Abstract

Setiap individu mempunyai persepsi yang berbeda pada suatu stimulus yang mereka terima, meskipun stimulus itu sama akan tetapi hasil persepsinya akan berbeda. Adanya suatu kebudayaan, lingkungan sosial, serta kepercayaan akan memberikan arti terhadap objek yang dimaknai individu, dan akhirnya individu akan berperan dalam menentukan jawaban yang berupa sikap dan tingkah laku individu terhadap objek yang dipersepsi. Di Indonesia belakangan ini fenomena yang sering terjadi tentang seksualitas pada kalangan remaja, seakan-akan seks pranikah sudah menjadi suatu hal yang wajar dalam menyalurkan ungkapan kasih dan sayang (berpacaran). Adapun jenis pendidikan Sekolah Menengah Atas yang ada di Indonesia ialah Lembaga Pendidikan Umum atau dikenal dengan SMA dan Lembaga Pendidikan Agama atau MA. Tujuan penelitian ini adalah untuk mengetahui perbedaan persepsi tentang perilaku seksual pranikah antara siswa pada Lembaga Pendidikan Umum (SMA) dengan siswa pada Lembaga Pendidikan Agama (MA) di SMA dan MA Ma’arif Sukorejo.

Abstract

Saluran udara tegangan ekstra tinggi (SUTET), peralatan elektronik seperti microwave oven dan alat komunikasi seperti handphone merupakan sumber-sumber yang dapat menghasilkan radiasi gelombang elektromagnetik. Penggunaan perangkat elektronik yang jumlahnya semakin meningkat dapat mengakibatkan peningkatan gelombang elektromagnetik dalam bentuk radisasi gelombang mikro yang teradiasi ke lingkungan. Radiasi gelombang mikro tersebut dapat mengganggu kesehatan manusia, seperti meningkatnya detak jantung, timbul rasa gelisah dan tidak fokus. Selain itu, radiasi dari transmisi listrik tegangan tinggi dapat memicu seseorang mengidap leukemia, limfoma, infertilitas pada pria, serta neurosis atau gangguan saraf pada manusia. Berdasarkan permasalahan tersebut, dibutuhkan material yang mampu meredam atau menyerap gelombang mikro agar tidak berbahaya bagi manusia. Pasir besi merupakan sumberdaya alam yang memiliki potensi menjadi bahan industri bernilai tinggi apabila diolah berdasarkan sifatsifat kemagnetannya. Sebuah material penyerap gelombang mikro neodimium barium ferit dengan komposisi kimia 0,8BaO : 0,2Nd2O3 : 6Fe2O3 berbahan dasar pasir besi Binangun, Cilacap dibuat menggunakan metode solid state reaction. Material ini dikarakterisasi menggunakan XRD, VSM, dan VNA. Hasil karakterisasi menunjukkan bahwa material neodimium barium ferit sudah tepat dijadikan sebagai material penyerap gelombang mikro. Hasil reflection loss microwave mencapai 25 dB, material tersebut sangat bagus untuk melakukan penyerapan gelombang mikro. Bahkan dapat juga digunakan sebagai material anti-radar. Tahap realisasi ke depan, material ini dapat dijadikan campuran pada cat tembok guna menyerap gelombang mikro yang ada di lingkungan sehingga dapat bermanfaat bagi masyarakat umum.
