Abstract

Synthetic insecticides have detrimental effect to environment. Botanical insecticides are considered to be safer to the environment. Need seeds contain compounds with insecticidal properties. The aim of this study was to examine the effectiveness of neem seeds extract to control Diamondback moth (DBM). A series of neem seeds extract concentration (0.04 %, 0.08 %, 0.16 %, 0.32 %) and control (without neem extract) were tested on second instar larvae in oral test and contact test. The results showed that neem seeds extract have significant effect on the mortality of second instar DBM larvae 24-72 h after treatment in oral test and 72 h after treatment in contact test. In the oral test, the neem seeds extract significantly reduced feeding intensity of the larvae 42 h and 72 h after treatment. Subsequently, the extract also significantly reduced the moth emergence. The neem seeds with concentration 0.16 % effectively control DBM second instar larvae 72 h after treatment. Insektisida sintetis memiliki efek merugikan bagi lingkungan. Insektisida botani dianggap aman untuk lingkungan. Biji nimba mengandung senyawa dengan sifat insektisida. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas ekstrak biji nimba untuk mengendalikan ulat kobis Plutella xylostella. Serangkaian konsentrasi ekstrak biji nimba (0,04%, 0,08%, 0,16%, 0,32%) dan kontrol (tanpa ekstrak nimba) diuji pada larva instar kedua dengan uji pakan dan uji kontak. Hasil penelitian menunjukkan bahwa ekstrak biji nimba berpengaruh nyata terhadap mortalitas larva instar II 24-72 jam setelah perlakuan pada uji pakan dan 72 jam setelah perlakuan pada uji kontak. Pada uji pakan, ekstrak biji nimba secara nyata mengurangi intensitas makan larva 42 jam dan 72 jam setelah perlakuan. Selanjutnya, ekstrak juga secara nyata mengurangi munculnya ngengat. Ekstrak biji nimba dengan konsentrasi 0,16% efektif mengontrol ulat kobis instar kedua 72 jam setelah perlakuan.

Abstract

Coffee is a commodity with high value for export. Coffee bean borer (Hypothenemus hampei) is the main pest causing the decline in coffee production. Farmers still rely on chemical insecticides to control this pest. To reduce the negative impact of insecticides, entomopathogen Beauveria bassiana is applied. The research aimed to investigating the level of pathogenicity of B. bassiana in controlling H. hampei, and investigating the concentration with the highest level of pathogenicity of B. Bassiana against H. hampei. Laboratory research was arranged in one factor Completely Random Design (CRD). This research used 8 (eight) treatments namely KO: Aquades, Kk: Lamda Sihalothrin 25 EC (Chemical Insecticide), B1: 10 g / L B. bassiana cultivated in rice bran media, B2: 20 g / L B. bassiana cultivated in rice bran media, B3: 30 g / L B. bassiana cultivated in rice bran media, B4: 10 g / L B. bassiana grown on corn media, B5: 20 gL B. bassiana grown on corn and B6: 30 g / L B. bassiana grown on corn media. Each treatment used coffee beans infested with 20 H. hampei and repeated 4 (four) times. The result of the research showed that B. bassiana was able to kill H. hampei. The concentration that was able to cause the fastest mortality with a high level of pathogenicity based on the pathogenicity test of B. bassiana on H. hampei (percentage of mortality, total mortality time, and feeding capacity) was 30 g/L of B. bassiana cultivated in rice bran media.Key words: Beauveria bassiana, Hypothenemus hampei, chemical insecticide, coffee bean

Abstract

Oligo chitosan is a supplement that can increase growth, accelerate flowering, and increase productivity in several types of agricultural crops, rice and horticultural commodities. The findings of this study, encourage the authors, to further test the Oligo chitosan on the initial growth of the bulbs of Iles-iles. It is known, that Iles-iles (Amorphophallus muelleri Blume) or "Porang" is one type of tuber whose life cycle is quite long, has a slow-growing bulbil, especially in the dry season. This growth delay is caused in addition to genetic traits, also dry environmental conditions come into effect, so if entering the rainy season at a certain time span will soon show a good appearance of growth. Bulbil as a planting material, in order to grow immediately, it is necessary to strive to accelerate its growth, one of which is to use Oligo chitosan. In the cultivation of iles-iles the use of Oligo chitosan to accelerate bulbil growth has never been done. Technological innovations produced by BATAN, have the opportunity to be used in the development of crop cultivation made from tubers. This study aims to test Oligo chitosan to encourage the realization of early growth of bulbil, through the treatment of immersion time and the concentration of Oligo chitosan which is higher than previous experiments that the authors have done. The experiment was conducted in the rainy season of 2019/2020 in the experimental farm of the UPN "Veteran" Yogyakarta Wedomartani Faculty of Agriculture under a tree stand, using a Split Plot Randomized Completely Block Design (RCBD) with three replications. As the main plot is the soaking time of Oligo chitosan solution, consisting of three kinds, namely 2.5 hours (L1), 5 hours (L2), and 7.5 Hours (L3), and as a sub plot is the concentration of the solution consists of 3 stages, namely (5.0 ‰ (K1), 10 ‰ (K2), and 15 ‰ (K3) and one control (without Oligo chitosan). The data obtained were analyzed by Variance Analysis with 95% confidence level, and for the difference test the Duncan Multiple Range Test (DMRT) was used at the 5% level and the Orthogonal Contrast Test The results showed that soaking Oligo chitosan for 2.5 hours (L1) was sufficient to provide a better initial growth effect for Ilesiles bulbil, with a fairly high concentration of 15 ‰ (K3).Keywords: Oligochitosan, Iles-iles or Porang, bulbil, soaking and concentration

Abstract

This research is intended to answer the obstacles in the cultivation techniques of shallots, especially in overcoming the low quality of growth, which in turn affects the yield and production of onions. In this experiment, spraying three types of frequency and four kinds of oligo-chitosan concentrations was tried throughout the growing onion period. Oligo-chitosan as a supplement, is given to the onion plants periodically, in various concentrations, in three different types of oligo-chitosan spraying, which they are (F1) given to plants aged 15 DAP and 45 DAP; (F2) given to plants aged 15 DAP, 30 DAP, and 45 DAP; and (F3) given to plants aged 15 DAP, 25 DAP, 35 DAP, 45 DAP. The oligo-chitosan concentration consists of four kinds of concentration, consisting of 0 ‰ (K0) as a control, 1 ‰ (K1), 2 ‰ (K2) and 3 ‰ (K3). The experiment was carried out in the field using a polybag, with a completely randomized environmental design with a 95% accuracy level. To determine the effect of treatment on the quality of growth of shallots, diversity analysis was carried out. From preliminary observations, it shows that the onion bulb growing power as a seed is quite good, while the treatment using oligochitosan gives significant results on increasing plant vigor, compared to not using oligochitosan. As for further observations that at plant height, the number of leaves and the number of tillers up to 50 days after planting, although it does not show any real effect of the treatment that was tried, but it can be suspected that the more frequency treatment given oligo-chitosan, more gives a better chance of yield than a few frequencies, while an oligo-chitosan concentration of 1 ‰ is sufficient to improve the quality of plant growth, then it can be expected that F2K1 will give higher tuber yields.Keyword: shallot, oligo-chitosan spraying frequency, oligo-chitosan concentration
