Abstract

Pada era saat ini hampir semua kegiatan tidak terkecuali bidang pendidikan sudah menerapkan penggunaan teknologi dalam menjalankan kegiatan pembelajaran. Yayasan Islam Nurus Sunnah yang terletak di Kelurahan Bulusan Kecamatan Tembalang Kota Semarang belum menerapkan teknologi informasi untuk sistem penilaian guru. Permasalah utama yang ada Yayasan Nurus Sunnah ini adalah melakukan penilaian guru mitra masih dilakukan secara manual sehingga mengalami beberapa kendala. Kendala yang dihadapi yaitu data yang tidak terintegrasi, kurangnya aksesibilitas terhadap data, proses penilaian yang tidak fleksibel dan keamanan data yang kurang terjamin. Alternatif solusi yang akan diterapkan pada mitra tersebut adalah menyediakan sistem online berbasis web untuk proses penilaian kinerja guru. Proses digitalisai penilaian guru diharapkan dapat mengintegrasikan data dan mempermudah proses penilaian guru. Kegiatan ini terdiri dari empat tahapan, tahapan pertama adalah identifikasi kebutuhan untuk kegiatan observasi lapangan, diskusi dengan mitra, dan analisis situasi untuk menetapkan permasalahan yang dihadapi mitra. Tahapan  kedua adalah perencanan dilakukan dengan proses desain aplikasi dan database aplikasi online berbasis web serta pembuatan aplikasi web dan database. Tahapan ketiga digunakan untuk pelatihan SDM agar terampil dalam mengoperasikan sistem aplikasi berbasis web dan sekaligus dilakukan uji coba (trial and error) penerapan dan koreksi sistem aplikasi web. Tahapan keempat adalah evaluasi terkait kerja sistem. Impelementasi hasil kegiatan menunjukkan meningkatkan performansi kegiatan penilaian guru yang dilakukan setiap periode menjadi lebih cepat dan akurat. Mitra mendapatkan dampak positif dengan diterapkannya sistem digitalisasi sistem penilaian guru. Solusi ini yang diberikan terbukti bisa efektif untuk membantu dalam manajemen penilaian guru pada mitra.   Nowadays, almost all educational activities are conducted online unless the field of education has already adopted the use of technology in teaching. The Nurus Sunnah of Islam that is practiced in the Kelurahan Bulusan Kecamatan Tembalang Kota Semarang does not use information technology for its guru certification system. The primary problem with this Yayasan Nurus Sunnah is that the mitra penilaian is mostly done manually, resulting in a few kendals. The data that is being handled include incomplete data, inconsistent data accessibility, non-flexible data processing procedures, and inconsistent data quality. Offering these partners a web-based online system for the teacher performance assessment procedure is an alternate approach that will be used. It is anticipated that the digitization process for teacher assessments will facilitate data integration and streamline the process. There are four stages to this activity. The first is determining the need for field observation exercises, partner discussions, and situation analysis to ascertain the issues that partners are facing. The creation of web applications and databases, along with the application design process and web-based online application database, comprise the second stage of planning. In the third stage, HR personnel receive training on how to effectively operate web-based application systems and conduct trial-and-error procedures for the purpose of implementing and optimizing web application systems. The assessment of the system's functionality is the fourth step. The application of the activity results demonstrates that there has been an increase in the speed and accuracy of the teacher assessment tasks completed each period. Partners' implementation of the teacher assessment system's digitalization has produced positive results. It has been demonstrated that this solution works well to help partners manage teacher assessments.

