Abstract

The use of pesticides in agriculture plays a role in preventing and reducing diseases in chili plants. Pesticides for chili plants are quite widely spread on the market and have the advantages of each product offered to farmers, so farmers must be more careful and understanding in choosing pesticides to be used in preventing chili plant diseases. For that we need a decision support system (SPK). The data used in this research are 10 types of pesticides as an alternative. While the criteria are determined based on the agriculture and food service, namely price, classification, number of diseases eradicated, method of action, shelf life, and formulation concentration. Data analysis uses the MOORA method to support decision making for farmers in providing an assessment of the best pesticides on chili plants. The research results obtained for the three best pesticides are Tridex 80 WP, Lamzeb 85 WP, and Ziflo 76 WG.

Abstract

Kospin Jasa is a savings and loan cooperative founded in the 1970s by several small entrepreneurs. It is established to overcome difficulties in obtaining capital loans because businesses are still managed traditionally. Therefore, on December 13, 1973, Mr. HA Djuanaid (Alm), a national cooperative leader, met and agreed to establish a savings and loan cooperative. With the rapid development of information technology, companies/organizations have the opportunity to increase productivity. The application of information technology supports increased competitiveness with competitors. Management of information technology should then be audited. Typically, the necessary controls are provided by COBIT. This article is here to discuss information technology management which impacts cost overruns. This paper collects data through library research using qualitative methods. The results obtained are in the form of an IT governance design plan and are taken from COBIT 2019

Abstract

Gender prediction is a form of prediction programme that outputs a gender type. In the research conducted in this case study, we used input in the form of text names of Indonesian people. Nowadays, there are many names of people that sometimes sound quite ambiguous and make us confused whether this person is MEN or WOMEN. From this case study we are looking for ways to use the Long short term memory method to predict and classify the names of Indonesian people to find out their gender based only on the name with the aim of improving science and looking for new innovations to support future research. The research limitations are the names used are Indonesian names because the dataset used is a dataset of Indonesian names and also the gender we classify is only 2 types of gender, namely MEN and WOMEN. The accuracy comparison of the training results of the baseline programme and the modified programme is the accuracy for the baseline programme of around 0.93, while the accuracy for the modified programme is around 0.90. The results showed an increase in accuracy after experimenting with testing data on the modified programme, which was 0.96.

Abstract

Paper search engines have made it easier for academics to conduct literature reviews. However, easy doesn't mean accurate. For certain niche topics, search results often aren’t quite good. Snowballing can be done to overcome this, but it is limited to the initial articles owned, especially the author's access when the article was written. As an alternative, paper databases provide recommendations for relevant articles of an article, but it’s limited to that database. A tool to search for similar articles without relying on a specific database would be very helpful, but before that, the appropriate method for measuring article similarity needs to be determined. This research aims to measure article similarity based on title, author, and keywords using Weighted Jaccard Measure and Levenshtein distance and evaluate it. This study also compares performance by adding blocking with overlap blocking and stop word removal. The Jaccard evaluation results are quite poor, but the Levenshtein + Jaccard evaluation results are decent. In addition, it was found that emphasizing weighting on the title produces the best results. Overlap blocking and stop words removal increases processing time instead. Overlap blocking can reduce the number of measurements by almost half with an overlap of 1, but overlaps above 1 will discard many pairs that should be similar. Removing stop words improves Jaccard and Levenshtein performance but requires threshold adjustment.

Additionally, in the production process, Babyje has Bill of Material data for each of its products. Therefore, product inventory management and raw material requirement planning are important stages in the production process. However, Babyje experienced product supply problems due to unstable market demand. In July 2022 the Babyje experienced stockouts and overstocks with the same percentage, namely 50%, while in August they tended to experience overstocks with a percentage of 80% and in September tended to experience stockouts with a percentage of 70%. This phenomenon can increase storage costs and hinder buyer demand. This study uses the waterfall method for software development and the min max method for product inventory control. The purpose of this research is to produce a product inventory control application using the min max method. The results of implementing the application with the min max method can remind the business when it is the right time to restock, as well as provide recommendations for the number of orders that must be restocked. Based on the results of black box testing with a total of 120 test cases carried out by 2 user roles, all functionality goes well with a 100% success rate, and for user acceptance testing, all user roles have accepted applications with an acceptance percentage of 100%. The results of this application can calculate the difference between the number of orders that should be the number of orders suggested through the system. From the results of these calculations, there is a relative error in system calculations with a percentage of 14.02%.

Abstract

Information technology governance (ITG) is organizational management that aims to ensure the implementation of IT is carried out effectively and efficiently in realizing organizational goals. ITG in ensuring the implementation of IT, through measuring the effectiveness and efficiency of business processes, use of resources, risk management, and improvement of organizational performance. Therefore, ITG has now become the focus of organizational leaders in general and is the core of IT success in organizations. Meanwhile, the success of ITG in an organization is largely determined by the alignment between IT and organizational goals. This alignment can be realized by planning ITG. In making ITG planning, a framework is needed, namely COBIT. Therefore, ITG planning is important for the organization, so that the implementation of IT can be maximized and provide benefits for the organization. On this basis, a narrative review was carried out to explore the ITG planning research based on the COBIT 5 lifecycle. In exploring this research, it is based on formulation planning, implementation, and evaluation. The results of the narrative review which is based on research for the 2018 to 2023 period resulted in a formulation plan but not yet an implementation and evaluation plan. In planning the formulation is only limited to providing recommendations but is not accompanied by an implementation and evaluation plan of the recommendations. For this reason, the results of this narrative review can be used as a basis for further research on ITG planning based on the COBIT 5 lifecycle.
