Abstract

The demand of energy in the world today has increased exponentially, therefore, more efforts have been focused on looking for alternative renewable sources, such as biodiesel, which involves fuel produced from oil of plant, or animal fat. The objective of the research, therefore, was to utilize the palm oil mill effluent (POME) as a raw material in the production of biodiesel, by applying varying solvent, extraction time and the effluent to solvent ratio. Furthermore, the best output of oil rendement of (81.07%), in comparison with the total sample taken,was obtained using n-hexane, at an extraction time of 3 days, and ratio of 1:1. Furthermore, the output possessed a high acid number. Hence, it is considered in the process of esterification and transesterification, required in the production of biodiesel. The HCl catalyst ratio of 1.25% (%v) was used in the esterification process, and the lowest acid number of 2.08 mg-KOH/gr was obtained, followed by the transesterification process, using 1.5% (%w) of NaOH catalyst of the oil weight. Hence, the characteristics of biodiesel produced were in accordance with SNI 04-7182-2006.Keywords: POME, Biodiesel, Esterification and Transesterification, Extraction, n-Hexane

Abstract

The pulp and paper industry wastewater has not met the environmental uality standards set by the government so it may causes pollution to the environment; therefore, it is necessary to find a better wastewater treatment. The problem of this study is how to find the wastewater treatment alternative in order to get a more effective and efficient treatment. Fenton reagents are H2O2 compounds (hydrogen peroxide) with iron catalysts and is one of the Advance Oxidations Process (AOPs) methods, which can be used as an alternative to process wastewater from the pulp and paper industry. In this study, the ratio of Fenton reagent molar concentration, temperature, and stirring time were varied, with stirring speed of 300 rpm, Fenton reagent volume of 25 mL, and pH set at 3. The visible parameters in this study were COD and TSS degradation. From this study, the best ratio of Fenton reagent is 1:2000, where this ratio can reduce the COD from 1002 mg/L to 176.05 mg/L and the TSS from 125 mg/L to 49.3 mg/L. This value has met the environmental quality standards for the pulp and paper industry set by the Indonesian government.

Abstract

Nowadays, environmental pollution caused by industrial wastewater is quite apprehensive. Most of textile industries used synthetic dyes. Procion red is one of the synthetic dyes that often used in textile industries and classified as a reactive dye that is difficult to decompose in nature and contain harmful toxins. One of the colored wastewater treatment process is by using Fenton reagent and TiO2 catalyst (Fenton-TiO2) as one of Advanced Oxidation Processes (AOPs). The objective of this research is to treat of procion red synthetic dye by using Fenton-TiO2 method and study the effect of procion red concentration, reaction time and the concentrations of TiO2 catalyst on color and COD degradation. In this experiment, the concentrations of procion red were varied between 150-300 ppm, the concentrations of TiO2 catalyst were varied from 0.05 to 0.4% (w/v) and the reaction time of 5 to 20 minutes. The optimum condition was achieved by using procion red concentration of 150 ppm with TiO2 catalyst concentration of 0.4% and reaction time of 20 minutes, which the maximum color and COD degradation of 98.67% and 92% were achieved respectively. This condition was applied to the real wastewater of textile home industry in Palembang. The color and COD degradation of 59% and 44% were found respectively after 220 minutes of reaction.

Abstract

The anaerobic ammonium oxidation (anammox) as a new biological approach for nitrogen removal has been considered to be more cost-effective compared with the combination of nitrification and denitrification process. However, the anammox bioreactors are mostly explored at high temperature (>300C) in which temperature controlling system is fully required. This research was intended to develop and to apply anammox process for high nitrogen concentration removal at ambient temperature used for treating wastewater in tropical countries. An up-flow biofilm column reactor, which the upper part constructed with a porous polyester non-woven fabric material as a carrier to attach the anammox bacteria was operated without heating system. A maximum nitrogen removal rate (NRR) of 1.05 kg-N m3 d-1 was reached in the operation days of 178 with a Total Nitrogen (TN) removal efficiency of 74%. This showed the biofilm column anammox reactor was successfully applied to moderate high nitrogen removal from synthetic wastewater at moderately low temperature. Keywords: Anammox, biofilm column reactor, ambient temperature, nitrogen removal

