AbstractIn term of energy utilization diversification, nuclear energy has become an optionin energy mix of 2025. Nuclear power plant site preparation is one of the primaryissues in the development of nuclear energy program. The area of study is locatedin Banten Province which is seismically active either related to faulting orvolcanic activity. Therefore, analysis of surface faulting which coveredidentification and characterization of capable faults were crucial to investigatefurther. Capable faults identification has been acquired through comprehensiveanalysis of SPOT-5 satellite imagery, geological field observation data andgeophysical data which include gravity, geoelectric and magnetotelluric data.Based on morfostructural analysis of satellite imagery and geological fieldobservation, it has been identified faults with characteristics and chronologynamely dextral strike-slip faults N1680E/860 indicating a reactivation into normalfaults N1780E/680; normal faults N3500 E/680; normal faults N2520E/700; andsinistral strike-slip faults N130-1400 E/720-820. The existence of these faults hasbeen confirmed using 2-dimensional gravity and resistivity model and inversion.Besides that, based on 2-dimensional magnetotelluric data inversion the presenceof Pre-Tertiary basement rock is indicated at depth of more than 700 meters. Interm of the rock ages, the identified faults were younger than Middle Pleistocene.Accordingly, all the identified faults were categorized as capable faults."

The aim of this research was to study the relationship between biological aspects length, weight and gonad maturity level of Indian Mackerel and physical sea surface temperature, transparency, and current velocity , chemical parameters salinity and chlorophyll a of the fishing grounds in Pandeglang regency. The research was conducted from December 2016 to April 2017. Samplings were taken at three sites within the fishing grounds in Batu Hideung, Sumur and Panaitan. The measurement of length, weight, and surgery for gonad maturity level observation as well as physical chemical waters parameters measurement were conducted in situ. The sea surface temperature at the study site ranged from 28.20 29.700C, current velocity 0.6 0.8 m s, transparency 6 9 m, and salinity 30 32 g l. While the value of chlorophyll a in December was 0.13 mg m3, at which the fishing ground conditions were less fertile, the chlorophyll a value in February April ranged from 0.9 to 2.0 mg m3, indicating that the fishing grounds within Batu Hideung and Sumur were in fertile condition. The fork length Indian mackerel caught by a bottom gillnet was about 14 22 cm mode 18.3cm. The length of fish at first capture Lc was 17.17 cm. The value of slope b in the length weight relationship revealed that male Indian mackerel was in negative allometric while female Indian mackerel was still positive. Length at first maturity Lm was 17.91 cm. The value of Lc is lower than Lm, revealed that the fishing activity has negative impacts on sustainability of Indian mackerel. Efforts including arrangement and supervision of fishing operations based on the spawning patterns are needed to manage Indian mackerel resources."

"ABSTRAKFisheries resources management aimed to improve community welfare especially fishermen and to conserve the fisheries resources and its environment, to keep the capture fisheries business system sustainability efficient and profitable. Beside marketing guarantee, optimalization between fisheries resources stock and fishing effort in each of fishing area. The improvement of capture fisheries must be held based on the existing condition, i.e.: marketing in determining the priority commodity, maximum sustainable yield and fisheries resources utilization level to determine limit of fisheries resources utilization chance, fishing technology and socio-economic condition to identify the fishermen's earns and absorption of labors related to capture fisheries sector. Based on the marketing aspect analysis, it is determined that the kinds of priority commodity in Southern of West Java Province are lobster, shrimp, tuna, skip jack tuna, and layar. Hence, the potency (MSY) and fisheries resources utilization level of the priority commodity still has very large chance to improve, except lobster has large enough chance.
