Abstract

Algoritma clustering telah digunakan secara luas dalam menanganipermasalahan pengelompokan data mining, dengan meminimumkanjarak antar objek didalam cluster (intra-cluster) danmemaksimumkan jarak antar cluster (inter-cluster) sehinggamendapatkan kualitas clustering yang baik. Pengelompokan siswadalam suatu kelas biasanya dilakukan berdasarkan nomor induksiswa dan urutan nilai rata-rata semua mata pelajaran. Makalah inimengusulkan sistem pengelompokan siswa yang didasarkan ataskesamaan setiap mata pelajaran utama sehingga siswa yang memilikikemampuan diatas atau dibawah rata-rata dapat dilayani dengan baik.Pengelompokan siswa tersebut akan dianalisis dengan menggunakanmetode fuzzy subtractive clustering.

Abstract

Produsen melakukan pengelompokan berdasarkan usia dengan tujuan untuk mendapat informasi tentang perilaku pembelian pada kelompok usia tertentu. Penelitian ini bertujuan untuk mendapatkan informasi tentang minat berbelanja konsumen pada kelompok usia tertentu dengan menggunakan metode centroid. Penelitian ini dilakukan di salah satu toko mebel dan elektronik di Kabupaten Bulukumba dengan membagi 8 kelompok usia dan 4 jenis faktor yaitu faktor harga, lokasi, produk dan pelayanan. Jenis penelitian ini adalah penelitian survey dengan data primer yang dikumpulkan menggunakan kuesioner dengan jumlah sampel sebanyak 200 konsumen, selanjutnya data dianalisis menggunakan analisis klaster dengan metode centroid. Hasil penelitian menunjukkan bahwa minat konsumen pada toko yang diteliti terbagi atas 2 klaster. Pada Klaster pertama terdiri dari konsumen yang berusia 31-40 tahun dimana minat konsumen lebih besar pada faktor kualitas produk (37,31%) dan pelayanan (37,31%), sedangkan pada klaster kedua terdiri dari konsumen yang berusia 16-30 tahun dan berusia 41-55 tahun dengan minat konsumen lebih besar pada faktor harga (37,59%) dan lokasi(36,09%). Nilai kepadatan klaster yang diperoleh adalah 0,16

Abstract

The Academic Information System (SIAKAD) serves a pivotal function in enhancing both operational efficiency and the quality of academic services within higher education institutions, particularly amidst the accelerating shift toward digitalization in the education sector. Despite its strategic importance, the effectiveness of SIAKAD implementation is contingent upon the level of user satisfaction—most notably that of students—which remains insufficiently explored through analytical models capable of capturing intricate causal relationships. This study seeks to empirically examine the determinants of student satisfaction in utilizing SIAKAD by investigating the influence of system quality, information quality, and ease of use, with perceived usefulness positioned as a mediating construct. The research adopts the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach, which is methodologically appropriate for complex models involving latent variables and non-normally distributed data. The analysis is based on survey data collected from 128 active undergraduate students at Universitas Patompo. The empirical findings indicate that information quality exerts a significant direct influence on student satisfaction (β = 0.547; p < 0.001) and an additional indirect effect mediated by perceived usefulness (β = 0.268; p < 0.001). Conversely, system quality and ease of use demonstrate no statistically significant effects. The coefficient of determination values (R² = 0.706 for satisfaction; R² = 0.615 for perceived usefulness) reflect a strong predictive capability of the model. These results affirm that information quality is the most salient predictor of user satisfaction, underscoring the imperative to prioritize content enhancement as a strategic direction in the advancement of academic information systems within the higher education landscape.

Abstract

Penelitian ini membahas tentang pemodelan kepuasan mahasiswa terhadap layanan administrasi akademik di UIN Alauddin Makassar. Penelitian ini bertujuan untuk mengetahui model kepuasan mahasiswa terhadap layanan administrasi akademik di pusat layanan UIN Alauddin Makassar, serta mengetahui dimensi layanan apa saja yang signifikan memengaruhi mahasiswa UIN Alauddin Makassar. Metode penelitian yang digunakan yaitu analisis regresi logistik biner karena variabel respon dalam penelitian ini merupakan variabel biner dengan dua kategori yaitu puas dan tidak puas. Hasil penelitian menunjukkan bahwa berdasarkan hasil analisis data diperoleh bahwa variabel independen atau dimensi layanan yang signifikan berpengaruh terhadap kepuasan layanan administrasi akademik adalah variabel tangibles atau bukti fisik (X1) dengan nilai koefisien regresi sebesar 0,282 atau 28,2% dan variabel realibility (X2) dengan nilai koefisien regresi sebesar -0,167 atau 16,7%.

Abstract

This study aimed to find out the increase in students' creativity by using the Treffinger model assisted by color card media. This research used Class Action Research. The subject of the research was the VIII.3 grade students of Junior high school 1 Parepare. The data was collected using observation and tests. The research instrument was student activity observation sheets and test sheets for cycles 1 and 2. The data collected were analyzed by descriptive statistics technique. The result of the study showed that the implementation of the Treffinger model assisted by color card media can increase the mathematical creativity of the VIII.3 grade students of junior high school 1 Parepare. It can be indicated by the increase in the activity percentage with an average of 24.74% by cycle 1 was in the “fair” category (55.21%) to cycle 2 was in the “good” category (79.95%), and the increase of the achievement test was 24.53%. Keywords: color card, creativity, mathematics, Treffinger learning model. DOI: http://dx.doi.org/10.23960/jpmipa/v23i3.pp804-815
