Abstract

Siamese fighting fish (Betta splendens) is a freshwater ornamental fish that has a potential both in the domestic market and international market (export). Some studies on biological aspects of the Siamese fighting fish have been conducted.  However, information on the embryonic development of the fighting fish is lack.  The study aims to determine the stage of embryonic development in fighting fish. The experiment was conducted at the Laboratory of Aquaculture, Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu. The results showed that the development of fish embryo can be divided into several stages, including cleavage, morula, blastula, gastrula, and organogenesis. The egg of the fighting fish was hatch in 35 hours after fertilization. Key words: Betta splendens, fish egg, embryogenesis, and larvae

Abstract

This study aims to determine the effect of stocking density on growth of Trout Grouper (Plectropomus leopardus) were cultured in the floating net cage. The study was conducted in Tolobundu Bay, Popidolon Village, Liang District, the residence of Banggai Islands, Central Sulawesi Province, during period of June to August 2011. Experimental organisms used were Trout Grouper (Plectropomus leopardus) with initial body weight of 200 g/head. Twelve 1 m x 1 m x 1m floating net cages with mesh sizes 1 inch were used for this experiment. Feeds given were trashed raw fishes amounted to 4-5% of the grouper biomass, fed three times daily. Experimental design used was completely randomized design (CRD) with 3 treatments, namely stocking densities of 15; 20 and 30 heads/m3, respectively, and with four replications. The results showed that the stocking density have a highly significant effect on the growth of Trout Grouper (Plectropomus leopardus), where the highest growth was performed by those cultured with stocking density of 15 heads/m3.Key words : stocking density, growth, Trout Grouper.

Abstract

The objective of this research was to determine the genetic variation of the Maleo (Macrocephalon maleo) based on blood protein polymorphism. Material of the research was blood of Maleo coming from different original habitat, coastal and inland area. PAGE-TYLE (Polyacrilamide Gel Electrophoresis-Thin Layer Electrophoresis) was used in this research. Parameters observed were genotype at four locus Pre Albumin (PAlb), Albumin (Alb), Ceruloplasmin (Cp) and Transferrin (Tf). The obtained various data were used to analyze gene frequency, individual heterozygosity as well as average heterozygosity. The result showed that gene frequencies at allele A and B of four locus Maleo both  in coastal and inland habitat were the same at PAlb locus and Tf locus, that was 0.5; Alb locus was 0.33 vs 0.67 and 0.67 vs 0.33, respectively; Cp locus was 0.5 vs 0.67 and 0.5 vs 0.33, respectively. Individual heterozygosity of four locus Maleo in coastal and inland habitat were the same at PAlb and Tf  that was 0.5; Alb was 0.4555 respectively; Cp was 0.5 vs 0.4555 respectively. Average heterozygosity in coastal and inland Maleo were 0.3911 and 0.3822, respectively. In conclusion, Maleo in coastal and inland habitat showed the same value of diversity relativity due to uncontrolled assortative mating.Key words: Maleo (Macrocephalon maleo), genetic variation, polymorphism blood protein

Abstract

Government program that sets seaweed and results olahanya as commodity resulted in an increase in the amount of waste from processing into carrageenan seaweed cause environmental pollution. By him that, has done research on the nutritional evaluation of the waste and the efforts to improve the nutritional value of the waste that can be used as feed. This study uses bioconversion technology and using Rhizopus oligosporus as an inoculant. The study was conducted in two phases, namely the early stages of an evaluation study of the nutritional value of waste carrageenan and test its ability to grow on medium Rhizopus oligosporus waste. Furthermore, the implementation of the waste carrageenan bioconversion using Rhizopus oligosporus on some level in the medium (w/w). Preliminary results demonstrate that the solid waste seaweed had higher levels of crude protein 2.43%, fat 0.52%, ash content 4.07%, carbohydrates 7.25%, crude fiber 2.48%, 85.73% water, cellulose 23.29% and hemicellulose 16.51%. Furthermore Showed that Rhizopus oligosporus can grow well on media without the addition of carrageenan waste Nutrients. Bioconversion can improve the nutrient content of solid waste seaweed. Bioconversion of waste produced has a moisture content between 73.91 to 75.97%, protein content between 13.27 to 16.78%, fat content between 0.20 to 0,25%, ash content between 18.15 to 20.60%, a pH value between 6.56 to 7.35 while the crude fiber content Obtained between 13.45 to 20.37%. Based on the series of this study, it can be concluded that the solid waste Eucheuma cottonii seaweed can be used as a growing medium of Rhizopus oligosporus and can improve the nutritional content of seaweed waste. Use of inoculum in the medium waste carrageenan is possible until the level of 15% (w/w).   Key words: Bioconversion, byproducts, seaweed processing, solid waste.

Abstract

Preservation and processing of meat into beef jerky can extend storage life, but it is still determined by the packaging method. The purpose of this study was to determine the effect of packaging method on the level of change in the chemical quality of ground beef jerky. This research was conducted at the Laboratory of Animal Product Technology, Faculty of Animal Husbandry and Fishery, as well as the Agroindustry Laboratory of the Faculty of Agriculture, Tadulako University from 4 October 2018 to 12 January 2019. The research designed by applying a Completely Randomized Design (CRD) with 5 treatments and 3 replications, with treatments D0 = jerky without packaging, D1= jerky completely packed up, D2= jerky + Aluminum foil zipper with air cavity ± 0.0019 within 1 cm, D3= D0 + Aluminum foil zipper with air cavity ± 0.0038 within 1 cm, D4= D0 + Aluminum foil zipper with air cavity ± 0.0057 within 1 cm. The observed parameters were content of protein, fat and water. The results showed that ground beef jerky with different packaging treatments, had no significant effect (P> 0.01) on protein content (D0= 37.20; D1= 38.17; D2= 38.37; D3= 38.21; D4= 28.37%) and the fat content of ground beef jerky (D0= 6.52 ±; D1= 6.65; D2= 6.67; D3= 6.67; D4= 6.77%), but have significant effect (P <0.05) of jerky water content (D0= 22.08; D1= 25.28; D2= 24.60; D3= 23.50; D4= 22.12). The Duncan's test of the water content significantly affected, after storage for 3 months. Water content is an important component in jerky, because it also determines freshness and durability. It also affects the appearance, texture and taste of food. Therefore, the method of packaging using aluminum foil zipper with an air cavity of ± 0.0038 1 cm produces the best chemical quality of ground beef jerky.Keywords: Ground beef jerky, packaging method, storage life

Abstract

The aims of this study were to examine the potential of mangroves and the factors causing mangrove damage, analyze the economic valuation of mangroves and formulate a mangrove ecosystem management strategy in South Larompong Subdistrict. Data collection was carried out by using purposive sampling with a number of respondents of 65 people. Data was then processed and analyzed descriptively, spatially, and Analytic Hierarchy Process (AHP). The results showed that there was a reduction in the mangrove area about 69.89 Ha from 2014-2018 due to the conversion of mangroves into ponds and settlements. The total economic value of mangroves in 2018 was Rp. 86.603.426.151, consisting of direct use value of Rp. 61.428.000.000, indirect use value (Indirect use value) of Rp. 7.638.926.151, option value of Rp. 15.114.000.000, and the existence value of Rp. 2.422.500.000. The instructions of mangrove management in South Larompong Subdistrict are planning the use of mangrove ecosystems, conservation and rehabilitation, providing extension on preservation of mangroves, optimizing the utilization of mangrove resources, strengthening community institutions, and law enforcement.Keywords: Mangrove Ecosystem, Level of Damage, Economic Valuation.
