Forecasting of Rice Agricultural Production in Lamongan Regency Using the Brown's Double Exponential Smoothing Method
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/5559
description: Rice production data from 14 sub-districts in Lamongan Regency during the 2008–2021 period, comprising 196 observations, exhibited variations over time. These fluctuations need to be anticipated because changes in rice production may affect rice availability. Therefore, a forecasting model is required to estimate rice production for the subsequent period as a basis for formulating agricultural and food security policies. The forecasting results can be utilized by the local government to plan rice reserve management, maintain price stability, optimize food distribution, and develop preventive measures in the event of a projected decline in production. This study applied the Brown Double Exponential Smoothing method to determine the smoothing parameter that produces the lowest forecasting error. Based on the evaluation of several alpha (α) values, α = 0.5 was identified as the optimal parameter, yielding the lowest Mean Absolute Percentage Error (MAPE) of 2.66%, indicating that the model has a relatively low forecasting error. Using this parameter, the forecasting model was obtained as: F_(t+m) = 791904.36 + 20071.34(m). The model was then used to forecast rice production in Lamongan Regency for 2022, resulting in an estimated production of 811,975.71 tons. In addition to evaluating the forecasting model, this study also assessed the developed system through questionnaire-based usability testing. The evaluation produced a feasibility score of 83.76%, which falls into the highly feasible category, indicating that the system is easy to learn, user-friendly, satisfying to use, and suitable for supporting decision-making in rice production planning.

Self-Disclosure in Managing the Mental Health of Generation Z Following Parental Divorce Through Anonymous TikTok Accounts
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6093
description: Parental divorce can affect Generation Z's mental health, emotional communication, and self-disclosure. Limited communication within post-divorce families encourages adolescents to seek alternative spaces to express their emotional experiences, one of which is through anonymous social media accounts. This study aims to understand the experiences of Generation Z individuals with divorced parents in utilizing anonymous TikTok accounts as a means of self-disclosure for mental health management through the perspective of Communication Privacy Management (CPM). This research employed a qualitative approach using Interpretative Phenomenological Analysis (IPA) involving four Generation Z participants who actively use anonymous TikTok accounts. The findings reveal that anonymous TikTok accounts serve as a space for expressing emotions, personal experiences, and psychological distress that are difficult to communicate directly. Self-disclosure practices function as a coping mechanism that helps participants achieve emotional release, while anonymity is utilized as a privacy management strategy that enables them to remain open without revealing their personal identities. These findings indicate that anonymous TikTok accounts enable Generation Z individuals with divorced parents to negotiate their need to express emotional experiences while maintaining control over their privacy in digital spaces.

Pertamina’s Crisis Communication Response Strategy in The Adulterated Fuel Case: A Quantitative Content Analysis of CNN Indonesia and Kompas.Com News
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6087
description: This study is motivated by a public trust crisis toward PT Pertamina following allegations of fuel adulteration from Pertalite to Pertamax. This incident triggered massive financial losses and a severe reputational threat. This research aims to describe Pertamina's crisis communication response strategy based on the Situational Crisis Communication Theory (SCCT) and analyze differences in tendency of implementing these strategies in CNN Indonesia and Kompas.com. The method used is quantitative content analysis with purposive sampling. The total sample includes 50 news articles (25 from CNN Indonesia, 25 from Kompas.com) during the peak crisis period of February-March 2025. Data were analyzed using descriptive statistics and the nonparametric Mann-Whitney U test. The results show a deviation from the ideal assumptions of SCCT. In a preventable crisis requiring a rebuild (accommodative) strategy, Pertamina predominantly used the Denial strategy at 60% (15 articles) in each media outlet. The Mann-Whitney U test yielded a significance value of 0.861 (Sig. > 0.05), thus the null hypothesis (H0) is accepted. In conclusion, there is no significant difference regarding the tendency of Pertamina’s crisis response strategies in both media. Both outlets uniformly display the dominance of Pertamina’s defensive communication approach (denial posture) in managing public perception.

