Abstract

COVID-19 pandemic has changed human life. One of the impacted sectors is education. Ministry of Education urges students to implement distance learning. No exception with early childhood education or Pendidikan Anak Usia Dini (PAUD). Although distance learning has been widely implemented, PAUD sector has the lowest online learning implementation in Indonesia with 13.2% of total 98.4% of PAUD students implementing distance learning, whereas early age is considered capable of gaining an understanding of digital technology and equipment. One possible step in conducting digital learning in PAUD is through a digital educational game, because game is an important element in PAUD. In this study, a digital educational game was developed for TK-A level students using Scratch 3 with multimedia development life cycle method. After development, the game goes through two stages of testing. Alpha testing in the form of black box testing, and beta testing in the form of usability testing with 94,39% result, confidence testing with 97,8% result, and summative evaluation with 90% result on TK-A students, as well as interviews with PAUD teachers. The test results indicate that the game has been successfully developed and is feasible to be played by TK-A students.

Abstract

The presence of haze in an image is one of the challenges in computer vision tasks, such as remote sensing, object monitoring, and traffic monitoring applications. The hazy image is considered to contain noise and it can interfere with the image analysis process. Thus, image dehazing becomes a necessity as part of image enhancement. Dark channel prior (DCP) is one of the images dehazing methods that works based on a physical degradation model and utilizes low-intensity values from outdoor image characteristics. The DCP method generally consists of some steps, which are finding the dark channel and gradient image, estimating the sky region, atmospherical light, and transmission map, and reconstructing the dehazed image. This study introduces image dehazing by utilizing the Gaussian filter combined with the DCP method to increase the sharpness and accentuate the details of hazy images. Experimental results show that the proposed method could produce dehazed images with a visual quality is 18.94 dB on average or an increase of 11.91% compared to the original hazy image with a similarity index is 66.71% on average or an increase of 8.10%. Therefore, it is expected that this study can contribute to the image dehazing method enrichment based on DCP.

Abstract

Dalam beberapa penelitian terdahulu, proses pembobotan kriteria belum menjadi perhatian penting karena masih didasarkan pada hasil wawancara secara subjektif dan belum dihitung secara matematis. Pembobotan kriteria dalam sistem pendukung keputusan kelompok merupakan salah satu proses awal yang dilakukan sebelum mengambil sebuah keputusan, proses ini penting dilakukan untuk memastikan bahwa bobot kriteria yang digunakan sesuai dengan kebutuhan. Dalam penelitian ini, proses pembobotan kriteria dihitung secara matematis dengan best worst method. Untuk dapat membangun sistem pendukung keputusan kelompok yang bisa membantu Dinas Sosial dalam menentukan calon penerima bantuan, metode best worst method digabungkan dengan metode MOORA dan copeland score. Best worst method dipilih karena hasil pembobotan yang diperoleh lebih konsisten serta mudah dalam membandingkan kriteria. Metode MOORA memiliki perhitungan matematis lebih simpel dan hasil yang stabil. Dan metode copeland score memiliki keunggulan efektif sebagai alat dalam sistem voting. Penggabungan metode yang dilakukan, lalu diujikan pada studi kasus penentuan calon penerima bantuan. Untuk menentukan penerima bantuan, ada tiga pengambil keputusan yaitu sektor kesehatan, sektor pendidikan dan sektor sosial yang dilibatkan dalam menentukan peringkat akhir dari masing-masing calon penerima bantuan. Hasil perhitungan menunjukkan bahwa alternatif 2 memiliki skor tertinggi dibandingkan alternatif lainnya dengan nilai akhir 4. Analisis sensitivitas menunjukkan konsep sistem pendukung keputusan dengan penggabungan metode yang diusulkan solid, dengan persentase perubahan rendah yaitu 23,52%. Hasil perhitungan dengan metode ini dapat dijadikan sebagai acuan dalam proses pengambilan keputusan bagi Dinas Sosial, sebab ketepatan pilihan penerima bantuan sosial memiliki pengaruh langsung terhadap pencapaian tujuan perlindungan sosial. AbstractIn several previous studies, the process of weighting criteria has not become an important concern because it is still based on subjective interview results and hasn’t been calculated mathematically. One of the initial procedures in a GDSS before reaching a choice is the weighing of the criteria, this process is crucial to ensure that the weighting of the criteria utilized is appropriate for the demands. The weighting of the criteria in this study is computed quantitatively using the best worst method. Best worst method, MOORA, and copeland score are combined in order to create a GDSS that will help the Office of Social Affairs identify probable beneficiaries. Best worst method was chosen because the weighting results obtained are more consistent and easier to compare criteria. MOORA method has simpler mathematical calculations and stable results. And copeland score method has an effective advantage as a tool in the voting system. The combined methods were then evaluated in a case study involving the identification of aid recipients. The health sector, the education sector, and the social sector are the three decision-makers who establish the ultimate ranking of each potential beneficiary in order to determine recipients. The calculation results show that alternative 2 has the highest score compared to the other alternatives with a final score of 4. The sensitivity analysis shows that the concept of a GDSS by combining the proposed methods is solid, with a low percentage change of 23.52%. The precision of the selection of social assistance beneficiaries has a direct impact on the achievement of social protection goals, so the results of calculations using this method can be used as a reference in the Social Service's decision-making process.

