This investigation examines the effect of clamshell ash (CSA) and lime additives on the physico-mechanical characteristics of kaolinite clay soil stabilized at the optimum silica fume content. Laboratory tests were performed to assess plasticity, shrink-swell characteristics, compaction characteristics, unconfined compressive strength (UCS), shear strength characteristics, mineralogical and morphological microstructure characteristics of stabilized soil specimens. The kaolinite clay soil was stabilized at its optimum silica fume content (6%) to produce the highest strength and was altered with three non-identical proportions of clamshell ash and lime (3%-9%). Cylindrical soil specimens, 76 mm in height and 38 mm in diameter, were moulded and treated for curing periods of 1, 7, 14, and 30 days to examine the strength of the altered soil. The findings revealed that, adding clamshell ash and lime significantly alters the plasticity, shrink-swell, maximum dry unit weights, and optimum moisture contents of the silica fume-stabilized soil. In terms of strength, the beneficial effects of CSA and lime additives were found to be more significant with more extended curing periods. Incremental increases in curing periods resulted in further enhancements in UCS, cohesion, and internal friction angle, indicating continued strength development over time. Microstructural analysis using field emission scanning electron microscopy and X-ray diffraction provided insights into the interparticle bonding mechanisms and microstructural changes induced by the addition of CSA and lime. The emergence of cementitious phases and pozzolanic responses between soil particles and stabilizers contributed to the densification and strengthening of the stabilized soil matrix. The findings of this study provide valuable insights into the potential of clamshell ash and lime additives to enhance the engineering properties of kaolinite clay soil stabilized with silica fume. These results have implications for sustainable soil stabilization practices, offering a promising approach to improve the performance of soils for various engineering applications, including construction and geotechnical projects.

“…Berdasarkan analisis tanah di laboratorium pada (Tabel 2) menunjukkan nilai KTK pada wilayah penelitian memiliki kategori yang bervariasi diantaranya pada UL 1, 4, 6-8, 21 dan 27 memiliki kategori rendah dengan kelas S2, pada UL 31 yang memiliki kategori sedang dengan kelas S1 dan pada UL 2, 3, 5, 9-20, 22-30, 32-36 memiliki kategori sangat rendah dengan kelas S3. (Emamgholizadeh et al, 2022) mengemukakan bahwa salah satu sifat pengontrol fungsi dasar tanah yang berhubungan dengan pH, unsur hara, kontaminan, dan retensi air, oleh karena itu parameter ini merupakan salah satu penentu penting dalam pengelolaan kesuburan tanah. Sebagai contoh, tanah yang telah mengalami pelapukan ekstensif memiliki KTK yang rendah dan kesuburan yang rendah karena proses pelapukan dengan tingkat keasaman tanah yang tinggi dan kandungan unsur hara yang rendah (Lago et al, 2021).…”

Pertambahan penduduk sejatinya harus juga dibarengi dengan pertambahan jumlah produksi untuk menjaga agar kebutuhan pangan masyarakat tetap terjaga. Penelitian ini dilaksanakan dengan maksud untuk mengevaluasi kesesuaian lahan serta menentukan alternatif perencanaan penggunaan lahan untuk pengembangan tanaman jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur. Penelitian ini menggunakan metode survei bebas didasarkan pada unit lahan. Prosedur pelaksanaan survei tanah dilaksanakan dalam beberapa tahap meliputi tahap persiapan, tahap operasi lapangan dan tahap analisis sampel di laboratorium. Perencanaan penggunaan lahan dilakukan berdasarkan evaluasi kemampuan lahan dan besarnya bahaya erosi. Hasil penelitian menunjukkan bahwa pengembangan tanaman pangan di Kecamatan Poleang Timur Kabupaten Bombana sesuai untuk dikembangkan khususnya jagung seluas 5271,29 ha (78,04%), ubi kayu seluas 4872,34 ha (72,14%) dan kacang tanah seluas 5020,77 ha (74,33%). Alternatif arahan pengelolaan lahan untuk pengembangan tanaman pangan khususnya jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur Kabupaten Bombana dilakukan pada tingkat sedang berupa pemupukan untuk faktor penghambat ketersediaan hara, penambahan bahan organik dan pengapuran untuk perbaikan faktor penghambat retensi hara, bahaya erosi diatasi dengan usaha konservasi tanah seperti penanaman sesuai kontur, pembuatan teras dan penanaman tanaman penutup tanah, pembuatan saluran irigasi/pengairan untuk penghambat ketersediaan air. Diharapkan dengan adanya penelitian ini mampu memberikan sumbangsih pemikiran dan sebagai bahan pertimbangan untuk pemerintah daerah setempat dalam hal penyusunan kebijakan serta untuk masyarakat dalam usaha pengembangan tanaman pangan.

“…Emamgholizadeh (2023) predicted soil cation exchange capacity using enhanced machine learning approaches in the southern region of the Caspian Sea. The study found that coupled models (ANFIS-DE and ANFIS-PSO) were more efficient than the ordinary ANFIS model [ 36 ]. Hadadi (2022) applied classic ANFIS to estimate the daily dew point temperature and found that hybrid models (i.e., ANFIS-BCO and ANFIS-DFA) demonstrated better performance compared to classic ANFIS [ 37 ].…”
