Judul: Faktor-Faktor yang Menentukan Keterlibatan Pemuda Pedesaan pada Kegiatan Pertanian Berkelanjutan
Abstrak: Sustainable agriculture is one of national ideals in the realization of food self-suffiency in Indonesia. Sustainable agriculture will not be realized without the involvement of youth in agricultural activities, which includes the activities of land and seed preparation, maintenance, and harvesting. Agricultural activities must be able to meet the economic needs, maintaining land fertility, and recognized by society as decent job. The purpose of this research was to analyze the factors that determine the involvement of rural youth in sustainable agricultural activities. To achieve that, the research methodology that being used are qualitative and quantitative. Methodology used for quantitative is survey approach. Quantitative data were processed using regression test, rank spearman test, and cross tabulation. Meanwhile, methodology used for qualitative is in-depth interview approach. Data obtained from this method are being reduced, presented, and drawn for conclusion. Result of the research showed involvement of youth in agricultural activities decrease. This happens due to parental socialization and low cohesiveness peers. Agricultures is considered as a job that is not economically viable. Therefore, it needs the attention of various side to improve the socialization of agriculture, and coordinating institution to facilitate youth to share information about agriculture.

Abstrak: The study about youth attitude was conducted in order to identify about kinds of behavior that would be performed by the youth towards agricultural livelihood. By identifying their attitude, people could be able to estimate response from youth about agricultural livelihood. The objectives of this study were: 1). To identify youth attitude towards agricultural activities. 2). To identify internal characteristics of youth, socialization from parents, mass media exposure, and interaction with peers. 3). To analyze the correlations between internal factors and youth attitude towards agricultural livelihood. 4). To analyze the correlations between socialization from parents, mass media exposure, and interaction with peers with youth attitude towards agricultural livelihood. 5). To analyze the correlations between perception toward rural condition and youth attitude towards agricultural livelihood. A number of 65 respondents were taken as sample. This study resulted several important outputs namely, 1). Majority of youth supported and agreed to work at agricultural setting 2). Majority of the youth were categorized late adolescence, low level of education, their parents were owner of their own farmland, low level in farmland mastery, low level in cosmopolite, low frequency from parents on telling about agriculture, average level on youth involvement in helping parents in farming activities, low frequency on mass media exposure, less than 20 minutes in every opportunity of watching television and also listening radio, low interaction with peers on agricultural sector, and good perception toward rural condition 3). There were several variables correlated to youth attitude towards agricultural livelihood i.e. age, gender, youth involvement in helping parents in farming activities, intensity on watching television, closeness with peers, and perception towards further condition of agricultural development.

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.
