Judul: HubunganKerentanan dengan Strategi Adaptasi Nelayan Kecil Menghadapi Banjir Rob.
Abstrak: Kenaikan permukaan air laut sebagai implikasi dari perubahan iklim dapat mengakibatkan terjadinya rob terhadap seluruh wilayah pesisir Indonesia. Banjir rob dapat menciptakan kerentanan pada masyarakat. Kerentanan merupakan kondisi ketika sistem diguncang oleh gangguan dari luar sistem hingga melewati batas kritis. Kerentanan (vulnerability) ini dibagi atas tiga komponen, yaitu (1) tingkat paparan (exposure); tingkat kepekaan (sensitivity); dan kemampuan adaptasi (capacity of response). Nelayan mempunyai kapasitas dan strategi adaptasi yang berbeda dalam merespon bencana banjir rob Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif dan didukung dengan pendekatan kualitatif. Penelitian ini menggunakan metode survei melalui wawancara terhadap responden dengan kuisioner. Penelitian ini mengambil responden secara aksidental dengan jumlah responden sebanyak 40 orang di Desa Tratebang, Pekalongan. Hasil penelitian menunjukkan bahwa responden memiliki tingkat kerentanan sedang pada aspek paparan dan sensitivitas. Pada aspek kapasitas adaptif memiliki tingkatan yang rendah. Hasil analisis uji korelasi, hubungan yang signifikan ditunjukkan oleh variabel tingkat paparan dengan strategi adaptas

Judul: Strategi Adaptasi Rumah Tangga Petani dan Non Petani Terdampak Banjir Rob
Abstrak: Dampak perubahan iklim semakin terasa di setiap negara di dunia, termasuk Indonesia. Salah satu bentuk perubahan iklim di Indonesia adalah banjir rob yang terjadi di pesisir Indonesia, sehingga penduduk yang terdampak harus melakukan adaptasi. Tujuan penelitian ini adalah untuk menjelaskan upaya masyarakat pesisir dalam mengatasi banjir rob. Data penelitian dikumpulkan dengan survey pada rumah tangga petani dan non petani di Desa Timbulsloko, Kecamatan Sayung, Kabupaten Demak, Jawa Tengah. Hasil dari penelitian ini adalah tidak ada perbedaan strategi adaptasi yang dilakukan oleh rumah tangga petani dan non petani. Rumah tangga petani dan non petani beradaptasi dengan banjir rob dengan melakukan strategi fisik seperti mengurug lantai rumah dan strategi ekonomi dengan menambah pendapatan dari pekerjaan di bidang non pertanian. Pekerjaan non pertanian menjadi pilihan bagi kepala rumah tangga dan anggota keluarga lain karena pekerjaan pertanian yang tersisa hanya menjadi nelayan setelah tanah pertanian dan tambak terendam banjir rob.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
