Abstract

Neverita didyma was a sea snail that included in the catch side from fishermen of Anadara granosa. The snail usually consumed with boiled and steamed. N. didyma can be used as a mineral source that needed by human. Information about characteristic of snail and its handling process on boat and collector was important. The aim of the research was to determine characteristic (rendemen and morphometric), handling process and mineral content of N. didyma. This research consisted of several stages. The stage was determination of characteristic of N. didyma, handling process and analisys of mineral content using Atomic Absorption Spectrophotometry (AAS). N. didyma had rendemen characteristic. each of characteristic was shell; 60.73%, meat 25% and offal 14.27%. Morphometric of snail was length 34.8 mm, width 28.33 mm and weight 12.86 g. Handling of N. didyma on boat and collector had not done well. mineral content of meat consisted of magnesium, potassium, sodium, calsium, phosporus, iron, zinc, and cooper.

Abstract

The purpose of this research was to investigate the sensory, microbiological and chemical characteristics of naniura tilapia (Oreochromis niloticus) with different types of acid and marinade time. The research was conducted on May until October 2015. This research used a Factorial Randomized Block Design (FRBD) two factors, the type of acid factor (Jungga citrus, lime, and citric acid) and marinade time factor (3 hours and 5 hours). Each treatments was replicated three times. The attributes observed were sensory test, pH, water content, and microbiological/TPC. Proximate and amino acid analysis will be done for all 3 hours marinade treatment. The results of organoleptic test showed that treatment of acid type and marinade time did not significantly affect the appearance and meat consisten but significantly affect on taste and aroma. The results of analysis TPC Jungga citrus treatment with lime showed the same value. While the value of TPC citric acid was higher but still safe for consumption. The results of proximate analysis for the three types of acid showed that Jungga citrus is the best nutrient content that the water content 63.25%, ash content 3.46%; 7.40% fat content, protein content 25.90% and carbohydrate 0.98 %. Analysis of the amino acid profile in naniura produced 17 amino acids, 9 essential amino acids and 8 non-essential amino acids

Abstract

The purpose of this research was to utilize water lettuce (Pistia stratiotes) as raw material of kombucha drink and was to investigate the effects of fermentation time on chemichal characterictics and antioxidant activity of water lettuce (Pistia stratiotes) leaves kombucha. This research used randomized block design (RBD) consisted of 1 factor treatment which was fermentation time (1,4,8 and 12 days) with 3 replications. The variables observed were total sugar content, pH, total acidity, alcohol, antioxidant activity use DPPH method and sensoric analysis on appereance, colour, flavor, and taste of the find product. The result showed that fermentation time gave significant effect on chemichal analysis (total sugar content, pH, total acidity, alcohol), antioxidant activity and sensoric analysis (appereance, colour and taste), but no effect on flavor was observed.

Abstract

This research studied about the effect of temperature and immersion time in cold water to the quality of catfish (Pangasius pangasius) meatball. This study used a factorial randomized block design models with two factors that were the temperature of water immersion (4 °C, 16 °C, 26 °C) and the immersion time (5, 15) minute. Each treatmens were repeated twice. Parameters observed were chemical analysis that includes moisture content, fat content, protein content and physical analysis that includes the gel strength, expressible moisture, microstructure and sensory analysis in the form of hedonic quality test. The results showed that the treatment temperature and immersion time significantly (p<0.05) affected the water content, gel strength, expressible moisture and sensory, while the levels of protein and fat were not significant. Based on microstructural observations using a SEM (Scanning Electron Microscope) show the structural differences between the samples treated and treated not. The best treatment is the treatment temperature of 4 °C and immersion time of 5 minutes.

Abstract

The purpose of this research was to utilize water hyacinth biomass and sneakhead waste as substrats for biogas production as a renewable energy source by different treatment on substrate composition. This research used experimental method in anaerobic batch reactors with Liquid Displacement and Atomic Absorbtion methods using NaCl and NaOH solutions. The results in this research were analyzed by descriptive method. The observed parameters were rate and accumulation of biogas and methane production, and slurry’s parameters such as themperature, pH, BOD, COD, TS, VS, and C/N ratio. Results showed that the difference of substrates composition in reactor A produced the highest biogas and methane accumulation. Whereas in reactor B produced the highest methane percentage.

Abstract

The purpose of this research was to investigate the effect of addition rosella powder to characteristics sausage of catfish (Clarias gariepinus) and knowing the best formulation the acceptance of panelists on the antioxsidant activity. This research was used random block design (RBD). The treatment of addition rosella powders were 1%, 2%, 3%, 4%, and 5%. Parameters of this research were physic analysis such as elasticity, colour and pH. Chemical analysis such as water and ash. Sensoric analysis such as display, texture, colour, flavor and taste.

Abstract

Mud crab is one of brackish water commodity with high ecological and economical value, which is a lot of demand from the local, regional and also foreign market. This study aims to determine autotomi induction effect on the survival rate, molting, and growth of the mud crab (Scylla serrata, Scylla tranquebarica, and Scylla paramamosain). This research was conducted in November-January 2013, which is located in the traditional ponds in Anggoeya Village, Poasia District, Municipality of Kendari, Southeast Sulawesi. It used a completely randomized design (CRD) with 3 treatments and 3 replications, thus in this study, theirs 9 units of experiments which each experimental unit consisted of 10 crabs test. Treatment was applied in this study is the autotomi induction treatment on the mud crab S. paramamosain, S. tranquebarica, and S. serrata. Data were analyzed by analysis of variance (ANOVA). If the results showed the significant effect, it would proceed by the least significant difference (LSD) at the 95% confidence level (α = 0,05). As a tool to carried out the statistical tests were used the SPSS version 17.0 program package. The results showed that autotomi induction treatment on the different types significantly the different results (p<0,05) to the survival rate and molting perfection, but it was not significantly different (p>0,05) to the absolute growth and molting period of the mud crab (S. paramamosain, S. tranquebarica, and S. serrata).
