Abstract

Perkembangan bisnis kuliner makanan di Kota Semarang berdampak meningkatnya permintaan bawang merah goreng. Permintaan bawang merah goreng juga berdampak pada produktifitas di UKM brambang goreng “Berkah Arstyaji”. Untuk meningkatkan produktifitas dan kualitasnya berdasar permitaan customer, UKM tersebut menggunakan mesin tepat guna mesin pengiris bawang merah. Namun dalam penggunaannya selama ini ternyata masih menyimpan permasalahan yang perlu upaya penyelesaiannya. Permasalahan tersebut adalah ketidak seragaman hasil irisan bawang merah yang berdampak pada kualitas bawang goreng yang tidak homogen dan produktifitasnya kurang. Ketidak seragaman hasil irisan biasannya diselesaikan dengan alat serut tangan. Hasil survey lapangan ditemukan penyebab ketidak seragaman hasil irisan bawang merah disebabkan posisi pisau pengiris yang terpasang mendatar (0 derajat) pada disk mesin, sedangkan kurangnya produktifitas karena menggunkan mata pisau tunggal. Kegiatan ini bertujuan mengembangkan mesin perajang bawang merah di pelaku UKM Brambang Goreng “Berkah Arsetyaji” Semarang. Solusi untuk mengatasi permasalahan UKM tersebut adalah mengembangkan mesin pengiris bawang merah dengan posisi sudut pisau pengiris 45 derajat, menggunakan mata pisau jamak (dua pisau), putaran motor yang dapat diatur, dan efisien listrik yang digunakan. Metode pelaksanaan yang digunakan untuk menyelesaikan permasalahan UKM Brambang Goreng “Berkah Arsetyaji” mencakupi survey lapangan, perancangan mesin, fabrikasi mesin, uji coba mesin, pelatihan, dan pendampingan. Pelaksanaan program pengabdian kepada masyarakat memberikan hasil bahwa adanya peningkatan kuantitas dan kualitas hasil irisan bawang merah yang berdampak pada peningkatan kuantitas dan kualitas brambang goreng yang dihasilkan dam pemenuhan kebutuhan customer yang terus meningkat.

Abstract

The learning problem of SMK N 1 Petarukan students of light vehicle engineering is the low achievement in understanding light vehicle engine materials. This research aims to develop, analyse the feasibility, practicality and effectiveness of Articulate Storyline learning media in improving students' engineering knowledge. This research uses the ADDIE development model (Analysis, Design,Development, Implementation, and Evaluation). The assessment of the feasibility of the media was carried out by three experts in the material and media, the practicality of the media in the value of 12 educators in this study72 students of class XI TKR SMKN 1 Petarukan. The results of the study show that the media that learning Articulate Storyline was declared feasible and practical. Statistical analysis showed a significant improvement after treatment. From the results of the N-gain test, the experimental class achieved an increase of 56.64% (medium category) compared to the control class of only 20.08% (low category). This shows an increase in student knowledge using the developed learning media. The Articulate Storyline interactive learning media has proven feasible and effective in improving the engineering knowledge of SMK students in light vehicle engineering.

Abstract

The problem that arises during tissue culture learning is the limited laboratory facilities. The imbalance between the amount of equipment and the number of students causes the practicum to be carried out in turns for a long time, and is less efficient. The impact is that most students, after being assessed, obtain scores that are not as expected. Due to these problems, efforts are needed to utilize multimedia in virtual laboratories. This study aims to develop a virtual tissue culture laboratory at the Agribusiness Plant and Horticulture Vocational School and analyze the feasibility and effectiveness of the virtual tissue culture laboratory at the Agribusiness Plant and Horticulture Vocational School. This study uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The experimental method used is a one-group pre-test-post-test design, with the selected sample being the XI ATPH class, which has 36 students in the experimental class and 36 students as instrument testing subjects. The results showed that the virtual laboratory was categorized as feasible for tissue culture learning based on assessments by media and material experts. The virtual laboratory was also considered very practical for tissue culture learning. Based on the N-Gain Score calculation, the virtual laboratory improved tissue culture learning outcomes with a high category. This study concludes that the virtual laboratory can overcome the problem of limited practical facilities.
