Abstract

The use of probiotics as an effort to improve the cultivation environment and suppress pathogenic disease proved can help some of the problems in the cultivation of shrimp ponds. This study aimed to determine the effect of the concentration of probiotics effervescent tablets on the growth of Vibrio sp. The method used in the study was an experimental method with 2 treatments, water pond with pond water treatment level is not sterile (non aseptic), pond water that has been sterilized (aseptic) and water pond with bacteria Vibrio sp. and the concentration of probiotics effervescent tablet with a level of treatment 20%, 30% and 40% maltodextrin with 2 repetitions. The ability of probiotics effervescent tablet on the growth of Vibrio sp. it is known to test the TPC (Total Plate Count). Based on the TPC tests have shown that probiotics contained in effervescent tablets with a concentration of 20% maltodextrin has the ability to be most effective in inhibiting or suppressing the growth of Vibrio sp. These indications prove extremely decreasing the amount of bacteria Vibrio sp. on pond water after 48 hours underway. Statistical test result, see from the effect of the concentration of probiotic effervescent tablets on the growth of Vibrio sp. on a shrimp pond water, showed no significant differences (P> 0.05).Keywords: probiotic, effervescent tablets, Vibrio sp., Total Plate Count

Abstract

The liquid waste of palm oil containing high nutrients and can be used as a source of nutrients for growth microalgae such as Chlorella sp. A research aims to understand the effects of palm oil liquid waste addition in the media toward the growth of Chlorella sp. has been conducted from May – July 2016. The culture was conducted for 20 days. There were 4 treatment applied, namely P0 (0% waste), P1 (20% waste), P2 (25% waste) and P3 (30% waste). Parameters measured were the abundance and biomass of Chlorella sp., temperature, pH, nitrate, and phosphate. Result shown that the best growth of Chlorella sp. was in the P1, the abundance was 61.45 × 105 cells/ml and the biomass was 0.36 g/l. During the research, the nutrient available in the media decreased, from 1.13 to 0.09 mg/l (nitrate) and from 3.54 to 0.48 mg/l (phosphate). This fact indicates that the nutrient have been used for growing the microalgae. Based on data obtained, it can be concluded that the palm oil liquid waste can be used as a source of nutrients for Chlorella sp.Key words : Palm oilliquid waste, nutrients, microalgae, Chlorella sp.

Abstract

This research was aimed to evaluate the effect of banana budsuplementation to the quality of shredded catfish (Clarias gariepinus). The methodused was experimental, composed as non factorialcompletely randomized design (CRD).The treatment was the addition of banana bud into the shredded catfish, whichwas varied at 4 levels, namely: 0 % or original shredded catfish as the control(A0), addition of banana bud 25% (A1), 50% (A2) and 75% (A3) for 10 tones fishmeat each. The parameters used were organoleptic evaluation and proximatecomposition. The result showed that the addition of banana bud 75% (A3) into thefish meat was producing the best shredded catfish, characterized by the goodappearance with the brown-grey colour; have special good taste of shredded fish;fluffy fiber, soft and dry textured; and more tasty flavor. The product contained6,89% moisture, 26,25% protein, 27,19% fat, 6,31% ash, and 2,57% fiber.Keyword: banana bud, catfish, shredded fish,

Abstract

The study was conducted on 10 February to 26 February 2016. This study is intended to document the implementation and monitoring of fishing ports and sanitation problems. This study used a method of investigation. Data in tabular form the results of the research is conducted in the form of tables and descriptive by comparing the behavior or conditions that have been analyzed with national (NO 52A/KEPMEN-KP/2013) and international (Codex Alimentarius, 2009) standards. Based on the application of research results in sanitation Sibolga Fishing Port is good looks of infrastructure condition assessment by panelists, namely 66.7%, but the fish auction is still not good hygienic conditions, namely 44.4%. In the application of sanitary facilities at the fish auction in comparison with national and international provisions will be obtained from a percentage of the value of 25% to 41.6% for national and international. Difficulties in managing the auction sanitation and ecological areas in Sibolga Fishing Port is low awareness of users and visitors in the maintenance and monitoring of hygiene, so that some indicators were observed not met.Keyword : Sanitation, Sibolga Fishing Port, Fish Auction

Abstract

This research was aimed to determine the effect of fortifying snakefish (Channa striata) protein concentrate in baked brownies on nutritional value and consumer acceptance with different concentrations. The research was conducted in two stages: 1) ​​the production of snakefish protein concentrate, 2) the production of baked brownies with addition of snakefish protein concentrate. The method used in this research was an experimental method, using a completely randomized design (CRD) non factorial. Based on consumer acceptance the results showed that the baked brownies fortified 25% of snakefish protein concentrate (B3 treatment) was the best treatment. Based on proximate analysis that the lowest water content (14.14%) also in the baked brownies fortified 25% of snakefish protein concentrate, while the highest water content (23.54%) was without addition of snakefish protein concentrate (B0 treatment); the highest protein content (22.46%) was in B3 treatment and the lowet protein content (7.22%) in B0 treatment; the highest fat content (17.11%) was in baked brownies fortified 20% of snakefish protein concentrate (B2 treatment), while the lowest (15.67%) was in B0 treatment.    Keywords: Consumer acceptance, baked brownies, protein concentrate, Channa striata.

Abstract

Senapelan River receives many types of pollutants originated from households and industries present around the river. The presence of the pollutant may decrease the water quality and affects the meiofauna community living in that river. A research aims to understand the water quality of the river based on meiofauna structure was conducted on June-July 2015. There were 3 stations and the meiofauna was sampled 3 times, once/ week. The types of meiofauna was then identified and the abundance, uniformity and dominancy index were calculated. Water quality parameters such as temperature, turbidity, depth, pH, dissolved oxygen, substrate type, and organic materials were measured. Result shown that there were 5 spesies (4 classes) of meiofauna. There were Oligochaeta (1 spesies), Polychaeta (1 spesies), Nematod (2 spesies) and Turbellaria (1 spesies). The abundance of the meiofauna was ranged from 39-1,337 organism/m2, the diversity index value (H’) was 1.39 – 2.04, the dominance index value (C’) was 0.27 – 0.42 and the equitability index value (E) was 0.70 – 9.91. These values indicate that the Senapelan River is slightly polluted, but it is able to support the live of specific meiofauna only.Keyword : Meiofauna, Bioindicator, Senapelan River
