Research is conducted through three levels, namely (1) the level of preparation, which includes the collection of references related to the research, making permits, then conducting the same agreement of coaches related to the time of research implementation (2) Implementation rate, which includes determining the sample of the study subject, then giving the treatment to know the effect of the implemented methods and (3) The level of data analysis, the results described by researchers in the report are influence. Training methods Guided Discovery, Series Of Play methods, servicing. This research Model quasi experimentation. The population here is the player of the women's Bolavoli district of Rokan Hulu which amounted to 68 people, while the samples were selected using the purposive sampling technique so that the sample amounted to 30 daughters. Instrument test serviceability using Bolavoli service tests. For test conducted preliminary tests first, before giving the treatment Guided Discovery method, Series Of Play method, then the final test as the final data Of research after the treatment is implemented and data analyzed using Test-T. Data analysis results show that: 1) there is an influence of Guided Discovery Style method of service capability with GIS value. (2-tailled) 0.000 < 0.05.3) The series of play method is more effective in contributing to increased serviceability than the guided Discovery style method. Because of the influence given the series of Play Method (1.8) > method Guided discovery Style (1.34) on the mean result from to the two methods. Abstrak Penelitian ini dilakukan melalui tiga tingkatan, yaitu (1) Tingkat Persiapan, yang meliputi pengumpulan referensi terkait dengan penelitian, membuat perizinan, kemudian melakukan perjanjian sama pelatih terkait dengan waktu pelaksanaan penelitian (2) Tingkat Pelaksanaan, yang meliputi menentukan sampel subjek penelitian, kemudian memberikan perlakuan agar mengetahui pengaruh metode yang dilaksanakan dan (3) Tingkat analisis data, hasil yang di deskripsikan peneliti dalam laporan adalah pengaruh.

Hasil analisis data menunjukan bahwa: 1) Terdapat pengaruh Metode Guided Discovery Style terhadap kemampuan Servis dengan nilai sig. (2-tailled) 0,000 < 0,05. 2) Terdapat pengaruh Metode series of play terhadap kemampuan servis dengan nilai sig. (2-tailled) 0,000 < 0,05. 3) Metode series of play lebih efektif dalam memberikan pengaruh terhadap peningkatan kemampuan servis dibanding dengan metode guided discovery style. Karena pengaruh yang diberikan metode series of play (1,8)> Metode guided discovery style (1,34) pada hasil mean dari ke dua metode.
