Abstract

The aim of the research is to describe the blood of Tilapia that had been cultured in a fishpond since June to December 2015. The ponds were located in Marpoyan Subdistrict, Pekanbaru city. Twenty samples were collected as much as 20 fish that consisted of 10 male and 10 female with the size ranging from 9.5 – 18.2 cm. The blood of the fish was taken with syringe via caudal vena as much of 1 ml. The blood parameters then were calculated in term of the number of hematocrit, leucocyte, erythrocyte, and leukocyte. The results showed that the amount of hematocrit and leukokrit were ranged between 10 – 31 % and 1.78 – 3.10 % consecutively. The total cell of erythrocyte ranged between 1,170,000 – 2,190,000 cell/mm3, and the total of leukosit were about 81,000 – 105,000 cell/mm3. In addition, the types of leukocyte found at this study were hepatocyte (53- 86%), thrombocyte (25 – 39%), monocyte and neutrophil between 1 – 3 %.

Abstract

In the Siak River, Riau, the water quality in the downstream area is relatively bad due to pollutant originated from several sources such as industrial and domestic wastes. The low quality water may negatively affects the growth of fish and it is reflected in the growth pattern in the otolith of fish living in that river. To understand the growth pattern in the otolith of Pristolepis grooti (Anabantidae)living in that river, a study has been conducted. Totally 25 fishes were captured from the downstream of the Siak River. The otolith were then removed and processed following Windarti (2007) and investigated under a binocular microscope to study the growth ring pattern in the otolith. The number of dark growth ring was counted. Results shown that 2 to 5 dark growth rings, around 0.086 mm thick were present in the otolith of the fish. The presence of the dark growth rings in the otolith indicated that the growth of P. grooti in the downstream of the Siak River was hampered and this fact also suggested that the water quality in the downstream of the Siak River is not sufficient to support the life P. grooti in that area.

Abstract

Difficulties to obtain good wooden materials as vessels primary materials conduce to drop the quality and the lifetime of a ship. To satisfy new ship building demand, a shipyard tends to apply fast building and ignores the ship quality, types, and dimension and materials characteristics. Shipyard also did not consider about the technical and operational aspects as rule and regulations for wooden vessels. Un-optimal ship construction make it low in quality and at the end, it cannot be used directly after handover. In general, the cause of damage of ship was due to unsatisfying of construction criteria such as the types of wood, including the age and the length of the wood used for its construction. In addition, it had been found that there were unsatisfied ships operating under construction regulation.

Abstract

Mudskipper or Periopthalmus variabilis Eggert (subfamily Oxudercinae, Gobiidae) commonly present in the intertidal area of mangrove ecosystem. This fish is able to walk in the forest floor by using its pectoral fins. To understand the gonad development and fecundity of the fish, a study has been conducted in September - October 2014. The fish was sampled by scoop net at night. Results shown that the male-female ratio 2 : 1. The males were in the 1st to 4th maturity levels , while those of the females were in the 3rd, 4th and 5th levels. The fecundity was ranged from 112,496 – 137,698 eggs/fish.

Abstract

This study aimed to analyze the financial feasibility of fish catching in Koto Panjang Reservoir of Kampar District, Riau Province, using business and investment criteria analyses. The result showed that each engine boat and rowboat has IDR 29,313,301.59 and IDR 15,044,311.11 for their respective profit; 3.55 and 3.48 for their respective Revenue-Cost Ratio Value; 0,29/yr or 3.3 months and 0.30/yr or 3.6 months for their respective fishermen payback period; and 3.6 % and 4 % for their respective Return on Investment (ROI) value. Investment criteria analysis on fish catching for each engine boat and rowboat obtained Net Present Value (NPV)of 142,169,973.13 and 72,313,686.96, respectively; 3.01 and 2.91 for their respective Net B/C value; 49% and 46% for their respective Internal Rate of Return (IRR) value. Fish catching business in Koto Panjang Reservoir is deemed feasible because NPV>0, IRR>interest rate, and B/C>1 for both engine boat and rowboat

Abstract

The power requirement of ship must comply its form and principle dimension to make efficient fishing operational cost. To estimate power requirement of a ship conducted by vary approach such as Guldhamer Methods. Manual calculation by using this methods somewhat sophisticated and not practical since can only be done by certain people. Thus, to make it more simple, all the patterns are modified to be Matlab Graphical User Interface. The result shows that scoop netter power is 25,0754 HP calculated by using Matlab Application, meanwhile in the real condition the magnitude of fisher fishing vessel is 26 HP. There was discrepancy approximately about 4% where it was caused by measurement calculation in the field. Thus, this application can be used as a reference in calculation power requirement of a fishing vessel.

Abstract

Research of toxicity of industrial palm oil wastewater and sub lethal test to Oreochromis sp. has been conducted on February 1st to March 1st 2009 in Aquaculture Technology Laboratory, Fisheries and Marine Science Faculty University of Riau. Objective of this research is to determine the concentration of a test material or the level of an agent that produces a deleterious effect on Oreochromis sp. during a short-time exposure under controlled condition. In this study, static 96-h acute toxicity tests were carried out using Oreochromis sp. as test organisms. Probit analysis using the computer software EPA and graphical method were used to caculate the 96-h LC50 depending on data suitability. Results of the 96-h LC50 and Biological Savety Level of the industrial palm oil waste water were 126,06 ml/l and 1.26 ml/l respectively.

Abstract

This research was conducted in the laboratory of waste Processing Technology and the laboratory of Water Quality Management in the FAPERIKA – UNRI. The aim of this research is to identify the ability of chitosan in reducing the level of TSS in the wastewater of plywood industry. The method used in this research is  experimental study with completely randomized design, one factor, 4 level, 12 units of trial. Several concentration of chitosan such as 0 mg/L, 15 mg/L, 30 mg/L were applied on the wastewater and observed after 8 hours, 12 hours and 16 hours. The result shown that 12 hours after addition of 30 mg chitosan /L, the quality of the waste improved : TSS 182,3 – 56,7 mg/L, Phenol 2,4 - 0,5 mg/L, BOD5 132-93 mg/L, COD 279-217 mg/L and pH 6 - 9.
