A briquette is a block of combustible material that is used as a fuel to start and maintain a flame. The most commonly used briquettes are coal briquettes, charcoal briquettes, peat briquettes, and biomass briquettes.Briquettes are made by pressing and drying a mixture of ingredients into hard blocks. This method is commonly used for coal that has low calorific value or coal flakes in order to have additional selling value and benefits. Briquettes are used in industry and households.
The material used for the manufacture of briquettes should have a low water content to achieve a high calorific value. The presence of volatile materials also affects how fast the rate of briquette burning; Materials that have high volatile materials will burn out faster.
Coconut is a versatile tree for tropical communities. Almost all of its parts can be used by people.Coconut fruit is a tropical fruit produced from the Cocos nucifera plant, belonging to the Arecaceae or palm-paleman family. Coconuts are round in shape on some sides, slightly angular, about the size of a human head. The color of coconuts is green and some is yellow depending on the variety.
Coconut flesh is wrapped in the outer skin in the form of thick fibers and the inside is hard wood or shell. Coconut shell wraps clean white flesh and fruit juice. The water contained in the clear fruit is slightly cloudy, it tastes sweet and refreshing.
Copra is the dried flesh of the coconut. Copra is one of the most important coconut derivative products, because it is the raw material for making coconut oil and its derivatives. To make good copra, you need coconut that is about 300 days old and weighs about 3-4 kg. After the copra has been extracted, what remains is a by-product which contains high protein (18-25%).
In addition to being used for coconut fruit, coconut can also produce coconut oil. Virgin Coconut Oil is oil that extracted from coconuts without the application of heat. It is rapidly gaining worldwide popularity compared to regular coconut oil and for good reason. In afact, there is a substance called virgin coconut oil and it differs from regular coconut oil significantly. These differences mainly lie in the source (more specifically, the physical from the source) the extraction method and the subsequent benefits.
Coconut oil that can be used is Coconut oil, or Copra oil, is a vegetable oil extracted from the kernel or flesh of mature coconuts harvested from the coconut tree. It has various applications. Due to its high saturated fat content, it is slow to oxidize and as such resistant to rancidity, lasts up to six months.
The part of the coconut that is usually thrown away is coconut husk. Coconut Fiber is a natural fiber extracted from coconut coir and used in products such as floor mats, doormats, brushes and mattresses. Coir is a fibrous material found between the hard shell, inner and outer layers of coconut. Other uses of cocoa coir are as coatings,sacks and horticulture. White coir, harvested from raw coocnuts, is used to make fine brushes, ropes, ropes and fishing nets.
Candlenut (Aleurites moluccana) is a plant whose seeds are used as a source of oil and spices.The oil extracted from the seeds is useful in industry for use as a paint mixture.Candlenut grows well on limestone soils, sandy soils on the coast. But it can also grow on podzolic soils that are less fertile to fertile and on latosol soils. Candlenut plants can grow and produce well at an altitude of 0-800 meters above sea level, although in some places it can also grow at an altitude of 1,200 meters above sea level. Candlenut plants can grow on flat land, bumpy and steep cliffs. Judging from the climatic conditions, candlenut plants can grow in areas with dry and wet climates. Candlenut plants can grow in areas with rainfall of 1,500 2,400 mm per year and temperatures of 200 270C.
The main product of the nutmeg plant is essential oil which can be produced through distillation from raw materials in the form of fruit flesh, seeds, and mace.Indonesia supplies around 60% of the world's total nutmeg market needs every year.Nutmeg plants in general can grow in areas with an altitude of about 0-700 meters above sea level with a fairly high rainfall requirement of 2000-3500 mm / year and humidity of around 50-80%. This plant can grow usually up to a tree height of 5-15 meters or can even reach 30 meters. Nutmeg is suitable to grow at air temperatures around 20-30oC with the structure of the soil where it grows has a large enough range, namely from dense soil to sandy and has an acidity degree of 5.5-7
