Judul: Resiliensi Nafkah Rumahtangga Petani di Kawasan Rawan Bencana Rob, Kecamatan Kampung Laut, Kabupaten Cilacap
Abstrak: The purpose of this study was to determine adopted livelihood reselience by farmer household which correlated with their livelihood asset. This study also determine how both component influencing livelihood strategy and household income from agricultural sector and non-agricultural sector in Klaces and Lempong Pucung village. This study combined quantitative approach using questioner method and qualitative approach using in-depth interview method. The result of this study explained livelihood asset used by farmers in both village highly influencing their livelihood activities. According of three former aspect of livelihood strategy, there was difference of both village. Klaces dominated by non-farm sector. In the other hand, Lempong Pucung dominated by off-farm sector. The number of contribution of agricultural sector relatively lower than non-agricultral sector

Judul: Strategi, Kerentanan, dan Resiliensi Nafkah Rumahtangga Petani di Daerah Rawan Bencana Banjir
Abstrak: Banjir merupakan suatu bencana alam yang memberikan berbagai dampak terhadap kehidupan, khususnya bagi keberlangsungan hidup rumahtangga petani. Petani dalam melakukan usahataninya tentunya sangat bergantung dengan keadaan alam dan cuaca sekitar. Bencana banjir tentunya memberi dampak karena dapat membuat hasil panen menurun bahkan sampai terjadinya gagal panen. Menghadapi keadaan tersebut menuntut rumahtangga petani untuk menentukan struktur nafkah yang dilakukan dan menuntut rumahtangga petani menentukan bagaimana melakukan strategi nafkah dalam upaya mempertahankan dan meningkatkan sumber nafkah yang ada. Strategi nafkah adalah cara seseorang atau kelompok untuk memenuhi kebutuhan mereka atau mencapai peningkatan hidup. Strategi nafkah yang dilakukan akan berpengaruh terhadap kerentanan suatu rumahtangga dan memiliki hubungan dengan ketahanan (resiliensi) rumahtangga petani dalam menghadapi situasi bencana banjir. Struktur nafkah dan strategi nafkah rumahtangga petani yang tinggal di kawasan terpapar banjir dapat saja berbeda dengan wilayah lain yang tidak mengalami situasi krisis atau bencana banjir. Tujuan dari penelitian ini adalah untuk menganalisis strategi, kerentanan dan resiliensi nafkah rumahtangga petani di wilayah rawan bencana banjir.

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
