Penelitian ini menggunakan metode penelitian hukum normatif yaitu mengacu kepada norma hukum yang terdapat dalam peraturan perundangundangan dan keputusan pengadilan. Penelitian kepustakaan tersebut dilanjutkan dengan penelitian lapangan melalui wawancara dan peninjauan ke dua desa di Lebak, Banten. Yang menjadi permasalahan dalam disertasi ini adalah apakah perjanjian-perjanjian dalam Pola Perusahaan Inti Rakyat Perkebunan di Lebak, Banten adil bagi petani peserta? Apakah Pola Perusahaan Inti Rakyat Perkebunan dapat membawa kesejahteraan yang kontinu kepada petani peserta di Lebak, Banten? Faktor-faktor apakah yang menyebabkan Pola Perusahaan Inti Rakyat Perkebunan di Lebak, Banten akhirnya tidak berhasil? Usaha-usaha apakah yang perlu dilakukan agar Pola Perusahaan Inti Rakyat Perkebunan membawa keuntungan baik untuk perusahaan inti maupun petani peserta di Lebak, Banten? PIR Perkebunan dilaksanakan untuk membangun petani perkebunan yang sejahtera dan mandiri melalui peningkatan pendapatan dan taraf hidup. Untuk mencapai tujuan tersebut dilakukan melalui mekanisme yang telah diatur dalam peraturan perundang-undangan dan perjanjian. Pola PIR Perkebunan dalam pelaksanaannya mengalami hambatan-hambatan atau kesulitan-kesulitan. Di samping ada PIR Perkebunan yang berhasil, tetapi ada pula yang mengalami kegagalan. Hasil penelitian menyimpulkan bahwa perjanjian dalam Pola PIR Perkebunan yaitu perjanjian pembelian-pembayaran hasil panen dan kredit petani peserta dibuat dalam bentuk standar dengan tujuan untuk memperhatikan asas keseimbangan, tetapi dalam pelaksanaannya tidak selalu tercapai. Perjanjian mengenai pengelolaan kebun dan kredit petani peserta dibuat dalam bentuk perjanjian standar dan isinya belum sepenuhnya adil bagi petani peserta. Sementara perjanjian kredit dibuat dalam bentuk standar, tetapi dalam perjanjian tidak ditemukan unsur-unsur yang memberatkan petani peserta. Selanjutnya Perjanjian Produksi dan Jual Beli buah kelapa sawit semula dibuat untuk memberikan keuntungan bagi perusahaan inti dan petani peserta, tetapi perjanjian tersebut belum sepenuhnya adil bagi petani peserta. PIR Perkebunan akhirnya tidak dapat membawa kesejahteraan yang kontinu kepada petani peserta di Lebak yang ditunjukkan dengan rendahnya tingkat pendapatan petani peserta dan beberapa mengalihkan tanah perkebunan. Pola PIR Perkebunan yang mempunyai tujuan mulia ternyata gagal membawa kesejahteraan kepada petani peserta di Lebak karena tidak berjalannya mekanisme dalam Pola PIR Perkebunan. Usahausaha yang perlu dilakukan agar PIR Perkebunan dapat membawa keuntungan bagi perusahaan inti dan petani peserta di Lebak diantaranya harus dilakukan perbaikan tugas dan peran perusahaan inti serta petani peserta, kelembagaan petani peserta harus dibentuk dan diperkuat, serta kemitraan antara perusahaan inti dan petani peserta harus diperbaiki.
