Salah satu masalah yang sering dihadapi oleh para petani, terutama petani sayuran adalah serangan hama yang dapat menggagalkan panen. Petani pada umumnya menggunakan pestisida kimia untuk membasmi hama tersebut karena pestisida kimia banyak dijual di pasaran dan sangat efektif dalam membasmi hama. Namun, penggunaan pestisida kimia, apalagi pada jangka waktu yang lama dan terus-menerus sangat berbahaya. Alternatif penggunaan pestisida organik yang jauh lebih ramah lingkungan dan tidak beracun merupakan solusi yang lebih baik untuk menggantikan peran pestisida kimia. Tujuan spesifik kegiatan pengabdian ini adalah memberikan pengetahuan yang memadai kepada petani sayur mengenai bahaya pestisida kimia dan kelebihan pestisida organik serta untuk mengembangkan potensi bahan-bahan alam sebagai bahan baku pembuatan pestisida organik sehingga dapat meningkatkan hasil panen dan nilai ekonomi sayuran. Hasil dari kegiatan pengabdian ini menunjukkan masyarakat sangat antusias untuk menggunakan pestisida organik sebagai pengganti pestisida kimia.

Cooking oil is one of the needs of society in order to fulfill daily needs. The economic condition of Indonesian people is very diverse, some use cooking oil for single use but some also use cooking oil for several times usage. The high unsaturated fatty acids in cooking oil, cause cooking oil will be easily damaged in the process of frying (deep frying) because in the process of frying, oil will be heated continuously at high temperatures. The use of used cooking oil or jelantah can cause adverse effects to the commu- nity  and  the  environment.  The  adverse  impacts  on  the  community  are  caused  by the decline in  the quality of  food  fried with cooking oil which results  in  disruption  of  public  health. Adverse  impact  to  the  environment  is  the  disposal  of  cooking  oil  without  first  processing  can  pollute  the  soil  and  water  environment. Utilization of used cooking oil as kerosene replacement fuel is one solution that can be tak- en when facing the bad impact of used cooking oil. In order to serve as a substitute fuel for kerosene, jelantah oil must have karaketristik that is almost the same as kerosene. One of the most important characteristics is the viscosity number. Wrinkled oil has a high viscosity, so that the use of jelantah oil must undergo certain processes to decrease its viscosity. One way to reduce viscosity is by warming at high temperatures over long periods of time. Partners   in   this   devotional   activity   are   the   vendors   of   gorengan   around the  campus  of  UNNES  FMIPA.  They  use  a  lot  of  cooking  oil  in  their  business,  maybe  even  cooking  oil  used  many  times  and  waste  of  used  cooking  oil will  be  thrown  indiscriminately  so  as  to  pollute  the  surrounding  environment. With this devotion is expected the traders gorengan around FMIPA UNNES campus can process waste used cooking oil into fuel substitute kerosene so that will reduce environmental pollution.
