Abstract

Teknik pertanian konservasi yang diterapkan di Desa Rembitan Kabupaten Lombok Tengah bertujuan meningkatkan hasil pertanian pada skala usaha tani dengan meminimalisasi biaya pengolahan tetapi memaksimalkan produksi, disamping itu juga sebagai dasar menuju pertanian lestari, berkelanjutan dan memperbaiki mata pencaharian. Ada tiga prinsip dasar pertanian konservasi yakni: 1) Mengolah tanah seringan-ringannnya hingga tidak diolah sama sekali; 2) Menutup permukaan tanah serapat-rapatnya secara terus-menerus sepanjang tahun; 3) Tumpang sari dan rotasi tanaman. Penerapan teknik konservasi merupakan kolaborasi kegiatan budidaya tanaman serta melakukan pembenahan tanah yang rusak/kritis, mengamankan dan memelihara produktivitas tanah agar tercapainya produksi tinggi dalam waktu yang tidak terbatas, dan meningkatkan produktivitas lahan usahatani. Untuk dapat mewujudkan ketiga hal tersebut makan dilakukan beberapa metode penerapan teknik konservasi pada lahan tegalan, yakni: 1) Teknik Konservasi Vegetatif; 2) Teknik Konservasi Mekanik; dan 3) Tanpa Pengolahan Tanah. Ketiga teknik konservasi yang diterapkan pada lahan tegalan ini mampu menjaga permukaan tanah dari erosi dan aliran permukaan (run off) yang tinggi karena adanya mulsa atau vegetasi penutup tanah (cover crop), selain itu teknik konservasi ini juga dapat memelihara bahkan menstabilkan kesuburan pada tanah tegalan seperti yang ada di Desa Rembitan dalam mewujudkan produksi yang maksimal pada skala usaha tani.

Abstract

People's gold mining in Sekotong, also known as Unlicensed Gold Mining (PETI), causes environmental pollution problems because located at the surrounding community processes gold using the amlagamation technique with the help of mercury (Hg) in binding gold. Mercury waste discharged directly into the environment could have adversely affects public health and degrades soil and water quality. The presence of mercury in the soil is strongly influenced by soil characteristics, one of which is soil physical properties. The purpose of this study was to determine the relationship between the physical characteristic ustifluvents Entisol soil of Sekotong soil and mercury content at 0-20 cm soil depth. This research was conducted using descriptive method with survey technique. Soil sampling was conducted at 3 location points near the logs and tailling at a depth of 0 - 10 cm and 10-20 cm, each location point was replicated 3 times. The selection of soil sample points was based on contour differences that affect the proportion of mercury content at each soil depth. The results showed that the highest mercury content was at point 3 with an average value of 0.3089 ppm and there was a strong to very strong relationship between soil physical properties and Hg content.
