Abstract

Cilacap waters are said to be busy with sea traffic with many activities being carried out in the Cilacap water area. Environmental monitoring activities are needed to determine the existing conditions in Cilacap waters, in order to support smooth and efficient traffic activities in Cilacap waters. This study uses a method in producing a mapping of environmental conditions, namely by looking at the aspects of changes in coastline, water depth (bathymetry), wind direction, and velocity, as well as models of surface currents speed and direction in Cilacap waters. The results of this study indicate that the environmental conditions in Cilacap waters are still relatively not much different from the conditions in the previous year, namely 2017. The value of modeling ocean currents which are influenced by sea tides and ebbs has a relatively small value with values ranging from 0.1-1.5 m / s with an average speed of 0.4 m / s that occurs in June (east season). In June 2020 the wind in the Cilacap water area blows from the east and southeast with speeds ranging from 2.5 - 7 m / s. The bathymetry measurement results showed a result of less than -2 meters. These results also indicate a relatively gentle seabed slope with a maximum depth of more than -30 meters in Cilacap waters. This clearly shows that the morphology of the coast and the condition of Cilacap waters are not relatively significant, experiencing changes every year.

Abstract

Tegalsari Coastal Fishing Port (PPP) is a fishing area located in Tegal City and is a port with fairly dense ship activity. With the conditions owned in the Tegalsari PPP, it makes the Coastal Fishing Port with high economic potential. Conditions that affect activities at Tegalsari PPP are the silting of shipping lanes which cause sedimentation in the port pond or in the shipping channel. Therefore, information about bathymetry and sedimentation rate is needed to facilitate shipping flows at PPP Tegalsari. The purpose of this study is to identify hydrooceanographic conditions in Tegalsari PPP, analyze sedimentation rates in Tegalsari PPP and provide recommendations for the results of sedimentation rate analysis. The data used in this study contained 3 data, namely bathymetric data, tidal data and sedimentation rate data. For data processing using Mike 21 software. The results that have been carried out in this study have varied results on bathymetric conditions and sedimentation rates in Tegalsari PPP. The results of bathymetric modeling. In existing conditions PPP Tegalsari has an average depth of 1.2 – 3.6 m, in alternative 1 it has a depth of 3.0 – 7.2 m and in alternative 2 it has a depth of 2.5 – 7.0 m.

Abstract

Liquefied Natural Gas (LNG) is an alternative fuel with environmentally friendly solutions. In general, the domestic distribution of natural gas in LNG is more cost-effective than transporting gas through underwater pipelines considering Indonesia as an archipelagic country. However, the current challenge in the LNG industry is the lack of supporting facilities. Storage and regasification facilities are among the infrastructure that requires optimization. Floating Storage and Regasification Unit (FSRU) are viable options for energy distribution that offer opportunities and competitiveness compared to onshore terminals. Small and medium-scale FSRU can serve as an alternative solution due to their relatively fast, flexible, and affordable development process. FSRU is a facility that required fo alternative energy solution fo industry. In principal the FSRU vessel should be moored at the bow and the stern of the vessel for the sake of the stability of the vessel from the waves, tidal currents and winds, therefore not to disrupt the process of the gas production. Surrounding the FSRU vessel should be located the power plant facility and ISO Tank Conk Container Vessel. The viability analysis should be done to evaluate the FSRU Vessel berthing viability in the view of operational and financial at the Port or at the water.

Abstract

Terumbu karang adalah ekosistem purba, megah, dan tinggi produktivitas serta keanekaragamannya (Thomas dan Raymond, 2008). Terumbu karang bertumbuh setiap tahun dengan ukuran yang berbeda-beda tergantung pada kondisi lingkungan sekitar (Arman et al., 2013). Penelitian mengenai pertumbuhan terumbu karang sudah banyak dilakukan, namun prediksi pertumbuhan karang menjadi topik yang menarik dan belum banyak diteliti. Penelitian ini bertujuan untuk mengembangkan model pertumbuhan terumbu karang berdasarkan lingkar tahunan dengan metode logika fuzzy. Suhu permukaan laut (SPL) adalah salah satu faktor kunci yang mempengaruhi pertumbuhan terumbu karang (Westmacott et al., 2000; Sterr, 2001; Koontanakulvong, 2008; Thomas dan Raymond, 2008; Arman et al., 2013; Lalang, 2015). Analisis Indian Ocean Dipole (IOD) menemukan lima fenomena, ditandai oleh kenaikan SPL yang cukup signifikan. Lima fenomena tersebut terjadi pada tahun 1966-1967 (+IOD), 1969-1970 (-IOD), 1973-1974 (-IOD), 1983-1984 (-IOD), serta tahun 1987-1988 (+IOD). Hasil penelitian menunjukkan bahwa lingkar tahunan Porites lutea di stasiun sisi utara Pulau Tunda polanya mengikuti fluktuasi SPL. Stasiun di selatan Pulau Tunda yang berhadapan langsung dengan Pulau Jawa, polanya tidak mengikuti pola SPL. Stasiun di utara berbatasan langsung dengan perairan terbuka dan tidak terlindung dari pulau-pulau di sekitar. Simulasi pertumbuhan menunjukkan bahwa terumbu karang akan mampu beradaptasi terhadap perubahan iklim. Pada tahun 2085, terumbu karang bertumbuh dari -0,75 cm dan bergerak naik menjadi 0,1 cm di tahun 2100. Berdasarkan proyeksi SPL pada rentang tahun 1900-2100, anomaly SPL akan terus naik hingga mencapai 0,45 °C.

