Abstract

Generally, peat water quality not suitable with water quality standards Permenkes No. 416 / Menkes / Per / IX / 1990. Peat water treatment commonly used to produce treated water still above the quality standard. One of the peat water treatment methods used in this study is combination of coagulation-flocculation and ultrafiltration membrane. This study aims to determine the effect of coagulants Poly Aluminum Chloride (PAC) to decrease colour, organic matter and turbidity, determine the performance of membrane for flux and rejection of colour, organic matter, and turbidity with and without pre-treatment of coagulation flocculation, determine decrease of colour, organic matter, and turbidity in peat water treatment using ultrafiltration membrane with pre-treatment of coagulation-flocculation. Peat water treatment by flocculation and coagulation combination of ultrafiltration membrane using Poly Aluminum Chloride (PAC) as coagulant with dose 150 mg / L, and varying the ultrafiltration membrane feed pressure of 0.5; 1 and 1.5 bar.

Abstract

Quantitatively, peat water has the potential to be a source of water that can be processed into clean water, but qualitatively the utilization of peat water is still experiencing problems such as high iron (Fe) content and high color. The use of peat water in the long term will have a negative impact on health, so it needs to be processed into clean water. This study aims to study the effect of adsorbent dose and contact time on the efficiency of removal of iron (Fe) and the color of peat water and the adsorption capacity of the adsorption process using physically activated peat clay as an adsorbent. This study varied the adsorbent dose of 4 g/L, 8 g/L and 12 g/L with adsorbent particle size -100 +120 mesh and contact time variations of 120 minutes, 140 minutes and 160 minutes with a stirring speed of 150 rpm. The results showed that the best effect on the removal efficiency was obtained at an adsorbent dose of 12 g/L and a contact time of 160 minutes with a metal removal efficiency of 84.42% and a color removal efficiency of 96.41%. The best effect on the adsorption capacity was the adsorbent dose of 4 g/L and a contact time of 160 minutes with a value of iron (Fe) adsorption capacity of 0.250 mg/g and a color adsorption capacity value of 114.68 mg/g.Keywords: Peat Water, Peat Clay, Adsorption, Physical Activation, Iron Metal (Fe) and Color

Abstract

Produksi minyak sawit yang tinggi berbanding lurus dengan produksi limbahnya. Lumpur kelapa sawit merupakan larutan buangan yang dihasilkan selama prosespemerasan dan ekstraksi minyak.Limbah lumpur kelapa sawit disamping sebagaisumber hara makro dan mikro yang penting bagi tanaman, juga sebagai sumberbahan organik dan berperan pada perbaikan sifat fisik dan kima tanah. Limbahpadat lainnya yang belum dimanfaatkan secara maksimal adalah serat buahkelapa sawit yang juga mengandung unsur hara. Dari kedua potensi limbahpadat kelapa sawit menunjukkan bahwa sangat perlu dilakukan pengolahankhususnya pada limbah lumpur dan serat buah dimana berdasarkan hasil analisalaboratorium mengandung unsur hara yang baik untuk dikonversi menjadi pupukkompos. Mikroorganisme lokal (MOL) adalah mikroorganisme yangdimanfaatkan sebagai starter atau aktivator dalam pembuatan pupuk organikpadat maupun pupuk cair. Bahan utama MOL terdiri dari beberapa komponenyaitu karbohidrat, glukosa, dan sumber mikroorganisme. Tujuan penelitian iniadalah mengetahui kemampuan MOL sebagai aktivator dalam prosespengomposan limbah lumpur dan serat buah kelapa sawit yang disterilkan dantidak disterilkan. Dari hasil penelitian dapat ditarik kesimpulan bahwamikroorganisme pada MOL yang berperan sebagai pendegradasi pada prosespengomposan lumpur dan serat buah kelapa sawit. Hal ini berdasarkan hasilanalisa proses fermentasi tapai singkong menjadi MOL dimana jumlahmikroorganisme pada hari pertama sebesar 403,45mg/l dan pada hari kelimajumlah mikroba meningkat menjadi 456,10 mg/l. Selain itu dapat dilihat jugabahwa bahan baku yang disterilkan untuk parameter kualitas kompos antara lain: N, P, K, C, C/N,Mg, Ca, temperatur, pH, dan kadar air, mempunyai nilai yangmendekati SNI berbanding bahan baku yang tidak steril. Penggunaan MOLsebagai sumber mikroorganisme dalam proses pengomposan dapat dijadikanalternatif sebagai bioaktivator yang ekonomis dan ramah lingkungan.

Abstract

Peat water has potential as a source of clean water because of its ample availability but qualitatively it still does not meet the standards according to Permenkes No.32 Tahun 2017 quality of clean water, such as organic substances and colors that are still high. This study uses a coagulation-flocculation methods using a Averrhoa bilimbi juice and alum. The variation are dosage averrhoa bilimbi juice (22,5 ml, 25 ml, 27,5 ml) with alum 0,25 gr and pH 4, 5, 6, 7, 8 in setting aside color and organic matter. The results showed that the treatment of peat water in the treatment variation 27,5 ml, alum 0,25 gr and pH condition 4 is already the best result for water quality requirements. Decreasing the colour with value  95,61% and organic substances is about 71,18%.

Abstract

Peat water in quantitative subject is very potential to be proceed for cleaned water in water resources. But in qualitative aspect, there is so much problem, there are the colour (dark brown), low PH, and high organic inside. The using of Biocoagulan is the best way as alternative for decrease the using of sintetic coagulant that can influence our health for a long term use. The purpose of this experiment is for knowing the effect of dosage (V/V), speed of stirring, and PH for decreasing colour and organic substances (KMnO4) in peat water with using biocoagulant aloevera gel. The variation are dosage of aloe vera gel (10 mL/L, 15mL/L, 20 mL/L ), the speed of stirring (100 rpm ,150 rpm and 200 rpm) with the PH constantly in the nature of PH peat water it self and PH 7. The result show that peat water treatment with using aloe vera gel with variation 15 ml/l, speed of stirring 200 and PH7 is the best result for decreasing the colour with value 80,66 % and organic substances is about 69,69% Keywords : Peat Water, Stirring Speed, Coagulation-Floculation, Biocoagulant, Aloe Vera
