This research was conducted from January 2023 to April 2023. The results showed that the extracts o…
Research on the design characteristics of small scale fisheries vessels was conducted in Sungsang Village, Banyuasin Regency, South Sumatra Province, December 2022 – January 2023. The research method used was the survey method, taking direct measurements of the main dimensions of the dominant fishing vessels namely motor boats (pompong) and outboard motor boats (Jol). Processing of ship desig…
Through the length of Batanghari River, there are many community activities, such as fishing, coal-carrying, and industrial activities. These various activities can cause pollution of the aquatic environment, such as pollution of heavy metals Pb and Cu. This pollution can be overcome by using phytoremediation techniques using Avicennia alba Blume. which grows in Mangrove Forest Nature Reserve E…
Pertambangan batubara di Indonesia banyak dilakukan secara terbuka(surface mining). Penambangan batubara yang dilakukan secara terbuka akanmelepaskan asam sulfat dan mendorong terjadinya oksidasi mineral sulfida.Proses ini selanjutnya akan menghasilkan limbah berupa air asam tambang (AAT) dan mengakibatkan tingginya akumulasi logam berat pada tanah dan air. Air asamtambang (AAT) memiliki nilai …

Microplastics are particles of 1-5000 µm composed of synthetic polymer materials. Various activities (sanitation, traffic emissions, industry, agriculture, fisheries) are a source of microplastics. The microplastics are transported to the waters through runoff, the river flows, and even drift in the air (atmospheric microplastics). These microplastics are solid particles with a variety of comp…
Kualitas hidup pada individu dipengaruhi oleh berbagai faktor, salah satu diantaranya adalah munculnya gangguan makan. Night Eating Syndrome (NES) sebagai gangguan makan yang dipengaruhi oleh tingkat stress ditandai dengan mengonsumsi makanan secara berlebihan pada malam hari dapat terjadi pada berbagai individu di berbagai kelompok usia, termasuk mahasiswa akhir. Mahasiswa akhir memiliki kewaj…
Density is an essential factor impacting glass eel A. bicolor cultivation production. The increase in glass eel density causes competition in getting oxygen, feeds, and space movement, affecting the glass eel's physiological condition. This research aimed to determine the effect of different densities on glass eel A. bicolor production cultured in swamp water media. The study was conducted at t…
Polyculture ponds (shrimp and milkfish) in Gilirang Village, Muara Sugihan District, have experienced a decline in pond yields from year to year. Pond water quality is thought to be one of the important factors in the successful productivity of polyculture ponds. Decreasing water quality will have an impact on cultivators who can experience stress and even death. The purpose of this study was t…
Tanjung Api-api Port is a water area that is strongly influenced by tides, currents, ports and agriculture resulting in changes in sedimentation and changes in coastlines both abrasion and accretion around the coast. The purpose of this study is to analyze the sedimentation rate at Tanjung Api-api Port, analyze changes in coastline in Tanjung Api-api Port, and analyzed the dynamics of coastline…
The Satellite Derived Bathymetry (SDB) method can collect bathymetry data in shallow waters based on satellite imagery. The bathymetry data obtained from this methos can be used to fill in the gaps in data collected from hydrographic surveys. The purpose of this research is to evaluate the use of two algorithms in obtaining information on the depth of shallow waters in Karimunjawa waters. The a…
Nipah is a species of mangrove palm that lives on the back of the mangrove zone. Nipah has morphological adaptations that can be seen on leaf organs at a certain levels of salinity. Research on morphological adaptation of Nipah in Banyuasin regency, South Sumatra is still limited, so it is necessary to do research on the form of morphological adaptation in Nipah with different levels of salinit…
The Banyuasin waters have abundant fisheries resources supported by adequate ecosystems condition. The dynamic ecosystem affects biota such as fish to tend to aggregate to help them survive from predation or feeding. This study was conducted to identify fish shoals using hydroacoustic methods and then determine the relationship between acoustic descriptor variables and environmental parameter a…
High concentration of Total Suspended Solid (TSS) can increase turbidity and obstruct light penetration to the water column. The distribution of TSS can be observed using satellite imagery by transforming algorithms that can convert pixel values into estimated TSS concentration values. The objective of this study is to examine the comparison of TSS concentration distribution patterns in Sentine…
The Palembang is one of the most floodful cities,the problems of the Palembang are serious enough for the government,there is a considerable amount of marshes and also the musi river,which if the rainly season comes the musi river will overflow.Other factors include slopes,elevation,soil,types,land use,and river density. In the study the method used is the suspend method,in which any parameters…
Coral reef ecosystems provide a variety of habitats for marine biota such as coral reef fish, thus making them one of the most diverse marine ecosystems. This study aims to analyze the condition of coral reefs (percentage cover), coral reef fish abundance, and the relationship between Acropora and non-Acropora coral types and the abundance of coral reef fish in Kelapa Dua water, Seribu Island. …
The vegetation that dominates Payung Island is the mangrove forest, because it is located at the mouth of the Musi River, where fresh water and sea water meet, so the surrounding salinity is quite high, where the mangrove forest is still well preserved. At the Payung Island location there are several types of mangroves including R.apiculata, Avicenia alba, A.marina, A.officinalis and K.candel, …
