Abstract

ABSTRAK Kemiskinan merupakan salah satu persoalan mendasar, karena kemiskinan menyangkut pemenuhan kebutuhan yang paling mendasar dalam kehidupan dan kemiskinan merupakan masalah global karena kemiskinan merupakan masalah yang dihadapi banyak negara. Di samping itu kemiskinan juga berkaitan dengan keterbatasan lapangan pekerjaan dan biasanya mereka yang dikategorikan miskin (the poor) tidak memiliki pekerjaan (pengangguran), serta tingkat pendidikan dan kesehatan mereka pada umumnya tidak memadai. Tujuan dari penelitian ini adalah untuk mengetahui pengaplikasian metode exponential smoothing dalam peramalan jumlah penduduk miskin di Kabupaten Langkat tahun 2022-2025. Data yang digunakan adalah data tahunan dengan jenis data adalah data sekunder yang diperoleh dari Badan Pusat Statistik (BPS) Kabupaten Langkat. Metode peramalan yang tepat digunakan adalah double exponential smoothing, dengan menggunakan dua parameter yaitu ???? = 0,9 ???????????? ???? = 0,6. Hasil forecasting dengan metode ini pada tahun 2022-2024 berturut-turut 107.440, 109.020, 110.610, dan 112.200. Dalam hal ini hasil forecasting mengalami penaikan secara terus-menerus setiap tahunnya. Kata kunci : Kemiskinan, metode exponential smoothing, forecasting, stasioner, trend, musiman.

Abstract

The land certification program is a strategic step in supporting agrarian reform and ensuring legal certainty for the community. However, its implementation in Labuhanbatu Regency shows an imbalance in the number of certificates issued between sub-districts. This study was conducted to determine whether there is a significant difference in the average number of land certificates issued in each sub-district in Labuhanbatu Regency between 2023 and 2024. The type of data used is sourced from secondary data obtained through the Central Statistics Agency of Labuhanbatu Regency analyzed quantitatively. The normality test that has been carried out shows that the 2023 data results are not normally distributed, so the Wilcoxon Signed Rank test is used as an alternative to the paired t-test. From the results of the analysis, the average issuance of land certificates in 2023 was 615.00 and in 2024 it was 463.78. With a Wilcoxon test significance value of 0.139> 0.05, it shows that there is no statistically significant difference between years. Thus, although there is a decrease in numbers, the change is not statistically significant. These results are expected to be used as evaluation material in planning a more even land certification policy in Labuhanbatu Regency. Program sertifikasi tanah adalah langkah strategis dalam mendukung reformasi agraria dan menjamin kepastian hukum bagi masyarakat. Namun, pelaksanaannya di Kabupaten Labuhanbatu menunjukkan adanya ketimpangan jumlah sertifikat yang diterbitkan antar kecamatan. Penelitian ini dilakukan bertujuan untuk mengetahui apakah terdapat perbedaan yang signifikan rata-rata jumlah sertifikat tanah yang diterbitkan di tiap kecamatan di Kabupaten Labuhanbatu antara tahun 2023 dan 2024. Jenis data yang digunakan adalah yang bersumber dari data sekunder diperoleh melalui Badan Pusat Statistik Kabupaten Labuhanbatu dianalisis secara kuantitatif. Uji normalitas yang telah dilakukan menunjukkan hasil data tahun 2023 tidak berdistribusi normal, sehingga digunakan uji Wilcoxon Signed Rank sebagai alternatif paired t-test. Dari hasil analisis rata-rata penerbitan sertifikat tanah tahun 2023 sebesar 615,00 dan tahun 2024 sebesar 463,78. Dengan nilai signifikansi uji Wilcoxon sebesar 0,139 > 0,05, menunjukkan tidak terdapat perbedaan yang signifikan secara statistik antar tahun. Dengan demikian, meskipun terdapat penurunan secara angka, perubahan tersebut tidak signifikan secara statistik. Hasil ini diharapkan menjadi bahan evaluasi dalam perencanaan kebijakan sertifikasi tanah yang lebih merata di Kabupaten Labuhanbatu.

Abstract

Karo Regency is recognized as one of the main citrus-producing regions in North Sumatra, contributing significantly to the local agricultural economy. However, citrus production in this area has fluctuated over the years, possibly due to variations in climatic conditions. This study aims to examine the extent to which climatic factors influence citrus production in Karo Regency. The analysis employed a multiple linear regression approach to identify the relationship between climatic variables and production outcomes. The research utilized secondary data obtained from relevant institutions, including citrus production records and climate data for the study period. Independent variables included temperature, humidity, rainfall, and the number of rainy days, while citrus production served as the dependent variable. The findings revealed that both jointly and individually, climatic factors had no significant effect on citrus production. The coefficient of determination (R²) of 0.211 indicates that only 21.1% of production variation is explained by the model. Consequently, future studies are encouraged to incorporate other determinants such as cultivation practices and farm management strategies
