Land capability classification has been used for land evaluation for various purposes in many countries in the world. Since developed by the United States Department of Agriculture as a part of the programme to control soil erosion, the land capability classification has been further developed by a number of authors in many countries to suit their requirements. Of the numerous land capability classification have been published, fourteen are selected to be reviewed. The results shows that the aims of the various land capability classification schemes are generally similar: to evolve methodology whereby land may be evaluated for a particular land use purposes. Most of the methodologies were designed mainly for evaluating the capability of land for agriculture, either in narrow (specific) or in broad terms (including forestry, pasture, etc). Three methods of evaluation of data can be identified: Firstly, descriptive methods whereby capability classes or other categories are descriptive solely in words. Secondly, rating, grading or indexing system whereby each attribute is assigned a rate, grade or index and the capability class or other category is defined in terms of the sum of the weighted scores. Thirdly, quantitative methods whereby the relationships between variables are defined in terms of an equation used to obtain a score or index which defines the capability class or other categories. The capability methods also vary both as hierarchical systems and in terms of the number of categories used. They are also vary in terms of scale, and some do not even specify the scales used. Although substantial differences are found among the methodologies in terms of their purposes and detailed procedures, these are all broadly similar in terms of the general approach and activities involved.

Post-mining land has generally unfavourable characteristics for a growing media for crops. The objectives of the present study were: (1) to study natural changing of soil physical and chemical properties and natural vegetation of four different ages of tailing, (2) to study rehabilitation technique of post mining tailing for forest crops, and (3) to study effects of ameliorant on soil physical and chemical properties, and heavy metal content on four different ages of tailing. Analysis of tailing characteristics, in situ natural vegetation analysis and two sets of green house experiments had been done. The two greenhouse experiments comprise: (1) tailing from Sungai Liat Bangka with two factors, those are three level applications of organic matter and mineral soil with teak as an indicator plant and (2) tailing from Dabo Singkep with treatments: tailing + compost 9:1,tailing + animal manure 9:1 and tailing as control, CMA inoculant and forest trees akasia (Acacia auriculiformis), gamal (Gliricidia maculata), lamtoro (Leucaena leucocephala) and sengon or jeungjing (Paraserianthes falcataria). The result showed that: generally, tin mining reduce soil quality and number of natural vegetation. The soil characteristics and number of vegetation are generally increase (getting better) with time. The first greenhouse experiment showed that the best response of teak plant was under combination of organic mater and soil mineral whereas ameliorant proportion factor is not significantly different. The second greenhouse experiment showed that the treatments were significantly influencing canopy diameter, leaf number, root length and tree trunk circle, respectively. The best rehabillitation technique was combination of animal manure, mycorrhizal inoculants treatments and lamtoro (L. leucocephala). Soil characteristics and heavy metal contents were significantly influenced by ameliorant and tailing ages. Soil chemical properties were significantly influenced by tailing age, types and proportions of ameliorant. The Fe, Mn, Cu, Pb, and Sn of soil were significantly influenced by tailing ages and the highest was on the six years tailing.

Indonesia memiliki kondisi alam yang tergolong rawan terhadap bencana alam. Penyebab terjadinya bencana di Indonesia bisa disebabkan oleh faktor alam dan faktor manusia. Adapun faktor manusia berupa penerapan penggunaan lahan tidak mempertimbangkan karakteristik bentang alam. Kabupaten Kuningan merupakan salah satu wilayah administratif yang terkena dampak bencana (banjir) akibat penggunaan lahan yang tidak mempertimbangkan karakteristik bentang lahan. Tujuan penelitian ini adalah untuk mengetahui kesesuaian antara pola ruang RTRW Kabupaten Kuningan (2011-2031) dengan daerah bahaya bencana banjir di Kabupaten Kuningan. Metode yang digunakan pada penelitian ini yaitu Analysis Hierarchy Process (AHP) dan pairwise comparison untuk penentuan skor faktor penyebab banjir dan longsor, interpretasi citra Sentinel visual tahun 2018 untuk menentukan penggunaan lahan di Kabupaten Kuningan serta metode analisis spasial melalui teknik overlay untuk menentukan daerah bahaya banjir dan longsor. Hasil penelitian menunjukkan bahwa faktor bahaya banjir yang mempunyai bobot terbesar hingga terkecil menurut para pakar berturut-turut adalah curah hujan, kemiringan lereng, penggunaan lahan, jenis tanah, dan elevasi. Bahaya banjir dan longsor terdiri atas 3 kelas, yaitu rendah, sedang, tinggi. Hasil overlay antara faktor-faktor penentu bahaya banjir menunjukkan bahwa: a) Bahaya banjir kelas rendah memiliki luasan 42.771 ha; b) Kelas sedang memiliki luas 48.034 ha; c) Kelas tinggi memiliki luas 28.767 ha. Kesesuaian pola ruang pada kawasan budidaya dengan kelas bahaya banjir menunjukkan bahwa kawasan permukiman perdesaan pada kelas bahaya sedang memiliki luasan tertinggi sebesar 7.998 ha. Pada kelas bahaya tinggi, pertanian lahan basah memiliki luasan tertinggi yaitu 7.646 ha.

