User Acceptance and Effectiveness of AutoML Systems in Predicting Training Success: A Case Study of the DTS Program
type: item
link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5909
description: The advancement of digital technologies has transformed workforce demands, emphasizing digital literacy, adaptability, and innovation. Indonesia’s Digital Talent Scholarship (DTS) program, launched in 2018, has trained over 500,000 participants in IT skills. However, completion rates vary significantly (57%–96%), highlighting challenges in participant engagement and program effectiveness. This study integrates the DeLone and McLean Information Systems Success Model and the Technology Acceptance Model (TAM) to evaluate system effectiveness and user acceptance. Variables from the DeLone model—System Quality, Information Quality, and Service Quality—were incorporated into TAM constructs, influencing Perceived Ease of Use (PEOU), Perceived Usefulness (PU), and User Satisfaction, which shape Attitude Toward Use (ATU) and Behavioral Intention (BI). Survey data from 342 DTS administrators were analyzed using Structural Equation Modeling (SEM). Results show PEOU significantly influenced PU (path coefficient = 0.900) and ATU (0.594), while PU and ATU collectively explained 70.3% of BI. High PEOU (0.91) and PU (0.87) scores highlight the importance of system usability and utility. However, low ATU stems from organizational misalignment, as the system’s focus on participant quality contrasts with the DTS priority on participant numbers. Addressing this misalignment, enhancing system features, and improving service quality can boost adoption and foster a digitally skilled workforce aligned with Indonesia’s evolving demands.

link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5873
description: The study explores the relationship between digital literacy, exposure to AI-generated deepfake videos, and the ability to identify deepfakes by Generation X in Indonesia who are currently between the ages of 43 and 58. It also analyzes the impact of deepfake identification capabilities on the cognitive, affective, and behavioral aspects of internet users. Through a survey involving 199 respondents taken from a total population of 42 million Generation X internet users in Indonesia, it applied a random sampling method. The sample size was determined by the Slovin formula with a confidence level of 90% and a margin of error of 7.1%. The descriptive analysis shows a moderate level of digital literacy and relatively low exposure to deepfakes. However, the ability to identify deepfakes was found to be low. The results of inferential statistical analysis show that digital literacy and exposure to deepfakes do not have a significant influence on the ability to identify deepfakes. Additionally, the ability to identify deepfakes does not significantly affect cognition, compassion, or behavior. While digital literacy is important, these findings reinforce the assumptions of Generation Theory and Media Dependency Theory. Additionally, it suggests that specific training on media manipulation technologies is needed to improve deepfake detection capabilities. This research implies that efforts to improve digital literacy should be expanded, including technical skills and critical thinking relevant to manipulative media such as deepfakes.

link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5551
description: Network Security infrastructure including routers and server devices, which are connected directly to the global internet has become an important issue along with the increase in internet communications in maintaining the confidentiality, integrity and availability of digital communications. The most challenging problem is the network infrastructure for exploiting a monoculture of routers and servers and detecting Distributed Denial-of-Service (DDoS) attacks. This research aims to combine analysis and mitigation techniques with Hierarchical Clustering single linkage, complete linkage, average linkage and ward linkage as well as IPTables firewall filtering mitigation measures, to analyze DDoS logging data on NIDS suricata, with low, medium and high severity levels exploited from the network public. Clusteirng single linkage deployments produces cluster 3 with a DDoS logging intensity level of high severity, on the TCP Sync Flood protocol type. Cluster 3 shows high severity for the source IP address. The complete linkage clustering technique also provides significant results with a large number of potential DDoS logging, found in cluster 1 and cluster 2. The results of the average linkage distribution show a group with a low average severity level for DDoS. The Ward linkage clustering produces a more uniform group of attributes for each n_clusters 1 to cluster 6. Implementation of mitigation techniques with IPSet and firewall scripting IP Tables provides positive results in reducing the workload of router and vServer devices when facing DDoS attacks. After convergence, the running status resulted in the workload of vCPU resources experiencing a decrease in the percentage of vCPU vR1 by 10%, vCPU vR2 by 9% and memory by 11%.

link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5765
description: Electrical energy is one of the most important needs in the local area, concerning the provision of electrical power a transformer is needed to distribute electrical power to each house. The use of transformers in each area requires testing the oil content in them to assess the state of the transformer. The Duval Pentagon Method (DPM) and the Duval Triangle Method (DTM) can be used in tests to identify transformer interference. Owing to the vast quantity of transformers utilized in public energy distribution, the Adaboost machine learning method was applied to identify transformer disruptions. By categorizing test data on a dataset derived from tests conducted with the earlier DTM and DPM techniques, the AdaBoost algorithm predicts transformer disruptions. According to the findings of tests conducted using the best dataset, the division used 80% of the data for training and reserved 20% for testing, using a learning rate of 1 and an estimator of 400 for DTM. This resulted in an accuracy level of 91.1%, which is an excellent classification. In contrast, the DPM approach divides the dataset into 80% training and 20% testing, employs an estimator of 500, and has a learning rate of 0.5. This leads to an excellent classification accuracy rate of 84.9%.

