N2  - The student?s Ability to solve problems in daily life is considered low. Though the
problem of environmental pollution due to organic waste requires problem solving
ability to critically and creatively. In the world of education, problem-solving skills can
be taught to students through the model of Problem Based Instruction (PBI). This
research purposed to determine the implication of Problem Based Instruction (PBI)
model toward student?s ability in solving of environmental pollution problems. This
research was a Pre Experimental Design using the One Group Pretest-Posttest Design.
The research was done at SMA Negeri 1 Lamongan on January to July at class X with
sample 7 regular classroom. Collected data of the student?s ability to solve problems
using pretest and posttest methods of assessment with average reliability of the
instrument was 0.78, as well as observatory method to observe the feasibility of student
activities. The result of test data were analyzed using the technique of Spearman rank
correlation with ?=5% followed by calculating the determination coefficient, while the
observations data were analyzed by descriptive quantitatively. The results of research
showed that students? ability to formulate the problem, determine the hypothesis and
research variables was less than 20%, however there are positive implication and
significant between implementation of PBI models for students? ability in solving
environmental pollution problems by 98,01%, with value of RS=0,99 (very high) and ZH
(12.69) > Z table (0.96).