The management of nucleus smallholder oil palm after conversion is mostly improper with the promoted management practice, consequently oil palm yield decreases due to decreasing of land quality. For this reason, the study has been done to characterize land condition, to assess land suitability for oil palm and to correlate soil properties against oil palm yield. The study was conducted at Sei Pagar, Kampar District, Riau Province from January 2007 to March 2008. Soil erosion was estimated using Universal Soil Loss Equation, while land suitability was processed using Land Evaluation Technical Guidance for Agriculture Commodities, and correlation of soil properties to oil palm yield was calculated using Multiple Regression Analysis on SPSS Version 12.0. The study showed that climate conditions was favorable for oil palm growth and production, with annual rainfall 2,339 mm year-1, air temperature 26.04oC, and relative humidity 81.2%. Soil erosion varied from 1.322-3.423 t ha-1 year-1. The soils were dominated by Typic Haplosaprist and Terric Haplosaprist covering 8,641 ha with land suitability of S2-f (moderately suitable with nutrients retention as limitng factor). The other soil are Humic Dystrudepts and Typic Dystrudepts covering 587 ha with land suitability of S2-f,n (moderately suitable with nutrients retention and nutrient supply as limiting factors). The soil properties of Typic Haplosaprist and Terric Haplosaprist affected to oil palm yield are organic-C, nitrogen content, P2O5 content, and available-S. Meanwhile, on Humic Dystrudepts and Typic Dystrudepts, oil palm yield was affected by organic-C, nitrogen content, available-S, and aluminum content.

The objectives of the research were to study: (1) the influence of peat and paddy straw compost on crop growth and production, and (2) the influence of residual effect of peat and paddy straw compost application on soil chemical characteristics. The research was conducted at Cikembang, Sukabumi; Cikabayan, Kampus IPB Darmaga, Bogor; and Rasau Jaya,Pontianak, respectively. Soil analysis was conducted at soil laboratory of Department of Soil Science and Land Resource, IPB and Soil Research Centre, Bogor. The research area was degraded grass land located at 300 m above sea level with slope less than 15%. Factorial Design with two replications was used with soybean var. Slamet as an indicator crop. Treatments comprise peat and paddy straw compost, each with five dosesi.e. for peat : 0 t ha-1, 7 t ha-1, 14 t ha-1, 21 t ha-1, and 28 t ha-1, respectively and for paddy straw compost 0 t ha-1, 10 t ha-1, 20 t ha-1, 30 t ha-1, and 40 t ha-1. Observation was carried out for crop height, grain dry weight, and soil chemical characteristics after harvesting. The results showed that application of peat and paddy straw compost significantly increased crop height and production of soya bean. Application of single 40 t ha-1 paddy straw compost significantly increase the highest grain dry weight. The rehabilitation effort was also increase soil fertility status. Residue of paddy straw compost and peat application was significantly increase soil chemical characteristics i.e.: organic-C, N, P2O5, K2O, Ca, Mg, and Base saturation of the soil. The highest N, P2O5, K2O, Ca, Mg, CEC, and base saturation of the soil was found in application of single paddy straw with doses of 40 t ha-1. Application of paddy straw compost fordegraded land increased soya bean production and rehabilitated of soil condition better than application of peat.
