Abstract

The Mobile JKN application that has begun to be implemented in every hospital is the main factor in the success of hospital services. Quite complete features are presented in one application. The variables measured in this study were occurrence (frequency of occurrence), severity (impact), and detectability (monitoring). The research data was obtained based on the results of direct observation at Bhakti Yudha Hospital. Risk management in the use of Mobile JKN is the main topic in this study. This study aims to assess information security risks using the FMEA method. The FMEA method is an error analysis method that arises from the design process of a design work. The results of this study are in the form of Risk Priority Number (RPN) values based on: severity (S = Severity), occurrence (O = Occurrence), and level of detectability (D = Detectability), and a report on risk management results which contains a list of risk analysis priorities accompanied by root causes of problems and risk control measures.

Abstract

The Indonesia Engineers Association has used Microsoft Dynamics Axapta (AX) enterprise resource planning (ERP) software as its operational support system. However, there are obstacles that are obstacles to completing business processes effectively by users, which have an impact on declining work performance and not achieving company targets. In addition, for the next 3 years, IT solutions are also needed to be able to support business development in the company. The implementation of Enterprise Architecture is expected to be the answer for the Indonesia Engineers Association in the next 3 years, so that the company can be more productive and develop as well as there is alignment between the business strategies owned by the company to optimize the use of information systems and information technology owned by the Indonesia Engineers Association. The basis for choosing using the TOGAF ADM method in designing Enterprise Architecture is that TOGAF ADM has a complete methodology, clear and structured stages, so that the design and specifications become easier and reduce the implementation risks faced by the Indonesia Engineers Association. This research is expected to provide insights for policymakers and enterprise architecture practitioners in selecting and implementing the framework that best suits the context and needs of their organizations. In addition, this study also provides recommendations to improve the efficiency and effectiveness of the implementation of enterprise architecture in the Indonesia Engineers Association.

Abstract

Segmenting plant leaves in natural environments was challenging due to fluctuating lighting, complex backgrounds, and heterogeneous leaf morphology. This study was conducted aiming at addressing the above mentioned issues by developing a modified U-Net architecture for segmenting Eucalyptus pellita seedlings in open nursery settings. The proposed solution introduced a ResNet50 encoder pre-trained on ImageNet, enhanced regularization in the decoder, and a combined loss function comprising Binary Cross-Entropy and Dice Loss to optimize pixel-wise accuracy and shape conformity. A total of 2,181 high-resolution RGB images were collected under three distinct lighting conditions: cloudy, sunny, and scorching. All images were manually annotated, stratified, and augmented with geometric and photometric transformations. Model training employed adaptive learning rates and early stopping strategies. The results showed the highest median segmentation score of 0.867 under cloudy conditions, followed by 0.853 under scorching conditions, and 0.838 under sunny conditions. Statistical testing confirmed significant differences across lighting scenarios. Visual inspection further demonstrated the model’s ability to preserve spatial details and mitigate the impact of shadows, reflections, and cluttered backgrounds. Despite the decline in precision under sunny conditions, segmentation consistency remained high. In conclusion, the developed model successfully addressed key challenges in leaf segmentation under variable outdoor lighting. The findings support its use for robust, high-precision segmentation, offering a foundation for real-time plant health monitoring in nursery-scale applications.

Abstract

This research aims to develop an Internet of Things (IoT)-based automatic watering system with real-time monitoring features for soil moisture and pH levels, designed to support the cultivation of avocado seedlings. The system utilizes an ESP32 microcontroller connected to two soil moisture sensors and one pH sensor, and is controlled through a mobile application built with Flutter. Sensor data is transmitted to a backend server using the MQTT protocol, while communication between the application and the backend server is conducted via a REST API. Users can configure watering schedules and durations, as well as set moisture thresholds to trigger automatic watering. Testing results show that the system functions effectively in monitoring soil conditions and performing watering based on the configured settings.

Abstract

Transformasi digital di perguruan tinggi menuntut perencanaan teknologi informasi yang strategis, terstruktur, dan berkelanjutan agar mampu mendukung efisiensi akademik dan administrasi. Penelitian ini bertujuan untuk menyusun IT Masterplan Universitas Bakrie sebagai kerangka strategis pengembangan sistem informasi dan transformasi digital universitas secara holistik. Metode penelitian menggunakan pendekatan kualitatif dengan kombinasi analisis dokumen, wawancara semi-terstruktur, dan survei di lingkungan Universitas Bakrie, termasuk Biro Rektorat, Direktorat TI, dan fakultas-fakultas. Analisis dilakukan dengan mengacu pada kerangka kerja Enterprise Architecture (EA) menggunakan TOGAF Architecture Development Method (ADM) serta analisis kesenjangan (gap analysis) antara kondisi eksisting dan target arsitektur yang diinginkan. Hasil penelitian menunjukkan bahwa kondisi sistem TI Universitas Bakrie masih terfragmentasi, dengan beberapa aplikasi tidak saling terintegrasi dan data yang tersebar. Rekomendasi utama berupa rancangan arsitektur target yang menerapkan model berbasis layanan (service-oriented architecture) dan integrasi melalui middleware untuk mendukung pertukaran data lintas unit secara real-time. Selain itu, disusun pula desain data warehouse terpusat serta mekanisme tata kelola data (data governance) untuk meningkatkan akurasi dan analitik lintas fungsi. Implementasi IT Masterplan ini diharapkan mampu meningkatkan efisiensi pengelolaan sumber daya TI, mengurangi redundansi sistem, memperkuat interoperabilitas aplikasi, serta mendorong kelincahan digital universitas dalam menghadapi era transformasi pendidikan tinggi.
