Abstract

ABSTRACTSurabaya River is a source of raw water for the needs of the community in Surabaya and its surrounding areas, including for industrial and the Surabaya water supply company. Along with the rapid growth of settlements and the development of the industrial sector, the Surabaya River pollution level has increased so that the quality of the water does not meet the quality standards required as raw water for drinking water. The most potential parameter that causes the level of pollution is organic pollutants. The concentration of some water quality parameters including organic pollutants in the Surabaya River has exceeded class I water quality standards based on Government Regulation (PP) No. 82 of 2001, namely for allotment of raw water for drinking water. The purpose of this study was to improve the raw water quality such as parameters of suspended solids (TSS), organic substances, detergents and manganese (Mn) through the application of biofilter technology. The study was conducted by operating a biofilter pilot plant consisting of a lamella-type settling tank and a biofilter reactor filled with wasp-type nesting media. The results showed that the biofilter process used can reduce the concentration of TSS, organic matter, detergents and Mn in raw water. In general, the longer the hydraulic residence time (HRT) in the biofilter pilot plant, the greater the efficiency of removing TSS, organic matter, and detergent in raw water. The experiments results at the conditions of the shortest total HRT of 81 minutes, including HRT of 36 minutes in the settling tank and HRT of 45 minutes in the biofilter reactor, could obtain TSS removal efficiency of 46.92%, 15.97% for organic matter, and 55% for detergent, where the concentration of these parameters meets the quality standards for drinking water.Keywords: biofiltration, HRT, drinking water, water qualityABSTRAKSungai Surabaya merupakan sumber air baku untuk kebutuhan masyarakat di wilayah Surabaya dan sekitarnya, termasuk untuk kebutuhan industri dan air baku PDAM kota Surabaya. Seiring pesatnya pertumbuhan pemukiman dan perkembangan sektor industri, mengakibatkan tingkat pencemaran Sungai Surabaya semakin tinggi sehingga kualitas airnya tidak memenuhi ketentuan baku mutu yang dipersyaratkan sebagai air baku air minum. Parameter yang paling potensial menyebabkan tingkat pencemaran tersebut adalah polutan organik. Konsentrasi beberapa parameter kualitas air termasuk polutan organik di sungai Surabaya telah melebihi baku mutu air kelas I berdasarkan Peraturan Pemerintah (PP) No 82 tahun 2001, yakni untuk peruntukan air baku air minum. Tujuan dari penelitian ini adalah untuk melakukan peningkatan kualitas air baku seperti parameter padatan tersuspensi (TSS), zat organik, deterjen dan mangan (Mn) melalui penerapan teknologi biofilter. Penelitian dilakukan dengan mengoperasikan pilot plant biofilter yang terdiri dari bak pengendap tipe lamella dan reaktor biofilter yang diisi dengan media plastik tipe sarang tawon. Hasil penelitian menujukkan bahwa proses biofilter yang digunakan dapat menurunkan konsentrasi TSS, zat organik, deterjen dan Mn di dalam air baku. Secara umum semakin lama waktu tinggal di dalam pilot plant biofilter, efisiensi penghilangan TSS, zat organik, dan deterjen di dalam air baku semakin besar. Hasil percobaan pada kondisi total waktu tinggal terpendek (total HRT) 81 menit, meliputi HRT di bak pengendap 36 menit dan HRT di reaktor biofilter 45 menit, didapatkan efisensi penghilangan TSS 46,92 %, zat organik 15,97 %, dan deterjen 55 %, dimana konsentrasi parameter-parameter tersebut memenuhi baku mutu untuk air minum.Kata kunci: biofiltrasi, HRT, air minum, kualitas air

