Abstrak: Fishing gear used by the fishermans of North Halmahera district to conduct fishing is very diverse, good for catching pelagic, demersal, and reef fish. The dominant fishing gear used by fishermen are fishing yield, multiple hand line, gill nets, etc., using a fleet of boats is simple until a boat or ship with a capacity of 10 gross tonnage. However, the use of destructive fishing gear, the environment still numerous in some areas of North Halmahera waters such as the use of bombs. The tool is dropped into the water contained a lot of fish, and causing an explosion that resulted in the death of small fish and large around the blast site. This action is performed not only in shallow waters sea, but also performed in deep waters sea. This action is very harmful to the environment and fishermen. The fish that have not been feasible arrested will die, and the risk of disability or until death can be experienced by the fishermans.

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
