ABSTRAK Kelapa sawit merupakan tanaman perkebunan yang memegang peranan penting dalam industri pangan. Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

<h1>Spodoptera litura F. is one of the important pests in Horticulture commodities which can cause damage 80% and up to 100%. Karamunting (Melastome malabathricum) is a wild plant that grows in Tarakan City. This plant is known to contain secondary metabolites which are thought to have the potential to control pests. This study aims to determine the potential of Karamunting extract as a botanical insecticide material to control armyworms. This study uses a completely randomized design (CRD) method with 1 treatment factor, namely the concentration of Karamunting leaf extract. Potential extracts as botanical insecticides were tested by dye method using 4 concentrations, namely 0 (control); 500; 1000; 2000; 4000; and 8000 ppm. The results showed that Karamunting leaf extract was able to control armyworm pests. Giving extracts of 8000 ppm (P5) in feed caused the highest decrease in eating activity up to 41,2%, larval mortality up to 85%, and the highest mortality rate after 7 days of observation. Decreased feeding activity and larval mortality were thought to be influenced by the presence of phenol compounds, fatty acids, terpenoids, sterols and alkaloids identified in the extract. Thus, Karamunting leaf extract has the potential to be developed as an active ingredient in botanical insecticides to control armyworm.<strong></strong></h1>

Field experiment was conducted at National Horticultural Research Institute (NIHORT), Mbato Sub-station, Okigwe, Imo State, South-eastern Nigeria in the 2012 and 2013 cropping seasons to establish the most appropriate time to introduce component crops in cocoyam/cowpea mixture. Five different planting schemes (two and four weeks before, two and four weeks after and same day) and two cowpea genotypes (climbing Akidienu and erect IT97K-499-35) were used. The component crops were grown in monocultures to assess the productivity of the systems. The experimental design used was a completely randomized design with three replicates. Growth and yield of cocoyam and the cowpea genotypes increased significantly (P<0.05) when either of the component crops was planted earlier than the other. Intercropping reduced significantly (P<0.05) cocoyam yield by 0.7 − 74% in IT97K-499-35 and 22 − 80% in Akidienu. Sowing the cowpea genotypes the same day or before cocoyam resulted in over-yielding of cowpea, whereas sowing Akidienu and IT97K-499-35 after cocoyam caused pod yield reductions of 64% − 73% and 32% − 59% on average, respectively. Cocoyam planted two weeks before IT97K-499-35 produced more satisfactory yields of the intercrops than the other planting schedules with LER, LEC and ATER of 2.15, 1.03 and 1.57, respectively.
