“…In addition to the process of absorbing water hyacinth, the process of reducing ammonia levels was also assisted by the decomposition of organic matter by microorganisms. This causes the organic matter dissolved in the tofu liquid waste to decrease [9]. The results showed that the phytoremediation of water hyacinth by sedimentation was able to make ammonia levels in liquid waste down.…”

Waste from the tofu industry produced the pollutant like NH3, NO2, NO3 with high content that caused environmental pollution. Hence, the processing of tofu liquid waste was needed. The purpose of this research was to determine the effect on the levels of pH, NH3, NO2, NO3 and to determine the biomass of water hyacinth. This research was an experimental research with three research namely tofu liquid waste 100% (control), sedimentation process and the phytoremediation of water hyacinth with 9 duplicates. Parameters measured include pH, NH3, NO2, NO3, and biomass. The Data were analyzed using the one-way ANAVA then continued with Duncan Test at 5% level and analogous to the quality standard of East Java Governor Decree Number 45 of 2002. The results showed that the phytoremediation of water hyacinth by sedimentation was able to increase pH levels from 4.21 to 7.37; reduce NH3 levels from 6.41 to 1.83; decrease NO2 levels from 1.94 to 0.61; decrease NO3 levels from 15.91 to 12.66; and increase the biomass of water hyacinth.The Phytoremediation of water hyacinth (Eichornia crassipes) by sedimentation can be used to improve the quality of liquid waste in accordance to the standard of quality for the parameters of pH, NO2 and NO3, NH3.

“…Sedangkan limbah cair, sebagian besar dialirkan langsung air limbahnya ke saluran-saluran pembuangan, sungai ataupun badan air penerima lainnya tanpa diolah terlebih dahulu. Bahan organik yang terdapat pada limbah cair industri tahu apabila berada dalam konsentrasi tinggi, maka akan menimbulkan pencemaran pada lingkungan perairan (Irmanto dan Suyata, 2009) Peraturan Pemerintah RI No.28 Tahun 2011 menyebutkan "pencemaran air adalah masuknya atau dimasukkannnya makhluk hidup, zat, energi dan atau berubahnya tatanan air oleh kegiatan manusia sehingga kualitas air turun sampai ke tingkat tertentu yang menyebabkan air tidak dapat berfungsi sesuai peruntukannya".…”

Air limbah industri tahu berpotensi mencemari lingkungan, maka sebelumnya perlu dilakukan pengolahan sebelum dibuang ke lingkungan. Dimana salah satu upaya awal untuk menangani hal tersebut dengan melakukan penelitian. Penelitian ini bertujuan untuk mengidentifikasi cemaran air limbah industri tahu terutama di Kecamatan Nanggalo Kota Padang. Metoda penelitian dilakukan dengan mengambil sampel air limbah industri tahu pada dua lokasi dan dua titik pengambilan sampel untuk masing-masing lokasi, yaitu didekat tempat pembuangan air limbah dan yang berdekatan dengan tempat tinggal masyarakat. Parameter pengujiannya meliputi : BOD, COD, pH, TSS, N-NH3, dan N-Total. Hasil pengujian pada lokasi pertama dan titik pertama, nilai parameter secara berurutan dari BOD, COD, pH, TSS, N-NH3 dan N-Total adalah 226 mg/L; 387 mg/L; 5,10; 156 mg/L; 2,20 mg/L dan 2,54 mg/L, sedangkan pada titik kedua nilainya 153 mg/L; 287 mg/L; 5,82; 128 mg/L; 1,17 mg/L dan 2,02 mg/L. Kemudian pada lokasi kedua dan titik pertama nilai nya secara berurutan, yaitu 154 mg/L; 282 mg/L; 4,87; 120 mg/L; 2,06 mg/L dan 2,76 mg/L, sedangkan pada titik kedua nilainya 121 mg/L; 234 mg/L; 5,11; 88 mg/L; 1,24 mg/L dan 1,67 mg/L. Hasil yang didapatkan menunjukkan kondisi air limbah tahu dengan parameter pH pada semua lokasi dan titik melewati batas baku mutu yang diizinkan menurut Permen Lingkungan Hidup No.5 Tahun 2014 tentang Baku Mutu Air Limbah Bagi Usaha dan/atau Kegiatan Pengolahan Kedelai. Tofu industry wastewater has the potential to pollute the environment, so it needs to be trated before it is discharged into the environment. Where is one of the initial efforts to deal with this by conducting research. This study aims to identify tofu industry wastewater contamination, especially in Nanggalo District, Padang City. The research method is carried out by taking tofu industrial wastewater samples at two locations and two sampling points for each location and two sampling points for each location, which are near the waste water disposal site and which is adjacent to the community residence. The testing parameters include : BOD, COD, pH, TSS, N-NH3 and N-Total. The test results at the first location and first point, the parameter values in arrow of BOD, COD, pH, TSS, NH3 and N-Total are 226 mg/L; 387 mg/L; 5,10; 156 mg/L; 2,20 mg/L and 2,54 mg/L, while at the second point the value is 153 mg/L; 287 mg/L; 5,82; 128 mg/L; 1,17 mg/L and 2,02 mg/L. Then at the second location and the first point the values are in sequence, which is 154 mg/L; 282 mg/L; 4,87; 120 mg/L; 2,06 mg/L and 2,76 mg/L, while at the second point the value is 121 mg/L; 234 mg/L; 5,11; 88 mg/L; 1,24 mg/L and 1,67 mg/L. The results obtained indicate the condition of tofu wastewater with pH parameters at all location and the point of exceeding the permitted quality standard according to Environmental Regulation No.5 of 2014 concerning Wastewater Quality Standars for Soybean Business and / or Processing Activities.

“…According to Sugiharto in Irmanto and Suyata (2009), coffee grounds include organic materials that can make into activated carbon for use as adsorbents or absorbent materials. Coffee waste is usually more discarded because it is considered waste, but actually, coffee grounds can utilize as activated carbon that will add value function as an adsorbent to increase the carrying capacity to the environment, especially in the climate of peat swamp land.…”

Peat water has a distinctive dark brown or yellow color, low pH, it tastes sour, high organic matter content, high levels of iron and manganese. One of the ways that can be used to reduce the levels of iron in peat water is doing adsorption process by using activated carbon coffee waste because the coffee waste included organic ingredients. The purpose of this research was to identify the influence of the concentration of activated carbon robusta coffee waste (Coffea robusta Lindl.) against the iron levels in peat water. This research uses the draft Posttest-Only Control Group Design. Manufacture of activated carbon robusta coffee waste (Coffea robusta Lindl.) consists of the processes of dehydration, carbonization, and activation, with the results 25.9% of rendemen, 14.05% water content, a rate of 9.9% ash, and iod absorbance 647.19 mg/g. Activated carbon coffee waste added to 100 ml of peat water as much as 3 gr, 4.5 gr, and 6 gr with the stirring speed 400 rpm for 60 minutes obtained early iron levels of 2.75 mg/L and dropped to 1.19 mg/L, 1.02 mg/L, and 0.95 mg/L. Conclusions This study is there is the influence of the concentration of activated carbon robusta coffee waste (Coffea robusta Lindl.) against the iron level of peat water iron and frequency of 6 gr as a concentration of the best efficiency adsorption of 65.4% because it can reduce the levels of iron in 100 ml of peat water from 2.75 mg/L be 0.95 mg/L. By regulation of the Minister of health RI No. 416/ Menkes/PER/IX/1990 namely of 1.0 mg/L. Suggestions for further research to improve the heating temperature and concentration of the activator to obtain active carbon absorption .
