Biofouling is an organism that sticks to submerged substrates in aquatic ecosystems such as docks and ship hulls that are microfouling or macrofouling. The purpose of this study was to determine the effect of the addition of Nypa fruticans leaf extract to paint as a natural antifouling on the inhibition of macrofouling attachment. This study used a randomized group factorial design (RAKF) using…
This study aims to determine the leaf anatomical structure of several plants belonging to the Lamiaceae family including basil (Ocimum sanctum L.), lavender (Lavandula angustifolia Mill.), sungkai (Peronema canescens Jack.), red salvia (Salvia splendens Sellow ex Roem. & Schult.), buakchao grass (Anisomeles indica (L.) Kuntze), undel-undel grass (Hyptis rhomboidea Mart & Gal.), pagoda flower (C…
The Aedes aegypti L mosquito is currently one of the vectors of the disease that is now being targeted by researchers to find ways to control it without damaging the environment. This is because the Aedes aegypti L mosquito is the main vector of transmission of the Dengue Fever virus, which is a dangerous disease. Generally, the eradication of Aedes aegypti L uses synthetic insecticides because…

TEST ANTIFOULING ACTIVITY OF Avicennia marina (API-API) FRACTION AS A NATURAL ANTIFOULING ON MACROFOULING AT SUNGSANG WHARF Ulil Sarifatul Aliyah NIM.08041281722022 SUMMARY Biofouling organisms generally cause problems that are detrimental to shipping transportation, such as damage to ship hulls, destroying structured substrates, blocking sewage lines. This problem can be overcome by using anti…
Coastal areas have very broad benefits both in the ecological and socio-economic. However, due to excessive use it can also have an impact on pollution in coastal areas. Heavy metal is a pollutant that is dangerous because it has toxic to the environment if its concentration exceeds the threshold. Payung Island is a lowland area that is overgrown by mangroves. This island is in the middle betwe…
The coastal areas have very promising potential, this is because coastal areas are the natural habitat of many individuals in nature. This potential is disrupted in the form of pollution, pollutants originating from agricultural industrial activities in the upstream river in the form of zinc (Zn) and those from lead (Pb) transportation activities around the coastal area is one of the causes of …
Infectious diseases are the main cause of high mortality and disease rates in developing countries such as Indonesia and can be caused by bacteria such as Staphylococcus aureus and Escherichia coli. Antibacterial is often used in medicine, but continuous use can cause bacteria to become resistant to antibacterials, so it is necessary to look for new antibacterial alternatives. Acacia plant (Aca…
Free radical molecules that people face in their daily activities require humans to get additional antioxidants from the outside. To overcome this problem, it is necessary to look for many sources of natural antioxidants considering the need for antioxidants that are increasingly needed and for seeing that there are negative effects that caused by using sintetic antioxidants excessively. Indone…
The main problem that often occurs in the shipping and fisheries industry is biofouling. Biofouling is the attachment and growth of adhering organisms to a substrate below the surface of the water. General measures used to control biofouling are still using antifouling paint made from tributyltin (TBT) which can be dangerous because it causes environmental pollution and also imposes on gastropo…
