Judul: Dampak Dinamika Banjir Pasang (Rob) terhadap Sistem Sosial Ekologis Kota Semarang (Studi Kasus di Kelurahan Tanjung Mas)
Abstrak: Region of coastal area of Semarang represents the region with the solid activity complexity. The complexity activities caused the level of pressure at the region. Environmental damage have been seen. Phenomenon that happened until now is tidal floods called rob. If tidal floods handling install is not systematic, estimated Semarang will sink. The aims of this study was to identife social ecological system dynamics, to estimate ecological impact and economic social, to compile indication strategy of management of coastal area base on the adaptation to tidal floods.The result showed that pursuant to historical analysis shows that tidal floods increased in the case of height irrigate and also spread area affected, pond tidal flood resulted the change of structure of social condition and space of area economics affected, analyse the scenario that the development embank the sea (seawall) with the environmental management with of cultivation mangrove alongside embank and drainage basin in physical represent the effective solution in area management. Tidal floods gived magnitude effects not for human and all activities but for the region and ecological system.

Judul: Validation method for determination of apigenin in extract celery with high performance liquid chromatography
Abstrak: Apigenin is an active substance derived from celery (Apium graveolens) and widely used for the treatment of gout. Determination method of apigenin which have been validated was introduced by Frankee et al. J Food Compos Anal 17: 1-35 (2005). Apigenin analysis was done by high performance liquid chromatography (HPLC). To make sure that HPLC analysis method can be used for the intended purpose then the method was validated. Parameters determined on method validation were linearity, limit of detection, limit of quantification, precision, and accuracy. All parameters were in accordance with the acceptance criteria of Association of Official Analytical Chemist. The linearity in the concentration of 3,8; 5,7; and 7,6 mg/l had correlation coefficent of 0,9900–0,9998. limit of detection in this method was 2,7222 mg/l and limit of quantification was 8,2500 mg/l. Interday precision in five restating showed good precision with relative standard deviation of 3,85%. Accuracy was determined by standard addition method with recovery percentage of 95,00–118,77%. Average concentration of apigenin is 0,0052% (w/w).
