plementasikan pada aplikasi skrining berbasis web. Dataset disusun ke dalam data latih, validasi, dan uji, kemudian citra diproses melalui penyesuaian ukuran 224×224, normalisasi, serta augmentasi pada data latih. Model dibangun menggunakan arsitektur MobileNetV3 Small dengan keluaran tiga kelas, yaitu Normal, Benign, dan Malignant. Sistem juga menerapkan validasi input untuk memastikan prediksi hanya dilakukan pada citra jaringan payudara sebelum proses inferensi. Hasil pengujian pada 300 data uji menunjukkan akurasi sebesar 88,00% dengan performa per kelas yang bervariasi, di mana kesalahan klasifikasi masih terjadi pada kelas-kelas yang memiliki kemiripan ciri visual. Hasil ini menunjukkan CNN efektif untuk mendukung skrining awal kanker payudara dan dapat ditingkatkan melalui penambahan data serta optimasi pelatihan pada penelitian selanjutnya
Abstract:This study discusses the design and construction of a corn sheller with a capacity of 80 kg/hour using an internal combustion engine . A corn sheller is a machine that functions to shell corn to separate the corn kernels…
from the corn cobs. In Indonesia, corn is available in abundance in rural areas, especially during the harvest season. In the production process, generally, during the shelling process, many farmers still use the shelling method by hand or using simple tools, which takes quite a long time. The reason people still use the shelling method by hand or using tools is because the price of the machine is too expensive and they are not even aware of the existence of a corn shelling machine. This corn shelling machine with a 5.5 HP internal combustion engine is a tool designed to speed up and simplify the corn shelling process efficiently and produce a fairly large production capacity of 80 kg / hour. To extend the service life of this corn shelling machine, maintenance and cleanliness should be carried out so that the machine can operate optimally without problems. Safety also needs to be considered to avoid unexpected work accidents.

emen proyek di lingkungan perguruan tinggi masih lebih berfokus pada aspek perencanaan dan pelaksanaan dibandingkan evaluasi proyek sebagai bagian penting dalam siklus manajemen proyek. Penelitian ini bertujuan untuk menganalisis peran Project Management Framework (PMF) dalam memperkuat kompetensi evaluasi proyek mahasiswa berdasarkan temuan-temuan penelitian terdahulu. Penelitian menggunakan metode studi literatur dengan pendekatan kualitatif deskriptif. Data diperoleh dari artikel jurnal nasional dan internasional, buku, serta dokumen ilmiah yang relevan mengenai PMF, evaluasi proyek, dan pengembangan kompetensi mahasiswa yang diterbitkan pada rentang tahun 2020–2025. Analisis dilakukan melalui proses identifikasi, seleksi, pengelompokan, dan sintesis temuan dari berbagai sumber literatur. Hasil kajian menunjukkan bahwa penerapan PMF berkontribusi dalam meningkatkan kemampuan mahasiswa dalam perencanaan proyek, pengendalian pelaksanaan, manajemen risiko, pelaporan, serta evaluasi proyek secara sistematis. Selain itu, integrasi aspek evaluasi dalam PMF mendorong terbentuknya budaya pembelajaran organisasi dan pengambilan keputusan berbasis data pada organisasi kemahasiswaan. Kajian ini menegaskan bahwa PMF dapat menjadi kerangka yang efektif dalam pengembangan kompetensi evaluasi proyek mahasiswa dan dapat diadaptasi dalam berbagai program pelatihan organisasi kemahasiswaan di perguruan tinggi.

