The Effect of Compensation and Work Motivation on Teacher Job Satisfaction at Elementary Schools in Kahala Village, Kutai Kartanegara Regency
type: item
description: Teacher job satisfaction is an important factor that influences the quality of learning and the achievement of educational goals. Compensation and work motivation are factors that can affect teachers’ perceptions and attitudes toward their jobs. Appropriate compensation and high work motivation are expected to encourage teachers to perform their duties optimally and enhance their level of job satisfaction. This study aims to analyze the effect of compensation and work motivation on teacher job satisfaction at elementary schools in Kahala Village, Kutai Kartanegara Regency. This study employed a quantitative approach. Data were collected through questionnaires distributed to all 36 teachers using a saturated sampling technique. The data were analyzed using multiple linear regression with the assistance of Statistical Product and Service Solutions (SPSS). The results indicate that compensation does not have a significant effect on teacher job satisfaction. In contrast, work motivation has a positive and significant effect on teacher job satisfaction. Simultaneously, compensation and work motivation have a significant effect on teacher job satisfaction. The findings reveal that teacher job satisfaction is influenced not only by financial rewards but also by motivational factors that enhance enthusiasm, commitment, responsibility, and dedication in carrying out teaching duties. These findings highlight the important role of work motivation in creating a supportive work environment that contributes to improved teacher performance and job satisfaction. Therefore, schools and relevant stakeholders should strengthen teachers’ work motivation through recognition, supportive working conditions, and professional development opportunities to improve job satisfaction and enhance the quality of education.

type: item
description: Household and plastic waste remain major challenges in environmental management in Indonesia, including in Samarinda City. One of the efforts to reduce waste volume while providing economic benefits to the community is through the RAMLI Sidodadi Waste Bank. However, data management and transaction recording at the waste bank are still carried out manually using passbooks, which may lead to recording errors, data loss, and inefficient customer services. Therefore, a technology-based solution is needed to improve the effectiveness and transparency of waste bank management. This study aims to develop an Android-based RAMLI Waste Bank application for Samarinda City that can facilitate data management and information access for both customers and administrators. The research employed a descriptive approach, with data collection techniques including literature studies, interviews, and observations. The system was developed using the Waterfall method, which consists of requirements analysis, system design, implementation, testing, and maintenance stages. The application was built using the Flutter framework, Dart programming language, and Firebase Realtime Database as the data storage platform. The application provides several features, including user login and registration, waste type information, waste bank location services, waste management educational content, point balance checking, transaction history, and user profile management. The development results indicate that the application improves transaction recording efficiency, facilitates real-time access to information, enhances data transparency, and reduces the risk of data loss. Therefore, the Android-based RAMLI Waste Bank application can serve as a digital solution that supports sustainable waste management while increasing community participation in environmental conservation and generating economic benefits through waste management activities.

Effectiveness Analysis of DHCP Snooping and Port Security Against DHCP Starvation Attacks on Cisco-based VLAN Networks
type: item
description: Traditional Dynamic Host Configuration Protocol (DHCP) protocols implemented on Virtual Local Area Network (VLAN) networks are highly vulnerable to DHCP Starvation attacks due to the absence of device authentication mechanisms. This research aims to comparatively analyze the effectiveness level of DHCP Snooping and Port Security features on Cisco switches in maintaining the availability of IP Address allocation services. The research method was conducted experimentally through a multi-tiered network infrastructure simulation using Cisco Packet Tracer simulator. The testing evaluated two main scenarios: operational conditions without security and conditions with an active protection system. The measured testing parameters included the IP request packet rate (configured at a DHCP Snooping Limit Rate of 2 packets per second), the maximum number of MAC Addresses per physical port (configured for 1 address via Port Security), and the network disruption response time. The testing results indicated that in the unsecured scenario, the attack successfully exhausted 100% of the address pool allocation (254 IP Addresses) within 3 to 5 seconds, causing total service downtime for all legitimate users. Conversely, when the active protection system with a shutdown violation parameter was applied, the switch instantly isolated the attacker's physical port into an err-disable status in less than 1 second after detecting a violation. The research conclusion proves that the combination of these two features has a 100% effectiveness rate in maintaining addressing stability and protecting the integrity of VLAN network infrastructure from disruption.

