Abstract

Blitok Village at Situbondo Regency is a village that borders directly on The North of the Java Sea. Fishermen use handlines and shrimp nets because of a low budget and ease of operation. These fishing gear are considered environmentally friendly. At that time, data and information regarding these fishing are rather specific. Therefore, this research aims to dig into the use of these fishing gear from ecological, economic, and social aspects. Ecological aspects will be using CPUE Analysis. We discuss economics with the use of Financial Analysis. The Perception Analysis is used for the social part. This research was carried out by census because the population observed was 16 fishermen. The observations showed CPUE values ​​were not good enough. It was also confirmed by financial analysis results. As a project, this business activity is not feasible. However, until now, this activity is still carried out by fishermen. Even though, 50% of fishermen admit that their condition is still less than prosperous. 75% of fishermen agree that this activity is Just Enough to support family income.

Abstract

Coastal areas face threats from hydro-oceanographic activities and human actions, leading to disasters such as extreme waves and coastal erosion. In Indonesia, particularly in Teluk Pakedai sub-district, these issues are prominent. Effective mitigation strategies tailored to the region's characteristics are essential. This research aims to analyze extreme wave and abrasion threats in Teluk Pakedai and develop mitigation plans. Using the Indeks Ancaman Bahaya Gelombang Ekstrim dan Abrasi (GEA) method outlined in BNPB's 2012 guidelines, factors like wave height, ocean currents, beach typology, vegetation, and coastline shape will be assessed and mapped using ArcGIS. From 2018-2023, significant erosion and accretion were observed, with the highest erosion in Kuala Karang Village (16.93 Ha) and the most accretion in Tanjung Bunga Village (57.79 Ha). Seven villages face medium to high danger from these threats. Recommended mitigation strategies include mangrove planting, constructing breakwaters, establishing early warning systems, and enhancing public awareness of extreme wave and abrasion risks.

Abstract

The existence of artificial reefs in coastal areas is used to repair damaged habitats by simulating the ecological role of natural coral reefs. The selection of placement locations under the sea is done so that artificial reefs can function properly. The purpose of this study was to determine the influence of hydro-oceanographic characteristics on the placement of artificial reefs that have been carried out in several coastal areas in Indonesia. This research is expected to provide an overview of the effectiveness of artificial reef placement towards efforts to repair damage to the coastal ecosystem. Artificial reef data was obtained in coastal waters located in Java and Sulawesi Island. Review of the application of artificial reefs includes placement location, hydro-oceanographic data, and evaluation of the existing condition of artificial reefs after the sinking period. The review of the relationship between the initial data and the existing condition of artificial reefs after the sinking period at the placement site against the hydro-oceanographic characteristics of the respective coastal water location. The success of artificial reef placement as a coastal ecosystem restoration effort is strongly influenced by bathymetry contours, wave height, current speed, and sedimentation.

Abstract

Bengkunat and Ngambur districts are located in West Pesisir Regency, Lampung Province, these are located on the southern coast of the island of Sumatra. Tsunami disasters can occur at any time if there is a generator such as a seafloor earthquake and cannot be predicted when it will occur and will be destructive or not. This research is modeling wave propagation using COMCOT program to determine tsunami wave propagation, run-up, arrival time and inundation. The magnitude scenarios used are 6.5, 7.5 and 8.5. Tsunami waves in Bengkunat and Ngambur districts showed destructive tsunami potential in each scenario. Wave height, wave inundation area and wave arrival time vary due to differences in magnitude as well as the geographical conditions of the coast and its bathymetry. The higher the magnitude, the higher the wave height and the faster the arrival time. Pagar Bukit, Suka Negara, Muara Tembulih and Sumber Agung are villages with significant damage because the wave height is above 8 m with arrival times ranging from 29-34 minutes. While Padang Dalam, Gedung Cahaya Kuningan and Parda Suka, the wave height is between 2-6 meters with a time ranging from 35-39 minutes, Inundation at magnitude 6.5 only hits the coastal area only as far as 220 meters, but at magnitude 7.5 inundation reaches about 2.4 kilometers while at magnitude 8.5 inundation reaches 3.4 kilometers.

Abstract

The main engine of a ship plays a crucial role in supporting its operations. Failure in this engine can have fatal consequences, both in terms of safety and economic impact. This study applies the Failure Mode and Effect Analysis (FMEA) method to the main engine of Ship XYZ to identify potential failure modes and calculate risk levels based on the Risk Priority Number (RPN). Operational data, interviews with the chief engineer, machinists, technicians, and historical failure analyses were used to assess the parameters of Severity (S), Occurrence (O), and Detection (D). The results indicate that fuel pipe leakage has the highest RPN value (405), followed by rotor damage in the turbocharger (245), and mechanical failure in the valve (224). Recommended improvements include enhancing maintenance of the fuel pipe system and conducting regular visual inspections, routine cleaning and lubrication, vibration inspections for turbocharger components, as well as using high-quality lubricants and cleaning carbon residue buildup on intake valves. Keywords: FMEA, Main Engine, Potential Failure, Ship, RPN.

Abstract

One of the procedures for rescuing a seaplane after an operational is to secure it, namely by mooring at an available port or mooring at a mooring buoy. This mooring buoy is considered a vehicle necessary for securing seaplanes in coastal conditions where it is not yet possible to build infrastructure in the form of an amphiport. To overcome this problem, seaplanes need to add a mooring cleat at the end of the bow of each float, which attaches the rope to the mooring buoy itself. So, it is necessary to study the strength of the mooring cleat itself when withstanding environmental loads. This study was carried out by modelling the mooring cleat using the finite element method to determine where the most significant stresses occur in the mooring cleat structure. Mooring cleats are modelled on deck thickness with varying thicknesses of 20mm and 40mm. The stress that occurred in the mooring cleat structure is then calculated using the Palmgren-Miner rule to determine the fatigue life of the mooring cleat for each variation. It was found that the largest von Misses stress experienced by the structure using 7075-T6 aluminium material was 147.87 MPa, which occurred in the mooring cleat, which was located on the 20mm deck thickness variation at the portside. Meanwhile, this variation's most extended fatigue life calculation occurred for the 40mm deck thickness variation on the portside with 514.43 years.

Abstract

Windlass machine is a tool on a ship that is used to pull and lower anchors and is usually also used to moor ropes when the ship is docked at the dock. In its operation, this windlass machine consists of an anchor, anchor chain, windlass, hydraulic pump, electric motor. The hydraulic pump functions to convert mechanical energy into hydraulic energy by pressing the hydraulic fluid in the system to drive the main shaft of the anchor machine, to make it easier for the crew to lego and hibob anchors. If in a less than optimal condition, it will disrupt the performance of the windlass and cause damage and shorten the service life. This happens because there is no maintenance and repair to avoid damage, especially to the hydraulic pump. This study aims to ensure that the performance of the windlass in its supervision and operation remains optimal in ship service.
