bagaimana proses pengolahan industri garam di ntt

Salt has been used for centuries as a seasoning, preservative, and a source of flavor. Its value in our daily lives cannot be overstated. Today, salt is mainly produced industrially, and this article will focus on the salt production process in Nusa Tenggara Timur (NTT) province, Indonesia.

The Source of Salt in NTT

Salt production in NTT is mainly done in the eastern regions of the province, where seawater is abundant. The salt content in seawater varies from region to region, and in NTT, the salt content is high enough to make it economically viable for large scale industrial production.

Currently, there are three main salt production areas in NTT: Kupang, Alor, and Rote. While Kupang is the most developed area, Alor and Rote are slowly catching up.

The Traditional Salt Production Process

Before the advent of industrial processes, salt production in NTT was done using traditional methods that have been passed down from generation to generation.

The traditional process involves creating salt ponds near the beach, where seawater is allowed to flow in through channels. The salt ponds are designed in a way that enables the seawater to be concentrated by the sun’s heat. The salt crystals that form are then harvested and washed before being sold to consumers.

Although the traditional process is still used in some areas of NTT, it is slowly being replaced by more efficient and cost-effective industrial processes.

The Industrial Salt Production Process

The industrial salt production process in NTT is based on a combination of solar evaporation and mechanical harvesting. The process involves the following steps:

Step 1: Extraction of Seawater

The first step in the industrial salt production process is the extraction of seawater from the sea. The seawater is usually pumped from the ocean and transported to the salt production plant through a system of pipes.

Step 2: Pre-treatment

Before the seawater can be evaporated, it undergoes pre-treatment to remove impurities that may affect the quality of the salt. The pre-treatment process typically involves screening, settling, and filtration.

Step 3: Solar Evaporation

After pre-treatment, the seawater is pumped into large shallow ponds, where it is left to evaporate in the sun. The salt content in the seawater increases as the water evaporates, and salt crystals slowly begin to form.

Step 4: Harvesting and Washing

Once the salt crystals have formed, they are harvested and transported to a washing facility where they are cleaned and washed to remove any impurities. The washed salt is then transported to a storage facility where it is kept until it is sold to customers.

The Advantages of Industrial Salt Production

Industrial salt production has several advantages over traditional salt production methods. These include:

  • Increased production capacity
  • Higher purity levels
  • Consistency in quality and quantity
  • Greater efficiency and cost-effectiveness

The Future of Salt Production in NTT

Salt production in NTT is a vital industry that provides employment and contributes to the local economy. With the increasing demand for salt, there is a need for NTT to invest in modern, efficient, and sustainable salt production methods.

The government has initiated several programs to support the salt industry in NTT, including providing loans and technical assistance to salt producers. The private sector has also shown interest in investing in the industry, which bodes well for the future.


The industrial production of salt in NTT has come a long way from the traditional methods used in the past. With the increasing demand for salt, there is a need for modern, sustainable, and efficient production methods that can produce high-quality salt at a reasonable cost.

The future of salt production in NTT looks promising, and with the right investments and support, it is expected to continue to grow and contribute to the local economy.
