Abstract: Lampit is one of the customary apparatuses for handling rice fields to even out the land for establishing rice. The activity caused different objections in the outer muscle framework, particularly in the rump and back by reason of the little size and hard stick of the lampit. Improvements were made to overcome this situation by designing a flat seat with foam pads and adjusting the press lever found on the attached rod. This experimental research study used the same subject design, chose 30 examination subjects from ranchers in Dusun Semaja Bengkelsari, Tabanan Bali. The musculoskeletal system's complaints were obtained by using the Nordic Body Map which was measured before and after repairing the lampit design. The data were contrasted and the mean qualities when improvement, analyzed using the paired t-test (α = 0.05). The result showed a decrease in the musculoskeletal system by 51.52% (p <0.05). It could be concluded that by repairing the design of the lampit reduced complaints of the musculoskeletal system, it is recommended to continue to use and improve the lampit that has been repaired for farmers.

Abstract: The shape of the radiating patch exerts a great influence on the performance of the microstrip patch. The vital target of this research article is to constitute the microstrip antennas of rectangular, elliptical, triangular and square patches on FR4 substrate employing partial ground that notably lower the shape complexity and hence the antenna size reduction with profitable results on the basis of the center frequency of 8.5 GHz. The execution specification, such as S-parameter, gain, VSWR, and the directivity of the antenna, is investigated using ANSYS HFSS 13.0 software, which reveals beneficial outcomes of dual-band operation over the entire band frequency range of 5-15 GHz. The antenna gives poor results without any modification to the ground structure. But good bandwidth, dual band nature, better gain directivity, VSWR, and the best efficiency are achieved by the introduction of partial ground in the design of all the shapes. This is applicable for Marine Radar Communication (SART), Effective Satellite Communications, and Wireless Communication applications like weather monitoring, defense, and military purposes.
