MOUNTAIAN TOURISM IJENIjen Crater Tourism Region is located in the middle of nature reserve area Ijen
crater which is in the Bondowoso District, District Klobang and Banyuwangi, Sub Smooth. This crater form tosca green lake at an altitude of 2368 meters above sea level. Caldera crater walls as high as 300-500m. Lake Ijen has zero degrees of acidity, has a depth of 200 meters. Acid strong enough to dissolve the clothing and the human finger.
This crater has an area of about 5466 hectares. Water crater was quite quiet and dark bluish green. The scene there looks so amazing in the morning. Water crater volume of about 200 million cubic meters of heat reaching 200 degrees Celsius, it emits a golden glow green when the sunlight hits the back of Mount Merapi, Mount Ijen twins.
To reach the Ijen crater can be done in two ways, namely from the north and the south.
a. Through the north
From Situbondo to Sempol (Bondowoso) through Wonosari then proceed to Paltuding that can be achieved by motorcycle or four wheel. Distance Situbondo until Paltuding is 93 km and the condition of the road until virtually Paltuding very good that can be completed in about 2.5 hours.
b. South road through
From Banyuwangi to the slippery which is about 15 km, which can be passed by motorcycle or four for about 30 minutes. From slippery to Paltuding which is about 18 km journey can be continued with particular types of motor vehicles double-axle jeep for about 6 km before reaching the road Paltuding called erek-erek incline in the form of S-shaped curve and once climbed, the journey takes approximately one hours, because the roads are often damaged by rain water and impassable Sulfur trucks every day.
Resource Inventory Gunungapi
The crater of Mount Ijen volcano has varied resources and potential which includes:
a. Sublimat sulfur.
Sublimat sulfur is a product of Mount Ijen's crater can be used for various purposes in the chemical industry. Sulfur produced from the sublimation of sulfur gases contained in smoke solfatara a temperature of about 200 ° C. Sulfur capacity of an average of about 8 tons / day. Solfatara field located in the southeast of Ijen crater lake.
b. Source hot springs
Hot springs sources of sulfuric acid chloride type with a temperature of 70 ° C and pH around 2, there are 6 solfatara field near Ijen. While hot water with bicarbonate-type neutral temperatures around 45 ° is in the north of the Ijen caldera is the Blawan, District Bondowoso
c. Ijen Crater Lake water
Ijen Crater Lake is a multi-component plant in which various processes occur both physics and chemistry including the release of magmatic gases, dissolving rocks, sedimentation, formation of new material and re-dissolving substances that had been established, resulting in lake water is very acidic and contains dissolved with very high concentrations. Ijen crater lake water can be made gypsum by adding calcium oxide into it. From the results of research ever conducted in BPPTK per 1 liter of water a direksikan Ijen crater with calcium oxide in 100 grams stokiometri produce gypsum.
d. Field gypsum / anhidrit
The formation of gypsum / anhidrit occurred under the Ijen crater dam upstream Banyupait time. Crater lake water containing high sulfate concentration and / or filtered through the rocks to form gypsum. Rocks here serves as a source of calcium. With the process of evaporation / heating at the surface of the gypsum that occurs can lose water to form anhidrit.
e. Mainly volcanic rock pumice
Pumice are found around the crater lake of Ijen especially in the upper Kali Banyupait.
f. Tourism and study objects vulcanology
Mount Ijen Crater Lake in addition to serve as attractive tourism objects are also very interesting to study the geology and geochemistry.
Ijen Crater Tour.
Mount Ijen Crater is one tourist destination in East Java, which is always crowded visited by both domestic and foreign tourists. Natural beautiful mountains and cool, they often start with how to enjoy camping in Paltuding. With a partridge met along the asphalt road show that. keasrian mountains and forests are still well maintained.
On the summit of Mount Ijen crater lake there with its turquoise color and had a very acidic pH. To the southeast of the lake there is a solfatara field wall and Ijen crater lake in the west there Ijen Crater Dam which is upstream from Banyupait time.
Field solfatara Mount Ijen Crater is always releasing volcanic gases with a high concentration of sulfur gases and odor sometimes sting and irritate the respiratory tract is a tourist who never missed to attend, even during the day this place is never quiet because there is always the sulfur miners retrieve and transport / carry sublimat reached Paltuding sulfur.
Ijen Crater Dam is part of interesting tourist objects but not always visited by tourists because of its achievements include the hard road to get there due to frequent landslides due Rusal. Ijen Crater Dam is a concrete building constructed since the Dutch colonial period and is intended to regulate the water level so as not to cause a flood of acid water. But this dam is not working now because the water never reached the door due to the occurrence of water seepage / leakage of water below the dam lake.
Seepage occurrence of this ongoing process of formation of lead occurs from the reaction of gypsum sulphate contained in the lake water with calcium compounds from the water and the calcium of the rocks through which the evaporation process is also accelerating its formation. Ground gypsum can be one of the interesting tourist objects when managed professionally.