Evaluation of Konselopoly Quest as Educational Media in Riverside Schools Through the CIPP Model
type: item
description: This study purpose to evaluate the implementation of Konselopoly Quest as an educational medium in riverside schools using the Context, Input, Process, and Product (CIPP) evaluation model. A qualitative approach was employed involving students from SMA Negeri 12 Banjarmasin selected through purposive sampling. Data were collected through in-depth interviews, observations, and documentation and analyzed using the Miles and Huberman interactive model, which includes data reduction, data display, and conclusion drawing. The findings indicate that, in the context dimension, the game successfully created a more engaging and interactive learning environment, although the content was not fully aligned with students’ academic needs. In the input dimension, the visual design and overall appearance were perceived positively, while the use of foreign terms and game mechanics required further simplification. In the process dimension, the game enhanced students’ social interaction, teamwork, participation, and critical thinking skills, despite uneven levels of involvement influenced by group dynamics. In the product dimension, the game contributed positively to students’ understanding of Pancasila Student Profile values, social skills, and self-confidence. However, its impact on long-term learning motivation and comprehensive understanding of wetland environments remained limited. Overall, Konselopoly Quest was found to be a reasonably effective educational medium that promotes active, communicative, and enjoyable learning experiences, although improvements are still needed in terms of content, language, game mechanics, and implementation strategies.

Ethical Violations and Their Effects on Public Accounting Firms:A Case Study of KAP XYZ
type: item
description: Ethical violations by external auditors may reduce audit quality and create risks of inappropriate audit opinions, particularly when audited financial statements are used by external parties such as creditors. This study was to analyze the process, causes, and effects of ethical violations in an anonymized audit engagement at KAP XYZ involving Bank X. The study used a qualitative retrospective case study approach. Data were collected through semi-structured interviews with two actual informants, namely a partner familiar with the accountability process and a junior auditor who participated in fieldwork, supported by document review, member checking, and source triangulation. The data were analyzed thematically by comparing interview codes with the Indonesian Public Accountant Professional Code of Ethics and relevant Standards on Auditing. The findings indicate violations of professional competence and due care in audit planning, fieldwork, and reporting. Inventory and receivables testing relied excessively on analytical procedures without sufficient alternative procedures. Time pressure, weak supervision, and limited audit evidence contributed to an inappropriate unmodified opinion. The case resulted in contract termination by Bank X, reputational damage, and restrictions on the responsible auditors.

Analysis of Food Security Index in East Kalimantan Using Panel Regression and K-Means Clustering
type: item
description: This study aims to identify indicators that significantly influence the Food Security Index (IKP) of districts/cities in East Kalimantan Province and to group regions based on their food security characteristics. Food security is a crucial issue because it relates to the availability, accessibility, and utilization of food, which are influenced by socioeconomic conditions, education, health, and basic infrastructure. Differences in characteristics between regions in East Kalimantan encourage the need for analysis that can explain the influence of variables both spatially and temporally. The methods used in this study are panel data regression and K-Means Clustering. Panel data regression is applied to analyze variables that significantly influence the IKP, while the selection of the best model is carried out through the Chow Test, Hausman Test, and Lagrange Multiplier Test. Furthermore, the K-Means Clustering method is used to group districts/cities based on food security indicators. The results show that the best model is the Common Effect Model (CEM) with a coefficient of determination of 91.7%. Variables proven to significantly influence the IKP include rice production, poverty rate, per capita expenditure, electricity access, average length of schooling, life expectancy, and access to safe drinking water. Furthermore, the results of the K-Means Clustering analysis yielded three regional groups with distinct food security characteristics, which can serve as a basis for formulating more targeted food security policies in East Kalimantan.

