Operating budgets for coal mining contractors, step by step.
SEKALA walks a mine planner through a full-year operating budget for one project in the same order the work runs on site: project basis and weather first, then fleet and productivity, owning before operating cost, cost per activity, and finally revenue and profit. Every figure recalculates the moment an input changes.
Dozens of Excel sheets pointing at each other, with formulas only their author understands. Change one assumption — the fuel price, rain hours, the haul distance — and everything has to be recalculated from the start.
One workflow that recalculates every figure as inputs change, where every result can be traced back to its formula and every question about next year can be answered as a scenario.
Seven phases, in the order the site works
-
01
Project basis
Project and contract, calendar and weather: exchange rate, fuel price, twelve months of production targets, working days and rain hours.
-
02
Production
Fleet selection, loader and hauler productivity with fleet matching, and the production plan with its support work.
-
03
Equipment cost
Owning cost — depreciation, interest, insurance — and operating cost: fuel, lubricants, tyres, repairs, operators and rental rates.
-
04
Activity cost
Cost and fuel per bcm or ton for each activity, plus support and fixed costs outside the fleet.
-
05
Financials
Revenue from contract rates, gross profit, and twelve months of profit and loss.
-
06
Approval
The site budget is reviewed by the project manager and then head office before it becomes the master budget.
-
07
Control
Actuals against budget, with a waterfall that breaks the variance into availability, utilisation, productivity and unit-count effects.
After the budget is built
What-If Studio
A finished budget is where the questions start. What if next year is wetter? If fuel rises 15%? Set up to twelve levers, from rain hours to dump-truck availability, and every annual KPI is compared with the base budget.
Ask it like a colleague
Type the question in plain language. The answer comes back with the chart and table it needs.
The AI does not calculate
Every cost, KPI and chart value comes from SEKALA’s budget engine, tested against the reference workbook. The AI only chooses which simulation to run and what to show.
No black-box numbers
Every result has a “show the calculation” button, so any figure can be traced back to its formula.
Rupiah first
Everything is in Rupiah; equipment priced in US dollars converts at a monthly rate you can change at any time.
A head start
Equipment and rainfall data is pre-filled as a starting point. Begin from training sample data or from an empty budget.
Private VPS or on-premise, on infrastructure you own. Not offered as SaaS.
Questions
Who fills in which part?
Each phase belongs to a role — Engineering, Plant, Admin, Finance — and user roles decide who may change what.
Does the AI produce the numbers?
No. Every number comes from the budget engine. The AI only picks which simulation to run and how to present the result.
What currency does it use?
Rupiah. Prices in US dollars are converted at a monthly exchange rate you set.
Can we try it without our own data?
Yes. You can start from the training sample data instead of an empty budget.
Is SEKALA offered as SaaS?
No. It is deployed on a private VPS or on your own servers, so your cost structure stays inside your company.
