Abstract

Sidoarjo mud (well known as LUSI) have been occurred since 2006 in Sidoarjo, East Java, Indonesia and gives many impacts to many aspects, as well as environment and water quality condition. One of the major concerns is water quality problem, especially in this current situation in 2022 since clean water still needed by local people and groundwater is the main water source for many local people in this area. Our previous study has carried out to assess the ecological and geochemical conditions of groundwater in the area around Sidoarjo mud in 2022. In this study, by using Pollutant Index (PI) calculation, the water quality classification will be determined from several samples and parameters in various places, including Tanggulangin, and Porong, Sidoarjo, East Java. From the calculation result, based on Pollution Index (PI) value, water in Tanggulangin is categorized as good water (clean water), while water in Porong is categorized as good water (clean) as well for sample B3, and the rest is categorized as lightly polluted water with sample B5 as the most contaminated. Groundwater in the area near to Sidoarjo mud is contaminated by NO2-, Mn, and Hg.

Abstract

ABSTRAK  Emisi karbon merupakan isu yang sangat berdampak pada pemanasan global, peningkatan bencana hidrometeorologi dan penurunan sumberdaya alam. Salah satu cara mengurangi emisi karbon adalah mencegah perubahan tutupan lahan terutama hutan pada daerah tropis seperti Kawasan DAS Blega. Penelitian ini bertujuan untuk melihat perubahan tutupan lahan dan dan pengaruhnya terhadap stok karbon permukaandi DAS Blega tahun 1990-2020. Penelitian dilakukan di area DAS Blega melalui 6 tahapan, yaitu koreksi geometric, komposit band, training sample pada Area of Interest (AoI), uji Training sample, klasifikasi tutupan lahan dan menghitung stok karbon. Hasil analisis menunjukkan rata - rata tutupan lahan pada tahun 1990, 2000, 2010 dan 2020 terluas berturut-turut adalah pertanian lahan kering (69%), hutan tanaman (11.2%), sawah (8.77%), hutan tanaman (4.59%), tambak (2.65%), pertanian lahan kering campur (1.56%), hutan mangrove sekunder (0.87%), pemukiman (0.70%), belukar (0.63%) dan sisanya tanah terbuka. Perubahan tutupan lahan 1990-2000 dari belukar rawa menjadi pertanian lahan kering (8,819.81 ha), sawah (2,629.13 ha) dan pemukiman (152.57 ha). Periode 2000-2010 terjadi perubahan tutupan lahan pada pertanian Lahan Kering Campur-Pemukiman sebesar 654.14 ha. Periode 2010-2020 terjadi konversi lahan tertinggi pada sawah - tambak dengan luas 4,571.08, belukar - sawah, dan hutan mangrove sekunder - tambak masing - masing luas 343.12 dan 316.13 ha serta sebagian kecil penutup lahan lainnya. Selanjutnya, periode 2010-2020 tutupan lahan sawah mengalami penurunan sebesar 4,302.7 ha. Perubahan tutupan lahan tersebut berpengaruh pada perubahan stok karbon di DAS Blega, yakni selama periode tahun 1990-2020 mengalami penurunan sebesar 25.98%. Tahun 1990-2000 mengalami penurunan 19.41%, tahun 2000-2010 dan 2010-2020 mengalami penurunan masing-masing sebesar 1.55% dan 5.02%. Kata kunci: emisi karbon, karbon permukaan, madura ABSTRACT Carbon emissions are a strategic issue because of the impact on global warming, increased hydrometeorological disasters, and decreased natural resources. One way to reduce carbon emissions is to prevent land cover change, especially forests for other uses in tropical areas such as forests in the Blega watershed area. This study aims to look at land cover change and its effect on surface carbon stock in the Blega watershed from 1990-2020. This research was conducted in the Blega watershed area through 6 stages, namely: 1) Geometric correction, 2) Band composite, 3) Training sample on Area of Interest (AoI), 4) Training sample test, 5) Land cover classification and 6) Carbon stock calculation. The results of image analysis of the Blega watershed area show that the average land cover in 1990, 2000, 2010, and 2020 are dry land agriculture (69%), plantation forest (11.2%), rice fields (8.77%), plantation forest (4.59%), ponds (2.65%), mixed dry land agriculture (1.56%), secondary mangrove forest (0.87%), settlements (0.70%), shrubs (0.63%) and the remaining open land. The land cover changed 1990-2000 from swamp scrub to dry land agriculture (8,819.81 ha), paddy fields (2,629.13 ha), and settlements (152.57 ha). The period 2000-2010 saw land cover change in Mixed Dryland Agriculture-Settlement of 654.14 ha. The 2010-2020 period saw the highest land conversion in paddy fields - ponds with an area of 4,571.08, scrub - paddy fields, and secondary mangrove forest - ponds with an area of 343.12 and 316.13 ha respectively, and a small portion of other land covers. Furthermore, in the 2010-2020 period, rice field land cover decreased by 4,302.7 ha. The change in land cover affects the change in carbon stock in the Blega watershed, which during the 1990-2020 period decreased by 25.98%.1990-2000 experienced a decrease of 19.41%, 2000-2010 and 2010-2020 experienced a decrease of 1.55% and 5.02% respectively. Keywords: carbon emissions, surface c stock, madura

Abstract

ABSTRACT The protection and monitoring of fauna species are essential for maintaining biodiversity and ensuring the sustainability of ecosystems. Traditional methods of fauna conservation and habitat monitoring rely heavily on manual observation and data collection, which can be time-consuming, and labor-intensive. In recent years, the application of machine learning techniques, such as object detection, has shown great potential in automating the identification of fauna species. In this study, we propose an approach to advancing fauna conservation through the utilization of machine learning-based spectrogram recognition. Specifically, we employ an object detection algorithm, YOLOv5, to detect and classify fauna species from spectrogram images obtained from acoustic recordings. The spectrograms provide a visual representation of audio signals, capturing distinct patterns and characteristics unique to different fauna species. Through extensive experimentation and evaluation, our approach achieved promising results, demonstrating a precision of 0.95, recall of 0.98, F1 score of 0.91, and mean Average Precision (mAP) of 0.934. These performance metrics indicate a high level of accuracy and reliability in fauna species detection. By automating the identification process, our approach provides a scalable solution for monitoring fauna populations over large geographical areas and enables the collection of comprehensive data, facilitating better decision-making and targeted conservation strategies. Keywords: acoustic recording, fauna conservation, machine learning, spectrogram, YOLOv5

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
