Abstract

Upland agriculture plays an important role in producing various kinds of food crops. However, data of the annual upland crops areas that are needed as a basis for area extensification planning is not available. Therefore land area of 10 commodities of annual upland crops was estimated based on its comparison with paddy field areas, with the assumption of cropping index of 100 (one crop per year). For example, upland area planted to maize is assumed 60% of the total harvested area of maize, because the remaining 40% is produced in paddy field areas. Based on these predictions, the upland areas planted to 10 food crops is only about 5.53 million ha or 37.7% of the total annual upland agriculture area of 14.6 million ha. To evaluate the production capacity of the upland areas, we grouped those areas based on soil fertility and potential yield for each commodity. The results indicate that if the 5.53 million ha upland areas are used optimally for food crop production, it can produce 2.82 million tons of unhusked upland rice, 9.15 million tons of corn grain, 0.23 million tons of soybean grain, 0.73 million tons of peanuts pods, 0.20 million tons of mungbeans, 20.81 million tons of cassava, 0.58 million tons of sweet potato, 1.0 million tons of potatoes, 0.21 million tons of shallots and 1.3 million tons of sugarcane. If in the coming year, the total area of upland can be increased gradually from 37.7% to 70% of the total available annual upland areas, i.e. to about 10.2 million ha, thus the upland crops production capacity will increase to 4.9 million tons of upland rice , 16.2 million tons of corn, 0.4 million tons of soybeans, 1.5 million tons of peanuts, 0.35 million tons of mungbeans, 37.3 million tons of cassava, one million tons of sweet potatoes, 1.8 million tons of potato, 0.27 million tons of shallots and 2 million tons of sugarcane. By increasing the upland areas of about 5 million, it will lead to the national selfsufficiency of most commodities until the year of 2050, except for soybeans, potatoes and shallots. Therefore, to maintain selfsufficiency in rice and maize , as well as promote self-sufficiency of other food crop production, the extensification of upland agricultural areas for food crops is a prerequisite.

Abstract

Utilization of ex-mining land for agricultural extensification is an opportunity to solve the problem of food and environment. This paper discusses prospective utilization of ex-mining land for agricultural extensification. Mining area equipped with a business license for mining in Indonesia is around 2.2 million ha under Coal Concession Agreement, and 2.9 million ha under the Contract of Effort. A part of land is already finished being mined, and be managed properly in order to benefit the community and not damage the environment. The initial steps that need to be done is mapping of mined lands, included a status of ownership (land tenure), so that subsequent use of both for agriculture and other businesses can be sustainable. Land reclamation is necessary to increase capacity and efficiency for biomass production. Determination of land use types, should be based on land tenure, bio-physical conditions of land, and the needs of the community or local government. In the future, mining land management requirements is not enough simply by opening a feasibility study for mining operations, but need to be accompanied also with itsclosure plan (planning of closures), which includes environmental protection and mitigation of socio-economic problems. This needs to be one of the terms of the granting of mining permits.

Abstract

Distribution of red soils is about 50 million hectares, and generally potential for agricultural development in Indonesia. The soil was formed from various parent materials, such as andesitic-basaltic rock, acid tuff, limestone, ultra mafic rock, clay stone and sand stone. Generally the red soils were very developed soils, so that the sand mineralogy was dominated by minerals thatresistent to weathering such as quartz and opaque. The clay mineral was dominated by variable charge minerals which depends on pH like kaolinite followed by gibbsite, goethite, and hematite. These soils have very acid to slightly alkaline reaction, low exchangeable bases, low to high cation exchange capacity, and positive correlation to organic-C in the soil. The red soils according to Soil Taxonomy system could be classified as Inceptisols, Alfisols, Ultisols, and Oxisols. Characterization of the red soils areneeded before they are utilized for agriculture.

