Abstract

ABSTRAK Ranu Pani merupakan objek wisata berupa danau di desa Ranu Pani di kecamatan Senduro, Kabupaten Lumajang, Jawa Timur yang merupakan bagian dari Taman Nasional Bromo Tengger Semeru (TNBTS). Kegiatan warga di bidang pertanian merupakan salah satu faktor terjadinya penyempitan di Danau Ranu Pani. Perubahan karakteristik lahan dan intensitas curah hujan yang cukup tinggi serta perubahan penggunaan lahan juga merupakan faktor yang ikut berperan dalam munculnya erosi. Mengetahui besarnya erosi yang terjadi di suatu wilayah merupakan hal yang penting, karena selain dapat mengetahui banyaknya tanah yang tererosi juga dapat digunakan sebagai salah satu jalan untuk mencari sebuah solusi dari permasalahan tersebut. Penelitian ini menggunakan metode USLE dan metode petak kecil untuk menghitung erosi yang terjadi pada lahan pertanian kubis dan kentang yang berukuran ¼ hektar. Petak kecil yang digunakan berukuran 4x2 meter yang berada pada topografi curam (25-40%). Metode ini digunakan untuk validasi terhadap perhitungan USLE dengan catatan jenis tanah dan kemiringan tanahnya sama. Pengukuran menggunakan petak kecil dilakukan selama 1 bulan setiap kejadian hujan. Pada metode petak kecil di lahan campuran kubis dan kentang diperoleh nilai erosi sebesar 21.27 ton.ha-1.tahun-1, sedangkan metode USLE sebesar 74.23 ton.ha-1.tahun-1. Berdasarkan hasil dari pehitungan tersebut, lahan pertanian ini memiliki klasifikasi berat pada metode USLE dan sedang pada metode petak kecil. Kata kunci: Desa Ranu Pani, erosi, petak kecil, Taman Nasional Bromo Tengger Semeru (TNBTS), USLE ABSTRACT Ranu Pani is a tourist attraction in the form of a lake in Ranu Pani village in Senduro sub-district, Lumajang Regency, East Java which is part of the Bromo Tengger Semeru National Park (TNBTS). Residents' activities in agriculture are one of the factors causing the narrowing in Lake Ranu Pani. Changes in land characteristics and the intensity of rainfall which is quite high as well as changes in land use are also factors that play a role in the emergence of erosion. Knowing the amount of erosion that occurs in an area is important, because in addition to knowing the amount of eroded soil, it can also be used as a way to find a solution to the problem. This study used the USLE method and the small plot method to calculate the erosion that occurred in hectare cabbage and potato farms. Small plots used measuring 4x2 meters are located on a steep topography (25-40%). This method is used to validate the USLE calculation with the same soil type and slope. Measurements using small plots were carried out for 1 month every rainy event. In the small plot method on a mixed land of cabbage and potatoes, the erosion value was 21.27 tons.ha-1.year-1, while the USLE method was 74.23 tons.ha-1.year-1. Based on the results of these calculations, this agricultural land has a heavy classification on the USLE method and medium on the small plot method. Keywords:  Bromo Tengger Semeru National Park (TNBTS), erosion, Ranu Pani Village, small plot, topography, USLE

Abstract

Plantations of fast growing tree species are imperative in climate change mitigation efforts as of their enormous potential for carbon storage and, this potential largely affected by tree species type. This study estimates biomass and soil organic carbon (SOC) under fast-growing tree species in western Ethiopia. Parameters, height (H) and diameter at breast height (DBH) were measured in permanently plots to evaluate the biomass carbon stock of selected species. Soil samples (0–15 and 15-30 cm) were also collected to determine soil organic carbon (SOC) and bulk density. Above and below-ground biomass (AGB) and (BGB) were estimated using the species-specific allometric equations while SOC was analysed in the laboratory. The results showed that the highest biomass carbon stock was recorded for Eucalyptus globulus (5.7Mg C ha-1) and the lowest was recorded for Eucalyptus grandis (1.2 Mg C ha-1). The highest and lowest mean total soil organic carbon (SOC) was recorded for Eucalyptus saligna (60 Mg C ha-1), and Eucalyptus viminalis (35.4 Mg C ha-1), respectively. This study revealed plantation sites could enhance carbon stock accumulation both in the biomass and soil organic carbon. Hence, considering of incorporating fast growing tree species in plantations is useful in climate change mitigation strategies.

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

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

ABSTRAK Erosi adalah terjadinya perpindahan tanah dari satu tempat ke tempat lainnya yang disebabkan oleh media tertentu seperti air, angin, dan sebagainya. Penggunaan lahan adalah faktor utama perubahan ekosistem yang sangat berpengaruh dibandingkan faktor lain seperti iklim, tanah, dan topografi. Penelitian ini bertujuan untuk melakukan pemetaan tingkat bahaya erosi dan penentuan rekomendasi teknologi konservasi lahan di kawasan UB Forest, Kabupaten Malang. Waktu penelitian dilaksanakan bulan Mei sampai November Tahun 2022. Area penelitian berada di Kawasan UB Forest dengan luas 554 ha tepatnya di Desa Tawangargo, Kabupaten Malang. Metode pengolahan data dilakukan dengan menggunakan Universal Soil Loss Equation (USLE) dan Sistem Informasi Geografis yaitu metode overlay. Tingkat Bahaya Erosi dihitung dengan membandingkan tingkat erosi dari suatu satuan lahan dengan kedalaman tanah efektif. Pengelolaan lahan kawasan UB Forest terdiri dari lahan agroforestri, lahan pemukiman, dan lahan semak belukar tidak terganggu. Berdasarkan hasil klasifikasi tingkat bahaya erosi pada kawasan UB Forest menunjukkan bahwa kelas tingkat bahaya erosi bervariasi dari kelas Sangat Ringan (SR) hingga kelas Sangat Berat (SB). Berdasarkan hasil perhitungan dan klasifikasi, rekomendasi mitigasi atau upaya konservasi tanah yang diberikan memberikan perubahan yang signifikan pada kelas tingkat bahaya erosi setiap satuan lahan. Sehingga, terdapat perubahan signifikan pada nilai erosi potensial dan kelas erosi. Kata kunci: agroforestri, erosi, Kawasan UB Forest ABSTRACT Erosion is the movement of soil from one place to another caused by certain media such as water, wind, and so on. Land use is the main factor of ecosystem change which is very influential compared to other factors such as climate, soil, and topography. This study aims to map the level of erosion hazard and determine recommendations for land conservation technology in the UB Forest area, Malang Regency. The time of research was carried out from May to November 2022. The research area is in the UB Forest area with an area of 554 ha to be precise in Tawangargo Village, Malang Regency. The data processing method is carried out using the Universal Soil Loss Equation (USLE) and the Geographic Information System, namely the overlay method. The Erosion Hazard Level is calculated by comparing the erosion rate of a land unit with the effective soil depth. Land management in the UB Forest area consists of agroforestry land, residential land, and undisturbed shrub land. Based on the classification results of the erosion hazard level in the UB Forest area, it shows that the erosion hazard class varies from Very Light (SR) to Very Severe (SB) classes. Based on the results of calculations and classifications, the mitigation recommendations or soil conservation efforts given to provide a significant change in the class of erosion hazard level for each land unit. Thus, there is a significant change in the potential erosion value and erosion class. Keywords:  agroforestry, erosion, UB Forest Area
