Judul: Farmer's and Farmer's Children's Perception of Interest in Working in the Agricultural Sector
Abstrak: Petani merupakan aktor penting dalam keberlanjutan pangan dan pertanian. Namun terjadi penuaan petani dan penurunan minat generasi muda terhadap pertanian. Demi keberlanjutan sektor pertanian, regenerasi petani ini menjadi isu penting yang dibahas perlu untuk segera direalisasikan. Penurunan minat petani disebabkan oleh berbagai faktor yaitu faktor internal dan eksternal. Penelitian ini bertujuan untuk menganalisis bagaimana persepsi anak petani terhadap minat kerja di sektor pertanian. Metode yang digunakan yaitu metode kuantitatif dengan instrumen kuesioner dan didukung dengan data kualitatif menggunakan wawancara mendalam serta observasi. Metode ini dipilih untuk melihat pengaruh faktor internal dan eksternal terhadap persepsi dan memperkuat analisis tersebut menggunakan data kualitatif. Anak petani melihat sektor pertanian dan petani sebagai pekerjaan yang kurang menjanjikan dari segi pendapatan, tetapi sangat membantu untuk memenuhi kebutuhan primer. Anak petani tidak memiliki kemauan untuk bekerja di sektor pertanian namun merasa hal tersebut adalah keharusan untuk bertahan hidup. Karakteristik individu dan faktor eksternal tidak berpengaruh signifikan terhadap persepi anak petani, Farmers are essential actors in the sustainability of food and agriculture. However, there is an aging of farmers and a decline in the interest of the younger generation in agriculture. For the sake of the sustainability of the agricultural sector, farmer regeneration is an important issue that needs to be discussed and realized immediately. The decline in farmer interest is caused by various factors, namely internal and external factors. This study analyzes how farmer children perceive interest in working in the agricultural sector. The method used is quantitative, with a questionnaire as an instrument, and is supported by qualitative data using in-depth interviews and observation. This method was chosen to see the influence of internal and external factors on perceptions and to strengthen the analysis using qualitative data. Farmers' children see the agricultural and farming sectors as less promising jobs in terms of income but are very helpful in meeting primary needs. Farmers' children do not have the will to work in the agricultural sector but feel it is a must for survival. Individual characteristics and external factors have no significant effect on the perceptions of farmer children

Judul: Persepsi dan Minat Kerja Anak Petani di Sektor Pertanian Hortikultura
Abstrak: Sektor pertanian adalah sebuah sektor yang penting bagi keberlangsungan kehidupan masyarakat negara, khususnya pertanian hortikultura. Kendati demikian, terdapat masalah yaitu meningkatnya usia rata-rata petani dan menurunnya minat generasi muda terhadap dunia pertanian. Oleh karena itu, regenerasi petani menjadi isu yang penting untuk dibahas. Penelitian ini melihat karakteristik diri anak petani menjadi faktor yang berhubungan terhadap minat dan keputusan anak petani berkontribusi di sektor pertanian. Tujuan dari penelitian ini adalah melihat pengaruh karakteristik individu dan faktor eksternal terhadap aspek kognisi, konasi, dan afeksi sebagai minat kerjanya. Metode yang digunakan dalam penelitian ini yaitu metode kuantitatif dengan instrumen kuesioner dan didukung dengan data kualitatif melalui wawancara mendalam serta observasi. Hasil dari penelitian ini adalah terdapat hubungan antara karakteristik diri, persepsi, dan minat anak petani. Karakteristik diri yang paling berhubungan adalah pengalaman bertani sehingga anak petani yang memiliki pengalaman bertani yang tinggi dominan memiliki persepsi yang baik dan minat yang tinggi dalam memandang sektor pertanian., The agricultural sector is an important sector for the continuity of life of the country's people, especially horticultural agriculture. However, there are problems, namely the increasing average age of farmers and the decreasing interest of the younger generation in the world of agriculture. This research looks at the self-characteristics of farmers' children as factors that relate to farmers' children's interests and decisions to contribute to the agricultural sector. The aim of this research is to see the influence of individual characteristics and external factors on aspects of cognition, communication and affection as work interests. The method used in this research is a quantitative method with a questionnaire instrument and supported by qualitative data through in-depth interviews and observations. The results of this research are that there is a relationship between the personal characteristics, perceptions and interests of farmer children. The personal characteristic that is most related is farming experience so that farmer children who have a lot of farming experience predominantly have good perceptions and high interest in looking at the agricultural sector.

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.