Abstract

Customer satisfaction is a feeling of pleasure or disappointment of a customer that comes from a comparison between his impression of the performance or results of a product and his expectations. Performance measurement is a method used to provide an assessment of how much the level of work performance or achievement of predetermined goals and objectives. Buy The Service (BTS) is a service purchase subsidy scheme by the government to the operator (private) in terms providing public transportation services with minimum service standards that must be implemented. Transpakuan has been officially operated since November 2, 2021, serving 4 corridors with a total of 49 fleets. One of them is corridor 1 (Terminal Laladon - Cidangiang). A satisfaction assessment is needed to see whether Biskita Transpakuan Bogor customers are satisfied with the service. The indicators used in the evaluation refer to the Regulation of the Minister of Transportation of the Republic of Indonesia Number 27 of 2015 concerning Amendments to the Regulation of the Minister of Transportation Number 10 of 2012 concerning Minimum Service Standards for Road-Based Mass Transportation. This study aims to determine public satisfaction and the level of performance of Buy The Service (BTS) Biskita Transpakuan Corridor 1 services using the Importance Performance Analysis method & the Customer Satisfaction Index method. The results showed that there are 4 (four) attributes that show consumers are satisfied and must be maintained. There are 6 rated ordinary and 7 (seven) attributes rated excessive. The CSI results show a value of 72.79% in the interval 0.51-0.65, meaning that in general Trans Pakuan bus consumers are in the satisfied category, so that Trans Pakuan's overall performance is considered good. Based on the Importance Satisfaction Analysis method, it shows that the aspects that need to be prioritized are the convenience of cleaning facilities at bus stops, waiting time, information on the arrival time of bus cars and information on disturbances.

Abstract

Cikidang Fishery Port is one of the ports with serious abrasion and sedimentation problems. Seawater abrasion significantly affects some coastal areas that lack breakwater protection. Seawater abrasion causes the shoreline to recede further into the land, thereby narrowing the operational area of the coast. Not only that, harbour areas that are both protected and unprotected by breakwater also experience problems regarding water areas caused by ocean currents, tides, and large waves that lead to sedimentation. Sediment reduces the depth of harbour dock waters, making it impossible for ships to dock. As a fishing port that contributes significantly to the local economy, the Cikidang Fishery Port (CFP) necessitates analysis and solutions to address the issues of sedimentation and abrasion. References for this study used both primary and secondary data. We used a GPS handheld to measure the coastal area, and we conducted comparative studies using satellite images to gather secondary data. This will calculate the effective duration of the dredging process, enabling precise execution and minimizing the associated expenses.

Abstract

Timor-Leste shares the island of Timor with Indonesia and is strategically located near Australia, giving it significant maritime potential for both domestic connectivity and international shipping logistics. To support maritime transportation and national economic growth, the Government of Timor-Leste, through the Ministry of Transport and Communications, plans to develop and upgrade several port facilities, including Beaco Port. Therefore, a jetty layout plan that meets technical planning standards and operational requirements is required. This study focuses on the planning and design of a jetty structure for vessels with a capacity of 1000 DWT. The planning process includes site selection, determination of quay type and dimensions, quay basin, navigation channel, turning basin, causeway dimensions, fender and bollard specifications, as well as the spacing between fenders and bollards. The analysis was conducted using several software packages, including Microsoft Excel, WR Plot, ODV (Ocean Data View), MIKE Zero, and AutoCAD. The results indicate that Site 2, located at coordinates 8°56'53.43” S and 126°28'2.08” E, was selected as the optimal location. The proposed design consists of a jetty-type quay with dimensions of 122.6 m in length and 32.5 m in width, a one-way navigation channel with a depth of 10 m, width of 46.4 m, and length of 200 m, a turning basin with a diameter of 201 m, and a jetty basin with a depth of 6 m, length of 100.5 m, and width of 20 m. The selected fender type is V-SAN 800H × 1000L with 10 m spacing between fenders and WF500 fender piles, while the bollard system uses TEE BOLLARD with a capacity of 100 kN and 15 m spacing between bollards.
