Optimization of CNC wet milling cutting parameters for stainless steel AISI 304 was successfully attempted by using Taguchi method (S/N ratio and ANOVA). L9 orthogonal array is utilized for designing the experiments with 3 levels of spindle speeds and feed rates with an increment depth of cut. The effect of cutting parameters on surface roughness was examined. According to S/N ratio’s response table, the result obtained for spindle speed fervently indicates that spindle speed is the most pivotal factor for impacting the surface roughness than feed rate for stainless steel AISI 304. ANOVA results depicted that the contribution percentage of spindle speed for surface roughness is higher than feed. Optimum values of cutting parameters were endowed at a spindle speed of 3184 rpm and a feed rate of 1528,4 mm/min. The experimental values at optimum cutting condition were compared with predicted values and it reveals a significant congruity with the experimental results with a low error percentage. Therefore, this experiment aims to develop the productivity and quality of CNC milling operations for stainless steel AISI 304. In addition, number of studies for cutting parameter optimization stainless steel AISI 304 was not barely done yet. Hereafter, more investigations still needed to optimize the cutting parameters of this stainless steel AISI 304 for various machining operations specifically on CNC milling process.

The mold generally consists of two parts, namely the cavity and the core. CAD and CAM are solutions that can meet the needs of cavity and core fabrication. The CAM process is displayed to get a program in the form of a code file which will later be entered into the CNC machine. This study aims to be able to design and plan the process of making cores on plastic plate molds and being able to program core plate molds with software. This research was conducted to determine the process of making core plate molds. To determine the spindle speed and feed speed for each tool, see the cutting speed reference. From all stages of core plate manufacture with MasterCAM software, several machining processes are produced, namely drill, tap, boring, surface roughing, surface semi-finishing, and surface finishing. The total time required to complete all processes is 42 hours 48 minutes 11 seconds.

Until now, the maturity level of teachers and students in vocational education in applying 21st century skills in learning is still a prolonged polemic. This study aims to: (1) analyze the maturity level of teachers and students in applying 21st century skills; (2) analyze the difference in the maturity level of 21st century skills between teachers and students in implementing vocational learning. The research uses an exploratory descriptive method with a quantitative approach adopting the Hoy and Adam design. This study involved 598 samples which were divided into teacher and student subjects. Collecting data using a closed questionnaire technique with a 4-point Likert scale. Data were analyzed descriptively quantitatively to describe the percentage of maturity level and independent sample t-test to determine the difference in maturity between teachers and students. The results showed: (1) all 21st century skills consisting of problem solving, critical thinking, creativity, collaboration, communication, and digital literacy were at a low level of maturity; (2) the difference in the level of maturity experienced by teachers and students is quite significant in all competencies. Currently, 21st century skills in managing and following learning in vocational education must be strengthened again. Various training and mentoring for teachers and students should also be improved.

An industrial company that specializes in plastics, with the basic ingredients of PolyEthylene Terephthalate, PolyPropylene, and Hight Impact Polystyrene, the product is a plastic plate that is produced through the operation of the Extruder machine. Total Productive Maintenance (TPM) is one method of analyzing a machine and will help research the effectiveness of a machine with the help of other methods such as Overall Equipment Effectiveness (OEE) and Failure Mode and Effect Analysis (FMEA). Based on the quantitative analysis of the OEE calculation, the OEE value of the Extruder 1 GW-350 machine is obtained with an average calculation of 79.35%. Based on qualitative analysis using FMEA, the RPN failure mode score on the Extruder 1 GW-350 engine was obtained. The highest RPN value is the printer is unstable (die) at 240.

Apply the values of huma betang (family and know each other), belum bahadat (behave politely), hapakat basara (consensus for consensus), handep (mutual cooperation), and not yet full of hinje simpei (live in harmony and peace) in the Project Based Learning learning method (PjBL). The purpose of this research is to find out how students’ character development based on local wisdom uses the Problem Based Learning model. This research is a type of field research, qualitative research. The research subjects were students of class X IPS 2 at SMAN-1 Jabiren. The instrument used in this research is the researcher himself. The results of the study stated that with the PjBL method the characteristics of tolerance, curiosity, activeness, openness to input, communication, respecting achievements and opinions of friends, accepting differences of opinion, and respecting teachers are characteristics that develop significantly. Character education in the world of education, both primary, secondary, and even higher education must be well integrated.

Penelitian ini bertujuan untuk mengetahui pengaruh kompetensi karyawan terhadap kepuasan pelanggan bengkel manufaktur di Kota Serang. Metode penelitian ini menggunakan metode penelitian kuantitatif. Sampling yang digunakan berjumlah 27 orang dari 6 Bengkel Manufaktur yang ada di Kota Serang. Teknik pengambilan data yang digunakan adalah observasi, wawancara dan penyebaran angket kuisioner. Teknik pengolahan data dilakukan dengan menggunakan uji koefisien korelasi uji koefisien determinasi dan uji regresi sederhana. Hasil pengujian koefisien korelasi menunjukkan nilai hasil pearson correlation sebesar 0.870 dimana nilai tersebut berarti terdapat pengaruh antara kompetensi karyawan terhadap kepuasan pelanggan bengkel manufaktur di Kota Serang. Hasil pengujian koefisien determinasi Rsquare adalah kompetensi karyawan mempengaruhi tingkat kepuasan pelanggan hingga 75,7% dan sisanya dipengaruhi oleh variabel lain diluar penelitian ini angka ini menujukan bahwa pengaruh kompetensi karyawan lebih dominan dibandingkan faktor lain. Hasil pengujian persamaan regresi menunjukkan bahwa ketika kompetensi karyawan ditingkatkan maka kepuasan pelanggan dapat meningkat sebesar 57,6%. Sehingga arah hubungan antara kompetensi karyawan bengkel manufaktur di kota serang terhadap kepuasan pelanggan adalah positif searah. Oleh karena itu, berdasarkan hasil penelitian ini dapat menjadi landasan pengusaha bengkel manufaktur di Kota Serang untuk meningkatkan kualitas kompetensi pegawainya.
