Abstract

Climate change greatly influences agricultural activities carried out by farmers in Indonesia. Farmers have begun to actively engage in organic farming, which is one of the production methods that is environmentally friendly, so that it can guarantee ecological sustainability. For this reason the study was conducted to determine the extent to which organic farming practices carried out by farmers can have implications for improving soil chemical properties and rice production. The method of this research is carried out by taking soil samples by surveying rice fields that apply organic systems and conventional systems. Data analysis using t test with a confidence level of 95%. The results showed that there were improvements in several soil chemical properties which included: organic C, total N, P available, K-dd and Al-dd soil, but improved soil chemical properties that were not significantly different from soil ph and soil CEC . To improve rice production, rice glucose content, root length, root volume and root dry weight there were significant improvements. Analysis of organic farming practices is important to limit the occurrence of all forms of environmental pollution that may be produced by conventional agricultural activities.

Abstract

Air limpasan dari aktivitas pertambangan batubara sangat berpotensi pada pembentukan air asam tambang. Air asam tambang yang berasal dari mine sump area tambang Air Laya PT. Bukit Asam (Persero), Tbk. mempunyai nilai pH rendah yaitu berkisar dari 3 sampai 5, kondisi ini akan melarutkan unsur-unsur logam seperti Fe dan Mn pada batuan yang dilalui oleh air asam tambang tersebut. Elektrokoagulasi merupakan metode untuk melakukan proses koagulasi dengan menggunakan tegangan listrik searah yang didasarkan pada peristiwa elektrokimia. Penelitian dilakukan dengan sistem batch skala laboratorium yaitu menggunakan volume air asam tambang 1,8 L, elektroda besi (Fe) 8 cm x 11 cm x 0,8 mm sebanyak 3 lempeng sebagai katoda dan elektroda aluminium (Al) 8 cm x 11 cm x 0,8 mm sebanyak 3 lempeng sebagai anoda. Percobaan dilakukan dengan interval waktu 15 menit, 30 menit, 45 menit dan 60 menit, lalu menggunakan tegangan 6 V, 12 V, dan 24 V untuk jarak elektroda yaitu 1,5 cm dan 2 cm. Dengan tetap mempertimbangkan faktor ekonomi maka diketahui waktu, jarak dan tegangan DC yang paling efektif digunakan untuk proses elektrokoagulasi adalah 12 Volt dan 45 menit yang akan menghasilkan persen peningkatan nilai pH = 32,96 ; persen penurunan logam Fe = 94,0111 ; dan persen penurunan logam Mn = 88,2878, akan tetapi faktor jarak antara elektroda tidak berpengaruh pada proses ini.

Abstract

Pencemaran logam berat menjadi issue penting secara global terhadap masalah lingkungan, kese-hatan, ekonomi dan perencanaan. Mengingat Pb tergolong logam berat dengan sifat toksik tinggi, maka untuk menghilang Pb dari tanah perlu dilakukan remediasi secara fitoremediasi. Penelitian ini dilakukan di rumah bayang di kampus Program Pascasarjana, Universitas Sriwijaya. Metode yang digunakan yaitu penambahan logam Pb ke dalam media tanah sebanyak 319,71 mg.kg-1 dengan media tanah sebanyak 5 kg setiap perla-kuan. Setelah 60 hari tanam dilakukan analisa kandungan logam Pb pada media tanah dan tanaman dengan metode analisa AAS yang dilakukan di di laboratorium Jurusan Tanah, Fakultas Pertanian, Universitas Sriwi-jaya. Hasil yang diperoleh dari analisa laboratorium dilakukan perhitungan akumulasi logam Pb dengan faktor biokonsentrasi untuk mengetahui kemampuan tanaman dalam mengakumulasi logam Pb. Hasil penelitian me-nunjukkan bahwa kemampuan tanaman hias dalam menyerap logam Pb berbeda dan tergantung dengan je-nis tanaman. Tanaman Hanjuang (Cordyline fruicosa) mempunyai kemampuan menyerap logam Pb yang lebih tinggi dengan nilai 2,36 mg.kg-1.hari-1, diikuti oleh tanaman Sambang Dara (Excoecaria cochinensis) dengan nilai 1,70 mg.kg-1.hari-1. Tanaman yang paling rendah menyerap logam Pb adalah tanaman Lidah Mertua (Sanseviera trifasciata Prain) dengan nilai konsentrasi logam Pb yaitu 0,65 mg.kg-1.hari-1. Efisiensi penyerapan logam Pb oleh tanaman yang tertingi dimiliki oleh tanaman Hanjuang (Cordyline fruicosa) yaitu 44,28%. Per-tumbuhan tanaman selama 60 hari penelitian juga bervariasi dan tanaman yang memiliki pertumbuhan ter-baik adalah tanaman Hanjuang (Cordyline fruicosa). Dengan demikian, tanaman Hanjuang (Cordyline fruicosa) merupakan tanaman terbaik dalam menyerap logam Pb dalam tanah.

Abstract

Tujuan dari penelitian ini adalah untuk menentukan konsentrasi logam berat (besi) dalam dua spesies ikan konsumsi yaitu ikan Sepat Siam (Trichogaster pectoralis), ikan Betok (Anabas testudineus), beserta air dan sedimen yang diambil dari air kolam limbah pabrik karet di Kelurahan Keramasan, Kecamatan Kertapati, Palembang yang dilakukan pada bulan Maret sampai Juni, 2013. Logam berat ini dianalisa dengan alat AA-7000 Shimadzu, Spektroskopi Serapan Atom (AAS). Konsentrasi logam berat Fe pada ikan Sepat Siam, ikan Betok , air dan sedimen secara berurutan: (2,70 mg/kg ; 2,63 mg/kg ; 1,78 mg/l dan 9353,1 mg/kg). Hasil anali-sa menunjukan bahwa tingkat akumulasi logam Fe melebihi batas baku mutu yang direkomendasikan oleh BPOM RI untuk ikan atau makanan, sehingga ikan yang ada di dalam kolam tersebut tidak layak untuk dikonsumsi manusia. Konsentrasi logam Fe di permukaan air lebih tinggi dari baku mutu yang direkomendasikan oleh pemerintah provinsi Sumatera Selatan, dan berisiko bagi kesehatan manusia. Dibu-tuhkan pengawasan secara terus-menerus terhadap konsentrasi logam berat dalam air permukaan dan ikan di kolam tersebut. Kata kunci : Besi, Toksisitas