Abstract

ABSTRAKLindi  adalah cairan yang ditimbulkan oleh sampah akibat masuknya air eksternal yang dapat melarutkan materi-materi terlarut, termasuk materi-materi organik hasil dekomposisi secara biologi. Lindi dari sebuah landfill (TPA) mengandung zat organik dan anorganik dalam konsentrasi yang tinggi. Dengan adanya gaya gravitasi maka lindi yang terbentuk akan bergerak ke dasar landfill (TPA) akan masuk ke dalam tanah dengan membawa bahan cemaran baik material tersuspensi maupun material terlarut yang dapat mencemari air tanah. Salah satu proses pengolahan lindi adalah dengan menggunakan reagen Fenton dan adsorpsi yang termasuk dalam teknologi Advanced Oxidation Processes (AOPs). AOPs didasarkan pada pembentukan spesies yang sangat reaktif seperti radikal hidroksil (OH•) yang efektif untuk menurunkan COD, BOD dan TSS. Penelitian ini bertujuan untuk mengolah lindi menggunakan reagen Fenton dan adsorpsi serta mempelajari rasio molar Reagen Fenton dan  waktu pengadukan terhadap penurunan COD, BOD dan TSS. Pada penelitian ini lindi diolah selama 30-120 menit. Kondisi optimum dicapai pada rasio molar 1:200, waktu pengadukan 120 menit, dan adsorpsi menggunakan karbon aktif selama 120 menit dimana penurunan COD, BOD dan TSS maksimum yang dicapai berturut-turut 95%, 95% dan 92% dengan nilai konsentrasi akhir 96 mg/L, 25,5 mg/L% dan 90 mg/L.Kata Kunci: Lindi, Reagen Fenton, AOPs, COD, BOD, TSS ABSTRACTLeachate is a liquid generated by waste due to the entry of external water that can dissolve dissolved materials, including decomposition of organic matter biologically. Leachate from a landfill (TPA) contains organic and inorganic substances in high concentrations. by gravitational force, the leachate formed will move to the bottom of the landfill (TPA) and will enter the soil by carrying contaminated material, both suspended material and dissolved material that can pollute ground water. One of the leachate treatment processes is using Fenton reagent and adsorption. Fenton method included in Advanced Oxidation Processes (AOPs) technology. AOPs are based on the formation of highly reactive species such as hydroxyl radicals (OH•) which are effective for reducing COD and BOD. This study aims to treat leachate by using Fenton reagent and adsorption. The effect of reagent Fenton molar ratio and stirring time on degradation of COD, BOD and TSS were also investigated. In this study leachate was processed for 30-120 minutes. the optimum conditions were achieved at a molar ratio of 1: 200, stirring time of 120 minutes, and adsorption using 120 minutes of activated carbon where the maximum decrease in COD, BOD and TSS achieved was 95%, 95% and 92% with a final concentration of 96 mg/L, 25.5 mg/ L and 90 mg/ L.Keywords : Leachate, Fenton Reagent, AOPs, COD, BOD, TSS

Abstract

The number of laundry industry has been increasing rapidly which influences the amount of detergent usage in the washing process. Generally the laundry industries dump their wastewater directly to environment without any treatment. Phosphate contained in detergent shall accumulate in the environment then finally would cause eutrofication where the water body becomes rich of dissolved nutrient which effects the dissolved oxygen contained in water body. One of wastewater treatment methods is adsorption. Two different kinds of adsorbents were applied in this investigation namely activated carbon and natural zeolite. Synthetic laundry wastewater was used in order to control the phosphate concentration. The objective of this experiment was to study the removal of phosphate concentration of each adsorbent filled in adsorption column by using circulation method. The column has 1 inch of diameter, 50 cm of height, and 50 ml/minute of flowrate. The concentration of phosphate was varied between 2-8 mg/l whereas the adsorbent height in the column was varied between the ranges of 10-40 cm. The size of both adsorbents was 10 mesh. It was found that the natural zeolite was superior to remove the phosphate compared to activated carbon. The highest phosphate removal of 90% was obtained by using 40 cm of natural zeolite height in the adsorption column when make use the phosphate concentration of 2 mg/l.

