Abstract

Layanan cuci pakaian ataupun lebih dikenal dengan laundry disaat ini tumbuh dimana-mana, paling utama di wilayah pemukiman. Limbah cair yang dihasilkan mengandung zat pencemar yang dapat dilihat dari parameter pencemar misalnya kadar Chemical Oxygen Demand (COD). Penelitian ini bertujuan untuk mengkaji efektivitas jenis pengolahan dengan lama waktu tinggal dalam menurunkan kadar COD limbah cair laundry, serta pengaruh jenis pengolahan dan waktu tinggal terhadap kadar COD. Jenis pengolahan yang digunakan adalah aerasi, fitotreatment dan kombinasi fito-aerasi dengan menggunakan reaktor batch. Tahap penelitian yang dilakukan dimulai dari penelitian pendahuluan, aklimatisasi tanaman eceng gondok, range finding test, pengolahan limbah cair laundry, dan analisis statistik menggunakan regresi linier. Hasil penelitian menunjukkan efisiensi penyisihan COD pada reaktor aerasi, fitotreatment, dan fito-aerasi masing-masing sebesar 60,74%, 24,65%, dan 79,46%. Efisiensi penyisihan paling besar terjadi di reaktor fito-aerasi.  Hal ini karena proses aerasi dapat meningkatkan kandungan dissolved oxygen di limbah laundry lebih besar. Kandungan dissolved oxygen ini digunakan oleh mikroorganisme yang ada di akar tanaman eceng gondok untuk membatu proses degradasi polutan organik limbah cair laundry. Adapun hasil analisis statistik dapat disimpulkan bahwa jenis pengolahan dan waktu tinggal berpengaruh signifinkan terhadap kadar COD. Kata kunci: Aerasi, COD, Fitotreatment, Laundry, Limbah

Abstract

Sampah menjadi masalah serius di daerah perkotaan. Hal ini disebabkan oleh adanya kepadatan penduduk yang tinggi. Penimbunan sampah terus menerus akan menghasilkan pencemaran pada air lindi, baik yang berupa senyawa organik maupun anorganik termasuk logam berat. Pada penelitian ini dievaluasi penyebaran logam berat timbal (Pb) dan cadmium (Cd) dalam air lindi baik di air lindi maupun di kolam penampungan di TPA Pasuruhan, Kabupaten Magelang. Evaluasi kadar Pb dan Cd juga dilakukan dalam air sumur di sekitar TPA. Sampel air diambil di daerah air lindi inlet pada saluran irigasi, air lindi kolam tampung, sumur pantau dan sumur produksi. Kadar Pb dan Cd dianalisis spektrofotometri serapan atom dan dibandingkan dengan baku mutu Peraturan Menteri Lingkungan Hidup Kehutanan Republik Indonesia Nomor P.59/Menlhk/Setjen/Kum.1/7/2016 untuk air lindi dan air sumur menggunakan baku mutu Peraturan Menteri Kesehatan Republik Indonesia Nomor 32 Tahun 2017 untuk air sumur pantau dan sumur produksi. Hasil menunjukkan bahwa kadar Pb dalam air lindi dan air sumur melebihi baku mutu. Kadar Pb dalam air lindi inlet  0,83 mg/L dan kolam tampung  0,43 mg/L, sedangkan kadar Cd pada lindi inlet diperoleh hasil 0,05 mg/L dan kolam tampung 0,04 mg/L. Kadar Pb sumur pantau 0,05 mg/L dan sumur produksi 0,03 mg/L, sedangkan kadar Cd sumur pantau 0,008 mg/L dan sumur produksi 0,006 mg/L.  Kadar logam Pb dan Cd dalam air sumur pantau dan air sumur produksi masih memenuhi baku mutu.

Abstract

Pencemaran logam berat merupakan salah satu masalah penting yang menimbulkan efek beracun. Logam berat yang terakumulasi pada tubuh manusia akan mengakibatkan berbagai resiko yang berbahaya. Mengingat bahaya yang ditimbulkan oleh logam berat, berbagai metode telah digunakan untuk menurunkan kadar logam berat. Salah satu metode yang digunakan dalam penelitian ini yaitu adsorpsi biosorben selulosa xanthate dari selulosa bagas tebu untuk menjerap logam berat Pb2+ dan Cu2+. Pembuatan biosorben dilakukan melalui proses xhantasi dengan memvariasikan konsentrasi Karbon Disulfida (CS2) yaitu 120%, 140%, dan 160% (b/b) dari jumlah bahan baku. Produk dari reaksi xhantasi selanjutnya dianalisa Derajat Substitusi (DS) dan Derajat Polimerisasi (DP) pada range 0,36−0,39 dan 301−308. Selain Uji Derajat Substitusi (DS) dan Derajat Polimerisasi (DP), karakter dari selulosa xanthate juga dilakukan analisa menggunakan SEM dan FTIR. Karakterisasi tersebut ditujukan untuk mengetahui morfologi permukaan dan perubahan gugus fungsi selulosa xanthate pada berbagai variasi konsentrasi karbon disulfida (CS2). Hasil pengujian menunjukkan bahwa karbon disulfida (CS2) tersubstitusi ke dalam gugus OH pada selulosa bagas tebu, sehingga selulosa xanthate mampu mengadsorpsi logam berat Pb2+ dan Cu2+ dengan kapasitas adsorpsi masing-masing 50,7 mg/g dan 47 mg/g pada konsentrasi Karbon Disulfida (CS2) 120%.

