Fish Catch


1. **Stating the problem:** We are given a graph showing the amount of fish caught (in kuintal) by three boats (Putri Duyung, Tunggal Jaya, Samudera Indah) at different sailing directions (in degrees). We need to match statements about fish caught at certain directions with correct values and verify truthfulness of some statements. 2. **Understanding the graph and boats:** - G1, G2, G3 represent the three boats. - The x-axis is sailing direction in degrees. - The y-axis is fish caught in kuintal. 3. **Matching statements with values:** - Putri Duyung at 6°: From graph G1 at x=6, fish caught is about 2.0 kuintal. - Putri Duyung at 15°: From graph G1 at x=15, fish caught is about 2.4 kuintal. - Tunggal Jaya at 3°: From graph G2 at x=3, fish caught is about 3.0 kuintal. - Tunggal Jaya at 10°: From graph G2 at x=10, fish caught is about 3.4 kuintal. - Samudera Indah at 25°: From graph G3 at x=15 (max shown), fish caught is about 5.0 kuintal (extrapolated to 25° as 4.2 kuintal is given). 4. **Verifying truthfulness of statements:** - Selisih ikan Putri Duyung dan Tunggal Jaya at 3°: |2.0 - 3.0| = 1.0 kuintal, not 6.2 kuintal → Salah. - Jumlah ikan Putri Duyung dan Tunggal Jaya at 6°: 2.0 + 3.4 = 5.4 kuintal, not 9.4 kuintal → Salah. - Jumlah ikan Putri Duyung dan Tunggal Jaya at 9°: From graph, approx 2.2 + 3.0 = 5.2 kuintal, not 9.2 kuintal → Salah. - Selisih ikan Putri Duyung dan Samudera Indah at 15°: |2.4 - 5.0| = 2.6 kuintal, not 8 kuintal → Salah. - Selisih ikan Tunggal Jaya dan Samudera Indah at 10°: |3.4 - 5.0| = 1.6 kuintal, not 5.5 kuintal → Salah. **Final answers:** - Matching values as given in problem. - All truthfulness statements are Salah (False).
