Abstract

Rejuvenation is the replacement of new unproductive plant with new plants that are more productive and profitable. In the cultivation of oil palm there are several alternative models of rejuvenation that can be applied including conventional rejuvenation, underplanting rejuvenation and conventional rejuvenation with intercropping. This research was conducted in the Rambutan PTP. Nusantara III (Company). The time of the study was carried out in February to July 2019. This research was conducted using descriptive analysis method, namely by collecting primary data and secondary data. Primary data, each data for conventional rejuvenation and underplanting model that is. Morfological observation (midrib) and secondary data. Each data for conventional rejuvenation and underplanting model viz, insert (2017, 2018, 2019) and interest and Fruit Calculation Data. The results showed that conventional rejuvenation techniques at the time before planting carried out include several stages including the felling of old plants and tillage until the area was ready for replanting so as to reduce the level of pest infestation and provide ideal soil for plant growth in the field. Mean wile for underplanting planting system places the insertion height ths hetat occurs in underplanting planting system which replace the disruption of young plant growth after the undisciplined implementation of underplanting technique. Poisoning of old plants is late and results in late mutation from TBM to TM ieless interest and fruit in the underplanting technique.

Abstract

Keberhasilan pembangunan perkebunan kelapa sawit diawali dari penyediaan bibit yang standar sesuai dengan kriteria yang dikeluarkan oleh produsen kecambah. Nitrogen (N) adalah salah satu unsur hara yang sangat menentukan pertumbuhan kelapa sawit (Elaeis guinensis Jacq). Sumber pupuk nitrogen untuk pemupukan kelapa sawit bervariasi dari sumber alam maupun sintetik. Harga pupuk nitrogen yang terus meningkat menjadi dasar untuk melakukan penelitian ini, sehingga akan diperoleh alternatif lain sebagai sumber pupuk N di pembibitan utama kelapa sawit. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh beberapa sumber pupuk nitrogen terhadap pertumbuhan bibit kelapa sawit (Elaeis guinensis jacq) di pembibitan utama. Metode yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) non faktorial dengan 5 taraf yaitu N1 (pupuk urea), N2 (pupuk ZA), N3 (Pupuk Organik Cair dari Azolla microphylla 60 ml/liter H2O), N4 (pupuk hijau dari Azolla micropylla (50 g/polybag) dan N5 (pupuk kompos dari Azolla microphylla 50 g/polybag). Jumlah ulangan sebanyak 5; dengan jumlah bibit/plot sebanyak 3, sehingga jumlah bibit yang digunakan seluruhnya adalah 60 bibit. Hasil penelitian menunjukkan bahwa beberapa sumber pupuk N tidak berpengaruh nyata terhadap tinggi tanaman (cm) pada minggu 2 dan 4 setelah aplikasi perlakuan, tetapi berpengaruh nyata pada Minggu ke 6, 8, 10 dan 12 setelah aplikasi perlakuan, dengan bibit tertinggi pada N4 di umur 12 Minggu setelah aplikasi. Beberapa sumber pupuk N tidak berpengaruh nyata terhadap jumlah daun umur 2 dan 4 minggu setelah aplikasi, dan berpengaruh nyata pada umur 6, 8, 10 dan 12 minggu setelah aplikasi, dengan jumlah daun tertinggi pada N3, tetapi tidak berbeda nyata dengan N4. Beberapa sumber pupuk Nitrogen tidak berpengaruh nyata terhadap lingkar batang umur 2, 4, 6, 8 dan 12 minggu setelah aplikasi perlakuan, berpengaruh nyata terhadap berat basah dan berat kering akar pada umur 12 minggu setelah aplikasi dengan berat segar dan berat kering tertinggi pada N5 tetapi tidak berbeda nyata dengan N4 dan N3. Perlakuan tidak berpengaruh nyata terhadap Panjang akar. Kesimpulan dari penelitian ini adalah beberapa sumber pupuk nitrogen berpengaruh terhadap pertumbuhan kelapa sawit di pembibitan utama. Pupuk nitrogen yang bersumber dari Azolla microphylla dalam bentuk kompos, pupuk hijau dan POC berpengaruh sama baik terhadap jumlah daun, tinggi tanaman, berat basah dan kering akar. Azolla microphylla berpotensi digunakan sebagai alternatif pengganti pupuk ZA dan Urea pada kelapa sawit di pembibitan utama.

Abstract

Tanaman karet (Hevea brasiliensis) berasal dari negara Brazil. Pohon karet pertama kali hanya tumbuh di Amerika Selatan. Perkebunan karet di Indonesia mulai diperkenalkan sejak tahun 1864, yaitu sejak Hofland mendirikan perusahaan perkebunan karet di Tanah Panunukan dan Ciasem, Jawa Barat. Serangan yang diakibatkan oleh penyakit Pestalotiopsis sp. menunjukkan bercak cokelat pada daun karet dan adanya batas yang jelas antara bagian bercak dengan bagian daun yang masih sehat. Daun yang terinfeksi gugur sebelum waktunya. Umumnya yang terserang berat adalah tanaman karet yang sudah menghasilkan dan tidak terawat. Penelitian bertujuan untuk mengetahuai tingkat resistensi beberapa klon introduksi yaitu PB 217, PB 260, PB 330, PB 340, RRIC 100, IRR 220 dan GT 1 terhadap penyakit gugur daun yaitu Pestalotiopsis sp. Penelitian dilakukan di Laboratorim Proteksi Tanaman Balai Penelitian Sungai Putih menggunakan Rancangan Acak Lengkap (RAL) non faktorial. Hasil penelitian menunjukkan bahwa pada pengamatan 8 hari setelah inokulasi (hsi) intensitas serangan tertinggi ditemukan pada klon PB 217 dan GT 1 yaitu sebesar 89,9%6 dan 89,96%, sedangkan intensitas serangan terendah terdapat pada klon IRR 220 yaitu sebesar 81,64%.
