<p><em><strong>Potential of Maggot (Black Soldier Fly) as Animal Feed in Miri Village Kismantoro Wonogiri.</strong> </em>Cultivation of chicken and catfish was a field of business that was mostly carried out by residents of Miri Village, Kismantoro District, Wonogiri Regency. The high component of feed costs results in low profits. So far, farmers still rely on pellets as the main feed for their livestock. Alternative feeds in the form of Black Soldier Fly (BSF) larvae or maggot were well known to residents, but only a few residents had ever used maggot as feed. Residents had never received education and training on maggot cultivation. This activity aims to increase the knowledge and skills of Miri Village residents in maggot cultivation, the dependence of farmers on artificial feed can be reduced and replaced with feed from maggot cultivation. Activities carried out in the service consist of socialization and training on maggot cultivation. The socialization was in the form of exposure to the benefits and propagation of maggots, while the training materials were the practice of catching eggs, maintaining maggots, and harvesting maggots. The results of the activity showed an increase in participants' knowledge regarding maggot cultivation by 21.32%. The participants also showed interest in carrying out practical activities. The benefits of BSF cultivation include reducing household waste, producing maggots as animal feed, and producing organic fertilizer.</p>

<p>The efforts of production enhancement of sweet potato are limited by some constraints including some pest. One of the important pests is sweet potato weevil (Cylas formicarius Fabr.). The use fertilizer and kind of variety are important factors determining the yield of sweet potato. This study aims to examine the effect of manure on three varities of sweet potato and evaluate the yield of varieties test on sweet potato weevil, through choice test and no choice test. The research in field used Randomized Completely Block Design (RAKL) with two treatments. The varieties (Korea, Manohara, Madu) and manure (control, cow manure, chicken manure). Research in laboratory used three varieties and adult of C. formicarius. The result showed that granting of chicken manure on Manohara varieties gave the best response on a length of stem, number of leaves, fresh weight and weight of tubers. Granting of cow manure on Manohara and Madu Varieties give the weight of tuber stricken was less than Korea varieties. Choice test in Manohara varieties show the high population and in no choice test show Korea Varieties had high population of C. formicarius.</p>

This study aims to determine the effect of the bamboo ash and straw compost on brown planthopper and rice production. This research was conducted in Bakaran, Sukosari Village, Jumantono, Karanganyar in 12ndDecemberMarch 2017. The study was conducted using Complete Randomized Block Design (RCBD) in paddy fields consisting of 16 plots, each was 16 m2 with Bamboo Leaftreatment, Straw Compost, and Chemical Silica with SiO2of 200 kg-1ha dosage. The variables observed were: Population of brown planthopper, stem hardness, plant height, number of tillers, number of productive tillers, weight of 100 seeds, weight of filled seed, hollow seed weight and percentage of hollow seeds. The data obtained were analyzed by Analysis of Variance (ANOVA) and if there was a significant difference, it followed by Duncans Multiple Range Test (DMRT) at 5% level. The results showed that bamboo leaf ash and straw compost not significan increase the hardness of the rice plant stems and brown planthopper population. Straw compost has the highest potential compared to other treatments because it produces the hardest stem rice and the lowest brown planthoppers population at 11 Weeks. The application of silica from various sources has no direct role in rice production.

<p><em>Plutella xylostella</em> is one of cabbage’s main pests. Botanical insecticides as alternative of chemical insecticides need to be expand, one of them is mahogany seed extract. Mahogany seed exctract contains saponin and flavonoid as reported mortal to <em>P. xylostella</em>. This study aimed to know the effective concentration of mahogany seed extract to manage <em>P. xylostella</em> different larva instar and to know LC₅₀value of mahogany seed extract to <em>P. xylostella</em>. This method used was completely randomized experimental design (CRD). Two factors used were mahogany seed exctract concentrations (0 gL^-1, 5 gL^-1, 10 gL^-1, 20 gL^-1, and 40 gL^-1) and larva instar (first and third instar). Each treatment repeated four times. The results showed that percentage of larva mortality first instar higher than third instar. Concentration 20 gL^-1 of mahogany seed exctract effective to kill first instar larva, and concentration 40 gL^-1 effective for third instar. Percentage of pupa mortality highest in concentration 10 gL^-1 for first instar and concentration 40 gL^-1 for third instar larva. Antifeedant increased as concentration given, while the eating ability that higher in third instar was decreased. LC₅₀ for first instar larva was 2,6 gL^-1 and third instar was 13,7 gL^-1, meaned that mahogany seed extract more toxic to first instar than third instar larva.</p>

<p>Wheat <em>(Triticum aestivum)</em> is one of main food source with carbohydrates which is consumed by world people. The loss of wheat during storage is caused by pests attack. Flour beetle <em>(Tribolium castaneum)</em> is one of the main pests of wheat flour. Biological insectisidies is a solution to solve the attack of warehouse pests. The aim of research are to study the effectiveness of srikaya seeds on <em>T. castaneum</em> in wheat flour and to study the quality of wheat flour after the application srikaya seeds to <em>T. castaneum. </em>The research were be held in Pandan Rejo Village, Kebakkramat Sub-District, Karanganyar Regency on 105 asl altitude during September until October 2017. The research use Complete Randomized Design (CRD) with two factors of four repetitions. Dose treatment for Srikaya seeds consist of four levels of controls, 2.5 g/100 g wheat, 5 g/100 g wheat, and 10 g/100 g of wheat and the form of application consist of two kinds are 0.5 mm srikaya seed and 1 mm srikaya seed. Research variables which are observed were toxicity srikaya seed, imago mortality, moisture content, wheight shrinkage of wheat, color of wheat, and odor of wheat. The result show that LD50 of srikaya seed on a form 0.5 mm is 3.97 g/100 g wheat and form 1 mm is 4.70 g/100 g wheat. The application of the srikaya seed to minimize changes in quality wheat. The lowest shrinkage weight is 2.43 g and highest on the control of wheat color 5.805 g. control treatment from while to white murky scales (2). Scent control treatment of wheat does not become musty semlling scented (1).</p>
