Insect attacks are a very complicated problem in rice cultivation that cause a decrease in rice productivity. It is very important to not use pesticides to kill pests due to environmental and health issues. This study aimed to solve the pest problem by installing solar-powered pest-control technology using waves of ultraviolet light and ultrasonic sound (UVUS, the name of the product). The development of UVUS involved not only innovation from startups but also the adaption of existing technologies such as batteries, solar panels, and sensors. A location-allocation model has been developed in accordance with a flower pollination algorithm (FPA) and sustainability considerations to solve the problem of rice productivity using the innovative technology of solar-powered pest control. The mixed-integer linear programming (MILP) approach was used to determine the number of UVUS required to minimize the areas missed by the ultraviolet light and ultrasonic sound. Numerical analysis of a case study of Delanggu Village showed that the model can be used to determine the number of UVUS required to only miss a certain minimal area. The results show that the proposed model can be applied to solve pest control and can provide promising economical, social, and environmental outcomes.

We tested walking interventions using adjustable air‐insoles with hardness values of 80, 160, and 240 mmHg over walking durations of 10 and 20 min. Optical coherence tomography (OCT) was used to measure the thickness of the stratum corneum (SC) and living epidermis (ED) in three different locations: the big toe (T1), first metatarsal head (M1), and second metatarsal head (M2), and deep learning was used to compare the difference in thickness between SC and ED. The results indicate that SC thickness increases in M1 is statistically significant after 20 min walking interventions using 80 mmHg insole hardness, and SC thickness decreases in T1 and M1 are statistically significant after 20 min walking using 160 mmHg insole hardness. Changes in SC and ED thickness observed in this study highlight their potential relevance in evaluating plantar tissue health in the context of DFU prevention.

Pest problems are the most frightening scourge for farmers in the process of cultivating Rojolele rice which has high rice characteristics and fragrant aroma, so it is necessary to have environmentally friendly technology assistance to assist farmers in controlling pests such as sparrows and leafhoppers. Startup Ecokarsa's solar-powered pest control technology by utilizing ultrasonic waves to make sparrows uncomfortable and ultraviolet to collect leafhoppers at one point is expected to be a solution for the Sanggar Rojolele farmer group to help control pests in the rice fields of Delanggu without damaging the environment. Because this technology is considered quite expensive for the Sanggar Rojolele farmer group, an appropriate location and allocation system is needed to determine how many points are efficient and where these points are located so that the rice fields in Delanggu are safe from attacks by sparrows and leafhoppers.
