Abstract

This research to the characteristics of the land suitability of coconut plantations in the Secanggang District. This research also analyzes the improvement efforts that need to be done in increasing the productivity of coconut plants and make maps of actual land suitability and potential land suitability of coconut plants in Secanggang District. As well as providing recommendations for fertilization on coconut plantations. This research was conducted using a survey method consisting of four stages of activity, namely preparation, main survey, soil analysis and data processing. It can be seen from the results of this study that the potential land suitability of coconut in Secanggang District is S3 f and n (marginally according to nutrient retention factors and nutrient availability) in the Village of Kepala Sungai, Tanjung Ibus, Karang Gading, Perkotaan and Telaga Jernih. S3 f (marginally according to nutrient retention factor) in Karang Anyar, Kebun Kelapa, Secanggang, Selotong, Pantai Gading, and Teluk Village. S2 w, f and n (enough according to the limiting factors of water availability, nutrient retention and nutrient availability) exist in Sei Ular and Hinai Kiri villages. The with improvement efforts to the limiting factor of nutrient retention by adding organic matter, the limiting factor of low nutrient availability is by fertilizing. After an effort has been made to evaluate the suitability of coconut land to S2 w with the limiting factor of water availability, namely rainfall, which is the main limiting factor in assessing land suitability because land improvements cannot be made.

Abstract

Mukhlis I.M, NIRM 01.02.18.027. Tingkat keberdayaan pekebun karet pola swadaya di Kecamatan Portibi Kabupaten Padang Lawas Utara. Penelitian ini bertujuan untuk mengkaji tingkat keberdayaan pekebun karet pola swadaya serta faktor-faktor yang memengaruhi tingkat keberdayaan pekebun karet pola swadaya. Penelitian ini dilakukan di Kecamatan Portibi Kabupaten Padang Lawas Utara dimulai pada bulan Februari 2022 s.d bulan Juni 2022. Populasi yang digunakan adalah Kecamatan Portibi dan sampel desa Gumarupu Lama, Padang Manjoir, Gunung Martua dan Gumarupu Baru dengan jumlah sampel 68 responden. Penelitian ini menggunakan metode pengkajian kuantitatif dengan skala liker’tdan uji regresi linear berganda yang telah diuji validitas dan realibilitasnya. Berdasarkan rekapitulasi nilai tingkat keberdayaan pekebun karet pola swadaya di Kecamatan Portibi Kabupaten Padang Lawas Utara tergolong sangat tinggi dengan nilai 80,9% dan termasuk kategori sangat berdaya.Berdasarkan uji simultan (F) peran penyuluh, sumber daya manusia, pengalaman pekebun, ekonomi produktif, luas lahan dan kelembagaan petani secara bersama-sama berpengaruh nyata terhadap tingkat keberdayaan pekebun karet pola swadaya di Kecamatan Portibi. Dan untuk uji parsial (t) faktor-faktor yang terdiri dari variabel bebas sumber daya manusia (X2), pengalaman pekebun (X3), ekonomi produktif (X4) dan luas lahan (X5) berpengaruh signifikan terhadap variabel terikat tingkat keberdayaan pekebun karet pola swadaya (Y).  Kata Kunci : Keberdayaan, Pekebun Pola Swadaya, Portibi

Abstract

This research aims to analyze the application of Good Agriculture Practices (GAP) to nutrient absorption in the leaves of Arabica coffee plants (Coffea arabica L.) in North Sumatra Province. Data analysis method is quantitative method. The data analysis technique used in this research is descriptive analysis technique to describe the data that has been collected through field surveys which include field observations, leaf sampling and laboratory analysis results to measure nutrient content. The results showed that the application of GAP, including good soil management, planned fertilization significantly increased nutrient uptake in the leaves. The GAP managed crops showed increased levels of phosphorus compared to those managed conventionally. The application of GAP therefore not only improves soil chemical characteristics, but also increases coffee plant productivity through optimizing nutrient uptake, which can contribute to the sustainability of coffee plantations in North Sumatra. Keywords: GAP, leaf nutrient absorption, arabica coffee, north sumatra
