Abstract

Tujuan penelitian ini yaitu menemukan kelompok siswa dan kelompokmata pelajaran yang homogen sehingga bisa memantau ataumengetahui kinerja akademik siswa. Langkah pertama yaitumentransformasi data dengan menggunakan normalisasi min-max.Setelah itu, diterapkan ? -Sim co-similarity untuk menghasilkanmatriks similaritas siswa (SS) dan similaritas pelajaran (SP). MasingmasingSS dan SP dikelompokan menggunakan algoritma k-meansclustering dan menggunakan Silhouette untuk menentukan banyaknyakelompok yang terbaik. Pada pengelompokkan SS diperoleh nilaiSilhouette terbesar yaitu 0,9755781 pada iterasi keempat yangmempartisi menjadi 4 cluster sebagai berikut 67 siswa pada cluster 1, 9siswa pada cluster 2, 45 siswa pada cluster 3 dan 43 siswa pada cluster4. Pada SP diperoleh nilai Silhouette terbesar yaitu 0,5756133 padaiterasi keempat yang mempartisi menjadi 2 cluster sebagai berikutBahasa Indonesia dan Bahasa Inggris pada cluster 1 dan Matematikadan IPA pada cluster 2.

Abstract

Tujuan penelitian ini adalah untuk menentukan model kasus Stunting dan Gizi Kurang dengan Regresi Poisson Generalized dan faktor-faktor yang berpengaruh terhadap kejadian tersebut. Analisis Data menggunakan Regresi Poisson Generalized karena untuk menangani masalah overdispersi pada data. Hasil yang diperoleh yaitu variabel yang berpengaruh signifikan terhadap kejadian Stunting 2018 adalah Jumlah penduduk miskin dan untuk kejadian Stunting 2019 adalah Persentase balita diberi ASI eksklusif dan Jumlah penduduk miskin. Variabel yang berpengaruh signifikan terhadap kejadian Gizi Kurang 2018 adalah Persentase balita diberi ASI eksklusif dan Jumlah bayi mendapatkan vitamin A dan untuk Gizi Kurang tahun 2019 adalah variabel Persentase balita diberi ASI eksklusif dan Persentase berat badan lahir rendah.

Abstract

This study aims to model stunting cases in children under five in Gorontalo city in 2018. In this model, it can be seen that the significant factors that affect stunting cases in children under five in Gorontalo city in 2018.  This study uses data on stunting cases in 9 (nine) districts in the city of Gorontalo and the factors that influence it. The research data were obtained from the Public Health in Gorontalo city. This study used one response variable, namely the number of cases of stunting and four predictor variables, namely number of toddlers who received exclusive breastfeeding, the percentage of low birth weight (LBW), the percentage toddlers who received complete basic immunization, and number of proper sanitation. The results obtained were the variables of number of toddlers who received exclusive breastfeeding and the percentage toddlers who received complete basic immunization which had a significant effect on stunting cases in children under five in the city of Gorontalo in 2018. This was indicated by the P-value of the variable for number of toddlers who received exclusive breastfeeding of 0.00283 and P-value of variable the percentage toddlers who get complete basic immunization is 0.06564.

Abstract

In this study, we propose an innovative method called the integrated GPCA MIGA, which integrates the multiple imputation genetic algorithm (MIGA) and generalized principal component analysis (GPCA) to perform missing value imputation and data dimensionality reduction simultaneously. The approximated original data produced by GPCA serves as the basis for MIGA to update missing values in the next iteration. At the same time, GPCA refines the low-dimensional representation using the latest imputation results from MIGA, thereby balancing the accuracy of missing value imputation and the stability of dimensionality reduction. The objective of this study is to evaluate the performance of the integrated GPCA-MIGA and analyze trends in human development at the district/city level in Indonesia. The findings of this study show that the integrated GPCA-MIGA effectively reduces the dimensionality of data containing missing values compared to other methods. The integrated GPCA-MIGA method was applied to human development data. The results were then visualized using a biplot, which revealed that human development trends in Jayawijaya from 2019 to 2022 indicate progress in school enrollment rates for ages 16–18 years.
