Signs of soil that has undergone advanced development include clearer horizons, higher fine fraction and lower coarse fraction, brighter soil color, higher levels of free Al and Fe. Soil aggregation is increasing, to a certain extent organic matter and nutrient levels are increasing as well as CaCO levels, and soluble salts. Soil development is characterized by the occurrence of horizon differentiation as a representative of the process of change in the earth's skin both physically, chemically and biologically by reactions in the soil profile there is an addition of organic and mineral materials in the form of solid, liquid or gaseous materials, the disappearance of materials above the soil, the transfer of materials from one part to another in the soil body, the transfer of the form of mineral compounds and organic matter in the soil body This research was carried out in the village of Bobaneigo Madihutu, South Jailolo District, West Halmahera Regency from June to July 2023. The method used in data collection is a free survey method, which is an observation made directly in the field by determining the research location based on land use maps, and administrative maps. The variables observed were C-Organic, N-Total, C/N Ratio, CEC, KB which are soil chemical properties. The results showed that the study of the level of soil development in several types of land use has not experienced weathering or advanced development due to the low content of nutrients.

Kompleksitas proses pedogenesis pada pulau vulkanik kecil yang berpengaruh terhadap tingkat perkembangan tanah, khususnya ordo Entisol dan Inceptisol di Kelurahan Moti Kota, Kota Ternate. Kondisi iklim tropis basah, bahan induk piroklastik Kuarter–Holosen, serta variability topografi memunculkan perbedaan morfologi dan sifat fisik-kimia tanah yang signifikan. Tujuan penelitian adalah mengidentifikasi dan membandingkan variasi tingkat perkembangan profil tanah berdasarkan indikator pedogenik termasuk nisbah debu/liat, KTK/liat, rasio C/N, dan rasio Fe-oksalat/Fe-dithionit serta mendeskripsikan karakteristik morfologi, fisik, dan kimia tanah pada dua profil representatif, yakni Entisol (profil II) dan Inceptisol (profil I). Metode yang digunakan meliputi survei toposekuens dengan penggalian profil pada setiap posisi elevasi, deskripsi morfologi lapangan sesuai prosedur USDA, analisis tekstur (metode pipet), pH H₂O, kapasitas tukar kation (NH₄OAc pH 7,0), Saturasi Basa, karbon organik (Walkley–Black), total N (Kjeldahl), serta ekstraksi besi oksalat dan dithionit. Data kuantitatif dianalisis untuk menghitung nisbah indikator pedogenesis dan diklasifikasikan menurut Soil Taxonomy USDA. Hasil penelitian menunjukkan bahwa profil I (Inceptisol) membentuk horizon cambic dengan struktur gumpal menyudut, peningkatan fraksi liat dari 20 % hingga 35 %, nilai KTK 19,95–23,25 cmol(+)/kg, dan decreasing basa saturation dari 60 % ke 33 %. Indikator nisbah debu/liat menurun dari 1,25 pada horizon Ap ke 0,15 pada horizon Bb/C, sedangkan rasio Feₒ/Fe_d berfluktuasi menandakan proses transformasi oksida besi lanjutan. Sebaliknya, profil II (Entisol) hanya memiliki horizon A dengan tekstur lempung berpasir, KTK 20,95 cmol(+)/kg, saturasi basa 62 %, nisbah debu/liat 0,85, dan rasio Feₒ/Fe_d 1,10, menggambarkan tanah muda dengan sedikit perkembangan horizon. Kesimpulan penelitian menyatakan bahwa interaksi bahan induk vulkanik, iklim lembap tropis, organisme, topografi, dan waktu menghasilkan gradiens perkembangan tanah dari Entisol ke Inceptisol di Kelurahan Moti Kota. Pemahaman mendalam terhadap variasi ini penting untuk perencanaan penggunaan lahan berkelanjutan, di mana Inceptisol cocok untuk hortikultura intensif dan Entisol memerlukan tutupan vegetatif untuk mencegah erosi.

This study evaluates land capability in Tafamutu Village, Moti District, Ternate City, as a basis for sustainable land-use planning. Employing the Land Capability Classification (LCC) framework and the Land Classification and Land Use Planning (LCLP) software, the analysis identifies five land capability classes (V–VIII) across sixteen land mapping units. Subclass V‑P1, occupying 7.6 ha (1.1%), is constrained by slow permeability (< 25 mm/h). In contrast, subclass V‑b3, covering 100.4 ha (14.9%), is characterized by high coarse fragment content (> 90%), resulting in splash erosion rates of up to 22.3% under intense rainfall. Class VI‑E, comprising 135.3 ha (20.1%), is defined by moderate slopes (30%–45%) and elevated surface runoff potential—up to 75% higher compared to gentle slopes (< 15%). Class VII‑e5 encompasses 143.9 ha (21.4%) and is marked by severe erosion, with rates reaching 1,738.2 t ha⁻¹ yr⁻¹. Class VIII‑G, the most significant area at 261.2 ha (38.9%), includes very steep slopes (> 65%) and is designated strictly for conservation purposes. The dominant soil textures are clay loam and sandy loam, with an average adequate depth of 80 cm and a pH range of 5.0–6.5. These edaphic conditions support the cultivation of cloves and nutmeg, contingent upon implementing appropriate soil conservation techniques such as terracing and organic mulching. Based on the land capability assessment, recommended land uses include grazing on Class V lands (108 ha; 16.5%), limited plantation development on Class VI (135.3 ha; 20.1%), production forestry on Class VII (143.9 ha; 21.4%), and strict protection as forest reserves on Class VIII (261.2 ha; 38.9%). These zoning guidelines are instrumental in promoting climate-resilient land management and the sustainable utilization of natural resources within coastal volcanic landscapes.
