Abstract

MIGAS Block of Toili, Tolo Bay, Central Sulawesi Province has been developed by Joint Operating Body Pertamina Medco E&P Tomori South since 2004. There are 8 main coral sandbas located this block. Those are Taka Tiaka, Tambaga, Mbunginang, Takasuda, Ranggasang, Lana’ang, Buntar and Pakangkah Alonya. Corals reefs as primary component in marine ecosystem have important roles for the sustainability of fisheries resources that utilized by local fishermen. Also, corals have been used as indicators for assessing the health of the ecosystem, primarily for assessing the impact of the activity reated to fishery and oil and gas exploitation in Toili Block. This research used line interception transect to measure the growth  and long life form of coral. The Analysis was based on percentage of coral cover (English et al., 1997). The Corals Mortalitas Indeks is use to asses canges life hard corals to be dead corals. Mortality index was used to asses the change from live to dead coral. The determination of coral reefs condition was referred to Ministrial Decree No: KEP-04/MENLH/02/2001. Coral cover percentage found in Tiaka was 28,82%-68,70% (IM 0,59 and 0,13); Taka Tambaga 9,70%-55,66% (IM 0.89-0,38); Taka Suda’ 13,44%-42,62% (IM 0.72-0,52); Taka Mbunginang 21,68%-48,36% (IM 0.76-0,43); Taka Ranggassang 20,64%-42,00% (IM 0.70-0,50); Taka Lana’ang  26,92%-53,5% (IM 0.73-0,37); Taka Buntar 24,08%-38,94% (IM 0.70-0,51) and Taka Pakangkah Alonerya 77,24%-72,16% (IM 0.08-0,17). Coral reefs that found along the coastal water of Central Sulawesi particularly by the terrestrial area mostly in bad to moderate condition while those that opposed to the open sea ((Tolo Bay) are found to have moderate to very good condition.Keywords: coral reefs, condition, block toili.

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 current study was conducted to identify ectoparasites, infected organs, prevalence and intensity of ectoparasites in cultured common carp (Cyprinus carpio L.). Experimental animals were collected from ponds in 9 villages in 3 subdistricts in Sigi District. It was found that generally the common carp was infected by Dactylogyrus sp., Trichodina sp., Argulus sp., Epistylis sp., Chilodonella sp. and Ichthyophthirius multifilis. Infected organs consist of skin, fins and gills. The prevalence of ectoparasites per subdistrict was between 0.0 and 66.7 % and the intensity ranged from 0.0 to 3.0 individuals/fish. Key words: common carp, ectoparasites, prevalence, intensity.

Abstract

The aimed of this research was to evaluate the effect of using fermented extracted herbals on income over feed cost (IOFC) and feed economic effiency on broiler rearing. Material used were80 unsexing DOC strain MB-202 produced by PT. Japfa Comfeed Indonesia Tbk. Herbals used includegarlic (Allium sativum L.), ginger (Zingiber officinale Rosc. var. rubrum), turmeric (Zingiber officinale Rosc.), wild ginger (Curcuma xanthorrhiza ROXB), and betel leaf (Piper Betle L.). Herbals were extracted, mixed,and fermented with EM4. then added to drinking water. The experiment usedaComplete Randomized Design with 4 treatments and 4 replications. The treatments were 0%, 10%, 15%, and 20% fermented extracted herbals in drinking water. The basal feedwas commercial complete feed produced by PT. Charoen Pokphand Indonesia. Results showed that there were no significant effect (P>0.05) on using fermented extractedherbals to income over feed cost (IOFC) and feed economic efficiency on broiler rearing. Income over feed cost  (Rp/chicken) were 5,099,75 ; 4,758,92 ; 4,530,34 ; and 4,053,26 respectively. Feed economic efficiency (Rp/chicken) were 12,061,09 ; 12,244,09 ; 12,094,16, and 12,500,86 respectively. It could be concluded that using fermented extracted herbals did not influence income over feed cost (IOFC) and feed economic efficiency on broiler rearing. Keywords: Fermented extracted herbals, income over feed cost, feed economic efficiency, broiler.

Abstract

Chlorella sp. as a source of nutrition for aquatic organisms. Chlorella sp. is one way to meet the needs of aquatic organism feed. In the culture of Chlorella sp., light plays an important role in the process of photosynthesis. The photoperiod of the light will affect the density of cells and chlorophyll produced by Chlorella sp. Therefore, it is necessary to analyze cell density and chlorophyll content with different lighting periods. The purpose of this study was to determine cell density and chlorophyll-a content with different light photoperiode in Chlorella sp. culture laboratory scale. This study was used a complete randomized design with 3 treatments (A (12T: 12G), B (16T: 8G), and C (20T: 4G) and 6 replications. The results show that treatment B (16T: 8G) produces the highest cell density ( 1733.5 x 104 cells / ml) while the highest chlorophyll-a content in treatment A (12T: 12G) was 9.76 μg / ml.

Abstract

Soaking beef jerky can improve chemical quality, flavor and consumer acceptance of the products produced. Liquid smoke functions as a preservative, a specific flavor and aroma. The research aims to analyze the chemical quality and antioxidant activity of beef jerky that has been soaked with the addition of liquid coconut shell smoke. The study used a Completely Randomized Design (CRD) with 5 treatments (D0 = jerky without soaking and adding liquid smoke, D1 = jerky with 2 hours soaking and adding 1% liquid smoke, D2 = jerky with 4 hours soaking and adding 1% liquid smoke, D3 = beef jerky with 6 hour soaking and 1% liquid smoke addition, D4 = jerky with 8 hour soaking and 1% liquid smoke addition) and 3 replications. Levels of protein, fat, water and antioxidant activity of beef jerky were observed in this study. Data were analyzed variance (ANOVA) with Duncan's further test. Immersion treatment and addition of coconut shell liquid smoke on beef jerky showed a chemical quality that was not statistically different in all treatments, but an increase in protein content (34.28% - 39.28%), fat content (3.98% - 5 , 25%), water content (11.02% - 12.33%) and antioxidant activity (355.23% - 201.98%).
