For owners and finance
The analytics run on figures a finance team can use.
Production, cost, and sales are recorded as the work happens. Ask a question and the answer comes from those records, with the source under it. The forecast to month end is the method that best matched this mine's recent history.
Any
Commodity, in its own units
Coal, nickel, gold, tin, and quarry aggregate are ready as starting points. A site then sets its own method, unit, selling basis, and grades. A tonne of one commodity is never added to a tonne of another.
Daily
Updated as the work is recorded
Every tonne, litre of fuel, and maintenance job is stored with the date, the team, and the machine. If a result is short of plan, you can see where it happened.
1
Set of figures for the company
The site manager, the finance team, and the owner open the same production, cost, and sales figures. The monthly report is drawn from those records.
0
Days spent rebuilding the operating report
The report updates as the site enters the work. Finance does not wait weeks for someone to assemble it from separate files.
These describe how the product works. You can check each one in a demo account.
Commodities
A starting point for the commodity, not a limit.
Coal, nickel, bauxite, manganese, gold, tin, and quarry aggregate are ready to begin from. A site then sets how it mines, the unit it reports in, the basis it sells on, and the grades it assays. Another commodity is that same setup. Figures from different commodities stay separate.

Several licences, one group view
Head office sees every site side by side, each in its own units. A site login sees only its own. Figures from different commodities are not added into one total.
The operation
The four workspaces share one set of records.
The pit, the plant, the commercial office, and the licence. Each workspace can run on its own. All of them read the same equipment, the same sites, and the same people.
Production
Spot production shortfalls while there is still time in the shift to respond.
Compare ore, overburden, and stripping ratio with the plan as the day unfolds. When production falls behind, your team can see the gap early enough to investigate and respond.
- Plan beside actualThe monthly plan sits next to actual tonnes and BCM, by pit and by bench.
- Tonnes tied to the blastDrill holes, blast results, and fragmentation stay on the same block.
- A reason for each lost hourRain and site conditions sit on the production chart, so a lost hour is explained when it is recorded.

Modules
All 16 modules read the same records.
Each module has its own forms, reports, and permissions. Equipment, sites, and people are stored once. Start with the module you need, and add the others once that one is in daily use.
How it works
The work is recorded and reported inside the shift.
Supervisors, fuelmen, and planners record the work where it happens. Each entry is checked as it arrives, and the shift report is written before the crew hands over.
- 01
Record work on site
Supervisors, fuel teams, and planners record work where it happens, helping reduce the gap between what took place on site and what appears in the report.
Shift records - 02
Catch data issues early
Entries are checked against the relevant machine, work order, and shift as they are recorded, so teams can catch mistakes before they flow into month-end reporting.
Checked records - 03
See progress during the shift
As records come in, production, cost, and throughput views update. By handover, the shift report is ready to review instead of being rebuilt from scratch.
Shift report - 04
Give teams time to respond
When a KPI crosses its configured threshold, the responsible person is alerted while there may still be time to investigate and act.

Ask Terra · AI Assistant
Ask it the way you would ask a colleague.
Terra looks the answer up in your company's records, replies in Bahasa Indonesia or English, and shows the source of every figure.
Questions you can ask
- How much overburden did we move this month compared to plan?
- Which units had the most breakdown hours last week?
- What is our fuel per BCM this month, by pit?
Ask Terra is an add-on, switched on for each company. We can include it in the walkthrough.

Ask about production, fleet, fuel, sales…
Ask Terra only reads your data. Check important figures on the linked pages.
Every figure comes from a lookup
Terra does not estimate, and it does not fill a gap with a guess. Each number comes from a query on your data, and the sources sit under the answer.
It sees only what you can see
It runs under your login: your modules, your sites, and your company. A screen you cannot open is a screen Terra cannot read.
It only reads
Terra cannot create, change, approve, or delete a record. If you ask it to, it points you to the screen in the app where that is done.
A blank stays a blank
If nobody entered a value, Terra says it was not recorded. It will not present an empty field as a zero.
Bahasa Indonesia or English
Ask in either language. Mining terms stay as your sites use them: BCM, ROM, overburden, PA, and UA.
Personal records stay out
Payroll, bank, medical, and family records are outside its reach. That is how it is built, and it is not a setting someone can switch off.
Advanced Analytics
See the variance before the month closes.
Forecasts and variance checks run on the records already in the system. The figures stay where the crews entered them.

KPI alerts

Handovers
The figure usually goes missing at the handover.
Fuel, parts, blasts, sales, shipments, licences, payroll, and the monthly pack. These are the points where a number gets copied, delayed, or lost.
Fuel
Diesel goes out on paper and is reconciled once a month. By then, the missing litres have been written off.
Every delivery, tank transfer, and refuel is tied to a machine, an operator, and a work order. The fuel balance closes every day.
Each shiftthe fuel variance is checked
Maintenance
A planned service stops on the day, because the part was never in the warehouse.
Maintenance plans read current stock and open purchase orders, so a missing part is flagged when the job is scheduled.
At schedulingparts are checked against stock
Drill & Blast
The blast is judged by eye. Poor fragmentation then slows the excavators, and nobody can say which pattern caused it.
Each blast is held against its design. Hole records, recovery, and fragmentation stay together.
Each blastcompared with its design
Commercial
Sold tonnes live in one spreadsheet and produced tonnes in another, and the two never quite agree.
Sales are checked against production and processing tonnes before a figure is reported.
Matchedsold tonnes against produced tonnes
Shipping
The barge is priced in a spreadsheet from the index, the survey, and the CoA, and the royalty is calculated again somewhere else.
The shipment carries its draft survey, its CoA, and its price formula. Price, exchange rate, and royalty are calculated together and locked when the shipment is approved.

