Abstract

Harga pupuk kimia yang mahal serta serangan hama keong mas menjadi salah faktor penyebab menurunnya produktivitas padi di Kecamatan Kotanopan. Pengkajian ini bertujuan untuk mengetahui tingkat persepsi petani dan faktor-faktor yang mempengaruhi persepsi petani dalam pemanfaatan keong mas (P.canaliculata L.) Menjadi pupuk organik cair di Kecamatan Kotanopan. Pengkajian ini menggunakan metode deskriftif kuantitatif dengan menggunakan 57 orang sebagai responden. Metode pengumpulan dataya menggunakan observasi dan kuesioner. Analisis data menggunakan skala likert dan pengolahan data menggunakan analisis regresi linear berganda. Hasil pengkajian ini menunjukkan bahwa tingkat persepsi petani dalam pemanfaatan keong mas (P. canaliculata L.) menjadi pupuk organik cair pada padi sawah di Kecamatan Kotanopan tergolong tinggi dengan persentase sebesar 63,21%. Secara simultan umur, pendidikan, pengalaman bertani, luas lahan, peran penyuluh, akses informasi, intensitas penyuluhan dan ketersediaan pupuk kimia berpengaruh secara simultan terhadap persepsi petani dalam pemanfaatan keong mas menjadi pupuk organik cair pada padi sawah di Kecamatan Kotanopan. Secara parsial umur, pendidikan, luas lahan dan ketersediaan pupuk kimia berpengaruh terhadap persepsi petani dalam pemanfaatan keong mas (P. canaliculata L.) menjadi pupuk organik cair sedangkan pengalaman bertani, peran penyuluh, akses informasi dan intensitas penyuluhan tidak berpengaruh terhadap persepsi petani dalam pemanfaatan keong mas (P.canaliculata L.) menjadi pupuk organik cair pada padi sawah di Kecamatan Kotanopan.

Abstract

Category theory is one of the important frameworks in modern mathematics because it is able to unify various algebraic concepts and structures. In addition, this theory has been widely applied in many other fields. This article aims to provide a comprehensive discussion of the role of category theory as a universal language that not only explains relationships among mathematical objects, but also serves as a methodological foundation for computer science, logic, and data science. This study employs a qualitative approach through a literature review by examining key concepts such as objects, morphisms, functors, adjunctions, and monads, as well as their roles in bridging abstract theory and practical applications. The results of the literature review indicate that category theory is capable of simplifying the complexity of algebraic structures through a higher level of abstraction. Through this approach, different branches of mathematics that were previously fragmented can be interconnected. Furthermore, category theory has been widely used in functional programming, the development of logic-based systems, and data flow modeling, making it highly relevant in the digital era. The research approach involves literature review, content analysis, and triangulation to ensure data validity, with the implication that category theory can enrich teaching and research in the field of algebra.
