Abstract

Domestic wastewater in the culinary area is waste water produced from several restaurants. The problem of liquid waste needs to get serious attention, because it has complex characteristics and the remaining results of these activities can cause the volume of wastewater with a high contaminant load that flows continuously over a long period of time. One way to manage the environment is through physical processing, namely by pre-treatment of sedimentation and biological treatment by biofilter anaerobic processes. Anaerobic biofilter is a biological treatment, which uses media as a place to grow and develop microorganisms, with no oxygen in the reactor. The parameters in liquid waste processing consist of three, namely physical parameters, chemical parameters and biological parameters. In the method of combating liquid waste here uses chemical parameters, namely BOD and TSS. Where BOD (Biochemical Oxygen Demand ) is the number of milligrams of oxygen needed by aerobic microbes to decompose karon organic matter in 1 L of water for 5 days at a temperature of 20˚C ±1˚C. Whereas for TSS (Total Suspended Solid) as the residue from total solids held by a filter with a particle size of maximum 2μm or greater than the size of colloidal particles, which include TSS are mud, clay, metal oxides, sulfides, algae, bacteria, and fungi . The aim of this research is that the liquid waste from the activity can be reused as clean water by anaerobic biofilter method using BOD and TSS parameters. The variables used are operational time. Reactor I and reactor II contain media arranged from the bottom up, namely rock fragments, gravel, shells and gauze. The operational time variations used are 0 hours as t0 or the first time the waste exits the reactor, and the time is 2 hours, 4 hours, 6 hours, and 8 hours is a periodic observation of operational time. The results showed that anaerobic biofilter has the ability to reduce the concentration of BOD (Biological Oxygen Demand) and TSS (Total Suspended Solid). Based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.68 / Menlhk / Setjen / Kum.1 / 8/2016 concerning Domestic Waste Water Quality Standards, the characteristics of wastewater are obtained before treatment (pretreatment) which is 28- 31 ° C; pH 9,3-10; BOD 30 mg / L; and TSS 29 mg / L. Decreasing the initial state in reactor I for BOD is 25 mg / L. Whereas for the decrease in TSS is 16 mg / L. The results showed that anaerobic biofilter with pumice, gravel and clam shell media had the ability to reduce BOD and TSS concentrations significantly. The percentage decrease in concentration in reactor I was greater than that of reactor II, with an operational time of 6 hours for BOD allowance of 73,54%. While the operational time of 8 hours for TSS is 81,39%.

Abstract

Increased population growth results in increasing human needs over time. Meeting the high needs triggered the development of industries that meet the needs. Problems arise from the many industries that emerge, one of which is an environmental problem. Many industries in Indonesia have not used good waste treatment standards, causing pollution from the rest of the production process in the industry, one of which contains heavy metals such as Pb, Zn, Mercury and so on. Heavy metal is a type of pollutant that is harmful to plants, animals and humans through the process of bioaccumulation in the food chain. The purpose of this research is the content of heavy metals that are harmful to the sustainability of ecosystems in the environment requires a long time so that one way to prevent heavy metal compounds that can be released to the environment is by managing the bioremediasi process with fragrant root medicinal plants (Vetiveria Zizanioides) which has hyperaccumulator properties which can absorb one of the heavy metals namely Cadmium (Cd) and Lead (Pb).

Abstract

ndonesian turpentine contains 65-85% α-pinene, 1% camphene, 1-3% β-pinene, 10-18% 3-carene and 1-3% limonene. The largest content of turpentine is alpha pinene. Alpha pinene is also a monoterpene compound that has double bonds and is the main raw material in the perfume industry. In addition, alpha pinene is also an important raw material for the manufacture of fine chemicals that have high sales value such as pine oil, camphor and alpha terpineol. To increase the sale value, alpha pinene can be further processed into derivative compounds such as alpha terpineol and alpha terpinyl acetate. Both are valuable derivative compounds used in the perfume industry and the pharmaceutical industry. Hydration is the reaction between alpha pinene and water to produce alpha terpineol compounds. In the reaction process that will be carried out on alpha pinene usually uses a catalyst that can accelerate the reaction rate without becoming a byproduct, catalyst used in this study is a type of resin. This study aims to study the effect of temperature variables at temperatures of 65, 75, 85 and 950C. The conversion of alpha pinene increases with increasing reaction temperature. Assuming a reversible reaction, the relationship of temperature to each reaction rate constant is determined according to the Arrhenius equation.

Abstract

The use of kepok banana peel activated carbon (AC-KPK) and nipa shell activated carbon (AC-TN) to adsorb phosphate ions in laundry waste has been successfully carried out. Characterization of activated carbon was carried out with SEM-EDX. The results of the morphological analysis showed that the pore sizes in AC-KPK and AC-TN were included in the macropore category. The elemental content of the AC-KPK adsorbent is C 74.9%; 23.6% O and 1.5% K, whereas in the AC-TN adsorbent it was observed that C elements were 70.7%; O 25.5%; K 2.0% and other elements such as Ca, Na, Mg and Cl are contained in small quantities. The optimum contact time needed by AC-KPK to adsorb phosphate ions in laundry wastewater is 15 minutes with an adsorption efficiency of 98.83%, the AC-TN adsorbent is 5 minutes with an adsorption efficiency of 99.52%, and the combination of AC-KPK&AC- TN resulted in a contact time of 5 minutes with an adsorption efficiency of 99.91%. The adsorption kinetics of phosphate ions with the three adsorbent media followed the pseudo second order model with adsorption rates for the adsorbents AC-KPK, AC-TN, and the combination AC-KPK & AC-TN respectively 3.9400 g/mg.min; -28.7119 g/mg.minute; and -10.8895 g/mg.min.

Abstract

Industri Obat Tradisional menjadi salah satu industri yang menghasilkan limbah cair. Sebelum limbah cair dibuang ke lingkungan terlebih dahulu diolah di Instalasi Pengolahan Air Limbah (IPAL). Hasil pengujian di IPAL Industri Obat Tradisional menunjukan efektivitas dalam menurunkan TSS 10,7%; BOD 12,97%; COD 5,4%; dan menurunkan pH 0,04. Dari efektivitas tersebut perlu dilakukan upaya optimalisasi pengolahan limbah cair agar lebih efektif. Optimalisasi dilakukan dengan mengolah limbah cair menggunakan teknologi bioremediasi berupa konsorsium bakteri aerob. Tujuan penelitian ini yaitu untuk mengetahui pengaruh dan mencari konsorsium bakteri aerob yang paling efektif dalam menurunkan kadar pH, TSS, BOD, COD, dan Fenol. Penelitian dilakukan dengan mengkonsorsiumkan bakteri AB (Bacillus s. & Pseudomonas a.); AC (Bacillus s. & Klebsiella sp.); BC (Pseudomonas a. & Klebsiella sp.); dan ABC (Bacillus s., Pseudomonas a., & Klebsiella sp.). Hasil penelitian menunjukan konsorsium bakteri ABC mampu menurunkan semua parameter pencemar dan merupakan variasi yang paling efektif dalam menurunkan kadar pH, TSS, BOD, COD, Fenol sebesar 2; 60 ppm; 36 ppm; 78 ppm; 0,002 ppm dan telah memenuhi baku mutu. Kata kunci: bioremediasi, konsorsium bakteri aerob, limbah cair industri obat tradisional
