Abstract

ABSTRACTWater treatment plants (WTPs) produces residues in the form of alum sludge during the treatment process. In Indonesia, due to various techno-economic constraints, some WTPs are not equipped by sludge treatment systems, so the generated alum sludge is discharged directly into water bodies without appropriate treatment. This condition may pollute water bodies because alum sludge contains various contaminants such as solid particles, organic compounds, inorganic metals, aluminum, and pathogenic microorganisms. This study aims to evaluate the characteristics of alum sludge from aspects of quality and quantity, which is indispensable for the design of sludge treatment facilities. Citayam WTP (capacity of 120 L/s) in Depok City was chosen as a case study. The study was conducted in several stages as follows: (i) survey and sampling; (ii) quality analysis of alum sludge; (iii) estimation of sludge generation; and (iv) mass and volume balance analysis. Results of comparative analysis of alum sludge quality against the Regulation of Minister of Environment of Indonesia 5/2014 shows alum sludge from flocculation units meets quality standards. In contrast, alum sludge from sedimentation and filter units were exceeded for TSS, COD, and Total Coliform parameters. Quantity-wise, the estimation of sludge generation by theoretical and empirical methods was found to be 1,898 kg/day and 4,854 kg/day. Analysis of mass and volume balance using STAN software indicates that the theoretical approach is quite representative, while the empirical method tends to be over-estimated.Keywords: alum sludge, sludge quality, sludge generation, water treatment plant, case studyABSTRAKInstalasi pengolahan air (IPA) dalam proses pengolahannya akan menghasilkan residu berupa lumpur alum. Di Indonesia, akibat berbagai kendala tekno-ekonomis, masih terdapat IPA yang belum memiliki sistem pengolahan lumpur alum sehingga langsung dibuang ke badan air tanpa pengolahan. Kondisi ini berpotensi mencemari badan air karena lumpur alum mengandung berbagai kontaminan seperti partikel padat, senyawa organik, inorganik, logam aluminium serta mikroorganisme patogen. Penelitian ini bertujuan untuk mengevaluasi karakteristik lumpur alum dari aspek kualitas dan kuantitas yang merupakan informasi penting dalam perancangan sistem pengolahan lumpur. IPA Citayam (Kapasitas 120 L/detik) di Kota Depok dipilih sebagai objek studi. Penelitian dilakukan dalam beberapa tahapan yakni survei dan sampling, analisis kualitas lumpur alum, estimasi timbulan lumpur, dan analisis neraca massa dan volume. Hasil perbandingan analisis kualitas lumpur alum terhadap PermenLH 5/2014 menunjukan lumpur alum dari unit flokulasi memenuhi baku mutu sedangkan lumpur alum dari unit sedimentasi dan filter melebihi baku mutu lingkungan untuk parameter TSS, COD dan Total Koliform. Dari aspek kuantitas, estimasi timbulan lumpur yang dilakukan dengan metode teoritik dan empirik berturut-turut sebesar 1.898 kg/hari dan 4.854 kg/hari. Analisis neraca massa dan volume menggunakan software STAN mengindikasikan bahwa metode teoritik cukup representatif, sedangkan perhitungan dengan metode empirik cenderung menjadi over-estimasi.Kata kunci: lumpur alum, kualitas lumpur, timbulan lumpur, instalasi pengolahan air, studi kasus

