Abstract

Background: The use of nanoparticles in Indonesia has been developing and is now being applied across sectors, including agriculture, health, and industry. Nanoparticles derived from Cymbopogon nardus can be used as nanopesticides because they contain several compounds that suppress pathogen growth and reduce pest populations. Chitosan is an additional compound used in the fabrication of these nanoparticles. Methods: This research used materials and tools, including a PSA (Particle Size Analyzer), a SEM (Scanning Electron Microscope), Cymbopogon nardus, and chitosan. The research stages included extraction of Cymbopogon nardus, nanoparticle fabrication, PSA analysis, zeta potential measurement, and SEM observation. Results: The PSA test revealed that the Cymbopogon nardus nanoparticles had an average size of 907.2 nm. The zeta potential of the nanoparticles was –40.62 mV, indicating good electrostatic stability. SEM images showed that the nanoparticles had an irregular shape. Conclusions: The Cymbopogon nardus nanoparticles produced in this study, as characterized by PSA, zeta potential, and SEM analyses, demonstrated the expected characteristics of nanoparticles.

Abstract

Nematoda entomopatogen (NEP) adalah organisme mikroskopis berbentuk mirip cacing yang memiliki potensi besar sebagai agens pengendali hayati. Kediri merupakan salah satu daerah penghasil tebu utama di Indonesia. Nematoda Heterorhabditis mampu membunuh uret (Lepidiota stigma) sebagai hama utama tebu, sehingga menunjukkan potensi yang besar bagi Heterorhabditis sp. sebagai musuh alami hama tanaman tebu. Penelitian ini bertujuan untuk mengeksplorasi keberadaan Heterorhabditis sp. di lahan tebu Kediri melalui pengambilan sampel tanah dan identifikasi morfometrik. Eksplorasi Heterorhabditis diawali dengan pengambilan sampel tanah pada tanaman tebu sehat kemudian dilakukan baiting NEP. Nematoda entomopatogen yang diperoleh diisolasi menggunakan metode white trap dan difiksasi sebelum diidentifikasi. Hasil penelitian menunjukkan bahwa pada tanah lahan tebu di Kediri terdapat nematoda Heterorhabditis sp. Nematoda Heterorhabditis sp. yang ditemukan memiliki panjang tubuh 467,6 µm, Lebar tubuh 26,9 µm, panjang bulbus basal 13,7 µm, dan panjang ekor 36,2 µm. Nematoda entomopatogen yang diperoleh berasal dari genus Heterorhabditis dengan dugaan spesies Heterorhabditis americana. Spesies ini berpotensi untuk dikembangkan dalam berbagai formulasi biopestisida guna mendukung pengembangan Pengelolaan Hama Terpadu (PHT) di Indonesia.

