Abstract

ABSTRACTFish production landed in Sungailiat VAT in 2017 was 4,419,520, kg while in 2018 an increase of 4,936,332 kg from the data showed that the Sungailiat port had a large potential for capture fisheries.  However, the great potential of fisheries has not been supported by optimal port facilities and maximum management, some of the facilities in Sungailiat VAT are not functioning such as ice picking facilities, fish packing or storage buildings and fishing nets or fishery resting buildings.  This study aims to determine the condition and level of utilization of functional facilities.  This research was conducted in May 2019 at PPN Sungailiat.  The method used in this study is a survey method, by observing and collecting data directly about the utilization of Sungailiat VAT functional facilities, the utilization level analysis is used to determine the level of functional facility utilization.  The results obtained by the level of utilization of functional facilities in Sungailiat PPN which can be counted only 3 facilities namely, freshwater facilities (SWRO), the utilization rate is 11.27% (very underutilized), the utilization rate of electricity installation facilities is 79.24% (utilized with  good), while the level of utilization of BBM facilities is 40.34% (sufficiently utilized properly).  These results can be concluded that the level of functional facilities utilization in Sungailiat PPN is still classified as not good.  there is a need for better port development planning to restore untapped facilities such as ice factories, fish packing and storage buildings as well as fishing nets and resting buildings.Keywords: functional facilities,archipelago fishing port sungailiat, level of utilization

Abstract

ABSTRACTDinoflagellate isa large of microalgae groups. Its abundance was dependent on nitrate and phosphate content. The research was conducted in September 2018 that located at waters of Poncan Gadang Island, Central Tapanuli Regency. The aims of this research was to analyze nitrate and phosphate content, identification of species of epiphyte dinoflagellates, and the relationship between nitrate and phosphate content with abundance of epiphyte dinoflagellate on seagrass Enhalus acoroides were analyzed. Apparently the highest of nitrate content found at station I and II on 0.0402 mg/l, the lowest found at station III on 0,0367 mg/l. the highest of phosphate content found at station III on 0,0995 mg/l, the lowest found at station I on 00678 mg/l. It revealed that 3 species of epiphyte dinoflagellate foundwhich are Amphidinium sp., Gambierdiscus sp. and Prorocentrum sp. The highest of abundance epiphyte dinoflagellate found at station II on 1245,90 sel/g and the lowest found at station III on 767,13 sel/g. The relationship between the nitrate content with abundance of epiphyte dinoflagellate has a positive relationship with the regression equation y = 294.55 + 1121.5x, while the relationship between the phosphate content with abundance of epiphyte dinoflagellate has a negative relationship with the regression equation y = 488.54 + (-1801.7x).Keywords : Epiphyte Dinoflagelates, Nitrate , Phosphate, Poncan Gadang Island.

Abstract

ABSTRACT The aim of the study was to determine the optimal doses of boster grotopin increasing the growth and survival of baung fish (Hemibagrusnemurus) in the recirculation system. This research was conducted from Augustuntil October 2019 for 40 days at the Technology LaboratoryAquaculture Faculty of Fisheries and Marine Riau University. Which methodused in this study is an experimental method, usingComplete Random Design (CRD) with 5 levels of treatment and 4 replications.The treatments applied were: P0) 0 g / kg of feed; P1) 15 g / kg of feed; P2) 20 g / kg of feed; P3) 25 g / kg of feed; P4) 30 g / kg of feed. The results showed thatthe addition of a different dose of booster grotopes shows a real effect(P<0.05) to growth in absolute weight (Wm), growth in absolute length(Lm), specific growth rate (LPS), feed efficiency (EP), feed conversion ratio(FCR) and have no significant effect (P>0.05) on the survival rate (SR)baung fish. The best treatment is giving grotop booster 30 g / kg of feed(P4) which produces an absolute weight growth of 3.86 g, long growthabsolute 2.41 cm, specific growth rate 1.62%, feed efficiency 83.55%, feed conversionratio 1.19% and survival 96.67%.Keywords:Doses,BosterGrotop, Recirculation System, Growth,Baung Fish.

Abstract

ABSTRACT Channa lucius is one of freshwater fishes that inhabit the Kampar Lama Oxbow Lake. This research aims to determine the type of food present in the fish’s stomach. To understand the type of food consumed by C. lucius, a research has been conducted at July to August 2019. There were 107 fishes captured, but only 38 fish have full stomach. The analysis was conducted using a gravimetric method. Stomach content was analysis as a basis to calculate the Preponderance Index (PI).  Result shown that the main food of C. lucius is fish (PI 98%) and the complementary food is insects (PI 1%). The water quality parameter of the Kampar Lama Oxbow Lake are as follows : temperature 28-29°C, transparency 47.5-48 cm, pH 5, DO 4.06-4.47 mg/L, and CO2 9.98-11.98 mg/L.Keyword : Channidae, gut content, gravimetric method, index of preponderance

Abstract

AbstractCarrying capacity is defined as the ability of aquatic environment to support the life of organism in that area. A study aimed to assess the aquatic carrying capacity based on chlorophyll-a for extensive fishing in the Tuok Tonga Lake, Buluh China Village,Siak Hulu Sub District, Kampar District, Riau Province.The carrying capacity was determined based on primary productivity using chlorophyll-a concentration, which is indicating the existence of phytoplankton in the water. This research was conducted in June-July 2019. There were 3 stations, namely Station 1 (inlet area), Station 2 (in the middle of the lake) and Station 3 (in the end of the lake). In each stations, there were two sampling point, in the surface and in 2 Secchi depth. Sampling was done three times once/week. Water quality parameters measured were chlorophyll-a, temperature, transparency, depth, pH, dissolve oxygen, CO2, nitrate and phosphate. Results shown that chlorophyll-a: 14.03-17.07 μg/L, transparency: 61.7-62.3 cm, temperature: 29.3-31oC, depth: 125-284 cm, pH: 5, dissolved oxygen:  3.37-4.94mg/L, CO2:5.32-11.98mg/L, nitrate: 0.02-0.08 mg/L and phosphate: 0.04-0.1mg/L. Based on concentration of chlorophyll-a indicates that the carrying capacity of the Tuok Tonga Lake for extensive fishing was 0.85 tons/year.Keywords: Oxbow lake, Primary productivity, Water quality

Abstract

ABSTRACTThe aim of this research is to find out how long the immersion effect of flax fiber on turi leaf extract is to determine the value of breaking strength and elongation of the fiber. The method used in this study is an experimental method that is by experimenting the length of time soaking hemp fiber in turi leaf extract as a fishing gear with soaking time for 0 weeks to 12 weeks. The value of breaking strength and elongation of the fibers were tested using Breaking Strength Tester. Data analysis using complete random design. The value of breaking strength of flax fiber that has been soaked has increased every week and the highest peak in the 9th week is 2.8 kgf / mm2 but in the 10th week through the 12th week has decreased. The value of flax fibers has increased unstable. The highest peak of elongation is at week 1 is 28.55 mm and the lowest stretch of flax fiber is at week nine which is 22.65mm. The results show that turi leaf extract is able to increase the breaking strength and elongation of flax fiber.Keywords: breaking strength, elongation, flax fiber,turi leaf extract