Exploring Social Media Use through Uses and Gratifications Theory: A Systematic Literature Review
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6084
description: This research aims to analyze the application of the Uses and Gratifications Theory (U&G) in social media studies thru the systematic literature review (SLR) method with a PRISMA approach. A total of 21 journal articles published between 2022 and 2025 were analyzed to see how this theory is used. The research results show that U&G is still relevant in explaining social media user behavior, especially because it emphasizes that users are active in choosing media to meet specific needs. The research findings categorize gratifications into four main categories: motives-based, personal, social, and applied gratifications, which indicate the diverse purposes of social media use. Additionally, the types of gratifications are also influenced by the characteristics of each platform such as TikTok, Instagram, Facebook, LinkedIn, and X. However, existing research is still dominated by quantitative approaches, with limited geographical coverage and minimal use of mixed methods and studies related to the role of algorithms or new technologies. Therefore, future research is recommended to use a more diverse methodological approach and expand theoretical perspectives in order to understand the relationship between users and social media more comprehensively.

link: //journal.mmtc.ac.id/index.php/pekommas/article/view/5389
description: Stunting in toddlers represents a condition where isa nutritional deficiency. This becomes more complex when there is insufficient information regarding stunting in toddlers available. Predicting the prevalence of stunting in toddlers involves studying a dataset of stunting prevalence among toddlers through a supervised learning model using Support Vector Machine (SVM) and synthetic minority oversampling technique (SMOTE). The use of SMOTE serves as a data balancing method, while exploratory data analysis (EDA) acts as the preprocessing method for the toddler dataset. From the research implementation on a dataset consisting of 6879 toddlers, an accuracy of 94% was obtained for predictions. This accuracy is comprised of 94% accuracy, 95% precision, 94% recall, and a 94% F1-score.

title: Single Neuron PID Controller for Speed Regulation of Induction Motor on Gamma Irradiator Characterization Prototype and Its Comparison with Classical PID Controller Using the Modified Ziegler-Nichols Method
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6007
description: Induction motor control is a crucial part in the operation of gamma irradiator characterization prototypes, which are used for component testing and operator training. In this system, the induction motor functions as the primary actuator within the automated transport mechanism, therefore the motor's speed and stability greatly affect the accuracy of sample positioning relative to the radiation source. Proportional-Integral-Derivative (PID) controllers are widely used due to their simple structure but have limitations in responding to complex and time-varying system dynamics. To improve control performance, artificial intelligence-based control methods such as the Single Neuron PID (SNPID) have been developed as alternatives, offering adaptive characteristics through dynamic parameter adjustment. This study presents a comparative performance analysis between a PID controller tuned using the Modified Ziegler-Nichols (MZN) method and a SNPID controller in regulating the speed of an induction motor in a gamma irradiator system. Evaluation results show that the SNPID controller with a uniform learning rate of 0.5 and a Hebbian constant of 0.0018 produces faster, more stable, and more adaptive response compared to the MZN-tuned PID controller with a 30° phase margin. These results indicate that the SNPID controller is a more effective choice for motor control systems in gamma irradiation applications that require fast response, high precision, and robustness against disturbances.

Improving the Accuracy of Deep-Learning Models for Coconut Maturity Classification Using Acoustic Signals
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6004
description: Nowadays, the development of signal processing technology, advanced intelligent systems and deep learning have become commonplace in agricultural technology. One of the agricultural commodities that are widely available in the world is coconut. Unfortunately, the application of post-harvest agricultural technology is very minimal in coconut farming. So far, farmers have determined the maturity of coconuts by listening to the sound of the coconut being knocked so that it takes a lot of time to check the maturity level. This paper will discuss improving the accuracy of deep learning models in classifying coconuts based on acoustic signals. For the trial of the classification of the maturity level of coconuts, a deep learning method consisting of Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) was used. And using an open access dataset consisting of samples used of 129 coconuts with three classification levels - premature, mature and overmature (Caladcad, 2023). In this paper, we propose an improvement in the deep learning model architecture with learning rate parameters of 0.0001, epoch 500, Batch-Normalization and Dropout 0.3 with the results of the coconut acoustic signal classification test having a data testing accuracy of 98.36% and an F1 Score of 99%. The results of this trial are better than the previous trial (Caladcad, 2024) with an accuracy of 97.42% and an F1 Score of 97.20%. and shows that the improvement of the deep learning combination method produces a more reliable coconut ripeness classification system, and is free from class bias

