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

As a company laboratory in East Java produces waste at levels that do not meet the standards permitted by government authorities. The main problem is the COD value, NH3-N levels and pH that are not suitable. The study was conducted to reduce COD levels of NH3-N and neutralize pH with the chosen method. This study aims to determine the effect of the amount of adsorbent and the use of anion exchanger on the pH of the wastewater, the COD concentration of the wastewater, and the total ammonia concentration of the wastewater. This research begins with drying of activated carbon and activation of Silitte MA-12 anion resin. Silitte MA-12 anion resin 100 gr by soaking into the waste and adding activated carbon of 45.5%, 50.55%, 65.72%, 80.89%, and 96.05%. The analysis was carried out after 24 hours of immersion. The Silitte MA-12 resin used causes an increase in pH from 1-2 to 6-7. The results of this study are that the greater the addition of activated carbon percent does not significantly affect the final pH of the sample, the COD value produced is getting smaller from the initial value of 1592 mg/L to 40-200 mg/L with a standard value of 200 mg/L and ammonia levels. in the sample is getting smaller from the initial value of 752 mg/L to 8-90 mg/L with a standard value of 100 mg/L.

Salah satu industri yang perlu mendapat perhatian adalah usaha industri sarung tenun. Industri ini menghasilkan limbah cair yang dihasilkan dari proses pewarnaan. Pembuangan limbah secara sembarang akan menimbulkan dampak merugikan bagi lingkungan. Oleh sebab itu perlu dilakukan pengolahan limbah terlebih dahulu. Tujuan dari penelitian ini untuk menurunkan kadar COD dan TSS pada limbah cair warna industri sarung tenun. Penelitian ini menggunakan metode adsorpsi menggunakan adsorben Zeolit teraktivasi asam sulfat. Konsentrasi Asam Sulfat yang digunakan adalah 2,5 N. Persen removal COD terendah dengan massa zeolit sebesar 1 gram dengan waktu 60 menit sebesar 30,98% dan  persen removal COD tertinggi dengan massa zeolit sebesar 5 gram dengan waktu 180 menit sebesar 59,61%. Persen removal TSS terendah dengan massa zeolit sebesar 1 gram dengan waktu 60 menit sebesar 74,16% dan persen removal TSS tertinggi dengan massa zeolit sebesar 5 gram dengan waktu 180 menit sebesar 94,05%. Kata kunci: Zeolit, Adsorpsi, Limbah industri warna sarung tenun

Abstract

Ethanol gel is a semisolid fuel made from ethanol by mixing the gelling agent.Ethanol gel has the advantage of facilitating packaging, distribution and storagebecause it does not spill and flow easily. Another advantage of ethanol gel is that itdoes not smoke during the combustion process, does not cause soot and does notproduce harmful gases. This research aims to compare the 2 best gelling agentsand study the effect of adding the gelling agent to the calorific value. The processof making ethanol gel begins by inserting a gelling agent of 4-12% w into a beakerglass. Then add 20 ml of distilled water while stirring until the solution thickens.After that, slowly put 75 grams of 95% ethanol into the beaker which alreadycontains the gelling agent solution. For the manufacture of ethanol gel with astearic acid gelling agent, heating is done first in making the solution and left for 3hours after mixing with ethanol. Based on the analysis, it was found that thehighest calorific value was 12052.7 cal / g with stearic acid gelling agent in theaddition of 12% (% w).

Abstract

The amount of energy needed for daily needs causes fossil energy sources to decrease, so that efforts to develop other energy sources continue to be carried out. Biomass that has undergone further processing can be a renewable energy source. Gasification is one of the processes of processing biomass into a source of energy in the form of gas, but during this process there will be a lot of tar content produced. The amount of tar content needs to be adjusted to the standard tar content in the produced gas. The purpose of this study was to determine, analyze, and understand the effect of adding a wet scrubber to the tar content produced with rice husks as biomass. The provision of water discharge variations of 1.5 lpm, 2 lpm, and 2.5 lpm, as well as the position of the nozzle which is varied in its placement into horizontal, vertical, and collaboration, aims to determine the discharge and compatible nozzle position on the gasifier, which is seen from the tar content. contained in producer gas. The results of this gasification research will be compared with the gasifier without the addition of a wet scrubber.

Abstract

One of the alternatives and renewable energy that is being developed is ethanol.Ethanol is better known as Gasohol. Molasses can make Gasohol through thesynthesis of molasses fermentation using a yeast starter. This study aims toanalyze how the effect of the addition of baker's yeast, the length of fermentationincubation time on the resulting alcohol content. In addition, the yield obtainedfrom the highest amount of ethanol production in the molasses fermentationprocess. Ethanol production through fermentation synthesis using the help ofmicroorganisms Saccharomyces cerevisiae. Based on the objective review, thevariation used is the amount of baker's yeast, namely 0.1; 0.2; 0.3; 0.4; and 0.5%glucose levels. The fermentation times were 24, 48, 72, 96, and 120 hours (T =30?C and pH = 5). Based on these variations, the highest alcohol productionwas 11%, obtained by adding 0.2% of yeast to the glucose content in the solution.The incubation time is 72 hours. The yield obtained for the highest alcoholcontent is 4.48%

Abstract

Industri penyamakan kulit menghasilkan limbah cair, limbah padat, dan gas. Ketiga limbah tersebut limbah cair merupakan limbah yang paling banyak dihasilkan salah satunya limbah logam berat Kromium (Cr). Oleh sebab itu perlu dilakukan pengolahan limbah terlebih dahulu sebelum dibuang ke badan air. Tujuan penelitian ini ntuk mengurangi logam berat dalam limbah cair dapat menggunakan metode adsorpsi, karena lebih ekonimis dan efisien. Daun kelor mempunyai senyawa gugus fungsi yang mendukung dalam adsorpsi sehingga dimanfaatkan sebagai biosorben. Dalam penelitian ini digunakan metode adsorpsi menggunakan biosorben daun kelor teraktivasi H2SO4 untuk menyerap logam berat kromium (Cr).
