Abstract

Hybrid Anaerobic Baffled Reactor (ABR)-Biofilter didesain untuk mengolah limbah dengan beban organic tinggi dan untuk lahan sempit. Apartemen dipilih, karena limbahnya berasal dari manusia, usaha laundry dan restaurant, yang menghasilkan limbah dengan beban organik tinggi dan memiliki keterbatasan lahan pengolah limbahnya. Penelitian ini bertujuan untuk mengevaluasi kemmpuan reactor hybrid Anaerobic Baffled Reactor (ABR) dan Biofilter.  Penelitian ini dilakukan dengan menggunakan reaktor skala laboratorium dengan total volume efektif 60,72 L, terdiri dari tiga kompartemen ABR dan dua kompartemen biofilter. Kinerja reactor dinilai berdasarkan variasi konsentrasi dan debit influen air limbah. Bioball digunakan dalam reaktor biofilter sebagai media lekat untuk pertumbuhan mikroba. Reaktor mampu mendegradasi zat organik dengan persentase penyisihan tertinggi. Hasil penelitian menunjukkan bahwa konsentrasi kontaminan organik yang diolah lebih tinggi, terutama pada total nitrogen dan fosfor.

Abstract

Pabrik pupuk merupakan salah satu industri yang menghasilkan air limbah dengan konsentrasi amonium tinggi yang jika dibuang langsung ke lingkungan akan membahayakan kehidupan di perairan. Sejauh ini pengolahan limbah pabrik masih menggunakan proses steam stripping dan wetland. Anammox merupakan bioteknologi untuk pengolahan air limbah dengan rasio karbon/nitrogen (C/N) yang rendah. Penelitian ini bertujuan untuk menganalisis penyisihan nitrogen menggunakan lumpur dari instalasi pengolahan air limbah pabrik pupuk sebagai inokulum dalam proses anammox. Penelitian menggunakan reaktor yang terdiri dari housing filter dan string wound filter sebagai media lekat biomassa yang dinamakan Filter Bioreactor (FtBR). FtBR yang sudah diisi dengan inokulum dari lumpur limbah pabrik pupuk dialiri substrat secara kontinu dengan konsentrasi amonium dan nitrit 70 mg-N/L, HRT 24 jam dan dioperasikan selama 120 hari pada suhu 35oC. Efisiensi penyisihan nitrogen dihitung dengan menguji konsentrasi amonium, nitrit dan nitrat menggunakan spektrofotometer UV-Vis. Kinerja penyisihan nitrogen dengan parameter ammonium conversion efficiency (ACE), nitrogen removal efficiency (NRE) dan removal rate (NRR) adalah 88,01%, 85.85%, 0.141 kg-N/m3.h, pada nitrogen loading rate (NLR) 0.144 kg-N/m3.h.

Abstract

AbstractReduced tourism is one of the unintended consequences of garbage accumulation in popular tourist destinations. There are both internal and external elements that influence people's willingness to participate in managed waste. The purpose of this research is to identify the external elements in the coastal community of Teluk Turtle Cilacap that influence inhabitants' involvement in garbage management. Methods included conducting in-depth interviews with 204 eligible beachgoers in the Teluk Penyu area and collecting data through observation and questionnaires. This research found that 42.1% of the variation in people involvement in controlling Teluk Turtle beach garbage was attributable to five factors: community leaders, information, incentives, local institutional capabilities, and infrastructure. Citizens' engagement in waste management is most directly influenced by incentives and community leaders and least by the local community's access to relevant knowledge, resources, and infrastructure. Unlike the knowledge variable, which can entirely mediate the relationship between community leaders, facilities, and the competency of local institutions and participation, the incentive variable can fully mediate the relationship between facilities and participation. As this research shows, environmental factors have a substantial impact on waste management involvement among Teluk Turtle people. The study's findings can be utilized as a guide for enhancing coastal trash management by highlighting the importance of the relationship between the variables investigated.

Abstract

The relationship between parameters in wetlands, especially peatlands, as a part of the analysis is interesting to study. The analysis is expected to show the condition of the peatland or the state of the wetlands in general. The water table elevation (WTE) is measured daily, so to compare it with evapotranspiration and rain, daily values for these two parameters are also required. The study was conducted between June-July and August 2022 on shallow peatlands in Gambut District, Banjar Regency, South Kalimantan Province. Evapotranspiration in this study was calculated using the Hargreaves and Modified Hargreaves method which presents a daily evapotranspiration calculation. The methods only depend on the maximum and minimum temperature, the number of outer space radiation whose magnitude depends on its location on the earth's surface, and the time when the research is conducted. The results showed that the highest daily evapotranspiration value generally occurred in August, which was in accordance with previous studies, but the magnitudes were different. The daily evapotranspiration value in this study ranged from 0.5 mm to 1.8 mm, while previously, the values were greater. WTE values show a strong relationship with rainfall, where rainfall increases the WTE value, and conversely, the absence causes the WTEs to decrease gradually. In general, the condition of the peatlands in the study area based on the groundwater elevation conditions still looks quite good with a fast response to rain. The relationship of evapotranspiration with rain and water table elevation cannot be clearly seen in this study because alterations in rainfall and WTE do not directly indicate changes in evapotranspiration values, so a more extended study covering other months and more in-depth covering parameters and other methods is needed to draw valid conclusions more accurate.

