Judul: Resiliensi Nafkah Rumahtangga Petani Hutan Rakyat di Kecamatan Giriwoyo, Wonogiri
Abstrak: Community forest is forest management that not only considering the aspect of ecology but also economic aspect, likely increasing income, and improving the welfare of farmers. Community forest famer household not only use natural capital in livelihood activities, but also used other livelihood asset that can be used to produce income. The method used is a combination of quantitative approach by asking questionnaires and qualitative with in-depth interviews. The purpose of this research is knowing resilience built the household form livelihood asset. Resilience defined as ability individual or group to survive of shocks and crisis.The result showed that resilience affected by ownership of livelihood asset and household incomes. Livelihood assets used by household to livelihood strategy, untill can building livelihood resilience’s household.

Judul: Analisis Resiliensi Nafkah Rumahtangga Petani Hutan Rakyat
Abstrak: Penelitian ini dilaksanakan di Kabupaten Wonosobo, Jawa Tengah, khususnya di Desa Kalimendong dan Desa Besani, Kecamatan Leksono. Penelitian ini bertujuan untuk melihat bagaimana struktur dan strategi nafkah rumahtangga petani. Penelitian ini juga menganalisis modal nafkah yang dimiliki dan dimanfaatkan oleh rumahtangga petani terhadap resiliensi rumahtangga petani. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dan didukung dengan metode kualitatif. Metode kuantitatif melakukan pendekatan survei dengan menggunakan kuesioner. Sedangkan untuk metode kualitatif menggunakan metode wawancara mendalam. Pendekatan lain yang digunakan adalah melalui obervasi lapang di lokasi penelititan. Hasil penelitian menunjukan bagaimana struktur, strategi nafkah rumahtangga petani, pengaruh modal nafkah terhadap tingkat resiliensi, dan faktor-faktor yang mempengaruhi tingkat resiliensi rumahtangga petani di kedua desa. Faktor yang mempengaruhi tingkat resiliensi di Desa Kalimendong yaitu modal sosial, modal finansial (tingkat pinjaman dan pendapatan kayu), modal fisik (asset produksi dan asset non produksi). Sedangkan faktor yang mempengaruhi tingkat resiliensi rumahtangga petani di Desa Besani yaitu modal manusia, modal sosial, dan modal fisik (asset produksi).

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
