Abstract

Community Service Activities for Salt Farmers to Increase Salt Production in Paluh Sibaji Village, Pantai Labu District, Deli Serdang Regency, North Sumatra were carried out by providing assistance in the form of building evaporation houses and providing material assistance for repairing and building goat pens for salt farmers. The purpose of this activity is for salt farmers to increase their salt production capacity by increasing the speed and effectiveness of the production process. The method used is the construction method of a semi-elliptical evaporation house whose supports are made of elastic plastic pipes with iron reinforcements inside the pipe so that water vapor will flow through the pipes and plastic formed in a semi-elliptical construction. Community service activities were carried out by building an evaporation house for the salt production process. In addition, the community service team provided material assistance for the construction and repair of goat pens for salt farmers. Livestock farming for salt farmers is a common side business carried out by salt farmers to support household economic needs. The results of the activity were the construction of a semi-elliptical evaporation house that will be used by salt farmers to increase salt production and assistance to salt farmers in the form of material assistance for the construction and repair of salt farmer's livestock pens.

Abstract

Hybrid quantum systems that integrate solid-state qubits with superconducting circuits have emerged as a promising architecture for scalable quantum information processing. Achieving strong coherent coupling between distinct quantum subsystems, such as spin ensembles and microwave resonators, remains a critical challenge in realizing hybrid quantum technologies. This study aims to engineer and characterize a hybrid platform that couples nitrogen-vacancy (NV) centers in diamond with a superconducting coplanar waveguide resonator. A combination of cryogenic microwave spectroscopy and time-domain measurements was employed to evaluate coupling strength, coherence times, and collective spin photon interactions at millikelvin temperatures. The experimental results demonstrated a vacuum Rabi splitting of 22 MHz, confirming the realization of a strong coupling regime between the NV spin ensemble and the superconducting resonator. The coherence lifetime of the NV centers remained above 100 ?s under optimized magnetic field alignment, ensuring stable quantum-state transfer. The findings reveal that hybrid systems combining spin-based and superconducting components can serve as viable interfaces for quantum memory and quantum communication nodes. The study concludes that engineering such strong spin–photon coupling represents a foundational step toward the development of coherent, scalable hybrid quantum networks.
