Abstract

Imidacloprid is a synthetic chemical compound used as an insecticide product. Despite the benefits that insecticides provided in controlling plant pests and increasing crop yields, the use of insecticides was associated with side effects in humans The purpose of this study was to evaluate the active ingredient of imidacloprid 200 g/l in an insecticide formulation to ensure the safety of the pesticide for the applicator. This study was conducted based on appropriate toxicological tests and assessment based on pre-clinical tests in the form of evaluation of irritation and sensitization. The method used was descriptive quantitative based on the OECD 404, 405, and 406 guidelines for albino New Zealand rabbits and adult Dunkin Hartley albino guinea pigs. The results showed that the imidacloprid compound did not cause irritation symptoms in the eyes (cornea, iris, conjunctiva, and chemosis) and skin (erythema and edema) with a score of zero (0). In addition, the results of the sensitization test at a concentration of 12.5 - 100% did not show the formation of erythema which was indicated by a score of zero (0). In conclusion, imidacloprid 200 g/l did not caused irritation and sensitivity reactions in test animals so this compound is safe to use as an insecticide.

Abstract

Tanaman beracun oleander (Nerium oleander) memiliki potensi untuk mengendalikan hama utama tanaman jagung, salah satunya ulat grayak jagung (Spodopetera frugiperda). Namun demikian, studi ekstrak daun N. oleander yang disiapkan dengan menggunakan pelarut yang berbeda belum diketahui efektivitasnya dalam mengendalikan S. frugiperda. Penelitian ini bertujuan untuk mengetahui perbedaan berbagai pelarut ekstrak daun N. oleander terhadap terhadap mortalitas, konsumsi makan, dan kelulushidupan larva S. frugiperda. Penelitian melibatkan ekstraksi daun N. oleander berdasarkan perbedaan polaritas pelarut (n-hexane, etanol, metanol, air) untuk lima konsentrasi uji yang berbeda serta perlakuan kontrol yang diulang empat kali menggunakan Rancangan Acak Lengkap (RAL) pada larva S. frugiperda instar III. Hasil penelitian menunjukkan bahwa ekstrak kasar metanol daun N. oleander memberikan pengaruh penghambatan konsumsi pakan larva S. frugiperda sebesar 0,071 ± 0,028 g dibandingkan kontrol 0,642 ± 0,031 g. Selain itu, ekstrak kasar metanol daun N. oleander menunjukkan persentase mortalitas tertinggi sebesar 97,5 ± 0,50%, diikuti oleh ekstrak kasar air 70 ± 0,82%, ekstrak kasar etanol 57,50 ± 0,96%, dan ekstrak kasar n-hexane 50,00 ± 0,82%. Kelulushidupan larva, pupa, dan imago S. frugiperda menunjukkan nilai persentase terendah sebesar 2-3,4% ketika diaplikasikan ekstrak kasar metanol daun N. oleander. Secara keseluruhan, metanol adalah pelarut yang paling baik untuk mengekstrak daun N. oleander terhadap mortalitas, daya konsumsi, dan kelulushidupan larva S. frugiperda.

Abstract

Munia birds (Lonchura spp.) are pests that attack paddy plants during the reproductive phase. The traditional methods of controlling birds are considered less effective because birds can adapt to the tools used. This study aimed to determine the effectiveness of a metallic light-based bird-repellent prototype to reduce paddy yield loss. The experiment was conducted in Cileles Village paddy fields, Jatinangor Subdistrict, Sumedang Regency, West Java Province, Indonesia. The effectivity of the prototype was tested by measuring the effective distance (m2), counting the frequency of bird visits (number of visits), bird populations, and the level of paddy damage (%), and paddy yield (kg/64 m2). The result of the experiment showed that 3 m was an effectual deterrent factor for the prototype, thus the tool can protect paddy plants with an area of 28.26 m2. The frequency of bird arrivals in the treatment was 22.25 times, compared to 61.25 times in the control; the bird population in the treatment was 48.25 birds, while the control was 108.75 birds; the level of damage to paddy panicles in the treatment was 10.11%, compared to 37.79% in the control; and the production of paddy yield with the repellent was higher (33.37 kg/64 m2) than the control (23.09 kg/64 m2). This innovative prototype was potentially able to deter bird pests in the paddy fields.

