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

Spons merupakan organisme simbion yang memiliki peran penting dalam ekosistem pesisir, seperti menyaring air, menguraikan bahan organik menjadi nutrien, menyediakan tempat berlindung bagi mikroorganisme, serta berperan dalam stabilitas dan pengikatan sedimen. Penelitian ini bertujuan untuk mengidentifikasi komposisi, keanekaragaman spesies spons yang terdapat di habitat lamun di Pulau Panggang, Kepulauan Seribu, DKI Jakarta. Penelitian dilakukan di tiga lokasi menggunakan transek garis sepanjang 50 dan 11 transek kuadrat berukuran 0,5 x 0,5 meter di setiap garis transek. Sampel spons diambil dengan memotong sebagian kecil dari setiap spons untuk dianalisis spikulanya. Hasil penelitian menunjukkan bahwa spons yang ditemukan di seluruh lokasi penelitian terdata sebanyak 10 spesies dan didominasi oleh Chondrilla caribensis forma dengan nilai kerapatan spons sebesar 0-13 ind/m². Indeks keanekaragaman spons di Pulau Panggang berada pada kategori sedang yang menunjukkan bahwa distribusi genus dalam kumpulan spons di Pulau Panggang cukup merata. Kandungan fosfat dan kecepatan arus menunjukkan korelasi yang kuat dan positif terhadap kepadatan spons, sementara suhu memiliki korelasi positif terhadap kerapatan lamun. Di sisi lain, korelasi antara kepadatan spons dan kerapatan lamun relatif lemah, yang mendukung temuan bahwa kedua komponen ini tidak memiliki keterkaitan erat dalam ekosistem yang diamati.

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.
