Abstract

The aims of this researchwere to find out the effect of different rotational speed of discmill to the size spreadingand uniformity index of brown sugar and to knowthe optimal rotational speed of disc mill producing size of 0,8to 1,2mm. The parameters observed were water content, fineness modulus (FM), uniformity index, grain yield,bulk density, and color. The research was conducted at five variations of rotational speed which were 800, 900,1000, 1100, and 1200 rpm with 1500 g sample for each variations.The results show that the water content ofbrown sugar is between 1,30 and 1,76%, the fineness modulus is around 1,99 to 4,74, the particle size is around0,41 to 2,79mm, the highest grainyield reaches 45,32%atactual speed of 900 rpm, and the range of bulk densityis about 721,07 to 740,40 kg/m3. The color of the middle fraction compared with commercial sugar is notsignificantly different. The color indexes of middle fraction in each treatment are IRED 0,41 to 0,43, IGREEN around0,35, and IBLUE 0,22 to 0,24. Based on the analysis of variance and Duncan’s method (α < 0,05) show that therotational speed (rpm) significantly affects to the particle size, fineness modulus, and grain yield, but not to thewater content, bulk density and color.

Abstract

The purpose of this study was to assess how safety, diversity, inclusivity, and health are integrated into the educational process at SDN 3 Cisantana to assess the learning environment. The issue arose as a result of the increasing need to ensure that schools facilitate social inclusion, psychological safety, and holistic development of students in addition to education. A descriptive qualitative approach was used in this study to collect data from educators, school administrators, and other staff members through interviews and observations. The results showed that the school has done a good job in creating an inclusive and respectful learning environment in the classroom, which is reinforced by constructive teacher-student relationships and differentiated instruction. The school has excellent infrastructure, a health unit, frequent sporting events, and disaster evacuation simulations. However, there is still room for improvement given the absence of formal written policies related to inclusive education, organized anti-bullying initiatives, and low student participation in health activities, such as student health agents. Although the school has made great strides in creating a positive learning environment, inclusive practices need to be formalized and preventive health education should be enhanced to ensure a safe, welcoming, and health-conscious learning environment.
