Abstract

ABSTRAK Penurunan kinerja IPAL komunal di Kabupaten Sleman terjadi di beberapa lokasi, salah satunya di IPAL komunal Ngudi Saras. Air hasil pengolahan dari IPAL komunal ini menurut data uji kualitas air Dinas Lingkungan Hidup Kabupaten Sleman memiliki beberapa parameter yang tidak sesuai dengan baku mutu Peraturan Menteri Lingkungan Hidup dan Kehutanan Republik Indonesia Nomor 68 Tahun 2016 Tentang Baku Mutu Air Limbah Domestik yaitu: BOD, COD, dan amonia total. Tujuan penelitian ini adalah membuat perancangan unit filtrasi sebagai rehabilitasi yang dilakukan berdasarkan data efektivitas kinerja IPAL komunal Ngudi Saras. Metode penelitian yang digunakan adalah metode kuantitatif dengan melakukan perhitungan evaluasi standar effluent terhadap hasil uji kualitas air limbah pada parameter BOD, COD, dan amonia total. Penelitian ini menggunakan dua macam data, yaitu data primer dan sekunder untuk bahan pada penelitian ini. Sampel air diambil di 4 titik pada IPAL komunal dan 3 titik pada sungai. Didapatkan hasil bahwa parameter amonia total pada perhitungan evaluasi standar effluent masih perlu dilakukan reduksi sebesar 67.4742%. Dengan amonia total yang masih perlu dilakukan reduksi, maka perlu dilakukan pengelolaan berupa rehabilitasi IPAL komunal Ngudi Saras dengan penambahan unit filtrasi. Sehingga jika parameter amonia total telah tereduksi maka air buangan dari IPAL komunal Ngudi Saras tidak akan mencemari lingkungan. Kata kunci: amonia total, BOD, COD, filtrasi, IPAL komunal, rehabilitasi  ABSTRACT The decline in the performance of communal wastewater treatment plants (IPAL) in Sleman Regency is occurring at several locations, including the Ngudi Saras communal IPAL. According to water quality test data from the Sleman Regency Environmental Agency, the treated water from this communal IPAL does not meet the standards set by the Minister of Environment and Forestry of the Republic of Indonesia Regulation Number 68 of 2016 regarding Domestic Wastewater Quality Standards, specifically for BOD, COD, and total ammonia parameters. The objective of this study is to design a filtration unit as part of the rehabilitation based on the performance data of the Ngudi Saras communal IPAL. The research method used is quantitative method by conducting standard effluent evaluation calculations for the test results of wastewater quality on parameters such as BOD, COD, and total ammonia. This study utilizes two types of data, namely primary and secondary data, as the basis for the research. Water samples were collected from four points within the communal IPAL and three points along the river. The water test results were then used to calculate the standard effluent evaluation. The findings indicate that the total ammonia parameter in the standard effluent evaluation calculation still requires a reduction of 67.4742%. Given the need for a reduction in total ammonia, it is necessary to manage the rehabilitation of the Ngudi Saras communal IPAL through the addition of a filtration unit. This way, once the total ammonia parameter has been reduced, the effluent from the Ngudi Saras communal IPAL will not pollute the environment. Keywords: total ammonia, BOD, COD, filtration, Communal WWTP, rehabilitation

