improve the writing achievement of class VIII students at SMP Bala Keselamatan
Kalawara. This research used a quasi-experimental design by applying
nonequivalent control group design. The population was class VIII students at
SMP Bala Keselamatan Kalawara, consisting 37 students from two classes. The
sample was class A as the experimental group and class B as the control group.
Sample selection was carried out using saturated sampling. Tests were used to
collect data consisting of pre-test and post-test. The tests result show that the
average pre-test score obtained by the experimental group is 43.86, while the pretest score obtained by the control group is 46.91. Then, the average post-test score
for the experimental group is 69.00, while the control group is 54.94; the tcounted value (5.52) was higher than t-table value (1.690), which means that the
hypothesis was accepted. The T-test determine the significance and relevance
between two groups of unpaired samples. Based on the research result, the
researcher concludes that the use of clustering technique can improve students’
writing achievement in descriptive text of the eighth grade students of SMP Bala
