Abstract

Lembaga kesehatan seperti rumah sakit wajib mengelola limbah medis padat dengan baik karena limbah tersebut berpotensi mengandung B3. Penanganan yang tepat sangat penting mengingat bahan-bahan ini sering mengandung zat berbahaya yang memerlukan prosedur penanganan dan pembuangan khusus. Ketidaktepatan dalam penanganan residu medis ini dapat mengakibatkan kerusakan lingkungan jangka panjang serta menimbulkan bahaya kesehatan yang serius bagi masyarakat yang terpapar. Rumah Sakit "X"menghadapi tantangan dalam pengelolaan limbah medis padat. Permasalahan utama berkaitan dengan tenaga medis yang sering mencampurkan limbah medis padat. Masalah tambahan muncul dari petugas kebersihan yang tidak mematuhi protokol penggunaan Alat Pelindung Diri (APD) secara lengkap, sehingga meningkatkan kemungkinan terpapar cairan biologis pasien. Penelitian ini bertujuan untuk menyebarkan sumber daya medis padat di Rumah Sakit "X" serta melakukan perbandingan dengan regulasi yang tercantum dalam Permen LHK Nomor 56 Tahun 2015. Penelitian ini menggunakan metode deskriptif kualitatif dan analisis kuantitatif. Teknik pengumpulan data dilakukan melalui wawancara, observasi langsung, dan dokumentasi. Evaluasi kepatuhan terhadap regulasi yang berlaku dilakukan melalui analisis data kuantitatif yang diperoleh dari instrumen checklist dengan penilaian menggunakan metode skala Likert untuk mengukur derajat kesesuaian. Berdasarkan temuan penelitian, persentase kepatuhan rumah sakit dalam penerapan pemeliharaan limbah medis mencapai angka sebesar 81,97% yang termasuk dalam kategori baik sekali. Rekomendasi yang diberikan adalah pihak Sanitasi Rumah Sakit "X" sebaiknya melakukan edukasi melalui sosialisasi dan pelatihan rutin kepada seluruh staf rumah sakit tentang pentingnya pemilahan limbah medis yang tepat. Selain itu, perlu juga mempertimbangkan untuk melakukan pemeriksaan mendadak untuk memastikan bahwa prosedur telah diikuti oleh seluruh staf rumah sakit.

Abstract

Indonesia's largest bauxite reserves are in the province of West Kalimantan, which is 703 million tons Bauxite is formed from rocks with a high relative aluminum (Al) content, low iron (Fe) content, and small amount of quartz. The mineralogy and characteristics of lateritic bauxite deposits are closely related to several factors, one of which is the texture and composition of the bedrock such as color, mineral composition, and shape of the ore. This study discusses the genetic type of bauxite deposits based on mineralogy and geochemistry using mineragraphic, XRD, and XRF methods. The primary data from bauxite ore samples were collected from the stockpile of PT. Dinamika Sejahtera located in Toba area. The quantitative result of the geochemical analysis indicates a higher amount of alumina observed using the XRF method. Granodiorite bauxite, which is bauxite coming from granodiorite bedrock, generally has abundant geochemical elements, especially SiO2 and Al2O3. The lateritic bauxite type in the Toba area is a product of granodiorite weathering from the Sepauk Tonalite formation is embedded within a clay matrix which exhibits a brownish to red color with coarse to boulder-size of concretion texture without relict. Some important elements in bauxite laterite deposits are Al, Fe, Si (Silicon), and Ti (Titanium). The comparison between Al and Si values is a benchmark for the economics of bauxite mines. Gibbsite is the major mineral in the bauxite ore, while hematite, goethite, kaolinite, and quartz are the accessory minerals. The deposit is recognized as Low-Fe bauxite due to comparing Al2O3, Fe2O3, and Si2O3 concentrations. The weathering process has altered the primary texture, remaining resistant and secondary minerals. The petrographic analysis shows the replacement of Gibbsite as bauxite ore which presents as kaolinite replacement and fills the mineral cracks. The result of this study is expected to be useful in determining the exploration method for the bauxite deposits.

Abstract

Peat soil is composed mainly of organic matter, which directly impacts on the water quality in peatlands. The water in peatlands, also known as peat water, is high in organic matter, low in pH, and brown in colour. To make it suitable for daily use, such as bathing and toilet flushing, peat water must be treated. This research aims to treat peat water using Fe3O4 to reduce organic matter and a filtration process with shell sand to overcome pH and turbidity issues. The research results showed that the maximum dose of Fe3O4 to reduce turbidity is 0.0002 g/mL. Higher doses of Fe3O4 were found to increase turbidity due to the dissolution of Fe in peat water. The filtration process of peat water treated with Fe3O4 in improved pH levels that meet the quality standards. However, it also increased the turbidity due to the dissolution of fine shell sand particles in the peat water. To obtain the best conditions for effective adsorption of particles that cause turbidity, pH conditioning must be carried out before adding Fe3O4. It is also necessary to standardize the particle size of shell sand to minimize the dissolution of fine particles that can increase turbidity.

Abstract

The community's need for clean water is a complex matter in meeting needs such as washing, cooking, bathing and other needs, so the quality and quantity need to be maintained. The Jalan Parit Wagattak area still uses drilled well water to fulfill daily needs because there is no distribution route from PDAM. The quality of iron (Fe) parameters at the research location does not meet the quality standards, namely still 1.52 mg/L. This research aims to make the drilled well water used suitable by processing it using a coagulation-filtration process. The optimum dose of chlorine obtained from the Jar Test results was 5 mg/L with a maximum stirring time of 30 minutes. The zeolite filter media used has a height of 20 cm with a PVC pipe container diameter of 3 inches. The results of the allowance for turbidity parameters from 221 NTU to 12.67 NTU (94.26%), color from 32.9 Pt-Co to <1.45 Pt-Co (95.59%), iron (Fe) 1.52 mg/L decreased to 0.04 mg/L (97.36%), Escherichia coli 16 MPN/ml to 0.89 MPN/ml (94.43%), pH increased from 6.4 to 7.2, and the remaining free chlorine (Cl2) from 0.03 mg/L to 0.04 mg/L. Based on the research carried out, it is necessary to determine the contact time between water and zeolite to eliminate turbidity and Escherichia coli happens to the maximum.
