Abstract

In recent years, trade traffic through Tanjung Priok Port has always increased. An increase in the economy always has a negative impact on the environment. Because every ship that docks has the potential to dump waste in the port area. Most of the causes of marine pollution in Indonesia are caused by ship waste, of course this is related to the lack of awareness of ship operators about the cleanliness of the environment around the port. Related to this, this research was conducted to plan an environmentally friendly Oil Spill Recovery Boat, by using electric power for navigation and communication needs. Oil spill control vessel design. This Oil Spill Recovery Boat has a catamaran hull designed using the Maxsurf application. The method used to determine the main size of the Oil Spill Recovery Boat is linear regression, namely by using comparison vessels that have been compiled and then adjusted to the number of oil spills in the research area. By using Maxsurf software, the main dimensions obtained are L = 10.0 m, B = 4.42 m, H = 1.34 m and T = 0.61 m.. This ship has a crew of 3 people.

Abstract

Coastal damage caused by sea wave attack has increased significantly recently. This will have an impact on the loss of residence and economic resources of coastal communities. In some incidents it has even claimed lives. Therefore, it is necessary to build a sea wall that can withstand the attack of sea waves both for short wave types and for long sea wave types which are usually provoked by storm winds. In this study a seawall type with double chambers was tested. From the test results it can be seen that this type of seawall is effective in being able to withstand attacks by sea waves both short and long seas because of the existence of double spaces that can expand the range of wave frequencies so that wave height can be reduced constructionally. In this study it has also been confirmed that the wave amplification value is around 2.5 times the incident wave height, which means that the wave energy in the seawall chamber can be utilized. -spasi-Times New Roman 11 Italic- Keyword: Beaches, Waves, Seawalls and Wave Amplification

Abstract

The territorial waters of West Aceh, Aceh Province is an area with a long topography and wide sea. The water area is included in the Republic of Indonesia State Fisheries Management Area (WPPNRI) 572. The hammerhead shark Sphyrna lewini is not significantly different from the hammerhead shark Sphyrna mokarran, both of which are characterized by their heads widening laterally and being less than a third of their body shape. Sphyrna lewini has a body size ranging from 50 cm to 420 cm, which generally lives in the tropics and is easily found in island waters with a continental shelf reaching a depth of 275 m. Its important role can be seen from an ecological perspective in the development of conservation and sustainable marine and fishery resources. This should be managed responsibly for the sake of creating a prosperous and independent society. West Aceh district is a coastal area that is rich in fishery products. This is inseparable from its location directly facing the Indian Ocean which is rich in fish. However, the sustainability of the hammerhead shark is not yet known in detail. Therefore, a study on the sustainability of hammerhead sharks at PPI Meulaboh needs to be carried out. The method used in this study was a field experiment (experimental fishing) from fishermen’s catches. Furthermore, the data obtained were tabulated and analyzed. Overall, the size of the hammerhead shark caught by fishermen was in the interval of 62.5-93.5 cm. By sex, there were 19 male sharks and 20 female sharks. The maximum length (L∞) was 96 cm. Furthermore, the value of K was 0.290 per year. The Von Bertanlffy growth equation model was Lt = 91.6(1-e-0.29(t+0.03)). The value of total mortality (Z) was 0.84 and natural mortality (M) was 0.94 with a temperature of 29 0C, where the incidence of natural deaths was greater than fishing deaths. Fishing mortality (F) was 0.10, with an exploitation ratio (E) was of 0.12.

Abstract

OT ship. Skylie is a type of tanker produced by PT. Samudra Marine Indonesia, in its construction, applies a keel cooler as a cooling device for the main engine propulsion of ships. This keel cooleris one of the new types of heat exchangers which is applied in the field of shipping. A cooling system using a keel cooler is a closed-circuit cooling system that is installed externally on the hull below the waterline. This study aims to determine the overall heat transfer value and the effect of changes in ship power/torque on the effectiveness of the keel cooler-type heat exchanger. The analysis uses two methods, namely CFD analysis and simulation using the Ansys CFX R20 application. Based on the results of calculations on several ship power/torque conditions, the largest heat transfer value is obtainednamely 5.599 x 10 5 W at 100% power condition and the lowest value is 5.055 x 105 W at 10% power condition. Meanwhile, the highest effectiveness value is 79.985% and the smallest value is 79.839%. So it can it was concluded that the use of the keel cooler on the OT ship. Skylie has met the standard value of effectiveness for a heat exchanger that is equal to 50%.

Abstract

Increasing the cooling capacity of generator engines or condenser engines by utilizing sea water at PLTU Barru requires dredging the intake channel with a dredging length of ±80 m and a depth of -4m LWS. The problem is that dredging the intake canal has the potential to cause silting back in the area that has been dredged due to coastal hydrodynamic processes which can cause blockage of the intake canal and disrupt the process of the pumping system and the generating system as a whole. A study is needed to assess the potential for sedimentation around the dredging area. This research uses primary data and secondary data. The primary data consists of bathymetry data, currents, tides and bottom sediments and water samples. While the secondary data includes comparative wave and tidal data as well as the design of the dredging plan. Wave data is sourced from the European Center for Medium-Range Weather Forecasts (ECMWF) while comparative tide data is obtained from the Geospatial Information Agency (BIG). The data obtained is then analyzed to obtain the parameters of currents, tides, sediment and breaking waves as well as sediment transport along the coast. Calculation of sediment flows and transport was also carried out by numerical modelling using a surface-water modelling system (SMS). Furthermore, by using the results of analytical sediment transport analysis and numerical modelling, the thickness of the trapped sediment is calculated in the intake canal after dredging. The results of numerical modelling analysis show that the potential for sedimentation at the study site originates from currents due to tides and currents due to breaking waves. The predicted potential for sedimentation due to tidal currents and broken wave currents for 1 year is 43.64 m3 and 1,589.93 m3 respectively with a sediment thickness of 1.2 meters from the bottom of the excavation so that intake channel maintenance is required at least once a year.

Abstract

Fishermen are very dependent on the season. Measuring the welfare of fishermen requires indicators that are quick and precise to see a picture of the welfare that has been achieved. One indicator that is believed to be used to see household welfare is the Fishermen's Exchange Rate (NTN) indicator. The purpose of this Fishermen's Exchange Rate research is to find out the characteristics of fishermen and the achievement of Fishermen's Exchange Rates in Situbondo Regency so that it can be used to provide input in the formulation of targets and formulation of policies to improve fishermen's welfare. The method used in this Fishermen Exchange Rate research is a survey. The number of respondents in the Fishermen Exchange Rate (NTN) Study was 189 respondents. The characteristics of the respondents in this study include the age group and educational level. Characteristics of fisherman respondents by age group consisted of 43% of fisherman respondents in the age group of 41-50 years, 22% in the age group of 30-40 years, 20% in the age group under 30 years and at least 15% in the age group of 51-60 years. The results of the analysis of the characteristics of fisherman respondents based on their level of education showed that the majority of respondents graduated from elementary school (SD) and below, namely 69%, 23% graduated from junior high school (SLTP) and only 8% had attended senior high school (SLTA) education. The NTN value of Situbondo Regency for the period January - October 2022 is 1.043 or the NTN value is around number one, which means that fishing families in Situbondo Regency in 2022 are only able to fulfill their daily needs and are categorized as vulnerable to poverty and are not yet able to consume secondary or tertiary needs, to save in the form of investment goods.
