Some groups of renewable natural resources are agriculture, plantation, forestry, animal husbandry and fishery.
a. Agriculture
In Indonesia, agriculturefarming is the very basic work of the people. There are two agricultural forms in Indonesia, namely wetland and dryland farming. Wetland agricultural business can only be
done in areas that are rich in water reserve and usually occurs in lowland areas. Dryland agricultural business is a type of farming that is conducted in the lacking of water reserve areas. It usually occurs
in the hilly areas.
In general, dryland agriculture consists of irrigation rice field, tidal land, rainfed rice field, and
valley rice field. Irrigation rice field gets regular watering from the irrigation so it does not depend on the rainwater. The harvest can be done three times a year. Tidal rice field usually occurs in lower
course and shore side. It is planted during the low tide. Banarawa is a rice species that usually planted in this area. It can be found easily in Riau, around Barito lower course in Borneo, and around some
lower courses of big rivers like in Palembang and Jambi. Rainfed ricefield is one which watering depends a lot on the rainwater. It is usually harvested once a year. The valley rice field occurs in the
left and right sides of a river. Dryland farming in Indonesia can be done by cultivating upland un-irrigated field berladang,
cultivating secondary crops in dry fields bertegal, and gardening. Upland agriculture berladang
is processing the land by clearing forests or shrubs. The forest that has been turned into a rice field can
only be planted for a few times. After its fertility reduced, it will be left and the farmers will look for
another or clear another forest. The commonly planted rice type is Gogo. The business of this
shifting farming is disadvantageous as it can destroy the forest ecosystem, accelerate erosion and
accelerate the depletion of soil nutrient. Bertegal
is a farming activity in the dry land that depends a lot on the rainwater. The products are
rice, cassava, sweet potato, corn, pulses, horticulture, or vegetables and fruits.

Supplementary Information The system of Seven Exertion Farming that is worked by the government to improve farming consists
of the following: 1.
managing the land to maintain its sustainability 2.
watering or irrigating 3.
using the super seedlings 4.
fertilizing to fertilize the land 5.
eradicating of pest and disease, and 6.
marketing of crops. Farming products as natural resources of Indonesia are as follow:
1. Rice as the main food after turned into cooked rice.
2. Corn is the secondary food. It grows well at 0 up to 1,500 meters above the sea level and of 17
o
C up to 25
o
C temperature. Some of the corn producer regions are Madura, East Java, Yogyakarta, Lampung, Nusa Tenggara Barat, Nusa Tenggara Timur, South Sulawesi, and
Gorontalo. 3.
Sago is a plant from Ambon. It is the main food in Moluccas and Papua. It grows well in Moluccas, Papua, Riau, and West Borneo. It is also used as cake ingredient, while its leaves can
be used as roof. 4.
Cassava can grow almost in all parts of Indonesia. The producers are Lampung, West Java, Middle Java, Yogyakarta, East Java, Nusa Tenggara Barat and Nusa Tenggara Timur. Cassava
can be processed into dried cassava gaplek, tapioca and various foods. 5.
Soybean is a plant that grows well in dry land like in tegal, ladang upland, and house’s yard. It is cultivated in Lampung, Middle Java, East Java, and Nusa Tenggara. It has many functions, for
example it can be processed into tofu, tempe, soy sauce, frying oil, milk powder, and mixed fodder.
6. Nut is a pulses plant which is rich in vegetable protein. It is cultivated in dryland, upland and rice
field during the dry season as the rice alteration. The producers are Java island and Celebes.