Abstract

ABSTRACTIn order to create a city clean, efforts are taken by the government, including the provision of waste processing system facilities as part of a waste management system. Recently, Klungkung Regency, Bali Province, has three alternatives waste processing systems to be applied, namely: utilizing the existing regional final disposal site (TPA) of Bangli, building a new TPA facility dedicated to Klungkung area only, and communal waste processing facility. The study aims to determine the most optimal waste processing system by considering four criteria (multicriteria) with the Analytical Hierarchy Process (AHP) from 35 respondents representing five local government institutions. Among the criteria, environment (weight of 0.543) was more prioritized than social (0.181), financial (0.146) and technical (0.130) aspects. Respondents preferred to put environmental pollution prevention (weight of 0.16) as the most important among 13 sub-criteria. Other results showed that TOSS (total value of 0.47) was more preferred than the existing TPA of Bangli (0.28) and new the TPA of Klungkung (0.25). An alternative waste processing with its advantages and disadvantages should be chosen and acceptable by the related stakeholders. Thus, the facility becomes part of a sustainable waste management system in a city.Keywords: multicriteria analysis, pair wise comparison, analytical hierarcy process, waste processing systemABSTRAKBerbagai macam upaya dilakukan oleh pemerintah untuk menciptakan lingkungan suatu kota yang bersih, diantaranya melalui penyediaan fasilitas sistem pemrosesan sampah sebagai tahapan akhir dalam pengelolaan sampah.

Abstract

ABSTRACTThe anammox process plays an essential role in removing nitrogen from the waters anaerobically. Since the discovery of anammox in 1995, no studies have reported anammox bacteria from the Indonesian environment. This research aims to begin exploring anammox bacteria from the environment in Indonesia as a tropical country. The exploration was carried out with a start-up anammox process in a continuous reactor. The reactor was constructed using a housing filter equipped with a string wound filter as a supporting media for biofilm. Sludge from Koto Baru Lake, Tanah Datar, Indonesia, was used as inoculum. The substrate was fed into the reactor through the inside of the filter using a peristaltic pump. Ammonium and nitrite were supplemented to the substrate at a 70-150 mg-N/L concentration and operated at room temperature. The samples were collected once a week. Ammonium and nitrite were measured using the colorimetric method, nitrate using the ultraviolet spectrophotometric method. Performance of nitrogen removal and the growth biofilm in the reactor shown the success of the start of the anammox process. After 140 days of reactor operation, the maximum value of nitrogen removal rate (NRR) was 0.271 kg-N/m3.day at the nitrogen loading rate (NLR) 0.3095 kg-N/m3.day. Ammonium conversion efficiency (ACE) and nitrogen removal efficiency (NRE) during start-up were 97.07% and 91.92%. Red biofilm growth on the filter and the reactor's inner wall, which is characteristic of the anammox bacteria biomass.Keywords: anammox, Indonesia, Koto Baru Lake, tropical   ABSTRAKProses anammox memiliki peran penting dalam penyisihan nitrogen dari perairan secara anaerobik.

ABSTRACTThe Bukit Ameh (Mandeh) area of Pesisir Selatan Regency, West Sumatra, has a potentially unique landscape as a tourist attraction. Therefore, this area will be developed into a special economic area for tourism. However, for doing so, there will be various activities performed there that could affect the environmental conditions there. Accordingly, this study was carried out to determine the quality status of the Bukit Ameh coastal waters to anticipate the impact of various special economic areas for tourism development activities in the future. This study's results indicate that the nutrient content of Bukit Ameh waters has exceeded the Quality Standards. The coastal waters of Bukit Ameh, inhabited by 23 species of phytoplankton from 4 classes with abundance ranging from 795,183 to 3,909,750 ind/m3. Phytoplankton community is dominated by Trichodesmium sp. with the highest population of 2,162,994 ind/m3 or 73.2 percent of total abundance. In addition to Trichodesmium sp., on the coast of Bukit Ameh also found Ceratium sp., Dinophysis sp., and Peridinium sp., which can trigger the Harmful Algal Bloom which is poisonous and can kill other organisms that eat it. Comparing dissolved nutrients and abundance of phytoplankton in several coastal does not show a positive correlation, in the sense that the more fertile the waters, the higher the abundance of phytoplankton.Keywords: water quality, coastal, abundance, phytoplanktonABSTRAKKawasan Bukit Ameh (Mandeh) Kabupaten Pesisir Selatan, Sumatra Barat,  merupakan salah satu kawasan pariwisata yang memiliki keunikan bentang alam sebagai daya tarik wisata, sehingga kawasan ini akan dikembangkan menjadi Kawasan Ekonomi Khusus (KEK) Pariwisata. Terkait hal ini, akan ada kegiatan pengembangan ekonomi yang memiliki potensi mempengaruhi kondisi lingkungan di sana.