Agency Visualization: Empowering Sexual Violence Survivors (A Feminist Study of Visual Rhetoric)
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/6015
description: News coverage of sexual violence on mainstream media portals often objectifies women as victims, both in the narrative and the visualization presented through supporting illustrations. Media that continuously objectify women will reinforce public perception in understanding the issue of sexual violence as detrimental to women as the majority of victims. To address this, Remotivi organized an illustration competition to challenge all creators taking their side with victims and survivors of sexual violence. This study aims to explore how illustrations can become a counter-narrative to those objectifying and visualizing women as the suffering ones. This study uses a descriptive qualitative method with feminist visual rhetoric analysis. The authors found that illustrations depicting their creators’ side with survivors of sexual violence display various elements we barely find on mainstream media: representation of empowered women as subjects, active gestures resisting perpetrators, a view point that comes from women as subjects, and things that cultivate a new perspective. It is expected that the new coming of illustrations using feminist perspective will change the public in understanding the issue of sexual violence in a deep and empathic way, no longer merely viewing victims as objects of news coverage.

description: This study examines the relationship between social media use by zoos in Bali, Indonesia, and tourist visits. The study investigates how effectively these platforms engage visitors and disseminate information by analyzing the official websites, Instagram accounts, and Twitter accounts of five zoos, combined with visitor surveys. The method used was to conduct a survey of visitors to tourist destinations. The survey results were processed using tools to determine the preferences of visitors to tourist destinations. The survey results showed that visitor preferences for communication channels differed between zoos, highlighting the importance of tailoring social media strategies to target audiences. By mapping visitor expectations against actual social media management practices, the study identifies areas for improvement and proposes a new framework for analyzing the effectiveness of digital communication media in parks and recreation. This framework allows zoo management to better align their social media strategies with visitor preferences, ultimately improving communication and potentially increasing tourist visits.

Applying the Analytical Hierarchy Process to Select Strategic Locations for Culinary MSMEs in Tomohon City
type: item
link: //journal.mmtc.ac.id/index.php/pekommas/article/view/5955
description: Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in Indonesia's economy, making up over 99% of business units. In Tomohon City, located in North Sulawesi, Indonesia, MSMEs, especially in the culinary sector, have faced challenges due to the COVID-19 pandemic, which led to significant revenue losses and business closures. However, recovery efforts are underway, prompting the development of a web-based system to aid culinary businesses in selecting optimal locations. Utilizing the Analytic Hierarchy Process (AHP) method, the system evaluates potential sites based on five criteria: completeness of infrastructure, population density, competition, community incomes, and business capital. Each criterion is assessed using sub-criteria such as very good to very inadequate, providing tailored recommendations for Downtown District, Dotu Tololui Tua Statue, Kakaskasen Highway Area, and Beriman Terminal. Among these criteria, infrastructure completeness (40.4%) is prioritized most, followed by population density (26.2%), competition (18.1%), community incomes (10.4%), and business capital (4.9%). The sensitivity analysis indicates that changes in criteria weights significantly impact the rankings of alternatives, with infrastructure and community incomes causing minor changes but preserving the top-ranked options, while population density and business capital lead to more substantial shifts, including changes in the top position.

type: item
link: //journal.mmtc.ac.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.

description: 5G and LoRa technologies have their own advantages in wireless communication. However, when used together, they can experience signal interference, especially at the 925 MHz frequency. This study aims to analyze interference between 5G and LoRa networks using the SEAMCAT simulation tool with a Monte Carlo approach. There are two scenarios used in this study, namely device spacing and transmit power settings. The simulation results show that the transmit power and device distance settings affect the Interference Received Signal Strength (iRSS) value and interference probability. At a distance of 35 km and a transmit power of 40 dBm, the interference probability is up to 0%. Thus the two technologies perform without interfering with each other. This research provides a simple solution to reduce interference and maximize the use of 5G and LoRa technologies in wireless communications

The Relationship of Digital Literacy, Exposure to AI-Generated Deepfake Videos, and the Ability to Identify Deepfakes in Generation X
type: item
link: //journal.mmtc.ac.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.

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%.

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: //journal.mmtc.ac.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%.
