Abstract

The study period is quite influential in the assessment of a university. The imbalance in the ratio of students to lecturers causes the quality of teaching and learning to decline, this is because one lecturer has to manage many students. Acquisition of accreditation scores and society's assumptions about higher education are also strongly influenced by the number of student graduations on time. Therefore, the prediction of the accuracy of the study period is needed as consideration for related parties to solve the problem of student learning delay. Sources of data in this study were taken from a database stored at the University of Surakarta, namely the Temporary Achievement Index with data of 209 instances and 5 attributes. The proposed method in this study is the Sequential Minimal Optimization algorithm. The validation method uses k-fold Cross-Validation with a value of K = 10. This method is compared with other methods such as naive Bayes, KNN, and Decision Tree. The results of this study, the proposed method can predict the accuracy of the study period quite well with the acquisition of accuracy of 88.52%. However, several other methods such as NaiveBayes obtained better accuracy of 90.91%, KNN of 91.86%, and Decision Tree of 96.65%. From the results of the comparison of these methods, the Decision Tree obtained the highest accuracy value. In future studies, researchers aim to enrich features in the prediction process. These features are related to student activities, such as student backgrounds, social activities, additional activities on campus and off-campus, and other aspects.

Abstract

The impact of the Covid-19 pandemic has forced the economic activity of the Indonesian population to decline drastically, which has an impact on the education funding process. Given these problems, it is necessary to develop a Decision-Making System to assist the selection process for KIP admissions for students who meet the requirements. The purpose of this research is that the provision of KIP can be right on target. For decision making, three stages are used with the method used, the first stage is the C-45 method for student priority decision making, the second stage is the Fuzzy MADM method, and the third stage is ranking according to the total quota. which is determined. The initial selection used the C-45 method with the variables of GPA, parents' income, achievements, parental dependents, and cases. The results of the C4.5 calculation show that the first priority is parental dependents with a Gain value of 0.007822696, followed by a GPA with a Gain value of -0.130011482, the third priority is Parents' Income with a Gain value of -0.702657067 and the last priority is an achievement. The results of the calculation are continued with Fuzzy MADM resulting in 5 rules used to determine student priorities (can) or not. The results achieved from 140 students who applied were accepted by 135 students who passed the initial stage, and out of 135 rankings, 70 students were determined to receive scholarships from the Government with the highest calculation score of 21 and the lowest of 14.4.

Abstract

Keripik kentang salah satu makanan ringan favorit berbentuk irisan tipis, digoreng/di-oven, kering dan renyah saat dimakan. Beberapa UKM di daerah alun-alun kidul kraton Kasunanan Surakarta setiap sore atau libur, menyajikan makanan ringan cepat saji (fast food) salah satunya french fries. French fries yang disajikan paling banyak diminati konsumen berbentuk potongan spiral. Meningkatnya permintaan pasar produksi tertentu, harus diimbangi teknologi sarana pendukungnya. Keadaan tersebut mendasari untuk melakukan perancangan mesin inovasi yang dapat membuat keripik dengan potongan model spiral. Dipasaran telah ada alat pemotong keripik model spiral tetapi dalam penggunaannya masih secara manual atau konvensional dengan menggunakan tenaga manusia. Rancang bangun ini bertujuan untuk membuat mesin pemotong keripik model spiral yang efektif dan efisien. Metode rancang bangun dimulai dengan tahapan menetapkan kebutuhan, mekanisme, pemilihan material, perancangan komponen, gambar design. Tahap pembuatan mesin mencakup gambar teknik/kerja, pemotongan bahan sesuai ukuran, pembubutan, pengelasan, perakitan dan uji unjuk kerja mesin untuk mengetahui hasil pembuatan mesin. Mesin pemotong keripik model spiral memiliki dimensi panjang 500 mm, lebar 150 mm dan tinggi 200 mm, menggunakan plat stainlesssteel dengan tebal 3 mm, berat 6 kg dan portable. Mesin berpengerak motor stepper Nema 23 dengan spesifikasi 12 Volt, 24 Watt, torsi 0,98 Nm dan kecepatan 100–500 rpm. Mata pisau yang digunakan memiliki dimensi 50x20 mm, dengan menggunakan kecepatan 100 rpm mesin mampu menghasilkan pemotongan keripik model spiral sebanyak 0,8 kg/menit. Kapasitas produksi mesin dibanding dengan alat pemotong kentang spiral berpenggerak tenaga tangan (manual) mesin pemotong keripik model spiral lebih efektif dan efisien.
