Abstract

Pembangunan fasilitas landfill limbah Bahan Berbahaya dan Beracun (B3), khususnya limbah medis rumah sakit, memerlukan perencanaan geoteknik yang memadai untuk menjamin kestabilan struktur dan perlindungan lingkungan. Pada Tugas Akhir ini dilakukan analisis kondisi geoteknik pada lokasi rencana pembangunan landfill, yang meliputi analisis kestabilan lereng landfill dan tanggul. Analisis ini bertujuan untuk memastikan landfill dan tanggul tetap stabil dalam menerima beban limbah. Pada tahap pembangunan dilakukan galian sedalam 10 meter dengan kemiringan lereng 1:2,5 sehingga lapisan tanah dengan konsistensi medium terangkat seluruhnya. Berdasarkan kondisi tersebut, tanah dasar landfill dinilai tidak berpotensi mengalami pemampatan signifikan sehingga analisis pemampatan tidak dilakukan. Hasil analisis stabilitas menunjukkan bahwa kestabilan internal landfill memenuhi kriteria keamanan sehingga tidak diperlukan perkuatan. Namun, pada analisis kestabilan tanggul dan overall stability landfill diperoleh nilai faktor keamanan yang belum memenuhi persyaratan. Oleh karena itu, direncanakan perkuatan overall stability landfill menggunakan micropile serta perkuatan tanggul menggunakan geotextile. Selain itu, analisis juga dilakukan terhadap kolam pond yang berada di sisi landfill untuk memastikan kestabilannya tetap terjaga pada kondisi landfill terisi limbah. Lapisan dasar sanitary landfill direncanakan menggunakan sistem liner berupa geomembrane kedap air untuk mencegah rembesan lindi ke dalam tanah dan melindungi kualitas air tanah. Sanitary landfill ini juga dilengkapi dengan sistem drainase lindi yang terdiri dari saluran primer dan sekunder yang mengalirkan lindi ke dalam sumur lindi. Pada permukaan landfill, direncanakan saluran drainase pasangan batu untuk mengalirkan air hujan menuju kolam pond. Berdasarkan hasil perencanaan, sanitary landfill limbah B3 ini telah memenuhi aspek teknis dan lingkungan yang dipersyaratkan.

The development of a landfill facility for Hazardous and Toxic Waste (B3), particularly medical waste from hospitals, requires adequate geotechnical planning to ensure structural stability and environmental protection. This Final Project presents a geotechnical analysis of the proposed landfill site, including slope stability analyses of the landfill and its embankments. The analyses aim to ensure that the landfill and embankments remain stable under the applied waste loads. During the construction stage, an excavation with a depth of 10 meters and a slope inclination of 1:2.5 was carried out, resulting in the complete removal of soil layers with medium consistency. Based on these conditions, the landfill subgrade was assessed as having no significant potential for settlement; therefore, settlement analysis was not conducted. The results of the stability analysis indicate that the internal stability of the landfill satisfies the required safety criteria, and thus no reinforcement is necessary. However, the stability analysis of the embankment and the overall stability of the landfill show safety factors that do not meet the required standards. Consequently, reinforcement of the overall landfill stability using micropiles and embankment reinforcement using geotextiles were implemented. In addition, an analysis was conducted to ensure the stability of the adjacent pond, which is located next to the landfill, under landfill-loaded conditions. The base layer of the sanitary landfill was designed using a geomembrane liner system to prevent leachate seepage into the underlying soil and to protect groundwater quality. Furthermore, the sanitary landfill is equipped with a leachate drainage system consisting of primary and secondary channels that convey leachate to a leachate collection well. Surface drainage channels constructed with stone masonry are also provided to collect and direct rainfall runoff into the pond. Based on the planning results, the B3 sanitary landfill fulfills the required technical and environmental criteria.
