Judul: Strategi Adaptasi Nelayan Pelabuhanratu terhadap Perubahan Iklim
Abstrak: The impact of climate change can be seen in the phenomenon of rising sea levels, changes in sea surface temperature, sea water salinity and weather patterns, as well as changes in rainfall and hydrological patterns. Fishermen in Pelabuhanratu perceive the climate change impacts as the frequent storms, a sudden weather changes, and reduce of catches. Consequently, it will reduce the household income from fishery activity. To cope with the impact of climate change, fisher communityin Pelabuhanratuperforms adaptation strategiesin various ways, such as: diversification, intensification, mobilization of household members, social relations, and sell and pawn valuables. The types of adaptation strategies perform by the fisher community in Pelabuhanratu are different according to social classes they belong to, as each social class owns different social characteristics. In Pelabuhanratu, fisher communitybelongs to three social classes: modern equip fisher, traditional equip fisher, and none equip fisher or labor.

Judul: Strategi adaptasi Nelayan di pulau-pulau kecil terhadap dampak perubahan iklim (Kasus: Desa Pulau Panjang, Kecamatan Subi, Kabupaten Natuna, Kep. Riau)
Abstrak: Penelitian ini bertujuan menganalisis pengaruh perubahan iklim terhadap kondisi sosial-ekonomi nelayan, serta mengidentifikasi strategi adaptasi dan mitigasi yang dilakukan nelayan dalam menghadapi dampak perubahan perubahan iklim. Metode dalam penelitian ini menggunakan metode kuantitatif dan kualitatif. Hasil penelitian menunjukan bahwa terjadinya perubahan iklim berpengaruh pada aspek sosial-ekonomi nelayan. Pengaruh pada aspek sosial-ekonomi tersebut yaitu kalender musim yang tidak tentu, hilangnya beberapa hewan yang menjadi penanda penentuan musim, dan peningkatan intensitas badai di laut yang mengganggu aktifitas penangkapan nelayan. Oleh karena itu, strategi yang tepat guna mentransformasikan nelayan dalam rangka menyesuaikan diri dengan laju perubahan iklim sangat diperlukan. Bentuk strategi adaptasi yang dilakukan dibedakan menjadi beberapa bentuk, yakni: melakukan diversifikasi kegiatan ekonomi; investasi pada teknologi penangkapan; menjalin hubungan baik dan kerjasama dengan nelayan lain; dan melakukan migrasi melalui pencarian daerah tangkapan baru; memanfaatkan hubungan sosial serta memobilisasi anggota keluarga.

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).
