Cempaka Diamond Mining

The Eternal Footprint of Earth's Gems: History and Existence of Cempaka Diamond Mining

Cempaka Diamond Mining is not just a traditional mining site in South Kalimantan; it is a living monument that records the pulse of the economy, social resilience, and geological wonders of the Banjar land. Located in Cempaka District, Banjarbaru City, this site is one of the oldest diamond mining centers in Indonesia that still operates today with methods virtually unchanged for centuries.

Historical Origins and Formation Period

Diamond panning activities in Cempaka are estimated to have begun since the Banjar Sultanate era, long before the Dutch colonialists established their influence in the Southeast Kalimantan region. Geologically, the Cempaka area sits atop rock formations rich in alluvial deposits, where pure carbon crystals or diamonds have accumulated over millions of years.

In the 18th and 19th centuries, Cempaka became a magnet for fortune seekers. Local communities developed the "panning" technique using a traditional cone-shaped tool called a linggangan. History records that the fame of diamonds from Cempaka once attracted traders from India, Arabia, and even Europe, who sought high-quality gemstones with superior hardness and clarity compared to diamonds from other parts of the world.

Landscape Architecture and Traditional Construction Methodology

Unlike static historical sites consisting of buildings, Cempaka Diamond Mining is a cultural landscape site. The dominant structures here are manual excavation pits called "rat holes" (lubang tikus). The depth of these holes can reach 10 to 15 meters below ground level.

The construction of the holes was done with very precise traditional calculations to prevent collapse. The panners used galam wood (Melaleuca cajuputi) as the main support inside the ground. Galam wood was chosen for its unique properties: the longer it is submerged in water underground, the stronger its fibers become and the less prone to rot. These support structures were built like vertical frames to hold the soil walls, allowing workers to descend to the bottom of the hole to extract the soil layer containing diamonds (called karangan soil).

Historical Significance and Monumental Events

The most phenomenal event in the history of this site occurred on August 26, 1965. A group of panners led by H. Madlam discovered a giant diamond weighing 166.75 carats. This diamond was later named "Intan Trisakti" by the first President of the Republic of Indonesia, Ir. Soekarno. This discovery shook the international diamond world and solidified Cempaka's position as a world-class diamond producer.

Besides Trisakti, several other major discoveries mark important history, such as Intan Galuh Cempaka (106 carats) in 1846 during the colonial era, and Intan Putri Malu discovered in 2008. Each major discovery is often associated with mystical narratives and local wisdom, where the community believes that diamonds are "beings" that only reveal themselves to those with pure hearts.

Figures and Connections to the Colonial Period

During the Dutch colonial period, the colonial government attempted to modernize mining in Cempaka through the company Oost-Indische Ontginning Maatschappij. However, these industrialization efforts often failed to compete with the efficiency and sharp instincts of traditional panners. Local panners, often referred to as "Galuh" (an affectionate term for undiscovered diamonds), possessed a knowledge of soil taxonomy that Western geologists at the time lacked.

Figures such as the leaders of the panning groups (Ketua Kelompok) played an important role in the social structure of this site. They were not only work organizers but also custodians of customs that maintained harmony between humans and nature in the mining area.

Preservation Status and Conservation Efforts

Currently, Cempaka Diamond Mining is managed as a Cultural Heritage Site and Historical Tourist Destination by the Banjarbaru City Government. Although mining activities are still actively ongoing (making it a living heritage), significant challenges arise from environmental aspects and modernization.

Preservation efforts are focused on protecting traditional methods from being eroded by the excessive use of mechanical pumps. The local government has built supporting infrastructure such as observation towers and information centers to educate tourists about the long history of diamonds in South Kalimantan. Restoration here does not mean repairing buildings, but rather maintaining the social and technical ecosystem so that the panning ritual remains authentic according to ancestral traditions.

#

Cultural and Religious Significance

Panning for diamonds in Cempaka is not merely a livelihood but a cultural practice imbued with spiritual value. There are codes of ethics and taboos (pamali) that must be adhered to. For example, the prohibition of saying the word "diamond" while at the site (replaced with the term "Galuh"), the prohibition of whistling, or the obligation to maintain purity of speech.

The religious community of Cempaka blends local beliefs with Islamic values. Before undertaking new pit excavations, a joint prayer ritual is usually performed to ask for safety and blessings. This indicates that the site is a meeting point between economic exploitation, noble traditions, and spiritual devotion.

Unique Historical Fact: The "Breathing" Diamond

One rarely known unique fact is the belief among panners that diamonds in Cempaka are "alive." They believe that diamonds can move or disappear if the panners act greedily or dishonestly. Technically, this refers to the shifting of alluvial soil layers due to underground water currents, but sociologically, this belief functions as social control to maintain honesty among fellow panners in the division of results.

Cempaka Diamond Mining remains a symbol of South Kalimantan's identity. It is a reminder that behind the world-renowned sparkle of gems lies the sweat, courage, and long history of thousands of people who depend on the generosity of the Banjarbaru earth. As a historical site, Cempaka offers a narrative about the resilience of a tradition that has traversed various eras, from the sultanate, colonial, to modern independence.
