Abstract

Corn is one of the leading food commodities in Indonesia, and it has a vital role in national food security. However, corn productivity often decreases due to the attacks of various types of plant diseases. Limited knowledge of farmers about the symptoms and types of corn diseases is one of the obstacles to proper and fast handling. Therefore, this study aims to build an expert system that can assist farmers in diagnosing corn diseases based on the symptoms shown. This system uses the Backward Chaining method, which tracks logic from conclusions (disease hypotheses) to the facts (symptoms) that support it. The tracing process is carried out until the appropriate facts are found to decide on the diagnosis of the disease. The system design is carried out using the prototype system development method. The testing is carried out by the Black Box Testing method to ensure that all system functions run as expected. The test results show that this expert system can provide accurate diagnoses, assist users in recognizing the type of corn disease, and provide treatment advice. Hopefully, this system can increase the effectiveness of handling corn diseases and support crop productivity.

Abstract

Penelitian ini bertujuan untuk mengembangkan Sistem Pendukung Keputusan (SPK) dalam pemilihan ketua, dengan menggunakan metode TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution). Metode TOPSIS digunakan untuk membantu proses pengambilan keputusan yang lebih objektif dan akurat dengan mempertimbangkan berbagai kriteria yang relevan. Hasil dari implementasi ini adalah sebuah sistem yang mampu memberikan perangkingan calon ketua secara efisien berdasarkan kriteria yang telah ditetapkan, sehingga mempermudah proses pemilihan dan meningkatkan transparansi. SPK berbasis metode TOPSIS ini telah terbukti efektif dalam berbagai kasus seperti pemilihan ketua RT/RW, ketua program studi berprestasi, dan pemimpin lainnya dalam organisasi
