Abstract

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

Abstract

Coal-derived fly ash, or CFA, is a harmful waste for humans. CFA waste handling by its processing and utilization has become the most promising approach, which not only decreases the waste's hazard level but also improves its economic potential. This research aims to recover metals from CFA and utilize them as anode material for Li-ion batteries. Iron, magnesium, aluminum, and calcium are retrieved from the CFA via a two-step hydrometallurgical method, i.e., acid leaching followed by alkaline precipitation. The leaching process utilizes various acids, such as acetic acid (CH3COOH), hydrochloric acid (HCl) and sulfuric acid (H2SO4). Metal precipitation is carried out using sodium hydroxide solution (NaOH). Morphological and quantitative metal composition analysis are investigated using a scanning electron microscope and energy dispersive spectroscopy (SEM-EDX). The physical and chemical properties of the as-prepared samples are characterized using Fourier-transformed Infra-red spectroscopy (FTIR) and Thermal Gravimetry-Differential Thermal Analysis (TG/DTA). Based on the analysis, iron, magnesium and calcium are successfully recovered in a mixed hydroxide precipitate. The type of acid affects the final morphology and composition of the product. Therefore, our approach can be considered effective in CFA waste processing and producing high-quality product.

Abstract

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. Kata kunci: Kewirausahaan, inovasi pangan, nipah, sirupABSTRACT. Entrepreneurship is one of the required competencies for students' graduation at SMK Negeri 1 Mojosongo. 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