Abstract

Indonesia has been able to reach self sufficiency for rice, but the problem is decreasing farmer economic value exchange. For that reason besides pursuing increase land productivity and agriculture commodities development, the improvement farmer income must be done. Daerah Istimewa Yogyakarta Province has ± 0,319 million ha within land typology from mountainous vulcanize until sand shore. The problem is narrow land tenure, so that to increase farmer income the development of agriculture commodity with high economics value should be executed based on land carrying capacity. High diversity of land typology with good irrigation network and farm road infrastructure make DI Yogyakarta Province potential to be developed as agriculture seed centre and off season commodity planting. The minerals deposit of volcanous Merapi mountain and marine can increase quality ofagricultural product which good for health, therefore it is potential for development of functional food and improvement livestock reproduction for calf production. Through agricultural product that has high economics value, farmer income and public prosperity are expected to increased.

Abstract

Groundwater is the water contained in soil or rock layer below the surface. Ground water is one of the limited water resources and the damage can give a broad impact, whereas its recovery is difficult. In addition to river water and rain water, ground water also has a very important role, especially in maintaining the balance and availability of raw water for domestic or industrial purposes. In some areas, dependency on fresh water and ground water supplies has reached ± 70%. Lack of understanding on groundwater condition that occurred in the community, arises problems that become the lost and threaten to life sustainability of the community itself. It is necessary for planning the utilization of groundwater that environmentally oriented based on the stage that includes an inventory of potential groundwater, utilization planning, licensing, monitoring and controlling, and conservation of groundwater. Inventoring of potential groundwater utilization planning, licensing, monitoring and controlling should be based on existing procedures so that utilization can be optimized without causing negative impacts.

Abstract

Indonesia which covers 188.2 million ha of land area has great opportunities for soybean expansion. Until now, domestic need for soybean is still complied from import. Soybean is one of the strategic commodities for food and industrial needs, which in 2008 became a national issue because of the scarcity in the market. Therefore, the Department of Agriculture launched a selfsufficiency policy on soybeans targetted in the year 2014 through breakthrough efforts. To support the target, suitable land for soybean has been identified in 17 provinces. The results showed that land suitable for soybeans is around 16.7 million ha, scatteredin various location, namely 4.9 million ha in wetland area, 1.7 million ha in dry land area, 1.7 million ha in plantation area, 2.9 million ha in mix garden area, and 5.5 million ha in grass land area. If 30% of the assumed land suitable for soybeans in ricefield and upland can be utilized, these can produce 2.4 million tons of soybeans with the assumption that the average productivity levels is 1.2 tonnes/ha and once a year planting to maintain the balance of others commodity production. By utilizing 2 million ha of ricefield and upland, soybean self-sufficiency can be achieved in 2015. The development and extensification of soybean planting area should consider land suitability level. Area selection which historically has became soybean production center in 1990 is also has to take into account as well as farmer’s habit in soybean farming system. To accelerate the soybean self sufficiency, the improvement of human resources must be supported in form of assisting, motivation, extention, training, and plot dmeonstration, in order to gain optimal land productivity and technological application. In addition, the government supports are needed for the provision ofproduction facilities, capital, building the marketing chain, as well as conditions to create reasonable prices so that there isincentive for communities to develop soybeans.

Abstract

Available water resources and its quality in Indonesia have been deteriorated as an impact of climate change (and/or) environmental degradation. This could affect on farming processes particularly and agricultural development in general. Virtual available surface water gives a figure that available water decreased temporally and spatially. For instance, in Java island with cover 65% of total population only has 4.5% of the total available water in the country. Agriculture is the biggest use of water (about70%), but it will be difficult for farmers to accomplish water requirements. Other users such as domestic (about 6%), industry (about7%), and municipal (about 4%) are also the major users of water in the country, which may raise a conflict among the users in covering the needs. Current mechanisms to cope climate change in water resources management has been executed through adaptation and mitigation measures for supporting farming system. Integrated water resources management plays critical role in coping climate change. This includes prioritizing water requirements, water harvesting, water conservation, appropriate water allocation, and pollution control. For sustainable farming system development, mitigation strategy should also be included in themechanism covering practices of intermittent irrigation to over come high rate of methane emission. Combining water management and tolerance crops to drought and submergence conditions is very valuable in implementing the mechanisms.

