Perkembangan teknologi informasi telah mencakup segala bidang kehidupan, termasuk bidang pertanian. Salah satu bidang pertanian yang sedang dikembangkan ialah pertanian lada (Piper ningrum L). Dalam perkembangannya tanaman lada dapat terjangkit penyakit yang akan berpengaruh pada hasil panen yang akan diterima oleh petani. Penelitian ini mengembangkan suatu sistem pakar penyakit yang menyerang tanaman lada dengan metode Certainty Factor dan menggunakan penelusuran inferensi Forward Chaining. Sistem pakar merupakan bagian dari kecerdasan buatan, dimana sistem mengadopsi pengetahuan manusia yang ahli ke dalam komputer untuk menyelesaikan suatu pekerjaan yang biasanya memerlukan kepakaran seseorang. Penelitian ini dilakukan di UPTD Pengembangan Perlindungan Tanaman Perkebunan Provinsi Kalimantan Timur. Terdapat enam penyakit yang menyerang tanaman lada yaitu penyakit busuk pangkal, penyakit kuning, penyakit keriting daun, penyakit jamur pirang, penyakit karat merah dan penyakit bercak daun Colletotrichum. Pada implementasi sistem dilakukan pengujian dengan memilih beberapa gejala yang menyerang tanaman lada antara lain daun berubah warna, terdapat bercak pada daun, daun menguning, pangkal batang berubah warna, akar mengalami pembusukan, pangkal batang berwarna coklat, dan akar berwarna hitam. Berdasarkan gejala yang dipilih pengguna tersebut, diperoleh hasil berupa identifikasi penyakit busuk pangkal batang dengan nilai Certainty Factor sebesar 88.57% yang berarti bahwa tanaman lada tersebut hampir pasti terkena penyakit busuk pangkal batang.