Gandrung Sewu Festival as a Sustainable Tourism Attraction in Banyuwangi, East Java
type: item
description: Gandrung Sewu Festival has enriched the Banyuwangi Festival series and is recognized as part of the Karisma Event Nusantara (KEN). First held in 2012, this cultural event offers more than a traditional performance; it provides educational value for tourists through a unique and modern presentation. The festival also generates positive impacts on the local community, particularly through the active participation of Banyuwangi’s younger generation in its implementation. However, several aspects still require evaluation, both internally and externally. This study aims to formulate strategies to sustain the existence of the Gandrung Sewu Festival as a sustainable tourism attraction in Banyuwangi, East Java. The research applies a quantitative descriptive method using the Internal-External (IE) Matrix as the analytical tool. The results show that the festival’s strengths include the Gandrung dance as its core identity, strong community participation, creative annual themes, and the growth of Banyuwangi’s tourism sector. The main internal strength is its strategic location, while the key weakness is the inconsistent scheduling of the event. Externally, the greatest opportunity lies in tourism sector development, while the main threat comes from natural disasters and weather conditions. This study proposes three strategic recommendations to strengthen the festival’s sustainability. The findings are expected to serve as a reference for developing event-based sustainable tourism attractions in Indonesia.

The analysis process was carried out through several stages, namely stationary testing using the Augmented Dickey-Fuller (ADF) method, model identification through Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF), parameter estimation, diagnostic tests, and forecasting processes. The results showed that the best model obtained was ARIMA (0,1,0) after first-order differentiation. The model produces residual that meets the assumption of white noise and is normally distributed. The forecast results show a tendency to decrease the number of new students in the 2026–2028 period. The model evaluation showed a very good level of accuracy in the Informatics Engineering Study Program with a Mean Absolute Percentage Error (MAPE) value of 9.64% and quite good in the Information Systems Study Program of 24.88%. Thus, the ARIMA model (0,1,0) is considered effective in supporting the planning of new student admissions in a more measurable and systematic manner.

Cigarette Sales Forecasting at Bali Jaya Store Using the Single Method Exponential Smoothing
type: item
description: This study aims to forecast cigarette sales at Toko Bali Jaya using the Single Exponential Smoothing method as a quantitative approach to support more effective inventory management. The problems faced are the unstructured sales recording process and the manual determination of stock levels, which leads to inaccuracy in inventory control and potentially leads to overstocking or understocking. The Single Exponential Smoothing method was chosen because it is known to be effective in forecasting time series with fluctuating data patterns and no significant trends. The data used are cigarette sales data for 12 months which are processed to produce forecast values for the following period. The accuracy evaluation process is carried out using the Mean Absolute Percentage Error (MAPE) as an indicator of the level of forecast error. The results show that the best smoothing constant value is obtained at α = 0.3 with a MAPE value of 5.93%. This value indicates a low error rate, so the method used is able to produce forecasts that are close to the actual data. Thus, this method can be used as a basis for decision-making related to cigarette inventory management in a more systematic and measurable manner.

Recruitment of Civil Servants Following The State of Emergency at The Sawang Subdisdrict Office, North Aceh Regency
type: item
description: This study aims to determine the recruitment process of civil servants and its impact on professionalism and transparency at the Sawang Sub-District Office in North Aceh Regency. The method used in this study is descriptive qualitative, with data collection techniques including interviews, observation, and documentation. The data obtained was then analyzed through data reduction, data presentation, and data verification. The results of the study show that the recruitment of civil servants after the military emergency at the Sawang Subdistrict Office was simple, quick, and tended to be closed because it was more influenced by the need to maintain socio-political stability, reconciliation, and the continuity of government in a post-conflict situation than by the strict application of merit principles, so that the process did not involve open selection or competency tests. This situation has impacted the professionalism of the State Civil Apparatus, which is not yet optimal, as well as low levels of transparency, because the recruitment process is based more on social and situational considerations during the transition period. When compared to the principle of meritocracy, this recruitment practice is not entirely appropriate because it does not place qualifications, competence, potential, performance, and integrity as the main criteria, even though it can be understood as an adaptive policy by local governments to maintain peace and ensure that public services continue to run.

type: item
description: This study aims to determine how the effectiveness, accessibility, and ease of service affect customer satisfaction with the BYOND by BSI application at BSI KCP Gandapura. This study was motivated by the author's observation that the usage rate of the BYOND by BSI application among KCP Gandapura customers is still low, as reflected in the perception that BYOND is not yet able to provide a better service experience than BSI Mobile. Customers are also reluctant to switch because the BYOND application is considered ineffective, often experiences technical problems, is difficult to access at certain times, and has a display and features that are not yet fully user-friendly. This study used a quantitative method, where the data source used was primary data obtained by distributing questionnaires to Gandapura KCP customers who were BYOND by BSI users. The data analysis technique used was multiple linear regression analysis using SPSS software. The results showed that the effectiveness, accessibility, and ease of service partially had a positive and significant effect on customer satisfaction with the BYOND by BSI application at KCP Gandapura. Then, the simultaneous test results showed that effectiveness, accessibility, and ease of service also had a significant effect on customer satisfaction with the BYOND by BSI application at KCP Gandapura.

