Judul: Pengetahuan, Sikap, dan Tindakan Petani Terhadap Organisme Pengganggu Tanaman Palawija dan Sayuran di Kecamatan Rancabungur, Bogor.
Abstrak: Crops and vegetables are prospective commodities to be developed in the future because of its increasing demands. Pests and diseases become one of main problems in increasing plant’s productivity. Farmer and communities as farming actors need knowledge about integrated pest management to reduce pesticides dependence. This study aims at analyzing and obtaining information on knowledge, attitude and action of respondents in controlling pests and diseases in Bantar Kambing village and Pasir Gaok village, Rancabungur sub-district, Bogor, research was conducted from September to November 2013. The study were conducted by direct structured and unstructured interviews to 40 respondent farmers. Region were determined directly based on crops and vegetables location. Pests and diseases observation was conducted by observing types of pests, diseases, and symptoms. Most of the farmers were more than 40 years old and had been farming for 22 years with educational background of elementary school. Averages of land ownership status are owned by farmers and other part is only as a labour. About 20 percent of farmer have participatedon SLPHT training. The farmers who have never participated on training was a factor in farmers lack of knowledge. Despite of less knowledge on integrated pest management (IPM), farmers implemented plants rotation technique and mulching in plants cultivation. Most of farmers believed in and still using chemical pesticides to reduce pests and diseases on field even though they knew it was harmful to the environment and farmers

Judul: Pengetahuan, Sikap Dan Tindakan Petani Dalam Pengendalian Hama Terpadu Di Kecamatan Rancabungur Kabupaten Bogor
Abstrak: Kecamatan Rancabungur merupakan sentra produk pertanian dataran rendah di kabupaten Bogor, terutama sayuran. Salah satu komponen pertanian yang berkelanjutan adalah pengendalian Hama Terpadu (PHT). PHT merupakan program nasional. Evaluasi PHT yang tidak berbasis komoditi belum pernah diteliti. Oleh sebab itu penelitian ini bertujuan mengevaluasi status penerapan PHT di Kecamatan Rancabungur dan mengetahui keterkaitan antara umur, pendidikan dan keikutsertaan dalam program penyuluhan dengan tingkat pengetahuan, sikap dan pengembangan tindakan PHT. Penelitian dilakukan dengan metode survei terhadap 60 responden yang dipilih secara acak menggunakan instrumen berupa borang yang berisi pertanyaan tentang pengetahuan PHT, sikap dan tindakan PHT. Data diolah menggunakan Microsoft Excel 2013. Keterkaitan antara dua peubah dianalisis dengan uji chi-square pada =0,05. Petani di Kecamatan Rancabungur menanam tanaman sayuran dan buah-buahan, selain tanaman pangan dan palawija. Petani memiliki pengetahuan budidaya yang tergolong baik. Petani responden kebanyakan tergolong pemuda berumur antara 30-40 tahun dan berpendidikan Sekolah Dasar. Ilmu bertani para petani diperoleh secara turun temurun dan kebanyakan belum pernah mengikuti pelatihan. Kebanyakan mereka telah menjadi petani selama lebih dari 5 tahun. Kebanyakan mereka mengusahakan tanam sayuran dengan luasan lahan usaha kurang dari 5000 m2. Dengan karakteristik seperti itu, kebanyakan petani tergolong memiliki pengetahuan PHT yang baik, sikap yang sesuai dengan prinsip-prinsip PHT dan telah mengembangkan tindakan PHT dengan baik. Pengetahuan, sikap dan tindakan PHT tidak berkaitan dengan umur dan pendidikan. Keikutsertaan dalam program penyuluhan juga tidak berkaitan dengan pengetahuan PHT dan sikap petani, namun berkaitan dengan pengembangan tindakan PHT. Oleh sebab itu program penyuluhan sebaiknya ditingkatkan agar adopsi prinsip-prinsip PHT lebih baik.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
