Abstract

Peranan serangga sebagai hama menyebabkan kerugian bagi tanaman budidaya dan manusia. Terutama Setothosea asigna sebagai ulat pemakan daun tanaman kelapa sawit, sehingga pengendalian hama ini penting dilakukan, namun pedoman pengendalian yang selama ini di gunakan hanya berlandaskan pada jumlah larva di batas ambang ekonomi tanpa memperhatikan tipe instar larva Setothosea asigna yang menyerang tanaman. Penelitian ini bertujuan untuk mengetahui preferensi pakan stadia larva Setothosea asigna terhadap daun tanaman kelapa sawit (Elaeis guineensis Jacq.). Penelitian dilakukan di lahan percobaan Emplasmen PTPN IV unit laras. Metode yang digunakan dalam penelitian yaitu experimental design dan teknik observasi untuk pengambilan objek penelitian. Perlakuan dalam penelitian adalah memberikan pakan daun tanaman kelapa sawit dengan 2 waktu yaitu pukul 07:00 WIB dan pukul 19:00 WIB. Hasil pengamatan menunjukkan tingkat konsumsi paling tinggi di pagi hari dan malam hari terdapat pada instar 7 larva S. asigna, dan hasil analisis regresi linear sederhana menunjukkan bahwa, tipe instar berbanding lurus dan berpengaruh secara langsung (positif) terhadap jumlah pakan. Preferensi pakan stadia larva Setothosea asigna terhadap daun tanaman kelapa sawit (Elaeis guineensis Jacq.) lebih aktif pada malam hari serta tingkat konsumsi pakan yang paling tinggi baik pagi ataupun malam hari terdapat pada instar 7 dan hubungan antara instar stadia larva Setothosea asigna terhadap jumlah pakan daun tanaman kelapa sawit (Elaeis guineensis Jacq.) baik pada pagi hari ataupun malam hari yaitu berbanding lurus dan berpengaruh secara langsung.

Abstract

Kelapa sawit merupakan satu dari sekian banyak komoditas penyumbang terbesar bagi devisa negara. Pertumbuhan bibit kelapa sawit sangat ditentukan oleh ketersediaan unsur hara dengan pemanfaatan limbah organik seperti kulit pisang kepok dan urine domba. Hal tersebut akan mengurangi penggunaan pupuk kimia (anorganik) yang dapat menciptakan pertanian ramah lingkungan. Selain itu, berdasarkan refrensi yang penulis baca masih sangat jarang dijumpai penelitian mengenai pemanfaatan kulit pisang kepok menjadi pupuk organik cair terutama aplikasi pada pembibitan kelapa sawit. Penelitian ini memiliki tujuan untuk mengetahui respon pertumbuhan bibit kelapa sawit di tahap Pre-Nursery setelah diberikan kulit pisang kepok sebagai Pupuk Organik Cair (POC) dengan dosis yang berbeda. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) 1 faktorial. Faktornya adalah POC kulit pisang kepok yang terdiri dengan 4 taraf yaitu: Kontrol (A0), 50 ml (A1), 150 ml (A2), 300 ml (A3). Data dianalisis dengan menggunakan sidik ragam (analysis of variance) di lanjutkan Duncans Multiple Range Test dengan signifikan 5 %. Parameter yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, berat segar tajuk, berat kering tajuk, berat segar akar dan berat kering akar tanaman. Berdasarkan hasil dari penelitian ini bahwa pengaplikasian pupuk organik cair kulit pisang kepok tidak berpengaruh nyata terhadap respon pertumbuhan bibit kelapa sawit di tahap pre-nursery, namun bila berdasarkan data rataan, pengaplikasian 50 ml pupuk organik cair kulit pisang kepok mampu mendorong pertumbuhan bibit kelapa sawit pada tahap pre-nursery.

Prabowo W, Pratomo B, Irni J, Agustina N. A, Novita A. 2020. Application of dung and empty fruit bunch to elaeis guineensis jacq growth in pre nursery. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).In an effort to implement zero waste management in oil palm plantations, bunch ash which is a waste product from palm oil mills can be used as fertilizer for oil palm plants. This study aims to determine the growth of oil palm seedlings after being given different doses of dung from chicken and bunch ash fertilizer. This study used an experimental method with a factorial randomized block design (RBD). The first factor is chicken manure which consists of 4 levels, namely: Control (P0), 70 gr (P1), 140 gr (P2), 210 gr (P3) and the second factor is oil palm basket ash fertilizer which consists of 4 levels namely: Control (A0), 13 gr (A1), 26 gr (A2), 39 gr (A3). The data obtained were analyzed using analysis of variance (Analysis of Variance) with a significant 5%. If it has a significant effect, continue with the Duncan's Multiple Range Test (DMRT). Based on the results of the data analysis, it was found that the treatment of chicken manure did not have a significant effect on plant growth (shoot wet weight, shoot dry weight, root wet weight, root dry weight and root length), and the interaction did not significantly affect the growth of oil palm seedlings in pre nursery. Although some of the parameters tested did not show any statistical effect, the physical growth of oil palm seedlings produced seeds that still met the seed growth standards in the pre-nursery.

Abstract

Introduction: This study aims to determine the growth response of Mucuna bracteata cuttings to the concentration and duration of soaking shallot extract. Materials and Methods: This study used a factorial Randomized Block Design (RBD) with two factors, namely: shallot extract concentration (P) consists of 4 levels, include P0= untreated, P1= 10 ml, P2= 20 ml, P3= 30 ml, meanwhile the soaking time (Q) consists of 4 levels, such as Q0= momentarily dipping, Q1= 15 minutes, Q2= 30 minutes, Q3= 45 minutes. The data was processed by ANOVA and if significant, then further tested with Duncan Multiple Range Test (DMRT) at the rate of 5%. Results: The concentration of shallot extract, soaking time and their interaction had a very significant effect on the survival percentage of Mucuna bracteata D.C. cuttings. The highest survival percentage of cuttings of Mucuna bracteata on the effect of shallot extract concentration and soaking time was obtained in the P0Q0, P0Q1, and P3Q2 treatments after the lid was opened at 4 weeks after planting. In the number of leaves also had significant effect in the interaction of two factors

Abstract

Introduction: This study aims to obtain concentration of shallot extract (Allium cepa ) and growth regulators to increase growth of Mucuna bracteata. Mucuna is a land cover plant that must be planted in oil palm plantation areas. It is very important to be able to cover the planting area. Materials and Methods: This study used two factorial in randomized block design. The first was concentration of shallot extract per 100 ml distilled water consists of 4 levels, such as control (B0), 10 cc (B1), 20 cc (B2), 30 cc (B3) and the second was the auxins-plant growth regulator consists of 4 levels: Control (G0), 100 ppm (G1), 200 ppm (G2), 300 ppm (G3). Data analyzed with ANOVA with a significant 5% and continued with the DMRT using SAS version 9.1.3. Results: It was found that effect of concentration of shallot extract had a significant effect on survival percentage of Mucuna bracteata at a concentration of 10 cc (B2) after opening the lid at four weeks after planting (WAP) and did not change until 8 WAP. Likewise, the number of leaves at the control concentration (B0) at the age of 6 WAP, and a concentration of 10 cc (B1) at the age of 7-8 WAP. The concentration of growth regulators and their interactions did not significantly affect the survive percentage and number of leaves in Mucuna bracteata.
