Abstract

Chili is a type of plant that is consumed almost every day by almost all of the world's population. Increasing the yield of chili plants will ensure the availability of chilies on the market. One effort to increase the amount of chili production is by choosing the right fertilizer based on the type of chili planted. In this review article, we discuss the influence of chemical and or non-chemical fertilizer types which are related to physiological aspects, for example the number of leaves, plant height, and total chlorophyll content. By knowing a lot of information regarding fertilization of chili plants, it is hoped that it can help in efforts to increase production so that it can meet people's needs for chilies.

Abstract

Silver nanoparticles have recently become one of the nanomaterials that are widely developed as antibacterial agents because they have a broad spectrum of activity against both Gram-positive and Gram-negative bacteria. This study aimed to synthesize silver nanoparticle using ecoenzyme solution as a reducing agent and to characterize its characters. This study was conducted in two main stages, i.e. biosynthesis which was carried out by reacting ecoenzyme solution with silver nitrate solution, and the next stage was the characterization of silver nanoparticle, including morphological analysis using spectrophotometer, scanning electron microscope (SEM), and particle size analyzer (PSA) as well as analysis of antibacterial activity. The results showed that silver nanoparticles were successfully synthesized. Morphological analysis using SEM showed that silver nanoparticles were cubic, rectangular, or spherical, while the size analysis was around at 83.64 nm, although visually, there were no visible color change to dark brown and no peak at a wavelength of 400-600 nm. Antibacterial activity analysis showed that ecoenzyme-derived silver nanoparticles had the ability to inhibit both gram-positive and gram-negative bacteria, and specifically had better antibacterial properties for gram-positive bacteria compared to the control. These results indicated that silver nanoparticle using ecoenzyme as bioreductor has the potential to be used as antibacterial agents for multidrug-resistant bacterial infections.

Abstract

Keterbatasan keterampilan ekonomi kreatif masih menjadi salah satu kendala dalam meningkatkan kemandirian ekonomi rumah tangga, khususnya bagi warga Paguyuban Perumahan Home Bekonang, Sukoharjo. Sebagian besar ibu rumah tangga belum memiliki keterampilan untuk menghasilkan produk kreatif yang bernilai ekonomi. Selain itu, kondisi lingkungan perumahan yang berdekatan dengan kawasan industri menyebabkan ketidaknyamanan akibat bau limbah. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, sikap, dan keterampilan warga melalui pelatihan pembuatan lilin aromaterapi sebagai salah satu produk ekonomi kreatif berbasis rumah tangga. Metode pelaksanaan meliputi identifikasi kebutuhan melalui observasi dan wawancara, sosialisasi program, pretest, penyuluhan, pelatihan dan praktik langsung pembuatan lilin aromaterapi, penerapan teknologi tepat guna, pendampingan selama dua minggu, serta evaluasi melalui posttest dan penilaian kualitas produk. Hasil kegiatan menunjukkan bahwa pelatihan berhasil meningkatkan pengetahuan peserta dengan nilai N-Gain sebesar 0,86 yang termasuk dalam kategori tinggi. Selain itu, aspek sikap memperoleh rata-rata skor 3,48 dengan kategori sangat baik, aspek keterampilan memperoleh rata-rata skor 3,59 dengan kategori sangat baik, dan kualitas produk lilin aromaterapi yang dihasilkan oleh lima kelompok peserta memperoleh rata-rata skor 3,50 dengan kategori sangat layak. Program ini juga menghasilkan luaran berupa panduan pembuatan lilin aromaterapi serta meningkatkan motivasi peserta untuk mengembangkan usaha ekonomi kreatif berbasis rumah tangga. Dengan demikian, pelatihan pembuatan lilin aromaterapi terbukti efektif dalam meningkatkan kapasitas warga Perumahan Home Bekonang sekaligus berpotensi mendukung pengembangan usaha ekonomi kreatif dan kemandirian ekonomi warga secara berkelanjutan.
