Abstract

The research aimed to sex ratio and size at first maturity of snakehead gudgeon at Bolano Sau Lake. The research was conducted at Bolano Sau Lake from August to December 2019. Snakehead gudgeon samples were obtained from the fishermen using a gillnet with a mesh size 2½-3½ inches. Sample analysis was carried out at the Water Quality Laboratory, State College of Fisheries and Marine, Palu. The difference in sex ratios of snakehead gudgeon used the Chi-square test, while the size at first maturity was estimated based on the Spearman - Karber method. Snakehead gudgeon caught on a gillnet in Bolano Sau Lake measuring 79-163 mm. The sex ratio between males and females is not balanced where males are more dominant in females. The size at first maturity was 119.19 mm. Suggestion minimum legal size > 120 mm. The use of gillnets in snakehead gudgeon fishing activities has an effect on the balance of male and females, but is very selective with size.

Abstract

This study aims to identify the potential and analyze the patterns of utilization of coral reefs in Bontosua Island, Pangkep Regency. The method used is the method of observation and in-depth interviews with a questionnaire that identifies the condition and use of coral reefs and calculates the value of use as a fish producer and as a tourist spot during. The results obtained indicate that the fact that the coral reefs on the island of Bontosua reach 80% with the economic value of direct coral reef benefits of Rp. 200,400,000 and an indirect economic value of Rp. 4,735,000,000. The conclusion of this research is that the economic value of the direct benefits of coral reefs on Bontosua Island is still very small, namely 4% while the value of indirect benefits reaches 95.9%.

Abstract

Turkey is a type of poultry from the order Galliformes, the genus Meleaagriss which is starting to get public attention for cultivation. The cultivation of turkey in Indonesia is still lacking, most of the breeders prefer other types of poultry. Turkey is a type of poultry that has the potential to be developed as a meat animal, because it has a large body size and is able to utilize feed ingredients in the form of grains and forage. This study aims to determine the growth of male turkeys aged 19-25 weeks at different energy levels. The research was carried out in the experimental cage of the Faculty of Animal Husbandry and Fisheries in South Sibalaya Village, Tanambulava District, Sigi Regency, on June 24 - July 29 2018. The study used a completely randomized design (CRD) with 3 treatments and 5 replications. The treatments are R1 = Rations with Metabolic Energy of 2800 Kcal/Kg, R2 = Rations with Metabolic Energy of 2900 Kcal/Kg, R3 = Rations with Metabolic Energy of 3000 Kcal/kg. The variables observed were rations consumption, body weight gain and rations conversion. The results showed that the treatment had a significant effect (P <0.05) on rations consumption, had no significant effect (P> 0.05) to increase of body weight and rations conversion. Using energy levels of 3000 Kcal/Kg gives a positive result on rations consumption for male turkeys aged 19-25 weeks.

Abstract

This study aims to determine the comparison of the use of bread waste and milled corn as a source of energy in concentrate to the weight and percentage of external non-carcass components of female local goats. This research was conducted from January 1 - April 23, 2020 at CV. Prima Breed, Tondo Village, Mantikulore District, Palu City, Central Sulawesi. The number of livestock used in this study was 12 female local goats aged ± 10 months with a weight range of      10-12 kg. The study used a two-treatment comparison test with t-test statistical analysis. The treatments in this study were: P1 = Giving concentrate with the basic ingredient of an energy source is milled corn + Panicum sarmentosum Roxburg (Roxb) ad-libitum and P2 = Provision of concentrate with the basic ingredient of energy sources is bread waste + Panicum sarmentosum Roxburg (Roxb) ad-libitum . The results of the t-test statistical analysis showed that the provision of concentrate + bread waste + milled corn gave a significant difference to the percentage of the external non-carcass components of local goats, while the provision of concentrate + bread and the provision of concentrate + ground corn did not give a significant difference to the weight of the non-carcass components external local goats.

Abstract

The research aimed to determine the effect of adding curcuma extract (Curcuma xanthorrhiza) to commercial feed on the growth and survival rate of tilapia (Oreochromis niloticus) seeds. Sample organism used in the study was 200 tilapia seeds with an average weight of 1.55 grams, obtained from BBI Tulo, Dolo District, Sigi Regency. This study used a completely randomized design (CRD) consisting of four treatments with five replications. Treatment A: without addition curcuma extract; Treatment B: addition curcuma extract 4 g/kg of feed; Treatment C: addition curcuma extract 8 g/kg of feed; Treatment D: addition curcuma extract 12 g/kg of feed. The prepared curcuma extract is then put into a spray bottle according to the predetermined dose. The biomass and weight of the sample organisms were pondered at the beginning and the end of maintenance period. Measurement of water quality includes temperature, pH, dissolve oxygen and ammonia. The results showed that the treatment had a significant effect (p <0.05) on the absolute weight of tilapia seeds. The highest percentage of absolute weight and survival rate in tilapia seeds was obtained in treatment D of 1.423 g and 94%, respectively.

Abstract

This study aims to determine the ratio of weight and carcass percentage of local goats that are given and not given Java wood hay. The research material was 12 female Kacang goats aged 10 months. The study used a comparative test method between two treatments, each of which was repeated 6 times. The treatments of the research were P1 = Giving concentration of 1.0% BK from BB without leaves of Java wood and P2 = Giving concentration of 1.0% BK from BB + hay from Java wood leaves 0.5% BK from BW. The results showed that the carcass weight of the bean goat carcass (P1 = 7.02 and P2 = 7.35) which were given the concentrate without the leaves of Javanese wood (P1) and those which were given the concentrate + hay of the leaves of the Java wood and (P2) were not significantly different (P> 0.05). . The percentage of peanut goat carcass (P1 = 46.60 and P2 = 48.26) showed that the provision of concentrate without hay of Java wood leaves was significantly lower than the percentage of carcass of peanut goat carcass which was given concentrate + hay of Java wood leaves at the 95% confidence level.
