Why one system

Stop reconciling four versions of the same month

Most mines already collect the data they need. Production, maintenance, finance and HR each keep their own copy, and the copies rarely agree. Terrasakti keeps one copy for everyone.

Every site

In one system

Coal, nickel, bauxite, manganese, gold, tin and quarry sites run side by side. Each site keeps its own units, and production from different commodities is never added together.

Shift

Level of every record

Every tonne, litre, hour and work order is tied to a shift, a crew and a machine. A shortfall can be traced to where it happened.

One

Version of the figures

The site, the GM and the owner read the same numbers. There are no exports to pass around and nothing to reconcile by hand.

Live

Shift reporting

Dashboards read the records crews enter. The shift report is ready before the next shift starts, not at month end.

These figures describe the platform itself, not customer results. You can check each one in a demo account.

The platform

Built the way a mine is run

Four workspaces cover the pit, the plant, the business and the licences behind them. Each one works on its own. All four read the same records.

Production hub

See tonnes against plan before shift handover

Ore, overburden and stripping ratio are compared with the plan through the day. A shortfall shows up on the shift it happens, not at the monthly review.

  • Plan against actualThe monthly plan sits beside actual tonnes and BCM, by pit and bench.
  • Trace every tonne to its blastDrill holes, blast results and fragmentation are linked to the same block.
  • Every lost hour explainedRainfall and site conditions sit on the production chart. Each lost hour has a recorded cause.

Modules

16 modules. One database.

Each module has its own forms, reports and permissions. None of them keeps a separate copy of your data. Start with one and add the rest in any order.

How it works

From the bench to the owner’s report

Turning site data into a decision used to take a month. With every team on the same records, it happens within the shift.

  1. 01

    Record it where it happens

    Supervisors, fuelmen and planners enter the work on site. The people who did the work are the ones who record it.

    Shift records
  2. 02

    Check it on entry

    Each entry is checked against its work order, machine and shift. Errors are caught when they are made, not at month end.

    Checked records
  3. 03

    Report as you go

    Output, cost and throughput update as records come in. The shift report is ready before handover.

    Shift report
  4. 04

    Act within the shift

    KPI alerts reach the people responsible by email. The problem is dealt with on the same shift.

    Assigned actions
Advanced analytics

Catch losses before the month closes

Every entry from site is kept in one place and is ready for forecasts and anomaly checks. There are no exports to clean and no side spreadsheets to keep.

Where it pays off

Money leaks where work changes hands

These are six places where mines lose money without noticing. Each card shows how Terrasakti closes the gap.

Fuel

Diesel is issued on paper and reconciled once a month. Any shortfall is written off.

Every delivery, restock and refuel is linked to a machine, an operator and a work order. The fuel balance can be closed every day.

Every shiftfuel variance checked
Maintenance

A planned service stalls because the part was never in the warehouse.

Maintenance plans read current stock and open purchase orders. A missing part is flagged when the job is scheduled.

At schedulingparts availability checked
Drill & blast

Blasts are judged by eye. Poor fragmentation quietly slows the excavators and the crusher.

Each blast is measured against its design. Hole records, recovery and fragmentation are kept together.

Every blastmeasured against its design
Commercial

Sold tonnes and produced tonnes sit in different spreadsheets and never quite agree.

Sales are checked against production and processing tonnes in the same system before anything is reported.

One recordfrom production to invoice
Shipping

A barge is priced in a spreadsheet from the index, the survey and the CoA. The royalty is worked out again somewhere else.

The shipment carries its draft survey, its CoA and its price formula. Price, exchange rate and royalty are worked out together and fixed when it is approved.

One recordfrom survey to royalty
Multi-site

A group runs a coal pit and a quarry. Their tonnes end up added together in one report that means nothing.

Each licence is a site with its own commodity and units. Head office sees the sites side by side, and a site login sees only its own.

Per licencenever summed across commodities
People

Attendance is copied by hand from site sheets into payroll. The errors appear on payday.

Rosters, attendance, pay rates and payroll are linked. Each step is checked before the next one starts.

No re-entryfrom site to payslip
Reporting

The monthly report pack takes a week to build and is out of date when it arrives.

Reports read straight from current records. Report packs are emailed on a schedule, in PDF and Excel.

Always currentnothing to rebuild
Rollout

Go live without stopping the site

There is no twelve-month migration. Each phase is useful on its own. Nothing goes live until the crews are ready to use it.

  1. Foundation

    Map the operation

    We set up your sites first. That means each licence and what it mines, pits and benches, the equipment register, crews and cost centres. From day one, every screen uses your site’s own names and units.

