block design, which consisted of 4 treatments and 5 replicates. The dietary treatments were P1 (MO) = Moringa oleifera, P2 (LL)= Leucaena leucocephala, P3 (DV)= Desmanthus virgatus, and P4 (TI)= Tamarindus indica.The result showed that  different forage affected very significantly (P<0.01) feed intake. However, treatment did not affect significantly (P>0,05) water intake and feed digestibility of local rabbit. It was concluded the best forage for local rabbit is Desmanthus virgatus.Key words: Drink water, Digestibility, Consumption, Forage, Local rabbit

Abstract

Mangrove ecosystem is vegetation community in tropical coastal area that dominated by various mangrove trees which are having high ability to grow in mud tidal coast. The objective of this research is to assess mangrove species composition in the coastal area of Labuan, Lage, Poso District. The research was conducted from October to December 2011 using line transect with strip sampling applied across topographical contours. The results of the study showed that Rhizophora apiculate has the highest important value index (IVI) for tree level, sapling, seedling with value     of 97.3%, 105%, 75%, respectively. With similar calculation, it was recorded that Bruguire gymnorrhiza has the lowest IVI with value of 41.5%, 31%, and 24%, respectively.Key words: Coastal area, composition, mangrove, vegetation.

Abstract

This research aimed to identify factors threatening the population and migration of leatherback turtles, analyze community perceptions (stakeholders) from ecological, economic, cultural, legal and institutional aspects, formulate policy strategy of management and development of leatherback turtle conservation area on the Wermon Coast of Tambraw Regency. Data collection techniques used were literature study and field studies through interviews, observation and documentation. Sampling was conducted by purposive sampling method with the number of respondents of 50 persons. The results showed that several factors that threatened the population and migration of leatherback turtles were sand temperature and temperature variations, sea level rise, beach slope, and sand texture. Community perception of ecological aspects showed 80% positive habits, economic aspect increased local people's income, cultural aspect showed 90% of respondents accept, legal and institutional perceptions showed 94% of people support spatial planning policies and 86% social institutions support the development of conservation areas. Several SWOT analysis strategies for developing leatherback turtle conservation area, namely provide training for management of leatherback turtle conservation, create a community-based turtle conservation management manuals, improve facilities and infrastructure, increase monitoring of coral reef resources, implements strict control of pollution materials that can disrupt the living conditions of leatherback turtles, increase public understanding of conservation areas and promote the role of the leatherback turtle in the community.Keywords: Conservation area, leatherback turtle, SWOT analysis.