Abstract

ABSTRAK Pencemaran air oleh logam berat terjadi akibat perkembangan industri seperti tekstil, electroplating, dan penyamakan kulit. Kromium (Cr) merupakan salah satu logam berat yang dihasilkan dengan tingkat toksisitas tinggi bagi makhluk hidup bahkan dalam konsentrasi rendah. Upaya penanggulangan yang ramah lingkungan dilakukan dengan metode bioremediasi dapat memanfaatkan kemampuan bakteri resisten logam berat. Penelitian ini bertujuan untuk mengisolasi, mengidentifikasi, dan melakukan uji potensi reduksi logam berat kromium oleh bakteri laut resisten kromium. Penelitian ini menggunakan bahan sampel air laut, pasir Pantai Samas dan Pantai Pandansimo, media kultur Zobell marine broth 2216, serta logam berat K2Cr2O7. Langkah awal penelitian dilakukan dengan pengambilan sampel air laut dan pasir pantai. Selanjutnya dilakukan isolasi, seleksi, karakterisasi morfologi sel dan biokimia serta identifikasi bakteri resisten kromium untuk diuji potensi reduksinya. Hasil tiga isolat terseleksi memiliki kemampuan resistensi tertinggi terhadap kromium. Proses identifikasi menunjukkan bahwa dua isolat, yaitu PSAA1 dan SMCS21 diduga merupakan anggota genus Proteus, sedangkan satu isolat PSAA8 diduga merupakan anggota genus Micrococcus. Ketiga isolat bakteri PSAA8, SMCS21, dan PSAA1 menunjukkan kemampuan reduksi kromium dengan efisiensi reduksi secara berurutan sebesar 22.54%, 21.54%, dan 18.44%. Sehingga ketiga isolat bakteri laut disimpulkan memiliki potensi sebagai agen bioremediasi untuk mengurangi konsentrasi logam berat kromium dari lingkungan perairan. Kata kunci: Bakteri Laut, bioremediasi, kromium, Micrococcus, Proteus ABSTRACT Water pollution by heavy metals occurs as a result of industrial developments such as textiles, electroplating and leather tanning. Chromium (Cr) is one of the heavy metals that is produced with a high level of toxicity to living things even in low concentrations. Environmentally friendly countermeasures carried out by the bioremediation method can utilize the ability of heavy metal resistant bacteria. This study aims to isolate, identify, and test the potential reduction of chromium heavy metal by chromium-resistant marine bacteria. This study used seawater samples, sand from Samas Beach and Pandansimo Beach, culture media Zobell marine broth 2216, and heavy metal K2Cr2O7 solution. The initial step of the research was carried out by taking samples of seawater and beach sand. Furthermore, isolation, selection, morphological, cell and biochemical characterization were carried out as well as identification of chromium resistant bacteria to test their reduction potential. The results of the three selected isolates had the highest resistance ability to chromium. The identification process showed that two isolates, namely PSAA1 and SMCS21 were suspected to be members of the genus Proteus, while one isolate PSAA8 was suspected to be a member of the genus Micrococcus. The three bacterial isolates PSAA8, SMCS21, and PSAA1 showed the ability to reduce chromium with reduction efficiencies of 22.54%, 21.54%, and 18.44% respectively. So that the three marine bacterial isolates were concluded to have potential as bioremediation agents to reduce the concentration of the heavy metal chromium from the aquatic environment. Keywords:  Bioremediation, chromium, marine Bacteria, Micrococcus, Proteus