Classification of Avocado Ripeness Levels Using Transfer Learning Based on VGG16 and VGG19
type: item
description: The determination of avocado ripeness is still commonly performed manually, which is subjective and often inaccurate due to its reliance on human visual perception. Traditional methods, such as pressing the fruit surface, may damage avocado quality and are inefficient for large-scale distribution and marketing. This study aims to automatically classify avocado ripeness levels using a deep learning approach based on transfer learning. The proposed method employs transfer learning using Convolutional Neural Network architectures, namely VGG16 and VGG19, which have been pre-trained on the ImageNet dataset. The research stages include image pre-processing such as resizing, normalization, and data augmentation to enhance input quality. Subsequently, model training and testing are conducted by comparing the performance of both architectures using evaluation metrics. The dataset used in this study is obtained from the Kaggle platform and consists of avocado images with various ripeness levels. Experimental results indicate that both models are capable of classifying avocado ripeness with high accuracy, precision, recall, and F1-score, with the VGG19 model achieving the best performance. These findings demonstrate that the deep learning approach effectively addresses the subjectivity and inaccuracy associated with manual avocado ripeness determination. This study contributes to the development of an accurate, objective, and practical image-based avocado ripeness classification system with potential applications in agriculture and fruit distribution

Sentiment Analysis of Public Comments on YouTube Content Using Principal Component Analysis and Naive Bayes
type: item
description: The rapid acceleration of digital media development compels public broadcasting institutions to adapt to shifting public information consumption patterns, which are now centered on online platforms. TVRI Sumatera Barat has responded to these dynamics by leveraging YouTube as a channel for content distribution and audience engagement. However, this interaction generates a massive volume of unstructured comment text, rendering manual sentiment analysis inefficient, time-consuming, and prone to subjectivity. This study aims to address these challenges by automatically and objectively classifying user sentiment using a machine learning approach. The applied methodology integrates Principal Component Analysis (PCA) and the Gaussian Naive Bayes algorithm. PCA serves as a dimensionality reduction technique to simplify TF-IDF weighted text features without losing vital information, while Gaussian Naive Bayes was selected for classification due to its efficiency in rapidly processing the continuous numerical data resulting from the PCA transformation. The research dataset comprises 10 comments from the TVRI Sumatera Barat YouTube channel in 2024, collected via the YouTube Data API, which underwent preprocessing and labeling for positive and negative sentiments. Model validation was conducted using a confusion matrix with accuracy, precision, recall, and F1-score metrics. The test results demonstrate that the combination of PCA and Gaussian Naive Bayes effectively enhances computational efficiency and delivers precise classification performance. This research makes a significant contribution by providing a measurable method for public opinion analysis, which is essential as a basis for evaluating audience perception to improve the quality of digital broadcasting strategies in public institutions.

type: item
description: Infectious diseases in children remain a serious health problem due to their high vulnerability resulting from an immune system that is not yet fully developed. Limited access to medical personnel and delays in early detection often result in ineffective treatment. Therefore, this study aims to design and implement an Android-based intelligent system application capable of detecting infectious diseases in children early on by utilizing the Certainty Factor and Naïve Bayes methods. This system is designed as an expert system that mimics the way pediatricians analyze symptoms and determine preliminary diagnoses. The research methods used include collecting disease and symptom data based on the knowledge of pediatric health experts, data analysis, rule base formation, and the design and implementation of an Android-based system. The Certainty Factor method is used to handle the uncertainty of the level of confidence in the symptoms selected by the user, while the Naïve Bayes method is used to calculate the probability of disease based on historical data. The combination of these two methods aims to improve the accuracy and reliability of diagnostic results. The results of the study show that the developed expert system application is capable of providing initial diagnostic information on infectious diseases in children quickly and easily accessible to parents and health workers. This system is expected to be an effective early detection tool, support initial medical decision-making, and contribute to the development of artificial intelligence-based health technology in Indonesia.