Abstract

Purpose: To evaluate the governance of the LaporGub Central Java service portal information system using the COBIT 2019 framework to obtain a comprehensive overview of the implemented capability levels. Methods: This study employs a qualitative method using the COBIT 2019 framework to assess capability levels, which is further combined with CMMI to provide improvement recommendations. The method produces valid and accurate results as respondents are selected using the RACI model, and the assessment is conducted at the subdomain level. Consequently, each domain yields valid outcomes, enabling precise and well-targeted recommendations. Results: This study successfully determined the level of LaporGub service capability using COBIT 2019 and showed that most domains have achieved, and in some cases even exceeded, the set targets. However, several areas still require improvement, especially in services security and business process control, as well as problem management. These findings indicate that the Central Java Provincial Communication and Information Office has a strong foundation in operational management and service sustainability. With proper improvements in IT governance, LaporGub is expected to serve as a model for adaptive and accountable digital public services that can be replicated in other regions across Indonesia. Novelty: This study introduces innovation by integrating COBIT 2019 with CMMI, an uncommon combination in capability level assessments within government institutions. Innovative techniques such as text development, respondent questionnaires based on the RACI model, and interviews are used to avoid redundancy in the research findings. By utilizing questionnaires, interviews, and document reviews, this approach enhances the validity of the study results.

Abstract

Purpose: The research aims to determine the factors that encourage users to upgrade service packages, provide actual recommendations for application developers to improve service quality, and provide insights for the development of similar applications in the future. Future Link is an application that offers efficient online fingerprint analysis with the support of artificial intelligence (AI). Despite these advantages, user acceptance and satisfaction remain challenges that hinder service package upgrades. Methods: This study combines the TAM and EUCS models to identify the variables that influence users' intentions to upgrade their service packages in a fingerprint analysis application. TAM includes key constructs such as perceived usefulness and attitude toward using, while EUCS encompasses dimensions like content, accuracy, format, timeliness, and ease of use, which collectively represent users’ satisfaction with the quality of information provided by the application. Additionally, two external variables curiosity and buying intention were added. A quantitative approach was employed using a survey method, with data collected from 151 respondents who are active users of the application. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) through Smart-PLS 3.29. The analysis process included instrument development based on validated indicators, testing for construct reliability and validity, followed by evaluation of the structural model to assess the significance and explanatory power of the hypothesized relationships among variables. Result: The findings show that eight out of nine hypotheses were accepted. Significant variables influencing attitude toward use include curiosity, content, format, accuracy, perceived usefulness, and ease of use. User attitude significantly influences satisfaction, which in turn impacts service package upgrade intentions. Novelty: The combination of two theoretical models the TAM and EUCS model is used to analyze user behavior in the context of service package upgrades in fingerprint analysis applications. While previous studies have applied TAM and EUCS separately to evaluate general technology adoption or information satisfaction, this study integrates both models to provide a more comprehensive framework that considers both perceptual and experiential factors influencing user decisions. Furthermore, this study introduces two additional variables curiosity and purchase intention to reflect emerging user motivations in the use of digital services. The results are expected to support the development and improvement of applications in the future.
