Judul: Studi Evaluasi Program Pemberdayaan Petani Melalui Teknologi dan Informasi Pertanian (P3TIP) di Kabupaten Serang (Kasus: Desa Ciruas, Kecamatan Ciruas, Kabupaten Serang, Provinsi Banten)
Abstrak: The result of previous study on FEATI, especially regarding the introduction of PTT innovation among the paddy community, are lack of attention on the assessment of the project‟s outputs in the individual and household levels as well as in the farmer‟s institution level. This study demonstrates that of the total of 45 farmers who participated on the FEATI in Ciruas Village, the majority of them are low in their formal and non formal educational level, while their communication pattern is localit. Almost half of them belong to medium category of the social stratification (the average of land holding size was about 0.25 to 0.5 Ha). As most of them are sharecroppers, the PTT farmer‟s household are belong to the poor household. This study found that the majority of the farmers was in the medium category of their attitude regarding the PTT. However, the training on PTT‟s paddy Cultivation caused the majority of PTT‟s farmers participated on agricutural extension programes which was facilitated by UP-FMA and Gapoktan were in high category. This, in turn led to the fact that the majority of the PTT‟s farmers were high category on their knowledge on PTT. It is not followed, however, with the high level of their attitude and practice on PTT, as the majority of the farmers were on the medium category on the two aspects, 56 percent and 49 percent respectively. Further, this situation led to the fact that the majority (69 percet) of farmers were low in the level of their rice productivity and household income as well. Interestingly, however, this study found that the training of PTT‟s Paddy Cultivation facilitated the achievement of the project‟s objectives which is the higher the knowledge of farmers on PTT, the more positive their attitude on PTT, and in turn the higher the implementation of the PTT. The higher the three variables of individual project ouputs the higher the household project outputs. As this study also found that the UP-FMA and Gapoktan are still low in their performance, accordingly, the Badan Penyuluhan dan Ketahanan Pangan (BPKP) should increase their effort to empower the UP-FMA and Gapoktan Harum Mekar so the two farmer organizations could improve their capability to help their members (farmer groups) to increase their household income by developing agribusiness and business partnerships as mandated on the objective of the FEATI.

Judul: Persepsi petani dan penerapan inovasi pengelolaan tanaman dan sumberdaya terpadu padi sawah di lokasi Prima Tani, Kabupaten Serang, Provinsi Banten:
Abstrak: Upaya meningkatkan produktivitas padi lahan sawah dapat dilakukan dengan pendekatan Pengelolaan Tanaman dan Sumberdaya Terpadu (PTT). Upaya percepatan diseminasi pendekatan PTT padi pada petani, telah dilakukan dengan berbagai kegiatan seperti: gelar teknologi, model percontohan, temu lapang dan temu wicara. Selain aspek inovasi teknologi, faktor petani sebagai pelaku usahatani juga memegang peranan penting dalam menunjang keberhasilan pemanfaatan inovasi tersebut. Prasyarat yang diperlukan agar peningkatan produksi padi sesuai dengan target yang diinginkan adalah tumbuhnya kesadaran petani akan pentingnya teknologi pertanian. Proses adopsi teknologi memerlukan komunikasi yang efektif, diharapkan terjadi persamaan persepsi antara sumber pesan dengan petani sebagai penerima pesan perihal informasi yang disampaikan. Dengan persepsi yang baik diharapkan tingkat adopsi inovasi meningkat. Dengan demikian penelitian tentang persepsi petani diperlukan sebagai acuan dalam melakukan diseminasi inovasi. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang berhubungan dengan pembentukan persepsi petani tentang pengelolaan tanaman secara terpadu (PTT) pada padi, dan mengkaji hubungan antara persepsi petani dengan tingkat penerapannya. Penelitian dilakukan dilokasi Program Rintisan dan Akselerasi Pemasyarakatan Inovasi teknologi Pertanian (Prima Tani) Serang, di Desa Teras Kecamatan Carenang Kabupaten Serang, Provinsi Banten pada petani peserta PTT padi pada bulan Maret – Mei 2009. Jumlah petani responden adalah 59 petani diambil secara sensus dari populasi yang ada.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
