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

Fitoplankton sebagai organisme autotrof berperan sebagai produsen primer dan kerap digunakan untuk mengukur kesuburan suatu perairan. Perairan Palabuhanratu yang memiliki sumberdaya perikanan memiliki sejumlah aktivitas manusia di sekitarnya. Penelitian ini bertujuan untuk mengetahui struktur komunitas di Perairan Palabuhanratu. Sampel fitoplankton diambil pada Oktober 2022 dari empat stasiun, parameter fisika dan kimia air yang diambil antara lain suhu, salinitas, pH, dan DO. Terdapat enam kelas dan 27 genus fitoplankton yang ditemukan antara lain Dinophyceae, Bacillariophyceae, Oligotrichea, Chlorophyceae, Polycystina, dan Trebouxiophyceae dengan kelas yang dominan yaitu Bacillariophyceae. Kelimpahan fitoplankton tergolong rendah dengan kisaran 66–695 ind/l. Indeks keanekaragaman tergolong sedang dengan nilai 1,552–2,234. Parameter perairan menunjukkan bahwa kondisi masih mendukung pertumbuhan fitoplankton.

Abstract

The Department of Marine Science and Technology (MST) has a physics laboratory (dry and wet) and a field laboratory. Laboratory activities cannot be separated from potential hazards that can cause the risk of work accidents due to tools, materials, and the work environment. The establishment of a culture of health, safety, and the environment (HSE) and the application of a procedure for identifying possible risks and hazards, known as job safety analysis (JSA), are two strategies used to prevent and lessen work accidents in physics and field laboratories. Determining the efficacy of introducing HSE culture in the lab was the aim of this investigation. Analytical and observational cross-sectional methods were employed in quantitative research procedures. The variables used to evaluate whether the HSE culture has been applied are knowledge of HSE, the application of HSE, and comprehension of PPE. The results of observations showed that the application of HSE was reasonably efficient as a guide for safe and healthy activities; nevertheless, it still requires assistance and the fulfillment of many work processes in the laboratory.

Abstract

Sponges are symbiotic organisms that play a significant role in coastal ecosystems, such as filtering water, decomposing organic material into nutrients, providing shelter for microorganisms, and contributing to sediment stability and binding. This study aims to identify the composition and species diversity of sponges found in seagrass habitats on Panggang Island, Thousand Islands, DKI Jakarta. The research was conducted at three locations using a 50-meter line transect and 11 square transects measuring 0.5 x 0.5 meters along each line. Sponge samples were collected by cutting small pieces from each sponge for spicule analysis. The results indicate that a total of 10 sponge species were recorded across all research locations, dominated by Chondrilla caribensis forma, with sponge density values ranging from 0 to 13 individuals/m². The sponge diversity index on Panggang Island falls within the moderate category, indicating that the distribution of genera within the sponge community is relatively even. Phosphate concentration and current velocity showed a strong positive correlation with sponge density, while temperature exhibited a positive correlation with seagrass density. Conversely, the correlation between sponge density and seagrass density was relatively weak, supporting the findings that these two components do not have a close relationship within the observed ecosystem.
