Abstract

 AbstractThe research was conducted from August to September 2020 at the Waste Treatment Laboratory, Faculty of Fisheries and Marine, Riau University. The purpose of this study was to determine the effect of giving organic fertilizer as a result fermented of rice washing water on the culture of Clorella sp. and determine the best dosage of organic fertilizer from fermented rice washing water in the culture of Clorella sp. The research design was an experimental model using a completely randomized design with one factorial pattern (CRD) with 1 factor, 4 treatment and 3 replications. The treatment  used was AB0: 1 ml / L walne fertilizer (control), AB2: 2 ml / L rice washing water fertilizer, AB4: 4 ml / L rice washing water fertilizer, AB6: 6 ml / L rice washing water fertilizer. Cultivation wascarried out for 14 days. The results showed thatthe application of washing water fertilizer rice with different doses had an effect on population density and growth rate in cultures of Chlorella sp. The application of washing rice water fertilizer with a dose of 4 ml / L of water gave the best results with a maximum density of 600 x 104 cells / ml and a specific growth rate of 0.256 / day and the highest population peak on day 8. The results of water quality measurements during the study obtained temperatures of 28-31 0C, pH 7.3- 8.1, and DO 4-5 mg / L. Keywords: Clorella sp., Rice washing water, population density, growth rate

Abstract

AbstractThis research aims to determine the effect of adding lime (Citrus aurantifolia) juice on the quality of nila fish (Oreochromis niloticus) during storage at room temperature. The research method was used an experimental method, which is to lubricate fresh nila fish with various concentrations of lime juice and stored at room temperature. This research was carried out in stages by conducting preliminary research to determine the best lime concentration and continued to the main research. The research data were analyzed using a non factorial randomized block design (RBD). The parameters tested were organoleptic (appearance, texture, aroma, and taste), Total Plate Count (TPC), water activity (aw), and pH level. Research shows that the use of lime juice has a significant effect on the quality of nla fish stored at room temperature with a concentration of 50% lime juice as the best treatment with characteristics: elastic texture, slightly dense, compact, fresh sour, delicious, and specific fish taste that reshly added with lime acid, the TPC value was 38.10x102 colony / gram, the average pH value was 4.13, and the average aw value was 0.81 for storage for 0 hours to 12 hours.Keywords: lime, nila fish, quality, natural preservative.

Abstract

ABSTRACTThis study aims to determine the analog rice formulation based on sago and taro with fortification of fish oil as a functional food. The treatments given consisted of (M3S, M5S) analog rice based on sagowith 3 and 5% fish oil fortification, (M3TS, M5TS) analog rice based on taro-sago with 3 and 5% fish oil fortification, and (M3T, M5T) analog rice based on taro with 3 and 5% of fish oil fortification. Analysis parameters include organoleptic test (appearance, taste, aroma, and texture), as well as proximate analysis. The best treatment combination is analog rice from sago fortified with fish oil as much as 5% with intact characteristics and creamy-yellowish color, the aroma no longer shows rancid from fish oil, tasteless, and a slightly fluffier texture. Protein value of 1.46% (db), water 9.45% (wb), ash content 4.25% (db), fat content 4.96% (db), crude fiber 18.66% (db), and total carbohydrates 68.13%.   Keywords : Analog rice, sago, taro, fish oil

Abstract

ABSTRACT            Osphronemus gouramy and Channa micropeltesinhabit the the Koto Panjang Dam, Riau. The presence of anthropogenic activities may produce heavy metal that enter the water and thus accumulate in the organisms living in that area. A study aims to understand the heavy metal content in gill, muscle and kidney of O. gouramy and C. micropeltesliving in that dam, as well as in the water and in the sediment has been conducted in April 2019. Samplings were conducted 2 times, once/ 2 weeks. Results shown that  the heavy metal content in O. gouramywere as follows: Pb 0.0873 mg/kg and Cd 0.0426 mg/kg (gill), Pb 0.0684 mg/kg and Cd 0.0394 mg/kg (kidney), Pb  0.0376 mg/kg and Cd 0.0219 mg/kg (muscle). Water quality parameters were as follows: pH 6-6.7, temperature 28-33°C, DO5.42-7.14, brightness 1.5-2.5 m and depth 22-55 m. Based on data obtained, it can be concluded that the heavy metals content in fish, in the water and sediment were relatively low. Key words: Koto Panjang Reservoir, heavy metal, goramy fish