Abstract

ABSTRACTBedadung stream, located at Rambipuji, Balung, Wuluhan, and Puger, is downstream where dilution of organic wastes occurred and affects its water quality. Microorganisms decompose organic wastes and lead to depletion of dissolved oxygen in the water. The aim of this research was to analyze the deoxygenation rate of Bedadung downstream. The raw data was obtained by measuring stream flows and its water quality parameters (Temperature, DO and BOD) at 5 observed stations. The laboratory analysis consisted of BOD5 and long-term BOD2,4,6,8,10. Increasing the value of BOD for 10 days had a tendency of polynomial pattern order 3 with a coefficient of determination R 0.8987 – 0.9781. The 10 days BOD reactions were used to determine deoxygenation constant K (using least square method) with the result of ranged value 0.043 – 0.372 /day and Ultimate BOD 1.487 – 8.683mg/L. The values of deoxygenation rate at 5 stations were 0.182, 7.997, 7.236, 2.192, and 1.083 mg/L.day. The deoxygenation values were had a similar tendency with the amount of organic waste in the water column and its reduction rate due to the decomposition process.Keywords: Bedadung, BOD, Deoxygenation Rate, DOABSTRAKSungai Bedadung yang terletak di Kecamatan Rambipuji, Balung, Wuluhan dan Puger, merupakan sungai bagian hilir dimana zat pencemar organik bercampur, sehingga mempengaruhi kualitas perairan. Pencemar organik tersebut didekomposisi oleh mikroorganisme perairan sehingga menurunkan DO perairan. Tujuan penelitian ini adalah untuk mengkaji deoksigenasi Sungai Bedadung hilir. Data primer diperoleh dari pegukuran debit dan kualitas air (Temperatur, DO, dan BOD) di 5 (lima) titik pantau. Pengamatan BOD5 dan BOD2,4,6,8,10 dilakukan secara laboratorium. Peluruhan nilai BOD selama 10 hari cenderung memiliki tren polinomial dengan koefisien determinan berada pada nilai 0,8987 – 0,9781. Nilai peluruhan digunakan untuk menentukan nilai K (menggunakan metode least square) dan BOD ultimat. Nilai K di lima titik pantau menunjukkan rentang nilai 0,043 – 0,372 /hari dan BOD ultimat 1,487 – 8,683 mg/L. Sedangkan laju deoksigenasi di lima titik pantau menunjukkan nilai berturut-turut 0,182; 7,997; 7,236; 2,192; dan 1,083 mg/L./hari. Besar nilai deoksigenasi sangat ditentukan oleh banyaknya kandungan pencemar organik dalam air dan kecepatan reaksinya saat proses dekomposisi.Kata Kunci: Bedadung, BOD, Laju Deoksigenasi, DO

This process conducted at the optimum temperature of 370C. Indonesia, as a tropical country, has the potential for the application of anammox processes to remove nitrogen in wastewater. The purpose of this study was to analyze the efficiency of nitrogen removal in the anammox process using the Up-Flow Anaerobic Sludge Blanket (UASB) reactor at ambient temperature with variations in the hydraulic retention time (HRT) of 24 hours and 12 hours, at the laboratory scale. Samples are measured twice a week using a UV-Vis spectrophotometer. As a seeding sludge for start-up, the reactor was inoculated with granular anammox bacteria genus Candidatus Brocadia. At the stable operation, the ratio of ΔNO2--N:ΔNH4+-N and ΔNO3--N:ΔNH4+-N approach the stoichiometry of the anammox process were 1.20 and 0.21, respectively. The performance of nitrogen removal with 24-hour HRT obtained a maximum nitrogen removal rate (NRR) of 0.113 kg-N/m3.d with nitrogen loading rate (NLR) 0.14 kg-N/m3.d, and at 12-hour HRT, maximum NRR  of 0.196 kg-N/m3.d with NLR 0,28 kg-N/m3.d. Ammonium Conversion Efficiency (ACE) and Nitrogen Removal Efficiency (NRE) maximum for HRT 24 hours were 82% and 77%, respectively while HRT 12 hours were 72% and 68%, respectively. The anammox process operated stably in the tropical temperature with a temperature range of 23-280C on a laboratory scale using the UASB reactor.Keywords: anammox, nitrogen, temperature, tropical, uasb.ABSTRAKProses anammox menjadi alternatif yang lebih efektif dalam penyisihan nitrogen secara biologi dibandingkan dengan proses konvensional nitrifikasi-denitrifikasi.

