Solar energy is an alternative energy source that is environmentally friendly and has great potential to be utilized in Indonesia. However, the use of solar energy is still limited, especially in rural areas which have limited infrastructure and access to electricity. This research aims to analyze the use of 100 WP polycrystalline solar panels as an alternative energy source to improve the welfare of rural communities in Indonesia. The research method used is literature review, namely by examining and criticizing various reference sources that are relevant to the research topic. The data collected includes secondary data, which was analyzed using content analysis, comparative analysis and synthesis analysis techniques. The research results show that the use of 100 WP polycrystalline solar panels can provide benefits for rural communities, including: (1) increasing the availability and quality of electricity, (2) saving costs on fossil fuels (3) reducing greenhouse gas emissions, (4) improve the quality of life and public health. This research recommends that the use of 100 wp polycrystalline solar panels can be expanded and improved in other rural areas in Indonesia, taking into account technical, economic, social and environmental aspects.

Global warming is an increase in global temperature at the Earth's surface (within several thousand kilometers) compared to the normal/average value recorded over a standard period (World Meteorological Organization/WMO measurements: at least 30 years). Global warming is one of the impacts caused by the greenhouse effect. The greenhouse effect is a condition where the surface temperature of a celestial body, such as a planet or star, increases rapidly. This increase in temperature is caused by changes in the composition and conditions of the atmosphere around the object. The greenhouse effect can be caused by human activities and can occur naturally due to natural events such as forest burning due to a prolonged dry season. Basically, the greenhouse effect is very difficult to overcome, but we can reduce the greenhouse effect by using environmentally friendly energy such as renewable energy. With the rapid development of technology in this modern era, there are many renewable technologies that can be developed and utilized. This analysis aims to determine the process, causes and consequences of the greenhouse effect as well as the development and use of renewable energy technology to overcome the greenhouse effect.

consider other things such as avoiding the same or repeated schedules in one day, the number of teaching staff involved, and practicum subjects which in their implementation require a laboratory. The subject scheduling process at SMK Negeri 1 Tambolaka City is still carried out manually by Deputy Head 1 for the curriculum field, who currently uses Microsoft Excel software, which has the potential for errors and often requires correction before the schedule is implemented. Because the subject scheduling process is very important, a solution is needed in making subject schedules. Therefore, this research aims to optimize course schedules by applying a genetic algorithm to the course scheduling application. In this research, the process of preparing rosters for applied subjects was carried out at school using a web-based genetic algorithm method so that schedule collisions did not occur and the process was more optimal. In the experiment, the results of this subject scheduling application system consisted of several forms and menus, including a login form, department data menu, subject data, class data, teachers, hour ranges, special schedules, and the scheduling menu. Creating a teacher's teaching schedule using a genetic algorithm can produce a schedule automatically and systematically, thereby displaying the schedule for the day and time of each teacher's teaching schedule. The application of genetic algorithms in scheduling teacher teaching at SMK Negeri 1 Tambolaka City is a very optimal solution for scheduling, so that the possibility of similarities in the same teacher's teaching time and hours is very small.
此外，还需要考虑其他因素，如避免在一天内出现相同或重复的课程表、所涉及的教职员工人数，以及在实施过程中需要实验室的实习科目。目前，丹波拉卡市第一国民学校的科目安排工作仍由负责课程领域的副校长 1 以手工方式进行，他使用的是 Microsoft Excel 软件，该软件有可能出错，往往需要更正后才能执行。由于学科课程安排过程非常重要，因此需要一个制定学科课程表的解决方案。因此，本研究旨在通过将遗传算法应用于课程安排应用程序来优化课程安排。在这项研究中，学校使用基于网络的遗传算法方法来编制应用科目的花名册，这样就不会发生课程表冲突，使编制过程更加优化。在实验中，该学科排课应用系统的结果由多个表单和菜单组成，包括登录表单、部门数据菜单、学科数据、班级数据、教师、课时范围、特殊课程表和排课菜单。使用遗传算法创建教师教学日程表可以自动、系统地生成日程表，从而显示每位教师教学日程表的日期和时间。在坦波拉卡市SMK Negeri 1的教师教学时间安排中应用遗传算法是一种非常优化的排课方案，因此，同一教师的教学时间和课时出现雷同的可能性非常小。

One of the government's steps in the energy sector is to immediately develop and introduce renewable energy sources to reduce dependence on fossil fuels. Supporting government policies regarding community energy supply, including wind energy, requires the introduction of the use of new renewable energy sources based on local potential. To support this government program, non-profit programs are being implemented in several cities in Indonesia to exploit the potential of wind energy. Wind speed, or the average wind energy that can be harvested each day, on Mount Kinshiel ranges from 60.14 to 77.59 W per hour. On the other hand, wind speed in Gresik Regency has been unstable for 10 days, with an average wind speed of 1.5 m/s and wind strength of 10.47 watts during those 10 days. In Palu City, the PLTB electricity generation capacity is 28,308 kWh/day, and the 900 VA electricity supply from the PLTB system is distributed to approximately 31 houses (electricity consumers).

Water Quality is a term that describes the suitability or suitability of water for certain uses, for example: drinking water, fisheries, irrigation, industry, recreation and so on. Caring about water quality means knowing the condition of the water to ensure safety and sustainability in its use. Water quality can be determined by carrying out certain tests on the water. Tests that are usually carried out are chemical, physical, biological tests, or appearance tests (smell and color). For more complex measurements, water samples are needed which are then maintained, transferred and analyzed elsewhere (for example, a laboratory). Measurements like this have two problems, namely that the characteristics of the water in the sample may not be the same as the source because chemical and biological changes occur over time. Even water quality can vary between day and night and is influenced by the presence of aquatic organisms.
