Aquatic areas in Indonesia are rich in food sources for various types of plants, fish, and marine animals, and also contain various types of mineral sources.
Indonesia is also known as an agricultural country because most of the Indonesian population has a livelihood in agriculture or farming. In February 2016, the Central Statistics Agency (BPS) recorded 31.74 percent of the workforce in Indonesia or 38.29 million working in the agricultural sector. Here are some types of agriculture in Indonesia.
Irrigated rice fields are fields that obtain irrigation from technical irrigation in the form of an irrigation system whose water comes from an artificial lake (river dam, made a good and regular water channel and then flowed into the rice field). Irrigated rice fields also have simple irrigation made by village farmers.
Rice fields have lots of water. Wetland farming is often carried out in areas that have plenty of water reserves. In general, wetlands in the country of Indonesia experience various pressures towards destruction. Forest conversion, illegal logging, and forest fires are the main threats to wetland agriculture. Many communities depend on wetland agriculture.
Non-irrigated rice fields are rice fields that obtain irrigation technically. It usually grow with a little of water even no water at all. It can be divided into:
3. Field (Huma)
Agriculture with a field system (huma) is agriculture in dry land, as well as moor and gardens (yards). Field (huma) is an agricultural system by opening forests. The way is, the forest is cut down and then burned and cleaned. Only in the rainy season is it planted. After 3-4 times of harvest and reduced fertility, the field is abandoned and usually overgrown with grass and grass.
Farmers are looking for more forest to cut. The field system can cause environmental damage, for example many forests are damaged, water absorption is reduced, soil is deforested, fertility is reduced, eventually causing flooding. Plants planted in fields (huma), namely upland rice, corn, and nuts.
It is agricultural activities with moving land, which is usually done on a lot of land resulting from the opening of shrubs after several times of planting and also harvesting will move the land again. If the land is no longer fertile, it will move the land again looking for other fertile land.

Hydroponic agriculture is a farming activity that uses water without using soil. This method is done because it aims to emphasize the nutritional needs for plants. In addition, the water needs for this type of farming activities are also less than other types of farming activities. This type of activity is very suitable to be applied for areas that have limited water supply.
Modern agriculture is a type of farming activity that is currently often applied in various walks of life in Indonesia. In addition to being efficient, this type of activity is also very easy to do compared to other farming activities.
The use of various modern tools, and also the use of various kinds of chemicals in their application become prominent features in this farming activity. But there are some disadvantages of this type. In addition to endangering consumers, the use of chemicals can also damage existing natural ecosystems.

Simply put, gardening can be carried out in the yard of the house. This is done to utilize vacant land and increase income. In the countryside, garden farms are generally quite extensive. Land is planted with commercial crops, both for export commodities and for sale domestically, for example rubber and chocolate.
To enhance the welfare of these commercial crop farmers, the government has carried out various efforts, among others through community nucleus plantations (PIR). PIR is embodied in a program of agricultural land expansion by integrating small-scale agricultural businesses..
Horticulture is part of dryland agriculture. The types of plants that are usually sought include vegetables, fruits, or flowers. Several objectives of activities to increase agricultural yields, reduce the risk of crop failure, maintain soil fertility.
Horticultural plants are much sought after by residents who live in highland areas because the air temperature is relatively cool, which is at an altitude of 500-1,500 meters above sea level. Regional distribution of horticultural agriculture in Indonesia, including Lembang, Pangalengan, Puncak (West Java), Wonosobo, around Dieng (Central Java), Malang (East Java), and Tanah Karo (North Sumatra).

9. Dry Fields
Dry field or usually called Tegalan in Bahasa Indonesia is a continuation of the farming system, this happens if the forest that might be opened for agricultural business is no longer possible. Moor farming land is already settled. Cropping patterns are usually mixed or intercropped between rice fields and pulses (maize, beans, cassava, etc.).
In dry fields, it is usually only cultivated in the rainy season, while in the dry season there is no (left) plant. On tegal land, efforts to preserve productivity already exist by means of fertilization, although it is limited when planted alone, while conservation then goes naturally, or allowed to grow wild plants, which are subsequently cleared when replanted with economic crops. This land productivity is generally low and unstable because the state of the topography is not flat and is not limited by dike or erosion resistant swales.
Shallow marine ecosystems in warm waters with sand bottom and dominated by seagrass plants, a group of plants belonging to Alismatales who adapt to saltwater. Seagrass beds can only form in shallow sea waters (less than three meters) but the bottom is never open from the water (always inundated).
Sometimes, seagrass vegetation is found after mangrove vegetation and its function can act as a filter of mud / soil that is washed away with water to the beach after being able to escape retained by the roots of mangrove vegetation. Seagrass beds can also be seen as ecosystems between mangrove ecosystems and coral reefs. In Komodo National Park, seagrass is the main source of dugan’s feed.
Those are the types of agriculture in Indonesia. In this term, this country plans to make a significant growth in the production of agriculture. It is possible that Indonesia would be the center of economical of the world.
