Computer Rental for Exams: Minimum CBT Specs for Mass Testing

Summary
Guide to renting computers for exams and mass testing: minimum CBT specs, laptop vs mini PC, a 150-unit cost simulation, and the D-7 deployment timeline.
The safest way to rent computers for exams and mass testing is to follow one minimum-spec baseline: an Intel Core i3 10th generation or newer (or an AMD Ryzen 3 5300U), 8GB of RAM, a 256GB SSD, and a front-facing camera for proctoring — ordered as a package of 100-500 units with the lockdown browser pre-installed, from Rp 50,000/unit/day. That is the standard Arental applies to PPDB school admissions, BNSP certifications, campus semester exams, and CPNS civil-service tests running on the BKN CAT system. This article breaks the specification down by exam type, helps you choose between laptops and desktop PCs, then works the cost out concretely so your committee can submit a budget without guessing.
What Is the Minimum Computer Spec for a CBT Exam?
Most CBT providers in Indonesia today run web-based platforms — the exam portal opens inside a lockdown browser, and questions stream from a central server. For that workload, the reliable specification is lower than committees often assume, but there is a floor you must not go under:
| Component | Safe minimum (web-based CBT) | Intensive proctoring (CPNS BKN, international certification) |
|---|---|---|
| Processor | Intel Core i3 10th gen+ / AMD Ryzen 3 5300U | Intel Core i5 (ThinkPad T490/T14 class) |
| RAM | 8GB | 8-16GB |
| Storage | 256GB SSD | 256GB SSD |
| Display | 14-inch HD/FHD | 14-inch FHD |
| Camera | Front camera for live proctoring | HD camera + stable audio under streaming |
| Battery (for laptops) | Healthy, 6+ hours | Healthy, 6+ hours |
Why does intensive proctoring need the step up? Because video proctoring streams the camera and audio continuously while the exam application runs. On an i3-class processor, that streaming load can throttle the CPU at the exact moment a candidate opens a question — the screen stutters, answers save late, and invigilators panic. For CPNS tests on the BKN CAT system or international certifications, an i5-class unit such as a ThinkPad T490/T14 is the realistic floor.
In the field, the units most often deployed at the base tier are the Lenovo ThinkPad T440/T460/T470, HP EliteBook 840 G3/G5, and Dell Latitude 5480/5490 — business generations proven under exam workloads, not consumer laptops whose behavior varies unit to unit.
The Lockdown Browser: the Part Committees Forget Most Often
Hardware specification is only half the story. Exam computers must be imaged with whatever lockdown browser the committee or provider specifies: Safe Exam Browser for Moodle platforms, the dedicated exam browser from an LSP/BNSP certification body, the BKN CAT system, an assessment provider's application (Pearson VUE or Prometric in their local flavor), or a standalone CBT app from a regional Education Office PPDB committee.
On Arental's CBT exam laptop rental packages, every unit is boot-tested into its lockdown profile before delivery, and the common cheating vectors are disabled at the image level: USB autoplay, user switching, the Task Manager shortcut, and Cortana. If a vendor you are evaluating only talks specs and never mentions lockdown imaging, that is a sign the package has never run a real exam.
Laptops or Desktop PCs for Mass Testing?
Many committees go straight to renting desktop PCs for online tests, when for a temporary venue laptops are actually the safer choice. This is the first decision, it sets your cost structure, and the answer hinges on one variable: how long the computers will stay put at the location.
| Criterion | CBT laptops (daily rental) | 1L mini PC / AIO (monthly rental) |
|---|---|---|
| Pricing scheme | Rp 50,000-120,000/unit/day | From Rp 300,000/unit/month |
| Best for | 1-14 day exams at temporary venues (halls, schools, ballrooms) | Exam/training labs operating for months |
| Power | 6+ hour battery rides out power flickers without a UPS | Needs stable power or a UPS per desk row |
| Network | Wi-Fi or LAN via adapter | Wired RJ-45 Gigabit LAN — most stable for long sessions |
| Per-desk setup | Open, power on, log in | Monitor + VESA-mounted unit, installed by the vendor crew |
| Teardown speed | Collected within hours of the final session | Dismantled on schedule at contract end |
The rough math goes like this: for an exam window of a few days, the CBT laptop package is priced per exam day (Rp 50,000/unit/day at the standard tier, including lockdown imaging, spare units, and the invigilator briefing) — the most practical option, since units arrive, get used, and are collected. For a campus CBT lab running a full semester, the comparison is monthly rates: an entry laptop at Rp 250,000 or a 1-liter mini PC (Lenovo ThinkCentre Tiny M70q/M80q/M90q, HP EliteDesk 800 Mini, or Dell OptiPlex Micro) from Rp 300,000 — a thin gap, with the mini PC winning on a full-size monitor, wired LAN, and units that stay neatly at each lab desk.
For a permanent lab, 1-liter units are VESA-mounted behind the monitor so lab desks stay tidy, or you can switch to uniform All-in-One PCs that need just one unit per desk. Form factors, brands, and the delivery-plus-setup scheme are detailed on the PC and All-in-One rental Jakarta page.
