The objectives of this research to determine the combination of the process of precipitation and adsorption in reducing the content of pollutant metals in the hazardous waste category B3 (hazardous toxic substances) produced at the Polinela Analysis Laboratory. The study was conducted in May to November 2019. The results obtained from 3 (three) times of sampling in May 2019 obtained a description of the characteristics of heavy metal content in wastewater in the form of Aluminum (Al) an average of 1.59 ppm, iron content ( Fe) an average of 9.73 ppm and Cadmium (Cd) an average of 0.022 ppm. From these results it can be seen that the wastewater containing Al and Fe has passed the threshold quality standard of waste water that is allowed to be discharged into water resource (PP No.82 of 2001), while the Cd content is still below the threshold. Furthermore, through the precipitation process with Ca (OH)2 0.8 M and adsorption using activated charcoal with contact time of 3 (three) hours the content of pollutants in wastewater can be reduced to 0.92 ppm for Al metals and 0.1 ppm for metals Fe, so that it is below the standard quality of waste water that is allowed to drain in water. Keywords: adsorption, precipitation, quality standard

Abstract Alue Naga waters are a coastal area in Banda Aceh city which is thought to have been exploited due to various human activities. The existence human settlements, tourist spots, fishponds, ports, and places for catching marine biota such as oysters, green mussels and fish are some instances to name a few.This research was conducted in July 2020 using simple random sampling method. Samples of green mussels were taken from a container for cultivation and from the bottom of the stream. Sample analysis was done using Atomic Absorption Spectrophotometer (AAS) at the laboratory of Office for Research and Standardization of Aceh Industries. The heavy metals that were analyzed are Lead (Pb) and Cadmium (Cd). The results showed that the content of Pb found in the cultivated green mussels was <0.0001 mg/Kg and Cd with <0.0002 mg/Kg. The metal content of green mussels found at the bottom of the stream was <0.0004 mg/Kg for cadmium and <0.0001 mg/Kg for lead. The intensity of heavy metal content in the seawater atcultivation locations also did not exceed the quality standard for the stream and aquatic biota with <0.0001 mg/L (Pb) and <0.0004 mg/L (Cd). Therefore, it is safe for human consumption.

Kebutuhan bahan pangan sangat tergantung pada ketersediaanya di lingungan. Bahan pangan yang diperlukan untuk memenuhi kebutuhan sehari-hari harus sehat dan bebas dari bahan pencemar, termasuk logam berat. Ikan kakap putih (Lates calcarifer) sering dijumpai pada kawasan muara sungai di hampir seluruh wilayah Indonesia, bahkan di Papua. Tujuan penelitian ini adalah untuk mengkaji kandungan logam berat Pb, Cd, Cu, Fe, As, dan Hg pada ikan kakap putih (L. calcarifer) yang hidup di perairan estuari Mimika Papua. Perairan estuari di Mimika diketahui sebagai salah satu daerah pengendapan pasir sisa tambang (tailing). Metode yang digunakan adalah survei dan analisis laboratorium kandungan logam berat pada tubuh ikan. Analisis Pb, Cd, Cu, Fe, As, dan Hg ditentukan dengan spektroskopi serapan atom (AAS, Atomic Absorpsion Spectroscopy). Penentuan tingkat pencemaran logam berat dilakukan dengan Metode Standar APHA 3113 Cetac Technologies SPR IDA. Analisis data dilakukan dengan membandingkan kandungan logam berat dalam air dengan baku mutu air laut menurut SK MNLH No. 51 tahun 2004. Untuk kandungan logam berat pada organ tubuh ikan dibandingkan dengan kandungan maksimum logam berat berdasarkan SNI 7387: 2009 tentang batas maksimum cemaran logam berat bahan pangan. Kandungan logam berat pada ikan kakap putih masih tergolong aman dikonsumsi karena mengandung logam berat di bawah ambang batas baku mutu. Kondisi ini didukung oleh hasil analisis logam berat pada air yang menunjukkan masih dalam kondisi baik.   Kata kunci: L. calcarifer, logam berat, Sungai Kamora, Sungai Ajkwa, Mimika.   The need for food depends on the availability in the environment. Foods needed to meet daily needs should be healthy and free of pollutants, including heavy metals. White snapper (Lates calcarifer) is often found in the estuary of the river in almost all parts of Indonesia, even in Papua. The purpose of this research is to study the heavy metal content of Pb, Cd, Cu, Fe, As, and Hg on white snapper (L. calcarifer) which live in Mimika Papua estuary waters. The estuary waters of Mimika are known as one of the deposition areas of tailings sand. The method used is survey and laboratory analysis of heavy metal content in fish body. Analysis of Pb, Cd, Cu, Fe, and Hg was determined by Atomic Absorption Spectroscopy (AAS). Determination of the level of heavy metal contamination was done by Standard Method of APHA 3113 Cetac Technologies SPR IDA.

The scarcity of water and increasing water pollution are the pressing challenge human being facing. Recovering water and valuable heavy metals is highly desired for treating heavy metal containing wastewater. We proposed a novel hydrate-based process to treat Ni2+ containing wastewater. The water recovery, Ni2+ enrichment factor, desalination efficiency were studied using this cyclopentane hydrate-based method. A water recovery of 43% can be obtained with a desalination efficiency of round 88% and an enrichment factor of 1.6. The desalination efficiency and the quality of the as-made water via the hydrate-based process can be further improved to above 99% via three-stage hydrate reaction. The proposed hydrate-based water treatment process may find wide applications in waste water treatment and heavy metal recycling.

