Judul: Estimasi Nilai Kerugian Ekonomi dan Strategi Adaptasi Terhadap Banjir Rob di Kampung Pondok, Pesisir Desa Pantai Harapan Jaya, Kecamatan Muara Gembong, Kabupaten Bekasi
Abstrak: Muara Gembong Sub-district is one of the northern coast Java located in Bekasi District. Muara Gembong Sub-district surrounded by the Java Sea and crossed by the Citarum river with four tributaries which end to the Java Sea. Pantai Harapan Jaya Village is the widest coastal region at Muara Gembong Sub-district which often experienced frequent tidal flood. Kampung Pondok is the worst affected area in the Pantai Harapan Jaya Village which are directly affected by tidal flood. People who live in Kampung Pondok experienced economic losses because of tidal flood. The purpose of this research were to identify perception community about the characteristics and impacts of tidal flood, to estimate economic losses by tidal flood, to identify factors that affected community’s decision to make preventive measures and to identify the adaptation strategies to minimize the impact of tidal flood. The research method that used was a case study. This research used four analysis methods, that were: (1) descriptive analysis, (2) damaged assessment method, (3) logistic regression analysis and (4) Exponential Comparison Method (ECM). The result showed that the impact of tidal flood were the disruption of daily activities and public health of the community, the decrease of income, house damage and the decreasing of housing environment condition. The total estimated of economic losses which suffered by the community of Kampung Pondok due to the tidal flood period from January to February 2013 was Rp 127.188.875. The total of prevention cost that the community Kampung Pondok issued within the last six years was Rp 22.671.570. The factors that influenced the decision of community to conduct a prevention and adaptation were the total economic losses, household income, and length of stay. There were four alternatives adaptation strategy of tidal flood based on the result of policy analysis with MPE. The alternatives were planting and maintenance mangrove, using waves breaker, develop of soil retaining wall along the river and community relocation.

Judul: Estimasi Kerugian Ekonomi Masyarakat dan Strategi Adaptasi Akibat Banjir Rob (Studi Kasus: Desa Pecakaran, Kecamatan Wonokerto, Kabupaten Pekalongan).
Abstrak: Desa Pecakaran merupakan desa yang berbatasan langsung dengan Pantai Utara Jawa yang terletak di Kecamatan Wonokerto, Kabupaten Pekalongan. Desa Pecakaran merupakan salah satu wilayah yang terkena dampak kenaikan permukaan air laut yaitu banjir rob. Peristiwa banjir rob menyebabkan masyarakat yang tinggal di Desa Pecakaran mengalami kerugian ekonomi yang cukup besar. Tujuan dari penelitian ini adalah mengestimasi nilai kerugian ekonomi masyarakat akibat banjir rob; menganalisis indeks kerentanan masyarakat terhadap banjir rob; menganalisis strategi adaptasi dalam mengurangi banjir rob. Penelitian ini menggunakan beberapa metode analisis, yaitu: metode biaya perbaikan, metode biaya kehilangan, metode biaya pengobatan, pendekatan pendapatan yang hilang, perubahan pendapatan petani tambak, dan biaya pencegahan; metode livelihood vulnerability index; serta metode perbandingan eksponensial. Hasil penelitian menunjukkan bahwa estimasi kerugian ekonomi yang dialami masyarakat Desa Pecakaran tahun 2015 sampai tahun 2017 sebesar Rp 2 080 063 790 dengan ratarata sebesar Rp 693 354 597 per tahun, sedangkan total perubahan petani tambak yang dialami masyarakat Desa Pecakaran pada tahun 2016 sebesar Rp 11 689 280 925 per tahun. Total biaya pencegahan terhadap banjir rob yang dikeluarkan masyarakat Desa Pecakaran dari tahun 2013 sampai tahun 2017 yaitu Rp 6 154 674 548, dengan rata-rata Rp 1 230 934 910 per tahun. Nilai indeks rasio Livelihood Vulnerability Index (LVI) di Desa Pecakaran sebesar 0.45 sedangkan nilai indeks rasio Livelihood Vulnerability Index-Intergovernmental of Climate Change (LVIIPCC) yaitu sebesar 0.03. Prioritas alternatif kebijakan secara keseluruhan menurut stakeholder yaitu pembuatan tanggul melintang oleh pemerintah dengan total nilai sebesar 33 859.

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
