Abstract

The problem in the Romaromi expedition which is addressed to Padangsidimpuan City, South Tapanuli Regency, Marancar District, precisely in Sugi Julu village which produces salak fruit is that the delivery of goods is done manually and irregularly where the goods are sent from the warehouse to the customer, and back to the warehouse, so it will cost a lot of time and also costs. Furthermore, to determine the allocation of consumers among existing routes, the sequence of routes that are able to go to all consumers from the specified route from vehicles that are able to pass all routes. Based on the problem in question, this study was made with a vehicle routing problem using Clarke and Wright savings or saving matrix by completing the calculation of savings measured from the many reductions between distance traveled and time used, involving nodes also making it one of the best route paths based on the greatest savings value, namely the distance traveled from the starting point to the intended end point. From the results obtained in data processing using Clarke and wright savings as many as 14 distribution routes. This shows that the Clarke and wright savings algorithm can minimize distance and also save company expenses.

Abstract

One of the coffee producers in North Sumatra is Karo Regency. Currently, the growth of coffee production in Indonesia is still hampered by the low quality of the coffee beans produced, which affects the development of the final coffee production. coffee, both in terms of selecting the best coffee beans and in terms of processing and benefits. To overcome this problem requires a system that can assist in making decisions regarding the selection of the best Arabica coffee beans with association pattern rules. As for applying associative rules to the selection of the best Arabica coffee beans in Tanah Karo between item combinations so as to form an itemset combination pattern and the Apriori Algorithm. Important association rules can be known with 2 parameters, namely, minimum support (the percentage of item combinations in the database) and minimum confidence (the strength of the relationship between items in the associative rules), both of which are determined by the user. The results of data mining calculations using the Apriori algorithm, data on the assessment of Mr. RM's coffee beans with a minimum support of 25% and a minimum confidence of 75%, form seven rules for Mr. RM's coffee beans. One of the best rules is that if the selection of Normal Bean Presentation is on the Andungsari 1, Andungsari 2, and Komasti coffee varieties, then with a 100% probability the selection on Leaf Rust Resistance will also be good for the selection of Andungsari 1, Andungsari 2, and Komasti coffee varieties. The best selection combination is {BN,B,KD,A} with a 100% confidence level and has the highest lift value, namely, 3.70.

Abstract

The Sipirok woven fabric industry is one of the industrial characteristics of South Tapanuli Regency in North Sumatra. In general, the challenges encountered in the industry are related to production optimization. There have been numerous research on production optimization that use mathematical methods such as the simplex method. However, the simplex technique has limits, as it only has one objective function. As a result, the Fuzzy Multi-Objective Linear Program method is employed in this study. Because Fuzzy Multi-Objective linear program includes two objective functions, maximizing profits and reducing/minimizing processing time, it can be used to tackle optimization issues in the Sipirok woven fabric company. This sort of research employs primary data, specifically interviews and direct observation at the research site, the Sipirok Woven Fabric Industry. This study's calculations were supplemented by the simplex method, which was then followed by the two-phase simplex method to generate the ultimate outcome of woven fabric manufacture. The woven fabric industry now produces 472 units of Samuel's woven fabric, with a maximum profit of Rp. 37,920,000 and a minimum processing time of 7,110 hours, where the variable value λ is 0.10 to represent the maximum degree of each objective function.

Abstract

This study applies the Naïve Bayes method to diagnose coronary heart disease (CHD) in Medan City. This quantitative study uses secondary data from Malahayati Islamic Hospital, including independent variables (age, gender, smoking, blood pressure, family history) and dependent variables (CHD status). The data are divided into training data (90%) and testing data (10%). Despite the high accuracy, further research with larger and more diverse data is needed to validate these findings. The Naïve Bayes method has proven potential as an aid in the early diagnosis of CHD.