Teacher Performance Evaluation Analysis Using K-Means Clustering Algorithm and Random Forest Classification
type: item
description: Teacher performance assessment is a primary parameter in determining the quality of educational institutions. Evaluation systems in many elementary schools still rely on descriptive qualitative approaches. Abundant school administrative data often remain as unprocessed archival records without further analytical utilization. This condition results in school management decision-making that lacks a strong empirical foundation. This study applies data mining technology to transform administrative data into strategic information. The research focuses on SD Negeri 12 Padang Besi and involves all active teaching staff during the current academic year. The research dataset is entirely derived from internal school records. This study excludes the use of questionnaire instruments, and in-depth interview methods are not employed in the data collection process. The analysis is strictly limited to administrative aspects, without including assessments of in-class pedagogical competence. The technical implementation utilizes the K-Means Clustering algorithm to automatically identify patterns in teacher performance grouping. This process is followed by the application of the Random Forest algorithm to measure classification accuracy based on the available administrative features. The combination of these methods produces a performance mapping that is free from human subjectivity. The analytical results provide clear performance labels for each individual teacher. This study contributes to the development of a data-driven digital evaluation model. School management can use the outputs of this research as a basis for reward allocation or targeted professional development programs. This approach ensures transparency in human resource governance within the educational environment.

Deep Learning Analysis for Predicting the Approval Time of Clinical Practice Guidelines (CPG) Based on Historical Administrative Data
type: item
description: This study aims to predict the processing time of the approval of Clinical Practice Guidelines (CPG), which exhibits considerable variation in duration and is difficult to predict accurately. In addition, the utilization of historical hospital administrative data to build effective predictive models for estimating the duration of the CPG approval process has not yet been optimized. Therefore, this research seeks to develop a predictive model to estimate the processing time of the CPG approval process.The proposed approach employs deep learning techniques by leveraging historical administrative data as the basis for modeling. The methods applied include K-Means Clustering, Decision Tree, and Long Short-Term Memory (LSTM). K-Means Clustering is used to group CPG data based on similar administrative characteristics, enabling the identification of approval time patterns. Subsequently, the Decision Tree method is utilized to analyze the relationships among variables and to generate classification rules that explain the factors influencing the duration of the CPG approval process. Meanwhile, LSTM serves as the primary model for predicting the processing time of CPG approval.This study uses 487 CPG records collected over the period from 2020 to 2024. The evaluation results indicate that the K-Means Clustering method achieves an accuracy rate of 87,36%. This level of accuracy reflects strong clustering performance and a high degree of conformity with actual conditions, indicating that the results are suitable to be used as a foundation for further analysis in the classification and prediction stages of the CPG approval process.

COBIT as a Framework for Evaluating Strategic Business IT Alignment:Systematic Literature Review
type: item
description: Strategic business IT alignment is a critical factor in the success of organizational IT governance. Numerous studies have examined the use of COBIT in the context of IT governance and business IT alignment across various sectors. These studies are generally partial and limited to specific contexts or COBIT domains, resulting in a lack of a comprehensive understanding of cross sectoral patterns in the use of COBIT and the evaluation approaches applied. This literature review aims to map the use of COBIT as a framework for evaluating IT business alignment across different sectors, including the COBIT domains and evaluation approaches employed. This study adopts a Systematic Literature Review (SLR) approach following the PRISMA guidelines, which consist of identification, screening, and final selection stages. The review results indicate that COBIT implementation is distributed across four sectors, namely education (35,29%), industry (29,41%), government and healthcare (each 17,65%), with the education sector being dominant context. The APO domain is the frequently used domain, followed by EDM, DSS, BAI, and MEA. Collectively, these domains reflect an evaluation focus on strategic planning, resource management, risk management, IT service delivery, and monitoring and evaluation mechanisms. The evaluation approaches identified in the reviewed literature are predominantly assessment-based, followed by IT governance design approaches, while comparative and exploratory approaches are used in a limited number of studies. The results of this review contribute by providing a structured overview of the patterns of COBIT domain usage and evaluative approaches across sectors. These findings may serve as a reference for future research as well as for practical evaluations of business and IT strategic alignment.
