This study aims to develop a web-based expert system that can identify cassava disease using Case-Based Reasoning Method and Shafer Dempster Method, and to know the performance comparison of both based on the accuracy of identification. Case-Based Reasoning (CBR) is a computer-generated system that uses old knowledge to solve new problems. CBR provides solutions to new cases by looking at the oldest cases that are closest to new cases. The identification process is done by entering new cases containing the symptoms to be identified into the system, then perform the process of calculating the value of similarity between the new case and the base case using the nearest neighbor method. Dempster Shafer based on two ideas is the idea of obtaining degrees of confidence of subjective possibilities and the rule of dempster safer itself to combine degrees of confidence based on the evidence obtained. This expert system is built using PHP programming language and MySQL data base. The output of the system is the percentage of identification result of both methods. Testing and analysis results show that Case-Based Reasoning provides better identification accuracy than Dempster Shafer.

<p class="Judul2" align="left"> </p><p>Tanaman nilam menghasilkan minyak nilam (<em>patchouli oil</em>) yang digunakan sebagai bahan baku kosmetik, parfum, antiseptik, sabun, obat, dan insektisida. Dalam pengembangan dan peningkatannya tanaman nilam mengalami beberapa kendala seperti serangan hama dan penyakit yang mengakibatkan rendahnya hasil panen khususnya pada daerah Desa Gunung Sari Kecamatan Watubangga Kabupaten Kolaka. Pengembangan tanaman nilam yang terserang hama dan penyakit seringkali terhambat karena masih banyak petani yang tidak mengetahui jenis hama dan penyakit yang menyerang tanaman petani. Oleh sebab itu sistem pakar berbasis kasus atau <em>Case Based Reasoning (CBR)</em> dibangun untuk mendiagnosis jenis hama dan penyakit tanaman nilam. Pada penelitian ini digunakan 7 jenis penyakit dan 22 gejala berdasarkan studi kasus tempat penelitian. CBR menggunakan metode<em> similarity</em> Nearest Neighbor untuk menemukan kemiripan antar kasus yang berada dalam tahapan <em>retrieve</em>. Pada penelitian ini digunakan juga metode lain yaitu Certainty Factor yang berfungsi untuk mengetahui derajat kepercayaan terhadap hasil diagnosis sistem dalam menghasikan jenis hama dan penyakit tanaman nilam. Berdasarkan hasil penelitian dengan menggunakan kombinasi dua metode Nearest Neighbor dan Certainty factor maka dihasilkan sistem mampu melakukan diagnosis hama dan penyakit tanaman nilam dengan nilai <em>similarity</em> 0.7 dan tingkat kepercayaaan sebesar 97,2 %  serta menghasilkan tingkat akurasi sistem sebesar 93.82 % dan tingkat kesalahan sistem 3 %</p><div><p> </p><p><em><strong>Abstract</strong></em></p><p><em>Patchouli oil is used as a raw material for cosmetics, perfumes, antiseptics, soaps, medicines, and insecticides. In the development and improvement of patchouli plants experienced several obstacles such as pests and diseases which resulted in low yields, especially in the area of Gunung Sari Village, Watubangga District, Kolaka Regency. The development of patchouli plants attacked by pests and diseases is often hampered because there are still many farmers who do not know the types of pests and diseases that attack farmers' crops. Therefore a case based reasoning (CBR) expert system was built to diagnose patchouli plants and pests. In this study 7 types of diseases were used and 22 symptoms were based on the case study site. CBR uses the similarity Nearest Neighbor method to find similarities between cases that are in the retrieval stage. In this study, another method is used, namely Certainty Factor, which functions to determine the degree of trust in the results of system diagnosis in producing patchouli species and diseases. Based on the results of the study by using a combination of the two Nearest Neighbor and Certainty factor methods, the system was able to diagnose patchouli pests and diseases with a similarity value of 0.7 and a confidence level of 97.2% and produce a system accuracy rate of 93.82% and a system error rate of 3%</em></p><p><em><strong><br /></strong></em></p></div>

