Abstract

Classical quantile regression is global generalized parameter estimation results, spatial heterogeneity conditions cannot be captured by this model. The use of local models with spatial attribute can accommodate the characteristics between observation locations. The local quantile regression model is called the Geographically Weighted Quantile Regression (GWQR) model. Further testing of the effectiveness of this model is required by utilizing simulation data. This study uses simulated data generated with sample sizes uniformly distributed with intervals (0,1) contaminated with 5%, 10%, 15% outliers, with predictor variables (x=4) (β1,β2,β3,β4), and quantile sizes of 0.05, 0.25, 0.50, 0.75 and 0.95. Model effectiveness is measured based on Root Mean Square Error (RMSE). From the test, GWQR model can overcome the problem of outliers in simulated data up to the amount of outlier contamination of 15%, and spatial heterogeneity. The RMSE value is getting closer to 0 as the sample size and outliers increase. The test results explain that the 0.95 quantile produces the best parameter estimates compared to other quantiles.

Abstract

Regional economic disparities and fragmented inter-island linkages remain key challenges in East Nusa Tenggara (NTT), one of Indonesia’s archipelagic provinces with diverse resource endowments. This study analyzes the structure and dynamics of NTT’s regional economy by identifying its leading sectors through intersectoral linkage analysis, estimating the magnitudes of multiplier effects, and examining spillover effects across the province’s major islands. The research utilizes the 2016 Input–Output Table of NTT Province and the accumulated Gross Regional Domestic Product (GRDP) data of regencies and cities across the Timor, Flores, and Sumba islands for the 2016–2023 period. Analytical methods include linkage analysis, multiplier effect estimation, and the Vector Error Correction Model (VECM). The results show that agriculture, manufacturing, electricity, trade, and transportation constitute the leading sectors due to their strong forward and backward linkages. At the same time, agriculture and manufacturing also generate the largest multiplier effects. These sectors further create significant inter-island spillover effects, characterized by spread effects between Sumba–Timor, Sumba–Flores, and Timor–Sumba, and backwash effects between Timor–Flores and Flores–Sumba. The findings highlight that strengthening productive linkages in agriculture and manufacturing is vital for enhancing spatial equity and promoting inclusive regional growth. Conceptually, this study contributes to the literature by integrating intersectoral, multiplier, and spillover analyses to explain spatial economic interdependence in archipelagic regions and by offering practical policy implications for fostering sustainable inter-island integration in NTT Province.

Abstract

The concept of Entrepreneurship is needed for the community to increase farmers' income for the community so that a strong push is needed for the community to seize opportunities in the border areas of Indonesia and Timor Leste. The Melati Women Farmers Group of Haumeni Village became a threshing area in an effort to mobilize group members in developing Entrepreneurship through training in processing local products made from rice flour into other local foods to be made into local specialties which can later become regional souvenirs. For this reason, strong training is needed both from processing methods, how to utilize the technology used and how to manage the business in order to increase income and in the future can expand the scale of the business. The problem approach that will be formulated in developing Farmer Empowerment activities in North Bikomi District for the Haumeni Women Farmers Group is: Socialization, Scheduling and Training and Programs. The conclusion of the farmer group can increase knowledge in processing raw materials into processed foods that have high added value. Local processed food products have high economic value in increasing the profits of farmers and women's farmer groups from the production results which can later be sold either at their own outlets or through collaboration with shops or other kiosks

Abstract

Peralihan penggunaan pupuk anorganik ke organik yang ramah lingkungan terus diupayakan dengan pengoptimalan potensi petani di Kelompok Tani Rajawali, Desa Halibasar Kabupaten Malaka. Peralihan diupayakan dengan memanfaatkan limbah organik pertanian/peternakan di sekitar lingkungan pertanian untuk pembuatan pupuk kompos-biochar. Selama ini, penggunaan pupuk organik yang minim dikarenakan kurangnya sosialisasi dan rendahnya pengetahuan petani mengenai bahaya jangka panjang penggunaan pupuk anorganik. Permasalahan tersebut menjadi dasar untuk melakukan kegiatan pengabdian ini. Pengabdian dilaksanakan pada bulan Juni – Juli 2022, metode pengabdian yang digunakan adalah participatory action research yang mana seluruh anggota kelompok tani dan tim pengabdi terlibat langsung dalam setiap tahapan. Hasil pengabdian diperoleh bahwa anggota kelompok tani telah memahami dengan baik dampak jangka panjang perbandingan penggunaan pupuk anorganik dan organik, sehingga peralihan penggunaan pupuk organik siap diaplikasikan secara bertahap selain itu, anggota kelompok tani telah menguasai tahapan-tahapan pembuatan pupuk kompos-biochar yang dapat dilakukan secara mandiri. Penggunaan pupuk organik menjadi pendekatan yang berkelanjutan dalam meningkatkan produktivitas pertanian berbasis ramah lingkungan dengan memanfaatkan limbah pertanian/peternakan di lingkungan Halibasar.

Abstract

Penelitian ini bertujuan menerapkan metode Double Exponential Smoothing untuk memprediksi jumlah pelanggan air bersih di PDAM Tirta Cendana Kota Kefamenanu. Data yang digunakan berupa jumlah pelanggan bulanan dari Desember 2018 hingga Desember 2024. Analisis dilakukan melalui pola data, estimasi parameter, evaluasi model menggunakan Mean Absolute Deviation (MAD), serta prediksi pelanggan periode Januari hingga Juli 2025. Hasil penelitian menunjukkan bahwa data pelanggan memiliki pola tren meningkat, kombinasi parameter α dan β terbaik menghasilkan nilai MAPE 10,22% (kategori baik) dan MAD 32,78. Prediksi menunjukkan jumlah pelanggan PDAM akan terus meningkat hingga Juli 2025. Dengan demikian, metode Double Exponential Smoothing dapat digunakan sebagai alat bantu yang efektif dalam perencanaan distribusi air bersih di masa mendatang.

Abstract

Rendahnya partisipasi siswa melanjutkan pendidikan tinggi di Universitas Timor disebabkan oleh ketimpangan informasi terkait SNPMB, sehingga intervensi yang dilakukan oleh Universitas dengan mengoptimalkan kegiatan sosialisasi dan promosi. Program Studi (Prodi) dengan partisipasi peminat rendah adalah Program Studi Matematika. Oleh karena itu, dalam kegiatan sosialisasi dan promosi ini diberlakukannya pendekatan inovatif berbasis game edukatif dan interaksi langsung, yang dirancang untuk meningkatkan pemahaman siswa terhadap prospek studi bidang matematika serta menumbuhkan minat dan kepercayaan diri mereka dalam memilih program studi. Mitra PkM adalah Sekolah Menengah Atas (SMA) yang berada di wilayah Kabupaten Timor Tengah Utara, dan Kabupaten Timor Tengah Selatan. PkM dilaksanakan dengan metode participatory action research sehingga hasil yang diperoleh secara kuantitatif menunjukkan adanya peningkatan pemahaman siswa SMA terhadap informasi SNPMB Universitas Timor, tercermin dari hasil post test 72%. Terkhususnya Prodi Matematika mengalami peningkatan pendaftaran siswa baru sebesar sepuluh siswa dibandingkan periode sebelumnya.
