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: Respon Petani terhadap Metode Pengelolaan Tanaman Terpadu (PTT) Padi di Desa Pancawati Caringin Bogor
Abstrak: Riceis a commodity that has been still the staple food of Indonesia so far. Riceis also acommodity that canaffect thesocio-economic conditions, andstate politics. However,related to the currentrice commodities in Indonesia, rice store that has suffered the drawback. Farmer sare required to participatein building the strength of the national food through increased productivity. The claimis often hampered by the powerlessness of farmers in the ability to apply (adoption) the technology. Integrated Crop Management (ICM) is one of the government's efforts to realize the successful achievement of sustainable self-sufficiency through increased productivity. ICM is a participatory holistic approach tailored to site-specific conditions. Therefore, it is not a technology package that must be applied by farmers in all locations. ICM goal is to improve the livelihoods of farmers through the application of appropriate technology to local conditions. The success of a program is influenced by knowledge, skills, and attitudes of actors/doers (farmers) in the field. Research to be conducted is expected to provide feedback information to the farmers' understanding towards this methods asthe efforts to increase rice productivity. This study took place in Pancawati village Caringin bogor. Research subjects in this study are all members of farmer groups in the Pancawati village Caringin bogor. The sampling technique used is using census technique, so the respondents in this study are the entire population of the 125 farmers. Data analysis in this study uses descriptive analysis and SEM (Structural Equation Model) by using PLS program. The analysisconducted inthis study, it can be concluded thatthe responsesof farmers towards this method in improvingrice productivityare good. This can be indicated byrespondents perceptions ofthe knowledge, skillsandgood attitude. Based on the SEM PLS,the knowledge and skills affect productivity but higher skills than the loading factor productivity of knowledge that is more influenced by the skills of farmers but farmers have not been able to make modifications because of conceptual knowledge or lack of knowledge that needed assistance because it involves the application of field and field of technical skills to be successful applying the method of PTT. In the long term knowledge is also needed so that farmers can provide innovation input, modify the method of PTT, PTT method helps application problems. It is shown by the different manner in which the attitude variable does not affect productivity.

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.
