“…Bioinfeksida oleh virus patogen serangga (VPS) dianggap sangat efektif dalam membasmi hama. VPS bisa bertahan di alam sangat lama dan dapat menularkan baik secara horizontal maupun vertikal [4]. VPS sengaja diberikan pada tanaman yang terserang hama, sehingga hama yang mengkonsumsinya akan terinfeksi dan dapat menularkan melalui kontak secara langsung pada hama rentan.…”

Pada artikel ini membahas model predator- prey yang terdiri dari dua predator dan satu prey dimana terdapat populasi prey terinfeksi dan kompetisi antara dua populasi predator, baik kompetisi intraspesifik ataupun kompetisi interspesifik, untuk memberikan pemahaman tentang dinamika sistem ekologi yang lebih kompleks secara matematis dengan menggunakan pemodelan sistem persamaan diferensial. Dilakukan analisis perilaku dinamis pada sistem, yang menunjukkan terdapat sembilan titik ekuilibrium. Titik ekuilibrium kepunahan selalu tidak stabil dan delapan titik ekuilibrium lainnya stabil asimtotik lokal dengan beberapa kondisi. Dilakukan simulasi numerik untuk mendukung hasil analitik. Diberikan diagram bifurkasi dengan menggunakan MatCont untuk menganalisis kestabilan sistem. Dengan menvariasikan parameter tingkat penyebaran penyakit, diperoleh hasil adanya bifurkasi transkritikal pada sistem. Kata kunci: model predator- prey, kestabilan lokal, bifurkasi

“…Fertilization can increase corn yields both qualitatively and quantitatively. This is because fertilization can increase the availability of nutrients, plant health and suppress disease development (Prahasta, 2009;Samsudin, 2016;Departemen Pertanian, 2019;Suswati et al, 2022;Azwana & Sihotang, 2023). Coconut water is a plant product that can be used to increase plant growth.…”

The aims ofthis research is to determine the response of growth and production of sweet corn (Zea Mays Saccharata Strurt) to the application of liquid organic fertilizer coconut water and tea waste compost. The research cobducted in Trial Garden of Agriculture Faculty of Medan Area University, Kolam Street no 1 Medan Estate with height 22 m above sea level. Plat topografi and alluvial soil type was done since June up to September 2018. The research is using Random Designing Group Factorial with two factors, such as coconut water POC (K0 = Control (purn); K1 = coconut water POC 50 ml/L; K2 = coconut water POC 100 ml/L; K3 = coconut water POC 150 ml/L), and the giving factors of tea pulp compost (K0 = Control (purn); K1 = tea pulp compost 5 Ton/Ha; K2 = tea pulp compost 10 Ton/Ha; K3 = tea pulp compost 15 Ton/Ha). Repeatedly twice. Parameter which observed are the height of the plant, leaf amount, diameter of the stem, the sample each plot of plant production, plant production each plot. The result of this research is two show that the giving of coconut water POC is not really influencing to the treatment and giving of the tea pulp compost to the treatment and giving of the tea pulp compost is really influencing to the height of the plant, the sample of plant production each plot, plant production each plot but not really influence to the leaf amount and diameter of stem as well as combination among coconut water POC and tea pulp compost is not influencing to all treatments.

“…One of the natural enemies of S. litura that has the potential to be developed as a biological control agent is Spodoptera litura Nucleopolyhedrovirus (SlNPV) which has high virulence against S. litura larvae. Samsudin [3] reported that two SlNPV isolates namely isolates B01 and B02 with a dose of 1.5 x 10 12 PIBs/ha can reduce the population of S. litura between 90-94% at 6 days after application. Besides, SlNPV symptoms were also found in the pupa and imago of S. litura [4].…”

Spodoptera litura F. is a new pest that potentially becomes a serious pest threatening palm oil industry. The control can be carried out using biological control agents S.litura Nucleopolyhedrovirus (SlNPV). Molecular approach using polymerase chain reaction (PCR) has been used to characterize the SlNPV isolate. The aim of this study was to determine the molecular characteristics of SlNPV Labuhan Batu isolate based on DNA sequence analysis. The NPV isolate was collected from oil palm plantation Negeri Lama Estate Group, PT. Hari sawit Jaya, Asian Agri, Labuhan Batu. The SlNPV DNA extraction was conducted using the DNA gSYNC kit. The amplification of SlNPV DNA was done by specific primers with oligonucleotide sequences forward 5′-ACGTTACGATCTAGATCC-3′ and reverse 5′-AACGTTAGACAGACATAT-3′ with ±700bp of amplicon. Homology and phylogeny characteristics were used to determine the relationship of SlNPV isolate from Labuhan Batu to NPV from other countries were reported in the GeneBank of National Center for Biotechnology Information (NCBI). The results showed that SlNPV isolate from Labuhan Batu had the closest related to SlNPV from Australia, SliNPV from Canada and SlNPV from China, with the similarity percentage 100%, 96% and 90% respectively. They belong to the same group as the NPVs that infected the Spodoptera genus.
