Sempu Island is a nature reserve that has fringing reef with percentage of living coral cover almost constant 37% from 2009 to 2016. Coral massive Porites lutea in this area has a growth rate about 1.09 cm/yr. in average and almost similar with others. Coral massive growth rate can be monitor through their skeletal annual banding. They have two type annual banding, low density for slow growth coral skeletal and high density for fast growth rate of coral skeletal. In this banding coral can record any environmental condition such as sea water temperature, tides and heavy metal. The aim of this research was to know the concentration of copper in Sempu Island Nature Reserve in the past used ICP-OES. The result showed that the Cu concentration in P. lutea skeletal band from 2009-2016 were: 5.213; 6.403; 5.825; 6.511; 6.132; 6.403; 6.467; 6.22 mg/kg. The coral skeletal can absorb the pollutant for hundred years, and it will give important information for palaeo environment that can used for climate modelling in the future.

Coral reef is a massive natural building block that mainly composed of hard coral. In ecological view coral reef is the center of biological activity for shelter, foraging and feeding place. Porites lutea is a common coral in reef flat area such as in Pantai Kondang Merak. This coral can form a massive with hillocky colony surface and has a slow linear extension rate, that made this coral has long longevity. The annual growth band of coral skeleton provide information of pollutants in the coastal extending back over several years ago due to ability of coral aragonite traped trace metal from environment. The aim of this research was to determine the concentration of trace metals of Cd, Cu and As along with the coral annual banding. The heavy metals detection was performed using ICP-OES (iCAP 7400 Series). The concentration of Cd, Cu and As in sample 1 (KM1) were 2.236 mg/kg, 9.726 mg/kg, and 2.474 mg/kg, while sample 2 (KM2) were 1.989 mg/kg, 19.157 mg/kg, and 2,064 mg/kg respectively. Two ways mechanism of trace metals to be trapped in the coral skeleton are by direct mechanism when trace metals in a form dissolved ion that were uptaken by coral then stored into coral skeleton and by indirect mechanism when particulate metals ingested by plankton then eaten by coral through coral tissue. The tracing of heavy metal in coral is provided important information of environment condition of the sea from 2009 - 2015 that may be used for authority decision regarding pollutant ambient in the sea environment.

One of the leading commodities in the North Coast of East Java which has a large production is gulamah (Sciaenidae). This fish is one of the marine fisheries commodities that have high potential. Previously the use of gulamah was limited to fresh fish and dried fish. Lately these organs in fish (swimming bladders) have also been widely used and actually have much higher economic value. The high economic value of these commodities has implications for the increasing pressure on exploitation of these fish. In fact, sometimes arrests are made without regard to responsible fishing rules. Gulamah is one type of fish that often makes a â€œcroakâ€ sound in its behavioral activities. Study of the schooling sound spectrum of gulamah (Sciaenidae) as a preliminary study for the manufacture of effective and environmentally friendly Sound-Fish Aggreagating Device as one of the food security instruments for marine fisheries products. So it isexpected that with the introduction of new technologies that are efficient, effective, simple and can provide economic added value for fishermen. Analytical descriptive research method and experimental fishing, the data collected is the sound spectrum data schooling gulamah (Sciaenidae), where data collection is carried out at Tombokboyo Waters, Tuban, East Java. The results showed that gulamah in Tombokboyo waters issued a sound with an average amplitude of around -54,97 dB, an average frequency of 732,129 Hz, with a sound duration of 130 miliseconds

DEVELOPMENT OF UNDER WATER LAMP AS A TOOL TO LIFT NET IN TAMBAK LEKOK VILLAGE PASURUANBagan is one type of fishing gear that uses light to collect fish. The lights are expected to stimulate the fish to come and stay around the light and than arrested with net. The use of light for fishing is growing rapidly, almost all fishing gear to use light as a tool for collecting fish. Application of this technology aims to increase fish catch fishermen in District Lekok through the application of technology underwater lamp with LED. Underwater lamp applied to the bagan tancap with a certain intensity and color to find the intensity of light and color that give the best catches. Best catches in the light of 450 lux is capable of delivering the highest total catch of 254 kg, it is supported by the values of illumination of 1.5 lux at a distance of 5 m. Types of fish that were caught on as much as 23 step chart types where the type of Stolephorus spp, Selaroides spp, Leiognathus spp, Loligo sp, Rastrelliger spp is a type of fish that always caught each fishing operation. Keywords: auxilary, development, lamp, Lekok, lift net ABSTRAK Bagan merupakan salah satu jenis alat tangkap yang menggunakan lampu sebagai alat bantu pengunpul ikan. Cahaya lampu diharapkan dapat merangsang ikan untuk datang dan berkumpul disekitar sumber cahaya sampai pada suatu catchable area tertentu, lalu penangkapan dilakukan dengan alat jaring maupun pancing. Penggunaan lampu untuk penangkapan ikan saat ini berkembang pesat, hampir semua alat tangkap menggunakan lampu sebagai alat bantu pengumpul ikan. Aplikasi teknologi ini bertujuan untuk meningkatkan hasil tangkapan ikan nelayan bagan tancap di Kecamatan Lekok melalui penerapan teknologi lampu celup bawah air berbasis lampu LED. Lampu celup bawah air diterapkan pada bagan tancap dengan intensitas dan warna tertentu untuk mencari intensitas cahaya dan warna yang memberikan hasil tangkapan yang terbaik. Hasil tangkapan ikan yang terbanyak adalah pada lampu 450 lux yang mampu memberikan total tangkapan terbanyak 254 kg, hal ini didukung dengan nilai nilai illuminasi sebesar 1,5 lux pada jarak 5 m. Jenis ikan yang tertangkap pada bagan tancap sebanyak 23 jenis dimana jenis ikan teri (Stolephorus spp), ikan selar (Selaroides spp), ikan pepetek (Leiognathus spp ), cumi – cumi (Loligo sp), ikan kembung (Rastrelliger spp) merupakan jenis ikan yang selalu tertangkap disetiap operasi penangkapan.

Kondang Merak was lied on south of Java sea that has monitored coral reef inside. Environment condition such as load of terrestrial’s nutrient into the sea, increase of surface water temperature and tourism activities were affected on coral reef health. The massive Porites that common coral found in this location need be monitored gradually to see coral condition over time. The research was conducted on May 2015 in reef flat area of Kondang Merak. The aims of the research were to know distribution of massive Porites and oceanography condition in Kondang Merak. The highest sea surface temperature was 26,46o C in transect number 2 at station 1 (eastern part). Salinity of sea water was in normal range between 34, 42o/oo to 35,75o/oo, dissolved oxygen was on range 6 mg/l sampai 9,1 mg/l and pH was 7,23 sampai 8,68 respectively. Two species on massive Porites they were Porites lobata dan P. lutea. In station 1 the average diameter of P. lobata was 228.57 cm and P. lutea 63.89 cm, in while P. lobata in station 2 was 260.57 cm and P. lutea 153.56 cm.
