Abstract

Oldeman agroclimate zone is a classification system used to group areas based on rainfall distribution patterns and soil moisture potential available throughout the year. This system provides a clearer picture of which areas are suitable for certain crops based on their water needs, as well as optimizing the use of existing climate resources through cropping patterns arrangements. This study aims to identify and analyze Oldeman agroclimate zones to determine the right planting season and develop efficient food crop cropping patterns on Kisar Island. This study combines two approaches, namely descriptive and quantitative with the following analysis stages: generating rainfall data, calculating average regional rainfall, determining agroclimate zones, determining planting seasons, and arranging cropping patterns. The results of the study indicate that Kisar Island is included in Agroclimate Zone E3 with a planting season length of 7 months, starting in December and ending in June. Intercropping or mixed cropping patterns are options in corn and legume cultivation. To avoid water shortages during the reproductive phase of the plant, dryland rice planting should be carried out in the period from March to June.

Abstract

Penelitian ini bertujuan mengevaluasi faktor pembatas kesesuaian lahan untuk pengembangan agroekowisata, menilai kesesuaian lahan bagi komoditas tanaman pilihan, serta merumuskan arahan pengembangan agroekowisata yang berkelanjutan di hulu DAS Batu Gajah, Kota Ambon. Kelas kesesuaian lahan ditentukan menggunakan metode Analytical Hierarchy Process (AHP), sedangkan evaluasi kesesuaian komoditas (nenas, salak, durian, dan duku) didasarkan pada persyaratan tumbuh masing-masing tanaman. Hasil penelitian menunjukkan lahan terbagi dalam dua kelas, yaitu Cukup Sesuai (S2) seluas 113,43 ha (33,9%) dengan pembatas ketersediaan objek wisata, dan Hampir Sesuai (S3) seluas 220,90 ha (66,07%) dengan pembatas tambahan pada aspek pengelolaan. Dari empat komoditas yang dianalisis, nenas terpilih sebagai unggulan dengan kelas S3 seluas 172,84 ha (51,7%) dan faktor pembatas curah hujan dan kemiringan lereng, sementara 161,49 ha (48,3%) tergolong Tidak Sesuai (N) akibat kemiringan lahan curam. Arahan pengelolaan menekankan pengembangan agroekowisata berbasis komoditas nenas. Strategi yang direkomendasikan meliputi pembangunan peningkatn sarana-prasarana wisata, optimasi lahan sesuai kondisi fisik, dan pelibatan masyarakat.

Abstract

This study aims to identify and describe soil morphological traits in the granite toposequence and analyze these traits to assess the similarity index between soil profiles. This study used a survey method involving transect observations and complete profile observations. Variable soil observations were made in a downward direction, following each change in slope segment on the granite toposequence. The results showed that Cambisol (Dystrudepts) soils developed with physical and chemical properties on three profiles for soil color ranging from yellowish brown to brownish yellow and yellowish red to red. The soil texture ranges from loamy sand to dusty clay, and the soil structure is rounded cubical. The soil has an acidic to slightly acidic pH and a slightly sticky consistency when moist and very low to low C-organic content. The similarity index assessed in the three profiles includes parameters such as dust/clay ratio, pH H₂O, and C-organic, which are very similar due to the similarity of the constituent rock formations.
