Utilization of used cooking oil in the manufacture of bar soap is one way of engineering waste products in reducing environmental pollution which will increase the economic value of a product. The purpose of this community service is to increase creativity and innovation for related partners, namely members of the Bunga Raya Waste Bank in processing used cooking oil waste into bar soap products. The method of activity is that it begins with socialization and discussion, followed by training for partners by creating small groups so that each member can be directly involved and it is easier to understand how it is made and ends with evaluation. The result of this service activity is that each member can make bar soap using used cooking oil. This bar soap is very promising to be used as a micro-enterprise by partners, namely members of the Bunga Raya Waste Bank which is a community forum that helps handle waste processing. It is hoped that through this training, the Bunga Raya Waste Bank can also provide the knowledge it gains to the community to care about the environment by processing waste into a useful product

The increasing use of household materials made of stainless steel also causes more metal waste to be produced. Stainless waste is considered dangerous because it contains several heavy metal compounds such as Ci, Pb, Ni, Fe, and others, so it is necessary to treat stainless waste. Stainless slag and stainless dust can be processed into products with high selling value such as pigments or dyes. In this research, Prussian Blue pigment was synthesized from Fe waste obtained from iron fiber waste. Apart from knowing the yield of the Prussian Blue synthesis, the effect of adding TiO2 on the intensity of the resulting color was observed. This study used a hydrometallurgical method using acid leaching to produce Prussian blue color pigments. The Prussian blue pigment conversion value produced in experiment 1 was 79.63%, experiment 2 was 80.36%, experiment 3 was 83.63%, and experiment 4 was 82.40%. The yield value of Prussian blue pigment in experiment 1 was 1.230 gram Prussian blue/gram iron, experiment 2 was 1.142 gram Prussian blue/gram iron, experiment 3 was 1.305 gram prussian blue/gram iron, and experiment 4 was 1.807 gram prussian blue/gram iron. Overall this method can process waste iron (stainless steel) into Prussian blue color pigment.

Kepedulian masyarakat dan pemerintah akan pentingnya pengelolaan sampah limbah rumah tangga masih sangat minim di lingkungan kita. Limbah rumah tangga yang belum termanfaatkan dengan baik di Desa Rejosari dapat diolah menjadi mikroorganisme lokal (MOL) yang lebih bernilai serta dapat diaplikasikan pada masyarakat setempat. Mikroorganisme lokal (MOL) merupakan larutan yang menggunakan bahan organik sebagai media untuk kelangsungan hidup dan perkembangan mikroorganisme. Larutan MOL dapat digunakan sebagai pengurai, pupuk hayati, pestisida organik, dan aktivator pengomposan. Proses produksi mikroorganisme lokal (MOL) diawali dengan tahap persiapan alat dan bahan, dilanjutkan dengan tahap fermentasi bahan, dan tahap penyaringan hasil akhir produk.

ABSTRAK. Kewirausahaan merupakan salah satu tuntutan kompetensi lulusan siswa di SMK Negeri 1 Mojosongo. Kompetensi tersebut menjadi salah satu indikator kualitas sumber daya manusia lulusan SMK. Tim Manajemen sekolah selalu berusaha meningkatkan kualitas sumber daya siswa dan tenaga pengajarnya. Salah satu terobosan yang dilakukan adalah bekerjasama dengan Prodi D3 Teknik Kimia Universitas Sebelas Maret untuk meningkatkan wawasan siswanya. Konsep kerjasama ini berupa transfer keilmuan yang dikemas dalam kegiatan pengabdian masyarakat. Kegiatan ini memiliki beberapa tahapan dimulai dari identifikasi masalah mitra yaitu perlunya pemahaman konsep kewirausahaan, business plan, pemodalan dana hibah, konsep desain dan inovasi produk dan pemasaran usaha. Pada tahap awal kegiatan siswa diminta mengikuti pretest untuk mengetahui tingkat mula pemahaman. Tahap kedua paparan materi kewirausahaan dan diskusi, tahap ketiga demo sekaligus praktik langsung pembuatan inovasi produk pangan dari buah nipah. Kegiatan diakhiri dengan post test dan testimoni hasil kegiatan. Dari kegiatan yang telah dilakukan, menunjukkan hasil bahwa terdapat peningkatan pemahaman peserta tentang kewirausahaan dan inovasi produk menggunakan teknologi sederhana.

Thus, this competency is one of the indicators to determine the quality of graduates from SMK N 1 Mojosongo. The School management has been trying to improve the quality of students and teaching staff. Collaboration between SMK N 1 Mojosongo and Diploma 3 of the Chemical Engineering Study Program of Universitas Sebelas Maret is one of the breakthroughs to increase students' insight. The concept of this collaboration is in the form of knowledge transfer which is packaged in community service activities. This activity begins with identifying the problems experienced by partners such as the need to understand the concept of entrepreneurship, business plans, grant funding, design concepts, product innovation, and business marketing. Before the main agenda begins, students are asked to take a pretest to determine their initial level of understanding. After a presentation on entrepreneurship, the students practice making food product innovations from Nypa fruticans. Finally, the students took the post-test and gave testimonials on the results of the activities. The results of this activity indicate that there is an increase in participants' understanding of entrepreneurship and product innovation with simple technology.Keywords: Food innovation, nypa fruticans, entrepreneurship, syrup
