Abstract

Tujuan dari penelitian ini adalah untuk mengetahui strategi pengelolaan pengembangan pariwisata Pantai Teluk Nipah dalam meningkatkan wisatawan di Pemerintah Daerah Kabupaten Lampung Selatan dan strategi pengelolaan sumber daya manusia pengembangan pariwisata di Kawasan Wisata Pantai Teluk Nipah. Lokasi penelitian ini adalah Pantai Teluk Nipah yang terletak di Desa Bulok Kecamatan Kalianda Kabupaten Lampung Selatan Propinsi Lampung. Jenis metode penelitian yang digunakan adalah penelitian yang menggunakan pendekatan kuantitatif menggunakan regresi linier berganda dengan data yang diperoleh dari masyarakat yang tinggal didaerah objek wisata Pantai Teluk Nipah. Berdasarkan hasil deskripsi kuesioner dapat diketahui bahwa pariwisata Pantai Teluk Nipah perlu dilakukan pengembangan pada sarana dan prasarana serta tata kelola pariwisata yang baik. Sarana dan prasarana yang dapat dikelola di destinasi pariwisata Pantai Teluk Nipah. Pada siteplan telah dirancang konsep keberlanjutan dengan menerapkan komponen pariwisata 4A, yaitu: Attraction (Perkuatan dan perbaikan objek-objek wisata dan atraksi), Accessibility (Perbaikan sarana dan prasarana di kawasan wisata), Amenity (Penyediaan sarana penunjang) dan Ancilliary (Penyiapan lembaga dalam pengelolaan dan pembinaan wisata). Fasilitas-fasilitas yang dirancang dalam kawasan wisata Pantai Teluk Nipah.

Abstract

This study aims to estimate the prevalence of Stunting and Wasting in Sumatra in 2022 using nonparametric regression methods, specifically the Nadaraya-Watson Kernel and Penalized Spline regression models. Both models were applied to assess the relationship between these two correlated response variables and various predictor variables, such as low birth weight, sanitary facilities, poor population, and exclusive breastfeeding. The results showed that the Nadaraya-Watson Kernel regression, particularly using the Gaussian kernel, provided the best fit with minimal prediction error, as indicated by its low Generalized Cross-Validation (GCV) value of 0.024 and high R-squared values (0.9992 for Stunting and 0.9995 for Wasting). In contrast, the Epanechnikov kernel and Biweight kernel produced higher GCV values (0.110 and 0.356, respectively), indicating less optimal performance. For the Penalized Spline model, optimal parameters were determined with a smoothing parameter λ of 5 and 3 knots, which balanced model flexibility and smoothness. This research underscores the potential of nonparametric regression techniques in capturing complex relationships in health data and provides insights for improving interventions aimed at addressing child malnutrition in Indonesia.
