Abstract

The purpose of this business capital assistance program is to help people develop businesses that were previously affected by the Covid-19 pandemic which caused small businesses such as street vendors and home businesses to experience a decrease in income. This program aims to help small and medium enterprises (MSMEs). Potential beneficiaries are currently still selected through meetings held by village heads, which require a longer decision-making process.Therefore it is very important to create a new system that can be used to assist those who are eligible to receive targeted funds. In this study, a decision support system application was made to make it easier for village heads to determine candidates who are entitled to receive assistance according to the criteria. A decision support system is a solution that can be used to find out the results of the selection of MSME beneficiaries using the SAW and SMART methods. The SAW and SMART methods use 10 alternative data to provide an assessment of the final result by ranking from the highest to the lowest alternative value, showing that the two methods produce data that is accurate and suitable when applied as a ranking. The calculation results generated by the system that has been tested with the results of manual calculations, both show the same results.

Abstract

The government and institutions in an area have developed a program known as the RKPD (Regional Development Work Plan), which is an elaboration of the RPJMD (Regional Medium Term Development Plan). However, the Medan City Regional Development Planning Agency faces several problems in the development stage in the regions, including consideration of priority scales and elements of justice as well as a lack of a decision support system to determine development priority scales. Therefore, the Agency needs an appropriate system to determine development priorities, and one of the systems that can help solve this problem is the Decision Support System (SPK). The method used is SAW which was chosen because it is expected to provide effective results in determining the priority of regional development programs at the Medan City Regional Development Planning Agency. The research resulted that the regional highway development program with a value of 0.77705 has the highest priority to be prioritized for regional development programs at the Medan City Regional Development Planning Agency, because it has the highest ranking when compared to other alternatives.

Abstract

Penjualan merupakan hal yang tak terpisahkan dari kehidupan sehari-hari, di mana setiap orang secara rutin melakukan transaksi jual beli yang berdampak besar bagi pertumbuhan ekonomi. Bagi para pebisnis yang bergerak di bidang penjualan, seperti pemilik coffee shop, strategi untuk meningkatkan jumlah penjualan dan laba menjadi hal krusial. Dengan aktivitas transaksi harian yang terus meningkat, data penjualan tersebut bukan sekadar arsip biasa, melainkan memiliki potensi untuk diolah menjadi informasi berharga guna meningkatkan penjualan. Namun, seringkali terjadi masalah ketika stok item yang diinginkan oleh konsumen tidak tersedia atau habis karena kurangnya pengelolaan stok yang baik oleh karyawan coffee shop. Akibatnya, data transaksi penjualan yang ada hanya terabaikan dan tidak dimanfaatkan secara optimal, menyebabkan kerugian karena persediaan menu tidak terkontrol dengan baik. Sebaliknya, data transaksi sebelumnya dapat digunakan untuk mengidentifikasi pola pembelian pelanggan, sehingga dapat diambil kesimpulan bahwa jika pelanggan membeli menu A, kemungkinan besar akan membeli menu B juga. Untuk mengatasi permasalahan tersebut, solusi yang dapat diterapkan adalah memanfaatkan data transaksi penjualan yang telah terkumpul. Data ini mengandung informasi berharga yang bisa digunakan untuk pengambilan keputusan dan memperoleh pengetahuan baru tentang pola penjualan di coffee shop, sehingga pengelolaan persediaan menu dapat lebih terstruktur dan jumlah persediaan menu yang tidak diminati dapat dikurangi. Untuk mencapai persediaan yang ideal, peneliti menggunakan metode Data Mining, khususnya metode Assosiasi dengan Apriori. Namun, pencarian support hanya dilakukan hingga 3 set item tanpa ditemukan kombinasi yang memenuhi batas minimum support, sehingga proses tersebut dihentikan. Untuk melanjutkan pencarian nilai confidence, digunakan gabungan 2 set item (L2) yang memenuhi syarat untuk membentuk asosiasi. Hasil analisis dengan metode ini menghasilkan tiga aturan asosiasi yang berharga untuk meningkatkan penjualan, yaitu "Jika membeli cappuccino maka akan membeli donat" dengan confidence 0,65, "Jika membeli donat maka akan membeli cappuccino" dengan confidence 0,93, dan "Jika membeli muffin maka akan membeli cappuccino" dengan confidence 0,83.