Abstract

This research was conducted along a tributary that empties into the Opak River in Piyungan District. This study aimed to examine the characteristics of leachate from the Piyungan landfill, river water quality, and the status of river water quality due to the discharge of leachate from the Piyungan landfill. The research method used is a survey method with sampling and field observations. Purposive sampling is used to take river sample points. There are five sample points taken with 15 test parameters used to analyze river water quality, including COD, BOD, TSS, TDS, Zinc (Zn), Iron (Fe), Chromium, Copper (Cu), Lead (Pb), Mercury (Hg), pH, temperature, turbidity, color, and total coliform. River water quality status is obtained by calculating the Pollution Index (IP) of class II quality standard, Governor of DIY Regulation Number 20 of 2008, without the total coliform parameter. Based on the analysis results, the characteristics of the leachate water of the Piyungan TPA have concentrations of BOD, COD, TSS, TDS, and Iron (Fe), which exceed the quality standards of Yogyakarta Special Region Regulation Number 7 of 2016. River water quality shows that parameters BOD, COD, TSS, TDS, Zinc (Zn), Iron (Fe), turbidity, color, and total coliform exceed class II water quality standards regulation of the Governor of the Special Region of Yogyakarta Number 20 of 2008. The highest pollution load in rivers is Total Coliform, BOD, and COD. The status of river water quality from all sample point locations has the status of heavily polluted water (Point S1), moderately polluted (Point S2, S3, S4), and lightly polluted (Point S5). Thus, river water quality around the Piyungan landfill has decreased due to the discharge of leachate from the Piyungan landfill and community activities around the river.

Abstract

ABSTRAKDebit puncak aliran sungai Ciliwung bagian hulu dalam periode ulang tertentu merupakan informasi yang sangat penting dalam perencanaan pengendalian banjir maupun pemanfaatan sumberdaya air. Debit puncak aliran sungai utama tersebut dipengaruhi oleh debit aliran sungai dari setiap subDAS yang masuk ke sungai utama. Namun, Stasiun Pengamat Arus Sungai (SPAS) sebagai  sarana pengukur debit tidak tersedia di setiap Sub DAS. Tujuan penelitian ini adalah mengkaji akurasi Model Rasional dalam memprediksi debit puncak dan melakukan pendugaan debit puncak pada tiap Sub DAS Ciliwung Hulu. Pendugaan debit puncak dilakukan dengan metode Rasional menggunakan distribusi peluang.  Hasil penelitian menunjukkan bahwa prediksi debit puncak menggunakan metode Rasional dengan periode ulang T1 hingga T10 tahun memiliki  akurasi yang baik dengan R2 = 0,98 dan Nash-Sutcliffe Efficiency (NSE) = 0,14 pada distribusi Gumbel, sementara pada distribusi Log Pearson tipe III dengan R2 = 0,99 dan NSE = 0,86. Dengan demikian, model Rational dengan distribusi Log Pearson tipe III lebih layak digunakan sebagai prediksi debit puncak pada periode ulang T1 hingga T10, T25, T50 dan T100 tahun. Selanjutnya model Rational dengan distribusi Log Pearson tipe III  dapat digunakan untuk memprediksi debit puncak aliran sungai di tiap sub DAS Ciliwung Hulu, yaitu Sub DAS Cibalok, Ciesek, Ciliwung Hulu, Cisarua, Ciseuseupan, Cisukabiru, dan Cisuren. Berdasarkan pendugaan dengan metode Rational, nilai debit puncak prediksi terendah pada periode ulang 1 tahun terjadi di Sub DAS Cibalok sebesar 8,67 m³/detik dan tertinggi di Sub DAS Ciliwung Hulu sebesar 42,16 m³/detik.   Data prediksi debit puncak dari tiap subDAS Ciliwung hulu ini dapat menjadi informasi yang sangat penting dalam pengendalian sumberdaya air di DAS Ciliwung Hulu.Kata kunci: Debit puncak, distribusi Gumbel, distribusi Log Pearson Tipe III, metode Rasional, periode ulangABSTRACTThe peak discharge of the Upstream Ciliwung in certain period is very important information in flood control planning and utilization of water resources. The peak discharge of the main river is influenced by the discharge of the river flow from each sub watershed that enters the main river. However, the Stream Flow Observer Station (SPAS) as a means of measuring discharge  in every sub-watershed is not available. The purpose of this study was to examine the accuracy of the Rational Model in predicting peak discharge in each of the Upper Ciliwung Sub-Watershed.  The Peak discharge estimation was carried out using the Rational method with a probability distribution.  The result showed that the prediction of peak discharge using the Rational method with a return period of T1 to T10 years had a good accuracy with R2 = 0,98 and Nash-Sutcliffe Efficiency (NSE) = 0,14 in the Gumbel distribution, while in the Log Pearson type III distribution with R2 = 0,99 and NSE = 0,86.  Thus, the Rational model with Log Pearson Type III distribution is more suitable to be used as a prediction of peak discharge in the return period T1 to T10, T25, T50, and T100 years.  Furthermore, the Rational model with the Log Pearson distribution Type III can be used to predict the peak discharge of the stream flow in each of the Upper Ciliwung  Sub-Watershed, namely the Cibalok, Ciesek, Ciliwung Hulu, Cisarua, Cisesuseupan, Cisukabiru, and Cisuren.  Based on the estimation using the Rational method, the lowest predicted peak discharge value in the 1-year return period occurs in the Cibalok Watershed at 8.67m3/second and the hihgest in the Ciliwung Hulu Watershed at 42.16 m3/second.  The predicted peak discharge data from each upstream Ciliwung sub-Watershed can be very important information  for  controlling water resources in the Upper Ciliwung Watershed.Keyword: Gumbel distribution, Log Pearson Type III distribution, Peak discharge, Rational method, return Period.
