<p align="justify"><em>Diapers waste generated by residents of RT 04 and RT 08/ RW 07 Sendangguwo Village, Semarang City has a large amount. Diapers waste is difficult to decompose by soil microbes. The decomposition process takes up to hundreds of years. The amount of diapers waste is quite large and disposed of anywhere can have a negative impact on the environment. Diapers waste can be used to make useful products. The absorbent gel can be used as plant fertilizer. The gel is very good at absorbing water so it can retain soil moisture and become nutrients for plants. However, not many people know about the impact of diapers waste and do not know that diapers waste can be made into useful products. It is necessary to provide knowledge about the negative impacts of diapers waste which can pollute the environment. Then it was continued with training on diaper waste management to become plant fertilizer for residents in the Sendangguwo Village, Tembalang District, Semarang City. The implementation method used is by giving socialization and hands-on practice regarding the stages of processing diapers waste into plant fertilizer. The results of the training were in the form of plant fertilizer products from diapers waste which were then packaged in plastic containers and then handed over to the community.</em></p>

<em><span lang="EN-US">Development in Rawa Buntu Subdistrict caused land use change and made green space  area  in  Rawa  Buntu  Subdistrict  decreased,  so  it  could  cause  flood.  This research  was  conducted  to  know  the  potential  of  rainwater  runoff  reduction  in each type of land cover in Rawa Buntu Subdistrict to serve as the basis for better planning in the future. The Soil Conservation Service - Curve Number (SCS-CN) method  is  used  to  calculate  the  total  rainfall  runoff  that  can  be  reduced  and  to know  the  role  of  green  space  in  reducing  rainwater  runoff.  The  result  of  the research shows that residential area dominates Rawa Buntu Subdistrict about 65% and  green  space  is  only  about  18%.  The  volume  of  rainfall  runoff  that  can  be reduced  each  month  on  AMC  I,  AMC  II  and  AMC  III  is  74,4MGal,  37,8MGal and  17,9MGal  with  green  space  contribution  of  27%,  31,2%  and  36,4%  of  the total rainfall runoff that can be reduced for each AMC condition.</span></em>
