Abstract

The purpose of the research was to identify the highest production of Gracilaria verrucosa cultivated in a sea-fish pond with different seed weights and different plantation intervals.           The research hipothesis was that there was an interaction between different seed weight and planting interval on Gracilaria  verrucosa production. The research was done for 50 days. This research used a Completely Randomized Design in a Two Factorial Experiment with three replicates. The first factor was seed weights: 50 g, 100 g and 150 g. The second factors was plantation intervals included 10 cm, 20 cm, and 30 cm ntervals. The measured parameter was production of Gracilaria verrucosa. Data was analized by ANOVA and Least Significant Difference if the ANOVA result showed significant effect. The planting of Gracilaria verrucosa seaweed using different seed weights and planting intervals was significantly influenced the production of Gracilaria verrucosa. The highest seaweed growth  was was found at 50 g seed weight with 30 cm planting interval and 100 g seed with planting interval 10 cm (590,27 g m-1). The water quality in the research site still good for planting Gracilaria verrucosa seaweed. Key words: Gracilaria verrucosa, production, seaweed.

Abstract

The research was aimed to examine the effect of papaya leaf powder in diets on feed consumption, weight gain and feed conversion ratio of broiler chicken. The research was conducted in Experimental Farm of Animal Science Department, Agriculture Faculty, Tadulako University.   A Completely Randomized Design (CRD) was applied in this research. The treatment consist of five treatments with six replicates: (i) basal diets; diets with 3% of papaya leaf powder; (ii) diets with 6% of papaya leaf powder; (iii) diets with 9% of papaya leaf powder; and (iv) diets with 12% of papaya leaf powder. Data was analyzed by variance analysis based on experimental design. Results showed significant effect (P < 0.05) on feed consumption, weight gain and feed conversion of broiler chicken. The best results from this experiment were found in the diets with 9% of papaya leaf powder. Key words: Broiler, feed consumption, papaya leaf powder, weight gain.

Abstract

The  experiment on cocoa-pod husk processing by soaking it in KOH solution and fermenting    it with Saccharomyces sereviceae was conducted to study its effects on ruminal concentration of total VFA and ammonia in Kacang goat. The study was carried out with a 2x4 factorials randomized design. The first factor was soaking treatment (soaked in KOH solution or not soaked), while the second factor was 4 levels of Saccharomyces sereviceae concentrations (0, 5, 10, and 15%). Each treatment was repeated three times. Responses of soaking treatment on parameters observed were analyzed with a t test while those of Saccharomyces sereviceae levels were tested with a polynomial orthogonal test. Results indicated that there were no interactions between the soaking treatment and concentrationa of Saccharomyces sereviceae in affecting parameters observed. Concentrations of rumen VFA increased with increasing levels of Saccharomyces sereviceae. Soaking in KOH solution increased rumen fluid VFA concentration, but decreased that of rumen ammonia in Kacang goat

Abstract

The study aimed to determine the financial feasibility of laying hens business of CV. Belona Mandiri in Kecamatan Sigi Biromaru Kabupaten Sigi. The research was carried out on 27 July to 24 August 2009 in Kecamatan Sigi Biromaru Kabupaten Sigi. The research used a Case Study method. The commercial layer financial data was collected through the bookkeeping of     CV. Belona Mandiri since the commencement of the business. Data processed using the investment criteria such as NVP, the Net B/C and IRR. The research results showed that the Net B/C was 1.32% with the NPV of IDR 1,566,751,355 at interest rates of 16% and IDR 1,495,487,599 at interest rate of 18% while the IRR was 75.96%. This indicated that the layer business of CV. Belona Mandiri is financially feasible. Key Words: Financial analysis, layer poultry.

Abstract

The objective of this research was to identify the dynamic population of beef cattle at North Pamona of Poso regency. This research was an analytical descriptive study conducted using survey method on 572 respondents taken using a purposive sampling method from all villages at         North Pamona. The result showed that the composition of beef cattle were 533 (34.88%) bull and 995 (65.12%) cows. The total number of bull calves, bullock and bull were 93, 100 and 340, respectively, while the heifer calves, heifers and cows were 135, 130 and 738 respectively.          The birth rate was 30.89% or 14.83% of the total population whereas the motility rate was 2.7% so that the natural increase was 12.13%.  Key words: Beef cattle, population and reproductivity.

Abstract

The objective of this research was to study how components of the Coastal Community Economic Development Program implemented in Pangkep Regency could improve the welfare of fishermen. This research used a linear multiple regression method. Research results showed that  the community economic welfare in Pangkep Regency was simultaneously influenced by revolving fund, productive economic fund, cooperatives, public consultation (socialization), technical and managerial training. Partially, revolving fund was the most significant variable. Training variable was the least significant due to various factor namely the heterogeneity of education level among the community as well the lack of understanding in absorbing the Coastal Economic Development Program message. Key Words: Behavior, coastal community, income.

Abstract

The research was conducted to study the growth model of Siganus canaliculatus which was based on body length parameters. The research was done through survey which was initiated by measuring the body length of n fish samples drawn from N fish population. The size of fish population (N) was based on the fish basket times the number of fish in each basket for every landing catch. The number of fish sample required was based on variability of catch yield for each catching period. Data collected was analysed on the basis of functional relationship between fish fork length (FL) and body weight (W) following the non linear mathematical equation W (i) = qFL(i)b. A model simulation was then performed using the techniques of data interpolation and extrapolation. The regression coefficient value for the relationship of the two parameters was 2.4. indicated that the growth model of the Siganus canaliculatus was allometric. Key words: Allometric, extrapolation, interpolation, model, siganus canaliculatus, simulation.

Abstract

The utilization of the fishery potency of Tojo Una-Una Regency has not been optimum resulting in the low income of fisherman. The research was aimed to optimize capture fisheries management (economic and ecology sustainability) Data used in this study included Maximum Sustainable Yield (MSY) and primary data analyzed by using Linear Goal Programming Method. Results showed that the optimal number of catch fishery effort unit operated in the marine area of Tojo Una-Una Regency consisted of 197 gillnet units, 132 liftnet units, 235 handline units, 33 roll line units and 16 purse seine units. The management of this fishery effort would meet the targets of fisherman maximum income which was IDR 17.56 billion, domestic income which was IDR 780 million, fish consumption which was 6.775,92 ton and also could employ 32,87% labour. The use of catch fishery resources reached a level of 99-100% (indicated overfishing).
