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.

Judul: Faktor Penentu Keterlibatan Generasi muda dalam Pertanian Tanaman Pangan.
Abstrak: Fenomena aging farmer atau penuaan petani sudah menjadi perhatian Indonesia dan negara-negara lainya. Indonesia menghadapi permasalahan menurunnya jumlah tenaga kerja muda pertanian. Banyak alasan yang mendasari generasi muda tidak mau bekerja di sektor pertanian, di antaranya adalah citra sektor pertanian yang kurang bergengsi dan kurang bisa memberikan imbalan memadai dan cara pandang tenaga kerja muda telah berubah di era perkembangan masyarakat post modern. Disisi lain, ada juga generasi muda yang termotivasi dan berminat menjadi petani muda. Tujuan dari penelitian ini untuk menganalisis faktor penentu keterlibatan generasi muda dalam pertanian tanaman pangan. Faktor yang dianalisis berupa faktor internal dan eksternal. Faktor Internal meliputi pendidikan, pengalaman bertani, jenis kelamin, status pernikahan, dan motivasi menjadi petani. Sedangkan, faktor eksternal meliputi aktivitas utama orangtua, dukungan orangtua, pengasaan lahan orang tua, dukungan masyarakat dan teknologi. Penelitian ini dilakukan dengan metode kuantitatif dan kualitatif. Hasil penelitian ini menunjukkan bahwa terdapat empat faktor yang signifikan mempengaruhi keterlibatan generasi muda dalam pertanian tanaman pangan di antaranya adalah: pendidikan, pengalaman bertani, motivasi untuk menjadi petani dan dukungan orangtua.

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.