ABSTRACTThis research was conducted to determine the status of Lake Toba water quality in the area of Toba Samosir (Tobasa) Regency and the feasibility of its use. This study revealed that BOD, COD, iron and free Cl2 of Lake Toba Tobasa regency exceed water quality criteria for Class I and Class II based on Governor Decree No. 1 Year 2009 on Raw water quality of Lake Toba in North Sumatera. High COD and BOD values imply that Lake Toba water was polluted by organic matter presumably originated from floating net cages (KJA), while free Cl2 is thought to originate from domestic waste activities in Parapat City and its surroundings. In general, it was concluded that the water of Lake Toba in the Tobasa Regency did not meet the criteria for clean water and water tourism.Keywords: Lake Toba, raw water, pollution, water qualityABSTRAKPenelitian ini dilakukan untuk mengetahui kualitas air Danau Toba wilayah Kabupaten Toba Samosir (Tobasa) dan kelayakan peruntukannya. Penelitian ini mengungkapkan bahwa air Danau Toba wilayah Kabupaten Tobasa memiliki BOD, COD dan konsentrasi besi dan Cl2 bebas melebihi kriteria mutu air Kelas I dan Kelas II pada Peraturan Gubernur Sumatra Utara No 1 Tahun 2009. Tingginya nilai COD dan BOD mengisyaratkan bahwa perairan Danau Toba tercemar oleh bahan organik yang diduga berasal keramba jaring apung (KJA), sedangkan Cl2 bebas diduga berasal dari limbah domestik kegiatan Kota Parapat dan sekitarnya. Secara umum disimpulkan bahwa air Danau Toba di wilayah Kabupaten Tobasa tidak/belum memenuhi kriteria untuk air baku air minum  dan wisata air.Kata kunci: danau Toba, bahan baku air, pencemaran, baku mutu

ABSTRACTPhosphorus (P) is a nutrient that is needed by plants. The availability of this element is greatly influenced by soil pH. As for ultisol soils classified as acid soils, most of the P in the soil is not available and is bound to Fe and Al. Pseudomonas, a phosphate solubilizing bacteria are soil microbes that can improve the availability of P in acid soils. This study aims to obtain Pseudomonas indigenous, a phosphate solubilizing bacteria from the acid soil formerly used by rubber plantations in the Institut Teknologi Sumatera. The study was conducted from April to June 2018 which included soil chemical analysis, isolation of the genus Pseudomonads on specific media, testing of phosphate solubility on solid Pikovskaya medium and simple pathogenicity test on potato tubers. The results showed that the sample soil was acidic with a pH of 4.09 with a P-availability of 0.78 ppm. From the soil samples, four potential isolates were obtained from the genus Pseudomonas, namely GSP 01, GSP 13, GSP 15 and GSP 06, with phosphate solubility indexes of 0.885, 0.639, 0.619 and 0.568, respectively. Isolates have the best phosphate solubilizing index on days 4 through 7. The four potential isolates are not pathogenic, so they can be used as isolates to improve the availability of soil nutrients, especially phosphorus needed by plants.Keywords: acid soil, phosphate solubilizing bacteria, phosphate availability, PseudomonasABSTRAKFosfor (P) merupakan unsur hara yang sangat dibutuhkan oleh tanaman.

Abstract

ABSTRACTNitrification is one of the most widely used methods to reduce ammonia concentration in wastewater.The purpose of this study was to determine the effectiveness of high-concentrated ammonia nitrification by the consortium between commercial probiotics and bacteria from the sediment of the catfish pond. The study was conducted on batch system bioreactors with a working volume of 1 liter containing 100 mg/L ammonia solution and 50 grams sediment of catfish pond. This study used a treatment variation of the concentration of commercial probiotics and the bacterial isolate from the catfish pond sediment using glucose as the carbon source. The variations of commercial probiotics added to the bioreactor were 5 ml/L, 10 ml/L and 15 ml/L. The variations of glucose concentration were 0 g/L and 3,9 g/L. Analysis of ammonia concentration was carried out by spectrophotometry using the phenate method. The highest removal efficiency of ammonia was 92.35% in the bioreactor with a mixture of 15 ml/L commercial probiotics and 3.9 g/L glucose with the fastest ammonia rate was on the third day of the experimental period. The addition of glucose in the bioreactors could increase ammonia removal by 57.39%. The result of statistical analysis indicated that variations in the concentration of commercial probiotic indicated no statistically significant difference in ammonia removal (P> 0.05), while variations in glucose concentration showed a statistically significant difference in ammonia removal (P <0.05). Three isolates were successfully isolated on specific media for nitrifying bacteria. The result of bacterial identification showed that three isolated bacteria were Bacillus sp., Aeromonas salmonicida, and Burkholderia cepacia.Keywords: ammonia, nitrification, sediment of catfish pond, commercial probioticABSTRAKNitrifikasi merupakan salah satu metode yang paling banyak digunakan untuk mengurangi konsentrasi amonia pada limbah cair.