Medan City Employment Service. The author limits the problem only to the effect of stress and work motivation on employee performance at the Medan City Employment Agency. Formulation of the problem whether work stress and work motivation affect employee performance at the Medan City Employment Agency, the population in this study totaled 58 people as the sample. The type of this research is quantitative research, with secondary data and distributing questionnaires to respondents as a data source. The data analysis method used is multiple linear regression analysis, hypothesis testing is done by Partial Test (t), Simultaneous Test (F) and Determination Coefficient Test (R2). The results of this study are Y = 0.550 + 0.447 X1 + 0.398 X2. The stress variable has a partial effect on employee performance. This can be seen from the significant value of 0.001 <0.05 and the t-count value of 3.543 > t-table 1.673. The motivation variable has a partial effect on employee performance, this can be seen from the significant value of 0.002 <0.05 and the t-count value of 3.225 > t-table 1.673, the hypothesis is accepted. The variables of stress and work motivation simultaneously have a positive and significant effect on employee performance. This can be seen from the resulting sig value of 0.000 <0.05 and the Fcount value of 34.156 while Ftable is 3.17 so Fcount > Ftable. Based on the test results of the coefficient of determination (R2) it is known that the R square value is 0.554 which means that the influence of stress and motivation variables on performance variables is 55.4%. It means having a relationship that is not too strong. While the remaining 44.6% is caused by other factors outside the research.
Abstract:This study aims to determine the effect of Job Satisfaction and Work Climate on Work Enthusiasm at the Medan City Umkm Cooperative Service. The test method used is sampling testing, the number of tests in this review is…
35 respondents taken from the population. seen from the F test obtained Tcount 14.405 > Ftable 3.285 with sig 0.000 <α 0.05, indicating that H0 is rejected and H1 is recognized, which means job satisfaction and work climate together have a significant effect on the variable morale. Judging from the results of the t test, it is very clear that the tcount of the morale variable is 3.181 greater than the Ftable of 1.692 with a possible t of 0.003 which means it is more significant by 0.05 on the morale variable. the variable of job satisfaction is seen from the variable of work enthusiasm. on the work climate variable, a tcount of 4.363 is greater than a ttable of 1.692 with a probability of sig 0.000 which is imperfect with the furthest level of importance reaching 0.05, so that the work climate variable is more or less visible than the work spirit variable. The Adjusted R Square value obtained means 0.441, this figure indicates that 44.1% of morale (reliable variable) can be explained by job satisfaction and work climate.

ion of the organization. set out, and to create work motivation to achieve high performance and loyalty to the work of employees. The aim of this study was to know whether compensation and motivation at work affect performance. This study is a quantitative study, with a sample of 35 employees, with the results concluding that pay and work motivation have a significant effect in part on performance, which is highlighted by table t counts > t, after the test results, it is concluded that salary and work motivation have a simultaneous effect, this is shown by the calculated value F > table F. Wage and motivation work also provides almost all the variance values of the performance variable, i.e. 87.9%. Based on the research results, the author suggests that leaders should care or develop policies related to compensation or ways to motivate employees. can increase employee loyalty and work capacity so it has a positive impact on performance
Abstract:This study aims to determine the significant effect of the use of the inshot-assisted inquiry learning model using the main material of work and energy in class X MIPA, even semester, Gajah Mada Mandiri Private High School,…
ol, Medan, Academic Year 2022/2023. This kind of research is basically experimental. All students of class X MIPA, even semester, Gajah Mada Mandiri Private High School, Medan from both classes constitute the majority of the population in the essay. Cluster random sampling was used to collect samples, with X MIPA1 and X MIPA2 acting as the experimental and control groups, respectively, with a total of 32 participants each and a teaching model that emphasizes in-depth learning with short lessons. The instrument used in this study was an essay test with approximately 10 validated topics. Data analysis of Lhitung-Ltabel and Fhitung-Ftabel showed that both data sets had a normal and homogeneous distribution. Analysis of two similar government agencies will be carried out next. The results of both classes were normally and uniformly distributed. Because tcount > ttable, the results of the one-tailed t-test for alpha = 0.05 and dk 62 produced tcount = 21.27 and ttable 1.99. This shows that there are significant benefits from using interdisciplinary learning with an inquiry model to support the student process in semester X of Mathematics and Natural Sciences in the academic year 2022/2023.
