Abstract

Tempat Pembuangan Akhir (TPA) Supit Urang Malang, yang berlokasi di Kelurahan Mulyorejo, Kecamatan Sukun, Malang, berperan sebagai pusat penanganan sampah di dalam kota. Sampah yang dikelola di TPA Supit Urang berasal dari berbagai wilayah layanan, mencakup sampah dari pasar, rumah tangga, taman, bisnis, industri kecil, dan sejumlah sumber lainnya. Seiring dengan berjalannya waktu, risiko pencemaran air tanah di sekitar TPA Supit Urang terus meningkat sejalan dengan operasional TPA. Pencemaran air tanah di sekitar lokasi tersebut tidak hanya disebabkan oleh limbah domestik, tetapi juga oleh faktor-faktor lain. Penelitian ini memiliki tujuan untuk mengidentifikasi perilaku dan persepsi masyarakat yang tinggal dalam radius kurang dari 2 km dari Tempat Pembuangan Akhir (TPA), terkait dengan pencemaran air tanah oleh TPA Supit Urang. Metode penelitian ini berfokus pada pengumpulan data primer melalui survei dan wawancara dengan melibatkan 100 responden, serta menggunakan data sekunder. Hasil survei menunjukkan bahwa sebagian besar responden mengalami masalah dengan air sumur mereka yang sering menguning pada musim tertentu. Dari segi persepsi masyarakat, sekitar 32% menganggap bahwa kondisi air tanah di sekitar TPA Supit Urang saat ini tercemar oleh besi atau mangan, 16% menyatakan kondisinya baik, sementara sisanya tidak mengetahui karena telah lama menggunakan air sumur tanpa ada keluhan kesehatan. Persepsi ini didasarkan pada kondisi air sumur warga, termasuk kejernihan dan bau air. Selain manajemen sampah, kondisi lingkungan sungai di sekitar TPA Supit Urang juga dipengaruhi oleh sistem sanitary landfill yang tidak terpelihara dan sanitasi yang kurang memadai. Untuk menjaga kualitas air tanah di TPA Supit Urang, masyarakat dan pihak terkait telah aktif melakukan pemeliharaan terhadap sistem sanitary landfill secara berkelanjutan. Kajian awal ini diharapkan dapat memberikan informasi awal yang bermanfaat dalam upaya pengelolaan kualitas air tanah sebagai sumber air baku yang melibatkan partisipasi masyarakat secara berkesinambungan.Kata Kunci: air tanah, pencemaran, sumur, kesadaran,sampah

Abstract

Domestic waste is the largest contributor to the amount according to waste criteria. So according to Law Number 18 of 2008 concerning Waste Management, household waste has special specifications in its handling patterns, the use of cleaning materials generally causes households to produce toxic and dangerous waste which is designated as specific waste. Specific waste itself is regulated in Government Regulation Number 27 of 2020 concerning Specific Waste Management. The urgency of specific household waste management is that the correlation between the two policies has not been studied. The analysis of the approaches to these two policies aims to implement the most appropriate pattern for handling domestic hazardous and toxic waste. Based on calculation results, the generation of hazardous and toxic household waste in the Regency/City of West Java Province is estimated at 416.47 tons/day and there is no special handling yet. The integrated handling pattern is still not operational because these two policies do not yet have a relationship study, because the special characteristics of these two types of waste are in contrast to their decomposition properties.

Abstract

Forearm fracture defined as fracture that occurs in the forearm, where the radius and ulna bones are both broken. Forearm fracture is the most common type of fracture that occurs in children and adults. Traffic accident is one of the cause of this fracture. The initial approach in non-complicated forearm fracture is closed reduction with cast immobilization (conservative therapy). The aim of this study is to analyze the success rate of closed reduction of the forearm fracture at Bethesda Hospital of Yogyakarta. The study also examines the relationship between the type of fracture and the related success rate of closed reduction on forearm fracture as well as the distribution of forearm fracture at Bethesda Hospital, Yogyakarta. This is a descriptive study with cross-sectional design. Radiographs and medical records of patients with forearm fracture at Bethesda Hospital, Yogyakarta were analyzed retrospectively in the period of 2007-2013. The measured variables are the change in the degree of angulation, apposition changes, gap occurrences, and the presence of overlap between radiological examinations before and after closed reduction. Medical records are also analyzed after reduction is done. Data is statistically analyzed using Chi-Square method. The result shows that closed reduction of forearm fracture performed by emergency team of Bethesda Hospital Yogyakarta during the period of 2007-2013 was quite successful and there is a significant relationship between the type of fracture with the success rate of closed reduction of forearm fracture (p=0.003). Thus, closed reduction is a mainstay initial approach in the patients with forearm fracture. If it is not successful, then surgery can be performed.

Abstract

The increasing demand for environmentally friendly construction materials has encouraged the use of industrial and organic waste, such as fly ash and coconut fiber, as alternative additives in paving block production. This study aims to evaluate the effects of using fly ash as a partial cement replacement and coconut fiber as an additive on the mechanical strength and environmental aspects of paving blocks. The research method is experimental, based on SNI 03-0691-1996 and ASTM C109/C109M-21 standards. The mix variations consisted of 0%, 10%, 15%, and 20% fly ash, with an addition of 2% coconut fiber, using two curing methods: room temperature and water immersion. The compressive strength test results at 28 days showed that room temperature curing produced values of 11.07 MPa, 11.58 MPa, 12.85 MPa, and 12.06 MPa, respectively. Meanwhile, water immersion curing yielded 14.40 MPa, 14.89 MPa, 16.13 MPa, and 15.69 MPa. The highest flexural strength, 4.25 MPa, was achieved with a mixture of 10% fly ash and 2% coconut fiber cured by water immersion. The use of fly ash and coconut fiber not only enhances the mechanical strength of paving blocks but also contributes to reducing industrial and agricultural waste. This combination has proven effective in improving material performance while supporting sustainable development as an eco-friendly solution
