Lombok Pumice Stone Mining Indonesia
Pumice Stone Supplier From Indonesia
The development of Indonesian pumice supply in the period 1985-1991, continued to increase, as follows.
Indonesian pumice production comes from the islands of Lombok, West Nusa Tenggara (NTB) and other areas such as Bali, Lpampung, Bengkulu and West Java. In recent years, in the Ternate area, Maluku, the floating odor has begun to be exploited.
The development of Indonesian pumice production, during the period 1985 – 1991, as a whole showed an increasing trend, from 3,091 tons in 1985 to 127,401 tons in 1988, then increased again in 172,554 tons in 1991. The highest production was achieved in 1990 of 185,461 tons, which means there has also been a decrease in 1991 of 6.96%. The production growth rate during the last five years was 16.78% per year
In the Lombok area, it was recorded that tofu production began in 1987, which amounted to 23,936 tons, and continued to increase to 138,661 tons in 1990 (Table 2). Production in 1991, based on a quota from the government for pumice associations in the area, was 125 tons. In the last three years, the average contribution of pumice production from Lombok, NTB, to all Indonesian pumice production is around 70%.

The number of pumice mining companies in the Lombok area that has SIPD exploitation until 1991 and is still active, is only five. While the others are companies with SIPD processing and sales.
Pumice production from Bengkulu, Lampung and West Java has been started since before 1985. Although in 1989 and 1990 there was a decline in production, during the period 1985-1991, the development of pumice production from these areas still showed an increasing trend. . The increase in production again in 1991 was caused by the start of production again from the Ternate area.
During the period 1985-1991, Indonesia imported only small amounts of pumice, namely from Japan and Taiwan. In 1985 and 1987 there were no recorded imports of pumice.
Imports of pumice in 1986 and 1988 amounted to only 3 tonnes and one tonne, respectively. However, imports of pumice began to increase compared to the previous year, namely in 1989, 1990, and in 1991, respectively, amounting to 259 tons worth 88,725 US dollars, 153 tons worth 49,106 US dollars and 294 tons worth 131,502 US dollars (Table 3). 3).

Pumice Stone Request
The demand for Indonesian pumice consisting of domestic consumption and exports during the period 1985 – 1991 tends to continue to increase as follows:
Consumption of Pumice
In Indonesia, pumice is used for the manufacture of lightweight aggregates such as roof tiles, bricks, culverts for house foundations, and stonewashing in the jean industry. Consumption of pumice in the country during the period 1985-1991, has shown a significant increase. Fulfilling the need for pumice, more than 98% is met from domestic production itself, which is between 10-20% of the production level.
The consumption growth rate from the last five years is 48.59%. Consumption in 1985 was only 697 tons, in 1988 it increased to 17,891 tons, until in 1991 it reached 49.917 tons (Table 4).

The use of pumice in the country, both as the main raw material and as an auxiliary, includes the construction material industry such as roof tiles, building bricks, and for house foundations, especially in areas that have the potential for pumice. Other industries
Those that use pumice are the jean industry (textiles, ceramics, pottery), sculptures, and other art items.
Most (95%) of Indonesian pumice exports are directed to Hong Kong, Thailand, Taiwan, the United States, Singapore, Malaysia and South Korea, while the rest to countries in East Asia, India, Bangladesh, Oman, and others. There are three types of pumice exported, namely 2/3 inch, inch and 5/8 inch. The number of exports annually is about 80-90% of the total pumice produced.
The development of the Indonesian pumice sector, during the period 1985 – 1991, although it has fluctuated slightly, it can be said that it still shows an increase, and in the last five years the average increase is 14.96% per year. In 1985 the export of pumice was only 2,787 tons, in 1988 it was 88,787 tons, and in 1991 it increased again to 106,161 tons. The highest export was achieved in 1989, which amounted to 119,082 tons. When compared with 1989, tahin exports in 1991 decreased by about 10.85%, but increased by 1.28% compared to 1990 exports (Table 5).