Abstract

The process of making salt is still done manually by filling water into reservoirs and plots which require salt farmers to visit their farms periodically. This is mainly because the speed of the salt crystalization process is always inconsistent due to salt concentration in seawater and the weather. This study aims to build a new prototype of a water level monitoring system in reservoirs and plots in salt ponds then measure the water's salinity value, which will be reported to the farmers. The method used in this research is prototyping, which includes system requirement analysis, rapid design, prototype building, system evaluation, and system  improvement. The system was tested using the black box method, namely testing all system functionality and determining user satisfaction with questionnaires. The functionality test results, including monitoring the water level and the pump control, show that the prototype functions correctly. The designed system can send information in the form of water level values in reservoirs, water levels in plots, and salinity values with linear sensor accuracy with measurement results with conventional measuring instruments with standard error values of 0.485, 0.44, and 0.72, respectively. Applying this system will ease farmers’ monitoring of water levels and controlling irrigation in reservoirs and plots.

Abstract

These instructions Abstract - However, determining the ripeness of fruit is frequently done by hand, which presents problems with consistency and efficiency. In order to improve the sorting of crystal guava fruit maturity, this study suggests combining machine learning technology with the creation of digital image-based apps. Fruit ripeness is classified using a convolutional neural network (CNN), a deep learning model, based on the color of its skin. It is anticipated that the method will increase productivity and offer superior precision while sorting crystal guava fruit. The System Development Life Cycle (SDLC) with a Waterfall approach is the methodology employed. The system design formed from the deep learning model resulted in excellent performance in classifying images of crystal guava fruit by utilizing model training from the base models ResNet50V2, DenseNet121, NASNetMobile, and MobileNetV2 with a combination of training using K-fold cross-validation with a 5-fold configuration. The best-trained model achieved an average highest accuracy of 99.92% in model training using MobileNetV2 with the lowest average loss value of 0.0088. The system application was developed using mobile Android, leveraging the Flutter framework and Dart programming language. The research results demonstrate a comparison of testing on crystal guava and local guava fruits against ripeness classification parameters

Abstract

This study explores a digital transformation initiative implemented for UMKM Bakat Jaya, a micro-enterprise based in Magelang specializing in animal feed production. Initially hindered by limited market reach, low digital literacy, and a lack of integrated technological tools, the enterprise relied primarily on traditional social media platforms for promotion. To address these challenges, a comprehensive and user-friendly website was developed using WordPress, featuring a professional company profile, product gallery, contact information, and seamless integration with existing social media accounts. The project was executed in four key phases: needs identification, website design and development, training and mentoring, and implementation followed by evaluation. Remote interviews and surveys were conducted to assess the partner’s needs, while capacity-building activities empowered stakeholders to manage the digital platform independently. Preliminary outcomes indicate a substantial improvement in market visibility, customer engagement, and operational efficiency. The results highlight the potential of structured digital interventions to transform the promotional strategies of rural micro and small enterprises, offering a scalable and sustainable model for enhancing competitiveness in similar contexts.

Abstract

The spread of the COVID-19 virus has occurred exponentially, necessitating advanced search technologies that provide accurate information. The primary challenge in searching for COVID-19 related information involves the diversity and rapid changes in data, as well as the need to understand specific medical contexts. Unstructured information sources, such as research articles, news reports, and social media discussions, add complexity to retrieving relevant and up-to-date information. As the volume of data and information related to the COVID-19 pandemic increases, there is a pressing need for effective and accurate information retrieval systems. Transformer architecture, known for its capabilities in natural language processing and managing complex contexts, offers great potential to enhance search quality in the healthcare domain. BERT is a deep learning model that performs searches based on specific queries, with search results sorted accordingly. The ranking process uses BERT architecture to compare the performance of transformer encoders, specifically between bi-encoders and cross-encoders. A bi- encoder is an architecture where two separate encoders process two different inputs, such as queries and documents. In contrast, a cross-encoder processes two texts simultaneously using a single encoder, allowing the model to capture contextual interactions between them. Research indicates that cross-encoder performance is significantly better than bi-encoder for cases with relatively small data sets. Evaluation results show that the NDCG score for bi-encoder is 0.89, while for cross-encoder it is 0.9. The mAP score for bi-encoder is 0.7, and for cross-encoder, it is 0.89. Both bi-encoder and cross-encoder achieved an MRR score of 1.0.
