Pada zaman teknologi sekarang Dalam Akademisi pendidikan diartikan sebagai salah satu usaha sadar dan terencana untuk mewujudkan suasana belajar dan proses pembelajaran agar peserta didik secara aktif mengembangkan potensi dirinya untuk memiliki kekuatan spiritual keagamaan, pengendalian diri, kepribadian, kecerdasan, akhlak mulia, serta keterampilan yang diperlukan dirinya, masyarakat, bangsa dan Negara (Sisdiknas, 2003: pasal 1).Pengertian dari Pendidikan  merupakan suatu  proses pembelajaran, yaitu suatu  usaha yang dilakukan seseorang untuk memperoleh  perubahan tingkah laku yang baru secara keseluruhan, sebagai hasil pengalamannya sendiri dalam interaksi dengan lingkungannya. Proses pembelajaran  dipengaruhi oleh beberapa faktor, yaitu lingkungan keluarga, seperti cara orang tua mendidik anak, keharmonisan hubungan antara anggota keluarga, dan ekonomi akan berdampak terhadap cara belajar. Cara keluarga  memahami konsep pendidikan akan berbeda prosesnya pada siswa yang keluarganya tidak  memahami tentang perlunya pendidikan bagi anaknya pada masa sekarang dan masa yang akan datang. Faktor yang kedua adalah lingkungan sekolah, seperti metode, kurikulum, relasi guru dan siswa, siswa dan siswa, sarana dan prasarana. Faktor yang ketiga adalah lingkungan masyarakat, siswa lebih banyak menggunakan waktunya di lingkungan masyarakat setelah mereka belajar di sekolah. Kehidupan di lingkungan masyarakat turut pula mempengaruhi cara dan proses pembelajaran pada diri siswa, seperti kegiatan, teman bergaul, dan mas media. Ketiga faktor lingkungan tersebut turut pula mempengaruhi proses pembelajaran pada diri siswa. Selain lingkungan, faktor  internal siswa juga mempengaruhi proses pembelajaran, seperti kecerdasan, motivasi, kepribadian, dan kesempatan

Sektor pertanian memainkan peran penting dalam mendukung perekonomian daerah, khususnya dalam penyediaan bahan pangan, menciptakan lapangan kerja, serta menurunkan tingkat kemiskinan. Namun, menentukan sektor pertanian unggulan sering menjadi kendala karena kurangnya analisis yang komprehensif dan data yang memadai. Penelitian ini bertujuan untuk merancang Sistem Pendukung Keputusan (SPK) dengan memanfaatkan metode Multi-Objective Optimization by Ratio Analysis (MOORA) guna memilih usaha sektor pertanian unggulan di suatu wilayah. Metode MOORA dipilih karena keunggulannya dalam mengelola banyak kriteria secara efisien dan sederhana. Penelitian ini melibatkan tujuh kriteria utama, yaitu kesesuaian wilayah, jenis komoditas unggulan, tingkat produktivitas, luas lahan, pola musiman atau tahunan, kebutuhan tenaga kerja, dan sumber pendanaan. Hasil penelitian menunjukkan bahwa alternatif terbaik adalah usaha Tanaman Pangan dengan nilai Yi tertinggi sebesar 0.5104 di ikuti oleh Holtikultura dan Perkebunan. Walaupun terdapat kesamaan antara data yang digunakan dengan peringkat yang dihasilkan, validitas hasil penelitian ini telah dianalisis kembali melalui uji korelasi Spearman. Hasil analisis menunjukkan nilai korelasi sebesar 0,300, yang mengindikasikan bahwa hubungan antara kedua variabel yang dibandingkan tergolong lemah. Rendahnya hubungan ini menunjukkan perlunya peningkatan kualitas data serta pengintegrasian informasi mengenai jumlah usaha agar sistem peringkat dapat lebih efektif dan relevan dalam mendukung pengembangan sektor pertanian.
