Abstract

Turning is one of the machining operations that widely used in variety of manufacturing industries. The quality of surface plays very important role in the performance of turning that significantly improves fatigue strength, and corrosion resistance. It is also affects functional attributes of parts such as light reflection, coating and heat treatment. This research aim to develop a mathematical model to predict surface roughness based on machining parameter selected (spindle speed, feed, and depth of cut) with cutting codition dry. The experiment was tested by using Trun Master TMC 320 Sinumerik 802 S machining center. After 27 specimens were cut for experimental purposes, they were measured off-line with a surface roughness tester to obtain the roughness average value. The surface roughness (Ra) could be predicted effectively by applying spindle speed (n), feed rate (Vf) and depth of cut (a) in the multiple regression model as: Y = -0.1228 – 0.0001 n + 20.940 Vf + 0.7444 a. The  average percentage deviation of the testing set was 6.429 %  for training data set This showed that the statistical model could predict the surface roughness with about 93.571 % accuracy of the testing data set. Keywords : CNC Turning, Surface Roughness, Multiple Linier Regression

Abstract

Many vocational students have low interest in entrepreneurship, despite having Entrepreneurship Education in the curriculum. It is important to understand the factors that influence entrepreneurial interest, including the role of Entrepreneurship Education and Expertise Competencies. This study aims to analyze the effect of Entrepreneurship Education and Expertise Competencies on entrepreneurial interest of vocational students, both individually and simultaneously. This research uses a quantitative design. The research subjects involved in this research are vocational students selected through cluster sampling technique totaling 211 students. The data collection method used is a questionnaire. The instrument used was a validated questionnaire sheet, and the data were analyzed using linearity test, ANOVA, and regression analysis to see the effect of independent variables on the dependent variable. The results showed that Entrepreneurship Education has a significant influence on students' entrepreneurial interest, while Expertise Competency has no significant effect individually. However, when analyzed simultaneously, these two variables show a significant influence in increasing entrepreneurial interest. In addition, significant differences were found in entrepreneurial interest among different skill groups. This study concludes that the integration between Entrepreneurship Education and Skill Competency in SMK curriculum is important to increase students' entrepreneurial interest. Future research is recommended to expand the geographical coverage and sample for greater validity as well as examine other variables that could potentially affect entrepreneurial interest.

Abstract

Sekolah Menengah Kejuruan (SMK) sebagai salah satu lembaga pendidikan vokasi yang memiliki peran strategis dalam mencetak tenaga kerja terampil sesuai dengan kebutuhan industri. Sistem Penjaminan Mutu Internal (SPMI) di SMK diperlukan untuk memastikan kualitas standar kompetensi lulusannya memenuhi atau melampaui Standar Nasional Pendidikan (SNP) dan juga dapat memenuhi kebutuhan industri. Artikel ini bertujuan untuk mendeskripsikan pelaksanaan SPMI di Sekolah Menengah Kejuruan. Metode penelitian yang digunakan adalah Systematic Literatur Review (SLR). Hasil penelitian berdasarkan 11 artikel yang telah di review menunjukkan bahwa pelaksanaan Sistem Penjaminan Mutu Internal di beberapa SMK belum efektif dikarenakan satuan pendidikan belum menerapkan sistem penjaminan mutu secara terpadu, sinergis, dan berkelanjutan. Sedangkan di beberapa SMK hasil dari pelaksanaan SPMI telah memberikan dampak yang positif terhadap kinerja dan reputasi sekolah. Dapat disimpulkan bahwa SPMI adalah sistem yang pelaksanaannya membutuhkan faktor pendukung terlebih dari internal yaitu seluruh stakeholder yang ada pada satuan pendidikan

Abstract

Berahan Kulon Village, apart from being known as a fishing and fish farming village, also has Micro, Small and Medium Enterprises (MSMEs) that produce herbal drinks known as Jamu Coro. Jamu Coro is made from rice flour and spices such as ginger, lemongrass, cinnamon, coconut sugar and coconut milk. This traditional drink has existed since the days of the Bintoro Sultanate and was served at meetings or events at the Demak Bintoro palace at that time. The existence of wedang herbal medicine coro is still maintained and preserved by the community. They are the conservators of herbal coro in Berahan Kulon Village by making herbal products in powder form. These MSMEs have problems with production equipment that is still completely manual and the production process is not good or hygienic. The problem is the quality of coro herbal products which are in the form of non-uniform powder. SMEs also find it difficult to develop large orders. Based on the society team at Sebelas Maret University, it intends to help SMEs Situ Jamu through the Community Partnership Program. It is hoped that it can improve the quality and quantity of herbal coro in powder form and improve the economy in Berahan Kulon. An output will be obtained in the form of appropriate technology for supporting the production of coro herbal medicine

Abstract

Sekolah Menengah Kejuruan (SMK) bertugas menyiapkan siswa untuk siap bekerja di industri. Agar tugas itu dapat tercapai, proses pembelajarannya harus berbasis kompetensi kebutuhan industri dan KKNI level 2. Modul pembelajaran yang memenuhi syarat itu sangat diperlukan dalam proses pembelajaran, padahal modul tersebut saat ini tidak tersedia di sekolah. Untuk dapat menyusun dan mengembangkan modul tersebut perlu dilakukan pelatihan bagi para guru produktif.Pelatihan penyusunan modul interaktif pembelajaran berbasis KKNI dan kompetensi industri didasarkan pada rumusan indikator pembelajaran setiap KD diselaraskan dengan level kompetensi KKNI level 2 sekaligus juga dengan kompetensi industri. Jika ada perkembangan teknologi baru di industri otomotif, sementara di dalam daftar KD belum ada, bisa dan sebaiknya ditambahkan. Pelatihan diberikan kepada guru-guru SMK mitra di Surakarta, jumlahnya sekitar 10 orang. Modul interaktif berbasis e-publikasi digunakan dengan memanfaatkan MOOC Rumah Vokasi. Dengan demikian proses pembelajaran berbasis teknologi dapat meningkat kualitasnya sehingga kompetensi siswa akan meningkat. Kata kunci : e-publikasi; MOOC;  modul
