Lembar Kegiatan Siswa (LKS) adalah lembaran-lembaran berisi tugas yang harus dikerjakan oleh siswa. Lembar Kegiatan Siswa berbasis Problem Based Learning (PBL) dipilih untuk menjawab tuntutan kurikulum 2013 yang mengharuskan siswa berperan aktif dalam proses pembelajaran. Penelitian ini bertujuan untuk menganalisis proses pengembangan LKS berbasis model pembelajaran problem based learning (PBL) pada kompetensi dasar APBN dan APBD dalam pembangunan ekonomi, menganalisis kelayakan LKS berbasis model pembelajaran problem based learning (PBL) pada kompetensi dasar APBN dan APBD dalam pembangunan ekonomi, serta menganalisis respon siswa kelas XI  SMA Negeri 1 Arosbaya Bangkalan terhadap pengembangan LKS berbasis model pembelajaran problem based learning (PBL) pada kompetensi dasar APBN dan APBD dalam pembangunan ekonomi.

Jenis penelitian yang dilakukan adalah penelitian dan pengembangan (R&D) dengan model 4-D dengan empat tahapan didalamnya. Tahapan tersebut meliputi define (pendefinisian), design (perancangan), develop (pengembangan), dan disseminate (penyebaran). Namun, tahap penyebaran tidak dilakukan. Hasil pengembangan LKS diuji kelayakannya oleh ahli materi, ahli pembelajaran, ahli bahasa, dan ahli grafis. Kemudian, LKS di ujicobakan kepada 20 orang siswa kelas XI SMA Negeri 1 Arosbaya yang selanjutnya setiap siswa memberikan penilaian terhadap LKS yang dikembangkan. Instrumen yang digunakan adalah lembar validasi LKS dan lembar angket respon siswa.

Hasil yang didapat dari penelitian berupa, 1) pengembangan Lembar Kegiatan Siswa berbasis model pembelajaran problem based learning (PBL) pada kompetensi dasar APBN dan APBD dalam pembangunan ekonomi, 2) kelayakan Lembar Kegiatan Siswa terdiri dari kelayakan isi, kelayakan penyajian, kelayakan bahasa, dan kelayakan kegrafikan, serta kesesuaian dengan model pembelajaran yang dipilih, dengan rata-rata presentase sebesar 84,34%, dengan kategori sangat layak, 3) respon siswa diperoleh hasil rata-rata sebesar 94,58% dengan kategori sangat layak. Dengan demikian, Lembar Kegiatan Siswa (LKS) berbasis model pembelajaran Problem Based Learning (PBL) sangat layak untuk digunakan sebagai bahan ajar tambahan.
