Educational problems always arise along with the development and increase of students' abilities, situations and environmental conditions that exist due to the influence of information and culture as well as the development of science and technology. The geography subject for the material of the Theory of the Formation of the Universe according to the results of observations and interviews made to class X social studies 3 students at SMAN 3 Jember is considered boring material. This study used the classroom action research method. The research will be carried out as many as two cycles, if in cycle I it has been achieved as desired, namely achieved classical completeness, then the implementation of the cycle is stopped, but if the results achieved have not reached the desired one, then continued in cycle II by optimizing the researcher's hard work in applying the STAD learning model so that the expected goals are achieved. The results of learning activities in cycle II are better than learning in cycle I. The application of the STAD model learners has succeeded in increasing students' abilities and increasing student activity by 93.75%, growing awareness to always uphold cooperation in solving problems together so as to realize a high social sense between friends in school  

This research is motivated by the demands of society for the Islamic banking industry to innovate and develop products and services in order to meet the needs and facilitate transactions. The purpose of this study is to describe the implementation of musha>rakah mutana>qis}ah financing products as a development of musha>rakah contracts. This study uses a field research methodology that is descriptive in nature. The research location is at the Bojonegoro Branch of the Indonesian Sharia Bank. This research was conducted using primary data sources obtained directly and secondary data sources obtained from other media such as books, journals and others. This study shows that the musha>rakah mutana>qis}ah contract has undergone restructuring, which should be intended for purchasing assets (houses, shop houses, motorcycles, cars and so on) but in its implementation, the object of musha>rakah mutana>qis}ah transactions between banks Indonesian sharia and customers are assets that are fully owned by customers, where previously the customer's assets were purchased in part by the bank to leave a portion of ownership (his}s}ah) of one rupiah for the customer. So here applies the shirkah amla>k ikhtiyari contract in the form of joint ownership of assets. Then the bank's portion is acquired by the customer by purchasing it in installments according to the agreement until it is paid off and the asset is fully owned by the customer again. This is hilah/engineering in the contract that aims to get the customer to get cash. Therefore, it is more appropriate if the financing is carried out using an 'inah sale and purchase agreement, in which the customer sells his assets to the bank in cash, then the customer buys them again from the bank in installments according to the agreement. The law of buying and selling 'inah is permissible according to Syafiiyah scholars.

The purpose of this research is to determine the effect of solvency ratio, capital structure, and social responsibility on financial performance. This research uses 20 samples consisting of 5 companies in the cigarette industry subsector based on the time period 2018-2021. Data is collected from annual reports available on the Indonesia Stock Exchange (IDX). The analysis in this research uses 3 (three) approaches, including descriptive statistics, correlation, and regression. Based on the results of this research, it can be concluded that of the six elements, including ROA, ROE, DER, DAR, WC, and CSR, show good financial performance. In addition, DER and DAR measures negatively affect ROA and ROE. This is because the increase in solvency value causes the company's profit to decrease, it means that the company's high debt ownership makes the company pay higher interest so that the company's profit is small. WC and CSR have no impact on ROA and ROE. This is because the company's asset ownership can cover their current debt and CSR implementation can help convince interested parties to invest in the company. Based on the research conducted, the company should minimize the use of debt as funding in its operational activities, because it can affect the profitability of the company which causes a decrease in the value of ROA and ROE. In addition, the company should reconsider the implementation of CSR because it can help create a positive image of the company in the eyes of the public, even though the company's expenses will increase

Children are national assets who have the right to grow and develop optimally. Living on the streets is very dangerous for children. The aim of the research is to determine the application of the principle of regional autonomy in developing social welfare for neglected children and the obstacles in overcoming the problems of abandoned children in Serang City. The research uses qualitative methods with a case study approach. This research concludes that the Regional Government of Serang City, in implementing the principle of regional autonomy for the welfare of neglected children based on Law Number 23 of 2014, has the authority to make regional policies that have an impact on prosperity and general welfare in its region. The Serang City Government is responsible for providing social services to neglected children by providing children's rights and protecting them from the risks and threats of life on the streets. The obstacle to handling the problem of abandoned children is the mindset of abandoned children and families which are still oriented towards financial conditions as the main reference, thereby ignoring risks and other threats of danger. Problems with the level of education, habits of abandoned children and limited budgets provided also become obstacles to the implementation of handling abandoned children..

The background of this research is based on the results of observations with teachers and students that teachers in using audio-visual-based learning media are already creative but not maximally. From the teacher's perception, stated that they were still clueless in using IT-based media. With creativity, it is hoped that the implementation of learning will run effectively, be fun, and lead to threats to the expected quality of learning. The solution taken by the teacher is to learn more about technology, and diligently attend training. The goal to be achieved in this research is to find out the form of teacher creativity in using audio-visual media in class VII fiqh subjects at MTsS Fastabiqul Khairat Gunung Malintang. This type of research is descriptive qualitative research which is a form of the most basic research, aimed at describing or describing phenomena that exist or occur in the field. In this study the authors describe Teacher Creativity in Using Audio Visual Media in Jurisprudence Subjects at MTsS Fastabiqul Khairat Gunung Malintang. The technique of collecting data in this research is through interviews, where researchers ask for answers by way of debriefing verbally with research informants. Based on the results of the research conducted by the authors, it was found that teachers at MTsS Fastabiqul Khairat Gunung Malintang have not been optimally able to be creative in using audio-visual media seen from the four indicators of creativity. First, the smoothness of the teacher, namely being able to adapt material to the media but the teacher has difficulty mastering sources from the internet, secondly, in terms of flexibility, namely the teacher uses applications but has not been fully able to use the application fluently, the third is teacher creativity in terms of elaboration, namely the teacher adding information in the media, fourth, teacher creativity in terms of originality, that is, teachers can use audio-visual media in their classes.

The purpose of this research to revisits methods that are more effective in nonlinear Optimization with single variable polynomial functions at high degrees. Models with linear objective functions and constraint functions are Polynomials of third, fourth and fifth degree reconstructed into subproblems that are easier to solve, namely quadratic programs, using bilinear Auxiliary Functions and solved by MATLAB simulations. The method used is the development of Tawarmalani & Sahinidis' research regarding relaxation with Auxiliary Functions. Examples of nonlinear Optimization with polynomial functions are also given to illustrate the implementation of this algorithm. The results of the research show that the application of the development reconstruction method produces a global solution that is no better than the solution to the original problem so that it is not an effective alternative method to use.
