Talking about the sustainability of life, humans cannot be separated from their dependence on energy needs. Most of the energy sources that we have used so far are fossil energy sources that are non-renewable. With the high dependence of humans on energy, innovation is needed to minimize energy limitations. One form of new renewable energy that can overcome this is Biogas. Biogas is a gas that can be obtained from the fermentation of livestock waste through technology in the form of an airtight tube called a biodigester which is useful in processing livestock waste into biogas energy. Through research that the group conducted using the literature review method, we found one village in Riau that has succeeded in utilizing biodigester technology to make biogas, namely Mukti Sari Village, Tapung District, Kampar Regency, which has now succeeded in becoming an energy independent village.

The problem that often arises now is the increase in living costs while income remains constant. With empty land in the household that is not being utilized optimally, this should be an opportunity for housewives to help improve the household economy. One solution to utilize this empty land is through hydroponic plants. This hydroponic plant uses organic fertilizer so that the hydroponic plant is good for family consumption and distribution in supermarkets. By utilizing hydroponic plants, housewives can help improve the family's economy so that the family's needs can be fully met. In this research, the researcher conducted an interview with one of the housewives who had used her yard through hydroponic plants that she had developed herself since 2017. The aim of the research was to determine the economic improvement experienced by housewives after using the hydroponic system.

This research was motivated by the discovery of several problems faced by students, namely poor interest in learning, such as the level of activeness of students during the learning process and low interest of students in SKI learning. Students felt that in this learning there was no passion or interest, as indicated by students being less active in the learning process and student involvement in the SKI learning process also decreased. With these conditions, students quickly get bored and are not interested in participating in learning. As a result, difficulties arise that affect the learning objectives to be achieved. This study aims to determine the relationship between learning strategies and learning media with interest in learning Islamic Cultural History class VIII at MTsN 1 Bukittinggi. The type of research used in this research is quantitative, correlational. The population is all class VIII students with a total of 347 students spread across 11 classes. The sample in this research used the Probability Sampling technique using Simple Random Sampling, and the total research sample was 78 students. Data was collected through questionnaires, observation and documentation analyzed using normality tests, linearity tests, multiple correlation analysis and hypothesis testing. Based on the results of the research that has been done, the results show that there is a relationship between learning strategies on student interest in learning in the subject of Islamic Culture History class VIII at MTsN 1 Bukittinggi City and the relationship between learning media on student interest in learning in the subject of Islamic Culture History class VIII at MTsN 1 Bukittinggi City, as evidenced by the results of the Pearson Product Moment correlation test on the relationship between learning strategies and interest in learning with a Pearson correlation value of 0.382 and a significant value of 0.001 <0.05. While the Pearson correlation test results on the relationship between learning media and interest in learning are 0.236 with a significant value of 0.038 <0.05. Furthermore, the results of the Pearson correlation test on the relationship between learning strategies and media with learning interest are <0.05, which is certainly valid and related. Based on this value, it can be seen that the relationship between learning strategies to interest in learning is interconnected and the relationship between learning media to interest in learning is interconnected, so Ha is accepted.

The purpose of this study was to analyze the effect of compensation, work discipline and work environment on job satisfaction at PT Telkom Akses Semarang. The population in this study were all employees of PT Telkom Akses Semarang, totaling 73 people. Sample / respondents taken as many as 73 respondents, by measuring the census technique. The results showed that the compensation hypothesis test had a positive and significant effect on job satisfaction (t count = 3.225> t table = 1.671 with a significance figure = 0.002 < ? = 0.05 (significant). Thus, the hypothesis (H1) that compensation has a positive effect on job satisfaction is proven. Work discipline has a positive and significant effect on job satisfaction (t count = 3.182> t table = 1.671 with a significance number = 0.002 < ? = 0.05 (significant). Thus, the hypothesis (H2) that work discipline has a positive effect on job satisfaction is proven. The work environment has a positive and significant effect on job satisfaction (t count 5.645> t table = 1.671 with a significance number = 0.000 < ? = 0.05 (significant). Thus, the hypothesis (H3) that the work environment has a positive effect on job satisfaction is proven. The regression coefficient ?1 = 0.284 (positive sign) means that the greater the compensation received, the greater the job satisfaction. The regression coefficient ?2 = 0.277, (positive sign) means that the more work discipline, the higher job satisfaction. Regression coefficient ?3 = of 0.476 (positive sign) means that the more comfortable the work environment, the higher the job satisfaction at PT Telkom Access Semarang.

Data collection on employee attendance at a company is a must, with the aim of monitoring discipline, calculating employee salaries, and other needs. Data collection on employee attendance at companies that are used today is very diverse, following the development of technology. The United Tronik Semarang office, which employs relatively many employees, currently uses a manual card attendance data collection system that attracts researchers to make the United Tronik Office the object of research.
 Fingerprint is one of the hardware used to support employee attendance data collection which is relatively simple and easy to reach, the accuracy and ease of operation make the fingerprint attendance system more and more in demand. One of the human error problems in the attendance data collection system is attendance recording errors, especially for employees with shift work hours. Arrangement of work shifts in programs built with Visual Basic 2010 can minimize attendance recording errors, because it can set the recording time for employees. To support the ease of data access and shift settings, the researcher uses a Client Server database system with SQL Server 2005 Software.
