Abstract

Kelompok tani Batu Belang Medal merupakan bagian dari perkebunan rakyat yang memiliki potensi budidaya teh yang baik, namun masih menghadapi berbagai kendala adaptasi teknologi. Keterbatasan akses terhadap teknologi, rendahnya tingkat adopsi inovasi, dan metode pemetaan lahan yang masih manual menjadi hambatan utama dalam pengelolaan kebun teh. Petani cenderung melakukan perlakuan seragam pada seluruh lahan tanpa mempertimbangkan perbedaan kondisi tanah dan tanaman, yang berdampak pada pemborosan sumber daya serta rendahnya efisiensi produksi. Penelitian ini mengusulkan penggunaan sistem berbasis kamera multispektral, radar, drone, dan GPS untuk memetakan kondisi tanah meliputi kadar air air dan tingkat kesuburan tanah untuk mengatasi permasalahan produktivitas. Hasil uji menunjukkan bahwa 91% titik memiliki komposisi tanah dominan 60%, dengan kadar air terendah sebesar 22%. Sebanyak 75% titik sampel mengalami defisiensi unsur hara utama (N, P, K, Mg), dan hanya 5% yang kekurangan N dan K saja. Teknologi ini terbukti mampu mengidentifikasi kebutuhan spesifik lahan, sehingga dapat membantu petani rakyat dalam pengambilan keputusan berbasis data untuk mendukung peningkatan produksi secara berkelanjutan.

Abstract

The use of ground tank constructed by Telkom University for Rainwater Harvesting (RWH), is limited to environmental maintenance due to concerns regarding the quality of water in the underground tank. Therefore, this research aims to develop a remote monitoring device that uses Internet of Things (IoT) technology to monitor the pH, water surface, submerged materials, and water clarity levels in ground tank. To achieve the requirements, pH, ultrasonic-based volume, Total Dissolved Solids (TDS), and Turbidity sensors were selected due to the IoT connectivity. The enabling device, namely the ESP 32 microcontroller and Blynk platform were installed on monitoring dashboard on a tablet computer with 4GB of RAM. The result showed that calibration of each sensor had good accuracy, except for the Turbidity sensor due unavailable materials. In conclusion, the RWH monitoring system is suitable for use.

Abstract

This paper discusses the water management conducted by Telkom University, including the fundamental considerations to be taken into account, the implementing organization, the design methods for rainwater systems, and practical experiences in constructing Rainwater Harvesting systems. The management is aware of the conditions and situations related to clean water users, estimates of clean water requirements, potential water sources, and the campus environmental situation. Based on various studies and supported by rainfall data from the Meteorology, Climatology, and Geophysics Agency, a simple calculation was used to derive the design of the Rainwater Harvesting system, which was subsequently implemented. There are several lessons learned from this implementation, including the need for improvements in the foundation structure of soak pits, recommending the construction of ground tanks during the dry season, and the flexibility of ground tank size depending on the availability of funds The abstract should state briefly the purpose of the research, the principal results and major conclusions.

Abstract

Operational disruptions on the Jakarta Light Rail Transit (LRT) during 2023–2025 indicate issues related to the signal loss between the train's communication system and surface radio devices. This research investigates the causes of signal loss through field testing, simulations, and theoretical analysis. Field testing showed a measured Received Signal Level (RSL) of approximately −79 dBm, while simulation results with Atoll and theoretical approaches ranged from −70 to −65 dBm and −50.62 to −66.18 dBm. Coverage analysis based on Atoll simulation revealed signal-free areas between adjacent Wireless Radio Units (WRUs), leading to a loss of connectivity for 1.12 second. The SINR values obtained, ranging from 2 to 8 dB, resulted in a BER of up to 10⁻² and a PER of 100%, as simulated using MATLAB. Doppler analysis confirms slow fading conditions, showing that the train's mobility factor has no effect.
