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. The sedimentation rate in PPP Tegalsari within the research period of 15 days, namely in existing conditions ranging from 1.095 mm/year, in alternative 1 ranging from 0.438 mm / year and in alternative 2 ranging from 0.486667 mm/year. In the results of the research conducted that the level of sedimentation conditions in Tegalsari PPP is low. Thus, at the time of sedimentation does not affect the shipping channel at PPP Tegalsari.

Abstract

Corals grow annually at varying rates, influenced by environmental conditions. As key indicators of marine ecosystem health, studying coral growth is essential for predicting the impacts of environmental change. While previous research has explored coral growth extensively, most studies focus on existing conditions and the descriptive influence of environmental parameters. In fact, coral growth time-series data offer potential for deeper analysis, particularly in identifying dominant periodicities and enabling long-term projections. This study aims to develop an annual coral growth model using fuzzy logic approach. The Indian Ocean Dipole (IOD) is identified as a significant factor influencing the growth of Porites lutea in Tunda Island. Variations in sea surface temperature during IOD events notably affect coral growth, with positive IOD phases (IOD+) generally enhancing it. Analysis shows that the annual growth rings of Porites lutea in the northern station of Tunda Island, which borders open waters respond more slowly to SST fluctuations compared to the southern station, which is more sheltered. Fuzzy simulation results suggest that corals may be able to adapt to climate change. By the year 2085, coral growth is projected to recover from -0.75 cm to 0.1 cm by 2100. Based on SST projections from 1900 to 2100, SST anomalies are expected to continue increasing, reaching +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.
