Abstract

Tanaman karet (Hevea brasiliensis) adalah salah satu komoditas perkebunan unggulan yang banyak dibudidayakan di daerah tropis, termasuk Indonesia. Tanaman ini dikenal karena menghasilkan lateks, bahan baku utama dalam industri karet alam yang digunakan untuk berbagai produk seperti ban, sarung tangan, dan komponen otomotif. Tujuan penelitian Untuk mengetahui apakah produksi karet di PTPN IV Kebun Rantauprapat maksimal akibat pengaruh curah hujan. Metode survei yang sesuai dengan penelitian mengenai pengaruh curah hujan terhadap produksi tanaman karet adalah metode survei berbasis data sekunder dan primer. Data sekunder dapat diperoleh dari catatan historis produksi lateks, curah hujan, dan jumlah hari hujan yang tersedia di PTPN IV Regional 1 Kebun Rantauprapat. Hasil penelitian menunjukkan bahwa curah hujan tidak memiliki pengaruh yang signifikan terhadap produksi lateks. Hubungan antara kedua variabel tergolong lemah dengan nilai R sebesar 0.263, yang hanya menjelaskan 6.9% variasi dalam produksi lateks, sementara 93.1% dipengaruhi oleh faktor lain yang tidak tercakup dalam model. Hasil uji ANOVA dan koefisien regresi yang tidak signifikan lebih lanjut memperkuat temuan ini, yang menunjukkan bahwa variabilitas dalam curah hujan tidak secara signifikan berkontribusi terhadap perubahan produksi lateks. Kata Kunci : Curah Hujan, Produksi Tanaman, Karet, PTPN IV Kebun Rantauprapat ================================================================================================= Rubber plants (Hevea brasiliensis) are one of the leading plantation commodities that are widely cultivated in tropical areas, including Indonesia. This plant is known for producing latex, the main raw material in the natural rubber industry used for various products such as tires, gloves, and automotive components. The purpose of the study was to determine whether rubber production at PTPN IV Kebun Rantauprapat was maximized due to the influence of rainfall. The survey method that is appropriate for research on the effect of rainfall on rubber plant production is a survey method based on secondary and primary data. Secondary data can be obtained from historical records of latex production, rainfall, and the number of rainy days available at PTPN IV Regional 1 Kebun Rantauprapat. The results of the study showed that rainfall did not have a significant effect on latex production. The relationship between the two variables was relatively weak with an R value of 0.263, which only explained 6.9% of the variation in latex production, while 93.1% was influenced by other factors not included in the model. The results of the ANOVA test and the insignificant regression coefficient further strengthened this finding, indicating that variability in rainfall did not significantly contribute to changes in latex production.
