Abstract

Permasalahan dan isu strategis daerah pada bidang energi dan sumber daya mineral yang mempengaruhi kerusakan lingkungan hidup berdasarkan pada Rancangan Primer RPJMD 2018-2028 Kabupaten Kuningan  yaitu kegiatan penambangan pasir ilegal dan perubahan lahan. Salah satu lokasi pertambangan di Kabupaten Kuningan berada di Desa Luragung Landeuh. Penelitian ini dilakukan untuk mengetahui proses  kegiatan  pertambangan pasir;  serta mengetahui dampak negatif pertambangan pasir terhadap kualitas lingkungan. Penelitian ini menggunakan metode analisis deskriptif kualitatif. Kesimpulan penelitian ini adalah proses  kegiatan  pertambangan  pasir PT. Anggun Jaya Mandiri di  Desa  Lurangung  Landeuh Kecamatan Luragung Kabupaten Kuningan terdiri dari tahap pra-kontruksi, kontruksi, operasi, produksi, dan rencana pasca tambang. Dampak negatif kegiatan pertambangan pasir terhadap lingkungan adalah kebisingan, debu yang bertebaran, kerusakan infrastruktur jalan; Dampak positif kegiatan pertambangan pasir PT.AJM memberikan peningkatan peluang kerja, memperbaiki fasilitas desa, serta meningkatkan kas Desa Luragung Landeuh. Pandemi Covid-19 pada awal tahun 2020 telah mempengaruhi dalam penyelesaian konflik antara masyarakat dan pihak perusahaan pertambangan.ABSTRACTRegional strategic problems and issues in the field of energy and mineral resources that affect environmental damage based on the Primary Draft RPJMD 2018-2028 Kuningan Regency, namely illegal sand mining activities and land changes.

This research was conducted to determine the process of sand mining activities; as well as knowing the negative impact of sand mining on environmental quality. This study uses a qualitative descriptive analysis method. The conclusions of this study are: (1) The process of sand mining activities of PT. Anggun Jaya Mandiri in Lurangung Landeuh Village, Luragung District, Kuningan Regency consists of pre-construction, construction, operation, production, and post-mining planning stages. The negative impacts of sand mining activities on the environment are noise, scattered dust, damage to road infrastructure; (2) The positive impact of PT.AJM's sand mining activities provides increased job opportunities, improves village facilities, and increases the cash flow of Luragung Landeuh Village. The Covid-19 pandemic at the beginning of 2020 has affected the resolution of conflicts between the community and the mining company.

Abstract

Cadmium (Cd) is a heavy metal that is toxic to humans. Cadmium will bind to metalotionin in the liver to form Cd+MT bonds, which triggers the formation of free radicals and causes oxidative stress. Oxidative stress characterized by elevating of MDA and decreasing of antioxidant enzyme such as SOD. Gotu kola(Centella asiatica) contains active compounds medecassoside that can function to chelate Cd, decreasing MDA  level caused by Cd-Mt bounded and generate SOD level.The aim of this study is to know the effect of Pegagan as natural chelator for Cd poisoning and as antioxidant. Twenty four rats were used in this research and divided into six groups with four replications. Group 1 (C1) as healthy. Group 2 (C2) was only given 14 mg/200 gBW of CdSO4 for 35 days. Group 3, 4, 5 and 6 were given CdSO4 14 mg / 200kgBB and gotu kola extract dose of 20 mg/200gBB, 40 mg/200gBB, 60 mg/200gBB, 80 mg / 200gBB, for 21 days. The parameters studied were blood MDA and SOD level. Measuring parameters were done on the 36th day after administration of  Centella extract. Data were analyzed by Anova and followed by Duncan test The results showed   that Centella all doses can reduce MDA level and increase SOD level. A dose of 40mg / 200gBB Centella extract has been effective in reducing MDA level  as well as increasing SOD level. It can be concluded that dose of  40mg/200gBB can use as a natural chelator of Cd and as antioxidant for Cd poisoning.