Abstract

Noise is a sound wave generated from a vibrating sound source that causes discomfort to the listener and has an effect on health. Traffic activity is one of the sources of noise and disturbs the comfort of school children. Therefore, this study aims to analyze the noise potential in elementary schools (SD) on the edge of the Kendari City primary road mathematically, then map the results of noise calculations. The sampling technique was carried out by calculating the volume of traffic vehicles such as motorcycles, light vehicles, and heavy vehicles. Measurements were carried out on Monday-Friday at each point one day, the measurement time was at 08.00 - 09.00 WITA. Travel time is done by recording the time required to pass the road segment. Based on these results that the Predicted Noise Level (PNL) calculation, the highest potential noise level is at SDN 7 Kendari at 67.09 dB(A), SDN 37 Kendari at 66.53 dB(A), SDN 6 Kendari at 65, 05 dB(A), SDN 2 Kendari is 64.84 dB(A), SDN 30 Kendari is 64.53 dB(A), and SDN 28 Kendari is 62.48 dB(A). The presentation of data in the form of spatial/map data is very important because of the large number of research locations, with the presentation of the data in the form of a map, making it easier for researchers to analyze the noise potential by making points, so that they become reference materials for the great potential of PNL in Kendari City.

Abstract

The results of the initial analysis carried out by the author occurred because there were several indications of waste problems at PT XYZ. These problems are the difference in actual time and standard time as well as the quality of production results that do not meet company standards. The purpose of this research is to determine the type of relationship between waste and the type of waste produced in the production process at PT Best Jeans Indo Citra Nusa. This research applies a mixed method research method, combining quantitative and qualitative data through observation, interviews, and literature study. The study population includes all PT XYZ employees, with a sample of 8 people selected using judgment sampling. The analysis was carried out using the Waste Assessment Method, which aims to identify and evaluate waste in the production process. This method consists of the Waste Relationship Matrix and the Waste Assessment Questionnaire. The occurrence of idle time and defects in the production process at PT XYZ can occur because the company still produces waste in every production process. With this research, it is hoped that companies can make efforts to minimize every process that can produce waste.

Abstract

Fisheries have become one of the main economic sectors in Sidoarjo Regency. X Ltd., an industry producing frozen fish, already has a Wastewater Treatment Plant, but the WWTP effluent produced does not meet quality standards. Based on these problems, it is necessary to evaluate the WWTP and then re-plan the WWTP so that the effluent results meet quality standards. The evaluation method was carried out by analyzing samples of wastewater from each WWTP unit, measuring the dimensions of each WWTP unit, and comparing the detention time parameters with the design criteria. The evaluation results showed that the existing WWTP conditions did not meet the design criteria, and the existing WWTP effluent results did not meet the quality standards of East Java Governor Regulation No. 72 of 2013. The recommendation from the evaluation results is to re-plan the WWTP using an Anaerobic-Aerobic filter system. The units used are screens, equalization tanks, initial settling tanks, anaerobic filter tanks, aerobic filter tanks, and final settling tanks. The WWTP plans to treat wastewater with a discharge of 3 m 3 /day and characteristics of the wastewater, i.e., TSS 179 mg/L, BOD 239 mg/L, COD 586 mg/L, and Ammonia 29 mg/L. The WWT dimension is 6m x 1m x 1.5 m.

Abstract

The main problem in the Bakung final processing place is the infiltration of leachate with high concentrations of organic and inorganic substances. Leachate from landfills is usually characterized by a foul odor, a black color, high COD values, and toxicity. This is very dangerous if it is directly flown into the ground or water body because it can pollute the environment. Therefore, it is necessary to carry out effective leachate treatment. One way to treat leachate is using Fenton method, which is a development of  advanced oxidation processes technology. The objectives of this research are to treat leachate using the Fenton method and determine the effect of the Fenton molar ratio (1:150, 1:200, 1:250) and reaction time (30, 60, 90, 120 minutes) on color and COD degradation. Optimum conditions were achieved at a Fenton molar ratio of 1:150 and a reaction time of 120 minutes, with maximum color and COD degradation percentages of 91.4% and 92.4%, respectively. The results of this research show that the Fenton method is very effective on color and COD degradation in leachate and has met the leachate water quality standards for businesses and/or final waste processing activities.

Abstract

The most common problem encountered in the use of well water is the presence of metal contaminants, particularly iron (Fe) and manganese (Mn). One alternative solution is the use of filtration with zeolite and activated carbon. This research aims to improve the quality of well water by reducing Fe, Mn, and turbidity levels using filtration technology. The treatment reactor consists of two reactors with the difference between reactors 1 and 2 lies in the type of media used. Reactor 1 uses zeolite media, and reactor 2 uses activated carbon. The filtration column used is a PVC pipe with a diameter of 10 cm and a length of 1 m. The independent variable in this study is the composition of the filtration media, consisting of a combination of quartz sand-zeolite and quartz sand-activated carbon. The research findings show that in reactor 1, the decrease in Fe levels from the first day to the third day is 0.4975 mg/L, 0.6175 mg/L, and 0.605 mg/L, whereas in reactor 2, it is 0.9175 mg/L, 0.7725 mg/L, and 0.685 mg/L. The decrease in Mn levels in reactor 1 over three consecutive days is 0.08 mg/L, 0.07 mg/L, and 0.05 mg/L, while in reactor 2, it is 0.12 mg/L, 0.09 mg/L, and 0.06 mg/L. The decrease in turbidity levels in reactor 1 consecutively is 20.825 NTU, 13.305 NTU, and 11.09 NTU, while in reactor 2, it is 21.4775 NTU, 18.36 NTU, and 12.23 NTU. These filtration results have met the clean water quality standards according to PERMENKES No. 32 of 2017.
