Abstract

Abstrak Objektif. Kehadiran gulma di perkebunan kelapa sawit dapat meningkatkan gangguan terhadap pertumbuhan tanaman, meningkatkan serangan hama dan penyakit, dan biaya pemeliharaan. Salah satu gulma penting pada perkebunan kelapa sawit adalah Imperata cylindrica atau alang-alang yang merupakan gulma dengan senyawa alelopati. Penelitian ini bertujuan untuk mengetahui effek keberadaan alang-alang terhadap pertumbuhan pembibitan awal kelapa sawit (Pre Nursery). Material and Metode. Alat dan bahan yang digunakan adalah cangkul, ayakan tanah, gembor, timbangan analitik, gelas ukur, blender, oven, kamera, penggaris dan alat tulis. Bahan yang digunakan adalah cairan ekstrak akar alang-alang, aquades, tanah/kompos, kecambah kelapa sawit, polibag ukuran 25cm x 15cm. Penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan, dan diulang sebanyak 9 kali dan dilakukan pada bulan september sampai dengan november 2019 di Kebun Praktek dan Penelitian (KP2) Akademi Komunitas Perkebunan Yogyakarta. Hasil. Ekstrak akar alang-alang pada konsentrasi 30% mampu menekan panjang akar 71%, konsentrasi 30% menekan berat segar bibit 40.17%, dan konsentrasi 30% dapat menekan 58.9% berat segar akar. Efek terhadap bobot kering bibit akibat pemberian alelopati pada konsentrasi 20% terjadi penekanan hingga 28.15% dan terhadap bobot kering akar pada konsentrasi 30% mampu menekan 60.31%. Kesimpulan. Alelopati ekstrak akar alang-alang tidak berpengaruh signifikan terhadap tinggi dan jumlah daun pada bibit. Namun pemberian ekstrak akar alang-alang signifikan menekan pertumbuhan akar bibit kelapa sawit, berat segar dan berat kering bibit dan akar.

Abstract

This paper aims to analyze the oil palm plantations of the people of Indonesia and Malaysia in the last 1998-2018 years to be able to analyze the broadness, production and productivity trends and compare the performance of people's oil palm plantations in both countries. This research was conducted based on official documents issued by the statistics agencies of Indonesia and Malaysia by comparing the trend of the area, production and productivity of people's oil palm plantations in the period 1998-2018, then the data processing was done by mathematical methods so that the performance of people's oil palm plantations from both countries could be known. Discussion is carried out from the results of data analysis with descriptive analytical methods. The results of this study are known that; The area of planting and harvesting people's oil palm plantations in Indonesia is higher than Malaysia and still allows it to continue to grow beyond the dominance of private plantations in Indonesia; CPO production of mustard coconut plantations.

Abstract

This study aims to determine the ability of tuba root extract and gadung tuber to control bagworms in oil palm plantations. The study used a two factorial completely randomized design. The first factor is the type of insecticide, namely tuba roots and gadung tubers. The second factor is the concentration of 0%, 2.5%, 5%, 10% and 15%. Differences between treatments were tested with Duncan's multiple distances at the 5% significance level. The results showed that tuba root extract and gadung tuber extract effectively controlled bagworm pests. At a concentration of 10%, tuba root extract and gadung tuber could control these pests. This study concludes that the use of tuba and gadung root extracts can be used to control bagworms in oil palm plantations. The results of this study are expected to be useful in developing botanical insecticides to control other plant pests.
