Distance (Ricinus communis) is a wild plant a year (annual) and is usually found in forests, vacant land, in coastal areas, but often also bred in plantations. This plant is classified as a shrub plant, has a single leaf perched between 7-9, 10-40 cm in diameter. This plant is a plant species of Euphorbiaceae and belongs to the genus Ricinus, subribe Ricininae.
The term for jatropha in Indonesia varies from region to region. In West Java it is called 'Kaliki'. In Sumatra, distance is known as Dulang and some people call it Gloah. In Madura, distance is called Kalĕkĕ.
The benefits
Parts of jatropha plant that can be used are seeds, roots, leaves, and oil from the seeds. In general, almost all parts of jatropha plant can be used as medicine. the leaves are used as a remedy for ulceration, eczema, itching (pruritus), coughing and hernias. .the root part is used for rheumatic joints, tetanus, epilepsy, bronchitis in children, wounds, TB glands and schizophrenia (mental disorders). the seed part is used to reduce difficulty in defecation (constipation), cervical and skin cancer (carcinoma of cervix and skin), visceroptosis / gastroptosis, difficulty in giving birth and retained placenta / placenta, facial muscle paralysis, tuberculosisglands, ulcers, ulcerations, scabies, fungal and swollen infections.castor seeds also produce an oil called castor oil or ricin oil. Castor oil in general, is often used for industrial, medical and military purposes. in Indonesia, castor oil is used for the paint industry, textiles, synthetic fibers, medicines, to cosmetics and rocket fuels.

This plant is a source of castor oil, and contains the substance ricin, a type of deadly poison. Jatropha is the only plant whose seeds are rich in a hydroxy fatty acid, namely ricinoleic acid. the presence of these fatty acids makes castor oil have a stable viscosity at high temperatures so that castor oil is used as a lubricant mixture. Castor oil which has heat-resistant properties, has been widely favored and ordered by the cosmetics processing industry, pharmaceuticals, paint factories, plywood industry, textiles, and others, both from within and outside the country. in developed countries, castor oil is used by the military as aircraft lubricants and explosives. In addition, castor oil is also used as a material for producing synthetic soap, nylon, ink, varnish and paint. Until now, castor beans are still needed in Indonesia by pharmaceutical companies, paint oil producers, and putty boat glue, although domestic production of around 12,000 tons a year has not been able to meet the needs of castor beans.

Indonesia Soursop fruit is also called jackfruit or Dutch durian with the Latin name Annona muricata L, is a plant rich in benefits that come from the Caribbean, Central America and South America. Soursop Saun contains Acetoginin (Bulacin, Asimisin and Squamosin) compounds. This acetoginin in high compounds functions as an anti-feedent. Even pests are reluctant to eat soursop tree leaves, in low concentrations can cause insect pests that eat them will die.
Soursop is a plant with a tree height of about 8 meters. Woody brown stalks, rounded, branched. .have an egg-shaped or lancet leaf, pointed tip, flat edge, tapered base, pinnate reinforcement, 5 mm stem length, yellowish green. flowers are located on stems or twigs, small petal leaves, yellowish white, many hairy stamens. .the fruit is not true fruit, which is called "fruit" is actually a collection of fruits (aggregate fruit) with a single seed that coincide with each other and lose the boundary between the fruits. Soursop flesh is white and has black seeds. light brown roots, rounded with tap roots (Syamsuhidayat and Hutapea, 1991). Soursop leaves contain acetogenin compounds, essential oils, reticuline, loreximine, coclaurine, annomurine, higenamine.

Soursop fruit contains a lot of carbohydrates, especially fructose. Other nutritional content is vitamin C, vitamin B1 and vitamin B2 which are quite a lot. Seeds are poisonous and can be used as natural insecticides, as are sugarcane seeds. Soursop leaves are beneficial to inhibit cancer cells by inducing apoptosis, antidiarrheal, analgesic, anti-dysentery, anti-asthma, anthelmitic, blood vessel dilation, stimulate digestion, reduce depression (McLaughlin, 2008).

Teak tree is a type of high-quality wood-producing tree with a large tree, straight trunk, can grow to reach a height of 30-40 meters.
It also has large leaves that fall in the dry season.
this plant which has the scientific name Tectona grandis.L.F can be used as a material for making boats, flooring, furniture, cabinets, musical instruments, railroad pads, bridge poles, girder houses and so forth.
This teak tree is a typical vegetation of the season forest.
This season's forests are found in areas that have clear seasonal changes, which are the dry season and the rainy season.

it also has a relatively long dry season period. In general, during the dry season, vegetative plants forest season will drop leaves or molt.
this is done to reduce the high rate of evaporation in plants.
One example of plants that molt during the dry season is teak.
in addition to shedding the leaves during the dry season, this season's forest also has another characteristic, namely that the forest area is dominated by one main plant species or what is called a homogeneous forest. most people are certainly familiar with the name of teak tree. Teak tree has strong wood and can be utilized for various things such as to make a house.
Usually in the dry season the leaves of this tree will dry out. plants that can only grow in tropical rain forests with temperatures ranging from 27 - 300C and the growth rate is slow.
Therefore it takes a long time to be utilized. as for some of the advantages that characterize teak wood, namely:
The wood of this teak tree is strong and large with a diameter of about 200 cm
This teak tree is durable if used for making goods
has a yellowish brown brown bark with a cracked texture according to the elongated, loose and scaly grooves.
The leaves are facing, pointed and short-stemmed with a rough green upper leaf. while the bottom leaves are yellowish green and downy and include red hairs that develop when the leaves are damaged or damaged.
teak trees usually bloom every year with a heavy start at the beginning of the rainy season and if enough water can flower in the dry season (in watersheds).

Sapodilla called neesbery or sapodilas are fruit plants in the form of originating from Guatemala (Central America), Mexico and the West Indies. but in Indonesia, sapodilla plants have long been known and widely grown from lowlands to places with an altitude of 1200 m above sea level, such as in Java and Madura. Sapodilla plants in plant taxonomy are classified as follows:
division: Spermatophyta (Seed plants)
Subdivision: Angiosperms (Covered seeds)
Class: Dicotyledonae (Double-eyed seeds)
Order: Ebenales
Family: Sapotaceae
Genus: Achras or Manilkara
Species: Acrhras zapota. l are synonymous with Manilkara achras. The benefits of sapodilla are as fresh fruit food or processed food ingredients such as ice cream, jam, syrup or fermented into wine or vinegar. In addition, other benefits of sapodilla plants in human life are:
a) Green plants on dry and critical lands.
b) Ornamental plants in pots and living pharmacies for the family;
c) Gum-producing plants for the raw material for the gum industry;
d) Timber plants which are very good for making household furniture.