Abstract

In global free trade action, Indonesia has many rivalry constrain to involve on standart product quality need which determined by developed countries from subtropical area. Agriculture product added value based on tropical natural resource is not accommodated proportionally, so that the Indonesian farming system has faced many obstacle resulting low competitive. Competitiveness digging of Indonesian specific land resource is a step in the right direction to do, besides it can increase competitiveness and has protected by regionally regulation. The Indonesian spatial competitiveness are sun energy, rainfall, mineral deposit, diversity of agricultural commodities, geographical position, and agricultural land availability for spell of production. Agricultural production arrangement that considering land capacity and specific competitiveness will increase production efficiency, added value, and selling product. Arrangement of spatial plan of various commodities and correct zonation based on need and location of market will increase competitiveness and farmer welfare. Functional food development, commodity choice, harvest area placement and harvest time arrangement are absolute competitiveness of Indonesian agricultural product and can not be competed by other region.

Abstract

Indonesia mainland has variety of soils, parent materials, landforms, elevations and climates. This condition is the main capitals to produce sustainable agricultural commodities. The utilization of land resources to develop agriculture should consider its potentials in gaining the optimum results. Up to now the agricultural area used for agricultural purposes cover 70.2 million hectares consisting of rice field, upland crop field, yard, plantation, grazing land, trees, and fish pond. Based on the assessment results by Indonesian Agency for Agricultural Research and Development, the land in Indonesia which is potential or suitable for agriculture covers 94 million hectares, comprising 25.4 million hectares of wetland (rice field) and 68.6 million hectares of upland/ dryland. There are 30.67 million hectares of the total area which is potential for agricultural extensification comprising of 8.28 million hectares annual wetland agriculture (rice field), 7.08 million hectares annual upland agriculture, and 15.31 million hectares perennial agriculture. Wetland for annual crops covers swampy land with the total of 2.98 million hectares (mainly in Papua) and non swampy land 5.30 million hectares. In Indonesia the potential land as well as available land for agricultural extensification is still sufficient, but by the increasing needs of land for agriculture and non-agriculture, careful utilization is needed. The landuse competition in the future as a consequences to keep national food security and develop bioenergy needs to be overcome. Some efforts that can be done are by increasing the productivity (intensification), correct landuse based extensification, and developing primary technological innovation.

Abstract

Spodosols characterized by the presence of spodic and albic horizons, are problem soils due to low productivity, coarse texture and low nutrient status. This soil was generally covered by alang-alang or shrub and bush. The soils were generally distributed in cold climate or wet tropical areas with high rainfall. The objectives of this paper were to discuss the characteristics ofSpodosols in Kalimantan and Sumatra and the possibility of their utilization. In Indonesia, this soil is found in Kalimantan, Sulawesi, Sumatra, and Papua Islands. Parent materials of the soils were originated from quartz sand, sediment or acid sedimentary rocks (quartz sandstone) with low nutrients status. Physiographically, the soils were distributed in alluvial plain, colluvial, sand beach, sand dune, tectonic plain and sandstone plateau on elevation of 5 to >1,500 m asl, with flat to nearly undulating relieves. The soil physical properties were characterized by coarse texture and the presence of root limiting layer such as fragipan, duripan, or placic horizon (organo-metal complex) with various depth. The soil chemical properties were characterized by acid soil reaction, very low exchangeable bases, P and K nutrient, and mineral reserve. Cation exchange capacity of the soils depends on their soil organic matter content. Based on the soil characteristics, most Spodosols were not suitable for agricultural land development. Therefore the Spodosols usages should be directed not only for production increases but also for environmental healthiness and soilcare. The Spodosols land that have been opened needs to be optimally used in order to increase soil quality through appropriate soil and plant management. The new land cleared for agriculture and production forest needs carefully actions with localizing the Spodosols distribution in order to maintain the natural vegetations as conservation forest or recreation areas.
