Abstract
Pembangunan pertanian merupakan salah satu pilar dalam meningkatkan kesejahteraan masyarakat. Banyaknya pengalihan fungsi lahan menjadi kawasan industri pertambangan, dimana pembangunan industri tersebut berdampak positif dan juga berdampak negatif bagi pembangunan pertanian, antara lain yaitu jika pembuangan limbah industri tidak melalui pengolahan terlebih dahulu (IPAL), hasil pembuangan limbahnya berpotensi untuk mencemari lingkungan, khususnya terhadap tanah-tanah pertanian, diantaranya adalah logam berat, yang berpotensi terhadap percemaran lingkungan pertanian, yaitu Merkuri (Hg), Timbal (Pb), Kadmium (Cd), Krom (Cr), Tembaga (Cu), Seng (Zn), Kobalt (Co), dan Nikel (Ni).
Lahan-lahan pertanian yang tercemar semakin meluas akibat pembuangan limbah industri. Oleh karena itu, perlu dicari alternatif penanggulangannya melalui penelitian rehabilitasi lahan. Tujuan dilakukannya kajian studi literatur ini adalah untuk mengkaji dampak logam berat akibat limbah industri pada lahan pertanian area pertambangan emas, mengkaji efisiensi tumbuhan dalam menyerap logam berat pada tanah pertanian area pertambangan emas yang tercemar, dan mengkaji studi kasus penerapan fitoremediasi untuk meremediasi lahan pertanian area pertambangan emas yang tercemar. Metode studi yang digunakan adalah dengan menyusun kajian pustaka yang merupakan kumpulan berbagai literatur yang sesuai dengan referensi yang akan dikaji dan berdasarkan studi kasus yang ada. Selain itu dilakukan kajian referensi yang berkaitan dengan fitoremediasi pencemaran logam berat dengan menggunakan tumbuhan hiperakumulator. Studi kasus permasalahan logam berat terjadi pada lahan pertanian kawasan penambangan emas di Gunung Pongkor, Desa Bantar Karet, Kecamatan Nanggung, Kabupaten Bogor.
Penyingkiran polutan logam berat menggunakan metode fitoremediasi dengan mekanisme fitoekstraksi menggunakan tumbuhan hiperakumulator yang mampu mengikat Merkuri (Hg) secara cepat dan tepat. Jenis tumbuhan yang digunakan adalah Kacang Kalopo (Calopogonium mucunoides) pada fitoremediasi in-situ dan ex-situ secara single plant species. Sedangkan tumbuhan yang digunakan untuk fitoremediasi ex-situ secara mixed plants species adalah Kacang Kalopo (Calopogonium mucunoides) dan Rumput Gajah Kate (Pennisetum purpureum CV. Mott). Hasil studi kasus pencemaran logam berat Merkuri (Hg) di kawasan Pertambangan Emas Pongkor menyatakan bahwa fitoremediasi secara in-situ mampu lebih efisien dalam mengikat cemaran Merkuri (Hg) yang ada di lahan tersebut. Presentase keberhasilannya berada diantara 90-100%.

Agricultural development is one of the pillars in improving people's welfare. The number of conversions of land functions into mining industrial areas, where industrial development has a positive and negative impact on agricultural development, among others, is that if industrial waste is not disposed of through pre-treatment (WWTP), the results of the waste disposal have the potential to pollute the environment, especially the soil. - agricultural soil, including heavy metals, which have the potential to pollute the agricultural environment, namely Mercury (Hg), Lead (Pb), Cadmium (Cd), Chromium (Cr), Copper (Cu), Zinc (Zn), Cobalt (Co ), and Nickel (Ni).
Contaminated agricultural land is increasingly widespread due to the disposal of industrial waste. Therefore, it is necessary to find an alternative to overcome it through land rehabilitation research. The purpose of this literature study is to examine the impact of heavy metals due to industrial waste on agricultural land in the gold mining area, to examine the efficiency of plants in absorbing heavy metals in polluted agricultural land in gold mining areas, and to examine case studies of the application of phytoremediation to remediate agricultural land in mining areas. tainted gold. The study method used is by compiling a literature review which is a collection of various literatures in accordance with the references to be studied and based on existing case studies. In addition, reference studies related to phytoremediation of heavy metal pollution were conducted using hyperaccumulator plants. A case study of heavy metal problems occurs in agricultural land in the gold mining area at Mount Pongkor, Bantar Karet Village, Nanggung District, Bogor Regency.
Removal of heavy metal pollutants using the phytoremediation method with a phytoextraction mechanism using hyperaccumulator plants that are able to bind Mercury (Hg) quickly and precisely. The plant species used were Kacang Kalopo (Calopogonium mucunoides) in in-situ and ex-situ phytoremediation as a single plant species. Meanwhile, the plants used for ex-situ phytoremediation with mixed plant species were Kacang Kalopo (Calopogonium mucunoides) and Rumput Gajah Kate (Pennisetum purpureum CV. Mott). The results of a case study of mercury (Hg) heavy metal contamination in the Pongkor Gold Mining area stated that in-situ phytoremediation was more efficient in binding Mercury (Hg) contaminants in the land. The percentage of success is between 90-100%.