Several sites
The group runs a coal pit and a quarry, and someone adds the tonnes into a single number that means nothing.
Each licence is a site, with its own commodity and its own units. Head office sees them side by side. A site login sees only its own.

People
Attendance is copied by hand from the site sheets into payroll, and the mistakes appear on payday.
Rosters, attendance, pay rates, and payroll are linked. Each step is checked before the next one starts.

Reporting
The monthly pack takes a week to assemble, and it is already out of date on the day it arrives.
Reports read the current records, and the packs go out on a schedule as PDF and Excel.

Rollout
Bring one module live, then the next.
Each phase is useful on its own. A module goes live when the crews are ready to use it, and the pit keeps working throughout.
Foundation
Set the operation up
We set the sites up first: each licence and what it mines, the pits and benches, the equipment register, and the crews and departments. From the first day, every screen uses your names and your units.
- Licences and site profiles
- Asset and site register
- Role matrix
First module
Go live with one module
Most sites begin with production or fuel, where the loss is easiest to see and the result shows up quickly.
- Shift entry live
- Daily reconciliation
- Supervisor training
The next departments
Join the other departments
Plant, logistics, human resources, and sales join one at a time, on the same register, so each handover closes before the next one opens.
- Maintenance linked to stock
- Roster linked to payroll
- Sales reconciliation

Built around real mining workflows
Operational records are tied to the licence, block, shift, and work order, giving teams the context they need to trace a number back to the work behind it.
Start small, expand when ready
Start with the area causing the biggest operational headache. Use that module on its own, then connect more departments when your team is ready.
Forms designed for the field
Field forms are designed to be practical on a tablet and focus on information supervisors can reasonably enter during the shift.
Works alongside your existing systems
Keep the finance and reporting tools your business already relies on. Export Terrasakti data when you need to use it elsewhere.
Security
Every figure has a name and a time on it.
Access is set by role. Each company's data is stored apart from the others. Every record shows who entered it, and when.
Access by role
Permissions are set per module and per action, and a login can be limited to certain sites. Approval is its own permission, so a person cannot sign off their own work.
Variance checks
Measured fuel, deliveries, stock counts, and surveys are compared with the records. The widest gaps are listed first.
An audit trail on every record
Every record shows who entered it, when, and for which shift. A figure can be followed back to the entry it came from.

Common questions
Answers to the questions we hear most.
Price, rollout, a weak connection from site, Ask Terra, and who can see the data.
How much does Terrasakti cost?
Pricing is tailored to each site and the modules you need. We start with a walkthrough, agree on a practical first step, and leave room to add more modules as your operation is ready. Data exports are included.
Do we have to take every module at once?
No. You can start with one module, such as production or fuel, without committing to the whole platform. Modules share the same site, equipment, and staff records, so you can expand step by step as your team gets comfortable.
Does it cover our commodity?
A site is set up for what it mines: the method, the unit it reports in, the basis it sells on, and the grades it assays. Coal, nickel, bauxite, manganese, gold, tin, and quarry aggregate are ready as starting points, on open-pit, underground, alluvial, and quarry operations, including washing plants. The setup can be changed. Smelting and gold leaching are not part of the product.
We hold several licences. Can each one run on its own?
Yes. Each licence is a site, with its own commodity and its own units. Head office sees every site side by side. Tonnes of different commodities are not added together, and a login can be limited to the sites that person works on.
What is Ask Terra, and what can it see?
Ask Terra is an assistant inside the app. You ask a question in Bahasa Indonesia or English, and it answers from your company's own records, with the sources listed. It runs under your login, so it sees only the modules and sites you can already open. Payroll, bank, medical, and family data are outside its reach.
Can Ask Terra change our data?
No. It only reads. It cannot create, edit, approve, or delete a record, and every figure comes from a lookup on your data. Ask Terra is an add-on, switched on per company. We can show it during the walkthrough.
Does it cover RKAB and compliance reporting?
Yes. Each licence's RKAB is compared with actual production and sales, month by month. Reclamation, guarantees, environmental monitoring, and incidents sit on the same licence, and the compliance pack is built from them.
How long does a rollout take?
The timeline depends on which module you start with and how ready your site data is. We first map your sites, equipment, and crews, then focus on getting one module into daily use. During the walkthrough, we can outline a realistic first-90-day plan for your operation.
Will it work on a remote site with a weak connection?
Yes. The forms are light, so a basic satellite link is enough to keep the site and head office in step. Refuel sheets entered offline stay on the device and send when the link returns.
Does it replace our ERP?
Terrasakti is designed to work alongside your ERP, not replace it. Your ERP can continue handling accounting, while Terrasakti connects the day-to-day details of blocks, shifts, equipment, and work orders. Exports help move the relevant figures between systems.
Who owns our data?
You do. You can export it at any time. Each company's data is stored apart from every other company's.
Who can see what?
Access is set by role, per module and per action. A supervisor, a planner, a payroll officer, and a general manager each see what their role needs, from the same records.
Will supervisors use it at the end of a shift?
The shift forms were written for that moment. They are short, they check entries as they are made, and they ask only for what a supervisor already knows. A field that cannot be filled from the bench does not belong on the form.
How do you train our people?
Training is part of the rollout. We train the supervisors on a module before it goes live, and the module stays off until the crews are ready.
Which languages do you support?
Bahasa Indonesia and English. The team is based in Indonesia, so you can speak with us in the language the site uses.
