Abstract

Peat water is the kind of surface water that which widely available in the swampy area and lowlands that require more treatment so that can beclassified as a clean water and can be drunk. One of the alternative technology that can be used for peat water treating is membrane technology. The first challenge of the membrane technology is fouling. The purpose of this research is to learn the affectivity and efficiency of the cleaner materials likeNaOH and detergent in the regeneration process of ultrafiltration membrane at the peat water filtering operation. This research was done by using ultrafiltration membrane that the peat water as the feed. The used methodwas cross flow system with variations were pressing operation 1 bar and 1,5 bar and concentration of NaOH and detergent 1%, 1,5%, and 2%. The filtering process of peat water carried on for 120 minutes and the each cleaning time was 20 minutes. The highest of cleaning affectivity was reached 21,14% using detergent 2%. The highest of cleaning efficiency based on recovery flux was 84,88% and based on resistance removal was 21,09%.Key words : Cleaning affectivity, cleaning efficiency, peat water, ultrafiltration membrane

Abstract

Adsorption is the binding process of a molecule from the gas or liquid phase into an adsorbent from an adsorbate. Adsorption is one method of processing peat water. Tropical Almond shell is one of the organic wastes that has the potential to be used as an adsorbent because it contains cellulose, hemicellulose and lignin. The purpose of this study was to determine removal efficiency of Fe and organic matter in the peat water, calculating the adsorption capacity and determine thw appropriate type of isotherm. Variable that was given in this research consisted by mass variation 4,5 dan 6 gr and contact time of 30, 60 and 90 minutes.the resultsof the study showed the efficiency of removal of Fe and organic matter concentrations higher 53,62% and 41,39% by mass of adsorbent 6 gr with a contact time 60 minutes. Mettal adsorption capacity of Fe achieved the highest on the mass of 6 grams with a contact time of 60 minutes amounted to 0,00754 mg Fe/gr, while the adsorption capacity of organic matter achieved the highest on the mass of 4 grams with a contact time of 60 minutes as amounted to 10,125 mg organic matter/gr.

Abstract

The use of fossil fuels is increasing every year, necessitating finding alternative energy sources as a substitute for fossil fuels. Alternative energy sources that can be used as renewable energy are biobriquettes derived from biomass. A very abundant agricultural waste, such as WWTP sludge, palm kernel shell production, but not utilized optimally. The purpose of this study was to study the effect of variations in tapioca adhesive concentration in the manufacture of biobriquette on the analysis of proximate and compressive strength produced. The process of making biobriquette in this study with variations changed the concentration of tapioca adhesive 5%, 8% and 11%. Fixed variations used were carbonization temperature of 300oC mud, 500oC rubber seed shells for 1 hour, raw material composition of WWTP sludge charcoal and 60%: 40% of the total weight of 10 gram briquettes and pressing pressure of 100 kg/cm2. Carbonization is carried out using furnaces and drying is carried out in a room 24 hours and then oven for 1 hour at a temperature of 105oC. The results showed that the best briquettes lie in the variation of 11% adhesive concentration which produces a compressive strength of 11,55 kg/cm2, moisture content of 7,5%, ash content of 7%, volatile content of 10,50% and carbon content of 75%.Keywords: biobriquette, rubber seed shell, carbonization, waste WWTP palm oil production, compressive strength.

Abstract

Pertamina Dumai Refinery has carried out Open Access Project which changed the processed crude from initial design by substituting SLC with another "light sweet" crude from outside Riau. The percentage of this replacement reaches 50% of the total crude intake. This study reviews the impact of changes in the composition of processed crude oil on the composition of produced green coke. The research was conducted throughout 2018 with preliminary data gathered since 1996. Green coke samples were taken per month for properties analysis such as moisture content, volatile matters, ash content, sulfur content and fixed carbon, to calculate conversion value of green coke. The conclusion of this research is that the fluctuations in the crude composition were quite significant towards the composition and the conversion value (ton to barrel) of the produced green coke.Keywords: crude oil, conversion, green coke, volatile matter

Abstract

Peat water in Indonesia has the potential a source of clean water because of its ample availability, but in terms of qualitatively it still does not meet the standards of clean water quality according to Permenkes No. 32 of 2017, such as organic substances and colors that are still high. This weakness can be overcome through processing using the coagulationflocculation method with the addition of natural coagulants. One of the natural coagulants that can be used in the coagulation-flocculation process is averrhoa bilimbi. Averhhoa bilimbi as a coagulant can reduce color parameters and organic matter in peat water because it has advantages in the coagulation-flocculation process due to its high acid concentration. This study aims to determine the effect of averrhoa bilimbi coagulant dosage and pH in removing organic matter and color in peat water. Keywords: Peat Water, Dosage, pH, Coagulation-Floculation, Averrhoa bilimbi.

Abstract

Water sources in peaty areas or swampy areas are generally shallow with brown water, high levels of humic acid, organic matter and iron. Rubber fruit shell is one of the organic wastes that has the potential to be used as an adsorbent because it contains quite a lot of lignin. This study aims to determine the effect of adsorbent mass and stirring rate in the adsorption process using rubber fruit shell adsorbents in peat water treatment.

Abstract

Peat water is a type of surface water that contains natural organic materials, so that cause brownish-colored water, taste and smell, in addition to the color of peat water caused by organic acid. It viewed from quality, peat water has not include the standard of drink water quality standard. Peat water needs treated to be used as a source of clean water and drink water. The adsorption process can be one of the peat water treatment alternatives by utilizing one of agricultural industry waste in the form of biosolid Palm Oil Industry as natural adsorben. The purpose of this research is to know the effect of stirring speed and contact time on colour in peat water. In this study, variations of stirring speeds were used at 90, 120 and 150 rpm and contact time variation at 30, 60, 90 and 120 minutes. The best results at 150 rpm stirring speed and 90 minutes contact time were found to decrease the efficiency of colour degradation is 238,400 mg/g and efficiency decrease equal to 68,703%.Keywords: Peat water, Biosolid, Adsorption
