Judul: Tingkat Perubahan Perilaku pada Pendengar Radio AGRI FM Program “Remaja (Request malam aja)”.
Abstrak: Program Remaja (Request malam aja) merupakan salah satu program siaran di AGRI FM yang bertujuan memenuhi kebutuhan informasi dan hiburan bagi mahasiswa Institut Pertanian Bogor. Untuk meningkatkan jumlah pendegar, pengelola AGRI FM membuka kesempatan pendengar untuk ikut berkomentar pada setiap informasi atau topik yang sedang dibahas. Tujuan dari penelitian ini adalah menganalisis perubahan pada setiap tingkat perubahan perilaku yang terjadi setelah pendengar mendengarkan program Remaja (Request malam aja) di AGRI FM. Penelitian ini menggunakan pendekatan kuantitatif survei dan pendekatan kualitatif dengan melakukan wawancara mendalam. Hasil penelitian menunjukan bahwa terjadi perubahan perilaku pada tingkat pengetahuan dan kecendrungan sikap khalayak pada program Remaja (Request malam aja) di AGRI FM. Perubahan perilaku tersebut terjadi karena dipengaruhi oleh faktor karakteristik khalayak program tersebut dan faktor karakteristik siaran radio itu sendiri.

Judul: Perilaku Remaja dalam Mendengarkan Radio Komunitas (Kasus Pendengar BeTe Radio di Kelurahan Tegal Gundil, Kecamatan Bogor Utara, Kota Bogor, Provinsi Jawa Barat)
Abstrak: This research aimed to analyze the relation between teenager behaviors on community radio listening activity. This research goals are (1) to identify the pattern of listening activity on community radio among teenager (2) to analyze the relation between listeners characteristics and broadcast format assessment by listening community radio (3) to analyze the relation between community radio listeners pattern with the teenager behaviors, and (4) to identify the listeners expectations towards community radio. The main method of this research is quantitative approach, and qualitative approach as supporting. Research and observationshow that the teenagers who are listening to the BeTe community radio have low level of listening activity pattern. Affective level and social network were also relatively low. Related to the listeners characteristics, the research result showed that gender does not have any relation with the pattern of radio listening activity. Beside that, age, media ownership, and main activities have significant relation towards pattern of radio listening activity. To assess broadcast format variable, pshycological proximity does not have any relation significantly with the pattern of radio listening activity. In the pattern of radio listening activity variable which is consist of listening frequency, listening duration, program choices, participation on the program have significant relation with to point of view, affective, and social network of BeTe Radio listeners.

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.
