Abstract

Coral reefs found in Tihik-Tihik village shows moderate coral reef status with indications of greater potential for damage so that protection efforts are needed. This research aims to analyze the abundance and community structure of plankton in reef ecosystems natural and artificial reefs. Sampling was carried out in the month of October – November 2020 at four stations at high and low tide with using a plankton net, then identified in the Water Quality Laboratory FPIK Unmul. The identified plankton consisted of 7 classes, namely, Bacillariophyceae (21 species), Conjugatophyceae (3 species), Copepoda (8 species), Cyanophyceae (1 species), Dinophyceae (10 species), Oligotrichea (3 species), Trebouxiophyceae (1 species). The highest total abundance of artificial reef ecosystems was at station 2 pairs with a total of 6741 ind/l. The diversity index (H') ranged from 2.12 to 2.22. The uniformity index (E) ranged from 0.92 – 0.96. The dominance index (D) ranges from 0.11 to 0.13. Sorenssen similarity index ranged from 29 – 68%.

Abstract

Samboja Kuala is one of the Kelurahan in Samboja District which is an area where most of the population works as fishermen.  There are two types of fishery activities in the Samboja Kuala area, namely capture fisheries (fishermen) and aquaculture fisheries. One of the most common catches obtained by fishermen is shrimp.  Yellow-spotted shrimp (Metapenaeus monoceros) is one of the catches of fishermen shrimp in Samboja Kuala Waters.  This study aims to determine several parameters of population dynamics using the carapace length data frequency method.  The research was conducted in Samboja Kuala waters, Kutai Kartanegara Regency, in November-December 2022.  Based on the results of the study, the sex ratio between males and females was 0,38: 2,65.  The length range in male and female sex is 48,34 mm – 78,85 mm and 48,80 mm – 90,78 mm.  And the natural mortality (M) of males and females was 1,27 per year and 1,65 per year, the capture mortality (F) of males and females was 0,63 per year and 1,64 per year, the total mortality of males and females was 1,90 per year and 3,29 per year, and the exploitation rates of males and females were 0,33 and 0,50.  New additions of males occurred in October by 16,27% and new additions of females occurred in October by 24,93%.  And it is known that the yield per recruitment value is 0.04 grams / recruitment.

Abstract

Tiger prawn (Penaeus monodon) is a type of shrimp from the Penaeidea family and is one of the caught in Samboja waters. This research was conducted in November-December 2022 in Samboja Kuala Waters, Kutai Kartanegara by catching shrimp at night using trawl fishing gear. The sample used was 100 tiger prawns (Penaeus monodon) with 42 females and 58 males. This study aims to determine the morphometric characters of tiger shrimp (Penaeus monodon) and to analyze the morphometric measurements. In the analysis using Ancova, the results obtained were 12 morphometric characters of tiger shrimp (Penaeus monodon) with significant values greater than 0.05, namely RST, PK, PRT, PRN, PT, PP, PKB, PTB, PNB, PE and PTK . So based on the initial hypothesis, if the significant number is greater than 0.05 Ho, it is accepted, which means that there is no relationship between the morphometrics of male and female tiger shrimp (Penaeus monodon).

Abstract

Perairan sekitar Pulau Miang memiliki aktivitas yang cukup tunggi, salah satunya aktivitas industri kelapa sawit yang mana limbah pembuangannya bisa langsung masuk ke dalam perairan tersebut. Kegiatan wisata dan masyarakat Pulau Miang Besar banyak yang langsung berhubungan dengan perairan. Kegiatan seperti pelayaran, penangkapan ikan dan pembuangan limbah secara langsung ke dalam perairan mempengaruhi kondisi kualitas perairan tersebut. Tujuan penelitian ini adalah menentukan status mutu air laut pada perairan Pulau Miang Besar dan untuk mengetahui atau menduga kondisi pencemaran yang ada pada perairan. Pengambilan sampel dilakukan pada saat pasang dan surut sebanyak 5 stasiun penelitian yang tersebar mengelilingi Pulau Miang Besar. Penentuan status mutu air laut menggunakan metode Indeks Pencemaran mengacu pada Keputusan Menteri Lingkungan Hidup Nomor 115 Tahun 2003. Parameter yang diamati terdiri dari parameter fisika dan kimia antara lain: suhu, salinitas, TSS, oksigen terlarut, pH, fosfat, dan nitrat. Hasil analisis yang didapatkan kemudian dibandingkan dengan baku mutu yang ditetapkan dalam Peraturan Pemerintah Nomor 22 Tahun 2021. Status mutu air laut di perairan Pulau Miang Besar menunjukan bahwa tingkat pencemaran pada setiap stasiun termasuk dalam tercemar ringan saat pasang maupun surut. Parameter yang berpengaruh terhadap tingkat pencemaran perairan Pulau Miang adalah TSS, fosfat dan nitrat.

Abstract

Kualitas air merupakan salah satu faktor yang dapat memberikan dampak terhadap ekosistem terumbu karang. Penelitian ini bertujuan untuk mengetahui kondisi kualitas air dan parameter yang berpengaruh terhadap indeks pencemaran pada perairan ekosistem terumbu karang di dalam dan di luar Kawasan Konservasi Kota Bontang. Penelitian ini dilaksanakan pada bulan Desember 2024 hingga Januari 2025. Sampel air diambil pada 4 (empat) stasiun, metode pengukuran parameter kualitas air in situ dan laboratorium. Analisis data secara deskriptif untuk mengetahui kondisi kualitas air dan parameter yang berpengaruh terhadap indeks pencemaran. Hasil penelitian menunjukkan kondisi kualitas air bervariasi, indeks pencemaran umumnya menunjukkan kategori kondisi baik hingga tercemar ringan. Perbandingan kualitas air menunjukkan bahwa kondisi di luar kawasan konservasi cenderung lebih baik daripada di dalam kawasan konservasi.

Abstract

Coastal and marine areas have ecological and economic potential for development and utilization across multiple sectors, including mining. However, the interaction between coastal management and coal mining operations often leads to adverse ecological consequences and socio-environmental conflicts that threaten sustainability. To address these challenges, integrated approaches are required to promote synergy between coastal management and coal mining practices. This review adopts an exploratory approach through comprehensive literature analysis, with data drawn from reputable scientific databases, including Scopus, Web of Science, MDPI, and PubMed. The selected studies were systematically identified and analyzed using qualitative descriptive techniques. Achieving sustainable management in both coastal and coal mining sectors requires a holistic perspective that incorporates sociocultural, economic, environmental, and governance dimensions. Environmentally friendly technologies, rehabilitation of degraded coastal and post-mining ecosystems, and empowerment of local communities are among the alternative strategies that can be implemented to align both sectors toward shared economic goals. Economic benefits can be enhanced by optimizing the collaborative potential of the coastal and coal mining sectors, particularly through the establishment of green employment opportunities, the development of ecotourism, and the sustainable utilization of natural resources. The realization of sustainable coastal and coal mining management relies on synergistic cooperation among mining companies, governmental bodies, academia, stakeholders, and local communities to promote a sustainable economy
