Abstract

A study "Effect of Milling Time on Nanostructured Hydroxyapatite Synthesis Results by Precipitation Method" in purpose to know the effect of milling time on purity, phases and size of hydroxyapatite crystals synthesized. Hydroxyapatite (HA) were synthesized by the method of precipitation by adding dropwise a solution of CaCl2 to a solution of KH2PO 4 which has been conditioned at pH 9 with stirring and heated at 40 °C for 4 hours. The resulting suspension was allowed to stand for 20 hours. Product of precipitation milled using a Planetary Ball Mill at 880 rpm angular velocity and the ratio of powder/ballmill 1:10 with milling time variation 0, 5, 15, 30 and 60 minutes. Based on the FTIR and XRD, it was concluded that the HA produced by milling time of 60 minutes has not been able to achieve high purity. Another type of calcium phosphate formed on the product is calcium hydrogen phosphate anhydrous (CHPA). The longer the milling time, the smaller the size of HA crystals. Size of HA crystals are formed on the nanometer scale is 49.85 nm; 38.30 nm; 34.84 nm; 33.44 nm and 30.44 nm.

Abstract

Preparing the young for membership is a central function of education. For better or worse, education influences human perspectives, actions, and relationships. Social Studies learning is a scientific field that cannot be separated from its role in solving problems that occur in society. Students will participate as agents of change in society that have knowledge, insights, attitudes, and understandings that are upholding sustainability. However, social studies learning is considered to not be able to maximize its role in preparing students to have competencies to support sustainability. It has not been able to maximize the role of students in society, and social studies re hereditary and still considered an elusive and boring lesson. For this reason, social studies need more Authentic Learning, which simulates a real-world environment by making it a source and a medium of learning, so that the context and allowance are used with similar situations, meaningful and connected to the real world by applying transdisciplinary learning. This paper contains a literature review on the application of learning in social studies learning to prepare students to live in harmony with the sustainable living. This literature studies refer to the theoretical aspects of : transdisciplinary learning, social studies within transdisciplinary learning, and learning outcomes related to sustainable living.

Abstract

This study examines the incorporation of Semrush into project-based learning to support university students in the creation of efficient business models. The project seeks to utilize Semrush for market research to improve students' critical thinking skills, boost their comprehension of business principles, and cultivate an entrepreneurial attitude. The study employs a qualitative research methodology with a case study design to compare a group of students utilizing Semrush with a control group. The results demonstrate that the integration of Semrush into project-based learning yields substantial advantages for students in the development of Business Model Canvas frameworks and the identification of business possibilities.

Abstract

The high maternal mortality rate associated with pregnancy, childbirth, perinatal care and babies is one of the major problems in Indonesia. Because this mortality rate shows a picture of health status in an area, as an illustration of Indonesia's human development index. The aim of the study was to analyze the classes of pregnant women and parity in improving maternal health towards success in SDG's 2030 at the Sopaah Community Health Center in Pamekasan Regency. The research design was Cross Sectional. The population was all postpartum mothers. The sample size is 104 respondents using Simple Random sampling technique. Independent variables was classes of pregnant women and parity. Dependent variables are complications of pregnancy, postpartum care, and initiation of early breastfeeding. Data were collected using a questionnaire, data were analyzed using logistic regression test (α ≤ 0.05). The results showed that there were influences between the classes of pregnant women with complications of pregnant women (p = 0.036), and there was no effect of parity on complications of pregnant women (p = 0.321). There was no influence between the classes of pregnant women (p = 0.997) and Parity (p = 0.379) with postpartum care. There was no relationship between classes of pregnant women (p = 0.059) and Parity (p = 0.447) with early initiation of inclusion. Classes of pregnant women affect the complications of pregnant women, the full participation of pregnant women can be carried out in an effort to prevent pregnant women from reducing complications of pregnant women, so that the health of mothers and babies is getting better
