Abstract

The productive unemployment rate in Central Java is quite high, of which 13.5% are vocational graduates. Entrepreneurship can be a solution to reduce productive unemployment. However, to run entrepreneurship requires strong interest and motivation. This community service is carried out to increase the entrepreneurial spirit of students at SMK Muhammadiyah 4 Surakarta. The implementation stages include analysis of partner problems, data collection, presentation and training, filling out post-socialization questionnaires, and evaluating the results of the implementation. Tips and tricks, challenges and obstacles, the importance of motivation in entrepreneurship are the main material presented in the presentation. In the training, students make business plans based on their individual choices. The percentage of consideration in the business field choosing is dominated by the suitability of majors in SMK (about 40%) and the trend that is developing (20%). While, the reasons for the suitability of hobbies, family background and others are 18%, 14%, and 8%, respectively. The students' understanding and interest in entrepreneurship increased significantly. This increase can be seen from the change in the percentage of students' plans after graduation. The number of students who wish to work in agencies or companies is around 70% (before socialization) and about 30% (after socialization). The number of students interested in entrepreneurship increased from 15% to 68%. These results show that the students' interest has shifted from "becoming an employee" to "becoming an entrepreneur".

Abstract

Using methanol, this study examined the hydroxylation process of epoxidized tamanu seed oil (ETSO), with an oxirane number of 3.92 to 4.04 mmol/g, under the catalyzation of sulfuric acid (H2SO4). The objectives of this study were, first, to synthesize polyol from ETSO, and, second, determine how temperature and catalyst concentration play a role in the hydroxylation process. During the experiment, a second-order reaction kinetic model was used for analysis. The hydroxylation process was conducted in a batch reactor for 4 hours under constant temperatures and stirring speed. During the experiment, the samples were taken every 30 minutes. The oxirane number of ETSO and the concentration of polyols were used to the reaction rates. The optimal conditions were found at a temperature of 65°C, with a methanol-to-epoxide mole ratio of 4:1 and a catalyst concentration of 3%. The pre-exponential factor (A) and the calculated activation energy (Ea) were found to be 59,041.74 g.mmol-1.min-1 and 44.69 kJ/mol, respectively. This research, therefore, has successfully identified the optimal conditions for the synthesis of bio-based polyols from tamanu oil.

Abstract

Mitra pengabdian masyarakat ini adalah perajin batik Serat Merapi yang berdiri sejak tahun 2013. Proses identifikasi permasalahan yang ditemui dan dihadapi oleh mitra telah disepakati bersama terdapat dua masalah utama, yaitu aspek produksi dan aspek pemasaran. Secara umum tujuan dari program ini adalah peningkatan dan perbaikan usaha mitra dalam aspek produksi dan pemasaran. Metode pelaksanaan kegiatan dilakukan dengan pemberdayaan masyarakat (participatory rural appraisal). Prosedur kerja kegiatan terdiri dari persiapan, sosialisasi, serta penyelesaian masalah mitra dalam aspek produksi, dan manajemen.Dilanjutkan dengan evaluasi bersama, serta terakhir pelaporan dan publikasi. Hasil pengabdian yang dilakukan untuk meningkatkan produktivitas batik tulis melalui penggunaan kompor listrik mampu meningkatkan antusiasme semua anggota kelompok batik tulis Serat Merapi. Penyuluhan dan demonstrasi alat mudah diikuti dan dipahami oleh semua anggota Serat Merapi. Hasil analisis biaya menunjukkan bahwa adanya penghematan dalam penggunaan kompor listrik dibandingkan dengan kompor minya tanah. Kebutuhan biaya dalam satu bulan untuk kompor listrik hanya sebesarRp 58.410,00 sedangkan untuk kompor minyak tanah sebesar Rp255.000,00. Selain itu, kelebihan yang ada pada kompor listrik adalahkemampuannya disesuaikan dengan daya listrik rumah produksi, terdapat pengatur suhu optimal lilin (malam), lilin lebih cepat mencair, dan kualitas lilin yang dihasilkan cukup baik. Hasil pengabdian yang dilakukan dapat dikatan berhasil, terutama karena memberikan tambahan pengetahuan dan penerapan teknologi pada kelompok batik tulis serat merapi.
