Abstract

Tandan kosong kelapa sawit merupakan limbah yang dihasilkan dalam industri minyak sawit serta memiliki kandungan unsur hara makro yang tinggi seperti N, P, K, Ca dan Mg, sehingga berpotensi untuk digunakan sebagai sumber nutrisi bagi tanaman kelapa sawit. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan tanaman kelapa sawit belum menghasilkan dengan pemberian kompos tandan kosong kelapa sawit. Penelitian ini dilaksanakan di perkebunan kelapa sawit belum menghasilkan PT. Padasa Enam Utama Teluk Dalam Kecamatan Air Batu, Asahan, Sumatera Utara. Penelitian ini menggunakan metode rancangan acak kelompok non faktorial tiga ulangan dengan dosis kompos tandang kosong kelapa sawit sebagai perlakuan. Hasil penelitian menunjukkan bahwa pemberian kompos TKKS sebanyak 30 kg/pohon mampu meningkatkan tinggi tanaman, jumlah pelepah, jumlah klorofil, panjang pelepah dan luas daun kelapa sawit belum menghasilkan dibandingkan dengan tanpa pemberian kompos TKKS berturut-turut sebesar 21.81%, 34.18%, 66.39%, 15.72%, dan 22.25%.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh ketahanan beberapa varietas kedelai (Glycine max) dan pemupukan nitrogen terhadap penyakit karat daun kedelai (P. pachyirhizi). Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Islam Sumatera Utara, Kelurahan Gedung Johor, Kecamatan Medan Johor, Kota Medan, Provinsi Sumatera Utara dengan ketinggian tempat  25 mdpl serta topografi datar. Dilaksanakan pada bulan Mei 2021 sampai dengan bulan September 2021. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor perlakuan yaitu varietas tanaman kedelai dan pupuk Nitrogen. Faktor pertama yaitu: jenis varietas terdiri dari 4 taraf yaitu : V1 (Anjasmoro), V2 (Grobogan), V3 (Dega 1), dan V4 (Dering 1). Faktor kedua yaitu: pupuk Nitrogen terdiri dari 3 taraf yaitu : N1 (4,4 g/plot), N2 (14,4 g/plot), dan N3 (24,4 g/plot). Hasil penelitian menunjukkan Jenis varietas berpengaruh nyata terhadap intensitas penyakit karat daun, persentase tanaman terserang, produksi per plot dan bobot biji 100 butir. Pemberian pupuk N berpengaruh nyata terhadap intensitas penyakit dan persentase tanaman terserang. Interaksi antara jenis varietas kemudian pemupukan N berpengaruh nyata terhadap intensitas penyakit karat daun

Abstract

This study aims to analyze the differences in the production of rubber planting in swamp land and land in North Sumatra. Rubber plants are one of the mainstay commodities in North Sumatra Province along with oil palm plantations. It's just that lately many rubber farmers are converting rubber land to oil palm land. This causes the production and price of rubber commodities to fluctuate. One way to prevent this is to plant rubber in swampy soil. This research uses descriptive qualitative research. Collecting data by observation, interviews, document analysis, literature study, especially using previous research data. The results of this study indicate that there has been a decline in rubber production during the last ten years due to the conversion of rubber land to oil palm land whose main consideration is economic motives, both the increasing price of palm oil and decreasing rubber prices. It's just that, at the same time, rubber plantations have started in swamps that were previously untouched. However, the results are not quite satisfactory compared to rubber plants in dry land. Further research is needed on the factors that influence it and solutions to these problems

Abstract

This study aims to analyze the conversion of rubber land to oil palm and its effect on production in North Sumatra. Today many rubber farmers are turning their land into oil palm plantations. So that the famous commodity from North Sumatra, namely, palm oil, is no longer rubber. Whereas previously the rubber plant (Hevea brasiliensis) as a plantation plant that was integrated with the culture of the people of North Sumatra Province had environmentally friendly properties. This study uses descriptive qualitative research methods. Data were collected by observation, interviews, literature study, and document analysis. The results show that smallholder rubber plantations have been the mainstay of the economy of North Sumatra Province since a century ago. Although there has been a change from Rubber Land to Palm Oil Land, currently North Sumatra accounts for 33% of the total national natural rubber production. North Sumatra is the second largest natural rubber producer after South Sumatra.