<p>Ikan Gurami (<em>Osphronemus Goramy)</em> merupakan ikan yang banyak dibudidayakan dan dikomsumsi masyarakat ini menjadi sektor unggulan di beberapa wilayah kabupaten Banyumas. Ikan gurami yang dibudidayakan oleh masyarakat Banyumas, sebenarnya bukan tanpa hambatan. Salah satu hambatan bagi peternak gurami adalah penyakit yang disebabkan oleh bakteri. Pada penelitian ini penulis membuat sistem pakar untuk mendiagnosis penyakit ikan Gurami yang disebabkan bakteri. Penelitian ini menggunakan metode<em> Case Based Reasoning</em> dan <em>Similarity</em> <em>Nearest Neighbor</em> untuk mendapatkan solusi yang terbaik dari kasus yang di identifikasi. Metode tersebut membandingkan antara kasus lama dengan kasus baru dan menghitung suatu nilai <em>similarity </em>kasus. Nilai <em>similarity</em> tertinggi dapat dijadikan kesimpulan untuk kasus yang paling mirip dengan diagnosa pakar. Sehingga dari kedua metode tersebut dapat dihasilkan sistem pakar yang dapat mendiagnosis dan menganalisis sesuai dengan nilai kemiripan gejala terhadap penyakit, serta menampilkan solusi penanganan dari penyakit yang didiagnosis. Hasil pengujian antar kasus dan sistem menggunakan perhitungan <em>similarity</em> mencapai nilai terbaik yaitu 100%. Hasil pengujian akurasi sistem untuk diagnosis yang sesuai dengan pikiran pakar, memperoleh hasil sebesar 93,33% dari 30 kasus yang diuji dengan sistem. Kesimpulan dari hasil tersebut adalah sistem dapat dikatakan layak untuk mendiagnosis penyakit Gurami yang disebabkan bakteri sesuai dengan yang dipikirkan pakar.</p><p> </p><p><em><strong>Abstract</strong></em></p><p><em>Gurami (Osphronemus Goramy) is a fish that is widely cultivated and consumed by the community. This fish is a leading sector in several regions of Banyumas district. Gouramy which is cultivated by the Banyumas people, is actually not without obstacles. One obstacle for gouramy breeders is a disease caused by bacteria. Reporting from the online news portal, circulating in February 2018 circulated that news about Gurami farmers was losing money because thousands of broodstock fish that had been raised to death were attacked by bacterial diseases, namely Aeromoniasis. Experts who handle this are limited, namely only 2 people in the Banyumas Regency.</em><em> </em><em>In this study the authors made an expert system to diagnose Gurami fish disease caused by bacteria. This study uses the Case Based Reasoning (CBR) and Nearest Neighbor methods used to get the best solution from the identified case. The CBR method compares the old case with the new case and calculates a case similarity value. The system was built with 13 symptoms and 3 Gurami diseases caused by bacteria. Each symptom each has a weight of 5, 3, and 1. The highest similarity value can be used as a conclusion for the case most similar to the expert diagnosis. So that from these two methods an expert system can be produced that can diagnose and analyze according to the similarity of symptoms to the disease, as well as display solutions to the treatment of diagnosed diseases. The test results are between cases and the system uses the similarity calculation to achieve the best value of 100%. The results of the system accuracy test for diagnoses that are in accordance with the expert's mind, obtained results of 93.33% from 30 cases tested with the system. The conclusion of these results is that the system can be said to be feasible to diagnose Gurami disease caused by bacteria according to what experts think.</em></p><p><em><strong><br /></strong></em></p>

Culinary is one of the favorite businesses today. The number of considerations to choose a restaurant or place to visit becomes one of the factors that is difficult to determine the restaurant or place to eat. To get the desired place to eat advice, one needs a recommendation system. Decisions made by the recommendation system can be used as a reference to determine the choice of restaurants. One method that can be used to build a recommendation system is Case Based Reasoning. The Case Based Reasoning (CBR) method mimics human ability to solve a problem or cases. The retrieval process is the most important stage, because at this stage the search for a solution for a new case is carried out. The study used the K-Nearest Neighbor method to find closeness between new cases and case bases. With the selection of features used as domains in the system, the results of recommendations presented can be more suggestive and accurate. The system successfully provides complex recommendations based on the type and type of food entered by the user. Based on blackbox testing, the system has features that can be used and function properly according to the purpose of creating the system.
