Abstract

This Community Service Program was conducted at Gang Hijau Swakarya Hydroponic Garden, Meruya Selatan Urban Village, Kembangan District, West Jakarta, with the aim of improving energy independence and urban agricultural productivity through the application of renewable energy technology and environmentally based crop protection systems. The activity began with a field observation to identify the main problems faced by the partner, namely a damaged solar power system and an open garden area without adequate protection from pests and dust. As a solution, the solar panel system was repaired and upgraded from six non-functional 100 Wp modules to eight 100 Wp modules, accompanied by the replacement of the panel box and the installation of two 12.8 V 100 Ah LiFePO₄ batteries connected in parallel to increase energy storage capacity. In addition, a 2 m × 11 m greenhouse covered with insect netting was constructed to maintain stable plant growth and protect crops from pest attacks and dust exposure. The program continued with training and mentoring for the partner and local community, covering an introduction to the solar panel system and hydroponic cultivation management. The questionnaire results showed an increase in participants’ knowledge and satisfaction regarding the use of solar energy and greenhouse construction. As the closing activity, the handover of the 2025 Kemdiktisaintek grant assets was conducted and witnessed by the Head of Meruya Selatan Urban Village.

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

Penelitian ini merancang antena Substrate Integrated Waveguide (SIW) dengan modifikasi T-slot untuk meningkatkan bandwidth pada aplikasi jaringan 5G di frekuensi 3,6 GHz. Menggunakan bahan RT Duroid 5880 (εr = 2,2; tebal 1,575 mm), desain dimulai dari perhitungan teoritis, disimulasikan dengan Ansys HFSS 2015, lalu dioptimasi melalui lima tahap percobaan. Desain terbaik (percobaan ke-5) menghasilkan bandwidth 160 MHz (3,51–3,67 GHz) dan return loss −20,34 dB pada simulasi. Namun, hasil pengukuran antena fisik berbeda, yaitu frekuensi kerja 3,62 GHz dengan return loss −3,13 dB, yang kemungkinan disebabkan oleh toleransi fabrikasi, kalibrasi alat, dan kualitas konektor/kabel. Studi ini membuktikan metode T-slot efektif meningkatkan bandwidth, tetapi presisi fabrikasi dan pengukuran perlu ditingkatkan.
