Selection of Diffraction Measurement Range and Its Effect on X-ray Diffraction Rietveld Analysis Results: a MgO-Y2O3 Mixture Case. X-ray diffraction data analyses for a MgO-Y2O3 (30% Y2O3 by weight) ceramic composite have been done at various diffraction angle ranges to evaluate the effects to the analyses results. The study was performed as choosing the angle ranges correlates to data collection time and x-ray tube lasting. The analyses utilised Rietveld-based software Rietica. The ranges chosen were (A) 10-100, (B) 10-90, (C) 10-80, (D) 10-70 dan (E) 10-60 °2θ. Results showed that in general the errors of the refined parameters increased with narrower range. Phase composition analyses also showed significant bias when narrower range was used – with range 10-80 °2θ gave tolerable result. Moreover, narrowing diffraction angle in the analysis significantly biases the Lorentzian peak broadening component values particularly for phase with crystallite size estimate more than 100 nm. The study recommends how to choose the range.

Climate change is the impact of global warming which has a negative impact on daily human activities. The negative impacts of climate change are increasing sea surface temperatures, changes in rainfall, extreme weather intensity and high waves. Pollution of carbon pollution is one of the problems that exist in environmental accounting. Through disclosure of carbon emissions, stakeholders can measure the company's role in reducing greenhouse gas (GHG) emissions and also indicate that the company cares about the environment. The purpose of this study is to determine the simultaneous and partial effects of PROPER Rating, Industrial Type, and Audit Committee influence on Carbon Emission Disclosure. The objects used as samples in this study are non-financial companies listed on the Indonesia Stock Exchange for the 2018-2021 period. The technique used in this study was purposive sampling with a total sample of 23 samples from 509 companies. The data analysis model used in this study is multiple linear regression analysis. This study gives the result that the PROPER Rating, Industrial Type, and Audit Committee variables simultaneously influence Disclosure of Carbon Emissions Keywords: Carbon Emission Disclosure, PROPER Rating, Industrial Type, and Committee Audit

Stunting is a chronic nutritional problem that is still a public health challenge in Indonesia, including in Cimahi City, which has a stunting prevalence of 9.4%. One of the efforts to prevent stunting is increasing exclusive breastfeeding coverage, which is still below the national target. This community service activity aims to increase the capacity of health cadres in breastfeeding counselling knowledge and skills through intensive community-based training. The program will be carried out in March 2025 in RW 06 Melong Village, the working area of the Central Melong Health Centre, Cimahi City, with eight cadre participants. Evaluation was carried out through pre-test and post-test using a questionnaire consisting of 20 questions that had been tested for validity and reliability, as well as participatory observation of changes in attitudes and skills of cadres. The results showed an increase in the average knowledge score of 33.1 points with a significant paired t-test result (p = 0.001). Qualitatively, participants showed increased self-confidence, skills in practising lactation techniques and oxytocin massage, and initiatives to form breastfeeding support groups to sustain education. This program contributes to cadre empowerment and is a potential strategy to support the acceleration of stunting reduction at the community level.

People with disabilities, especially students at SLB Negeri Ungaran, have the same right to live a healthy and active life as other individuals. One way to achieve this is through physical activity such as Creative Dance. Creative Dance has many benefits for people with disabilities, both physically, psychologically, and socially. Physically, it helps to improve physical fitness. Psychologically, it increases confidence, reduces stress, and helps overcome anxiety and depression. Meanwhile, in the social aspect, it provides opportunities for people with disabilities to interact with others, build social relationships, and increase a sense of togetherness and inclusion in society. Participation in group activities can also increase motivation as well as provide positive emotional support. The purpose of this community service activity is to increase the independence, motor skills, and confidence of people with disabilities through physical activities based on creative dance. The implementation methods in this activity are (1) socialization, (2) training, and (3) mentoring. This activity was attended by 151 students with disabilities. During the implementation of the service, the participants showed enthusiasm, this can be seen from the attendance of 90% of the participants and active involvement in the creative Dance session. The result of this service activity is to have a positive impact, both physically, psychologically, and socially, on the participants. Creative Creative Dance has proven to be an effective medium to improve the fitness, creativity, social interaction, and confidence of people with disabilities.
