 ABSTRACT    This research was conducted from April to June 2018 for 42 days at the TIU Improvement (Technical Implementation Unit) Faculty of Fisheries and Marine Science, Riau University. The purpose of this study is to in vestigatedifferent form of container with recirculation systems. Water treatment from tarpaulin with a capacity of 80 L in air volume. Fish stock was 20 fish/tank. The research method was the experimental method with 4 treatments and 3 replications. Treatments was : P1= Circle Shape, P2 = Square Shape, P3= Leg Length and P4= Triangle Shape. The results of this study can be concluded that the different forms of container are not significant to the growth of red tilapia, but the forms of containers are significantly different for the survival of red tilapia. Growth performance of round shape, square shape, rectangular shape and triangle shape, each of which has given weight growth 9.12 g; 10.04 g; 8.95 g; and 8.49 g, then the growth of a double length of 4.30 cm; 4.56 cm; 4.13 cm; and 4.03 cm, daily growth rate of 4.29%, 4.67%, 4.43% and 4.34, feed feed 82,04%, 91,47%, 83,61% and 79,66%, and the rate of life is 85.00%, 96.66%, 90.00% and 85.00%. The measurement results of water quality are still in the optimal range in the maintenance of red tilapia, namely temperatures of 26-29.3 ° C, pH 6.3-6.8, DO 4.5-6.1 mg / L, and ammonia 0.26- 0.17 mg / L. Keywords : Oreochromis sp, recirculation system, different shape of tank survival rate

Abstract

ABSTRACTPeriphyton is a sessile microscopic organism that attach on submerged substrates. A research aims to determine the type and abundance of periphyton attached in theusedtyre pieces placed in the Air Hitam River substrate has been carried out in April-May 2018. There were three sampling stations, namely S1 (in the upstream), S2 (in the middle) and S3 (in the downstream). Samplings were conducted once/week for a 3 weeks period. The periphyton samples are brushed from the used tyre substrates (8 x 6) cm2. The number of tyre pieces in the S1, S2 and S3 were 12, 9, and 6 pieces respectively. Water quality parameter measured were water current, temperature, transparency, pH, dissolved oxygen, free carbon dioxide, nitrate, and phosphate. Results shown that there were 29 types of periphyton present and they were belonged to 4 classes, namely Bacillariophyceae (15 species), Cyanophyceae (3 species), Chlorophyceae (8species), and Euglenaphyceae (3 species). The abundance of periphyton in the tyre substrate in the S1 was 15.119 cells/cm2, in the S2 was 37.245 cells/cm2and in the S3 was 70.029 cells/cm2. The water quality parameters were as follows: water current 0.08-0.46 m/s, transparency:18-29 cm, temperature 29-29.3oC, dissolved oxygen 3.43-3.56 mg/L, free carbon dioxide 6.2-7.9 mg/L, nitrate 0.302-0.529 mg/L, phosphate 0.348-0.542 mg/L. Data obtained indicate the the water quality of the Air Hitam River  is suitable to support the life of periphyton. Keywords:Type and abundance, sessile organism, aquatic algae, rubber subtrate

Abstract

AbstractPalm oil liquid waste is rich in TSS and ammonia and thus need to be processed before being flown to environment. A study aims to reduce the TSS and ammonia in that waste by using a biofilter that was added with EM4 has been conducted in March-April 2019. There were 3 treatments applied, namely the addition of  12 ml, 15 ml and 18 ml EM4 in the anaerob and aerob tanks, 3 replications. The waste was settled for 3 days in the anaerob and 3 days in the aerob tanks. The treated waste was then tested for TSS and ammonia concentrations. The treated waste was also used for rearing Pangasius sutchi seedlings. Result shown that after being treated using the EM4 enriched biofilter the TSS reduced into60-71.66 mg/L and ammonia was 2.5047-5.3624 mg/L. The survival Pangasius sutchi seedlings reared in the treated waste was 66.66-93.33%. The best treatment to reduce the TSS was the addition of 15 ml EM4 and the effectiveness was 60 mg/L while that of the ammonia was 2.5047 mg/L. It can be concluded thatthe addition of EM4 to the biofilter tanks was able to reduce the TSS and ammonia in the palm oil industrial liquid waste. Keywords: Waste water, Effective Microorganism-4, Pangasius sutchi, Biofilter System.

Abstract

Abstract This research was conducted to measure the level of productivity in ship repair activities and determine the factors that influence the increase in productivity in ship repair activities. This research was carried out in April until May 2018 at the shipyard of the Palabuhanratu Fishing Port, Sukabumi Regency, West Java Province. The method used is a survey method by knowing directly the productivity of reparations in shipyards. Reparation is an overall activity about repairing a ship, starting from the collision on the part of the ship that is leaking, painting, replacing weathered wood, cleaning the hull skin and repairing the damaged engine. Productivity is a comparison between spending and input. The factors that most influence the shipyard productivity from the measured performance indicators are the number of employee absenteeism or labor where the importance of the weight is 30%, the ship repair workforce and effective working hours which have a weighting of 20% each. Based on the results of the measurement of performance indicators for 5 years with the Objective Matrix method, the productivity index of performance indicators from 2013 to 2017 has experienced a considerable decline due to the decreasing number of vessels carrying out ship repairs. Keywords: Ship Repair, Productivity, Measurement of Performance Indicators
