Opis:
This study is carried out with the aim of developing sustainable port management in container terminals, allowing the volume of container traffic to grow, while at the same time reducing the consumption of energy and natural resources, the volume of waste generated and the negative impacts on social systems and ecosystems in the areas of influence of the port. The analysis of sustainability will be carried out using KPIs, which are management tools widely used by companies worldwide to measure and evaluate the performance of their processes and manage them in the most effective and efficient manner. As a main conclusion, it is indicated that it is not possible to reach the objective pursued of finding a relationship that could link the productivity indicators and the environmental indicators in the Spanish container terminals. The container terminals of the Spanish port system are heterogeneous, both in terms of operational management and environmental sustainability. They all operate with very different systems.

Opis:
This study aims to determine the method of generating water flow inside a round container to increase the survival and growth of common carp fingerlings. The approach used in this research is an experimental method which applies a Completely Randomized Design (CRD) and consists of three and five replications. The treatments used are (A) No Water flow (control), (B) 0.1 m/s of water flow, (C) Water flow utilizing an additional venturi system. The test fish used were 450 majalaya common carp of size 3-5 cm. The containers used in this research are in the form of 15 gallons capacity with a diameter of 27 cm x 36 cm height x bottom diameter of 6 cm containing 19 liters of water. The density of common carp during the study was 30 carp per treatment container. The treatment period is 40 days. The food given is 5% of the bodyweight of fish. Water quality parameters (temperature, pH, dissolved oxygen, ammonia and nitrates) were observed every 10 days for 40 days. Other parameters are survival, daily growth rate, feed conversion ratio, and feed efficiency observed every 10 days for 40 days. The results showed that the use of water flows with the venturi system provides the best results - with a life growth rate of 1.5%, a feed conversion ratio of 3.18, feed efficiency of 31.73% and 75% survival.

Opis:
This research aims to determine the best currents speed and utilization of venturi to increasing survival, growth of Cyprinus carpio L. and reducing the infection rate of A. hydrophila bacteria. fingerlings. This research used an experimental method completely randomized design (CRD) with four treatments and four replications. The treatments used were the use of currents and venturi on the maintenance media with currents velocities of 0 m/s (A), 0.06 m/s (B), 0.1 m/s (C), and 0.14 m/s (D). Maintenance of the test fish for 40 days then followed by a challenge test for 14 days. Koi fish fingerlings tested to use A. hydrophila with a density of 108 CF /ml. The parameters observed included white blood cells, red blood cells, clinical symptoms, survival, daily growth rate, feed conversion ratio and water quality. The results showed that the use of currents and venturi with a flow rate of 0.14 m/s was effective in improving the performance of the koi fish's immune system and reducing the infection rate of A. hydrophila bacteria. During the flow administration during the 40 days maintenance period, the white blood cell count increased by 20.51% from a value of 9.19 × 104 cells/mm3 to 11.56 × 104 cells/mm3. Red blood cells increased by 40.65% from 1.60 × 106 cells/mm3 to 2.69 × 106 cells/mm3. Currents treatment with a speed of 0.14 m/s produced the highest survival rate after challenged with a value of 86.7%. Also this treatment was effective in preventing infection of A. hydrophila bacteria, it can be seen from the macroscopic clinical symptoms that appear less than the treatment current. The best results of daily growth rate and feed conversion ratio provided in currents treatment with a speed 0.1 m/s.
