摘要

在占碑省美兰因县,人们开采黄金(通常称为无证开采黄金(PETI))的现象是一个严重的问题,因为它发生在高产水稻田里。这种活动会在开采过程中对稻田造成破坏。采矿活动结束后,受损的稻田需要处理,特别是要重新开垦成稻田。这项研究在占碑省美兰因县彭卡兰詹布区的巴鲁彭卡兰詹布村进行。研究于 2022 年 5 月至 11 月进行,包括两个阶段,即1)绘制前矿区土地成为稻田的潜力图;2).分析已开垦稻田的土壤特性。根据 PPT Bogor(1994 年)的土壤物理和化学特性标准,对数据进行了描述性分析。结果表明,旧矿区复垦水稻田的土壤物理特性是容重相对较低、土壤质地较粗(沙壤土)。土壤的化学性质表明,这块土地的有机碳和全氮含量很低,土壤 pH 值相对偏酸或微酸。研究表明,随着开垦后利用时间的延长,该土壤的质量也呈上升趋势:稻田、土地开垦、擅自采矿、土地质量

KAJIAN POTENSI DAN KARAKTERISTIK TANAH BEKAS PENAMBANGAN SEBAGAI LAHAN SAWAH DI KECAMATAN PANGKALAN JAMBU KABUPATEN MERANGIN PROVINSI JAMBI
The phenomenon of people's gold mining or often called gold mining without permit (PETI) in Merangin Regency, Jambi Province is a serious problem because it occurs in productive paddy fields. This activity causes damage to paddy fields due to processes during mining activities. After the mining activity, the damaged paddy fields needed handling, especially for being reclaimed into paddy fields again. The research was conducted at the Baru Pangkalan Jambu Village, Pangkalan Jambu District, Merangin Regency, Jambi Province. The research took place from May to November 2022 which consisted of two stages, namely: 1) mapping the potential of ex-mining land to become rice fields, 2). Analysis of soil characteristics in paddy fields that have been reclaimed. Data were analyzed descriptively based on the criteria of soil physical and chemical properties based on PPT Bogor (1994). The results showed that the soil physical properties of paddy rice fields from reclamation of former mines had relatively low bulk density, coarse soil texture (sandy loam). The chemical properties of the soil indicate that the land has very low organic C and total nitrogen and a relatively acidic to slightly acidic soil pH. Research shows that the quality of this soil tends to increase with the duration of post-reclamation utilization.Keywords: Paddy field, land reclamation, unauthorized people's mining, land quality