Abstract

AbstrakThe purpose of this study was to determine the proximate difference of instant shrimp paste shrimp paste (Acetes sp.) with the addition of different types of chili and to determine the level of consumer acceptance of making instant chili paste with different types of chili treatment. The method used is an experimental method by conducting experiments on consumer acceptance of the instant rebon shrimp paste chili with red and green chili types with a weight of 84,6,6g or 47% of the weight of the shrimp paste that you want to make. Parameters assessed by proximate and organoleptic analysis were appearance, aroma, taste and texture performed by 80 untrained people, moisture content, ash content, fat content, protein content and carbohydrate content. The results showed that making chili paste using red chili was more preferred by consumers than green chili chili paste. The formulation for making red chili paste with 33% water content, 77% ash content, 83.49% fat content, 46.18% protein content and 52.33% carbohydrate content.Keywords: Acetes sp, red chili, green chili, instant, shrimp paste.

Abstract

AbstractLubuk Siam Lake and Pinang Dalam Lake are oxbow lakes formed due to the interruption of the Kampar River flow. Fish is one of the aquatic biota which can be used as an indicator of the level of pollution that occurs in the waters. Asian Redtail Catfish (Hemibagrus nemurus) inland fisheries that has economic value and is often caught by fishermen around the lake. The purpose of this study was to determine the content of heavy metals Pb and Zn which accumulate in the skin, liver, and kidney organs of the fish in the two lakes. Organ samples were collected and digested according to standard procedures to determine the concentrations of heavy metals Pb and Zn tested using Atomic Absorption Spectrophotometry (AAS). The results showed that the highest and lowest heavy metals were in the organ of Asian Redtail Catfish in Lubuk Siam Lake, namely Pb (kidney> liver> skin) and Zn (kidney> liver> skin), while for Pinang Dalam Lake, namely: Pb (liver> skin). > kidney) and Zn (kidney> skin> liver).Keywords: Heavy metal,  baung fish, organs, Pinang Dalam Lake.

Abstract       Malong fish (Muraenesox cinerus) is a demersal fish that has important economic value and provides large contribution in the number of fish catches in the Bengkalis Regency. The purpose of this research is to find out the growth and exploitation rate the fish in the Bengkalis waters. This research was conducted in May-July 2020 and fish samples were collected from the fish landing place located in the Meskom Village. Data were analysis by aELEFAN I method (Electronic Lenght Frequencys Assesment Tool) from the FISAT II (FAO-ICLARM Fish Stock Assesment Tool) software. Muraenesox cinerus captured were 82 samples consisted of 34 males and 48 females. The length frequency distribution of the female fish shown that the most common fish were around 149-161 cm TL, while that of the males were 142-153 cm TL. The length-weight relationship of male was negative allometric and female was negative allometric. The growth coefficient (K) of the male fish was 10/year while that of the female was 5.01/year, the infinitive length (L∞) of male was 201 cm and that of the female was 213 cm.  The theoretical lifespan (t0) of male was -0.0086/year while that of the female was -0.0174/year.  The Von Bertalanffy growth equation of the male was Lt=201(1-e-10(t+0.0086)) and that of the female was Lt=213(1-e-5.01(t+0.0174)). The estimated natural mortality (M) of the female was 2.94/year, the mortality due to catching activity (F) was 4.51/year. The suspected natural mortality (M) of the male was 4.70/year, the mortality due to catching activity (F) was 20.26/year. The exploitation rate (E) of the male was 81% and that of the female was 61% or already exceeds the optimum exploitation value limit of 50%.Keywords: Exploitation Rate, Growth Pattern, Long-Weight relationship, Mortality, Silver conger, Von Bertalanffy