Abstract

Diseases in tomato plants have a significant impact on the agriculture industry as they can reduce crop yields and tomato quality. Therefore, this research aims to compare the Bayesian Theorem and Case-Based Reasoning (CBR) methods in diagnosing tomato plant diseases. The Bayesian Theorem is a statistical approach based on probability, while CBR uses knowledge from previous cases. This study includes an analysis of the performance of both methods in terms of diagnostic accuracy, result delivery speed, and resource efficiency. The research results have the potential to assist farmers and agricultural experts in choosing the most suitable method for diagnosing tomato plant diseases. Furthermore, the implementation of expert systems in agriculture can have a positive impact on tomato cultivation productivity and sustainability. This research aims to provide practical guidance for stakeholders in the agricultural field and contribute to sustainable agriculture improvement, with a specific focus on disease identification and management in tomato plants. The percentage values of the application of the Bayesian Theorem and Case-Based Reasoning methods show that Case-Based Reasoning has a lower success rate in diagnosing Fusarium Wilt and Bacterial Wilt compared to the Bayesian Theorem. However, Case-Based Reasoning excels in diagnosing Tomato Yellow Leaf Curl Virus (TYLCV), achieving a success rate of 100%, while the Bayesian Theorem reaches 63%.

Abstract

Varicella, another name for smallpox, is a viral infection that primarily affects children and can cause an itchy rash on the skin and fever. Smallpox should be diagnosed as soon as possible to stop the spread of the disease and provide appropriate treatment. The aim of this study was to compare the Dempster-Shafer and Certainty Factor (CF) approaches for diagnosing smallpox. The main aim of this study was to evaluate the effectiveness of both methods in detecting smallpox and to determine which is more accurate and reliable in the diagnosis process. The CF method is an approach in artificial intelligence that uses confidence factor values to describe an expert's level of confidence in an event or statement. Meanwhile, Dempster Shafer is a combined theory that can overcome uncertainty in decision making by modeling the level of confidence in various aspects. This research will outline the basic concepts of the Certainty Factor method and Dempster-Shafer Theory, as well as analyze their application when making a diagnosis of smallpox. The level of precision, dependability, and effectiveness of each technique will be compared. It is hoped that health professionals can improve smallpox diagnosis and make better clinical judgments with the help of the results of this study. The results of this research will help medical personnel and health practitioners make better decisions in diagnosing smallpox. Apart from that, this research can also help reduce diagnostic errors and speed up the treatment process. The calculation results from this research show that for Shingles, the Dempster Shafer approach produces a success rate of 86%, while the Certainty Factor method offers a success rate of 99%.

Abstract

Appropriate Account Receivable staff must be qualified, have skills, and exhibit traits that are suitable for the duties and responsibilities associated with receivables management. Errors in staff selection can potentially create problems in the management of receivables, result in delays in the collection of funds, and pose a greater risk of loss to the company. Therefore, the selection and selection of qualified Account Receivable Staff is a very key factor in achieving optimal financial performance. Selection in the selection of Account Receivable staff has several criteria, namely Education, Experience, Technical Skills, Communication Skills and Negotiation Skills. In the midst of an increasingly complicated business environment and intense competition, the use of decision support systems (SPK) is becoming more relevant to assist in the optimal employee selection process, given the importance of objectivity and accuracy in the selection process by applying the ROC (Rank Order Centroid) and WASPAS (Weighted Aggregated Sum Product Assesement) methods which are utilized to provide weight values to the selection criteria, while WASPAS is used to verify the results of the selection decision. So that the best Account Receivable Staff selected is alternative A5 with the highest value of 3.8354 as the first rank.
