Abstract

Tanah merupakan material utama dalam dunia konstruksi, karena semua bangunan akan bertumpu pada tanah. Ada beberapa jenis tanah yang bermasalah baik dari segi daya dukung tanah, salah satunya tanah lempung. Seperti tanah di daerah Desa Separi, Tenggarong Sebrang, Kutai Kartanegara yang tergolong tanah lempung sehingga penelitian ini bertujuan untuk menjadi alternatif stabilisasi dan perkuatan tanah lempung dengan mencampurkan sirtu dan kapur. Tanah yang digunakan pada penelitian ini berdasarkan klasifikasi AASHTO termasuk dalam kelompok A-7-5. Sirtu yang digunakan sebagai bahan tambah pada penelitian ini diambil dari desa Desa Apung, Kecamatan Tanjung Selor, Kabupaten Bulungan, dan Kapur yang digunakan adalah kapur tohor. Variasi sirtu pada pengujian ini 15%, 20%, dan 25%, sedangkan variasi kapur 2%, 4%, dan 6%. Pada pengujian ini dilakukan uji kuat tekan bebas dan CBR untuk mengetahui nilai daya dukung tanah asli maupun tanah campuran. Hasil penelitian yang dilakukan dengan penambahan sirtu dan kapur dapat memperbaiki daya dukung tanah, dengan pengujian kuat tekan bebas campuran 25% sirtu dan 4% kapur didapat nilai optimum qu 3,516 kg/cm2. CBR tanah campuran 25% sirtu dan 6% kapur dengan nilai 11,35% memenuhi syarat CBR tanah sebagai dasar perkerasan jalan minimal 6%.

Abstract

This research aims to elucidate the underlying values and representations of nature and humanity. The study employs a qualitative approach, utilizing the hermeneutic method for interpretation and analysis. Drawing upon ecocritical perspectives, the research explores the intricate relationship between literature and the environment, highlighting the significance of literature in advocating for environmental conservation. The poem unfolds through the first-person perspective of 'Aku,' depicting their deep connection to the teak forest, which symbolizes both the physical landscape and the emotional journey of the narrator. Through vivid imagery and evocative language, the poem portrays themes of love, loss, and environmental degradation, emphasizing the profound interconnectedness between humanity and the natural world. Additionally, the portrayal of childhood innocence and imagination underscores the transformative power of curiosity, showcasing the inherent bravery and resilience of the human spirit. Moreover, the analysis delves into the cultural landscape depicted in the poem, unveiling the community's profound reverence for the environment encapsulated in their rich tapestry of myths and mystical narratives. These myths serve as potent instruments, instilling in individuals a deep sense of responsibility towards environmental stewardship. The poem masterfully weaves together the threads of human experience and environmental consciousness, inviting readers to contemplate the symbiotic relationship between humanity and nature. Through rich sensory imagery and poignant reflection, the poem celebrates the inherent beauty and richness of the natural world while urging reflection on the profound impact of human actions on the delicate balance of the ecosystem.