Abstract

This article examines the strategy to increase the sales of "Dwi Dewii" ginger syrup in Kelurahan Bendo through rebranding and product diversification. Ginger syrup, known for its health benefits such as boosting immunity, faces challenges in marketing and sales, primarily due to conventional marketing strategies that only target adult consumers and are less appealing to younger audiences. This program aims to identify the gaps in current marketing strategies and develop new methods to enhance the product’s appeal and sales. The methodology used includes observation, interviews, and an analysis of existing packaging designs and marketing techniques. This community service project involved four lecturers and three students, collaborating with the primary partner, "Dwi Dewii" Ginger Syrup small-scale enterprise, and four other local small-scale enterprises producing traditional Blitar souvenirs in Kelurahan Bendo. The steps taken included redesigning the product packaging, providing training in digital marketing, and product diversification. Rebranding and diversification are expected to increase market appeal and broaden the consumer base, especially among younger demographics. The new packaging design aims to enhance the product's quality perception and attract a wider range of consumers. Product diversification is anticipated to improve customer satisfaction and boost sales volume. Furthermore, optimizing digital marketing through social media and e-commerce has proven effective in increasing visibility and consumer interaction, ultimately contributing to the economic growth of the partner small-scale enterprises.Artikel ini mengkaji strategi peningkatan penjualan produk sirup jahe "Dwi Dewii" di Kelurahan Bendo melalui pendekatan rebranding dan diversifikasi produk. Sirup jahe yang dikenal karena manfaat kesehatannya, seperti meningkatkan imunitas, menghadapi tantangan dalam hal pemasaran dan penjualan. Hal ini terutama disebabkan oleh strategi pemasaran konvensional yang hanya menjangkau kalangan usia dewasa dan kurang menarik bagi konsumen usia remaja. Program ini bertujuan untuk mengidentifikasi permasalahan dalam strategi pemasaran yang ada serta mengembangkan metode baru yang dapat meningkatkan daya tarik dan penjualan produk. Metode yang digunakan meliputi observasi, wawancara, dan analisis terhadap desain kemasan serta teknik pemasaran yang sedang diterapkan. Kegiatan pengabdian ini melibatkan empat dosen dan tiga mahasiswa, yang bekerja sama dengan mitra utama, yaitu UMKM Sirup Jahe Merah "Dwi Dewii", serta empat UMKM lainnya yang memproduksi oleh-oleh khas Kota Blitar di Kelurahan Bendo. Langkah-langkah yang dilakukan mencakup perancangan ulang kemasan produk, pelatihan pemasaran digital, dan diversifikasi produk. Rebranding dan diversifikasi diharapkan mampu meningkatkan daya tarik pasar serta memperluas segmentasi konsumen, termasuk kalangan remaja. Desain kemasan baru dirancang untuk memperbaiki citra kualitas produk dan menarik perhatian konsumen yang lebih luas. Diversifikasi produk diharapkan dapat meningkatkan kepuasan pelanggan dan volume penjualan. Selain itu, optimalisasi pemasaran digital melalui media sosial dan e-commerce dinilai efektif dalam meningkatkan visibilitas dan interaksi dengan konsumen, yang pada akhirnya berkontribusi pada pertumbuhan ekonomi mitra UMKM.

Abstract

This study aimed to analyze the influence of abiotic factors on the diversity of natural enemies in cocoa fields. The study was conducted from January to March 2025. Various traps were used, including yellow traps, light traps, pitfall traps, and visual observations. Identification showed that cocoa fields with misting applications had a higher number of natural enemies (1,052 individuals) compared without misting fields (658 individuals). The application of misting resulted in higher diversity indices (H'), richness (R'), and dominance (C'), as well as lower evenness (E') compared to untreated fields. These findings suggest that the misting system creates a more favorable microhabitat for natural enemy diversity, thus potentially strengthening the IPM approach in cocoa cultivation. Interestingly, the analysis showed that temperature had a significance value (sig) > 0.05, indicating that temperature did not show a significant correlation with the increase in the abundance of natural enemies, while humidity has a significance value (sig) < 0.05, which shows that humidity has a significant correlation, although statistically relatively small, with the increase in the abundance of natural enemies.

Abstract

This study aims to characterize the pesticide compounds in garlic (Allium sativum L.) extract nanoparticles and test their mortality effectiveness against armyworms (Spodoptera litura F.) in the laboratory. Nanoparticle synthesis was carried out using the ionic gelation method with chitosan-TPP, which was subsequently characterized using PSA, SEM, FT-IR, and GC-MS. The characterization results showed a particle size of 930.52 nm with a homogeneous distribution (PDI 0.147). GC-MS analysis successfully identified the main bioactive organosulfur compounds, namely diallyl disulfide (20.72%), diallyl trisulfide (14.16%), and diallyl tetrasulfide (5.79%). Bioactivity testing using the sandwich method at five concentration variations (0-1%) showed the highest mortality reaching 70% at a 1% concentration. Probit analysis yielded values of LC₅₀ 1.116% and LC₉₀ 1.720%, as well as LT₅₀ 5.117 days and LT₉₀ 9.893 days. Statistical test results indicated a significant difference (p<0.05) between all treatments and the control group. Thus, it can be concluded that the garlic extract nanoparticle formulation has the potential to be an effective nano-bioinsecticide, with a mode of action that is dose-dependent and time-dependent in controlling S. litura larvae.
