Abstract

Dye-sensitized solar cells (DSSC) are photoelectrochemical, alternative energy source devices that convert light energy into electricity. In this study, DSSC with various concentrations (0.1, 0.5, and 1.0 mM) of N719 dye have been successfully prepared using simple steps. The X-ray diffraction results of the TiO2 film showed that it is polycrystalline with an anatase phase (tetragonal system) having a crystallite size of about 20 nm. The absorbance spectrum of the TiO2 film and N719 dye at various concentrations was recorded by ultraviolet-visible (UV-Vis) spectrophotometer. The bandgap energy of the TiO2 film calculated by Tauc’s formula was ~3.1 eV. The DSSC prepared using the N719 dye concentration of 1 mM achieved the highest conversion efficiency (η) of 0.298 %, respectively. Subsequently, the enhancement in efficiency was ~86 % compared with the conversion efficiency of DSSC prepared with an N719 dye concentration of 0.1 and 0.5 mM.

Abstract

The SINTA (Science and Technology Index) National Indexation System is a platform developed by the Indonesian Ministry of Education, Culture, Research, and Technology to support the management of research data, publications, and community service by lecturers and researchers. However, the lack of understanding regarding how to fill in SINTA data is often an obstacle in improving research and publication track records. This community service activity aims to provide socialization and training to lecturers regarding SINTA data filling following applicable guidelines. The methods used include presentation sessions, simulations, and direct assistance as well as giving pre-test and post-tests to participants. The results of the activity showed that participants experienced an increase in understanding and skills in filling SINTA data by 86%, which had implications for increasing the visibility and academic track record of lecturers. This activity is expected to contribute to improving the quality of research and scientific publications in Indonesia

Abstract

This research aims to find the energy in the Rosen Morse potential with a kappa value equal to zero and supported by the values ​​of different variables. The method used in this research is the Romanovski polynomial method. o obtain the energy equation for the Rosen-Morse potential, first reduce the Dirac equation to a second-order differential equation of the Hypergeometric type. Through the appropriate variable substitution, an intermediate Hypergeometric equation can be obtained which is then made into a standard differential equation form of the Romanovski polynomial and the energy value cannot be solved analytically, so it is solved with the help of the Matlab application. The energy produced in a state where kappa is equal to zero has energy that increases by providing different n.

Abstract

This community service activity aims to improve awareness, knowledge, and practices of Clean and Healthy Living Behavior (PHBS) within the Ash-Samadi NWDI Islamic Boarding School Foundation through a science-based approach. The program was motivated by the low level of hygiene behavior among students (santri) due to limited facilities and a lack of scientific understanding of the importance of cleanliness. The implementation method used an action-oriented community intervention model consisting of preparation, education, implementation, mentoring, and evaluation stages. Education was carried out through interactive training, simple scientific demonstrations, and hands-on practices such as the construction of handwashing stations, waste sorting bins, and organic composters. Data were collected through observation, in-depth interviews, and focus group discussions (FGD). The results showed a significant improvement in students’ awareness and behavior regarding personal and environmental hygiene. The students gained scientific understanding of the relationship between cleanliness and health, and an environmentally conscious student group was formed to ensure program sustainability. Thus, this activity demonstrates that a science-based approach in PHBS education is effective in shaping healthy living behaviors and can serve as a model for similar implementations in other Islamic educational institutions.
