Abstract

The escalating problem of plastic waste has become a serious environmental concern, particularly in coastal areas such as Puger District, Jember Regency. This community service program aimed to implement a Zero Waste movement through household waste sorting as a fundamental step in community-based waste management. The methods applied included awareness campaigns and waste-sorting training and The results demonstrated a significant increase in public awareness and participation in waste sorting, as well as waste weighing to quantify the amount and types of household waste generated before and after the intervention. Moreover, there was a notable rise in family involvement in household waste management. This initiative proves that educational and participatory approaches can effectively drive behavioral change toward a low-waste lifestyle. The household-based Zero Waste movement offers a promising model for sustainable environmental empowerment in coastal communities.Keywords: zero waste, plastic waste, waste sorting, household, community empowerment, Puger-Jember

Abstract

Sentiment analysis or opinion mining is a series of problem solving based on public opinion. The opinion is in the form of text or writing in the form of documents obtained from social media. Sentiment analysis serves to determine public opinion in responding to a policy, activity or issue that is happening and being discussed, one of which is on Twitter social media. Sentiment analysis in this study focuses on the activities of the 2020 regional elections during the Covid-19 pandemic which was held on 9 December 2020. Twitter social media works in real-time, so in retrieving research data using the Trending Topic feature to retrieve research datasets. The results of the dataset are then processed using text mining techniques and used as material for analysis to determine the public's response to the implementation of the elections during covid- 19 whether it tends to have a positive or negative sentiment, as well as knowing the opinion factors that often arise. The adoption of the Support Vector Machine (SVM) method for sentiment analysis was carried out by testing the composition of various datasets. From the test results using 4 scenarios of training data and test data, namely 90:10, 80:20, 70:30, 60:40, it is obtained that the SVM method can be implemented with an accuracy value of 87% in the data scenario of 80% training data and 20% test data. Variables that affect accuracy are the amount of data, the ratio of the number of training and test data and the ratio of the number of positive and negative data used.

Abstract

Tuberculosis, often referred to as TB, is a contagious disease caused by the bacterium Mycobacterium tuberculosis. TB primarily affects the lungs but can also affect other organs, a condition known as Extra-pulmonary TB. The disease is transmitted through the air, with the source of transmission being individuals with TB who are Acid-Fast Bacilli (AFB) positive and who sneeze or cough, releasing the bacteria into the air in the form of sputum droplets. TB can affect anyone. This research utilizes the Case- Based Reasoning (CBR) method to aid in the diagnosis of Tuberculosis. The diagnostic process involves inputting or selecting a new case that contains the symptoms to be diagnosed within the system. Then, the system calculates the similarity values between the new case and the cases stored in the case base using the Nearest Neighbor algorithm, normalized with the level of expert confidence. Testing was conducted using 50 cases from the case base and 38 new cases. The results of the system testing, using patient medical records and data obtained from literature studies, with diagnoses validated by experts, demonstrate that the system is capable of identifying 12 types of Tuberculosis with an accuracy rate of 92.3%.

Abstract

Unemployment remains a major challenge in Indonesia, primarily due to the country’s high population growth rate, which intensifies competition in the job market. One effective strategy to address this issue is by increasing the number of entrepreneurs. This study aims to examine the direct and indirect effects of entrepreneurship training, motivation, and entrepreneurial environment on students’ entrepreneurial intention, with entrepreneurship education serving as a mediating variable. A quantitative approach with a descriptive explanatory design was employed, involving a population of 492 students. A sample of 103 students from the Faculty of Economics and Business, Universitas Negeri Makassar, was selected using proportional random sampling. Data analysis reveals that entrepreneurship training, motivation, and the entrepreneurial environment significantly influence entrepreneurial intention both directly and indirectly through entrepreneurship education. The findings highlight the importance of structured entrepreneurial education as a pathway to strengthen students' business skills and intentions. These insights can serve as valuable input for educators in guiding students not only in product development but also in marketing, business evaluation, and strategic growth. Future research is encouraged to expand the scope by incorporating additional variables and diverse methodological approaches.