    • Licences & site profiles
    • Asset & site register
    • Role matrix
  2. First module

    Go live with one module

    This is usually production or fuel. Losses there are largest, and the gain is easiest to see.

    • Shift entry live
    • Daily reconciliation
    • Supervisor training
  3. Integration

    Connect the other departments

    Plant, logistics, HR and sales join one at a time on the same register. Each handover between teams is covered in turn.

    • Maintenance & stock linked
    • Roster to payroll linked
    • Sales reconciliation
  4. Analytics

    Turn on analytics

    Once you have a reliable operating history, forecasts and anomaly alerts have real data to work with.

    • Forecasts
    • Anomaly alerts
    • Executive reporting

Built around the mine cycle

Terrasakti is not a general ERP adapted for mining. Its records start with the licence, the block, the shift and the work order, for open pit, underground, alluvial and quarry sites.

Rolls out module by module

Start where the loss is largest. Each module works on its own and is worth more as others go live.

Designed for site crews

A supervisor can finish the shift forms on a tablet. No accounting training is needed.

Works with your existing systems

Exports and an API let your finance, telemetry and reporting teams keep the tools they already use.

Security

Every figure has a name and a time on it

Terrasakti has the controls that finance, safety and IT teams expect from business software. Access is set by role, and each company’s data is kept apart.

Role-based access

Permissions are set per module and per action, and a login can be limited to some sites. Approvals are a separate permission, so nobody signs off their own work.

Fraud and risk monitoring

Anomaly checks watch fuel, payroll and stock for the patterns that come before real losses.

A full audit trail

Each record shows who entered it, when, and for which shift. Any figure can be traced to its source.

  • Role-based access control
  • Logins limited by site
  • Input validation
  • Audit trail on every record
  • Encrypted in transit
  • Each company’s data kept separate
  • Least-privilege service accounts

Common questions

What general managers ask before they buy

Straight answers on cost, rollout, connectivity and data.

How much does Terrasakti cost?

We quote each site after a walkthrough. The quote is based on the modules you start with, and you can add others later. Data exports and API access are included at no extra cost.

Do we have to buy every module at once?

No. Each module works on its own and shares the same equipment, site and staff records. Most operations start with production or fuel. They add other modules once the first one has proved its value.

Does it work for our commodity?

Terrasakti covers coal, nickel, bauxite, manganese, gold mining, alluvial tin and quarries. It handles open pit, underground, alluvial and quarry sites, and washing plants. Smelting and gold leaching plants are not covered. When you set up a site you choose what it mines, and its units, moisture basis and grade attributes follow.

We hold several licences. Can each one be run separately?

Yes. Each licence is a site with its own commodity and units. Head office sees every site side by side, and production from different commodities is never added together. A login can be limited to the sites that person works on.

Does it cover RKAB and compliance reporting?

Yes. The RKAB for each licence is compared with actual production and sales month by month. Reclamation, guarantees, environmental monitoring and incidents are recorded on the same licence, and the compliance report pack is built from them.

How long does rollout take?

It depends on the first module and on how ready your site data is. We set up your pits, equipment register and crews first. Then one module goes live, usually production or fuel. In the walkthrough we show you what the first 90 days would look like at your site.

Will it work at a remote site with a weak connection?

Yes. Forms are light and send little data, so a basic satellite link is enough to keep site and head office in step. Refuel sheets entered while the link is down stay on the device. They are sent when the connection returns.

Does it replace our ERP?

No. It works beside your ERP. An ERP is built around accounts. Terrasakti is built around the mine, with its blocks, shifts, equipment and work orders. Operational data lives in Terrasakti and statutory accounting stays in your ERP. Exports and the API move figures between the two.

Who owns our data?

You do. You can export it at any time, and API access is included at no extra cost. Each company’s data is kept separate from every other company’s.

Who can see what?

Access is set by role, for each module and each action. A crew supervisor, a maintenance planner, a payroll officer and a general manager each see only what their role needs. They all read from the same records.

Will supervisors actually use it at the end of a shift?

It was designed for exactly that. Shift forms are short and check entries as they are made. They ask only for what a supervisor already knows. If a field cannot be filled in from the bench, it does not belong on the shift form.

How do you train our people?

Training is part of the rollout. We train supervisors on each module before it goes live. Nothing goes live until the crews are ready to use it.

What language is support in?

Bahasa Indonesia and English. Our team is based in Indonesia, so you can talk to us in the language your site uses.
