[Kajian] FAMA Green Mustard Price 2026: Three Readings, Rising Again

Welcome to case file #2 of the [Kajian] series — betulkex’s dated observation format, not advice. The first file ([[Kajian] used DDR4]) followed one seller’s RAM kit; this second file changes the object’s species: one commodity row in a government price report, read multiple times on multiple dates.

What is the study object, and why does it qualify?

The object: the SAWI HIJAU TANAH TINGGI row in FAMA’s Daily Price Guideline — the national average RM/kg across wholesale and public markets. It qualifies as the second object for two reasons: the row has THREE dated readings already in our fact registry (27/9/2026, 29/9/2026 and 1/10/2026) ^{[source] [source] [source]}, and mustard is the most-asked short-cycle commodity — the DOA guide states harvest as early as 28-30 days after sowing ^[source], so supply is always moving. One row, three lenses — enough for a file, not yet enough for a trend.

What counts as one reading in our protocol?

The series protocol (named so others can check it):

• One reading = one value of a named-class commodity row, from FAMA’s Daily Price Guideline (harga-pasaran-terkini Power BI), captured with its reading date and its status as a national average.
• The object = the class row, NOT premises, NOT a state, NOT another vegetable class.
• Who observes: our observation lane; readings are quoted from the fact registry, not from memory.
• Built-in limit: the daily guideline carries exactly ONE mustard row ^[source]; anything outside that row is not this file’s object.

How did the mustard price move across the three readings?

All three readings read the same row, same class, same unit (RM/kg, national average). The 27/9-to-1/10 gap — the two dates between (28/9, 30/9) have no readings in this file.

How big are the five-sen (and four-sen) spreads?

The math is shown, not asserted, for both steps: RM5.44 − RM5.39 = RM0.05; (RM5.44 − RM5.39) ÷ RM5.39 ≈ +0.9% in two days ^{[source] [source]} — then RM5.48 − RM5.44 = RM0.04; (RM5.48 − RM5.44) ÷ RM5.44 ≈ +0.7% ^{[source] [source]}. Net across 27/9→1/10: RM5.48 − RM5.39 = +RM0.09 (~+1.7%) in four days — the only row in this series moving the same direction across both steps. For level context: the Cameron farm-gate market story records a monsoon band of RM1.00-3.50/kg — a seasonal farm-level story class, far below the wholesale guideline level, and NOT directly comparable with sen-level spreads on a national average ^{[source] [source]}. Three levels (farm, wholesale guideline, retail premises) are three worlds; this file holds only one.

What does this study NOT prove?

This series’ mandatory section — written before conclusions, not as a footnote:

1. Not a trend — three points do not set direction; two same-direction steps (RM5.44 − RM5.39 = +RM0.05 ≈ +0.9%, then RM5.48 − RM5.44 = +RM0.04 ≈ +0.7% — formula-counted) ^{[source] [source] [source]} do not predict next week and do not exclude a bend back.
2. Not premises prices — the national average hides state and market scatter; Supplier A’s quotation today can legitimately sit above or below RM5.48 ^[source].
3. Not other classes — white mustard, pakcoy, caisim have no row; transferring the green figure to them is class corruption ^[source].
4. Not a FAMA purchase price — the guideline’s printed disclaimer: general wholesale/public-market guideline prices, not prices FAMA buys at ^[source].
5. Not a season — three late-September/early-October readings do not capture the monsoon cycle; the monsoon band remains a separate story class ^[source].

Why doesn’t the lowland class enter this file?

Object discipline: the daily guideline row we read is the TANAH TINGGI class ^[source]. FAMA’s 02-10-2026 daily infographic records a 23% rise for SAWI HIJAU TANAH RENDAH ^[source] — a different class, a different source, and that row is not yet in our fact registry, so it is recorded as an evidence slot awaiting admission (see the slot comment on-page), not as a reading of this file. When the lowland class row earns two readings of its own, it qualifies for its own file — not for mixing into this one.

What is next in the series — which object?

The series’ third object was cut simultaneously with this file: Kajian terung FAMA price — the TERUNG PANJANG/PEPARU (TANAH RENDAH) row with two dated readings 27/9 and 29/9, with the spread direction opposite (down, not up). Further object nominations are welcome via WhatsApp below; series entry criteria: a named class row, two dated readings obtainable and tied to the fact registry, no private business information lifted.
