Abstract

A low cost, highly sensitive sensor with easy fabrication has been successfully developed to detect variations in the concentration of sucrose solutions using a microfiber probe sensor. The microfiber probe was fabricated using a flame brushing mixture of butane and oxygen with single-mode optical fiber material and pulled on both sides to achieve a size of 16.48 µm. These microfiber probes were characterized into two sensor probe shapes: straight and u-shaped, to measure variations in the sucrose solution concentration. The results for both probe shapes showed a decrease in peak output intensity and a shift in peak wavelength as the sucrose concentration increased from 0.5% to 3%. The straight shape exhibited a sensitivity of 0.241 dBm/% with a slope linearity of 99.5% and a resolution of 0.0415%, while the U-shape had a sensitivity of 2.692 dBm/% with a slope linearity of 90.6% and a resolution of 0.0030%. The measurement spectra results indicated significant differences in u-shape at each concentration. In conclusion, both microfiber sensor probe shapes exhibited excellent performance and are suitable for use as chemical sensors to measure variations in solutions.

Abstract

It has been developed the detector method of color changing to non-invasive and economical nanofiller composite resin based on optical imaging. The method is chosen due to the easiness of information in images form to be understood. The color changing is represented by the changing of brightness intensity laser which transmitted by samples. The light source uses green pointer laser with 532 nm of wavelength of and webcam sensor which can be obtained in the local market. Fraunhofer diffraction principle is used to utilize set up and test material treatment. By utilizing IC LM 317, it is made a series of regulators so that the laser pointer can be the input voltage from voltage source (AC). The light source of laser pointer is exposed to the test materials for detecting the intensity of transmission. Samples are made as thin as possible in order to transmit light and are given treatment in form of immersion in tea and coffee solution. Immersion is done for 1 week for 4 hours per day. The transmission intensity of samples captured by webcam and processed using the Delphi program. The data collections in form of transmission intensity are in pixel scale. The results indicate that the longer time immersion used affect the transmission intensity of samples decrease. These results can be seen from graph of the relation between transmission intensity with longer time of immersion. This detector can be used to help characterization of color's stability determination on the material which is portable gear.

Abstract

Gili Iyang is known as one of the areas with the best air quality in Indonesia. However, increased human activity has the potential to reduce air quality if not managed properly. Environmentally friendly technologies, such as electric vehicles, solar shelters, and air quality monitoring devices, are potential solutions to maintain the sustainability of clean energy in this area. This activity aims to increase public understanding of the importance of environmentally friendly technology, especially electric vehicles, solar shelters, and air quality monitoring, as well as promote the application of this technology in supporting ecotourism. The methods used include electric vehicle training for junior high school students and the installation of solar shelters and air concentration monitoring equipment at the Gili Iyang Assistant Health Center. This approach is designed to provide interactive education and practical solutions to the community. The activity showed a significant increase in junior high school students' understanding of electric vehicles, with 85% of participants understanding the working principles and benefits. Solar shelters can also be very useful in supporting the provision of electricity for residents. Thus, installing air concentration monitoring devices provides real-time information that helps the public and health workers make preventive decisions regarding potential air pollution. This activity increased public awareness about maintaining air quality and implementing environmentally friendly technology. In addition, implementing air monitoring tools contributes to the sustainability of ecotourism in Gili Iyang by combining technology and community-based education.

Abstract

Limitations in electricity access and reliability remains a critical challenge for small islands and remote areas in Indonesia, constraining socio-economic development and sustainable tourism growth. This community engagement program aimed to design and implement a solar shelter system to support renewable energy utilization in Gili Iyang Island, Sumenep, widely recognized as an “oxygen island” and emerging health tourism destination. The program adopted a participatory approach involving local youth organizations (Karang Taruna) and the Kelompok Sadar Wisata (Pokdarwis) through needs assessment, system design, installation, testing, and technical training. The implemented off-grid photovoltaic system consists of a 100 Wp solar panel, a 24 V 20 A solar charge controller, a 12 V 50 Ah VRLA battery, and a 1000 W pure sine wave inverter supplying 220 V AC loads. Field testing demonstrated that the system reliably powered an automatic coconut irrigation pump and multiple electronic charging devices under typical operating conditions. Beyond technical performance, the program enhanced local capacity in basic solar energy operation and maintenance while strengthening the island’s image as a sustainable ecotourism destination. The initiative directly contributes to SDG 7 (Affordable and Clean Energy) and supports long-term renewable energy adoption in small island contexts.
