Judul: Analisis Resiliensi Ekologis Berdasarkan Perubahan Garis Pantai di Kabupaten Tangerang
Abstrak: Wilayah pesisir Kabupaten Tangerang mengalami perubahan garis pantai secara terus-menerus yang disebabkan oleh faktor alam maupun aktivitas manusia. Perubahan yang terus terjadi ini dapat mempengaruhi tingkat resiliensi ekologi yang ada di pesisir. Tujuan dari penelitian ini adalah menilai tingkat resiliensi ekologi berdasarkan dinamika perubahan garis pantai, serta kaitannya dengan penggunaan dan tutupan lahan di pesisir Kabupaten Tangerang. Analisis data terdiri atas pengolahan citra satelit Landsat, analisis penggunaan dan tutupan lahan (land use land cover/LULC), laju perubahan garis pantai menggunakan Digital Shoreline Analysis System (DSAS), pengolahan data oseanografi, dan penilaian resiliensi. Hasil penelitian menunjukkan bahwa pesisir Kabupaten Tangerang memiliki tingkat resiliensi rendah dengan dinamika perubahan garis pantai lebih dominan erosi daripada akresi. Kawasan yang mengalami erosi tinggi cenderung tidak resilien dengan LULC dominan adalah lahan tambak dan sedikit mangrove, sedangkan kawasan yang mengalami akresi tinggi memiliki tingkat resiliensi tinggi dengan LULC muara sungai., The coastal area of Tangerang Regency experiences continuous changes in the coastline caused by natural factors and human activities. These ongoing changes can affect the level of resilience on the coast. The purpose of this study was to assess the level of resilience based on the dynamics of shoreline change, as well as its relation to land use and land cover on the coast of Tangerang Regency. Data analysis consisted of processing Landsat satellite imagery, land use and land cover (LULC) analysis, shoreline change rate using Digital Shoreline Analysis System (DSAS), oceanographic data processing, and resilience assessment. The results showed that the coast of Tangerang Regency has a low level of resilience with the dynamics of shoreline change being more dominant in erosion than accretion. Areas that experience high erosion tend to be less resilient with dominant LULC being ponds and few mangroves, while areas experiencing high accretion have high resilience levels with LULC of river mouths.

Judul: Prediksi Laju Abrasi Dengan Menggunakan Citra Satelit di Kabupaten Tangerang Provinsi Banten
Abstrak: Shoreline change is the result of a combination of natural processes (waves, tides, currents and sedimentation) and humans. Tangerang regency, as one district that has a long coast until 51 km can not be separated from environmental damage that occurs due to coastal erosion. purpose of this study was to identify the changes that occur in the shoreline along the coastal areas of Tangerang regency by utilizing satellite imagery, Geographic Information Systems. and predict the rate of erosion along coastal areas of Tangerang regency. This study is expected to provide an overview of the condition of coastal areas against the threat of Tangerang regency abrasi. Depend on the result, predictive analysis of Kronjo district has an average erosion rate of 16.3 m / year, abrasion rate of the kemiri is 9,295 m / year, Mauk abrasion average rate of 20.9 m / year, Sukadiri with an average erosion rate of 5.2 m / year, Paku Haji abrasion average rate of 14.3 m / year, in Teluk Naga district average erosion rate of 19.67 m / year and average speed of abrasion on Kosambi is 3.2 m / year. Based on these results indicated mangrove forest damage has occurred, so it is necessary to protect coastal areas handling both made by building a protective beach or in a natural way by planting mangroves.

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%.
