composite narrative. Composite Karanganyar co-op narrative with unverified 6-day-to-4-hour close and 78% application figures; not backed by public evidence or guaranteed. Figures are not independently verified and do not guarantee results.
// narrative context
The reported situation
This composite narrative describes a cooperative of roughly 1,800 members operating across three Excel files plus a manual teller ledger. In the scenario, members visit during office hours to check balances while the board reconciles conflicting sources before RAT. The narrative reports a 6-working-day monthly close. No consent reference, supporting artifacts, raw data, or public URL is available in the repository, so the identity, events, and figures cannot be independently verified or read as a real client outcome.
// approach in the narrative
The documented steps
/ step 01
Discovery started from their Excel files, not from a brief
The illustrative approach starts by mapping the files, roles, and one transaction from input to recap. Any unwritten service-charge rule must be decided by the board before the database and scope are agreed. This discovery pattern is explained in [how we work](/cara-kerja); it is not documentation of a verified client project.
/ step 02
The savings module uses co-op terms, not generic accounting terms
In this composite design, simpanan pokok, wajib, and sukarela follow separate rules. Every movement leaves an audit trail, while member phone access is an optional module. Final rules still follow the cooperative's bylaws, board decisions, discovery findings, and written scope.
/ step 03
Loan applications from the member's phone, tiered approval on the board's side
The module scenario allows phone applications, ceiling-based approval, calculations based on agreed rules, and role-based access for the teller, board, and supervisory team. Notifications can be a Custom/Add-on such as [WhatsApp API integration](/layanan/whatsapp-api). This is a solution pattern, not proof of a specific implementation.
/ step 04
A board dashboard, a parallel migration, then handover
The composite blueprint includes a dashboard, report export, staged migration, a parallel Excel run, reconciliation, and training by role. Reporting duties must be checked against the rules in force when a project begins. The technical foundation can use a [custom web app](/layanan/web-app), with details binding only after discovery.
// qualified outcomes
Reported baselines and outcomes
Every figure below is qualified according to the entry's governance status. The evidence notes state the available baseline, period, method, and public-verification limits.
| Metric | Before | After |
|---|---|---|
| Monthly book-close time | 6 working days | 4 hours Reported in the composite narrative as a before-and-after comparison. Supporting artifacts are unavailable, so the figure cannot be independently verified. |
| Loan applications received | Baseline period before the system | +78% Reported in the composite narrative against an equivalent period. Raw baseline, denominator, artifacts, and attribution evidence are unavailable; the percentage is not a forecast. |
| Operational data sources | 3 separate Excel files + a manual teller ledger | 1 database with an audit trail per transaction The composite narrative describes a parallel run until balances matched. Reconciliation logs are unavailable for independent verification. |
| How members check their balance | Come to the office during working hours | Log in from a phone, any time This is an access pattern in a composite narrative, not a survey result or evidence of actual adoption. |
// testimonial narrative
“The book close used to take six days, and for those six days the treasurer was practically unusable for anything else. Now it's finished before lunch. The part that hits hardest isn't even that — members stopped calling to ask about their balance, because they can see it themselves on their phone.”
// takeaway
If operations run across files that copy from one another, measure reconciliation time, correction volume, and access friction before setting scope. This composite narrative reports a 78% rise in applications, but no consent reference, supporting artifacts, raw data, or public URL is available. The figure cannot be independently verified, is not a published client result, and does not predict another project. The module pattern appears in [co-op systems](/sistem/koperasi), with cost ranges on [pricing](/harga).

How long does the work take before it's genuinely in use?
Our co-op has used Excel for years. Can the data be moved?
A lot of our members aren't used to apps. Isn't this pointless?
What about member data security and ownership of the system?
