Abstrak
Penelitian ini bertujuan untuk mengetahui hypertrophy otot pada latihan beban menggunakan metode latihan
compound set pada member fitness center GMC (Gajah Mada Medical Center). Jenis penelitian adalah eksperimen
dengan desain “TheOne Group Pretest-Postest Design”. Populasi dalam penelitian ini adalah member fitness GMC
(Gajah Mada Medical Center) yang berjumlah 32 orang. Teknik sampling menggunakan purposive sampling, dengan
kriteria tertentu. Berdasarkan kriteria yang telah ditentukan yang memenuhi berjumlah 11 orang. Instrumen yang
digunakan untuk mengukur otot lengan, dada, perut, dan otot kaki yaitu pita ukur (medline) dengan satuan
centimeter.Analisis data menggunakan uji t dengan taraf signifikansi 5 %. Sebelumnya dilakukan uji prasyarat yaitu
menggunakan uji normalitas menggunakan Kolmogorov-Smirnov dan uji homogenitas menggunakan uji anava test.
Hasil penelitian menunjukkan bahwa: (1) Ada peningkatan massa otot pada latihan menggunakan metode compound
setterhadap hypertrophy otot dada pada member fitness center GMC (Gajah Mada Medical Center), dengan nilai t
hitung9,238 >ttabel (df10;0,05) 2,228, dan nilai signifikansi p 0,000< 0,05, dan peningkatan massa otot dada sebesar 1,66%,
sehingga Ha diterima. (2) Ada peningkatan massa otot pada latihan menggunakan metode compound set terhadap
hypertrophy otot lengan pada member fitness center GMC (Gajah Mada Medical Center), dengan nilai t hitung6,708
>ttabel (df10;0,05) 2,228, dan nilai signifikansi p 0,000< 0,05, dan peningkatan massa otot lengan sebesar 4,29 %, sehingga
Ha diterima.

Abstract
This research intends to figure out the muscle hypertrophy in weight training using compound set exercise
method of members of GMC (Gajah Mada Medical Center) fitness center. This research was experimental with "The
One Group Pretest-Posttest Design". The population in this research were the members of GMC (Gajah Mada
Medical Center) fitness of 32 members. The sampling technique used purposive sampling with specific criteria. Based
on predetermined criteria, the members that met the criteria were 11 members. The instrument used to measure the
arm, chest, abdomen, and leg muscles was by measuring tape (Medline) with centimetre unit. The data analysis was
using the t test with significance level 5%. The previous prerequisite test was performed earlier by using normality of
the Kolmogorov-Smirnov and homogeneity test using Anova test. The research results show that: (1) there is an
increase in muscle mass using compound set exercise methods on chest muscles hypertrophy of the members of GMC
(Gajah Mada Medical Center) fitness center, with the value of t count 9,238> t table (df10; 0.05) 2.228, and
significance value p 0,000 <0.05, and increase of chest muscle mass of 1.66%, so that Ha is accepted. (2) There is an
increase in muscle mass in using compound set exercise method on arm muscles hypertrophy of the members of GMC
(Gajah Mada Medical Center) fitness center, with the value of t count 6,708> table (df10; 0.05) 2.228, and the
significance value p 0,000 < 0.05, and the increase of arm muscle mass of 4.29%, so that Ha is accepted.
