Judul: Hubungan beberapa karakteristik penyuluh pertanian lapangan dan keefektifan mereka melaksanakan kunjungan lapangan kelompok tani hamparan di wilayah Kabupaten Dati II Bogor
Abstrak: Kunjungan lapangan ke kelompoktani hamparan yang meru pakan bagian dari tata kerja penyuluhan pertanian Sistim Kerja Latihan dan Kunjungan bertujuan meningkatkan pengeta huan dan keterampilan petani menuju tercapainya petani yang tangguh. Keberhasilan para penyuluh meningkatkan pengeta- huan dan keterampilan para petani melalui acara kunjung- an lapangan dipengaruhi oleh tingkat keefektifan pelaksana an acara kunjungan itu sendiri. Dari sekian banyak faktor yang dapat mempengaruhi keefektifan pelaksanaan acara kun Jungan lapangan ke kelompoktani hamparan, diduga karakter- istik Penyuluh Pertanian Lapangan merupakan faktor yang sa ngat penting. Karakteristi-karakteristik tersebut yaitu penampilan, kekosmopolitan, sikap, pengetahuan, pendidikan formal orang tua, lama menetap di pedesaan sebelum menjadi Penyuluh Pertanian Lapangan, pengalaman kerja sebagai pe- nyuluh dan kegiatan sosial yang dilakukan Penyuluh Perta nian Lapangan di luar kegiatan dinas. Sedangkan unsur-un- sur yang digunakan untuk penetuan tingkat keefektifan..dst

Judul: Faktor-faktor yang mempengaruhi perilaku penyuluh pertanian lapangan dalam program supra insus  : (Studi kasus di Wilayah Kerja Balai Penyuluhan Pertanian Patrol, Kab. Indramayu, Jawa Barat)
Abstrak: Tujuan praktek lapang ini adalah untuk, (1) Mempela- jari keterkaitan karakteristik individu dan lingkungan de- ngan perilaku PPL, serta terhadap tingkat produktifitas padi oleh petani khususnya dan penerapan 10 Paket Teknologi Supra Insus pada umumnya, (2) Menemukan kelemahan-kelemahan di dalam sistem penyuluhan terutama yang berkaitan dengan kondisi dan perilaku Penyuluh Pertanian Lapangan dalam bertugas. Metode penelitian ini adalah studi kasus dengan mewa- wancarai semua PPL (17 orang) yang terdapat di WKBPP Pat- rol. Selain itu juga dilakukan wawancara terhadap 17 о- rang Kontak Tani (informan petani) serta para Fenyuluh Pertanian Urusan Programa (PFUF)/Kepala BPP, untuk menilai perilaku PPL atau tingkat keberhasilan PPL dalam pelaksa- naan kegiatan penyuluhan yang menjadi tugasnya. Instansi- instansi lain yang terkait dengan Frogram Supra Insus di wilayah ini menjadi sumber data sekunder dalam studi ini. lelaksanaan penyuluhan di WKBPF Patrol lebih menekankan kepada kegiatan "penyuluhan terpadu" di tingkat desa ...

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
