Judul: Strategi Penghidupan dan Resiliensi Nafkah Rumah Tangga Petani di Kawasan Banjir (Kasus: Desa Sumber Urip, Kecamatan Pebayuran, Kabupaten Bekasi Utara)
Abstrak: Rumah tangga petani di kawasan banjir mengalami kerugian dan terhambat pendapatannya yang disebabkan terendamnya lahan pertanian oleh banjir yang menyebabkan kerentanan pada sistem nafkah. Rumah tangga melakukan berbagai strategi nafkah serta memanfaatkan sumber-sumber nafkah yang tersedia agar dapat bertahan dan segera pulih dari krisis. Tujuan dari penelitian ini adalah untuk menganalisis struktur nafkah, strategi nafkah dan faktor-faktor yang mempengaruhi tercapainya resiliensi nafkah rumah tangga petani di kawasan banjir, Desa Sumber Urip, Kecamatan Pebayuran. Penelitian ini merupakan penelitian kuantitatif yang didukung dengan kualitatif. Teknik pengumpulan data melalui kuesioner untuk data kuantitatif dan wawancara mendalam untuk data kualitatif. Hasil penelitian ini menunjukan bahwa faktor yang mempengaruhi resiliensi rumah tangga petani di kawasan banjir adalah persentase pendapatan pertanian sawah terhadap total pendapatan rumah tangga, jumlah sumber pendapatan rumah tangga, jumlah organisasi/lembaga yang diikuti rumah tangga, dan jumlah kegagalan menghadapi krisis., Farmer households in flooded areas suffer losses and have reduced income as a result of agricultural land flooding, which exposes the livelihood system to vulnerability. Households use various adaptation mechanisms and take advantage of available sources of income to survive and recover quickly from the crisis. The purpose of this study is to analyze the structure of income, livelihood strategies , and factors that support the achievement of household livelihood resilience among farmers in flooded areas, Sumber Urip Village, Pebayuran District. This is a quantitative study that is supported by qualitative data. Technique of collecting data is through questionnaires for quantitative and in-depth interviews for qualitative. The results of this study indicate that the percentage of rice farming income to total household income, the number of sources of household income, the number of organizations/institutions in which households participate, and the number of failures to face the crisis are the factors that influence the resilience of farmer households in flooded areas.

Judul: Livelihood Strategy and Welfare of Farmers' Households Affected by Tidal Flood (Case: Pesanggrahan Village, Wonokerto Districts, Pekalongan Regency, Jawa Tengah Province)
Abstrak: Banjir rob di Desa Pesanggrahan terjadi karena pengaruh dari hulu dan kenaikan muka air laut sebagai akibat dari perubahan iklim. Hal ini berdampak terhadap produktivitas pertanian hingga menghilangnya beberapa mata pencaharian petani, sehingga petani perlu menerapkan strategi nafkah untuk menghadapi dampak dari perubahan iklim. Penelitian ini bertujuan untuk mendeskripsikan perkembangan terjadinya banjir rob, menganalisis modal nafkah yang dimanfaatkan rumah tangga petani, menganalisis strategi nafkah yang diterapkan rumah tangga petani, dan menganalisis kesejahteraan rumah tangga petani. Metode penelitian ini adalah pendekatan kuantitatif yang didukung oleh data kualitatif. Data diperoleh dengan wawancara mendalam kepada 4 informan dan kuesioner kepada 35 rumah tangga petani Desa Pesanggrahan. Hasil penelitian menunjukkan bahwa banjir rob banyak memberikan dampak negatif bagi kehidupan rumah tangga petani serta menghilangnya beberapa mata pencaharian. Strategi nafkah yang diterapkan rumah tangga petani adalah diversifikasi mata pencaharian. Modal nafkah diperlukan untuk menerapkan strategi nafkah, namun tidak ada hubungan kepemilikan modal nafkah dengan keberagaman strategi nafkah. Kesejahteraan berhubungan dengan keadaan berupa banjir rob yang mengganggu kegiatan sosial ekonomi responden., Tidal flooding in Pesanggrahan Village occurred due to the influence of upstream and sea-level rise as a result of climate change. This has an impact on agricultural productivity and the loss of some farmers' livelihoods, so farmers need to implement livelihood strategies to deal with the impacts of climate change. This study aims to describe the development of tidal flooding, analyze the livelihood capital used by farmer households, analyze the livelihood strategies applied by farmer households, and analyze the welfare of farmer households. This research method is a quantitative approach supported by qualitative data. Data were obtained by in-depth interviews with 4 informants and questionnaires to 35 farmer households in Pesanggrahan Village. The results showed that the tidal flood harmed the household life of farmers and the loss of several livelihoods. The livelihood strategy applied by farming households is livelihood diversification. Livelihood capital is needed to implement livelihood strategies, but there is no relationship between livelihood capital ownership and the diversity of livelihood strategies. Welfare is related to conditions in the form of tidal floods that disrupt the socio-economic activities of the respondents.

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
