The reduction of flora at Jambi University's Pinang Masak Campus will result in higher carbon emissions. The three-month study was carried out at the Pinang Masak Campus Jambi University. This study directly measured the crown and counted the number of individual trees. There are 62 species of trees in all, totaling 1455 individuals. Motorcycles are the most common form of vehicle to enter the college area. According to calculations of carbon absorption, the rates of emissions produced by cars, 583,619 kg/hour, and 581,779.330 kg/hour, respectively, are 1,839.667 kg/hour, 583,619 kg/hour, and 581,779.330 kg/hour, respectively. According to these findings, based on positive residual emissions, the Green Open Space of Pinang Masak Campus is less able to absorb carbon emissions from automobiles.","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124560458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employed a quantitative, comparative approach. The subjects of the study were class X SMA. There are 21 students in class X MIPA and 36 students in class X IPS in SMA Nurul Fallah Kefamenanu. A questionnaire about learning independence was used to collect data. The results indicated that students in different specializated classes differed in their independence in learning. The learning independence of MIPA specialized students is 19.99% greater than that of IPS specialization students. This may be due to the inappropriate grouping of specialization classes and the existence of a negative stigma towards students enrolled in IPS specialization classes. This stigma has the potential to have a negative impact on self-confidence, learning motivation, learning creativity and student learning discipline. Therefore efforts that need to be made are to improve the system for determining specialization classes and to provide equal opportunities and support for each student to develop themselves according to their interests, talents and potential","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123392261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Chemo-Bio Entrepreneurship (CBEP) approach incorporates entrepreneurial values into learning according to the demands of independent learning. This is in response to the needs of the Industrial Revolution 4.0 era. The purpose of this research was to help motivate teachers and students to have an entrepreneurial spirit. In addition, learning chemistry and biology will be more fun and provide opportunities for students to optimize their potential to produce products. Thus, the economy of the school community can be developed, as a source of financial input for schools.

Data were analyzed using qualitative and quantitative descriptive statistics. The results showed that the understanding and skills of students and teachers before and after being given training in making compost and natural hand sanitizers were found to be increased.