Abstract

ABSTRAK Pengelolaan sampah secara open dumping dapat menimbulkan dampak buruk bagi lingkungan. Salah satunya adalah air lindi, yang dihasilkan dari dekomposisi sampah akibat terjadinya presipitasi air hujan ke dalam sampah. Air lindi dapat mengandung zat berbahaya seperti logam berat, salah satunya timbal (Pb), yang bersifat karsinogenik serta dapat mencemari udara, air, tanah, tumbuhan, dan hewan. Oleh karena itu, perlu dilakukan pengelolaan lindi dengan metode yang tepat agar tidak mencemari lingkungan, salah satunya menggunakan bioremediasi dengan memanfaatkan mikroorganisme indigenous dari tempat asal polutan. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi bakteri indigenous yang mempunyai kemampuan dekontaminasi timbal (Pb) dari TPST Piyungan. Bakteri diisolasi dari air lindi menggunakan medium nutrient broth dan nutrien agar yang telah ditambahkan timbal dari Pb(NO3)2. Isolat yang didapatkan kemudian dilakukan seleksi dan skrining untuk mendapatkan beberapa isolat terbaik yang resisten timbal. Daya penurunan konsentrasi timbal diukur menggunakan Atomatic Absorption Spectrophotometer (AAS). Isolat bakteri juga diidentifikasi karakter fenotopik berupa morfologi sel, morfologi koloni, dan sifat fisiologisnya untuk menentukan jenis bakteri yang diteliti. Berdasarkan proses isolasi dan skrining, didapatkan tiga isolat yang resisten timbal dengan daya reduksi yang cukup tinggi 67.13%, 40.89%, dan 14.65%. Ketiga isolat berasal dari genus yang berbeda, meliputi Serratia, Proteus, dan Thiobacillus. Kata kunci: bakteri indigenous, bioremediasi, dekontaminasi, timbal ABSTRACT Waste management by open dumping can have a negative impact on the environment. One of them is leachate, which is produced from the decomposition of waste due to precipitation of rainwater into the waste. Leachate can contain harmful substances such as heavy metals, one of which is lead (Pb), which is carcinogenic and can contaminate air, soil, plants, and animals. Therefore, it is necessary to manage leachate with the right method so as not to damage the environment, one of which is using bioremediation by utilizing native microorganisms from pollutant origins. This study aims to isolate and identify indigenous bacteria that can decontaminate lead (Pb) from Piyungan TPST. Bacteria were isolated from leachate using nutrient broth and nutrien agar medium which had been added with lead from Pb(NO3)2. The isolates obtained were then selected and screened to obtain the best lead-resistant isolates. The reduction power of lead concentration was measured using an Atomic Absorption Spectrophotometer (AAS). Bacterial isolates also identified phenotopic characters in the form of cell morphology, colony morphology, and physiological characteristics to determine the type of bacteria. Based on the isolation and screening process, three lead-resistant isolates were obtained with relatively high reducibility of 67.13%, 40.89% and 14.65%. The third isolate came from a different genus, including Serratia, Thiobacillus, and Bacillus. Keywords: indigenous bacteria, bioremediation, decontamination, lead

Abstract

 Population growth affects the generation of plastic waste and could potentially increase greenhouse gas (GHG) emissions through the burning process. This has become a severe problem as it contributes to global warming. Therefore, plastic waste management is required, for instance, by using pyrolysis technology on a community scale. Such a project will reduce plastic waste and GHG emissions by processing plastic into valuable products. This study aims (1) to estimate potential GHG emissions before the project implementation, (2) to estimate potential GHG emissions reduction after the project implementation, and (3) to assess both potential revenue and profit of pyrolysis products. This study employs SNI 19-3694-1994 method to estimate household waste generated, the clean development mechanism (CDM) method to estimate GHGs emissions reduction, and the profit comparison method (PCM) to asses both revenue and profit of pyrolysis products. The results show that GHG emissions before the project will be 3.69 t CO2e in 2021 and could increase to 4.61 t CO2e in 2030. Potential GHG emissions reduction depends on the fuel types to heat the reactor. Only electric pyrolysis will reduce GHG emissions by up to 0.46 t CO2e (13%) annually. This project is not financially feasible because operational costs (15,772,779 IDR) exceed the annual revenue (1,014,000 IDR).Keywords: CDM, climate change, GHG emission, plastic waste, pyrolysis

Abstract

Mangrove degradation in Bandar Lampung, specifically Kota Karang, Teluk Betung Timur, has left only 9,86% or 6 hectares, causing habitat loss and increased greenhouse gas emissions. This study identifies deficiencies in the government-led mangrove management system, emphasizing individual management leading to overlapping responsibilities and a lack of coordination. The research method employed is descriptive qualitative, incorporating primary data from observations, interviews, and documentation, alongside secondary data and literature studies. Observations encompass the assessment of biophysical elements, ecological indicators, and mangrove reduction due to land conversion. Literature studies focus on identifying soil types, water pH, dissolved oxygen levels, mangrove vegetation types, and principles of integrated landscape management. SWOT (Strength, Weakness, Opportunity, Threats) analysis considers stakeholders roles, disaster risks, land conversion, pollution, over-exploitation, and community participation. Findings prompt five strategies: community empowerment, eco-friendly tourism, cross-sector cooperation, enhanced monitoring, and mangrove rehabilitation. Recommendations, rooted in integrated landscape management, target all stakeholders, with a focus on government involvement. This holistic approach addresses identified issues, striving for enhanced mangrove ecosystem sustainability through collaborative efforts and strategic planning, emphasizing the need for coordinated stakeholders action in mangrove conservation. Keywords:  degradation, land conversion, stakeholders, SWOT analysis.
