“…Hal tersebut diperkuat dengan data penelitian yang dilakukan oleh Sianipar et al [14] yang menemukan bahwa pengamatan dengan mikroskop pada larva hama wereng batang cokelat yang terkena ekstrak daun mimba menunjukkan warna tubuh cokelat agak kehitaman. Hal tersebut merupakan efek dari zat azadirachtin yang terdapat pada daun mimba yang dapat menghambat pertumbuhan dan perkembangan serangga, sehingga hama wereng batang cokelat yang terkena ekstrak daun mimba tidak mengalami pertambahan ukuran tubuh.…”

Pestisida nabati adalah pestisida yang bahan aktifnya berasal dari tumbuh-tumbuhan dan berkhasiat mengendalikan serangan hama pada tanaman. Pestisida nabati memiliki kelebihan yaitu mengandung senyawa fenol, alkaloid, saponin, quinon, xanthone yang mudah terurai di alam sehingga tidak mengandung residu berbahaya bagi tanaman maupun pada lingkungan. Tujuan penelitian ini adalah untuk mengetahui efektivitas pestisida nabati terhadap larva ulat hongkong (Tenebrio molitor) pada tanaman sawi (Brassica juncea). Metode penelitian yang digunakan yaitu metode eksperimen dengan desain penelitian yaitu terdiri atas 3 jenis esktrak yaitu ekstrak daun pepaya, daun mimba, dan daun sirsak, serta kontrol (tanpa esktrak) dengan 3 ulangan. Hasil yang diperoleh menunjukkan bahwa perlakuan pestisida nabati dari ketiga ekstrak tanaman berpengaruh terhadap mortalitas larva ulat hongkong pada tanaman sawi. Semua perlakuan memiliki persentase efikasi di atas 50 % dalam kurun waktu 24 jam setelah pengaplikasian (JSA), dengan ekstrak daun pepaya sebagai ekstrak terbaik dibandingkan ekstrak lainnya.

Arthrospira platensis mass culture contamination is a recurring concern. Salinity alteration appears to be a promising approach, given that A. platensis can withstand various salinities. In addition, biopesticide is also expected to eliminate the bacteria. Therefore, it is critical to investigate the effects of salinity and biopesticide on the growth, nutritional value, and bacterial diversity of A. platensis mass culture. A completely randomized design was used, with five salinity treatment levels: 5 ppt (S5B), 10 ppt (S10B), 15 ppt (S15B), 20 ppt (S20B), and 25 ppt (S25B), with 0.5 ml/L of biopesticide Azadirachta indica applied on days 2 and 4. The growth rate was calculated using daily density and biomass, and on day 7, carbohydrates, proteins, lipids, and pigments were determined. Furthermore, the contamination test and bacterial diversity were determined using Total Plate Count and Next-Generation Sequencing, respectively. The results showed that the S15B had the fastest growth rate and the largest carbohydrate content. However, S5B produced the best results in terms of protein, chlorophyll, and phycocyanin content, while S25B produced the most carotene and lipids. Proteobacteria were the most abundant in all NGS samples. The number of OTU treatments obtained for A (NCD7), B (NCD0), and C (S15BD7) were 646, 636, and 286, respectively. Moreover, C (S15BD7) was the most effective treatment to reduce bacterial diversity contamination, in which several bacterial diversity, including Acidobacteriota, Chloroflexi, Gemmatimonadota, Myxococcota, and Desulfobacterota, were eliminated completely. As a result of the salinity adjustment and the use of biopesticides, the mass culture of A. platensis was able to grow more quickly and contain more nutrients while having less bacterial diversity.
