Abstract

Clove soaking wastewater that is discharged directly into water bodies without being carried out first results in environmental pollution. Researchers made observations for the characteristics of 2 sampling times, with the COD and BOD concentrations for the first sample, respectively, the COD concentration was 5,703.5 ppm and BOD was 2,270.8 ppm. For the second sample, the concentration of COD is 4,181.4 ppm and BOD is 2,020.7 ppm. Therefore, the researchers tried to treat the water from the cloves soaked by coagulation – flocculation processing. The chemical used in the coagulation stage is alum as a coagulant, while at the flocculation stage, polyelectrolyte is used as a flocculant (auxiliary coagulant). The success indicator in this research is the percentage of COD and BOD removal for treated wastewater. This research was conducted in two stages of processing, the first processing using a dose variation of alum, while the second processing using a dose variation of polyelectrolyte. It was found that alum dose added of 3000 ppm resulted in COD removal percentage of 62.6% and BOD of 72.3%, while in the flocculation process the dose of polyelectrolyte (anionic) added 100 ppm and was able to remove COD and BOD by 60% and 32%.Keywords: Coagulation, Flocculation, Alum, Polyelectrolyte

Abstract

Dregs tofu and waste are organic materials that still contain a lot of good nutrition for larva feed.  The research aim to determine waste reductions by larva BSF.  This research uses a plastic box in which a mixture of tofu dregs, vegetable, and fruit are placed in certain composision.  No additional feed was added during this research.  The results shows that the mixture of dregs tofu and fruit (2 produce ECD= 10,2% and WRI = 3,1% higher than others containers/reactors.

Abstract

Lapindo mud waste is hot mud from PT. Lapindo Brantas allegedly contains hazardous materials. Utilization of Lapindo mud waste must be carried out with several tests. Testing on the characteristics of the waste using the Toxicit Characteristic Leadching Procedure (TCLP) test. This research was conducted on a laboratory scale by varying the composition of cement, fine aggregate and Lapindo mud ((1:2:10), (1:3:10), (1:3:9) which were used as bricks and will be tested for absorption. brick brick gravity test, brick surface friction test The results of this study are the average compressive strength of bricks using Lapindo mud with a mixture composition of 10% mud decreased by 18.09 Kg/cm², the composition of the mixture 7.5% mud, namely 18.57 Kg/cm², and 5% mix composition, which is 20.94 Kg/cm², can be categorized as B4 quality bricks (Used for non-weather protected walls), with a standard strength of 21 kg/cm². Meanwhile, the absorption test of all brick compositions meets the requirements SNI is based on SNI 03-0349-1989 regarding concrete bricks (brick), the maximum air absorption rate requirement is 25%.Keywords: Brick, Lapindo Mud, Absorption Test

Abstract

Limbah cair pada umumnya mengandung bahan-bahan atau zat-zat yang dapat membahayakan bagi kesehatan manusia serta mengganggu lingkungan hidup. Salah satu komponen pencemar limbah yang berbahaya adalah adanya pencemar logam berat. Logam Nikel merupakan salah satu cemaran berbahaya jika terdapat dalam air apalagi jika digunakan untuk kegiatan sehari-hari. Sebelum limbah cair dibuang ke badan sungai, harus memenuhi baku mutu yang telah ditetapkan sesuai dengan PERMEN LH No. 3 tahun 2010 tentang Baku Mutu Air Limbah bagi Kawasan Industri. Pada penelitian ini dilakukan analisa logam berat pada limbah industri di suatu kawasan di Industri Karawang baik sebelum maupun setelah proses pengolahan limbah untuk mengetahui tingkat cemaran logam berat Nikel pada limbah cair dan efektifitas pengolahan air limbah di Karawang. Hasil penelitian menunjukan bahwa proses pengolahan limbah tersebut efektif menurunkan kadar Nikel terlarut dari rata-rata 0,016 mg/L sebelum proses olah menjadi 0,006 mg/L setelah melalui proses pengolahan air. Penurunan kadar Nikel terbesar selama penelitian dilakukan mencapai 94 % pada sampel pertama. Kandungan Nikel dalam air baku maupun outlet telah memenuhi standar baku mutu Permen LH No.3 Th.2010 yaitu batas makasimal yaitu 0,5 mg/L
