Abstract

Sarong is one of the main equipment to pray. But nowadays, sarong still has traditional form that makes children get difficulties in using sarong. Besides, the sarong motif is monotonous and can’t catch children’s interest in praying. So, we create a unique, exclusive, and interesting sarong creation for children in form of sarong instant 2 in 1 to improve the children’s motivation in praying. Instant means easy to be used and 2 in 1 means the two-side of sarong can be used. The other advantages are combination of two colors can catch the children’s interest in praying, affordable prices, and product has not been available in the market. The production is conducted from mid-April until now with total product production is 48, 32 sold product, and 15 orders.

Abstract

The high risk of glare from vehicle headlights at night often becomes a significant contributor to traffic accidents, particularly for motorcyclists and drivers of lightweight vehicles. To address this issue, a smart glare-blocking system based on a PDLC (Polymer Dispersed Liquid Crystal) film has been developed. This research proposes the design, development, and testing of a PDLC film system integrated with an LDR (Light-Dependent Resistor) sensor to automatically detect light intensity and adjust the film's opacity in real-time. The goal is to enhance driver visibility and comfort without compromising overall road safety. The experimental setup involved placing the prototype system at varying distances (0–9 meters) from a controlled light source at night. Measurements were conducted to collect data on light intensity, voltage output, resistance of the LDR, and the degree of light attenuation achieved by the PDLC film. The results showed that at a distance of 1 meter, the PDLC film could block up to 99.85% of incoming light, reducing 12080 Lux to only 17 Lux. Moreover, the film began to react at 6 meters with an output voltage of 34V. It became fully transparent at 8–9 meters with an output of 50V. The findings demonstrate that the PDLC system functions effectively in detecting potential glare and reducing its impact before it reaches the driver's eyes. This intelligent system offers a promising solution for minimizing night-driving hazards by dynamically adapting to changing light conditions.

Abstract

The impact of the spread of the coronavirus disease (COVID 19) affects all people in the world. One of the efforts by the Indonesian government to reduce the spread of the virus is by implementing Large-Scale Social Restrictions (PSBB). The impact of the PSBB can be felt directly by the community in various sectors. The existence of regulations regarding restrictions on large-scale social activities (PSBB) has resulted in a decrease in activity in all fields, one of which is tourism in the Special Region of Yogyakarta. The positive side that can be drawn from social restriction regulations is the potential for reducing pollutants that pollute urban air caused by human activities. This study analyzes data from air quality testing results in the City of Yogyakarta from the Ministry of Environment (KLH) and the number of tourists visiting Yogyakarta from the Yogyakarta City Tourism Office in 2019 to 2020. Based on data obtained from the Yogyakarta City Tourism Office from 2019 to 2019 2020 saw an average decrease in tourist visits by 70% at three tourist sites in the city of Yogyakarta, namely: the Yogyakarta Palace, Taman Pintar, and the Vredeburg Museum. Based on data obtained from the Yogyakarta Special Region Tourism Statistics Report for 2019 and 2020, there has been an average decrease in tourist visits by 71% at ten tourist sites in the City of Yogyakarta. The decrease in tourist visits affects the air quality in the Yogyakarta City environment. This can be proven by improving the quality of ambient air in the City of Yogyakarta in 2020. Reducing the level of carbon monoxide (CO) in the air in the city of Yogyakarta by 12.5%.