Abstract

Buah sukun (Artocarpus altilis) merupakan komoditas lokal yang potensial namun belum dimanfaatkan secara optimal oleh masyarakat Desa Rancaekek Wetan. Rendahnya nilai jual dan kurangnya inovasi dalam pengolahan menyebabkan petani sulit memperoleh keuntungan. Tujuan dari kegiatan pengabdian ini adalah meningkatkan kapasitas masyarakat dalam mengolah sukun menjadi produk bernilai ekonomis melalui pelatihan dan sosialisasi berbasis pengalaman. Kegiatan dilaksanakan dalam rangka Orientasi Kehidupan Kampus (OKK) Universitas Padjadjaran dengan metode pendekatan experiential learning dan manajemen partisipatif. Sebanyak 21 warga desa mengikuti kegiatan sosialisasi, praktik, dan pengisian kuesioner evaluasi sebelum dan sesudah kegiatan. Hasil menunjukkan adanya peningkatan dengan tingkat pengetahuan pasca kegiatan yang tercermin dari wawasan ketahanan pangan (57,14%), pengenalan terhadap buah sukun (95,24%), dan pemahaman pengolahan sukun (90,48%). Namun, mayoritas besar peserta (85,71%) menyatakan belum memiliki rencana produksi secara konkret yang menunjukkan perlunya dukungan lanjutan agar hasil pelatihan dapat diimplementasikan.. Kegiatan ini membuktikan bahwa pendekatan edukasi langsung dapat mendorong peningkatan kapasitas masyarakat terkait pengolahan sukun. Oleh karena itu, program pendampingan lanjutan diperlukan untuk mendorong penerapan hasil pelatihan dan keberlanjutan usaha olahan sukun di tingkat rumah tangga.

Abstract

The fall armyworm (FAW), Spodoptera frugiperda, is one of the major pests of maize, exhibiting high adaptability and causing significant losses to agriculture in Indonesia. An environmentally friendly approach to controlling FAW infestations involves using local toxic plants, such as Cerbera odollam, also known as Bintaro, which contains cardenolide glycosides, saponins, and alkaloids with potential as botanical insecticides. This study aimed to evaluate the effect of the methanol extract of C. odollam leaves on the locomotion and exploration activities of FAW larvae. The test was conducted using the leaf dip method at concentrations of 0, 1000, 2000, and 4000 ppm, with six replications. The samples were then analyzed and observed using the Organism Video Tracking Application ToxTrac v2.96. Results showed that higher extract concentrations led to a decrease in larval speed, from 17.48 mm/s to 1.83 mm/s, and a reduction in exploration area, from 48 to 9. In addition, larval immobility duration (freeze activity) increased nearly sevenfold compared to the control. These findings indicate that C. odollam shows promise as a natural insecticide that repels FAW larvae by limiting their movement and exploratory behavior.

Abstract

Spodoptera frugiperda Smith is a major pest of corn plants. Information on the life cycle and survival of this pest is important for proper and effective control. This study was conducted to determine the life cycle and survival of S. frugiperda in several areas in West Java. This study was conducted from June to August 2020. Samples were taken from several areas divided into three categories: highlands in Lembang District (1,100 m asl), middlelands in Jatinangor District (858 m asl), and the lowlands in Tarikolot District (103 m asl). Sampling used the observation method to study the effect of differences in altitude on population, life cycle, and survival. The results showed that there was no significant difference in the development time of S. frugiperda among the three different areas. The average development time of S. fugiperda was 24.55 days (highlands), 24.36 days (middlelands), and 24.07 days (lowlands). The survival percentage of S. frugiperda from highland, middle, and lowland areas in the egg phase was 95.44%, 97.34%, and 96.89%, larval phase 98.46%, 98.65%, and 98.48%, and pupal phase 87.63%, 88.08%, and 93.43%. The sex ratio of S. frugiperda from the highlands was 1:1, from the middlelands was 1:1.28, and from the lowlands was 1:0.89. Location did not affect the width parameter of the head capsule in S. frugiperda. Based on the test results, it is known that the life cycle, survival, and sex ratio of S. frugiperda from several regions do not have significant differences.
