| dc.description.abstract | Tingkat pengangguran terbuka (TPT) merupakan salah satu indikator untuk
meninjau kondisi ketenagakerjaan pada suatu wilayah di Indonesia. Indonesia
menjadi negara dengan tingkat pengangguran tertinggi di kawasan Asia Tenggara
pada tahun 2024. Namun, isu pengangguran menjadi permasalahan kompleks yang
melibatkan karakteristik kondisi tiap wilayah. Metode generalized LASSO melalui
penambahan matriks penalti ?? mampu memodelkan struktur data yang memiliki
pola spatio-temporal. Penelitian ini bertujuan mengidentifikasi pola spasial dan
temporal, peubah paling berpengaruh, serta mengevaluasi performa pendekatan
queen’s contiguity, k-nearest neighbor (KNN), dan a multidirectional ecotope
based algorithm (AMOEBA) menggunakan model spatio-temporal generalized
LASSO. Peubah yang digunakan, yakni tingkat partisipasi angkatan kerja (TPAK),
upah minimum provinsi (UMP), rata-rata lama sekolah (RLS), dan penanaman
modal dalam negeri (PMDN). Hasil penelitian menunjukkan bahwa pendekatan
KNN ?? = 2 menggunakan parameter penalti ?? optimum sebesar 0,0171
menghasilkan performa model terbaik dengan nilai RMSE dan MAE minimum,
menunjukkan bahwa pengelompokkan pengaruh sama terjadi paling kuat dalam
lingkup wilayah yang terlokalisasi. Pengaruh positif terkuat ditemukan pada RLS
di Kepulauan Riau tahun 2021 sedangkan pengaruh negatif terkuat ditemukan pada
TPAK di Bali tahun 2024. Hasil penelitian menunjukkan bahwa generalized
LASSO mampu menangkap dinamika pola spasial dan temporal dalam
mengidentifikasi peubah berpengaruh terhadap TPT di Indonesia | |
| dc.description.abstract | The open unemployment rate (TPT) is one indicator used to assess market
conditions in a region of Indonesia. Indonesia had the highest unemployment rate
in Southeast Asia in 2024. However, unemployment is a complex issue that
involves the specific characteristics of each region. The generalized LASSO
method, through the addition of a D-penalty matrix, can model data structures with
spatio-temporal patterns. This study aims to identify spatial and temporal patterns
and the most influential variables, as well as to evaluate the performance of the
queen’s contiguity, k-nearest neighbor (KNN), and a multidirectional ecotopebased algorithm (AMOEBA) approaches using the spatio-temporal generalized
LASSO model. The variables used were the labor force participation rate (TPAK),
the provincial minimum wage (UMP), the average years of schooling (RLS), and
domestic investment (PMDN). The results show that the KNN approach with k=2
and an optimal penalty parameter ? of 0.0171 yields the best model performance
with minimum RMSE and MAE values, indicating that the clustering of similar
influences is strongest within localized regions. The strongest positive effect was
found in RLS in the Riau Islands in 2021, while the strongest negative effect was
found in TPAK in Bali in 2024. The results indicate that generalized LASSO is
capable of capturing the dynamics of spatial and temporal patterns in identifying
variables that influence TPT in Indonesia | |
