Analisis Lingkungan Sekitar Tambang Nikel Terhadap Kualitas Ternak Sapi Pedaging di Kabupaten Halamahera Timur

Abstract

Continuous activity in nickel mining has resulted in steadily growing numbers of contaminants which influence the environment. Cattle rising nickel mining in East Halmahera are exposed to high contamination. This study was conducted to assess the presence of heavy metal contamination on soil, water, grass and animal products such as liver and meet. The method used were survey and case study. The parameters measured were the heavy metal content (Pb), Cadmium (Cd), Arsenic (As) and Mercury (Hg) in soil, water, grass and sample of cattle liver and meat. The samples were analyzed using AAS (Atomic Absorption Spectrophotometry) method. Thedata obtained were analyzed descriptively and t-test was used to asses the difference results of all parameters measured from two locations. The results showed that Pb in water and outside mining location were 0.1367 and 0.0770 ppm, respectively. Hg concentration in soil, water, grass, liver and meet callte raised around mining location were 17.8725, 0.0447, 6.6925, 7.4910 and 4.7210 ppb, respectively. The water around mining was contaminated with Pb. The contaminanion of Hg on soil, water and grass around mining areas, and also the liver and meat samples of cattle were exceeded the maximum standard that could be tolerated.

Kontaminasi logam nikel (Ni) pada struktur jaringan ikan

“…Industri pertambangan nikel (Ni) dilaporkan berasosiasi dengan logam berat lainnya seperti tembaga (Cu), arsenik (As), besi (Fe), platina (Pt), merkuri (Hg), seng (Zn), kadmium (Cd), timbal (Pb), (Asiah dan Prajanti, 2014; Gunawan et al, 2015;Sarianto dkk., 2016).…”

“…Dampak pertambangan nikel ini juga menyebabkan menurunnya sumberdaya ikan teri dan cumi-cumi di Halmahera Timur (Sarianto et al, 2016). Selain itu, dampak rusaknya tailing pertambangan nikel di Subaim Halmahera Timur menyebabkan konsentrasi logam berat timbal dan merkuri di air, tanah, dan rumput melebihi ambang batas baku mutu (Gunawan et al, 2015).…”

Respon tanaman kedelai (Glycine max L. Merill) pada berbagai konsentrasi cemaran ion logam Ni2+ dengan pemberian biokompos

“…Lahan pertanian yang tercemar oleh limbah industri menyebabkan terjadi penurunan pH tanah yaitu kisaran 4,3 -5,5, tingginya kandungan Al 3+ , kandungan bahan organik rendah, ketersediaan hara N, P, K, Ca dan Mg rendah, serta kemampuan tanah mengikat air rendah (Budhi dan Aminah, 2010). Limbah cair tersebut secara tidak langsung akan masuk ke dalam badan air, sehingga apabila penggunaan air sungai tersebut menyebabkan akumulasi logam berat dalam tanah yang dan bersifat racun bagi tanaman (Gunawan et al., 2015).…”

Improving students’ environmental care character through Positive Character Camp (PCC) program

“…It causes a quality decrease in the environment, which also caused by human error (Vonny, 2017;Zulfa et al 2015). The anthropocentric paradigm is one of the paradigms that plays a significant role in environmental damage (Grey, 1993;Gunawan et al 2015;Kopnina et al 2018;Muda, 2016;Yuono, 2019). It exploited the environment as much as possible without considering sustainability (Dharmika, 2014).…”