How Much Does Renting Computers for an Exam Cost? A 150-Unit Simulation
Arental's CBT laptop package pricing splits into three tiers by unit generation and proctoring load:
| Tier | Typical volume | Example units | Rental price |
|---|---|---|---|
| Standard | 100-200 units | ThinkPad T440/T460, EliteBook 840 G3, Latitude 5480 | Rp 50,000/unit/day |
| Premium | 100-300 units | ThinkPad T470/T480, EliteBook 840 G5, Latitude 5490 | Rp 50,000/unit/day |
| Heavy Proctoring | 200-500 units | i5-class with HD cameras for video proctoring | Rp 80,000/unit/day |
Now let us plug those numbers into a real scenario: a junior-high PPDB admission test with 150 standard-tier units over a 5-day exam window.
| Component | Calculation | Cost |
|---|---|---|
| Unit rental | 150 units x 5 days x Rp 50,000 | Rp 37,500,000 |
| 4% spare pool (6 units on-site) | Included in the package | Rp 0 |
| Lockdown imaging + per-unit boot test | Included in the package | Rp 0 |
| 60-minute invigilator briefing + per-venue SOP | Included in the package | Rp 0 |
| 5-day total | Rp 37,500,000 |
How to read it for a budget submission: at 3 sessions per day, 150 units serve 450 candidates daily — 2,250 candidate slots over 5 days. Dividing total cost by candidate slots yields roughly Rp 16,700 per candidate per session. That per-candidate figure is usually far easier to get leadership sign-off on than the lump sum, because it compares directly against per-candidate catering or invigilator honorarium costs.
Deployment Timeline: from D-7 to D+1
Mass tests fail not on specification but on logistics that start too late. The proven deployment flow for multi-location packages:
1. D-7 — Site survey. Technicians check power, network, and desk layout at every venue. This is where you discover the school hall has only 4 power outlets for 100 desks. 2. D-3 to D-2 — Per-venue deployment. Units are delivered and handed over to the local committee lead, complete with a serial-number checklist. 3. D-1 — Technical rehearsal. Every unit boots, logs into the exam portal, and runs a short sample question set under invigilator supervision. Problems surfacing here can still be solved; problems surfacing on exam day have no time left. 4. Exam day — Technicians on standby. A problem unit is swapped for an on-site spare in under 15 minutes, without halting other candidates' sessions. 5. D+1 — Collection + handover certificate. Units are collected against the serial-number checklist, then the final BAST handover certificate is signed per venue — the document that keeps asset accountability tidy for your management or auditors.
When Should the Committee Place the Order?
For a 200-unit multi-venue package, the minimum lead time is 10-14 working days before exam day: spec and lockdown confirmation, per-venue site surveys, mass imaging at the Kebon Jeruk warehouse, deployment, then the rehearsal. For PPDB, whose schedule is fixed by the regional Education Office (May-June), the ideal order lands at D-21. An order at D-7 or later can still be accommodated, but as a spec-fixed package without custom lockdown and at rush pricing — so delaying the decision has a price, literally.
The Technical Checklist Before Exam Day
The four most common incident sources at mass tests, and how to close them:
- Power per desk row. Count outlet needs during the site survey, not on exam day. Laptops with healthy 6+ hour batteries give you tolerance when venue power flickers — one reason temporary venues almost always run laptops, not desktops.
- Network. For a stationary lab, wired RJ-45 LAN is more stable than Wi-Fi across long exam sessions; desktop and AIO units generally ship with a built-in Gigabit Ethernet port.
- The 4% spare pool. Arental's CBT package standard is 1 spare unit per 25 active units, ready on-site. Without spares at the venue, one dead unit means one candidate loses their session.
- Unit roll-call per session. Require invigilators to count units at the start and end of each session. With that control in place, the three-year statistics on Arental CBT packages: major damage under 0.3% and lost units under 0.05%.
The same protection pattern applies to large-scale event hardware in general — registration desks, media centers, committee rooms. The event-side discussion is in our guide to laptop rental for events in Jakarta.
Frequently Asked Questions
Can the rented computers run our own internal exam application?
Yes. Units are imaged with whatever application the committee specifies — from Safe Exam Browser, LSP/BNSP browsers, and the BKN CAT system to an HR team's internal assessment app for recruitment. Send the installer or platform name when requesting a quotation so it enters the mass-imaging process rather than being installed manually on site.
What is the minimum number of units we can rent for a test?
There is no rigid minimum. CBT packages typically run at 100-500 units, but corporate recruitment assessments commonly run at 20-80 units per wave, and training labs can start from a dozen or so monthly desktop units.
What happens if a unit fails in the middle of an exam session?
The unit is swapped for an on-site spare in under 15 minutes by the standby technician at the venue. The candidate moves to a spare imaged identically, and other candidates' sessions are not disturbed.
Is this available for venues outside Greater Jakarta?
Yes — multi-location CPNS tests and certifications routinely run at venues outside Greater Jakarta via logistics partners, with 2-4 days of additional lead time compared to Jabodetabek. For distant venues, exam-day support runs remotely with escalation to the nearest technician.
Who bears the cost if a unit is damaged or lost?
The standard clause is transparent: minor damage (scratches, scuffs) is covered by the package insurance at no extra charge; major damage (cracked LCD, motherboard failure) is borne by the committee at the vendor part price list provided before the exam; a lost unit is charged at market value — which is why the per-session unit roll-call matters.
Lock In Units for Your Exam Schedule
Exam dates do not move, so lock in the units first. Send a WhatsApp message to +62 821-4777-2100 with: the exam type (PPDB/certification/CPNS/campus/recruitment), estimated unit count, city and venue, and the exam date.
