Abstract

With the largest population in Indonesia, Bogor Regency in West Java Province has agricultural potential. One of the prospective regions in Region V with agricultural populations that grow both fresh and processed agricultural products, from rural to urban. Problems in the promotion of agricultural products were discovered by the Government of Bogor Regency through the Agricultural Extension Center of Region V. To solve these issues, a platform called Kiosagri.com in the form of a marketplace has been introduced. It is required to quantify usability, which is influenced by the usability dimension, for this market to be useful. As a result, the purpose of this study is to examine the usability factors that influence the usability of the farmers that utilize the Kiosagri.com agricultural marketplace. This reserach employs a cross-sectional survey design and a quantitative methodology. Farmers who have been introduced to Kiosagri.com were the only respondents in the census. 32 respondents' data were analyzed using multiple linear regression tests and descriptive statistics. The findings demonstrated a substantial relationship between usability and the usability factors of learnability, efficiency, memorability, error, and satisfaction. Only efficiency, which has a substantial impact on usability, is the dimension that dominates this relationship.

Abstract

Diagnosing liver disease in the field of healthcare is not an easy task. However, by utilizing medical records as datasets and applying data mining methods such as K-Nearest Neighbor (K-NN), we can analyze and extract knowledge automatically. The K-NN method has proven to be more effective compared to other methods as it clusters new information by selecting the nearest neighbors based on the value of k. In this study, we employed the Elbow method to determine the optimal value of k by measuring the error rate. The test results revealed that the optimal value of k was found to be 4, with the lowest error rate. In the third test, we achieved a training accuracy of 80.5% and a testing accuracy of 78.9%. After fine-tuning the training data, we were able to improve the accuracy to 82.2% for training and 77.1% for testing. However, in the fourth test, we encountered overfitting issues due to data imbalance caused by inappropriate resampling, resulting in a model that was overly complex and prone to excessive noise.

Abstract

Object recognition is a type of image processing technique that is frequently employed in current applications such as facial identification, vehicle detection, and automated cashiers. One issue with barcode and RFID cashier apps is that they cannot scan several products at the same time. The cashier application employing object identification using picture images is believed to be able to distinguish more than one object in order to speed up the transaction process. The usage of SSD pre-trained models with MobileNet architecture to detect items in automatic cashier applications is discussed in this paper. This study put the model to the test on three types of soft drink objects: coca-cola, floridina, and good day. A smartphone camera was used to collect the data, which totaled 203 images. The findings indicated that the product object identification method was 82.9% accurate, 97.5% precise, and 84.7% recall. The object recognition process takes between 365 and 827 milliseconds, with an average time of 695 milliseconds (0.69 seconds).

Abstract

The department is part of the faculty, and is the focus of the field of study chosen by students. The choice of majors is very important to think about beforehand because it will have an impact on the results of these graduates and the job prospects sought later. There are many things that can be considered by high school graduates in choosing a major because if you choose rashly, you will be at risk of failing along the way. For this reason, research was carried out with an emphasis on the criteria for selecting majors at ISB Atma Luhur. The method used in this study is SAW (Simple Additive Weighting) which is a weighted sum method that is weighting criteria and alternative attributes so that normalization can be carried out and calculation of preference values is carried out and the highest and lowest rankings are obtained which are used as decision recommendations. Respondent data was taken based on the sample, namely through a non-probability sampling technique, namely in this study the respondent could only provide one opportunity to be sampled from the population so that one respondent could not be sampled twice. Respondents who were sampled were 100 people who were taken from high school graduates. The criteria presented include department accreditation, number of professionally certified lecturers, study program scholarships, and facilities. Determination of criteria based on the results of interviews with respondents and the results are taken based on the criteria with the most choices. The results of the study are alternative Information Systems with a weight or value obtained from the SAW calculation results, namely 1, Informatics Engineering with a weight of 0.8, while Digital Business is 0.6. From the results of these calculations, it can be concluded that the department that gets the highest score, namely the Information Systems major, can also be used as a recommendation as a major to be chosen by students.

Abstract

In the field of microbiology, the counting of bacterial colonies is fundamental and mandatory. This is done to estimate the number of bacterial cells in every 1 milliliter or gram of sample. The counting takes a long time and is tedious, so it requires an accurate and fast counting method. The image quality used is very low and contains noise. Therefore, a preprocessing method is needed to reduce the noise. The Perona-Malik filter method is known to be able to remove noise well. However, it is difficult to determine the appropriate gradient threshold parameter ( ) for each different image. To find the appropriate value of , the original Sobel Mask method and Sobel Mask Fractional-Order are used to estimate the value of . The experimental results show the results of noise reduction using PMD with a value of  from the original Sobel Mask and Sobel Mask Fractional-Order. The results of the accuracy of determining the value of k with the Sobel Mask Fractional-Order (α=1.0) show higher results based on the F-Measure values for samples 1, 2, and 3 respectively 97%, 98%, and 90%.

Abstract

The increasingly complex business environment necessitates businesses to design more effective and efficient strategies for company development, including market expansion. To understand customer behaviors, customer data analysis becomes crucial. One common approach used to group customers is segmentation based on RFM analysis (Recency, Frequency, and Monetary). This study aims to compare the performance of two clustering algorithms, namely DBSCAN and Affinity Propagation (AP), in providing customer profile segment recommendations using RFM analysis. DBSCAN algorithm is employed due to its ability to identify arbitrarily shaped clusters and handle data noise. On the other hand, Affinity Propagation (AP) algorithm is chosen for its capability to discover cluster centers without requiring a pre-defined number of clusters. The transaction dataset used in this research is obtained from one of the business incubator tenants at STIKOM Bali. The dataset undergoes preprocessing steps before being segmented using both DBSCAN and AP algorithms. Performance evaluation of the algorithms is conducted using the Silhouette Scores and Davies-Bouldin Index (DBI) matrices. The research findings indicate that the AP algorithm outperforms DBSCAN in this customer segmentation case. The AP algorithm yields Silhouette Scores of 0.699 and DBI of 0.429, along with recommendations for 4 customer segments. Furthermore, further analysis is performed on the AP results using a statistical approach based on the mean values of each segment for the RFM variables. The four customer segments generated by the AP algorithm, based on the mean values of the RFM variables, can be associated with the concept of customer relationship management.

Abstract

Empowering SMEs in the midst of globalization and high competition has forced MSMEs to face global challenges, such as increasing innovation, developing human resources and technology, and expanding the marketing area. Social networks provide a medium for processing new innovations for SMEs such as relationships with customers, work partners and also suppliers. Business process management can assist business actors in carrying out their business activities in the face of today's challenges and global competition. This study reveals that every business process can be supported by the implementation of IT by a company. This study uses a grounded theory approach. Grounded theory studies tend to follow a structured approach. This research uses case studies of hydroponic SMEs in Indonesia, which produce the types of social media social media functions that are often used by Indonesians. The main strength of this research is the functions of social media needed by SME actors. From the results of the study it was found that SMEs need social media functionality in 4 functions, namely: the interaction function, the marketing function, the reputation function, and the information function. SMEs in Indonesia need applications that contain these 4 functions to be able to market, sell, and interact with other people.
