Indonesia is currently being hit by the coronavirus disease 2019 pandemic, making the level of competition between companies more competitive to generate profits. This strongly encourages companies to look for ways to attract investors' attention in capital market. The purpose of this study is to analyse the effect of corporate social responsibility (CSR) disclosure and revenue growth on the firm performance of sustainable companies listed on the Indonesia Stock Exchange (IDX). This study will examine whether there is a relationship between CSR disclosure in sustainability reports and revenue growth on firm performance. CSR is measured by GRI-Standards. Firm performance is measured by return on assets (ROA), return on equity (ROE), return on invested capital (ROIC), and economic value added (EVA). A sample of 37 companies was obtained from purposive sampling method, in which companies listed on IDX must completely published sustainability reports during the 2016-2020 period. The analysis technique with panelbased data regression. The results of this research show that CSR disclosure in sustainability reports has a significant positive effect on firm performance (EVA). Revenue growth in sustainable companies also has a significant positive effect on firm performance (ROE).

The purposed of this study were: (1) determine the self-confidence of students in class XI at SMAN 5 Pinrang; (2) determine learning mathematics through the everyone is a teacher here strategy in class XI at SMAN 5 Pinrang; and (3) determine the everyone is a teacher here strategy can generate confidence students of class XI in learning mathematics in the Linear Program material at SMAN 5 Pinrang. The type of this research was pre-experimental research with data collection instruments using learning implementation observation sheets, student activity observation sheets, and questionnaire sheets. The data analysis technique wa using descriptive analysis and non-parametric statistical analysis with the Wilcoxon formula. Wilcoxon test results obtained Zcount = 4.847 and Ztable = 1.96 so that Zcount > Ztable. Thus, H1 is accepted and H0 is rejected. So the research shows that students' self-confidence can be raised through the everyone is a teacher here strategy. This was indicated by (1) the activities of students in accordance with learning through the everyone is a teacher here strategy increased because the percentage that met the aspects > 70%; (2) the percentage value of the implementation of learning was 72.2% and included in the "High" category; and (3) the percentage of students' self-confidence questionnaire responses increased by 14.3% and was included in the self-confidence category.

Katakunci: Diagnosis, Kesulitan Belajar, Relasi dan Fungsi Abstract This research was based on the results of the experiences and observations of researchers during the implementation of PPL at MTS DDI Bilajeng, that the researchers saw that there were some students who had difficulty learning mathematics. In implementing PPL, PPL students carry out the teaching and learning process for four meetings and one evaluation using a written test sheet instrument. The problems that arise in this research are 1). What are the factors that cause students to experience difficulties in learning mathematics with regard to the subject matter of Relations and Functions in MTS DDI Bilajeng; 2). What kinds of difficulties do students experience in learning mathematics in the material Relations and Functions in MTS DDI Bilajeng. The conclusions from the results of this study are 1). The factors that cause students difficulties in learning mathematics, especially in relation to the material of relations and functions, include factors from the student's own personality, the factor of the lack of student interest in mathematics because they think that mathematics is very difficult to understand and is full of calculations. As well as the lack of prerequisite knowledge possessed by students; 2). The types of difficulties experienced by students are difficulty understanding questions, difficulties in using concepts and principles, and difficulties in carrying out aspects of computation. Keywords: Diagnosis, Learning Difficulties, Relationships and Functions

The problem taken in the Service Program for the Penatahan village community through the 2022 Real Work Lecture is to increase public awareness about the importance of keeping the environment clean. The Service Program for the Penatahan Village community that we carried out starting from January 10 to February 9 2022 with the offline method. The benefits of this Service Program for us are gaining experience in applying the knowledge gained in higher education and collaborating with the community or certain communities. This Service Program aims to help the Penatahan Village community to reduce scattered waste by carrying out waste collection activities to create a clean environment. The waste problem that occurs in Penatahan Village is caused by the government not having built a garbage disposal site so that there is no place to accommodate garbage originating from households which causes a buildup of garbage. If the accumulated waste is not treated properly, it will cause environmental pollution, which will have an impact on health. After discussing, the work program carried out was that we gave garbage sacks to the people of Penatahan Village as a substitute for trash bins and then sorted the collected waste, which would later be processed into crafts as a form of implementation and solution to the waste problems in Penatahan Village.
