Abstrak: Kabupaten Pasuruan memiliki potensi sumber daya alam berupa DAS Rejoso. Daerah aliran sungai ini mendukung mata pencaharian masyarakat di wilayah pertanian, peternakan dan kehutanan. Kecamatan Winongan dan Gondang Wetan merupakan bagian dari wilayah hilir DAS Rejoso yang sebagian besar merupakan lahan pertanian. Petani di daerah ini menghadapi kendala teknis yang menyebabkan rendahnya produktivitas pertanian. Mereka juga menghadapi masalah penggunaan air akibat kegiatan pengeboran yang tidak terkendali. Situasi ini telah menginisiasi program konservasi yang dilakukan oleh World Agroforestry Center (ICRAF), yaitu Gerakan Rejoso Kita, dengan tujuan utama untuk meningkatkan praktik budidaya pertanian yang ada dengan sistem pertanian berkelanjutan. Program ini telah berhasil dilaksanakan di sebelas desa dan hasilnya menunjukkan bahwa desa-desa tersebut berpotensi untuk dikembangkan sebagai kawasan agrowisata berbasis pertanian berkelanjutan dengan memperhatikan aspek pendidikan, rekreasi, dan pelestarian lanskap. Tujuan dari penelitian ini adalah untuk menganalisis keberlanjutan dan kesesuaian kawasan ini untuk agrowisata dan membuat rencana lanskap untuk mendukung pengembangan agrowisata. Analisis ini menggunakan metode spasial dan kualitatif terhadap aspek fisik, biofisik, serta preferensi masyarakat dan calon wisatawan. Hasil analisis menunjukkan bahwa di antara sebelas desa tersebut, Desa Gading, Lebak, dan Tenggilis Rejo merupakan desa yang paling potensial untuk pengembangan agrowisata. Desa-desa tersebut selanjutnya ditetapkan sebagai kawasan agrowisata inti, sedangkan desa-desa dengan nilai potensi sedang dan rendah akan menjadi kawasan pendukung dan penyangga. Hasil akhir dari penelitian ini adalah masterplan pengembangan agrowisata di Kecamatan Winongan dan Gondang Wetan serta rencana lanskap pengembangan agrowisata pada Desa Gading., The Pasuruan Regency has potential natural resources in the form of Rejoso watershed. This watershed supports people‘s livelihood in the region of agriculture, livestock and forestry. The Winongan and Gondang Wetan subdistricts are part of the Rejoso watershed downstream area which predominantly agricultural land. Farmers in these area are facing technical problems that has caused the low agricultural productivity. They also encounter water use problems due to uncontrolled drilling activities.These situation have initiated a consevation program conducted by the World Agroforestry Centre (ICRAF), namely Gerakan Rejoso Kita, with main aim to improve the existing agricultural cultivation practices using sustainable agricultural system. The program has been succesfully implemented on eleven villages and the results show that the villages are potential to be doveloped as agritourism area based on sustainable agriculture considering the aspects of education, recreation, and landscape preservation. The objective of this research are to analyze the sustainability and suitability of this area for agritourism and to make a landscape plan to support agritourism deveopment. The analysis applied spatial and qualitative methods over physical, bio-physical aspect, and the preferences of people and potential tourists. The analysis showed that among the eleven villages, Gading, Lebak, and Tenggilis Rejo were the most potential villages for agritourism development. These villages subsequently designated as main agritourism zone, while villages with medium and low potential values will become supporting and buffer zones. This final output of this study are the master plan of agritourism development for Winongan and Gondang Wetan sub-districts and a landscape plan for agritourism development in Gading village.

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