Abstract

Masyarakat Indonesia banyak bergerak di bidang industri makanan, perikanan, dan pertanian. Hasil industri tersebut antara lain, kerupuk, kemplang, dan dodol. Beberapa produk tersebut dalam pengolahannya harus diolah lebih lanjut dengan proses pengeringan. Proses pengeringan yang digunakan masyarakat umumnya menggunakan pengeringan konvensional/tradisional yaitu dengan menjemur produk di bawah sinar matahari selama beberapa waktu. Metode tersebut memiliki banyak kelemahan yaitu, membutuhkan waktu pengeringan yang lama,  lahan  yang  luas dan mudah  terkontaminasi  debu  atau serangga. Untuk  mengatasi  masalah  tersebut, dirancang  suatu alat  pengering yang  tertutup  berbasis  tenaga  matahari  namun menghasilkan efisiensi pengeringan yang lebih besar. Berdasarkan hasil penelitian Dosen Jurusan Teknik Pertambangan Fakultas Teknik Universitas Sriwijaya mengenai rancang bangun Teknologi Tepat Guna (TTG) alat pengering solar corp dryer dengan kolektor undulatif meningkatkan efisiensi alat karena menyerap panas lebih cepat. Selain itu alat pengering solar corp dryer sederhana dalam pembuatannya. Alat ini dapat mengeringkan hasil industri berupa olahan makanan ataupun hasil perikanan dan pertanian dengan lebih higienis, mengurangi kotoran debu dibanding dijemur biasa. Teknologi Tepat Guna (TTG) solar corp dryer diharapkan dapat membantu masyarakat untuk meningkatkan produksi pengeringan industri rumah tangga, pertanian, dan perikanan. Kegiatan pengabdian pada masyarakat ini dilaksanakan secara langsung di SMK Lingua Prima, Kabupaten Ogan Ilir, Indralaya Propinsi Sumatera Selatan dengan mengikut sertakan siswa dan guru di sekolah tersebut. Kegiatan ini bertujuan agar siswa dan guru setempat dapat mengaplikasikan dan mengembangkan teknologi ini untuk dapat dimanfaatkan oleh masyarakat lingkungan sekitar yang notabene melakukan kegatan pengeringan untuk hasil pengolahan bahan makanan, hasil pertanian, dan hasil perikanan. Hasil sosialisasi menunjukkan jika  siswa maupun guru antuasias dan mengapresiasi kegiatan ini dan berminat untuk mengaplikasikan teknologi tepat guna ini.

Abstract

Tofu production is known to generate large amounts of wastewater containing a variety of organic compounds, chemicals, and potentially hazardous substances. It is very important to apply proper treatment of harmful substances that impact this wastewater. The aim of this study is to explore advanced techniques for treating tofu wastewater by combining multilevel filtration and TiO2 photocatalysis methods. To evaluate the efficiency of the treatment process, influent and effluent parameters, including pH, total suspended solids (TSS), and chemical oxygen demand (COD), are carefully monitored and measured. The results clearly demonstrate the impressive removal efficiency achieved through the combined use of multilevel filtration and TiO2 photocatalysis in treating tofu wastewater. The treated wastewater showed a promising efficiency in pH (100%), a significant decrease in TSS (40%), and COD (72%). the final measurements of pH met the standards set by government regulations, indicating successful remediation of these specific parameters. Even though TSS and COD haven't met the standard limits, each of them shows a very promising efficiency improvement. Towards the end of this study, it is suggested that the combination of these methods holds promise for effectively remediating tofu wastewater.

Abstract

Various studies and research have been conducted to find alternatives to liquid insulation. One that is considered the most potential is vegetable oil since it has various advantages, including non-toxic, biodegradable, renewable waste products due to reactions in the form of CO2 and water, high flash points, and better thermal characteristics. In this study, Palm Oil Mill Effluent (POME) was used as the raw material for insulation oil with the addition of an additive in the form of nano-silica, which improves the quality of the insulation oil. As for determining the feasibility of insulation oil, characteristic tests were carried out in the form of density, viscosity, moisture content, acid number, pour point, flash point, and breakdown voltage. Based on the results of the tests, it was obtained that the lowest density in pure oil was 0.8757 g / cm³, the lowest viscosity in oil with the addition of 0.13 wt% nano-silica was 4.0248 cSt, and the lowest acid number in pure oil was 0.5797 mgKOH / g. It was also discovered that the pour point value is the same for each sample, the moisture content is 0.05%, the flashpoint is > 104 °C, and the breakdown voltage is ≥ 60 kV for each sample. The data show that the insulation oil made from POME has the potential to be used as an alternative to insulation oil.
