Implementing of Students Character Education in SDN 0605 Simanuldang KKN 174 UINSU Simanuldang Jae Village

  Character education is the initial foundation needed in building a nation. Therefore, schools have an obligation to be committed to building the nation's character. In this case, of course, there are many challenges that need to be faced, one of which is the development of technology and information as a result of globalization. Modern lifestyles that influence attitudes and behavior unwittingly deviate from the values ​​and noble values ​​of the Indonesian nation. This study is to describe the character values ​​developed in SDN 0605 Simanuldang in the implementation of character education and the obstacles in implementing character education in SDN 0605 Simanuldang. This type of research is descriptive using a quantitative approach. The data collection method used in this study was interviews. The data analysis used is collecting data, reducing data, then presenting it to draw conclusions. The results showed that the character values ​​developed at SDN 0605 Simanuldang consisted of 13 characters, namely religious, honest, tolerant, disciplined, democratic, national spirit, love for the homeland, appreciating achievement, friendly, fond of reading, caring for the environment, social care, and responsibility. answer. Implementation of character education through the learning process, school rules and extracurricular implementation. There are obstacles in implementing character education at SDN 0605 Simanuldang, namely digital games, unfavorable house boundaries, the influence of TV viewing, and lack of understanding of student character

Studies on decreasing Chemical Oxygen Demand (COD) on artificial laundry wastewater using anaerobic-aerobic biofilter dipped with bio ball media

This study aims to determine the effect of discharge variation on the efficiency of decreasing COD parameters contained in artificial laundry wastewater. In this study used a combination of two biofilter reactor dipped with bio ball media with each condition that is anaerobic and aerobic. Drainage of waste carried out continuously and upflow is the direction of the streamline. The research begins with seeding phase which aims to grow microorganisms derived from domestic IPAL sludge unit then followed by acclimatization phase which aim to adapt microorganism with artificial laundry wastewater. After the acclimatization phase is completed, the running process starts by operating three variations of discharge that is 0.625 l/hr, 0.833 l/hr, and 1.25 l/hr. The results showed that the operation of the three variations of discharge did not give a significant influence in setting aside the COD parameters. The percentage of COD removal achieved by each of these debit operations is 82%, 83%, and 81%. In addition, the combination of anaerobic and aerobic dipped biofilter is also able to eliminate surfactant and TSS with the achievement of 90% average removal percentage
