Judul: Efektivitas Media Komunikasi Bagi Petani Padi di Kecamatan Gandus Kota Palembang (Kasus Program Ketahanan Pangan)
Abstrak: Media communication is a channel or path through which messages to get to the audiences. Communication to be effective if it can have an impact that are to reach the knowledge, attitudes and actions of audience. On the cognitive effects include increased awareness, learning and additional knowledge. Affective include effects associated with emotions, feelings and attitudes. Conative include effects associated with the behavior and intentions to do something in a certain way rightly. The research was carried out in June until August 2012. The objectives of the research were : 1) to identify factors correlated to the effectiveness of media communication for the rice farmers, 2) to measure effectiveness of media communications for the rice farmers, 3) to analyze the correlation between media exposure and effectiveness of media communications, 4) to analyze the correlation between media communications evaluated and effectiveness of media communication. The location of the sample was determined purposively. The number of the farmers were 76 taken by simple random sampling. The important research findings were : 1) factors correlated to the effectiveness of media communication for the farmers rice are age, experiences, television exposure, and appropriateness of object matters given by the needs of the farmers, 2) Food security in Gandus is considered as in good category.

Judul: Efektivitas Komunikasi Dalam Pelaksanaan Kegiatan Penguatan Lembaga Distribusi Pangan Masyarakat(Kasus Gabungan Kelompok Tani Maju Bersama Desa Bumiharjo Kecamatan Batanghari Kabupaten Lampung Timur)
Abstrak: Government Regulation No. 68 of 2002 on food security stated that food needs fulfillment is not only the matter of production but also distribution issues, which cause many problems. The objectives of the research were to describe strengthening program of food community distribution institutional (P-PLDPM), analyze forms of communication of Joint Farmer’s Group (Gapoktan) in the program and analyze communication effectiveness of in the program. The research was designed as a descriptive and correlational survey research. The study site selection was purposively selected namely Gapoktan Maju Bersama of Bumiharjo Village, Batanghari Subdistrict, East Lampung District. Primary data collection and field observations were carried out during April to June 2012. Respondents of this study amounted to 83 farmers who know the P-PLDPM. The data used in this research consisted of primary data and secondary data. Data analysis applied descriptive statistics and Spearman Rank Correlation Analysis using Excel and SPSS 15.0 program for Windows. Gapoktan Maju Bersama have been implementing the strengthening community food distribution institutional program since 2010 up to date. The most frequent communication forms, which were performed by Gapoktan Maju Bersama management was group meeting with the field companion and farmer members.In the group meeting, a discussionalways takes place.Farmers' level of understanding on the P-PLDPM activities determined the communication effectiveness, because it could significantly change knowledgeand behavior levels.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
