Abstract

This study aims to determine the effect of self-efficacy on learning outcomes of vocational high school students in the context of implementing a competency-based curriculum. The approach used is quantitative with an ex post facto method. The study population was grade XI students of SMK Nasional Malang, with a total sample of 92 students taken (saturated sampling). Self-efficacy data were obtained through a questionnaire using a Likert scale, while learning outcome data were obtained from mid-semester report card scores. The results of the linear regression test showed that the data were normally distributed and had a linear relationship. The t-test showed that self-efficacy had a significant effect on student learning outcomes (p < 0.05). These findings confirm that self-efficacy is an important indicator in supporting the achievement of learning outcomes, especially in vocational education that demands students' independence, responsibility, and readiness to face the challenges of practice-based learning. Students with high self-efficacy tend to have better learning motivation, are able to manage learning strategies effectively, and demonstrate a high level of independence in completing assignments. Therefore, learning development in vocational high schools should not only emphasize technical aspects, but also need to strengthen students' self-confidence in achieving learning success.

Abstract

Lonjakan permintaan jamu terkendala perajangan herbal UMKM yang lambat dan tidak seragam, sehingga ekstraksi kurang optimal dan kualitas tidak konsisten. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan efisiensi dan kapasitas produksi UMKM Hanacaraka Herb di Kota Malang melalui penerapan mesin perajang rempah otomatis berbasis motor listrik. Dimana, proses perajangan manual yang lambat, membutuhkan banyak tenaga kerja, dan menghasilkan potongan tidak seragam. Metode pelaksanaan meliputi observasi lapangan, perancangan dan pembuatan mesin Teknologi Tepat Guna (TTG), pelatihan penggunaan, serta pendampingan di lokasi mitra. Mesin yang dihasilkan memiliki kapasitas ±100 kg/jam dengan hasil rajangan seragam dan higienis. Hasil penerapan menunjukkan peningkatan kapasitas produksi hampir lima kali lipat, pengurangan waktu produksi 75%, serta peningkatan keseragaman dan higienitas produk. Secara kualitatif, mesin ini memperbaiki konsistensi rasa dan warna jamu, menguatkan citra merek, meningkatkan efisiensi tenaga kerja, dan membuka peluang perluasan pasar. Penerapan TTG ini terbukti efektif menjawab kendala produksi UMKM jamu dan meningkatkan daya saingnya.

Abstract

Penelitian ini bertujuan menganalisis pengaruh media pendingin air mineral dan air cucian detergen terhadap kekuatan tarik baja ST 37 hasil pengelasan SMAW. Metode yang digunakan adalah eksperimen dengan variabel bebas berupa jenis media pendingin, sedangkan variabel terikatnya adalah kekuatan tarik. Proses pengelasan dilakukan menggunakan elektroda LB-52U pada arus 90 A, kemudian spesimen didinginkan dengan air mineral atau air cucian detergen pada suhu ruang. Uji tarik menggunakan Universal Testing Machine menghasilkan tegangan tarik maksimum sebesar 234,2 MPa untuk pendinginan air mineral dan 110,0 MPa untuk pendinginan air cucian detergen. Perbedaan ini menunjukkan bahwa pendinginan cepat dengan air mineral lebih efektif meningkatkan kekuatan tarik, sedangkan kandungan kimia pada air cucian detergen berpotensi menurunkan performa mekanik melalui laju pendinginan yang lebih lambat dan potensi korosi awal. Hasil penelitian ini memberikan kontribusi dalam pemilihan media quenching yang tepat serta pemanfaatan limbah cair secara bijak.

Abstract

The Coordinating Minister for Maritime Affairs believes that Indonesia is experiencing an increase in exports, particularly in the fisheries sector. This is very important because Indonesian waters consist of 44.7% fish, and fisheries are one of Indonesia's key commodity advantages. However, abundant natural resources alone do not guarantee that a nation will become superior if not accompanied by good human resources as well. The issue of fish drying is a crucial problem in the fish processing sector, including for UKM Jaya Utama in Probolinggo City. UKM Jaya Utama still uses traditional drying methods, relying on sunlight as the main drying tool. As a result, UKM Jaya Utama faces drying challenges during the rainy season. The cartridge heater-based fish dryer machine is a machine specially designed for drying and preservation, offering an alternative solution for fish drying during the rainy season and extending the shelf life of the fish. The research method used was an R&D approach with mackerel fish as the research sample, with a capacity of 10 to 15 kg per drying cycle. The machine trial results showed improved work efficiency by reducing the drying duration from 6 hours without the machine to just 2 hours, with potential profit increases of up to 3.6 times.
