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 pengelolaan hama dan penyakit pepaya di Kecamatan Rancabungur, Bogor.
Abstrak: Pepaya merupakan salah satu tanaman buah yang banyak ditanam dan dikonsumsi di Indonesia. Bogor merupakan salah satu daerah sentra produksi tanaman pepaya di Indonesia. Serangan hama dan penyakit merupakan masalah terpenting yang dapat menghambat produksi dari tanaman pepaya. Penelitian ini bertujuan memperoleh informasi dan analisis tentang pengetahuan, sikap, dan tindakan petani responden dalam pengelolaan hama dan penyakit tanaman pepaya di Kecamatan Rancabungur, Bogor. Penelitian dilaksanakan di beberapa desa di Kecamatan Rancabungur yaitu Rancabungur, Bantar Sari, Bantar Jaya, dan Mekar Sari. Penelitian berlangsung dari Mei hingga Agustus 2010. Data diperoleh melalui wawancara dengan 40 petani menggunakan kuesioner tentang karakteristik petani, karakteristik usaha tani, budidaya tanaman, dan pengelolaan hama dan penyakit. Data yang diperoleh disajikan secara deskriptif dan dianalisis dengan menggunakan uji χ2 (chi-square) untuk melihat hubungan antara umur, pendidikan, pengalaman usaha tani, keanggotaan kelompok tani (gapoktan), dan keikutsertaan petani dalam Sekolah Lapangan Pengendalian Hama Terpadu (SLPHT) terhadap

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.
