Abstract

This study scrutinized four CMMS (Computerized Maintenance Management System) development projects using the K-Means clustering method to evaluate stages that require improvement by the GrX team. The projects under consideration were named Tim, Lix, Akb, and Mnk. The results indicated that the Tim project leaned more towards efficient CMMS development stages, while the Lix and Akb projects were predominantly in less efficient clusters at the implementation stages. The Mnk project had stages in less efficient clusters located at stages other than implementation processes. This suggests that each project has its unique challenges in achieving efficiency. However, the overarching conclusion is that the GRX team needs to enhance efficiency in the CMMS software development process. Several stages need to be evaluated, particularly the “data analysis and coordination” and “implementation of asset, work order, preventive and spare part modules” stages. Inefficiency occurs when the designing work time has a value lower than twice the workload. The K-Means algorithm was employed in the clustering process because it was believed that the data to be grouped was well-suited for implementation with this algorithm. The variables involved in this study were time and workload. This research provides valuable insights into the efficiency of CMMS development projects and offers a roadmap for future improvements.

Abstract

This research was motivated by the low level of student creativity in the class X informatics subject at SMK Negeri 2 Tulungagung. The purpose of this research is to determine the effect of implementing the Problem Based Learning learning model on the creativity of class X students at SMK Negeri 2 Tulungagung. This type of research is a quasi-experiment with a post-test only control group design. The samples from this research were taken from 2 classes X AKL of SMK Negeri 2 Tulungagung. The experimental class is taught using a problem based learning model and the control class uses a conventional learning model, namely using the discovery learning model. The posttest score results for the experimental class had an average of 86.83 and for the control class the average posttest score was 77.69. Based on the results of the hypothesis test, a sig = 0.000 value was obtained at the significance level  = 0.05. This means that the sig value 0.05 means the sig value is outside the H0 acceptance area. So it can be concluded that there is an influence of the problem based learning model in informatics subjects on the creativity of class X students at SMK Negeri 2 Tulungagung

Abstract

In the era of technological development and information is increasingly widespread. Data and information are easier to obtain using current technology, especially using social media such as Instagram, Facebook, (x) Twitter and others. In social media, information can be in the form of public opinions containing praise, hate speech, and hoaxes which can result in arguments against the information presented, especially on the x (twitter) application. Therefore, research was conducted on sentiment analysis of positive and negative opinions of Indonesian people on application x (twitter) about ChatGPT using the naive bayes method. Basically, Naive Bayes looks for the largest conditional probability value for each class. The technique used to explore public opinion data on application x (twitter) about ChatGPT is google collabs with the results of data mining as much as 1012 data. of these 1012 data cleaning and sentiment analysis using the naive bayes method. Naïve Bayes method classification results with a total of 762 twitter comments about ChatGPT. 100 are used as training data modeled using the naïve bayes method. The accuracy value is 99.00%, positive prediction precision is 100%, negative prediction precision is 96.43%, positive data recall is 98.63%, and negative data recall is 100%.

Abstract

Cricket production in Indonesia has promising business potential, particularly in rural areas. However, production variability is often a major challenge for farmers to maintain economic stability. Therefore, production forecasting methods are needed for better management. This study aims to predict cricket production using Moving Average (MA) and Weighted Moving Average (WMA) methods and compare their accuracy. The research was conducted in Rejotangan District, Tulungagung, using 12 weeks of cricket production data from May to August 2024. The accuracy of the method was measured using Mean Absolute Deviation (MAD), Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE). From this research, the best model that can be used to predict the amount of cricket production is the Weighted Moving Average (WMA) model with n = 4 with the lowest prediction accuracy value (MAD, MSE and MAPE) of 16.05, 514.513 and 10.985% respectively. From the forecasting results, the total production of crickets in the existing farm for one period ahead with the WMA model n = 4 is 150.9 kg.

Abstract

Preventive maintenance is one of effort in manufacturer industry to maintain an infrastructure that has an important thing in the industry. One of module that was provided from this system, like service and maintenance or Work Order (WO). This module has behavior data like brain jobs in human beings. Where is the data that record in memory used to learn to get a solution in the next experienced because the data WO be saved like data in the market basket analysis. The transaction data may be repeated in the next problem. So this data is interesting to be processed to get the best solution by involved it as machine learning like the recommended solution in the brain of human beings. This research will be focused on using fp-growth association rule as unsupervised machine learning to process data as a recommended solution for the technician. A different method like previous research using apriori algorithm. This research has a goal to prove the effect of minimum support with the result of decision support in fp-growth algorithm. The study shows the best condition of the result in this method is between 0.002 until 0.004 for minimum support, because the best precision ,recall, and accuration value more than 50% in that range of minimum support.

Abstract

AbstrakPerkembangan pengambilan keputusan telah semakin cepat dan metode yang digunakan beragam. Sehingga perlu adanya pengambilan keputusan yang tidak hanya cepat tapi juga tepat. Salah satunya yaitu penerapan sistem pendukung keputusan pada Computer Maintenance Management System (CMMS). Penelitian ini melakukan uji data dengan menggunakan Association Rule, Fisher Exact One Side P-Value dan double one side p-value dalam satu permasalahan yang sama pada Computer Maintenance Management System (CMMS). Dengan tujuan mencari pola hubungan antara gejala dan akar permasalahan, untuk membuktikan adanya hubungan kedua variabel. Pada penelitian yang dilakukan sebelumnya (Sukmana, Bulaili) tentang Association Rule dan Pearson Chi-Square pada CMMS menunjukkan adanya beberapa rule yang tereliminasi karena adanya beberapa rule yang tidak masuk dalam kriteria untuk penerapan pada Chi-Square. Sehingga dalam penelitian ini bertujuan menggunakan metode Chi-Square lain dengan maksud membuktikan dan memperkuat adanya hubungan atau relasi antara gejala dan akar permasalahan dalam CMMS. Dan diharapkan pembuktian ini akan menunjukkan hasil lebih baik dalam hal hubungan antara gejala dan akar permasalahannya memiliki korelasi.Kata kunci: Association Rule, Fisher Exact TestAbstractDecision-making has been growth rapidly and many methods can used. Thus, how to apply that methode not only fast but also right. One of implementation decision making is decision support system in Computer Maintenance Management System (CMMS). This research using data test with Association Rule and Fisher Exact One Side P-Value from same problems in Computer Maintenance Management System (CMMS). Object from this research to get pattern of association between symptom and root cause, to prove relation those variable. Previous research (Sukmana, Bulaili) about Association Rule and Pearson Chi-Square in CMMS show some rule was elimanated from calculation, becaise that is rule out of way from criteria in Chi-Square. So this research has objective to use another methode to observe and get strength evidence about correlation between symptom and root cause in CMMS. And hope with this result of test can make strength hypothesis about relation between symptom and root cause.          Keywords: Association Rule, Fisher Exact Test