SummaryHeavy metal in waste water potentiallycauses environmental pollution. Generally,heavy metal pollutions come from metalplating, textile, latex-rubber goods, and otherindustries. The process of latex-rubber goodindustries uses heavy metal in the form ofZnO as accelerator for rubber vulcanizationprocess, so that Zn 2+ ion exists in wastewatereffluents in concentration as much as 300 ppm,whereas the maximum limit allowed is 2.5 ppm.The chemical way generally used to decreaseZn 2+ concentration in wastewater effluents isby adding bases, NaOH or Ca(OH) 2 until pHreached 11, hence this metal is precipitated asits hydroxide. However, the way is done, isvery high cost and has a risk of the emergencesecondary pollution caused by excess base. Analternative way to absorb Zn 2+ consideredinexpensive is by using biosorbent in the formof Saccharomyces cerevisiae biomass frombioethanol industrial waste. The research wasconducted using artificial wastewater withZn 2+ ion concentration of 300 ppm and the pHwas adjusted to the range between 3-7.Biosorption was conducted by addition of freeS. cerevisiae biomass as well as byimmobilized cells on filter paper. Observationwas carried out for Zn 2+ concentration aftercontact time of two and five hours. The resultsof the research indicated that free andimmobilized S. cerevisiae biomass couldabsorb Zn 2+ metal and decreased itsconcentration from 250-300 ppm to 20-50 ppm.The optimum contact time was reached at onehour, while optimum sorption process occurredat pH 5. At low concentration, less than20 ppm S. cerevisiae biomass absorbed lessZn 2+ The NaOH-treated biomass showed bettersorption capabilities compared to cells treatedby formaldehyde or heat treatments. Thecontinue experiment showed the high capacityof biomass treated with NaOH to absorb Zn 2+ ,until concentration 24,02- 47,95 ppm in thefirst sampling and 1,15-10,99 ppm in thesecond sampling. Combination adsorptionprocess using charcoal and zeolite couldadsorp remain concentration of Zn 2+ , so thatcould reached the limit concentration-allowed.RingkasanLogam berat di dalam air limbahmerupakan penyebab pencemaran lingkunganyang potensial. Pencemaran logam berat padaumumnya berasal dari industri penyepuhanlogam, tekstil, barang jadi lateks, serta industrilain. Pada proses industri barang jadi lateksdigunakan logam berat dalam bentuk ZnOsebagai akselerator proses vulkanisasi karet,sehingga ion Zn 2+ terbawa dalam air limbahindustri barang jadi dengan konsentrasimencapai 300 ppm, sedangkan ambang bataskonsentrasi yang diperbolehkan maksimaladalah 2,5 ppm. Cara kimia yang umum di-gunakan untuk menurunkan kandunganZn 2+ dalam air limbah adalah dengan caramenambahkan basa, umumnya NaOH atauCa(OH) 2 , sampai pH sekitar 11, sehinggalogam berat ini diendapkan sebagai hidroksida-nya. Namun demikian, cara ini sangat mahaldan beresiko munculnya pencemaran sekunderakibat kelebihan basa. Salah satu alternatifyang murah untuk penyerapan Zn 2+ adalahmenggunakan biosorben berupa biomassaSaccharomyces cerevisiae yang berasal darilimbah pabrik bioetanol.Penelitian dilakukan dengan mengguna-kan air limbah artifisial yang mengandung ionZn 2+ dengan konsentrasi 300 ppm. Limbahartifisial diatur pHnya antara 3-7. Biosorpsidilakukan dengan menambahkan biomassaS. cerevisiae bebas maupun yang diamobilisasidengan kertas saring. Pengamatan dilakukanterhadap kandungan Zn 2+ setelah waktu kontakdua dan lima jam. Hasil penelitian menunjuk-kan bahwa biomassa S. cerevisiae bebasmaupun amobil mampu menyerap logam Zn 2+dan menurunkan konsentrasinya dari 250-300 ppm menjadi 20-50 ppm. Waktu kontakoptimum dicapai setelah satu jam, sedangkanproses sorpsi optimum terjadi pada pH 5.Biomassa S. cerevisiae kurang efektifmenyerap logam Zn 2+ pada konsentrasi rendah,di bawah 20 ppm. Perlakuan biomassa meng-gunakan NaOH menunjukkan kemampuanpenyerapan yang lebih baik jika dibandingkandengan yang diperlakukan menggunakanformaldehida dan pemanasan. Percobaan padaaliran kontinyu yang menggunakan biomassayang diperlaukan menggunakan NaOH,menunjukkan bahwa limbah artifisial Zn 2+dapat diturunkan sampai konsentrasi 24,02-47,95 ppm pada sampling pertama, dan 1,15-10,99 ppm pada sampling kedua. Kombinasipenyerapan menggunakan arang aktif danzeolit dapat menyerap sisa Zn 2+ mencapai batasyang diperbolehkan.

Canteen is a producer of domestic liquid waste that has the potential to cause pollution. Likewise with the student canteen, it has the potential to produce waste that causes environmental pollution if it is not treated properly. The use of Montecarlo software in this study is to support quantitative analysis in predicting potential pollution from Ubhara canteen waste with Crystall ball prediction. The results of laboratory analysis in the form COD, BOD dan TSS, showed that the quality of the canteen waste water did not meet the requirements for wastewater quality standard based on Ministry of Environment Decree No. 112 of 2003. Supported by the results of CB Predictor simulations showing the potential of pollution of the Ubhara canteen waste water to the environment continues to increase significantly, also seen from the Double Exponential Smoothing Method, producing MAD (Mean Absolute Deviation) 170.82, Theil's U 0.9951, and Confidence Interval Lower 5% and Upper 99.5%.
