Abstract

Abstrak: Pemenuhan kebutuhan air bersih yang aman dan layak dikonsumsi belum dapat dirasakan oleh semua lapisan masyarakat Lombok Tengah akibat tingginya angka kemiskinan dan rendahnya tingkat pendidikan masyarakat. Selain itu dengan tingginya aktivitas sektor pertanian yang menggunakan pupuk dan pestisida, dimungkinkan bahan kimia dan hasil peruraianya akibat proses  leaching terbawa aliran air kemudian meresap  ke dalam tanah dan masuk ke dalam sumber air tak terlindungi. Hal ini diindikasikan dengan hasil pengukuran kadar nitrit dan ammonia di beberapa sungai yang mengaliri desa. Salah satu solusi yang akan diterapkan dalam kegiatan ini adalah penerapan teknologi tepat guna tentang proses pengelolaan air siap minum dengan membuat unit pengolahan air irigasi menjadi air siap minum dengan menggunakan metode filtrasi-adsorpsi (kombinasi oleh pasir silika, karbon aktif dan membran) dan penyinaran lampu UV untuk desinfikasi. Sosialisasi kepada kelompok – kelompok tani Desa Jago dilakukan sebagai sarana alih teknologi tentang pengolahan air siap minum dan sebagai upaya mengedukasi masyarakat mengenai perilaku hidup bersih dan sehat serta pemanfaatan air secara bijak dan efektif. Keberlanjutan program dilakukan melalui pengelolaan mandiri oleh P3A dengan dukungan dari masyarakat sekitar dan pengawasan dari Perangkat Desa Jago. Kata kunci: air siap minum, filtrasi, adsorpsi, uv radiasi, Desa Jago.

Abstract

Telah dilakukan studi interaksi asam humat dengan larutan urea, super fosfat 36 (sp36), dan kalium klorida (KCl) dengan menggunakan metode spektrofotometri Infra Red (IR). Penggunaan asam humat diketahui dapat meningkatkan ketersediaan, pengambilan nutrien pada tanaman dan efisiensi pemupukan urea, SP36 dan KCl. Akan tetapi, gugus fungsi asam humat yang berperan pada interaksi dengan pupuk belum dikaji. Penelitian dilakukan dengan menginteraksikan asam humat dan larutan pupuk urea, SP36 dan KCl dengan perbandingan massa 1:5. Interaksi asam humat dengan ketiga pupuk diketahui dengan membandingkan spektra IR asam humat murni dengan asam humat setelah bereaksi dengan ketiga pupuk. Adanya pergeseran serapan bilangan gelombang mengindikasikan terjadi interaksi. Pengaruh penambahan asam humat pada efisiensi pemupukan dilakukan dengan menghitung kadar nitrogen, fosfor dan kalium pada sampel tanaman jagung menggunakan metode Kjehdahl dan spektrofotometri UV-Vis. Hasil karakterisasi dengan spektrofotometer Fourier Transform Infra Red (FTIR) menunjukkan bahwa struktur hipotetik asam humat memiliki gugus fungsional –OH, alifatis, eter, aromatis dan karboksilat. Interaksi asam humat dengan ketiga pupuk terjadi pada gugus fenol, aromatis dan karboksilat yang ditunjukkan dengan adanya pergeseran serapan pada daerah 3421 cm-1,  1611 cm-1dan 1375 cm-1. Penambahan asam humat pada pemupukan dasar dapat meningkatkan efisiensi pemupukan.
