Abstract

Penelitian ini bertujuan untuk mengeksplorasi potensi perangkat router metro ethernet (Nokia 7750 SR-7) dalam menyediakan layanan Broadband Network Gateway (BNG) dengan mengimplementasikan metode BGP, VPRN, dan Subscriber Management (BVSM). Metode BVSM menunjukkan keberhasilan perangkat metro ethernet dalam pengelolaan subscribers BNG dengan transisi yang efisien dari penggunaan service layer 2 (VPLS) ke service layer 3 (VPRN). Konfigurasi parameter tambahan yang diperlukan pada service VPRN, seperti policy-option, local DHCP server, dan subscriber interface memastikan optimalitas layanan BNG pada perangkat metro-ethernet. Evaluasi potensi keuntungan dari implementasi layanan BNG pada perangkat metro-ethernet menunjukkan peningkatan pada efisiensi jaringan dan pengurangan titik kegagalan dengan tidak perlu lagi digunakannya perangkat Broadband Remote Access Server (BRAS) untuk mengelola layanan BNG. Dengan manajemen layanan BNG yang lebih terpusat di perangkat metro ethernet, proses operasional dan maintenance dapat dilakukan dengan efektif, meningkatkan kualitas layanan dan manajemen pelanggan secara menyeluruh dengan cara mengoptimalkan alokasi IP Pool, monitoring user session, dan mengatasi gangguan layanan dengan lebih cepat.

Abstract

In the era of rapid technological advancement, agriculture faces increasing challenges in optimizing production efficiency and managing resources sustainably. In Indonesia, various plant types are essential agricultural commodities, yet their productivity is often disrupted by erratic weather, poor land management, pest infestations, and land-use change. This study proposes a predictive model for plant growth using a neural network implemented in the PyTorch framework, integrating multiple environmental features such as temperature, humidity, soil moisture, nutrients, pH, and NPK levels. Unlike previous works that typically focus on specific crops or limited variables, this research introduces a multivariate approach combining diverse agro-environmental data to classify plant types accurately. The model architecture was tuned using GridSearchCV, resulting in optimal hyperparameters (e.g., batch size 32, learning rate 0.001, activation: tanh), achieving high performance with Area Under the Curve (AUC) values nearing 1.0 across most classes. Visualization of network weights reveals how input features are transformed through hidden layers, providing interpretability and transparency in decision-making. The proposed system demonstrates strong generalization capability, as validated on unseen data, and offers real-time prediction feasibility for deployment on edge devices such as NVIDIA Jetson Nano. This work contributes a novel, data-driven approach to smart agriculture by enabling precise growth prediction across multiple plant types, enhancing strategic planning for resource allocation and crop management. Future work includes model adaptation for time-series forecasting and validation with live sensor inputs in real-world agricultural environments.

Abstract

Wireless sensor network loss in wireless data transmission is one of the problems that needs attention. Interference, fading, congestion, and delay are some factors that cause loss in wireless data transmission. This paper used an adaptive multi-radio model to enhance the wireless data transmission to be more robust to disturbance in a multipath fading environment. A neural network approach was used to generate the adaptive model. If we use 433 MHz as our carrier frequency with 250 kHz bandwidth and 12 spreading factors, we can get signal noise ratio (SNR) for 20 meters at about -9.8 dB. Thus, we can use the adaptive model to enhance the WSN wireless data transmission's SNR to 9 dB, automatically changing the radio configuration to 797.1 MHz frequency, with 378.1 bandwidth and 7.111 for spreading factor. Based on the result, the wireless data transmission link has been successfully enhanced using the proposed adaptive model for wireless sensor networks (WSN) in a multipath fading environment.

Abstract

Microstrip antennas are widely used in modern communication systems due to their compact size and low profile. However, they typically suffer from narrow bandwidth, limiting their performance in advanced wireless applications. This study addresses this limitation by employing a triple dumbbell-shaped defected ground structure (DGS). The antenna is designed to operate at 3.5 GHz using a Rogers RT5880 substrate, and its performance was analyzed through simulations in HFSS 15.0 software. Without the DGS, the antenna exhibits a fractional bandwidth (FBW) of only 1.71%, operating from 3.47 GHz to 3.53 GHz. Incorporating the triple dumbbell-shaped DGS in the ground layer increases the FBW significantly to 53.6%, extending the operating frequency range from 2.39 GHz to 4.14 GHz. This improvement was achieved through the careful optimization of DGS parameters. The simulated gain at 3.5 GHz is 5.13 dBi. The proposed design demonstrates superior performance compared to conventional techniques such as split-ring resonators (SRR) and Butler matrix (BM) configurations. Simulation and measurement results show excellent agreement, validating the design. The achieved ultra-wideband performance benefits 5G and next-generation systems, offering greater frequency tolerance, diverse signal support, increased capacity, and reliable operation, making the antenna a promising candidate for future wireless applications.

Abstract

The digital transformation of Hospital Information Systems (HIS) has become an urgent necessity, particularly for teaching hospitals that fulfill the triple mission of healthcare service, education, and research. The gap between technological planning and Information Technology Human Resource (IT HR) readiness is a primary barrier to implementation, even when future business process flows are carefully designed. This study intends to develop an integrated HIS digital transformation roadmap aligned with technological and IT HR strategies for the 2026–2029 period. A qualitative case study approach was used, focusing on the IT division of a teaching hospital in Indonesia. Data were collected through a documentation study of the Hospital’s 2025–2029 Strategic Plan, in-depth interviews with five key informants representing IT division, and observations. Data analysis followed a strategic cascading framework, integrating the Ward and Peppard, the Balanced Scorecard, and Bernard Marr’s Future Skills framework. The findings identify eight primary technology strategy clusters and eight IT HR competency domains encompassing technical, human, and business skills. The Balanced Scorecard analysis produced sixteen measurable strategic objectives. The resulting integrated roadmap is divided into four phases, operating on the principle that IT HR competency development must precede the implementation of new technologies. This research delivers a traceable, strategic cascading model from the hospital’s Strategic Plan to the implementation roadmap, which is replicable for other teaching hospitals in Indonesia facing the challenges of HIS digital transformation
