Analysis and identification of Pseudomonas sp. and molds on dried anchovy (Stelophorus sp) products produced by the people of Toniku Village, Halmahera Barat Regency, North Maluku Province
No full textThis research was conducted to determine the characteristics of Pseudomonas sp. and mold on dried anchovies. The sample in this study was obtained from the fishing community of Toniku Village, West Halmahera Regency, North Maluku Province. The stages carried out in this study were 3 (three) stages, namely the sample preparation stage, the analysis phase and the identification stage of Pseudomonas sp. and mold. The results showed that the characteristics of the Total Plate Count (TPC) of dried anchovy in the Toniku Village obtained a different composition from each other, with the highest log Total Plate Count (TPC) obtained, namely 5.5 or 3.2 x 105 Cfu/g or 320.000 cells bacteria, while the lowest Total Plate Count (TPC) log was obtained, 2.5 or 3.1 x 102 Cfu/g or 310 bacterial cells and for total Pseudomonas bacteria from the three sampling locations no growth was found. The highest total log fungi were obtained ie 5.6 or 3.7 x 105 Cfu/g or 370.000 mold cells, while the lowest total log fungi were obtained which were 2.4 or 2.6 x 102 Cfu/g or 260 mold cell
The growth of seaweed (Eucheuma cottoni) at different fertilizing doses in the waters of the village of Ghonebalano, Duruka District, Muna Regency, Indonesia
No full textThe study was conducted aiming to test different fertilizer doses on the optimal growth rate of Eucheuma cottonii seaweed. The study was conducted from July to August 2016 in the waters of Ghonebalano Village, Duruka District, Muna Regency, Southeast Sulawesi. The study used NPK fertilizer with the composition of the element nitrogen (N) 15%, phosphate (P2O5) 15%, and potassium (K2O) 15%. The study used a Randomized Block Design (RBD) with 3 (three) levels of fertilizer doses and 3 (three) groups so that the number of experimental units was 9 (nine) units. While the treatments tested in the study were treatment A (without fertilizer/control), treatment B (fertilizer dose 1 g/L), and treatment C (fertilizer dose 2 g/L). The results showed that the difference in fertilizer dose significantly affected the growth rate of Eucheuma cottonii seaweed. A dosage of 2 g/L of fertilizer gives the best rate of growth of Eucheuma cottonii seaweed while the water quality at the study site shows that it is still in the optimal range for the growth of Eucheuma cottonii seaweed
Mangrove damage level in the waters of Berakit Village, Bintan Island, Indonesia
No full textMangrove forest or better known as mangrove forest is an ecosystem found in coastal waters and has an important ecological and economic role. This study aims to measure and determine the health status of mangrove forests that grow in the waters of Berakit, Bintan based on the level of tree density. The study was conducted in August to November 2019 which was conducted at twenty station points spread from the mainland to the coastal waters of Berakit. Field data collection was performed using the quadratic transect line method, 10x10 m2 plot was made along the transect line to measure the diameter of the tree at breast height (DBH) which has a trunk circumference for each mangrove tree at breast height of about 1.3 m. Mangrove health status based on the level of density of mangrove trees is included in the criteria of Good with Very Solid category. Rhizophora apiculata is a species of mangrove that grows well and has an important role in the waters of Berakit, Bintan island
Growth and survival rate vannamei shrimp (Litopenaeus vannamei) in various doses of fertilizer and density
No full textVannamei shrimp (Litopenaeus vannamei) is a commodity that is expected to not only increase options for farmers but also sustain the rise of shrimp farming business in Indonesia. One important factor in shrimp farming is the availability of feed. In addition to the availability of natural feed during cultivation, stocking density is also very influential in the survival rate and growth of shrimp vannamei. The research was conducted in September-December 2016 farms Bonea Village District of Lasalepa Muna with Test the different dosages with different stocking density. The study used a Random Group Factorial, which is based fertilization (Factor A) with three levels and stocking density (Factor B) as many as three levels, each with three replications so that all 27 units experimental unit. The results showed that the combination of factors dose of 0.7 g of urea + 0.9 g TSP and stocking density factor of 10 individuals per container provides prawn post larvae growth vannamei most excellent and a combination of factors Urea fertilizer dosage of 0.9 g TSP + 1.1 g and stocking density factor of 20 individuals per container provides a survival rate of post larvae vannamei most good. Water quality media for research in the range that is optimal for the growth and survival of post larvae vannamei
Economic studies and management policies of Lirang Island, Southwest Moluccas, Indonesia
No full textIn Lirang Islands border the fisherman was interact with Republic of Timor Leste Democratic because of difficult accessibility. Therefore, management and development of small islands were needed which fit with its potential, characteristic, and problems. The aim of this research were to analyze economic condition of Lirangs people using fishing rate analysis; to analyze policy of border and formalize the strategic of development Lirangs Island using public policy analysiss and SWOT Analysis. Commonly, Lirangs fisherman has fishing rate above 1 and it showed that they have well-being level to fulfill their need. A vew policies that support the development of Lirangs island as small island were: to improve their autonomy from fishing facilities and infrastructure (market, dock/jetty, base of landing base, ice factory, cold storage and water) and training for fisherman through founding, to improve their skills and control the technology; to improve the social and economic collaboration with Repubic of Timor Leste Democratic
Probiotic aplication for growth and survival rate of vaname shrimp Litopenaeus vannamei with different density
No full textThe study aimed to determine the growth and survival of Litopenaeus vannamei shrimp with the application of probiotics to different stocking densities. The study was conducted from May to June 2018 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, Duruka District, Muna Regency, using a Completely Randomized Design (CRD) with three levels of solid stocking treatment namely treatment A is 18 individu per container, treatment B is 24 individu per container and treatment C is 30 individu per container with three replications. Data analysis using Variance Analysis (ANOVA) at the confidence level of 95% (α 0.05). The results showed that the highest daily growth was obtained at 24 individual densities of 5.88% per day, compared to 18 individual densities of 5.86% per day and 30 individual densities of 5.74% per day. The highest absolute growth is obtained at 24 individual density of 2.43 g per individu, then 18 individual density of 2.15 g per individual, and the lowest at 30 individual density of 2.02 g per individual. Survival at a density of 18 individual and a density of 24 individual at 88.89%, while a 30-ind density of 86.67%. Analysis of variance (α 0.05) showed that the application of probiotics to different stocking densities had no significant effect on the daily growth rate of vannamei shrimp (p<0.939), absolute growth of vannamei shrimp (p<0.080), and survival of vannamei shrimp (p<0.744)

Length-weight relationship and stock assessment of tuna fish (Euthynnus affinis) in East Halmahera waters
No full textThe study was conducted in December 2016 to February 2017 in East Halmahera waters with the aim to examine the relationship between the length of weight and potential and the level of utilization of tuna. The results showed that the long frequency distribution of tuna was ranging from 10.0-28.2 cm, with a maximum length value of 29.93 cm, a growth coefficient of 0.74 per month and a measure of fish worth catching for spawning. The relationship between the weight of tuna in East Halmahera waters is W=0.0078L3.2982, where the length of tuna is greater than this weight increase due to environmental conditions and oceanographic parameters that affect the growth of tuna. The results of the MSY analysis or the sustainable resource potential of tuna in East Halmahera waters using the Fox method, found that the MSY value or sustainable potential of tuna was 4,176.54, with a maximum effort level of 8,047 Trips. This utilization rate is still low from the value of MSY and continues to decline this is due to the low value of fishing efforts
