Abstract

Food resilience is a shared responsibility between the government and the community to meet the food needs of all Indonesian citizens, particularly from West Aceh. One effort to optimize food resilience is to increase superior natural resources (SDA) such as rice. The use of chemicals to prevent rice weevil pests from attacking rice stores and ineffective fertilization management in rice fields often have negative impacts on both health and the environment. This socialization activity aimed to introduce the use of plant preservative powder as an alternative to controlling rice weevil pests in rice storage and the use of soil test kits to independently measure nutrient conditions in rice fields. This activity was carried out in Peunia Village, Kaway XVI District by involving members of the Ingin Maju Farmers Group as service partners. The results of this empowerment activity showed the importance of understanding the actual condition of the soil through soil analysis using soil test kits, such as pH meters and BWD tools. This knowledge aimed to minimize the possibility of a decline in soil carrying capacity (degradation) which can have an impact on rice production. The production of rice reserves can also be controlled from pest attacks such as rice weevils (Sitophilus oryzae) by using preservative powder made from aromatic leaves. Increasing farmer skills in these two methods were expected to support the realization of food resilience and more sustainable and environmentally friendly agricultural management.

Abstract

Due to some doubts regarding the morphological identification of fruit flies, molecular identification is necessary to more clearly determine the origin of the insect. With the PCR RAPD method, which can identify genetic markers, it can effectively and quickly distinguish closely related species. RAPD is used as a tool to create genetic maps, identify strains, species, populations, and systematics of various organisms. RAPD can differentiate laboratory populations that are morphologically indistinguishable. So the purpose of this study is to more clearly determine the identity of the fruit flies found, both morphologically and molecularly. This research method is a purpose sampling method, where fruit fly samples are obtained from traps using attractants in red guava plantations. The fruit fly species found in the red guava plantation location are Bactrocera sp., and Bactrocera kinabalu. The results of the study found that the fruit fly species Bactrocera sp. found in the village of Sawit Rejo was identified morphologically as having many similarities with Bactrocera papayae except for its abdominal pattern. To confirm the taxonomic status of Bactrocera sp. For further clarification, it is necessary to use molecular identification of cytochrome oxidase 1 and phylogenetic genes, with DNA sequencing results (500 bp) showing that the Bactrocera sp. species has a homology level of 88% with Bactrocera carambolae from the Genbank collection. The phylogenetic tree shows that Bactrocera sp. has ancestors from China.

Abstract

Refugia plants are able to control pest insects in cultivation plants, the benefits of refugia plants can become microhabibtat natural enemies. This research was conducted to see the diversity of natural enemy insects in the planting of shallots (allium cepa) by utilizing various flowering plants as edge plants. This research was conducted in the Teuku Umar University Experimental Garden. The research began in October-December 2023. This study used a non-factorial plot split plot design method with 5 levels and 4 treatments, namely: T0 = without refugia plants, T1 = Zinnia Elegans, T2 = Marigold Plants, T3 = Cosmos Plant, T4 = Zinnia elegans + marigold + cosmos. The results showed that insect identification there were 7 types of orders and 20 species of insect species. The result of the natural enemy diversity index value with the calculation of H 'data in all treatments is moderate. The results of the independence index of the type with the highest value are in the combination treatment reaching the E'1 value, which means according to E => 0.6 the level of compliance of the type is classified as high. In the yield of shallots for the highest lime weight, there is a combination of 1.890 kg.Keywords: Refugia, natural enemies, diversity, types of evenness

Abstract

Kutu beras (Sitophilus oryzae) menjadi hama utama yang menyerang produk simpanan beras di gudang sehingga dapat menurunkan kualitas dan kuantitas beras. Diperlukan upaya pengendalian hama kutu beras yang bersifat ramah lingkungan seperti pemanfaatan bioinsektisida berbahan alami dari tumbuhan agar mengurangi dampak negatif penggunaan insektisida sintetik terhadap lingkungan. Penelitian ini bertujuan untuk menganalisis mortalitas dan antifidan hama kutu beras setelah diaplikasikan serbuk daun belimbing wuluh dan pandan wangi. Metode penelitian yang digunakan adalah metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 8 perlakuan dan 3 kali ulangan. Data penghambatan konsumsi pakan diperoleh melalui perhitungan kehilangan bobot beras selam 21 Hari Setelah Aplikasi (HSA). Hasil penelitian menunjukkan serbuk daun belimbing wuluh dan daun pandan wangi efektif sebagai insektisida nabati dalam mengendalikan hama kutu beras dengan persentase mortalitasnya melebihi 50%. Persentase mortalitas tertinggi pada aplikasi daun belimbing wuluh dengan konsentrasi 50 g dan pandan wangi 40 g. Uji penghambatan makan memperlihatkan hasil bahwa semakin tinggi konsentrasi serbuk diberikan, maka nilai persentase kerusakan beras akan semakin menurun akibat aktivitas senyawa metabolit sekunder saponin, flavonoid, dan tanin yang terdapat pada tanaman. Senyawa metabolit sekunder saponin dan flavonoid pada daun belimbing wuluh dan pandan wangi bekerja sebagai senyawa antifeedant yang dapat menghambat aktivitas makan hama kutu beras.

Abstract

Storing rice for a long time in the warehouse has the potential to be attacked by warehouse pests, namely rice weevil insect (Sitophilus oryzae). Rice weevil attacked on storage rice caused a decrease in the quality and quantity of rice, so environmentally friendly pest control is needed, such as the used of bioactive plant compounds as botanical insecticides. This research aimed to see the effect of bioactive compounds from the combined powder of fragrant pandan (Pandanus amaryllifolius) and wuluh starfruit (Averrhoa bilimbi) leaves on the mortality of the rice weevil pest S. oryzae. The method of this research used a non-factorial Completely Randomized Design (CRD) experimental method with 4 concentration levels of botanical insecticide combination powder, that were 30, 40, 50 and 60 g. The research results showed that the combination of fragrant pandan and wuluh starfruit leaf powders contained bioactive compounds were steroids, terpenoids, saponins, flavonoids, phenolics and tannins. The activity of the bioactive compounds saponins, flavonoids, phenolics and tannins worked as inhibitors of insect feeding (antifeedant) and caused the mortality of S. oryzae. The highest mortality percentage reaching 85% was obtained after applicated by a concentration of 50 g. The increase in mortality of the S. oryzae pest occurred every week, until mortality reached more than 80% in the 3rd week was obtained in treatment concentrations of 30 g (84.2%) and 50 g (85%).
