Abstract

The evaluation of agricultural commodity zoning is implemented on tidal swamp area in Batola District, South Kalimantan Province . In fact, the quality of land varies from one place to the others due to the presence of limiting factors in it. Therefore a study of land suitability is essentially needed before utilizing land for cultivation. The method used in the study refers to FAO procedure and Soil Research Institute as well. A brief explanation of land resources evaluation, land suitability and commodities zoning for food crop,horticulture, and plantation crop is presented in the methodology. Then, the results of land characterization and suitability classification in Batola District are discussed, so that,more derstanding in respect to land properties and quality is derived. There are threegroups of soils is found the study area, namely peat soils, marine soils and pluviatile soils. By nature those soils have several limiting factors, i.e. drainage (flooding), acidity,sulphate potential, salinity, and low fertility. The highest grade of suitable land in Batola is only S2 (moderately suitable), and the largest area is classified as S3 (marginally suitable) for all analyzed cultivation. Since, the results of land suitability were derived then the commodities zoning were conducted. Water managing, liming, and fertilizing are definitely needed for land development and land reclamation.Key words: land evaluation, commodities zoning, GIS, agriculture

Abstract

Sagu sawit adalah salah satu Genus Metroxylon dari keluarga Palmae , yang mengakumulasi sejumlah besar pati di batangnya. Sebagai sumberdaya makanan bertepung, sagu bisa menjadi peran penting sehubungan dengan kemungkinan kekurangan pangan di dunia di masa depan. Sagu sawit adalah tanaman tropis yang tidak hanya tumbuh di lahan kering, tetapi juga tumbuh dengan adaptasi yang tinggi terhadap lahan basah seperti rawa air tawar, rawa gambut ataubrakish. Asal-usul sagu diyakini membentang dari Maluku dan Papua dari Indonesia ke New Guinea. Namun, perhatian untuk mengeksplorasi penyebaran dan potensi sagu belum dilakukansecara memadai di Papua. Tujuan dari penelitian ini adalah untuk mengembangkan metode statistik spasial untuk pemetaan dan memperkirakan saham sagu di Inanwatan District, Kabupaten SorongSelatan, Papua Barat. Kerangka sampling area berupa metode segmen persegi yang diterapkan untuk memperkirakan stok sagu, yang melibatkan beberapa tahapan, yaitu, (1) Stratifikasi daerahpenelitian dengan menggunakan resolusi tinggi dari data satelit, (2) Desain survei kerangka sampel, (3) Survei lapangan untuk truthing tanah, dan (4) analisis data. Hasil menunjukkan bahwa totaldaerah penelitian adalah 13.315 ha terdiri dari 2.892 ha hutan non - sagu dan 10,423 ha hutan sagu. Hutan sagu dibagi menjadi 3 strata, yaitu kepadatan rendah, kepadatan sedang, dan kepadatantinggi, yang memiliki luas wilayah 630 ha, 392 ha, dan 9.401 ha. Populasi sagu matang di kepadatan rendah , kepadatan sedang , dan kepadatan tinggi 22,680 berdiri , 32,928 berdiri , dan 549,018berdiri sebesar 4.930 ton , 7,226 ton , dan 109,044 ton pati sagu , masing-masing. Sehingga , total saham sagu di daerah penelitian adalah seluruh 121,200 ton pati sagu.

Sago palm is a tropical plant which not only grows in the dry lands but also grows with high adaption to low-lying wetlands such as fresh waterswamp, peat swamp or brakish water. The origin of sago palm is believed to be the area extending from Moluccas, and Papua of Indonesia to New Guinea. However, the attention to explore spreadand potential of sago stock has not been done adequately in Papua. The Objective of this study is to develop spatial statistics method for mapping and estimating sago stock in Inanwatan District,Sorong Selatan Regency, West Papua. Area frame sampling of square segment method is applied for estimating sago stock, which involves some stages, i.e., (1) Stratification of study area by usinghigh resolution of satellite data, (2) Design of sample frame survey, (3) Field survey for ground truthing, and (4) Data analysis. The Results show that the total of study area is 13,315 ha consistedof 2,892 ha non-sago forest and 10.423 ha sago forest. Sago forest is divided into 3 strata, namely low density, medium density, and high density, which has area of 630 ha, 392 ha, and 9,401 harespectively. The population of ripe sago palm in low density, medium density, and high density are 22.680 stands, 32.928 stands, and 549.018 stands equal to 4.930 tons, 7.226 tons, and 109.044 tonsof sago starch, respectively. So that, the total sago stock in the whole study area is 121.200 tons of sago starch. Keywords: spatial statistics, area frame sampling, remote sensing, sago palm