Abstract

ABSTRACT Health risk characteristics expressed as a Risk Quotient (RQ) can be carried out through an environmental health risk analysis (ARKL) approach. This approach can estimate the public health risk caused by the concentration of risk agents of particulates consisting of PM2.5, PM10, and TSP. The research on the fluctuation of ambient air particulate pollutant and its risk to public health was conducted in each sub-district of Bogor City. Author identified a total of 360 respondents to determine the community anthropometric variable of exposures for time, frequency, and duration. There are several steps that need to be carried out to obtain the RQ value, namely identification of hazards from particulate risk agents, analysis of the dose-response in the form of Reference Concentration (RFC), analysis of the exposure obtained based on anthropometric variables, and the concentration of risk agents as well as characteristics of risk levels. The risk level characteristic shows that the RQ value of TSP is always the highest one, followed by PM10 and PM2.5. The respective RQ values of TSP for male and female residents are 1.85 and 1.53. Cumulatively, the male and female population in Tanah Sareal produced the highest RQ values. Those are 4.44 and 3.36, respectively. At the same time, the lowest cumulative RQ was obtained for male and female residents in East Bogor with RQ values of 2.96 and 2.54. The RQ value of each risk agent or the cumulative RQ that is more than 1 (RQ> 1) is stated to have or has a health risk, so it needs to be controlled, while the RQ value which is less than one (1) is displayed not to need to be controlled but needs to be maintained. Keywords: particulate, risk level, exposure assessment, anthropometric characteristic, environmental health risk assessment   ABSTRAK Karakteristik risiko kesehatan yang dinyatakan sebagai Risk Quotient (RQ) dapat dilakukan melalui pendekatan Analisis Risiko Kesehatan Lingkungan (ARKL). Pendekatan ini dapat mengestimasi risiko kesehatan masyarakat yang disebabkan oleh konsentrasi agen risiko yaitu PM2,5, PM10, dan TSP di tiap-tiap kecamatan di Kota Bogor. Penulis mengidentifikasi sebanyak 360 responden yang terdiri dari laki-laki dan perempuan untuk menentukan variabel antropometri masyarakat di Kota Bogor, waktu paparan, frekuensi paparan, serta durasi paparan. Ada beberapa tahapan yang perlu dilakukan untuk memperoleh nilai RQ, yaitu identifikasi bahaya dari agen risiko partikulat, analisis dosis-respon berupa Reference Concentration (RfC), analisis pajanan yang diperoleh berdasarkan variabel antropometri dan konsentrasi agen risiko serta karakteristik tingkat risiko. Karakteristik tingkat risiko menunjukkan nilai RQ TSP selalu paling tinggi diikuti PM10, dan terendah adalah RQ PM2,5 dengan nilai tertinggi TSP untuk penduduk laki-laki dan perempuan masing-masing sebesar 1,85 dan 1,53. Secara kumulatif, penduduk laki-laki dan perempuan di Tanah Sareal menghasilkan nilai RQ tertinggi masing-masing sebesar 4,44 dan 3,36. Sedangkan RQ kumulatif terendah diperoleh untuk penduduk laki-laki dan perempuan di Bogor Timur dengan nilai RQ 2,96 dan 2,54. Nilai RQ tiap agen risiko ataupun RQ kumulatif yang lebih dari 1 (RQ>1) dinyatakan memiliki atau terdapat risiko kesehatan sehingga perlu dikendalikan, sementara nilai RQ yang masing kurang dari satu dinyatakan tidak perlu dikendalikan tetapi perlu dipertahankan. Kata kunci: partikulat, tingkat risiko, analisis pajanan, karakteristik antropometri, analisis risiko kesehatan lingkungan
