“…The concentration treatment of the two extracts that was most effective in reducing larval feeding activity causing a decrease in the average feeding area was the highest concentration treatment of 3% with the smallest average feeding area found in the n-hexane extract treatment of 2.273 mm (Table 4). The antifeedant potential of papaya leaves supported by previous research by Rahayu et al, (2020) who conducted a papaya leaf extract antifeedant test against S. litura. The results showed that papaya leaf extract concentration of 50% produced an antifeedant index of 100%.…”

One of the agricultural commodities that has a high selling value and consumption level is shallot (Alium ascalonicum). However, the productivity of shallots is known to be susceptible to plant-destroying organisms, such as the shallot caterpillar (Spodoptera exigua). Currently, most shallot farmers control S. exigua using synthetic insecticides. Synthetic insecticides are poisonous and use for a long time period will cause resistance to pests and environmental pollution. One of the natural ingredients that has the potential as a botanical insecticide is papaya (Carica papaya). This study aimed to determine the effectiveness and concentration of n-hexane and ethanolic extracts of papaya leaves which are the most effective against toxicity and inhibition of the feeding power of S. exigua second instar larvae. The extract was obtained by gradual maceration of n-hexane (non polar) and ethanol (polar) solvents. Test the secondary metabolite content of papaya leaves using Thin Layer Chromatography (TLC). The results showed that the ethanol extract was the most effective extract in causing toxicity to larvae with the highest percentage of 96.67%. Meanwhile, n-hexane extract was more effective in inhibiting larval feeding than ethanol extract with the lowest feeding area of 2,27 mm. The most effective concentration of against toxicity and feeding inhibition of larvae is concentration 3%. The LC50 value of the ethanol extract was 0.0207% and the n-hexane extract was 0.0459%. Both extracts are known to contain compound groups, namely tannins, terpenoids, flavonoids, and alkaloids.

“…The explanation is in line with that of F1 emergence. A study has also shown that pawpaw leaf extract exhibited prevented feeding by Spodoptera litura larvae (Rahayu et al, 2020). A group of researchers have demonstrated that terpenoids and phenols present in plant material inhibit larval feeding and can also disrupt hormonal balance or make food unpalatable (Jose and Sujatha, 2017).…”

“…These indigenous plants are readily available, easy to prepare and have been used as medicine for centuries. These plants have been demonstrated to possess secondary metabolites and anti-insect odors at varying concentrations (Jagella and Grosch, 1999;Pierre-Leandri et al, 2002;Lee et al, 2020;Rahayu et al, 2020).…”

Maize production system is challenged by a lot of biotic and abiotic stressors. Among the biotic stressors, the maize weevil is infamous for causing severe damage to stored maize, reducing both qualitative and quantitative qualities. Incessant use of synthetic insecticide to manage maize weevil has led to a public outcry and a need for more eco-compatible options. Botanicals provide a cheap, safe and easy-to-make, and eco-friendly option for maize weevil management. This study was designed to assess the toxicity of four medicinal plant powders on some parameters of maize weevil. The study was conducted in June-July, 2020 in the Food Science laboratory of Catholic University of Cameroon, Bamenda. Plant powders of Carica papaya seeds, Cupressus macrocarpa leaves, Piper nigrum seeds and a control (no-input) were assessed. All the parameters assessed were significantly influenced by botanical powders (P < 0.05). The highest F1 emergence suppression was observed from piper treatments, followed by cypress and pawpaw treatments. The highest and lowest maize weight loss after storage were 21.0g and 13.25g from control and piper treatments respectively. The highest germination percentage was 95.0%, followed by 80.0%, 75.0% and 52.5% from piper (bush pepper or black pepper, cypress, pawpaw and control treatment, respectively. High repellency potential was observed from botanicals and that of piper can be described as a ‘very good repellant’ and ‘good repellant’ for the other botanicals. The highest adult weevil mortality was 80.05, recorded from piper. The current study demonstrate that botanical powders can play a significant role in maize weevil management. Piper seed powder is highly recommended for management of maize weevil. In addition, it is recommended that botanical powders be incorporated into integrated pest management strategies in order to guarantee safe, healthy and quality maize in storage. Such activities are in line with the objective of sustainable development goals (SDG).

Abstrak: Keberadaan organisme pengganggu tumbuhan masih menjadi kendala dalam kegiatan produksi pertanian di Desa Malangsari, Karawang. Penggunaan pestisida sintetis dalam mengendalikan hama dan penyakit menimbulkan dampak negatif bagi manusia dan lingkungan. Tujuan dari pengabdian ini adalah memberikan pengetahuan dan keahlian praktis pada kelompok tani dengan jumlah 12 orang di Desa Malangsari untuk mampu memanfaatkan tanaman potensial sebagai bahan baku pestisida nabati yang diolah menggunakan dry solar chamber. Metode yang dilakukan untuk kegiatan PkM diintegrasikan dengan kegiatan KKN Mahasiswa, berisi kegiatan analisis permasalahan dan potensi wilayah yang dilakukan secara purposive sampling pada petani, simulasi dan penyuluhan penggunaan dry solar chamber dan pembuatan formulasi tepung pestisida nabati, serta monitoring dan evaluasi dengan melakukan wawancara setelah dilakukannya kegiatan PkM. Hasil didapatkan jika penggunaan dry solar chamber mampu memerangkap energi panas dengan kisaran suhu 35,6° - 45,3° C dan mengefisiensikan proses pengeringan. Formulasi pestisida nabati yang dibuat memiliki kemampuan dalam mengendalikan serangga uji. Berdasarkan tingkat pemahaman petani, terjadi peningkatan pemahaman dari 27% menjadi 100% dalam hal pengendalian OPT menggunakan pestisida nabati sebagai alternatif dari pestisida sintetik.Abstract: The presence of plant pest organisms is still an obstacle in agricultural production activities in Desa Malangsari, Karawang. The use of synthetic pesticides in controlling pests and diseases has a negative impact on humans and the environment. The purpose of this service is to provide knowledge and practical skills to a group of 12 farmers in Desa Malangsari to be able to utilize potential plants as raw materials for vegetable pesticides processed using a dry solar chamber. The method carried out for PkM activities is integrated with Student Community Service activities, containing problem analysis activities and potential areas carried out by purposive sampling of farmers, simulation and counseling on the use of dry solar chambers and making vegetable pesticide flour formulations, as well as monitoring and evaluation by conducting interviews after PkM activities. The results obtained if the use of a dry solar chamber is able to trap heat energy with a temperature range of 35.6° - 45.3° C and streamline the drying process. The vegetable pesticide formulation made has the ability to control the test insects. Based on the level of understanding of farmers, there was an increase in understanding from 27% to 100% in terms of pest control using vegetable pesticides as an alternative to synthetic pesticides.
