Judul: Adaptation Strategy for Coastal Communitied in Facing the Impact of Climate Change (Case: Pari Island, South Seribu Islands, DKI Jakarta)
Abstrak: Perubahan iklim merupakan fenomena lingkungan yang terjadi akibat aktivitas manusia yang menyebabkan perubahan komposisi atmosfer secara global dan berupa variabilitas iklim yang teramati pada kurun waktu yang dapat dibandingkan. Perubahan iklim memberikan dampak lingkungan, sosial, dan ekonomi bagi masyarakat pesisir. Penelitian ini menggunakan pendekatan kualitatif dan kuantitatif. Pendekatan kualitatif dilakukan dengan menggunakan metode observasi dan wawancara mendalam terhadap informan serta pendekatan kuantitatif melalui metode survei dengan kuesioner kepada 50 responden dengan teknik purposive random sampling. Penelitian ini menggunakan uji rank spearman dan chi-square. Hasil penelitian menunjukkan (1) perubahan iklim menyebabkan terjadinya perubahan musim angin, kondisi ikan, coral bleaching, abrasi pantai, dan banjir rob (2) pendapatan masyarakat pesisir berkurang dan menyebabkan rumah tangga harus berbagi peran serta meningkatnya persaingan penangkapan ikan pada kalangan nelayan dan (3) karakteristik masyarakat pesisir memiliki hubungan yang signifikan dengan strategi adaptasi yang dilakukan rumah tangga pesisir., Climate change is an environmental phenomenon that occurs as a result of human activity, which causes changes in the composition of the atmosphere globally and in the form of climate variability observed over comparable time periods. Climate change has environmental, social, and economic impacts on coastal communities. This research uses qualitative and quantitative approaches. A qualitative approach was carried out using observation methods and in-depth interviews with informants, as well as a quantitative approach using a survey method with questionnaire to 50 respondents using a purposive random sampling technique. This research uses the Spearman rank test and chi-square. The results of the research show that (1) climate change causes changes in wind seasons, fish conditions, coral bleaching, coastal erosion, and tidal floods. (2) the income of coastal communities decreases and causes households to have to share roles, as well as increased fishing competition among fishermen; and (3) the characteristics of coastal communities have a significant relationship with the adaptation strategies carried out by coastal households.

Judul: Analysis the Level of Vulnerability of Fishermen Households in Response to Climate Change: Case of Pari Island, South Seribu Islands, DKI Jakarta.
Abstrak: Perubahan iklim mengakibatkan terjadinya peningkatan intensitas dan frekuensi cuaca ekstrim, perubahan pola hujan, pengingkatan suhu air laut, dan terjadinya kekacauan musim angin. Dampak tersebut kemudian berpengaruh terhadap tingkat kerentanan rumah tangga nelayan. Penelitian ini menggunakan pendekatan kualitatif dan kuantitatif. Pendekatan kualitatif dilakukan dengan observasi dan wawancara mendalam kepada 4 orang informan sedangkan pendekatan kuantitatif dilakukan dengan menggunakan kuesioner kepada 50 responden dengan teknik snowball. Teknik pengolahan dan analisis data dilakukan menggunakan microsoft excel 2019 dan rumus perhitungan LVI-IPCC. Hasil penelitian menunjukkan bahwa nilai keterpaparan pada RT01 sebesar 0,49 dan RT04 sebesar 0,57. Selanjutnya, nilai kapasitas adaptif RT01 sebesar 0,59 dan RT04 sebesar 0,55. Sementara itu, nilai sensitivitas pada RT01 sebesar 0,40 dan RT04 sebesar 0,42. Nilai komponen tersebut kemudian menghasilkan nilai indeks kerentanan rumah tangga nelayan dimana indeks kerentanan RT04 lebih tinggi dibandingkan RT01 dengan nilai -0,04 pada RT01 dan 0,09 pada RT04. Kata kunci: kerentanan, perubahan iklim, rumah tangga nelayan, Climate change has resulted in an increase in the intensity and frequency of extreme weather, changes in rainfall patterns, increased sea temperatures, and chaotic wind seasons. These impacts then affect the level of vulnerability of fishing households. This research uses qualitative and quantitative approaches. The qualitative approach was conducted through observation and in-depth interviews with 4 informants, while the quantitative approach was conducted using a questionnaire to 50 respondents using the snowball technique. Data processing and analysis techniques were carried out using Microsoft Excel 2019 and the LVI-IPCC calculation formula. The results showed that the exposure value at RT01 was 0.49 and RT04 was 0.57. Furthermore, the adaptive capacity value of RT01 was 0.59 and RT04 was 0.55. Meanwhile, the sensitivity value at RT01 was 0.40 and RT04 was 0.42. The component values then produced the value of the vulnerability index of fishing households where the vulnerability index of RT04 was higher than RT01 with a value of -0.04 in RT01 and 0.09 in RT04.

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).