Implementation of MTCNN Architecture on Different Pixel Dimension Classes and Plotting Multi-Face on Detection Results
type: item
link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5843
description: Face detection is a computer vision task to identify and verify a person based on a photo of their face. Face detection and alignment in unconstrained environments are very challenging due to various poses, illumination, and occlusions. The human face is difficult to model because there are many variables that can change, such as facial expression, orientation, lighting conditions, and partial occlusions, such as sunglasses, scarves, masks, and others. Recent studies have shown that deep learning approaches can achieve impressive performance on these two tasks. In this paper, face detection on multi-faces will be carried out as well as mapping one by one the results of the face detection obtained (face crop) for the needs of various systems related to face detection using the Multi-Task Cascaded Convolutional Neural Network (MTCNN) approach. This study aims to implement the MTCNN architecture using TensorFlow and OpenCV, with two main benefits. First, this study is expected to provide a pre-training model that performs optimally and strengthens evidence from previous studies that have examined this model. Second, this model can be used as input for other systems. The input variable is a photo image of a face containing one or more to be processed. This photo image will have various pixel dimensions to represent different resolutions. The output variable produced is in the form of coordinates of the detected face location or in the form of landmarks of key facial points, such as the position of the eyes, the corner of the nose, and the mouth. The results of the study showed an average score on various pixel dimensions in the dataset, with an accuracy of 93%, a precision of 95%, a recall of 96%, an F1-score of 95%, and an ROC-AUC of 90.89%.

description: This research investigates the impact of TikTok marketing strategies on brand image and purchasing decisions among Generation Z consumers in Indonesia, with a specific focus on the mediating role of product innovation. Utilizing a quantitative approach through an online survey spanning three months, the study collected data from diverse regions without geographical limitations. The sample consisted of 150 Generation Z consumers actively using TikTok and expressing interest in fashion products. Structural Equation Modeling (SEM) analysis using Amos software was employed for data analysis. The results revealed that TikTok marketing strategies significantly influence brand image, supporting Hypothesis 1. Similarly, product innovation has a significant positive effect on brand image, confirming Hypothesis 2. However, TikTok marketing strategies were found not to significantly impact purchasing decisions (Hypothesis 3 rejected), while product innovation significantly influences purchasing decisions among Generation Z consumers (Hypothesis 4 accepted). Additionally, brand image was identified as a significant factor affecting purchasing decisions (Hypothesis 5 accepted). The study concludes that a positive brand image is shaped by effective TikTok marketing and innovative product presentation, influencing the preferences of Generation Z consumers. Despite TikTok marketing's limited impact on purchasing decisions, product innovation plays a crucial role in shaping consumer choices. Practical implications for the fashion industry targeting Generation Z are discussed, emphasizing the need for integrated marketing strategies aligning with innovative product offerings.

type: item
link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5585
description: The Naïve Bayes (NB) algorithm is a classifier method that calculates simple probabilities and it is suitable for text classification in the context of sentiment analysis. The classic variant of NB is Multinomial Naïve Bayes (MNB). The weakness of the MNB algorithm is the assumption of feature independence. This research uses a dataset of comments and reviews from various online platforms. This study uses the proposed method to handle the weakness of the MNB algorithm, namely the use of TF-IDF feature extraction and N-grams (1-gram to 5-gram), and the use of Chi-Square feature selection, as well as handling dataset imbalance using SMOTE (oversampling and undersampling method). The results of this study show that the use of pentagram (5-gram) with data that has been oversampled by SMOTE produces the highest accuracy value of 94% and an Area Under Curve (AUC) value of 100%

type: item
link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5583
description: Support Vector Machine (SVM) is a supervised learning algorithm that works by classifying based on classes that refer to patterns resulting from the training process. SVM has several commonly and popularly used kernels, one of which is the linear kernel. The weakness of SVM is in the "parameter selection" and its performance tends to be poor in the case of unbalanced datasets. The purpose of this study is to overcome the weaknesses of the SVM algorithm with the proposed method. This research uses a linear kernel with feature extraction that is Word2Vec with Skip-gram model, and in handling the data imbalance problem using SMOTE (oversampling) technique. The results showed that the unbalanced dataset produced an accuracy of 90% and the balanced dataset (SMOTE) produced an accuracy of 92%, so the SMOTE oversampling technique was proven to increase the accuracy results by 2%.

Analysis of Geospatial-Based Road Milestone Clustering Using K-Means and Davies-Bouldin Evaluation
type: item
link: //jkd.komdigi.go.id/index.php/pekommas/article/view/5471
description: Geographic Information System (GIS) has become a very important tool for spatial analysis and decision making in various fields. In this paper, the analysis process of grouping Kilometer Hectometer (KM/HM) road milestones use the K-Means method in the context of GIS. The KM/HM road milestones are road equipment made of concrete or signboards equipped with texts containing information about the distance and the name of the city to be traveled by road users. The length of the road that has such a long distance will make it difficult to maintain and to manage the road milestones that are scattered throughout the road. Currently, the process of mapping the location of the road milestones is still being carried out using the conventional method, in which the survey officer records the data on paper and measures it with the vehicle's odometer. However, this method often causes data loss, errors in determining the location, and lacks photographic evidence as a reference for assessing the condition of the road milestones. The role of GIS for survey officers is to map the road milestones and to visualize the road milestone data. The main objective is to gain meaningful insights from the spatial distribution of these road milestones, which will assist in better navigation and infrastructure planning. The K-Means method separates clusters from KM/HM road milestones which are identified based on geographical proximity. To assess the quality of these clusters, the evaluation is conducted using the Davies-Bouldin index (DBI) which provides a quantitative measure of inter-group similarity and within-group dissimilarity. For officers, it can be useful to find location points for the road milestones that have high damage conditions to prioritize to be repaired first. Based on the test results using DBI, it produces a value close to zero, which is equal to 0.1656, indicating that the clusters formed have very good quality.
