| The Spectacular Blue Fire Phenomenon of Ijen Crater |
Ijen Crater in Indonesia is famous for its beautiful blue fire phenomenon. A rare natural wonder that is hard to find anywhere else in the world. This enchanting crater lake is located at the peak of Mount Ijen, a 2,769-meter-high volcano, on the border of Banyuwangi Regency and Bondowoso Regency, East Java, Indonesia. Located at an altitude of 2,386 m, Ijen Crater stretches over 722 m², with a depth of up to 200 m. Inside this crater we can witness the very beautiful blue fire. However, it is not this very large crater lake that is the main destination for visitors, but the blue fire inside it.
The Enchanting Blue Fire Phenomenon
To be able to witness the enchanting blue fire phenomenon of Ijen Crater is not easy, because this natural wonder can only be seen in total darkness, without any light. Therefore, the blue fire phenomenon can only be witnessed after midnight, until before dawn, which is around 02.00 to 04.00 local time. While darkness envelops the surrounding nature, the Ijen Crater will begin to show its beauty, where the enchanting blue fire will appear to dance in the darkness of the night.

The Process of Blue Fire
Unlike its name, blue fire is not real fire. Blue fire is the result of a reaction between sulfur-rich gas and air, resulting in a bright blue glow in the darkness. Sulfur gas will rise to the surface through cracks in the crater of the mountain, due to high pressure and temperatures reaching 600 ° C. When in contact with air, these gases will ignite, illuminating the darkness with a dazzling electric blue light. The bright blue fire reaches a height of up to 5 m. While some of the burning sulfur gas evaporates into the air, some will condense into liquid sulfur that flows down in a burning state. This extraordinary phenomenon gives the illusion of a blue lava flow flowing down the slopes of the mountain.

The Uniqueness of The Blue Fire of The Ijen Crater
Although the blue fire phenomenon can be found in other volcanic areas rich in sulfur, the blue fire in the Ijen Crater is the most spectacular. In addition, the blue fire of the Ijen Crater can be seen more clearly and continues continuously. Another example of the blue fire phenomenon that has occurred was recorded in the Yellowstone National Park area, USA, where forest fires that occurred melted sulfur, resulting in a river of blue fire that glowed in the darkness.
The Charming Ijen Crater Lake

It is not only the blue fire that makes the Ijen Crater famous and able to attract many visitors, inside the Ijen Crater there is also a beautiful lake with blue-green water. The lake known as the Ijen Crater Lake is famous for its water which has a very high acidity level, so it has been named the largest crater lake with a high acidity level in the world. The water on the edge of the lake has a pH level of 0.5, while in the middle of the lake the acidity level of the water can reach 0.13.
Ijen Crater Sulfur Mining
The Ijen Crater, which is rich in sulfur, is a mining location for local residents. A network of ceramic pipes channels volcanic gas from the crater, facilitating the production of liquid sulfur. After being cooled and hardened, the sulfur is then harvested and sold. Miners work every day collecting chunks of sulfur without caring about the risk of volcanic smoke that is dangerous to breathing. They tirelessly travel more than 3 km across dangerous terrain carrying pieces of frozen sulfur weighing tens of kilograms. These workers endure the dangers of descending steep mountain slopes to earn money. Their resilience and determination are evidence of their daily struggle to survive.

The Danger of Toxic Gases in Ijen Crater, Especially During The Rainy Season
Ijen Crater in East Java is indeed famous for its blue fire phenomenon and natural beauty, but behind its charm, there are dangers of toxic gases that must be watched out for, especially during the rainy season. One factor that worsens this condition is the lack of sunlight which makes it difficult for toxic gases to evaporate. The more humid air during the rainy season makes the gas tend to stay longer near the ground surface, increasing the risk of exposure for climbers and miners.

| The dangers of poisonous gas from Ijen Crater |
Toxic gases that are often found in Ijen Crater include carbon monoxide (CO) and hydrogen sulfide (H₂S). Carbon monoxide is an odorless and colorless gas that is very dangerous because it can replace oxygen in the blood, causing symptoms such as dizziness, weakness, and loss of consciousness. Meanwhile, hydrogen sulfide, which has a pungent odor like rotten eggs, can attack the respiratory system if inhaled in large quantities, even triggering serious poisoning.
During the rainy season, the wind around the crater also becomes unstable, so that toxic gases can spread to a wider area. These dangers are often not realized, until the victim feels the direct effects, such as difficulty breathing, sore eyes, or even fainting. Therefore, before visiting the Ijen Crater, prepare yourself well, especially avoid visiting during the rainy season. Avoid approaching active gas sources, and always follow the guidance of local guides. Understanding these dangers and taking precautions will help us enjoy the beauty of the Ijen Crater safely.

• Preparation of equipment is very necessary to face the challenging conditions of the crater. Make sure to bring a bright flashlight or headlamp to illuminate the dark hiking trail. Bring warm clothes because the temperature in the Ijen area in the early morning can be very cold, even reaching below 10°C. Also wear comfortable hiking shoes to support the journey on rocky terrain. Don't forget to prepare a camera to capture this phenomenal moment.
• For beginner climbers, hiring a local guide is a wise move. Experienced guides not only help you find the best path to the crater, but also provide valuable information about natural phenomena in the area. Local guides also ensure our safety, especially in dangerous areas such as the steep crater rim.
• Good physical condition is essential for climbing the Ijen Crater. The hiking trail is quite challenging, with a 3-kilometer uphill and rocky track that requires stamina and concentration.
