Manusia memasuki suatu sistem ekologi tertentu tidaklah semata-mata hanya sebagai suatu organisme yang mempunyai hubungan fisik dengan organisme yang lain, tetapi ia juga membawa kebudayaan, suatu fak- tor yang mempengaruhi dan dipengaruhi oleh seluruh total. jaringan kehidupan (Steward, 1955; dalam Rappaport, 1971).. Adanya kebudayaan ini memungkinkan manusia memiliki lenturan ekologis yang lebih tinggi dibandingkan dengan. organisme lainnya. Sebagai akibat faktor keturunan kendala-kendala biologis dalam memperoleh dan dan memproses bahan makanan, suatu organisme tertentu hanya dapat ber- peran pada satu atau beberapa ekosistem saja. dst ...

This research has been conducted with direct observation in the field and interviews with 30 persons in every village. The result from observation of ecological mangrove condition show that typology of mangrove in both area are dominated by Avicennia marina with good condition, mangrove density range is about 1067-1178 ind/ha and 1622-2000 ind/ha in accordance with the Decree of the State Minister for the Environment No. 201 Year 2004. Analysis of Principal Component Analysis (PCA) results that the social factors affecting the conservation in Kartika Jaya villages are community participation in mangrove planting, knowledge about the function of mangrove ecosystems, the distance to the ecosystem, and type of job.

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).
