Abstract

A study on fish enlargement in the static floating cage system aquaculture(FCSA) has been conducted in November 2014 in the Sedanau Village, BunguranBarat Sub-District, Natuna. This research aims to understand the prospect the businessbased on various investation criteria. The type of fish cultured were tiger grouper,grouper, humpback grouper and napoleon wrasse. Results shown that the amount ofinvestment for nine bags was Rp 204.55 million, seven bags was Rp 175.55 millionand 5 bags was Rp 141.2 million. The allocation fixed capital was 60% for boatpurchasingh, 25% for nets and 10% for other needs. The working capital was allocatedfor seed (45%) and feed (43%). Results of the investment analysis criteria such asRCR, FRR and PPC shown that the FCSA business with 5 bags per unit is better thanthe 7 and 9 bags per unit. The prospect of FCSA business is very good in terms ofmarketing and availability of food, but in the future, it may be difficulies in obtainingthe natural fish seed.

Abstract

In the Siak River, Riau, the water quality in the downstream area is relativelybad due to pollutant originated from several sources such as industrial and domesticwastes. The low quality water may negatively affects the growth of fish and it isreflected in the growth pattern in the otolith of fish living in that river. To understandthe 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 ofthe Siak River. The otolith were then removed and processed following Windarti(2007)and investigated under a binocular microscope to study the growth ring patternin the otolith. The number of dark growth ring was counted. Results shown that 2 to 5dark growth rings, around 0.086 mm thick were present in the otolith of the fish. Thepresence of the dark growth rings in the otolith indicated that the growth of P. grootiin the downstream of the Siak River was hampered and this fact also suggested that thewater quality in the downstream of the Siak River is not sufficient to support the life P.grooti in that area.

Abstract

Accuration for preparing budget to estimate contruction costs greatly affects thesuccess of its funding. In addition, this will effect the successfull of its building. Inboatbuilding project, this will monitor the initial funding ability. Therefore,preparation of Cost –Budget Plan (RAB) can be as a solution to describe total cost inboatbuilding as material cost, cost of manpower, etc. The aim of this research is togenerate application of RAB for Bagansiapi-api shipyard by using Macros Excel. It isdeveloped by using prototype methods with visual basic for application (VBA).Results shown that the resulting aplication can help in processing the boatbuildingcost .

Abstract

Climbing perch is one of fresh water fish that has been started to be cultured, howeverthere are some problems occur such as low growth rate and high price of feed. Biofloc is atechnology that use bacteria which is able to destroy the waste and to maintain the water quality.Floc can be used as feed as well. This technology is capable to be applied even in the highdensity of fish rearing.T he aim of this research was to study the effect of biofloc technologyfor climbing perch culture with different densities. This research was conducted in the Muliasarivillage, Banyuasin District, South Sumatera Province since February to April 2015. TheCompletely Randomized Design (CRD) with five treatments and three replications wasapplied. The treatments were A : 100 fish/m2of density without biofloc technology, B : 100fish/m2of density with biofloc technology, C : 200 fish/m2of density with biofloc technology,D : 300 fish/m2of density with biofloc technology, E : 400 fish/m2of density with biofloctechnology. Results shown that the addition of biofloc provide significantl effect on floc, fishgrowth and feed conversion ratio. The best density was 400 fish/m2 with 5.8 mL/L of floc andfood conversion ratio 0.81, survival rate 73%, growth weight 2.77 gram and legth of 1.87 cm.

Abstract

The research was conducted on January 2015, in the waters of the Sungai Bela Estuary,Indragiri Hilir Regency, Riau Province. The research purposed was to define the habitatcharacteristics, vertical distribution, and analysis of correlation between habitat parameters andabundance of windowpane oyster (Placuna placenta). There were 4 stations and each stationdivided into 3 sampling points based on the depth, they were <2 meter, 2–4 meter, and >4meters. Results shown that good habitat characteristics for windowpane oyster was ontemperature of 27.77 0C, Total Suspended Solid on 24.33 mg/L, current speed on 0.02 m/s, pHon 7.87, salinity on 20.60/00, DO on 7.63 mg/L, BOD on 4.17 mg/L, Nitrate on 0.07 mg/L,phosphate on 0.05 mg/L, and organic on 30.07%. The highest abundance of windowpane oysterwas on station 4 (11.000 Ind/Ha). While in vertical term, the highest abundance was at <2meter depth. The distribution pattern of windowpane oyster was evenly at station 1 andclumped in station 2, 3 and 4. Result of correlation abundance of windowpane oyster effect oncurrent speed was r= -0.711, pH was r= 0.649, the abundance of phytoplankton was r= 0.688,and mud substrate was r= 0.535.

Abstract

In many coastal waters, including in the Kwandang Bay, often there are threeinterrelated ecosystems, they are mangroves, seagrass beds and coral reefs ecosystems.This study aims to determine the existence of mangrove ecosystems in the KwandangBay waters, and to determine the condition of the ecosystem based on the communitystructure. This research was conducted in the waters in the Kwandang Gulf of NorthGorontalo District for three months. The method used in this research was a surveymethod, and purposive sampling was conducted to collect the data. Six samplingstations with 20x20 m2 transect areas were determined to collect the mangroveecosystem data. Mangrove species found were Shoneratia alba, Brugeiragymnorrhiza, Xylocarpus sp,, Cariops tagal, Rhizophora sp, and Avicenia sp. Themangrove ecosystem has low diversity level, evenly distributed species, and there is nodominant species.

Abstract

A research aims to understand the effectiveness of the use of palm (Elaisguineensis) shell as biofilter media in the aerobic system to decrease the ammonialevel in the tempe industry liquid waste has been conducted in the Tuah Karya Village,Pekanbaru. Results shown that during the seeding period, the value of ammonia was23.37-39.12 mg/L in the inlet. During the research period, the ammonia value was19.78-27.63 mg/L and by using the palm shell, the value was 25.52-39.48 mg/L in theinlet and 18.85-30.64 mg/L in the outlet. Without using the palm shell, the ammoniavalue was around 33.12-41.35 mg/L in the inlet and 28.17-34.69 mg/L in the outlet.Based on the results obtained, it can be concluded that the used of palm shell iseffecient to decrease the ammonia level in the tempe industry liquid waste.
